The study evaluates the knowledge of first aid in mountaineerers who climb routes of moderate difficulty in the western Alps. Additionally the mountaineer's ability to assess their own knowledge was investigated. An analysis of the mountain accidents in the same area showed the real need for knowledge. ⋯ First aid education of mountaineers must be improved. Adequate education should take into account the specific demands of alpine emergencies.

Current adult basic cardiopulmonary resuscitation (CPR) guidelines recommend a 2:15 ventilation:compression ratio, while the optimal ratio is unknown. This study was designed to compare arterial and mixed venous blood gas changes and cerebral circulation and oxygen delivery with ventilation:compression ratios of 2:15, 2:50 and 5:50 in a model of basic CPR. Ventricular fibrillation (VF) was induced in 12 anaesthetised pigs, and satisfactory recordings were obtained from 9 of them. ⋯ In parallel the central venous oxygenation, which gives some indication of tissue oxygenation, was higher for the ratio of 2:15 than for both 5:50 and 2:50. As the compressions were done with a mechanical device with only 2-3 s pauses per ventilation, the data cannot be extrapolated to laypersons who have great variations in quality of CPR. However, it might seem reasonable to suggest that basic CPR by professionals should continue with ratio of 2:15 at present if it can be shown that similar brief pauses for ventilation can be achieved in clinical practice.

Case Reports
Gas gangrene pyaemia with myocardial abscess formation--fatal outcome from a rare infection nowadays.
We report a case of sudden death after gas gangrene. A 67-year-old male patient with diabetes mellitus and chronic renal failure (on haemodialysis three times a week) presented in the surgical emergency department with a severe swelling and crepitation in the right groin. No signs of trauma were present-except for a well-healed, 1-year-old scar after femoro-popliteal bypass surgery. ⋯ Abscess formation was found in the myocardium. Clostridial gas gangrene is a rare clinical condition. Unless immediate diagnosis and adequate therapy measures are taken, the outcome and chances for survival are poor as demonstrated by this case.

A total of 494 participants who were scheduled to take Baskent University's basic life support (BLS) training programme in 2001-02 were asked to complete a 25-item questionnaire prior to the course. The questionnaire investigated the demographic characteristics of the subjects, their knowledge of the theoretical and practical aspects of BLS, and personal experience and attitudes related to BLS. The 'non-medical group' included 179 laypersons, and the 'medical group' was composed of medical students (n=220), residents (n=69) and clinical nurses (n=26). ⋯ Compared to the other participants, individuals with previous emergency experience, and those who had previous BLS training answered significantly more of the theoretical questions correctly. However, neither of these groups performed significantly better than the other participants in the practical questions (P>0.05 for both comparisons). Based on our findings, we recommend that BLS training for medical undergraduates, other medical personnel and laypersons be improved and standardized throughout Turkey.
