The place of pain in human experience.

In this last of our selection of papers from the London Medical Group Conference on Pain, Gilbert Lewis, through his experiences of living in New Guinea describes to us the various rites, rituals and uses of pain in societies other than our own. He outlines, by example, how what often seems the natural behaviour to us for helping a sufferer in fact, can make matters far worse for other peoples. Although different societies approach the problem of pain from many routes the aim of all is to relieve pain for the sufferers. If the sufferer says he feels relief then that is surely what counts.

Haemodynamic effects of salbutamol and nitroprusside after cardiac surgery.

The haemodynamic effects of a continuous intravenous infusion of salbutamol (15 to 30 microgram/min) and nitroprusside (50 to 100 microgram/min) were compared in 9 patients after cardiac surgical operations. The mean falls in left atrial pressure and systemic vascular resistance were similar with the two drugs but salbutamol caused a greater increase in heart rate, maximum acceleration of aortic blood flow, and maximum rate of change of left ventricular power. Because these differences would cause greater myocardial oxygen consumption with salbutamol and because the infusion of salbutamol is less easily controlled, nitroprusside is the preferred drug after cardiac operations.

Electromyography before and after surgery for hip deformity in children with cerebral palsy. A comparison of clinical and electromyographic findings.

Twenty-three ambulatory children with spastic diplegic cerebral palsy were evaluated clinically and by electromyography before and after hip-muscle surgery. The stretch tests originally designed to distinguish specific muscle tightness and spasticity were found to be non-specific when tested by electromyography. Ambulatory electromyograms using needle electrodes and telemetry generally showed decreased activity in the released muscles and, on occasion, changes in activity in muscles not operated on. These unanticipated changes after release may explain some of the unpredictability of results of such procedures in cerebral palsy.

Effects of renal function on plasma digoxin levels in elderly ambulant patients in domiciliary practice.

An investigation into the relations between the daily dose of digoxin, drug regimen, serum digoxin concentration, and creatinine and digoxin clearance was carried out in a group of elderly ambulant patients in domiciliary practice. Moderate to severe impairment of renal function was found both in patients taking digoxin and in elderly control subjects. Plasma digoxin levels were not related to blood urea concentrations or creatinine clearance. Digoxin clearance was less than creatinine clearance. Now that plasma digoxin levels can be measured relatively easily their estimation should become part of clinical practice.
