Resuscitation

To assess the prevalence and implementation of 'do not resuscitate' orders, nowadays called 'do not attempt resuscitation' (DNAR) orders and living wills among patients suffering in-hospital cardiac arrest (CA) in whom cardiopulmonary resuscitation was not initiated. ⋯ Most patients who suffered in-hospital CA without resuscitation had a DNAR order, and, for those who did not, terminal disease and medical futility were evident in most cases. Living wills were uncommon, but they appeared to have had some impact on treatment.

Comparative Study
Comparison of ease of use of three automated external defibrillators by untrained lay people.
The use of automated external defibrillators (AED) by lay people has the potential to markedly increase survival from community cardiac arrest. Wider public use of AEDs requires units that can be operated safely and effectively by people with minimal or no training. This study compares the use of three AEDs by untrained lay people regarding ease-of-use, safety, pad positioning and time to defibrillation. 24 subjects with no prior exposure to the use of AEDs were asked to perform simulated defibrillation on a manikin using three defibrillators: Zoll AEDPlus, Medtronic Physio-Control LifePak CR Plus and Philips/Laerdal HeartStart OnSite Defibrillator. ⋯ The majority of subjects safely and effectively delivered defibrillating shocks without any prior training and within quite acceptable times. Untrained subjects find the Physio-Control and Laerdal Defibrillator easier to use than the Zoll device. Features of AED design that improved ease of use are discussed.

Accidental hypothermia is a common companion of trauma/haemorrhage, and several clinical studies have identified reduced body temperature as an independent risk predisposing to increased morbidity and mortality. Accordingly, the majority of trauma care guidelines prescribe early and aggressive rewarming of hypothermic patients. Enzyme reactions are generally downregulated at temperatures below 37 degrees C, including most of those responsible for the inflammatory response. ⋯ The pro-inflammatory cytokines TNF-alpha and IL-6, the anti-inflammatory cytokine IL-10, the organ markers alanine aminotransferase, alpha-glutathione S-transferase and creatinine, as well as organ injury scores were equal in both groups. Three rewarmed rats died prematurely, versus one hypothermic animal. In conclusion, the results suggest that during the early stages after haemorrhagic shock, rapid rewarming from mild hypothermia may have unfavourable effects both on basic haemodynamic variables, and on the internal inflammatory environment of cells and tissues.

Guidelines for the management of suspected spinal injury patients from the scene of their accident to the emergency department were published in September 1998. This study was commissioned on behalf of the Faculty of Pre-hospital Care at the Royal College of Surgeons of Edinburgh, to examine the handling of patients on spinal boards on arrival in the emergency department. ⋯ It is suggested that as the spine board is such a widely used piece of equipment, there should be some guidelines to standardise its use at the emergency department interface with pre-hospital care. We recommend that spinal board removal should be part of the completion of the primary survey.
