To assess the effect of a Medical Emergency Team (MET) service on patient mortality in the 4 years since its introduction into a teaching hospital. ⋯ Introduction of an Intensive Care-based MET in a university teaching hospital was associated with a fluctuating reduction in post-operative surgical mortality which was already apparent during the education phase, but a sustained increase in the mortality of medical patients which was similarly already apparent during the education phase. The differential effects on mortality may relate to differences in the degree of disease complexity and reversibility between medical and surgical patients.

Perimortem caesarean section is very rare, mostly resulting in high mortality of mother and/or fetus. We report a case of successful resuscitation of both mother and newborn following maternal cardiac arrest prior to delivery. Postoperative outcome was complicated by severe bleeding and coagulopathy following fibrinolysis and subcapsular hepatic haematoma. We consider a fast reaction time based on a special in-hospital emergency team for immediate caesarean section and an aggressive management of coagulopathy as major factors that led to both patients recovery without neurological sequelae.

To test our hypothesis that the hemoglobin based oxygen carrier HBOC-201 would have similar or superior efficacy to 6% hetastarch (HEX) as a pre-hospital 'bridging' fluid for hemorrhagic shock when delay to definitive medical care is prolonged to 24h. ⋯ HBOC-201 restored hemodynamics, maintained tissue oxygenation, and decreased blood transfusions in comparison to HEX in severe controlled HS with 24h delay to simulated hospital care. These results support the potential use of HBOC-201 as a bridging resuscitation fluid for HS.

Advanced life support (ALS) in a cardiac arrest is usually performed by a team consisting of three people. The medical team of a Helicopter Emergency Medical Service (HEMS) often consists of two rescuers only. Due to that reason an algorithm was developed to provide ALS with two people. During the initial phase the rescuer in the over-the-head position provides one man CPR while the second rescuer prepares all advanced measures. When all preparations are complete both rescuers are able to provide ALS. ⋯ We proved the feasibility of the algorithm in a manikin setting. Further observations have to prove the algorithm in real CPR situations.

Conventional biphasic truncated exponential (BTE) waveforms have been studied extensively but less is known about "chopping modulated" BTE shocks. Previous studies comparing chopped and unchopped waveforms have found conflicting results. This study compared the defibrillation thresholds (DFTs) of a variety of chopped and unchopped BTE waveforms. ⋯ When treating swine with short-duration VF, chopped waveforms require more energy to defibrillate than unchopped waveforms. More study is required to assess the performance of chopped waveforms when treating cardiac arrest patients.
