The most important complications following gastrointestinal surgery are related to disruption of anastomoses. The fate of a gastrointestinal anastomosis is influenced by many factors. Among these, care in the anaesthetic management and postoperative treatment may reduce the incidence of complications. ⋯ The prevention of high intra-luminal pressures and excessive longitudinal traction across anastomoses may be aided by care in the administration of neostigmine, and possibly by the avoidance of morphine for provision of intra-operative and postoperative analgesia. Maintenance of, or improvements in, oxygen supply to an anastomosis may be achieved by avoiding hypoxia, hypocapnia and hypovolaemia, and by the use of regional anaesthetic techniques during surgery and/or in the post-operative period. In addition, sedative and analgesic therapy may influence the incidence of postoperative ileus, and may thus contribute to morbidity.

Case Reports Comparative Study
Anaesthesia for patients with multiple sclerosis.
The types of anaesthesia administered to 56 multiple sclerosis patients undergoing surgery in the different departments of the Helsinki University Central Hospital (HUCH) during a ten year period from 1973 to 1982 were studied. The perioperative and postoperative events were analyzed in relation to the method of anaesthesia. ⋯ In four patients who were given regional anaesthesia (2 spinal, 3 epidural) marked by hypotension, quite resistant to intravenous vasopressor treatment was observed. No deterioration of the multiple sclerosis was noted postoperatively which could be related to the anaesthesia.

The use of cutaneous liquid crystal thermometry (EZ Temp) as an estimate of core temperature during routine surgery was investigated in 20 patients. Seventeen per cent of the recordings made with the EZ Temp were more than 1 degree C different from oesophageal temperature. There was a poor correlation between EZ Temp values and both oesophageal and aural temperatures (r = 0.54 for both sites). We conclude that liquid crystal thermometry of the forehead is not sufficiently accurate to be used as an indicator of core temperature during routine surgery.
