Anaesth Intensive Care · May 1975
Comparative StudyControl of heat balance during arterial surgery.
Patients were studied to quantitate methods used to prevent heat loss during vascular surgery. A combination of techniques limiting heat loss were shown to prevent hypothermia. In addition it was shown that heat balance in patients undergoing vascular surgery did not differ from that in patients undergoing other forms of surgery.

Two patients with tetanus are reported to illustrate the involvement of the sympathetic and parasympathetic nervous system respectively. Aspects of the autonomic manifestations of tetanus are illustrated and discussed.

The incidence and management of severe drug overdose patients over a five-year period is presented, together with results and complications. Emphasis is placed on the importance of conservative measures with minimal need for more aggressive methods of treatment.

Three groups of adult patients were anaesthetized for elective intra-abdominal surgery. In one group, patients were ventilated with dry anaesthetic gases, and these patients all lost heat. ⋯ The third group, in addition to humidification, had surface insulation and all these patients gained heat. It is suggested that conservative methods which negate heat loss are able to prevent hypothermia by the retention of metabolically produced heat.
