To evaluate the association between trauma team activation according to well-established protocols and patient survival. ⋯ In our institution, undercalls account for 28% of patients who meet trauma call criteria and in patients with moderately poor probability of survival undercall is associated with decreased survival. Although trauma team activation does not guarantee better survival, better compliance with trauma team activation protocols optimises processes of care and may translate into improved survival.

Perceived self-efficacy is a predictor of behaviour and therefore an important dimension of resuscitation training which may have consequences for patient care. The Advanced Paediatric Life Support (APLS) course makes use of techniques which would be expected to increase self-efficacy. We examined the effect of this course on perceived self-efficacy in respect of resuscitation skills and on the use of these skills. ⋯ The APLS course does have an important effect on perceived self-efficacy but this is not related to an increase in the frequency of use of the skills learned on the course, partly because the opportunity for increased use is lacking. Further work is needed to determine whether the quality of those skills is improved by the course.

A young pregnant woman (32nd week of gestation) presented with acute chest pain due to right coronary artery dissection (CAD) in a pre-hospital setting. The pre-hospital diagnosis by the ambulance staff of an acute myocardial infarction in the antenatal period based on a 12-lead ECG combined with successful treatment by percutaneous coronary intervention with stenting is novel.

We aimed (1) to determine the relationship between arterial base excess (BE) immediately after the restoration of spontaneous circulation (ROSC) and duration of cardiopulmonary resuscitation (CPR) and (2) to ascertain the value of admission BE data as a predictor of mortality in patients resuscitated from cardiac arrest (CA). ⋯ (1) BE immediately after ROSC was well correlated with CPR duration. (2) BE could thus distinguish survivors from non-survivors; however, it was not found to be an independent predictor for mortality in resuscitated CA patients.

We have used hypothermic retrograde jugular venous flush to cool the brain previously and to provide better resuscitation than peripheral cold saline infusion during heatstroke in the rat. The current study was performed to assess the effects of brain cooling further on production of reactive nitrogen species, reactive oxygen species, tumor necrosis factor-alpha, and interleukin-10 in both serum and brain during heatstroke. Rats, under general anaesthesia, were randomized into the following groups and given: (a) 36 degrees C or (b) 4 degrees C saline infusion in the external jugular vein immediately after onset of heatstroke. ⋯ The cerebrovascular dysfunction, the increased levels of nitric oxide metabolites, tumor necrosis factor-alpha, and dihydroxybenzoic acid in both the serum and the hypothalamus, and the increased levels of hypothalamic inducible nitric oxide synthase immunoreactivity occurred during heatstroke were significantly suppressed by brain cooling. Although the serum and hypothalamic interleukin-10 maintained at a negligible level before stress, they were significantly elevated by brain cooling during heatstroke. These findings suggest that brain cooling may resuscitate persons who had heatstroke by decreasing overproduction of reactive nitrogen species, tumor necrosis factor-alpha, reactive oxygen species and cerebrovascular dysfunction, but increasing production of interleukin-10.
