Aim and objective To study the profile, indications, related complications, and predictors of decannulation and mortality in patients who underwent tracheostomy in the pediatric intensive care unit (PICU). Materials and methods Retrospective analysis of prospectively collected data of tracheostomies was done on patients admitted at PICU. Demographics, primary diagnosis, indication of tracheostomy, and durations of endotracheal intubation, mechanical ventilation, and tracheostomy cannulation were recorded. The indication was recorded in one of the four categories—upper airway obstruction (UAO), central neurological impairment (CNI), prolonged mechanical ventilation, and peripheral neuromuscular disorders). Results Two hundred ninety cases were analyzed. UAO (42%) and CNI (48.2%) were main indications in the halves of the study period, respectively. Decannulation was successful in 188 (64.8%) patients. Seventy-seven percentage UAO patients were decannulated successfully [OR (odds ratio); 95% CI (confidence interval), 2.647; 1.182–5.924, p = 0.018]. Age

Objective The aim of the study was to investigate the association of urinary albumin:creatinine ratio (ACR) with regard to the outcome of sepsis patients and to study the trends of ACR with severity of disease, organ dysfunction, microcirculation status, the use of inotrope, and mechanical ventilation use, and length of pediatric intensive care unit (PICU) stay. Materials and methods In the prospective observational study, the patients with varying categories of sepsis admitted in the PICU with stay >24 hours were enrolled consecutively. Urine samples were collected at the time of admission (ACR1), 12 hours (ACR2), and 24 hours (ACR3). Results One hundred and thirty-eight patients including 56 cases of sepsis, 31 of severe sepsis, 22 of septic shock, and 29 of multiorgan dysfunction syndrome (MODS) cases were analyzed. There were 29 (21%) deaths. ACR (median, IQR) was significantly higher in nonsurvivors [ACR1 198.9 (111.2–329.4) vs 124.5 (59.37–294.5), p 0.03], [ACR2 213.8 (112.5–350) vs 117.8 (62.6–211.9) p 0.008], [ACR3 231.8 (99.9–441.2 vs 114.4 (44.1–240.3), p 0.005]. The ACR is increased progressively with the increasing severity of sepsis (p < 0.001). The performance of ACR operative characteristics was compared with that of PRISM and PELOD scores. In deceased, ACR was significantly correlated with blood pH, lactate, and base deficit. A cutoff value of ACR 102.7 mg/g had sensitivity 86.2%, specificity 40.4%, positive predictive value 27.8%, and negative predictive value 91.7%. The use of inotropes, mechanical ventilation (>48 hours), and mortality was significantly higher in patients with ACR >102 mg/g. The probability of death varied from 17.6 to 19% in the first 24 hours of admission. ACR was significantly cheaper as compared to PRISM score and PELOD score estimations. Conclusion Urinary ACR, a cost-effective tool, correlates with the severity of sepsis and associated morbidity and mortality in children.

Objective: The objective is to study the intra- and postoperative cardiopulmonary complications, metabolic derangements, and mortality in the recipients of orthotopic liver transplantation (OLT). Materials and Methods: Medical records of all children who underwent OLT at our institution from January 2003 to December 2019 were reviewed, and the clinical and laboratory data were collected. Results: Eighty-two patients (48 males) underwent living-related OLT and one received cadaveric liver. The median age of recipients was 6 years (range: 4 months–16 years). The two common indications for OLT were biliary atresia (n = 27, 32.9%) and Wilson's disease (n = 20, 24.3%). Common metabolic problems during intraoperative phase included hypokalemia (43.9%) and hyperglycemia (57.3%). The mean duration of postoperative ventilation was 35.8 ± 51.4 h. Fifty-two patients were extubated within 24 h of surgery. Pleural effusion was most common present in 52 patients postoperatively. It did not interfere with mechanical ventilation. Hypertension, hypotension, and oliguria were recorded in 28, 31, and 22 patients, respectively. There were 11 graft rejection episodes. Ten children required re-operations. There were 4 (4.8%) early deaths, aged ≤1 year, in the first 2 weeks of transplantation. Conclusion: Medical and surgical complications are common in patients after liver transplantation. Intensive monitoring and laboratory workup help in detection of these complications. Early and 1-year survival rates are comparable to that in the developed world.

In recent past, revolution in medical technology resulted in improved survival rates and outcomes of critically ill children. Unfortunately, its impact relating to morbidity is not well documented. Although survival rates of these critically ill children who are medically fragile and technology-dependent have improved, we as health professionals are still in the learning curve to improve the quality of life of these children at home. Factors such as support from society, infrastructure, and funding play an important role in technology-dependent child care at home. In this review, commonly prescribed home-based medical technologies such as home ventilation, enteral nutrition, renal replacement therapy, and peripherally inserted central catheter, which are useful for quick revision, are described.

BACKGROUND: Limited adult data suggest that airway driving pressure might better reflect the potential risk for lung injury than tidal volume based on ideal body weight, and the parameter correlates with mortality in ARDS. There is a lack of data about the effect of driving pressure on mortality in pediatric ARDS. This study aimed to evaluate the effect of driving pressure on morbidity and mortality of children with acute hypoxemic respiratory failure. METHODS: This retrospective cohort study was performed in a tertiary level pediatric ICU. Children who received invasive mechanical ventilation for acute hypoxemic respiratory failure (defined as [Formula: see text] < 300 within 24 h after intubation), in a 2-y period were included. The cohort was divided into 2 groups based on the highest dynamic driving pressure (ΔP, calculated as the difference between peak inspiratory pressure and PEEP) in the first 24 h, with a cutoff value of 15 cm H(2)O. RESULTS: Of the 380 children who were mechanically ventilated during the study period, 101 children who met eligibility criteria were enrolled. Common diagnoses were pneumonia (n = 51), severe sepsis (n = 24), severe dengue (n = 10), and aspiration pneumonia (n = 7). In comparison to the group with high ΔP (ie, ≥ 15 cm H(2)O), children in the group with low ΔP (ie, < 15 cm H(2)O) had significantly lower median (interquartile range) duration of ventilation (5 [4–6] d vs 8 [6–11] d, P < .001], ICU length of stay (6 [5–8] d vs 12 [8–15] d, P < .001], and more ventilator-free days at day 28 (23 [20–24] vs 17 [0–22] d, P < .001). Logistic regression analysis also suggested driving pressure as an independent predictor of morbidity after adjusting for confounding variables. However, there was no statistically significant difference in mortality between the 2 groups (17% in low ΔP vs 24% in high ΔP, P = .38). Subgroup analysis of 65 subjects who fulfilled ARDS criteria yielded similar results with respect to mortality and morbidity. CONCLUSIONS: Below a threshold of 15 cm H(2)O, ΔP was associated with significantly decreased morbidity in children with acute hypoxemic respiratory failure.

Objective: It was hypothesized that heated humidified high flow nasal cannula (HFNC) is non-inferior to non- invasive ventilation (NIV) for preventing reintubation in high risk children. Design: Prospective randomized clinical non-inferiority trial Setting: Single centre study in a 12-bed multidisciplinary paediatric intensive care unit (PICU) in Delhi. Patients: All children (1month -18years) receiving invasive mechanical ventilation longer than 48 hours and ready for scheduled extubation. Intervention: Heated humidified high flow nasal cannula(HFNC) or Non-invasive ventilation (NIV) Measurements and Main Results: Of total 230 patients enrolled, 139 were analysed (3 left against medical advice), out of which 70 (50.4%) received NIV and 69 (49.6%) HFNC. Mean duration of intubation was 150.8 ±74.3 hours in NIV group vs 138.5 ±81.9 hours in HFNC group (p= 0.16). Out of 139 children, 15(10.8%) were re-intubated; 6 (8.6%) in the NIV group vs 9 (13%) in the HFNC group (absolute difference 4.4%; p= 0.42). Median time to re-intubation did not differ between the group; NIV group 4 hours (IQR 1.7-12.5hours) vs HFNC group 3.7 hours (IQR 2-4hours) (absolute difference, 0.3 hours; p= 0.50). Mean post extubation PICU length of stay was significantly lower in HFNC group (3.5 ±2.5 days) vs NIV group (4.1± 2.3days; p= 0.01). There were multiple reasons for failure of assigned intervention which were comparable in both groups. These included : stridor, impaired consciousness (fall in GCS>2), haemodynamic instability, inability to clear airway, increased work of breathing, hypoxemia, respiratory acidosis. There was no mortality in either group within 48 hours of extubation. Conclusion: Among high-risk children who had undergone extubation, HFNC therapy was found to be non-inferior to NIV with respect to the re-intubation rate.

OBJECTIVE To study the safety profile of blind bronchial sampling in mechanically ventilated children. DESIGN Prospective interventional study. SETTING Tertiary level pediatric intensive care unit of a multispecialty hospital. PATIENTS Children aged 1 month to 16 years on mechanical ventilator for ≥48 h, were assessed by clinical pulmonary infection score for ventilator-associated pneumonia (VAP). INTERVENTIONS Blind bronchial sampling was performed following standard procedural guidelines. The hemodynamic, ventilation parameters, and arterial blood gases done before, and in next 24 h post procedure were recorded and compared. MEASUREMENTS AND MAIN RESULTS Among the 40 enrolled children, VAP was suspected at 5.8 ± 3.7 days post intubation with insignificant increase in median (IQR) PELOD score to 15 (11-23) from 13.5 (11-23) (P value 0.29). A statistically significant increase in mean blood pressure (75.5 ± 14.7 to 79.1 ± 14.2, P 0.04) and transient drop in SpO2 (98.2 ± 2.3 to 92.2 ± 9.2, P

Status Asthmaticus is a common reason for Emergency Room visits in children. Most of the asthma flares are successfully managed by use of β agonist and steroids. If these therapies fail to halt the progression of asthma, a number of medical therapies may be used to treat it. However, the data supporting the use of these therapies are conflicting. We present successful use of Extracorporeal Membrane Oxygenation and isoflurane in a child with Refractory Status Asthmaticus.

Hyperleukocytosis in pertussis has a correlation with disease severity. We describe a 5-week-old infant with severe pertussis and hyperleukocytosis requiring mechanical ventilation. Baby developed refractory hypoxemia. Two cycles of exchange transfusion were done on different occasions. Exchange transfusion resulted in significant improvement in oxygenation and hemodynamic parameters. Exchange transfusion is a viable treatment option in pertussis hyperleukocytosis complicated by refractory hypoxemia or persistent features of Systemic Inflammatory Response Syndrome.

Extracorporeal membrane oxygenation (ECMO) is a standard modality to treat refractory hypoxemia in pediatric acute respiratory distress syndrome (ARDS) in developed countries. However, it’s usage is limited in developing countries like India, where very few tertiary care PICU centres have used it with success. We report a case of 11 months old infant with necrotising bacterial pneumonia with severe ARDS and septic shock who failed on conventional and high frequency mechanical ventilation, but was successfully managed with veno-arterial ECMO support.

Objective: The objective of the study was to evaluate the etiology of hospital-acquired hyponatremia (HAH) and its effects on morbidity and mortality in the Pediatric Intensive Care Unit (PICU) patients. Design: This study design was a prospective observational case–control study. Setting: this study was conducted at tertiary care PICU. Materials and Methods: All consecutive cases admitted with at least one measured serum sodium (PNa) value were evaluated. Those with normal admission PNa were followed till they develop hyponatremia (PNa < 35 mEq/L) 7 days or PICU discharge whichever was earlier. Results: During the study period, 123 (19.6%) cases developed HAH and 126 patients remained isonatremic (control group). The admission PNa 138.8 ± 3.03 mEq/L decreased to 132 ± 2.58 mEq/L (drop of 6.68 ± 3.39 mEq/L, P < 0.001) in HAH cases. The use of antidiuretic hormone (ADH)-stimulating drugs (odds ratio [OR]: 2.83, P = 0.01), postsurgical status (OR: 2.95, P = 0.006), and fluid intake ml/kg (OR: 1.0, P = 0.001) were found to be significant risk factors in HAH group on multivariate analysis. HAH cases had prolonged PICU stay (P = 0.000) and mechanical ventilation (P = 0.01), but no difference in the mortality when compared to controls. Conclusions: HAH is associated with increased fluid intake, presence of ADH-stimulating drugs or conditions, and postsurgical status and has an adverse effect on the outcome of PICU patients.

To describe the utility of flexible fiberoptic bronchoscopy for the diagnosis and management in the neonatal ICU.A retrospective, medical chart review was conducted in neonates who underwent flexible fiberoptic bronchoscopy over a period of 7 years. Besides demographic data and diagnostic findings, the results of medical and/or surgical interventions done by treating neonatologist were recorded.88 bronchoscopies were performed in 83 neonates, of which 37 were done through endotracheal tube. Indications included persistent need for mechanical ventilation (32), persistent atelectasis (21), and stridor (27). Most common airway anomalies diagnosed included tracheobronchomalacia (20), laryngomalacia (18), subglottic stenosis (7), choanal atresia (4), laryngeal cleft (4), and tracheoesophageal fistula (4). Surgical interventions were undertaken in 17 cases (9 tracheostomies and 2 cases of slide tracheoplasty).Flexible fiberoptic bronchoscopy can be beneficial for the diagnosis and management of neonates with persistent or undiagnosed respiratory problems.

Acute left ventricular dysfunction in children justifies aggressive treatment because of the high potential for complete recovery. The options for providing mechanical support to the failing heart in a child include extracorporeal membrane oxygenation, left ventricular assist devices, and the use of the intra-aortic balloon pump (IABP). The IABP is a commonly used method of temporary circulatory support in adults. However, despite the availability of pediatric size balloons, the usage of IABP for temporary circulatory support in children has not been widespread. Current case report, first from India in pediatric age group, aims to aware the pediatric intensivist about the role of IABP in providing temporary mechanical cardiovascular support in managing patients with refractory low cardiac output state.

WHO 2005 data points to sepsis in form of pneumonia, diarrhea, and neonatal sepsis as major killers of children in the resource limited countries of Asia and Africa, However, currently there are no specific published guidelines for treatment of severe sepsis in resource limited circumstances. An expert panel drawn from all over India, met to discuss and draw guidelines for management of pediatric septic shock that are applicable to resource limited countries. The group evaluated strength of published data and expert opinion for clinical practice and feasibility of delivery of care at various levels of resource constraints, keeping in view unique patient population and limited availability of equipment and resources. Issues for discussion included simplified definitions and reliable clinical indicators of septic shock, fluid resuscitation, graded inotropic and vasopressor support, corticosteroid therapy, timing and indication for endotracheal intubation and use of positive end expiratory pressure/mechanical ventilation, initial empirical antibiotic therapy, correction of hypoglycemia and glycemic control, role of immunoglobulin, and blood and blood products. Evidence has been graded and levels of evidence indicated wherever applicable. The expert group recognized and listed potential barrier to implementation of existing American College of Critical Care Medicine guidelines for treatment of septic shock in resource limited countries, adopted simplified definitions of septic shock, tachycardia, tachypnea and hypotension, and developed step-wise algorithmic approach for treating septic shock. Evidence based treatment recommendations include early oxygen therapy, fluid resuscitation based on blood pressure, use of dopamine in fluid refractory shock, early use of antibiotics, early intubation and assisted ventilation, correction of hypoglycemia and emphasis on use of physical examination for achieving therapeutic endpoints. These interventions have brought the mortality down and can be easily applied even at primary and/or secondary level health facilities. Interventions recommended after above steps were based on consensus rather than evidence. These include stress dose steroid therapy, use of vasopressors and inodilators, and central venous pressure and echocardiography to guide fluid and vasoactive drug infusion, which require transfer to a pediatric intensive care unit. Strict glycemic control is not recommended. Evidence on benefit of several other interventions viz. use of vasopressin as vasopressor, use of intravenous immunoglobulins, renal replacement therapy, use of plasmapheresis etc. is emerging. The expert group observed that further research evaluating individual components of guidelines and relative benefit of each of these interventions in resource limited setting is needed, as also the benefit of adherence with standardized protocol. Pediatric sepsis guidelines suitable for resource limited settings are presented for resource limited settings. Several unresolved issues were identified for further research.

Chest trauma is one of the important causes of mortality and morbidity in pediatric trauma patients. The complexity, magnitude, and type of lung injury make it extremely challenging to provide optimal oxygenation and ventilation while protecting the lung from further injury due to mechanical ventilation. Independent lung ventilation is used sporadically in these patients who do not respond to these conventional ventilatory strategies using double-lumen endotracheal tubes, bronchial blocker balloons, etc. However, this equipment may not be easily available in developing countries, especially for pediatric patients. Here, we present a case of severe chest trauma with pulmonary contusion, flail chest, and bronchopleural fistula, who did not respond to conventional lung protective strategies. She was successfully managed with bronchoscopy-guided unilateral placement of conventional endotracheal tube followed by single lung ventilation leading to resolution of a chest injury.

This study was aimed to evaluate the utility and benefits of flexible fiberoptic bronchoscopy (FFB) prior to tracheostomy decannulation. Besides demographic data, initial cause of tracheostomy, primary diagnosis, pre-tracheostomy and pre-decannulation bronchoscopic findings and duration of tracheostomy were collected from medical charts. The type of active intervention following bronchoscopy and outcome after decannulation were recorded. Departmental decannulation policy and procedure were used in all patients. Forty-nine tracheostomized patients who underwent decannulation attempt were included. The median age of the children at the time of decannulation was 3 years (range 4 months–16 years). The median duration of tracheostomy was 8 months (range 1–86 months). Prolonged mechanical ventilation was the commonest indication for tracheostomy. There were 45 abnormal findings on FFB in 36 patients. Airway granulation was the commonest abnormality (23/45, 51%). Successful decannulation without any intervention was possible in 23 (46.9%) cases. 12 of these had normal bronchoscopy. Fifteen (30.6%) patients required surgical interventions before attempting decannulation. In five patients decannulation failed, while in six children decannulation was not attempted after FFB. Pre-decannulation flexible fiberoptic bronchoscopy in children with tracheostomy helps in identifying the possible causes of decannulation failure and helps in deciding the appropriate intervention.

Methemoglobinemia can be congenital or acquired. Acquired methemoglobinemia occurs as a result of ingestion of some substances such as toluene, nitrates. Patient presents with cyanosis which is not explainable by the respiratory or cardiac cause. Most frequently used drug in treatment is methylene blue. We report a case of a patient with severe acquired methemoglobinemia in 14 months old baby, due to ingestion of toluene. He was cyanosed which was refractory to oxygen therapy and without any cardiac and respiratory disease. He had persistent high levels of methemoglobin, despite giving multiple doses of methylene blue and exchange transfusion. Finally, methemoglobin levels were controlled by automated RBC exchange transfusion and intralipid infusion.

Objective: To compare the effects of noninvasive positive pressure ventilation(NIPPV) and oxygen (OX) therapy in post-extubated patients on re-intubation rate, length of PICU and hospital stay and mortality. Methods: It was randomized interventional study.All patients on mechanical ventilation (MV) for more than 48 hours were assessed and were enrolled only after fulfilling inclusion criteria. Patients were randomized prior to extubation to receive NIPPV or OX therapy with mask after planned weaning and extubation following institutional protocols. Reintubation required within 48 hours of extubation was considered extubation failure. Results: 97 out of 137 patients were randomized and analyzed. There was no significant difference between two groups in the distribution of underlying disease, PRISM score 12 and 24, arterial blood gases, hemodynamic parameters and duration of invasive MV prior to extubation.The PaO2 at 2 and 6 hours after extubation were significantly higher in patients receiving NIPPV (P value 0.04, 0.01 respectively). Nineteen (19.5%) patients were reintubated within 48 hours of extubation. Thirteen (25%) patients belonged to OX group and 6 (13%) were in NIPPV group (P value 0.12, odds ratio 2.28, 95% CI 0.78-6.61). Commonest reason for reintubation was increased work of breathing. Four patients with failed extubation from OX group were provided rescue NIPPV with success. The total duration of stay in the PICU and hospital were not significantly different in study groups (P value 0.4, 0.4 respectively). Conclusion: Although reintubation were less, our study did not support early elective use of NIPPV immediately after extubation in children.

Background and Objective: The treatment of ventilator-associated pneumonia (VAP) caused by multidrug resistant organisms is challenging even with appropriate intravenous antibiotics. The study was conducted to evaluate the efficacy and safety of nebulised Colistimethate sodium (CS) in the treatment of Gram negative VAP. Methods: For this prospective, interventional, open label, intention-to-treat, randomized trial, 40 consecutive patients were enrolled on the suspicion of VAP. After exclusion, 13 patients in CS nebulisation group and 15 patients in normal saline (NS) nebulisation group were randomized and completed the study. All patients were on systemic antibiotics. The clinical cure was the primary outcome and secondary outcomes included were microbiological cure, durations of mechanical ventilation and stay in PICU and adverse events related with nebulization therapy. Results: Two study groups had comparable clinical characteristics. Clinical and microbiological cures occurred in all patients of CS nebulisation group (100%) but in 11 out of 15 (73.3%) patients in NS nebulisation group (p-0.06). The total duration of mechanical ventilation and PICU stay were not significantly different in two groups. No statistically significant differences were observed with regard to adverse events. Conclusion: Aerosolized CS seems to be safe with no major adverse effects and with no clinical and microbiological benefits. There is need for adequately powered, multicentre study.

Objective: Scanty literature is available regarding continuous renal replacement therapy (CRRT) utility in severe sepsis with multiorgan dysfunction syndrome (MODS) from developing countries. Author unit's experience in pediatric CRRT is described and outcome of early initiation of CRRT with sepsis and MODS is assessed. Materials and Methods: Children aged

There is a need to validate and suggest easy clinical method for diagnosis of ventilator-associated pneumonia (VAP) in developing countries.To validate the use of simplified Clinical Pulmonary Infection Score (CPIS) for the diagnosis of VAP.Prospective study.Pediatric intensive care unit of a tertiary care teaching hospital.30 children receiving mechanical ventilation for more than 48 hours and with simplified CPIS=6.All patients underwent flexible bronchoscopy to obtain bronchoalveolar lavage which was analyzed quantitatively. Colony count = 10(4) cfu/mL was considered reference standard for definite VAP.Of the five variables used for simplified CPIS, only patients temperature (P=0.013) and PaO2/FiO2 ratio were significant (P0.001) to differentiate the presence of definite VAP. Patients with definite VAP (BAL colony count = 10(4) cfu/mL) had CPIS of 8.4 while in no definite VAP group it was 6.4 (P=0.007). CPIS of 8 was found to have sensitivity of 80%, specificity 80%, PPV 86.9%, NPV 70.5% and accuracy 80%. The area under Receiver operating characteristic curve of CPIS against reference standard was 0.81± 0.069 (P=0.001).Simplified CPIS is useful in patients on mechanical ventilation to diagnose ventilator-associated pneumonia.

Objectives: Thrombocytopenia is commonly observed in critically ill patients. This study was undertaken to evaluate the variation in platelet counts and the risk factors associated with thrombocytopenia and mortality in pediatric intensive care patients. In addition, prognostic value of platelet counts for outcome in pediatric intensive care unit was studied. Study Design: Prospective, observational cohort analysis. Setting: 8- bedded pediatric intensive care unit of a tertiary care teaching hospital. Patients: All consecutively admitted patients (n=138) staying in the pediatric intensive care unit (PICU) for at least 48h over a 7 months period were studied. Measurements and Main Results: Thrombocytopenia was defined as platelet counts < 150.0/nL. Median 1 st day Pediatric Risk of Mortality Score (PRISM) was 5 (range 0-30) and median ICU stay was 4 days (range 2-98 days). Twenty five percent patients had at least one episode of thrombocytopenia during the stay. Twenty percent of these patients had thrombocytopenia on admission and rest (80%) developed it during the PICU stay. Seventy one percent (19) of the patients developed thrombocytopenia by fourth day of admission. Patients with PICU acquired thrombocytopenia had statistically significant lower baseline, nadir and 4th day platelet counts and a significantly higher drop in platelet counts (56% vs. 6% P< 0.001) as compared to non thrombocytopenic patients. PRISM score, long PICU stay, sepsis, coagulopathy, and creatinine levels were significantly associated with occurrence of thrombocytopenia. Patients with thrombocytopenia had higher probability of bleeding (34% vs. 15%, P=0.01). Higher platelet counts on admission were associated with significantly reduced risk of thrombocytopenia (P=0.00) Baseline, nadir and day-4 platelet counts, presence of thrombocytopenia on admission, sepsis, coagulopathy and a higher mean PRISM score on univariate analysis were significantly associated with mortality. Leucopenia or leucocytosis, thrombocytopenia and coagulopathy were found to significantly affect outcome. Drop in platelet counts was found to have slightly higher discriminative value for mortality prediction than PRISM on the ROC curve. The survivors had higher platelet counts throughout the PICU stay and after an initial fall in platelet counts in the PICU showed a significantly higher rise in the platelet counts in the following days than the non-survivors. Conclusions: Thrombocytopenia is common in PICU. Patients requiring cardiopulmonary resuscitation or with circulatory shock, coagulopathy, sepsis and with more severe disease have higher risk of developing thrombocytopenia. Thrombocytopenic patients have a higher risk of bleeding. Drop in platelet counts> 27% and thrombocytopenia were independently related to mortality. Serial measurements of platelet counts are better predictors of pediatric intensive care outcome than one-time values. Any drop in platelet counts even without thrombocytopenia needs an urgent and extensive evaluation.

Objective: To compare the ventilation parameters of conventional, volume-controlled (VC), and pressure-regulated volume-controlled modes in sick children with varying lung disease, the effects of specific mode on ventilation-related complications and patient outcome, and improvement in oxygenation with any specific mode. Design: Retrospective case record analysis. Setting: Seven-bedded tertiary-care pediatric intensive care unit in North India. Patients: Twenty-eight ventilated children admitted from July to December 2000. Intervention: None. Measurements and Main Results: Twenty-eight patients were studied with equal number in VC and pressure-regulated (PR) VC groups. The demographic profile, as well as preventilation and on ventilator blood-gas analysis were comparable in the two groups. Mean airway pressure in PRVC group was 17.5% lower as compared with that in VC group ( P = 0.03). Similarly, preventilation PaO2 (65 ± 17 mmHg), PaO2/FiO2 (121 ± 41 mmHg), and respiratory index (RI) (4.91 ± 2.7) improved significantly (P Conclusion: PRVC ventilation is beneficial and improves oxygenation in initial stages of ventilation.

Mechanical ventilation is a life-saving therapy used in children in PICU. These critically ill children are usually extensively investigated in PICU. Chest radiograph is an irreplaceable investigation in these patients prior to ventilation. AIM: We studied the impact of initial chest radiograph on the final outcome of ventilated children. DESIGN: Retrospective. SETTING: Tertiary care teaching hospital. METHOD: One hundred and forty-one children were included in the study. Initial chest radiograph of all the ventilated children was evaluated and outcome of these children was correlated with the initial radiograph at admission. RESULTS: Abnormal initial radiograph was recorded in 60% (n = 84) ventilated children. Overall mortality in ventilated children was 24% (n = 34). Ventilated children with abnormal initial radiograph had significantly greater mortality (28/84) than those with initial normal chest radiograph (6/57) (P CONCLUSION: Initial chest radiograph at the beginning of ventilation may be useful to predict the outcome of these children

Dengue virus infection can cause a wide spectrum of illness. Thrombocytopenia with concurrent haemoconcentration differentiates dengue haemorrhagic fever from classical dengue fever. Only cases with shock or unstable vitals signs need admission in the pediatric intensive care. The management is essentially supportive and symptomatic. The key to success is frequent monitoring and changing strategies. A rise in hematocrit of 20% along with a continuing drop in platelet count is an important indicator for the onset of shock. Patients in grade I and II should be closely monitored for signs of shock. The management of dengue shock syndrome (grade III and IV) is a medical emergency needing prompt and adequate fluid replacement for the rapid and massive plasma losses through increased capillary permeability. Early and effective replacement of plasma losses with plasma expanders or fluid and electrolyte solutions results in a favourable outcome in most cases. The ideal fluid management should include both cystalloids and colloids (including albumin). Cystalloids are given as boluses as rapidly as possible, and as many as 2 to 3 boluses may be needed in profound shock. Colloidal fluids are indicated in patients with massive plasma leakage and in whom a large volume of cystalloids has been given. Frequent recording of vital signs and determinations of haematocrit are important in evaluating the results of treatment. Apart from correction of electrolyte and metabolic disturbances, oxygen is mandatory in all patients of shock. Some patients develop DIC and need supportive therapy with blood products (blood, FFP and platelet transfusions). Polyserositis, in the form of pleural effusion and ascitis, are common in cases of dengue shock syndrome, and if possible, drainage should be avoided as it can lead to severe hemorrhages and sudden circulatory collapse. The prognosis depends mainly on the early recognition and treatment of shock.

Objectives To compare the available methods for the diagnosis of ventilator-associated pneumonia in intubated pediatric patients and to suggest less costly diagnostic method for developing countries. Design Prospective study. Setting Pediatric intensive care unit of a tertiary care, multidisciplinary teaching hospital located in northern India. Patients All consecutive patients on mechanical ventilation for >48 hrs were evaluated clinically for ventilator-associated pneumonia. Interventions Four diagnostic procedures (tracheal aspiration, blind bronchial sampling, blind bronchoalveolar lavage, and bronchoscopic bronchoalveolar lavage) were performed in the same sequence within 12 hrs of clinical suspicion of ventilator-associated pneumonia. The bacterial density > or =104 colony-forming units/mL in a bronchoscopic bronchoalveolar lavage sample was taken as reference standard. Measurements and main results Thirty patients with 40 episodes of ventilator-associated pneumonia were included in the study. Tracheal aspirate at the cutoff of > or =105 colony-forming units/mL was found to have sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 84%, 77%, 87.5%, 73%, and 80%, respectively. For blind bronchial sampling at > or =104 colony-forming units/mL cutoff, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 88%, 82%, 88%, 83%, and 87%, respectively; the most reliable results were obtained with blind bronchoalveolar lavage at the cutoff of > or =103 cfu/mL (sensitivity 96%, specificity 80%, positive predictive value 88%, negative predictive value 92%, and accuracy 90%). The area under the receiver operating characteristic curve of tracheal aspiration, blind bronchial sampling, and blind bronchoalveolar lavage was 0.87 +/- 0.06, 0.89 +/- 0.06, and 0.89 +/- 0.05, respectively. The cost of balloon-tip pressure catheter used for blind bronchoalveolar lavage was INR 1600.00 (US$40) whereas that for blind bronchial sampling was only INR 35.00 ( Conclusions Blind bronchoalveolar lavage was the most reliable method followed closely by blind bronchial sampling for the diagnosis of ventilator-associated pneumonia. Considering the difference of the cost in the two procedures, blind bronchial sampling may be the preferred method in the pediatric intensive care unit of a developing country.
