A community training scheme in cardiopulmonary resuscitation.

Community instruction in basic life support and resuscitation techniques has been offered in Brighton Health District since 1978. Classes are held frequently for the general public and businesses, schools, and other organisations. First aid care for unconscious patients, the treatment of respiratory obstruction or failure, and the recognition and management of cardiac arrest is taught in a single two hour session. Over 20 000 people have been taught, up to 40 at a time in multiple groups of six to eight, by lay instructors usually supervised by ambulancemen trained to "paramedic" standards. Fifty four incidents have been reported to us in which techniques learnt in the classes have been implemented. Five patients recovered after first aid support but subsequently did not seek medical treatment. Of the 34 patients reviewed in hospital, at least 20 survived to be discharged. We believe that intervention may have been life saving in 16 instances. The benefit of cardiopulmonary resuscitation for victims who may have been asystolic is, however, difficult to quantify because the outcome without intervention cannot be predicted accurately. Community training in basic life support should be considered in association with ambulances equipped for resuscitation and hospital intensive care and cardiac care units as an integrated service for the victims of sudden circulatory or respiratory emergencies. The results achieved so far in Brighton and in other more advanced schemes, particularly in the United States of America, may encourage other health authorities to adopt similar programmes.     

Hypothalamic neurones in culture. II. A progress report.

Cultures of the hypothalamic supraoptic nucleus area were prepared from 1--10 day old rats by means of the roller-tube technique. After 3 weeks in vitro large nerve cells with long, thin and repeatedly branching axons could be observed. In silver-stained co-cultures of hypothalamic and hypophysial tissue, fibers were seen to bridge the gap between the adjacent explants. Intracellular current injection into the large nerve cells elicited single or repetitive action potentials. Two types of spontaneous discharge patterns were observed. The majority of cells fired randomly and the remainder displayed a phasic dicharge pattern. Simultaneous recordings from 2 cells disclosed that pairs of phasic cells had a tendency to fire in synchronous bursts.     

A new technique in nasal-tip reduction surgery.

This article presents a technique for the reduction of the overprojected nasal tip with a proportional reduction of the nostril-margin circumference. To achieve these reductions, a modified open rhinoplasty technique is used, which is unique in that it involves the total transection of the columella through the medial crura of the alar cartilage. The alar cartilage is raised with the flap.The technique was first developed and introduced by the senior author (R.A.S.) 25 years ago and has since been refined through the execution of several thousand rhinoplasties. The results continue to be consistent and pleasing from both the patients' and the surgeon's points of view.
