During the years 1986 to 1990, an increasing number of cases of acute carbon monoxide (CO) poisoning were encountered in the Emergency Department Hacettepe University Hospital in Ankara, Turkey. Between January 1 and March 31, 1991, all the patients presenting with complaints compatible with CO poisoning were evaluated; the diagnosis was confirmed in 55 of the 5795 people who attended the Emergency Department during this period. In all cases the source of CO intoxication was determined. ⋯ One of them was discharged from the hospital with mild cerebral disability. Another patient developed an acute myocardial infarction. In all the cases in this series, the source of CO poisoning was identified as improper combustion of recently marketed steam coal in inadequately ventilated bucket stoves.

This study was initiated to identify the incidence, risk factors and outcome predictors of patients admitted to hospital in the Netherlands because of accidental hypothermia. Information about these patients was available for study through the National Health Care Data Bank. Between 1987 and 1990, 612 accidental hypothermic patients were admitted: 185 hypothermic patients also suffered from submersion (HYPSUBS), but this was not the case in the remaining 427 patients (HYPNOTSUBS). ⋯ Almost half of the HYPNOTSUBS non-survivors died after more than 2 days. Because body temperature will have returned to normal by then, this must be the result of late complications. Most HYPSUB non-survivors died during the first 2 days, probably as a direct result of the submersion injury.

Hypothermia is a frequent event in trauma patients and appears to be related to post-traumatic organ dysfunction, although in elective surgery hypothermia is known to prevent ischaemia reperfusion injury. Retrospectively we have analysed data from 641 trauma patients treated in our institution between 1988 and 1993. On admission to hospital the core temperature (cT) was > 34 degrees] C in the majority (64%) of patients, followed by 23.6% with a cT < 34 degrees C and 12.4% with a cT < 32 degrees C. ⋯ It also showed that hypothermia is not an independent prognostic factor for post-traumatic mortality. The different effect of hypothermia in trauma compared with elective surgery may be due to a lack of energy-storing phosphates like adenosine triphosphate (ATP). Further current investigations will identify the role of ATP in trauma-related hypothermia.

Multimodality evoked potentials (EPs), linear electroencephalograms and Glasgow Coma Scale (GCS) scores were recorded within 24 h of cardiac arrest in 62 patients who were comatose following cardiopulmonary resuscitation. The cardiac arrest had a cardiac cause in 35 patients and a non-cardiac cause in 27 patients. The Glasgow Outcome Scale (GOS) scores were established 6 months after resuscitation. ⋯ However, while all patients who regained consciousness had normal EPs, not all patients in whom EPs were recordable survived. The GCS score showed a higher sensitivity and correlation with GOS score than EPs, but it was associated with a high percentage of false positive results, and its specificity was only 67%. The combination of the GCS score with EPs may be a promising strategy to counterbalance the respective limits of these methods and to reduce the loss of information due to sedation and myorelaxation, which impede clinical examination but not EP results.
