Difficult airway situations both expected and unexpected, present major challenges to every anesthesiologist, especially in pediatric anesthesia. However, the integration of extraglottic airway devices, such as the laryngeal mask, into the algorithm of difficult airways has improved the handling of difficult airway situations. A device for establishing a supraglottic airway, the laryngeal tube (LT), was introduced in 1999. The LT is an extraglottic airway designed to secure a patent airway during either spontaneous breathing or controlled ventilation. The design of the device has been revised several times and a further development is the LTS II/LTS-D, which provides an additional channel for the insertion of a gastric drain tube. This article reports on the successful use of the LTS II in 12 children aged from 2 days to 6 years when endotracheal intubation, alternative mask or laryngeal mask ventilation failed. Use of the LTS II was associated with a high level of success, securing the airway when other techniques had failed. The potential advantage of the LTS II over the standard LT is an additional suction port, which allows gastric tube placement and can be used as an indirect indicator of correct placement. With a modified insertion technique using an Esmarch manoeuvre, placement was simple and fast to perform. In emergency situations when direct laryngoscopy fails or is too time-consuming the LTS II tube is recommended as an alternative device to secure the airway. As with all extraglottic airway devices, familiarity and clinical experience with the respective device and the corresponding insertion technique are essential for safe and successful use, especially in emergency situations.

Background: The difficult airway remains a challenge especially in emergencies.Materials and Methods: The use of laryngeal tube suction in 8 cases involving difficult airways in emergencies was reviewed.Results: Use of the laryngeal tube was successful in all cases to bridge patients until a secure airway was established; insertions were successful at the first attempt and classified as easy. In 6 out of 8 patients a secure airway was established by cricothyreotomy or by surgical tracheotomy while using the laryngeal tube for oxygenation and ventilation of the patient.Conclusion: The laryngeal tube allows rapid oxygenation in emergency patients with a difficult airway until a secure airway can be established. In cases of potentially life saving operations successful ventilation via the laryngeal tube might allow the priority of establishing a secure airway to be deferred. [ABSTRACT FROM AUTHOR]

Background: Healthcare personnel may be faced with different degrees of violence and aggression, particularly concerning preclinical care. However, systematic data with respect to the frequency and type of violence in emergency medicine in Germany has not been researched.Methods and Objectives: At an anesthesiology congress, an anonymous survey was distributed about the different kinds and extent of violent acts that the participants had experienced during their work in emergency medicine. Moreover, the participants' subjective feelings toward professional and personal safety when handling emergency cases were explored.Results: Every fourth participant in the survey (25.2 %) had experienced occupational physical violence within the last 12 months. Verbal harassment or insults within the last twelve months were reported by 58.2 % of the participants. While 80 % of the participants feel "entirely" or "mostly" safe with regard to the professional aspect of their occupation, personal safety was considered "entirely" in only 9.3 % and "mostly" in 46.4 % of the cases. Nearly every third participant (31.8 %) feels only "partially" safe and every eighth participant feels "rather not" or "not at all" safe during emergency medicine missions. Men appreciate their expertise as well as their personal safety more so than women (p < 0.001).Conclusion: Aggression and violence towards healthcare personnel in emergency medicine occur on a regular basis in the German healthcare system. Little research has been conducted in this area, so the issue has not yet been perceived as a relevant problem. Appropriate training for healthcare personnel in emergency medicine should be targeted at developing the skills needed when encountered with aggression and occupational violence.

Background: In the year 2000 a working group of the German Interdisciplinary Association for Intensive Care Medicine (DIVI) defined a core data set on quality assurance for the first time. In the following years the participating intensive care units sent data to the registry on a voluntary basis and received an annual report on benchmarking data. Alterations in the quality in the field of intensive care medicine have so far only been published to a very low extent.Aim: This study analyzed the core date set of the DIVI between 2000 and 2010 in respect to changes in disease severity using the simplified acute physiology score (SAPS II), the sequential organ failure assessment (SOFA), the need for therapeutic interventions with the therapeutic intervention scoring system (TISS 28) and intensive care unit (ICU) mortality.Material and Methods: Inclusion criteria were participation in the registry for at least 4 years, SAPS II, SOFA, TISS28 scores available and data on ICU discharge. A standardized mortality rate (SMR) was calculated for each year.Results: The mean SAPS II score including 94,398 patients increased by 0.23 points/year with a standard error (SE) of 0.02 to 26.9 ± 12 points (p < 0.001). Similarly, the SOFA score on admission to the ICU increased by 0.14 points/year (SE 0.04) to 3.4 ± 2.7 points (p < 0.001), the proportion of patients with a two organ failure doubled to 7.1 % and the number of patients dependent on ventilation increased by 13.6 % to 59.8 %. The mean time on ventilation increased by 0.17 ventilator days/year (SE 0.01, p < 0.001) to 3.1 ± 7.5 days/patient. The mean number of therapeutic interventions increased by 8.7 % to 26.3 ± 8.3 TISS 28 points/day. The mean length of stay on the ICU (4.3 ± 8 days) and the age of the patients (63.2 ± 17.0 years) remained unchanged. The readmission rate showed no significant changes between the years 2004 and 2010. The readmission rate to the ICU within 48 h after primary discharge was 3.1 % with a 95 % confidence interval (CI) of 3.0-3.3 in contrast to 1.5 % (95 % CI 1.4-1.6) for readmission to the ICU after 48 h. The length of stay in hospital before admission to the ICU decreased for patients with scheduled surgery (6.3 ± 9.7 days vs. 4.2 ± 6.9 days), increased slightly for patients with medically indicated admission to the ICU (2.4 ± 8.2 days 3.1 ± 8.6 days) and remained unchanged for patients with unscheduled admission to the ICU after surgery (4.1 ± 8.6 days). The SMR decreased between 2000 and 2004 from 0.97 to 0.72 and increased again thereafter to 0.99 (ICU mortality 8.5 %).Conclusion: The severity of disease on admission to the ICU, the proportion of patients on ventilation and the workload of therapeutic interventions increased between 2000 and 2010 in German ICUs but the length of stay of patients in the ICU remained unchanged. The SMR decreased until 2005 and increased thereafter to return to the initial values. The overall ICU mortality was low compared to international data. [ABSTRACT FROM AUTHOR]

Background: Trauma care personnel are at risk of occupational exposure to blood-borne pathogens. Little is known regarding compliance with standard precautions or occupational exposure to blood and body fluids among multiple trauma care personnel in Germany., Aim: Compliance rates of multiple trauma care personnel in applying standard precautions, knowledge about transmission risks of blood-borne pathogens, perceived risks of acquiring hepatitis B, hepatitis C and human immunodeficiency virus (HIV) and the personal attitude towards testing of the index patient for blood-borne pathogens after a needlestick injury were evaluated., Material and Methods: In the context of an advanced multiple trauma training an anonymous questionnaire was administered to the participants., Results: Almost half of the interviewees had sustained a needlestick injury within the last 12 months. Approximately three quarters of the participants were concerned about the risk of HIV and hepatitis. Trauma care personnel had insufficient knowledge of the risk of blood-borne pathogens, overestimated the risk of hepatitis C infection and underused standard precautionary measures. Although there was excellent compliance for using gloves, there was poor compliance in using double gloves (26.4 %), eye protectors (19.7 %) and face masks (15.8 %). The overwhelming majority of multiple trauma care personnel believed it is appropriate to test an index patient for blood-borne pathogens following a needlestick injury., Conclusion: The process of treatment in prehospital settings is less predictable than in other settings in which invasive procedures are performed. Periodic training and awareness programs for trauma care personnel are required to increase the knowledge of occupational infections and the compliance with standard precautions. The legal and ethical aspects of testing an index patient for blood-borne pathogens after a needlestick injury of a healthcare worker have to be clarified in Germany.

Acute renal failure is a common complication in intensive care medicine. While the incidence of acute renal failure increases, mortality still remains at a high level. In Europe continuous renal replacement therapy (CRRT) has become the standard treatment for acute renal failure. Continuous renal replacement therapy has the advantage of achieving a more stable haemodynamic situation and an easier volume management compared to intermittent haemodialysis (IHD). Until now there has been no evidence to suggest that either classical IHD or CRRT is superior in reducing mortality. Using CRRT in patients with acute renal failure, an ultrafiltration rate adjusted to the patient's bodyweight at 35 ml/kg x h is recommended. A new approach in renal replacement therapy is the slow extended daily dialysis (SLEDD), which combines the advantages of CRRT and IHD. First results are promising, but further investigations are needed to show whether outcome can be improved. A final evidence-based recommendation on the dosing of CRRT or a definitive answer to the question whether daily IHD is better than CRRT, can probably only be possible after two running multicentre studies, the VA/NIH Acute Renal Failure Trial Network (ATN) study and the Augmented Versus Normal Renal Replacement Therapy in Severe Acute Renal Failure Study (ANZICS 2005) Australia and New Zealand Intensive Care Group.

Background: We compared the ease of viewing the glottis under direct vision during conventional laryngoscopy with the quality of indirectly viewing on a monitor during laryngoscopy with a Macintosh videolaryngoscope in a multicenter study., Patients and Methods: After ethical approval and written informed consent of 300 patients with no anticipated difficult airway, conventional laryngoscopy with a Macintosh videolaryngoscopy blade was performed and the quality of the view of the glottis was assessed and documented according to the Cormack and Lehane scoring system as modified by Yentis and Lee. Subsequently, the indirect viewing conditions on the monitor were documented without changing the position of the blade. Differences between both distributions were analyzed using the Bland-Altman Test., Results: Videolaryngoscopy improved the laryngoscopy score by 1 grade in 72 cases, by 2 grades in 17 cases and by 3 grades in 2 cases. A relevant improvement (from grades III/IV to II) was found in 28 patients. Viewing conditions worsened in 3 cases by 1 grade, in 4 cases by 2 grades and in 3 cases by 3 grades. A statistical analysis of the data gave a bias of 0.31 and an SD bias of 0.77.The 95% confidence interval of the distribution ranged from -1.12 to 1.81., Conclusion: Videolaryngoscopy can lead to better viewing conditions but in rare cases it may result in worse viewing conditions.
