Inotropic drugs in acute circulatory failure.

The use of inotropic drugs in patients requiring acute circulatory support is reviewed. A knowledge of their various peripheral effects is essential if the appropriate drug is to be used. The place or pressor amines, digitalis, salbutamol and glucagon in the treatment of patients with poor tissue perfusion is limited. Of the catecholamines, adrenaline causes excessive renal vasoconstriction and peripheral gangrene, noradrenaline increase myocardial work and diminishes peripheral perfusion and isoprenaline distributes blood away from the vital organs, namely: brain, kidneys, heart and mesentery. Dopamine is a useful agent as it enhances renal blood flow in low doses and is not excessively chronotropic. Dobutamine has not yet been shown to have significant advantages over other inotropes and requires further examination.

Continuous tissue pH measurement in critically ill adults with a miniaturised glass electrode.

A continuously reading subcutaneous pH electrode has been developed which gives relatively stable readings when applied to any well perfused part of the body. The results obtained with this electrode have been compared with the actual pH of the arterial blood measured by conventional methods. Thirty patients were studied and one hundred and sixty three observations were made. The correlation coefficient (r) between tissue pH (pHt) and arterial pH (pHa) was 0.76 (P less than 0.01). The response time of the electrode in vitro was less than one minute and, in vivo, stabilization of the recording occurred in less than three minutes. It was found that the discrepancy between pHa and pHt gave a good indication of the adequacy of tissue perfusion.

The assessment of disability in patients on an acute medical ward for elderly people.

The level of independence in self-care was monitored weekly in 212 patients admitted over 6 months to an acute medical ward for elderly people, and documented on discharge using a standard assessment, the Barthel Index. At discharge from the admitting ward, 39% of patients were independent (Barthel score of 20), 36% were mildly dependent (Barthel 15-19), 15% were moderately dependent (Barthel 10-14), 4% severely dependent (Barthel 5-9) and 6% very severely dependent (Barthel 0-4). Approximately 80% were able to transfer, walk, were continent of urine and could wash their top half, but one-third were unable to dress or use the toilet independently. Over half were unable to bath themselves or climb stairs unaided. It is feasible to assess disability in a busy acute service this way. Information can be provided both to community services on discharge of individual patients, and to managers responsible for planning services for elderly people.

Support of first-time mothers in the first three months after birth.

This paper examines the perceptions of first-time mothers of the visits of family members and friends during the first three months post partum. It is a prospective, longitudinal study which uses a multiple method approach. Twenty-four first-time mothers participated in the study. An article concerning computerisation of midwifery services starts on p. 42.
