The effect of intravenous metronidazole as prophylaxis against postoperative wound infection was studied in a prospective, randomized, double-blind controlled trial of 116 patients undergoing elective cholecystectomy. No significant difference was found in the infection rate between the treated and the control groups.
The effect on digital blood flow of an acute exposure to vibration has been assessed. Vibration in the frequency range 40-200 Hz reduces digital blood flow, the effect being maximal at 120 Hz. Increasing the amplitude of vibration reduces digital blood flow. The results have implications in the formulation of industrial vibration standards and in the pathophysiology of vibration-induced white finger.
