Background: In patients up to the age of 40 years old severe trauma is the most frequent cause of death in Germany. According to the current S3 guidelines on treatment of polytrauma and the severely injured, since 2011 the presence of a shock room coordinator should be considered, who can improve the survival of patients by optimized treatment quality and times. The aim of the present study was to analyze various parameters of shock room treatment for polytraumatized patients before and after implementation of a shock room coordinator for treatment of polytrauma., Material and Methods: To ensure an adequate period of time between the implementation of the shock room coordinator in 2011, data from 2009 and 2012 were included for comparative purposes. All scanned protocols of shock room treatment in the period from 1 January 2009 to 31 December 2009 and from 1 January 2012 to 31 December 2012 were inspected and evaluated., Results: In total 213 shock room treatments from 2009 and 420 from 2012 were included. The mean number of shock room treatments in 2009 was 17.8 per month and in 2012 the mean number was 35 per month. The mean number of shock room treatments was nearly doubled in comparison (p < 0.001). The mean time for shock room treatment in 2009 was 74.8 min and in 2012 the mean time was 69 min and was therefore reduced by 5.8 min (p = 0.56)., Conclusion: The treatment of polytraumatized patients in the presence of a shock room coordinator and after implementation of the standard operating procedure (SOP) was neither statistically nor clinically relevantly shortened.

Background: Correct positioning of a central venous catheter (CVC) tip in pediatric patients is very important. Malpositioning may lead to direct complications, such as arrhythmia and increase the risk of thrombosis, infections, valve failures or pericardial tamponade., Objective: The aim of this review was to identify and summarize published formulae for the correct positioning of the CVC tip in children and to discuss the benefits of these formulae for the daily routine., Material and Methods: A systematic and standardized search in Medline and PubMed was performed to identify published formulae. Formulae for insertion depth of the CVC tip over the right internal jugular vein are discussed. The keywords "pediatric" or "pediatric", "children", "central venous catheter", "CVC", "central venous", "length", "insertion", "optimal", "formula", "depth", "correct position" and "right position", "internal jugular vein" were used to identify the formulae., Results: A total of 854 publications were found and 127 publications were analyzed. The publications were subsequently assessed and classified independently by a specialist in anesthesiology and a specialist in pediatrics. A total of six publications described different body height-based formulae for calculation of a CVC insertion depth. No prospective evaluation of these formulae was performed to show if it is possible to place a CVC tip at the optimal position., Conclusion: The benefit of a formula for daily practice is very limited due to the problem of choosing the right insertion point. The recommended insertion depth should be considered as an indicator and a verification of the CVC tip position should be done using an imaging technique.

Background: Central venous cannulation is widely used in neonatal critical care. Pericardial tamponade caused by vessel wall perforation can occur if the catheter tip induces extravasation at the level of the pericardium., Objective: To investigate the level of the superior pericardial reflection in stillborn babies., Materials and Methods: We dissected 20 bodies (11 female, mean gestational age 33 6/7 weeks, range 25-43 weeks), with careful opening of the thoracic area. After injecting contrast medium into the pericardial sac, we introduced a catheter through the right internal jugular vein. We then took radiographs to analyse the relationship between visual osseous landmarks and the pericardium., Results: Mean distance between the pericardial reflection at its upper end and the first thoracic vertebra was 1.3 cm (standard deviation [SD]: 0.3 cm) and did not extend over the 3rd intercostal space. The mean distance from the entry of the superior vena cava into the pericardial sac and the 1st thoracic vertebra was 2.3 cm (SD: 0.5)., Conclusion: The upper end of the pericardial reflection in neonates at autopsy lies below the middle of the 3rd thoracic vertebra. The tip of an upper inserted catheter should not extend below the level of the 3rd intercostal space.
