Background Tube thoracostomy (TT) insertion is a commonly performed procedure in trauma that is standardised, but the optimal removal technique based on the timing in relation to the respiratory cycle remains controversial. Methods A prospective study was undertaken at a major trauma centre in South Africa over a 4-year period from January 2010 to December 2013, and included all patients with pneumothorax secondary to thoracic stab wounds. TTs were removed by either end of inspiration technique (EIT) or end of expiration (EET) technique and the rate of recurrent pneumothorax (RPTX) following removal was compared. We hypothesized that there is no difference in the rate of RPTX between the end inspiratory (EI) and end expiratory (EE) removal technique. Results A total 347 patients were included. Of the 184 TTs removed by EIT, there were 17 (9%) RPTXs. Of the 163 with EET, there were 11 RPTXs (7%), (9% versus 7%, chi-squared, P = 0.395). Of the total 28 (9%) patients with RPTXs following removal of chest tubes, two (7%) required reinsertion of chest tube (0.5% (1/184) in EIT and 0.6% (1/163) in EET, P = 0.747). Conclusions Timing of TT removal in relation to the respiratory cycle does not appear to influence the incidence of RPTX in patients with thoracic stab wounds. Technique of removal may well be a more important consideration and more attention must be focused on refining the optimal technique.

Background Flexor digitorum profundus (FDP) avulsion injuries occur following forced hyperextension of the distal interphalangeal joint (DIPJ). Methods We highlight a case report of FDP avulsion injury fixed using a single hole of a plate in combination with a cortical screw to act as a washer. A search and discussion of the literature is included.

The spectrum of injury associated with anterior abdominal stab wounds (SWs) is well established. The literature in the specific setting of isolated omental evisceration is limited.We reviewed our experience of 244 consecutive patients with established indications for laparotomy over an eight year period at a major trauma centre in South Africa.Of the 244 patients (93% male, mean age: 27 years), 224 (92) underwent immediate laparotomy (IL). Twenty were initially observed and eventually required a laparotomy (delayed laparotomy, DL). The mean time from injury to decision for laparotomy was3 h in 92% (224/244),6 h in 6% (14/244),12 h 2% (4/244) and18 h in 1% (2/244). Ninety-eight per cent (238/244) of laparotomies were positive and 96% of the positive laparotomies (229/238) were considered therapeutic. The mostly commonly injured organ encountered on laparotomy were small bowel, stomach and colon.The most commonly injures encountered are intestinal and gastric. Clinicians must remain vigilant as injuries may be subtle.

Background and Aims:The management of duodenal trauma remains controversial. This retrospective audit of a prospectively maintained database was intended to clarify the operative management of duodenal injury at our institution and to assess the risk factors for leak following primary duodenal repair.Materials and Methods:This was a retrospective study undertaken at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa. Operative techniques used for duodenal repair were recorded. Our primary outcome was duodenal leak in the postoperative period. Patients from January 2012 to December 2016 were included. All duodenal injuries were graded according to the American Association for the Surgery of Trauma (AAST) grading. Only patients who had a primary repair were included in the final analysis.Results:During the five-year data collection period, a total of 562 patients underwent a trauma laparotomy; of which 94 patients sustained a duodenal injury. A primary pyloric exclusion and gastro-jejunostomy (PEG) was performed in three patients. These three were then excluded from further analysis. Of the 91 primary duodenal repairs, seven (8%) subsequently leaked. These were managed by PEG in three and by secondary repair and para-duodenal drainage in four. The two physiological parameters most associated with subsequent leak were lactate and pH level. There was a significantly higher mortality rate for those who leaked vs those who did not leak. Chi-squared test revealed a significant difference in the leak rate between AAST I (0%), AAST-II (1.6%) and AAST-3 (66.7%) grade injuries (p Conclusion:The trend towards primary repair of duodenal injuries appears to be justified. However duodenal leak remains a significant risk in certain high risk patients and strategies to manage injuries in this subset requires further work.

Background: Imaging is an integral part of trauma management and the huge burden of trauma in South Africa places substantial pressures on radiology resources. This study aims to provide a holistic overview of the burden of trauma imaging and the cost of trauma to a busy CT scanning facility at a tertiary hospital in South Africa. Methods: We set out to describe and quantify the impact of blunt poly-trauma on CT scanning services at Grey’s Hospital in Pietermaritzburg. We aimed to provide a holistic assessment in terms of use of equipment and staff, cost to the hospital and overall usage of CT scanning. Results: Over the four-year study period, 1572 patients required a CT scan following blunt torso trauma (mean age: 30 years, 81% males). Of the 1572 patients, 625 had a chest radiograph (40%), 383 a cervical spine X-ray (24%), 347 a pelvic X-ray (22%), 292 a skull X-ray (18%), 193 a limb X-ray (12%), 133 an abdominal radiograph (8%), and 86 a FAST scan (5%). The 1572 CT included: 967 head, 568 neck, 65 chest, 241 abdominal, 228 pelvic, 12 upper limb, 38 lower limb and 394 had full body (Pan) CT scan. The mean total cost of the CT scanning for blunt poly-trauma is ZAR 12 000. The total cost of CT scanning for blunt poly-trauma is 0.92% of the total hospital expenditure. Roughly 7.8% of the total hours worked by the CT scanner over the time period under review was dedicated to blu nt poly-trauma. Conclusion: Blunt poly-trauma is a preventable disease, which has a major financial impact on the healthcare system in general. This study has documented the tremendous burden it places on an already stretched CT scanning service.

Introduction Organ evisceration following abdominal stab wound (SW) is currently considered as an absolute indication for mandatory laparotomy due to the high incidence of associated intra-abdominal injuries, but literature describing the spectrum of organ injury encountered is limited. Materials and methods We reviewed our experience of 301 consecutive patients who were subjected to mandatory laparotomy over an eight-year period at a major trauma centre in South Africa. Results Of the 301 patients with organ evisceration, 92% were male (mean age: 28 years). Ninety per cent (270/301) of the laparotomies were positive (85% (229/270) therapeutic, 15% (41/270) non-therapeutic). The frequencies of eviscerated organs were small bowel (70%), large bowel (26%), and stomach 3%. Three (1%) patients had combined evisceration of more than one of the above organs. The most commonly injured organs were small bowel and large bowel. The mean length of hospital stay was nine days. Seven patients required intensive care admission. The morbidity rate was 21% and mortality was 2%. Conclusions The spectrum of injury associated with abdominal SW with organ evisceration is similar to smaller published series. Multiple organ injuries are common. The most commonly eviscerated organs were small bowel, large bowel and stomach, while the most commonly injured organs were small bowel and large bowel.

Introduction: Discrepancy in outcomes between urban and rural trauma patients is well known. We reviewed our institutional experience with the management of gunshot wounds (GSWs) in the specific setting of car hijacking and focused on clinical outcome between rural and urban patients. Methods: A retrospective review was conducted at a major trauma centre in South Africa over an 8-year period for all patients who presented with any form of GSWs in car hijacking settings. Specific clinical outcomes were compared between rural and urban patients. Results: A total of 101 patients were included (74% male, mean age 34 years). Fifty-five per cent were injured in rural areas and the remaining 45% (45/101) were in the urban district. Mean time from injury to arrival at our trauma centre was 11 hours for rural and 4 hours for urban patients (p < 0.001). Seventy-six per cent (76/101) sustained GSWs to multiple body regions. Sixty-three of the 101 (62%) patients required one or more operative interventions. In individual logistic regressions adjusted for sex and number of regions injured, rural patients were 9 (95% CI: 1.9-44.4) and 7 (95% CI: 2.1-24.5) times more likely than urban patients to have morbidities or required admissions to intensive care respectively. The risk of death in rural patients was 36 (95% CI: 4.5-284.6) times higher than that of urban patients. Conclusions: Patients who sustained GSWs in carjacking incidents that occurred in rural areas are associated with significantly greater morbidity and mortality compared with their urban counterparts. Delay to definitive care is likely to be the significant contributory factor, and improvement in prehospital emergency medical service is likely to be beneficial in improving patient outcome.

Background: Self-harm behaviour is a major public health problem that is commonly underreported. This study reviews the spectrum of these self inflicted injuries managed by a major trauma centre in South Africa. Methods: A retrospective review of the regional trauma registry was undertaken over a five-year period from December 2012 to December 2017 at the Pietermaritzburg Metropolitan Trauma Service (PMTS) in South Africa. All patients who were admitted after they had sustained an injury as a result of self-harm were included. Results: During the five-year study period, a total of 179 patients were included. The mean age was 29 years (SD12) and there were 139 (77%) males and 40 (23%) females. Of these, 16 had a previously established psychiatric diagnosis and two had a prior history of having sustained self-harm. The previously diagnosed psychiatric illnesses included mood dysphoria disorders (5), schizophrenia (3), substance abuse and dependency (1), anti-social personality disorder (1) and unspecified (6). The mechanism was penetrating trauma in 47 (26%). The penetrating mechanisms included stab wounds (SW) in 33, gunshot wounds (GSW) in 10, broken glass in 2 and a single impalement. Blunt mechanisms accounted for the remaining 131 (73%) injuries. The most common mechanism of blunt self-harm was hanging in 101 patients. This was followed by vehicular related trauma (8), jumping in front of a train (1) and jumping from a height (1). In 17 patients the exact mechanism of the blunt trauma was unclear. There was no statistical difference in the mechanism of injury between male and female patients. There were 38 (28%) men and 9 (23%) women who sustained a penetrating injury and there were 100 (72%) male and 31 (78%) female patients who had a blunt mechanism of injury. A total of 53 CT scans were obtained, 40 chest X-rays, 9 abdominal X-rays and 2 ultrasounds. There were 113 neck injuries, 68 head injuries, 24 abdominal injuries, 15 upper limb and 15 lower limb injuries and four facial injuries. A total of 32 operations were performed. These included laparotomy (14), neck exploration (5), tracheostomy (4). A total of 22 patients developed a complication. Conclusion: Self-inflicted injury is not uncommon and frequently requires investigation and or surgical treatment. Patients who sustain such an injury constitute a distinct vulnerable group who are under researched. Future research on this vulnerable patient group is needed.&nbsp

Background: Humans come into contact and interact with an array of animals in a number of areas and environments. We set out to review our experience with animal-related injuries in Pietermaritzburg, KwaZulu-Natal, South Africa. Methods: All patients who sustained an injury secondary to an interaction with an animal in the period December 2012–December 2017 were identified from the Hybrid Electronic Medical Registry (HEMR). Results: There were 104 patients in the study sample. The mean age of patients in the study was 32.8 years, with a range from 1 to 76 years old. 75% (n = 78) were male and 25% (n = 26) female. Out of the 104 animal-related injuries, 67 were blunt trauma, 39 penetrating trauma and 3 a combination of blunt and penetrating trauma. The species causing trauma included dogs (53), horses (29), cows (18), buffalo (1), warthog (1), impala (1) and a single goat (1). The median time from injury to hospitalisation was 46.62 hours (range from 0 to 504 hours). Injuries occurred to the head (n = 32), face (n = 9), neck (n = 32), abdomen (n = 22), urogenital system (n = 6), upper limb (n = 39) and lower limb (n = 39). The Injury Severity Score (ISS) mean for the patients was 8.16, the range 1–4, the median 9 and the standard deviation 6.88. In 49 patients the treatment was non-operative. In the remaining 55 patients, a total of 68 operative procedures were required. Operations included wound debridement/surgical washout (n = 38), laparotomy (n = 9), arterial repair/ligation (n = 8), skin graft (n = 4), craniotomy (n = 5), fasciotomy (n = 2), amputation (n = 1), and placement of an ICP monitor (n = 1). 49 of these operations were for patients with dog bite injuries. The mean hospital stay was 0.13 days with a range of 0–4 days. Four patients were admitted to the Intensive Care Unit (ICU) and two patients died. Conclusion: Human interactions with animals may result in injuries which require surgical treatment. The most common animal injury is a dog bite but in the case of the larger domestic farm animals, blunt force type injuries and goring can result in significant injuries which require complex surgical interventions.

Hanging is a common form of self-harm, and emergency care physicians will not infrequently be called upon to manage a survivor.Despite the relative frequency of the injury, there is a paucity of literature on the topic and the spectrum and incidence of associated injuries are poorly described.To review experience with management of victims of hanging at a major trauma centre in South Africa.All patients treated by the Pietermaritzburg Metropolitan Trauma Service following a hanging incident between December 2012 and December 2018 were identified from the Hybrid Electronic Medical Registry. Basic demographics were recorded, and the management and outcome of each patient were noted.During the 6-year period under review, a total of 154 patients were seen following a hanging incident. The mean age was 29.4 years. There were 24 females (15.6%) and 130 males (84.4%). The vast majority (n=150; 97.5%) had attempted suicide, and only 4 hangings (2.5%) were accidental. A total of 92 patients (60.9%) had consumed alcohol prior to the incident. There were 23 patients with a Glasgow Coma Score (GCS)lt;9 (severe traumatic brain injury (TBI)), 14 with a GCS of 9 - 12 (moderate TBI) and 117 with a GCSgt;12 (mild TBI). A total of 7 patients (4.5%) required intensive care unit admission, and 25 (16.2%) required intubation. The following extracranial injuries were documented on computed tomography scans: hyoid bone fractures (n=2), cervical spine fracture (n=10), mandible fracture (n=4) and oesophageal injury (n=1). Intracranial pathology was evident on 27.0% of scans, with the most common finding being global cerebral ischaemia. The mortality rate was 2.5% (4/154).Hanging is a common mechanism of self-harm. It is associated with significant injuries and mortality. The acute management of hanging should focus on airway protection followed by detailed imaging of the head and neck. Further work must attempt to include mortuary data on hanging.

Penetrating neck injuries are serious as there is a high concentration of vital structures in close proximity to each other in a compressed anatomical area. Penetrating neck injuries can be immediately life threatening due to massive bleeding from vascular structures or due to airway compromise. Injury to the digestive tract in the neck may also result in delayed and potentially life-threatening conditions. The majority (79%) of penetrating neck injuries can be managed conservatively. The clinician caring for such a patient requires a structured and comprehensive approach to managing these injuries. This article will provide a general overview of penetrating neck injuries, including resuscitation, epidemiology, surgical management and the use of appropriate imaging.

OBJECTIVE Routine immobilisation of the cervical spine in trauma has been a long established practice. Very little is known in regard to its appropriateness in the specific setting of isolated traumatic brain injury secondary to gunshot wounds (GSWs). METHODS A retrospective study was conducted over a 5 year period (January 2010 to December 2014) at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa in order to determine the actual incidence of concomitant cervical spine injury (CSI) in the setting of isolated cerebral GSWs. RESULTS During the 5 year study period, 102 patients were included. Ninety-two per cent (94/102) were male and the mean age was 29 years. Ninety-eight per cent of the injuries were secondary to low velocity GSWs. Twenty-seven (26%) patients had cervical collar placed by the Emergency Medical Service. The remaining 75 patients had their cervical collar placed in the resuscitation room. Fifty-five (54%) patients had a Glasgow Coma Scale (GCS) of 15 and underwent plain radiography, all of which were normal. Clearance of cervical spine based on normal radiography combined with clinical assessment was achieved in all 55 (100%) patients. The remaining 47 patients whose GCS was

Cerebral gunshot wounds (GSW) are highly lethal injuries. To date, only one clinical scoring system to predict mortality in a developing world setting has been described. This is the Baragwanath mortality prediction score (“ABC”: admission blood pressure, brain matter spillage and consciousness level). We performed a retrospective review of prospectively entered data for a cohort of patients with isolated cerebral GSWs over a 5-year period (January 2010–December 2014) in our institution. We aimed to validate the Baragwanath ABC mortality prediction score in our population. During the 5-year study period, 102 patients with isolated cerebral GSWs were reviewed, 22% (22/102) of which died. Based on the total ABC score (1–5), the mortality was 0% for 1, 21% for 2, 67% for 3, 92% for 4, and 100% for 5. The ABC score has a sensitivity of 82% (95% CI 60–95%), specificity of 96% (95% CI 89–99%), PPV of 86% (95% CI 66–96%) and NPV of 95% (95% CI 86–99%). The Baragwanath mortality prediction score accurately predicts non survival of patients with a cerebral GSW in our patient cohort. Further validation studies in other populations are required before this system can be widely adopted.

Introduction: This study examines the nature of trauma laparotomies performed primarily by trainees and those performed under the direct supervision of a consultant.Materials and Methods: A retrospective review was undertaken at the Pietermaritzburg Metropolitan Trauma Service (PMTS), South Africa. All patients who underwent a trauma laparotomy were included. Admission physiology, organ injury and outcome were assessed. Statistical comparison using STATA was performed. Chi-squared analysis was used for categorical variables and unpaired T-test for physiology.Results: A total of 562 patients for trauma laparotomy were identified. Ninety percent (506/562) were male and the mean age was 30 years. The in hospital mortality was 7% (40/562). A consultant was present at 35% of cases (197/562). Consultantlead operations were found to have a higher rate of mortality 16% vs 2% (32/197 vs 8/365: p < 0.001) and ICU 45% vs 25% (89/197 vs 91/365: p < 0.001) than trainee only.Significant differences in many parameters of admission physiology were identified. Consultant-lead procedures had a higher lactate (3.7 vs 2.9: p 0.0043), respiratory rate (RR) (22 vs 20: p 0.0005), heart rate (HR) (102 vs 96: p 0.0035) and a lower systolic blood pressure (SBP) (115 vs 122: p 0.0001) diastolic blood pressure (DBP) (69 vs 73: p 0.0350) pH (7.34 vs 7.36: p 0.0216) base excess (BE, mEq/L) (-4.1 vs -2.5: p 0.0036) and bicarbonate (HCO3, mEq/L) (21.3 vs 22.5: p 0.0043) than trainee only procedures. Consultants were more likely to be called in for a gunshot than a stab wound (p < 0.001). Of the solid organ injuries, consultants are more likely to be called in for cases with liver injury 23% vs 16% (45/197 vs 58/365: p 0.005) and pancreatic injury 15% vs 3% (30/197 vs 11/365: p < 0.001).Conclusion: Trainees can safely undertake a subset of trauma laparotomies. However, patients with deranged physiology and complex hepatobiliary injuries should be operated on directly by a consultant.

BackgroundCar hijacking, known as “carjacking”, is a form of aggravated robbery of a vehicle from the driver frequently involving firearm and is common in South Africa. There is, however, little literature on the spectrum of injuries sustained by victims of car hijacking. The study aimed to describe the spectrum of gunshot wound-related (GSW) injuries and review our experience of management of victims of car hijacking in our trauma center based in South Africa.MethodsA retrospective review was conducted during an 8-year period from January 2010 to January 2018 on all patients who presented with any form of GSW after a car hijacking incident.ResultsDuring the 8-year study period, a total of 101 patients were identified. Seventy-four percent were male (75 of 101) and the mean age was 34 years. The mean time from injury to arrival at our trauma center was 7 hours (rural district: 10 hours, urban district: 4 hours; pDiscussionThe spectrum of injuries from GSW related to car hijacking commonly involves close range GSWs to multiple body regions. Torso trauma is common and a substantial proportion of victims require major operative interventions. The mortality from these injuries is significant.Level of EvidenceLevel III.

This review focuses on burn care in low- and middle-income countries (LMICs). It attempts to put the burden of disease in perspective by showing that burn care is under-resourced across the spectrum of LMICs and by interrogating the ethical dilemmas and challenges that staff face in caring for burn patients in this environment, with a focus on South Africa. More specifically, it will attempt to address the following issues: the threshold for utilizing the intensive care unit (ICU), how to balance treatment against cost, the percentage burn considered survivable and how it should be determined, the use of skin from both cadavers and living related donors, and the appropriate ethical guidelines for LMICs.

Intra-abdominal vascular injury (IAVI) is uncommon but continues to be associated with high mortality rates despite technological advances in the past decades. In light of these ongoing developments, we reviewed our contemporary experience with IAVI in an attempt to clarify and refine our management strategies and the outcome of these patients.We retrospectively reviewed the charts of all patients admitted between January 2011 and December 2014 at a major trauma centre in South Africa who were found to have an IAVI during laparotomy for trauma. We collected demographic and clinical data including mechanism of injury, location and severity of the injury, concurrent injuries, physiologic parameters and clinical outcome.We identified 110 patients with IAVIs, of whom 98 had sustained penetrating injuries (55 gunshot wounds and 43 stab wounds). There were 84 arterial injuries (including 21 renal and 17 mesenteric) and 74 venous injuries (including 21 renal and 17 inferior vena caval). Combined venous and arterial injuries were found in almost one-third of patients (34 [30.9%]). Fifty-seven patients (51.8%) required intensive care admission. The overall mortality rate was 28.2% (31 patients); the rate was 62% for aortic injuries and 47% for inferior vena cava injuries. Liver injury, large bowel injury, splenic injury and elevated lactate level were all associated with a statistically significantly higher mortality rate.The mortality rate for IAVI remains high despite decades of operative experience in high-volume centres. Open operative techniques alone are unlikely to achieve further reduction in mortality rates. Integration of endovascular techniques may provide an alternative strategy to improve outcomes.Les lésions vasculaires intraabdominales (LVIA) sont rares, mais elles sont toujours associées à un taux de mortalité élevé, malgré les progrès technologiques des dernières décennies. À la lumière de ces renseignements, nous avons passé en revue l'expérience récente en matière de LVIA afin de clarifier et de parfaire nos stratégies de prise en charge et d'améliorer les résultats des patients.Nous avons examiné de manière rétrospective les dossiers de tous les patients admis entre janvier 2011 et décembre 2014 dans un grand centre de traumatologie d'Afrique du Sud chez qui une laparotomie a révélé la présence d'une LVIA. Nous avons recueilli des données démographiques et cliniques portant notamment sur le mécanisme lésionnel, la localisation et la gravité de la lésion, les blessures concomitantes, les paramètres physiologiques et l'issue clinique.Nous avons recensé 110 patients atteints de LVIA, dont 98 avaient subi des blessures par pénétration (55 causées par un projectile d'arme à feu et 43 par une arme blanche). Nous avons dénombré 84 lésions artérielles (dont 21 rénales et 17 mésentériques) et 74 lésions veineuses (dont 21 rénales et 17 touchant la veine cave inférieure). Dans l'ensemble, nous avons constaté des lésions veineuses et artérielles chez près du tiers des patients (34 patients, soit 30,9 %). Cinquante-sept patients (51,8 %) ont dû être admis à l'unité des soins intensifs. Le taux de mortalité global était de 28,2 % (31 patients); il était de 62 % pour les cas de lésions aortiques et de 47 % pour les lésions touchant la veine cave inférieure. Les lésions au foie, au gros intestin et à la rate ainsi que les taux élevés de lactate ont tous été associés à une hausse statistiquement significative du taux de mortalité.Le taux de mortalité associé aux LVIA reste élevé malgré des décennies d'expérience chirurgicale dans des centres de traumatologie traitant un grand nombre de patients. Les techniques opératoires ouvertes seules sont peu susceptibles de donner lieu à une baisse de ce taux. L'intégration des techniques endovasculaires pourrait constituer une solution de rechange pour améliorer les résultats.

Background The management of colon injuries has steadily evolved over the course of the last half century. So too has the management of renal trauma. It is not clear from the literature as to whether concomitant colon and renal injuries carry increased risk of morbidity and mortality, and whether this combination of injuries necessitates a specifically tailored management approach. Methods A retrospective review was carried out for the period January 2012 to December 2016. All patients over the age of 18 years who were subjected to laparotomy for penetrating trauma (gunshot wounds or stab wounds) and who sustained an intra-operatively proven colonic injury were included in this study. Operative management and outcomes were investigated. A direct comparison was made between patients with a combined colonic and renal injury and those with only a colonic injury. Results Over the five-year period a total of 268 patients sustained a colonic injury. The 239 patients with a colonic injury (Group A) were compared to the 29 patients with a combined colonic and renal injury (Group B). Regarding the management of the colonic injuries, there were no differences in the rates of primary repair, anastomosis, exteriorization, or damage control surgery between groups A and B. As for the management of the renal injury, 14 were not explored at laparotomy; in 12 a nephrectomy was performed and in 3 the renal injury was repaired. The nephrectomy cohort were more likely to have undergone damage control surgery, to be admitted to ICU, to receive a colostomy, and had higher mortality. While there was no difference in the need for damage control surgery or mortality between groups, Group B had a significantly greater need for ICU admission. Morbidity was similar between the two groups – in particular, there was no difference in the rates of either gastro-intestinal complications or acute kidney injury between the two groups. Conclusion In patients with combined colon and renal injuries, it seems reasonable to treat each organ on its own merit, without the expectation of increased morbidity or mortality. In the non-damage control setting, most colonic injuries may be safely repaired, and a peri-renal haematoma that is not expanding or actively bleeding may be safely left alone.

Objective To review the ability of junior doctors (JDs) in identifying the correct anatomical site for central venous catheterization (CVC) and whether prior Advanced Trauma Life Support (ATLS) training influences this. Design We performed a prospective, observational study using a structured survey and asked a group of JDs (postgraduate year 1 [PGY1] or year 2 [PGY2]) to indicate on a photograph the exact site for CVC insertion via the internal jugular (IJV) and the subclavian (SCV) approach. This study was conducted in a large metropolitan university hospital in South Africa. Results A total of 139 JDs were included. Forty-four per cent (61/139) were males and the mean age was 25 years. There were 90 PGY1s (65%) and 49 PGY2s (35%). Overall, 32% (45/139) were able to identify the correct insertion site for the IJV approach and 60% (84/139) for the SCV approach. Of the 90 PGY1s, 34% (31/90) correctly identified the insertion site for the IJV approach and 59% (53/90) for the SCV approach. Of the 49 PGY2s, 29% (14/49) correctly identified the insertion site for the IJV approach and 63% (31/49) for the SCV approach. No significant difference between PGY1 and 2 were identified. Those with ATLS provider training were significantly more likely to identify the correct site for the IJV approaches [OR = 4.3, p = 0.001]. This was marginally statistically significant (i.e. p > 0.05 but Conclusions The majority of JDs do not have sufficient anatomical knowledge to identify the correct insertion site CVCs. Those who had undergone ATLS training were more likely to be able to identify the correct insertion site.

BackgroundThis study set out to review a large series of trauma laparotomies from a single center and to compare those requiring damage control surgery (DCS) with those who did not, and then to interrogate a number of anatomic and physiologic scoring systems to see which best predicted the need for DCS.MethodsAll patients over the age of 15 years undergoing a laparotomy for trauma during the period from December 2012 to December 2017 were retrieved from the Hybrid Electronic Medical Registry (HEMR) at the Pietermaritzburg Metropolitan Trauma Service (PMTS), South Africa. They were divided into two cohorts, namely the DCS and non-DCS cohort, based on what was recorded in the operative note. These groups were then compared in terms of demographics and spectrum of injury, as well as clinical outcome. The following scores were worked out for each patient: Penetrating Abdominal Trauma Index (PATI), Injury Severity Score, Abbreviated Injury Scale-abdomen, and Abbreviated Injury Scale-chest.ResultsA total of 562 patients were included, and 99 of these (18%) had a DCS procedure versus 463 (82%) non-DCS. The mechanism was penetrating trauma in 81% of cases (453 of 562). A large proportion of trauma victims were male (503 of 562, 90%), with a mean age of 29.5±10.8.

Background Cerebral gunshot wounds (CGSWs) represent a highly lethal form of traumatic brain injury, and triaging these patients is difficult. The prognostic significance of the serum lactate level in the setting of CGSWs is largely unknown. Objectives To examine the relationship between elevated serum lactate levels and mortality in patients with isolated CGSWs. Methods A retrospective review of the regional trauma registry was undertaken at the Pietermaritzburg Metropolitan Trauma Service, South Africa, over a 5-year period from 1 January 2010 to 31 December 2014. All patients with an isolated CGSW were included. Results A total of 102 patients with isolated CGSWs were identified. Of these, 92.2% (94/102) were male. The mean age (standard deviation) was 29 (8) years, and the in-hospital mortality rate was 21.6% (22/102). The mean serum lactate level was significantly higher among non-survivors than among survivors (6.1 mmol/L v. 1.3 mmol/L; p Conclusions CGSWs are associated with significant mortality, and a raised serum lactate level appears to be an independent predictor of in-hospital mortality. It is a potentially useful adjunct in the resuscitation room for identifying patients with a very poor prognosis.

Background and Aims:Selective nonoperative management of abdominal stab wound is well established, but its application in the setting of isolated omental evisceration remains controversial. The aim of the study is to establish the role of selective nonoperative management in the setting of isolated omental evisceration.Materials and Methods:A retrospective study was conducted over an 8-year period from January 2010 to December 2017 at a major trauma center in South Africa to determine the outcome of selective nonoperative management.Results:A total of 405 consecutive cases were reviewed (91% male, mean age: 27 years), of which 224 (55%) cases required immediate laparotomy. The remaining 181 cases were observed clinically, of which 20 (11%) cases eventually required a delayed laparotomy. The mean time from injury to decision for laparotomy was Conclusion:Selective nonoperative management for abdominal stab wound in the setting of isolated omental evisceration is safe and does not result in increased morbidity or mortality. Clinical assessment remains valid and accurate in determining the need for laparotomy but must be performed by experienced surgeons in a controlled environment.

IntroductionThe modern concept of damage control surgery (DCS) for trauma was first introduced less than three decades ago. This audit aims to describe the spectrum and outcome of patients requiring DCS, to benchmark our experience against that reported from other centres and countries and to distil the pertinent teaching lessons from this experience.MethodsAll patients over the age of 15 years undergoing a laparotomy for trauma over the period from December 2012 to July 2016 were retrieved from the trauma registry of the Pietermaritzburg Metropolitan Trauma Service, South Africa. Physiological parameters and visceral injuries were assessed. Statistical analysis was performed using STATA V.15.0.ResultsA total of 562 patients underwent trauma laparotomy during the period under review. The mechanism was penetrating trauma in 81% of cases (453/562). A great proportion of trauma victims were male (503/562, 90%), with a mean age of 29.5±10.8. A total of 99 of these (18%) had a DCS procedure versus 463 (82%) non-DCS. Out of the 99 who required DCS, there were 32 mortalities (32%). The mean physiological parameters for the DCS patient demonstrated acidosis (pH 7.28±0.15) with a raised lactate (5.25 mmol/L±3.71). Our primary repair rates for enteric injuries were surprisingly high.ConclusionJust under 20% of trauma laparotomies require DCS. In this cohort of patients, the mortality rate is just under one-third. Further attention must be paid to refining the appropriate indications for DCS as the margin for error in such a cohort is very small and poor decision-making is difficult to correct. The major lesson from this analysis is that the decision to perform DCS must be made early and communicated appropriately to all those managing the patient.
