Resuscitation

Severe neurological deficits are common characteristics of patients surviving cardiopulmonary resuscitation (CPR) or isolated severe head trauma (SHT). For comparative evaluation of underlying pathomechanisms, 22 patients with out-of-hospital cardiac arrest and successful CPR as well as 10 patients with SHT were included in our prospective study. Circulating S-100B was determined as an indicator of cellular brain damage. ⋯ Both clinical entities seem to be associated with early transient cellular brain damage as shown by prolonged rapidly increasing and subsequent fall in S-100B serum levels. In contrast, the prolonged elevation of circulating IL-8, sE-selectin and PMN-elastase may indicate a very similar systemic inflammatory response by endothelial cells and neutrophils initiated by ischaemia and reperfusion injury in both conditions. Further studies should be carried out to determine the cause and the prognostic value of these biochemical parameters in relation to long-term neurological outcome.

patients with cardiac arrest have a high mortality and the long-term outcome is doubtful. The prognosis is mainly dependent on clinical parameters. S-100 and neurone specific enolase (NSE) are established biochemical markers of central nervous system (CNS) injury. The purpose of this study was to validate the use of serum determinations of S-100 and NSE with neurological investigations in regard to brain damage and long-term outcome after cardiac arrest. ⋯ the serum levels of S-100 and NSE increased after cardiac arrest due to the anoxic brain damage. The determination of S-100 and NSE can be used as an adjunct to predict long-term outcome after cardiac arrest.

We evaluated the type and severity of injuries and the possible influence of a helicopter staffed by a physician on the outcome of 71 consecutive occupants ejected from a four-wheel vehicle ejected occupants who were cared for by the Swiss Air Rescue Helicopter team from January 1994 to February 1999. The investigation and the data collection were planned prospectively. The following data were collected for each patient ejected from a four wheel vehicle: (1) demographic information; (2) type of injury; (3) vital signs on scene, in flight and at hospital; (4) hospital diagnosis; (5) injury severity score; (6) secondary transfer; (7) length of stay in hospital and on intensive care; and (8) outcome at hospital discharge. ⋯ In conclusion, ejection from a four-wheel vehicle causes more severe injuries and requires a high number of advanced life support manoeuvres. Based on the mechanism of injury alone, patients ejected from four-wheel vehicles should automatically receive a response from the best available pre-hospital team. In our system, this means the dispatch of a physician staffed helicopter.

To determine whether the introduction of the Medical Emergency Team (MET) system designed to provide immediate help for seriously ill patients: (i) changed the pattern of ICU patient transfers from the wards; and (ii) improved hospital survival rates. ⋯ More information is needed to demonstrate that the MET system improves patient survival. The study also highlights the importance of taking proactive measures, which should include providing in-service education on the benefits of early identification and treatment of patients who are at risk of acute deterioration, raising awareness and changing attitudes in hospitals when introducing system such as the MET.
