UK hospitals have been instructed to ensure that all staff understand the institution's resuscitation policy. Using a questionnaire, we determined the level of knowledge about the hospital's 'do not attempt resuscitation' (DNAR) policy amongst a range of staff. Six hundred and seventy-seven questionnaires were returned. 91.4% of responders did not know the correct overall percentage survival to hospital discharge following an in-hospital cardiac arrest. 19.3% of doctors, 10.6% of nurses, and 8.9% of health care support workers (HCSW) gave answers in the correct range (i.e., 15-25%). ⋯ There was inconsistency about what information staff felt should be included in DNAR documentation and what, if any, continuing care should be given to patients who are not for resuscitation. Our study demonstrates that there is room for improvement in the awareness of staff about the DNAR process. The local DNAR policy is being reviewed to ensure that its messages are clear and a specific DNAR educational programme has been commenced.

To assess the experience, knowledge and attitudes of local primary health-care doctors towards resuscitation in out-of-hospital cardiac arrest. ⋯ Primary care physicians do see themselves as having an important role in resuscitation. We propose a local initiative to equip, educate and encourage defibrillation by GPs in our community.

Emergency medical services in Zimbabwe are of a very variable standard, and exist in many forms: *Reasonably well-developed urban emergency medical services systems mixed with very poorly resourced and under-developed rural services. *Very high patient workloads, with severely ill medical patients and a large proportion of major trauma and multiple-casualty situations (public safety is given a low priority, and public transport is poorly regulated). *Long emergency response times and patient transport distances. *Somewhat under resourced and under developed emergency departments, with large numbers of critically ill acute patients, as well as many non-emergency/chronic patients who have no other access to appropriate health care. This paper provides a description of the development of ambulance services and acute health care in Zimbabwe, and outline the current demands on the system. Particular reference is made to the City of Harare Ambulance Service, which is considered to be the most developed of the local authority services.

Comparative Study
Effect of hypothermia on transthoracic defibrillation in a swine model.
Induced hypothermia (H) appears a promising intervention to protect the heart and brain after resuscitation from cardiac arrest. However, the influence of H on transthoracic defibrillation energy requirements is not well documented. ⋯ Severe H facilitated transthoracic defibrillation in this swine model. Since impedance rose and current fell during H, the improved shock success must be due to a hypothermia-induced change in the mechanical or electrophysiologic properties of the myocardium. Moderate hypothermia did not alter the energy requirement for defibrillation.
