The levels of cephradine were measured in serum, voluntary muscle and subcutaneous fat samples collected from 30 patients during surgical operations for peripheral vascular disease. Cephradine 2 g was administered in two equal doses by intramuscular and intravenous routes before each operation. The mean levels found in the serum and muscle were well above the minimum inhibitory concentrations required for most important Gram-positive and Gram-negative pathogens, in contrast to the relatively low mean level found in subcutaneous fat.

Comparative Study Clinical Trial Controlled Clinical Trial
Analgesia following oral surgery for day patients: a clincial comparison of two analgesics.
A single-blind, between-patient study was carried out in 167 patients following oral surgery to compare the effectiveness and tolerance of two combination analgesic preparations; pentazocine (15 mg) plus paracetamol (500 mg) and dextropropoxyphene hydrochloride (32.5 mg) plus paracetamol (325 mg). Assessments of pain and pain relief were made over two periods, initially over the 90 minute period following administration of either preparation and secondly, over the subsequent 3 days following discharge. At the hospital, those patients receiving pentazocine plus paracetamol achieved a greater relief of pain than those receiving dextropropoxyphene plus paracetamol, though the differences did not reach statistical significance. At home, pain relief was very similar for both groups of patients, both preparations being effective and well tolerated.

A clinical study was carried out to evaluate the usefulness of intravenous lorazepam, given for sedation instead of opiate narcotics or diazepam, in 25 seriously-ill patients being treated in a respiratory and intensive care unit. All but 3 patients were on assisted ventilation. Standard doses of 4 mg lorazepam were given at 4 or 6-hourly intervals for periods up to 25 days. ⋯ No side-effects were reported, nor was there any local reaction to the injection. Cardiac output was measured in 9 patients following intravenous administration of a single-dose of either 4 mg or 8 mg lorazepam. No significant changes were recorded.
