Phrenicotomy in the rat: acute changes in blood gases, pH and body temperature.

Adult male rats were used to compare blood gases, pH and body temperature (Tb) before and after acute bilateral phrenicotomy. Under anaesthesia a femoral artery was catheterised and ties were placed round the phrenic nerves of seven rats (PNX group), while in five rats the ties were placed in the vicinity of the phrenic nerves (SHAM group). Twenty-four hours after surgery arterial blood samples were collected during quiet wakefulness (QW) and grooming (G), before and 1 h after the ties were pulled, and analysed for PO2, PCO2 and pH. No changes were detected in the SHAM samples taken before and after the ties were pulled. In the PNX group a significant decrease in Tb occurred (QW, 0.6 degrees C; G, 1.5 degrees C). Following PNX PaO2 decreased by 11.2 mmHg (QW) and 10.0 mmHg (G); PaCO2 increased by 2.6 mmHg (QW) and 2.4 mmHg (G) and pH fell by 0.04 (QW) and 0.03 (G). All changes except in PaCO2 (QW) were significant. It is concluded that the changes in Tb, blood gases and pH which follow phrenicotomy in the rat are due to an increase in dead space ventilation (VD) and a small reduction in alveolar ventilation (VA) associated with a faster, shallower pattern of breathing.

Child

The elderly isolate.

Isolates do not differ from other elderly people in respect of their medical illnesses. They do differ in their ability to cope. When well, they cope better than do non-isolates. However, when incapacitated by sickness, they require supportive help services more often and if these are lacking, are more likely to be admitted to a nursing home. Loneliness, alcohol dependence and depression are more often problems of the isolate.

Aged

The assessment of need for support services as seen by general practitioners and a geriatric population.

The majority of doctors accepted the need for involvement in the management of patients with behavioural, family and welfare type problems. The health team concept was seen as desirable by a majority of respondents, though they appeared to feel that it made no great difference if the team members functioned from a health centre or were located in different sites. They were not so well informed as to the availability of supportive welfare services as they were of medical services. Of the elderly people interviewed, most had received medical care in the previous two months, and chiropody was the commonest supportive service used. About half were assessed as having at least one disability affecting their functional capacity, and a significant number were thought to be receiving inadequate care. There was an obvious need for home help services, which were in limited supply.

Aged

A department of personal and family medicine.

There has been increasing, worldwide dissatisfaction with the relevance of medical education to health care. Recently, a special task group set up by The Royal Australian College of General Practitioners made a study of how a department of personal and family medicine could participate in the education of the medical student. The task was to present first steps in a research and development programme for education of health personnel to work in and near the family setting. Two academics, two nurse educators, two general practitioners, one specialist surgeon involved in medical education and a fifth-year medical student made up the group. It worked at the task during a six-day live-in teaching and leadership seminar at Leura, New South Wales, in February, 1973.
