[Coronary spasm during repeated anesthesia].

Coronary arterial spasm observed during the course of two repeated anaesthesias in a patient having undergone aorto-femoral bypass grafting is reported by the authors. Such complications are accompanied by serious ventricular arrhythmias, though transient and healing without sequelae. Clinical and electrocardiographic characteristics of peroperative coronary arterial spasm are underlined. In patients prone to developing such spasm, peroperative alkalosis, hypothermia and parasympathetic stimuli should be avoided. Are emphasized the efficiency of preventive treatment with calcium antagonists and that of intravenous nitroglycerin in the treatment of peroperative coronary arterial spasm when it does occur.
