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.

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.

Case Reports Comparative StudyGeneral anaesthesia versus epidural block for caesarean section in patient with pre-eclampsia.
To protect mother and fetus from the stress of vaginal delivery, caesarean section is to be chosen in severe cases of pre-eclampsia. When general anaesthesia is used, attention must be paid to the increase in arterial pressure, pulmonary arterial pressure (PA) and pulmonary capillary wedge pressure (PCW), which occur during intubation, tracheal suction and extubation. In epidural block, on the other hand, hypotension is a common phenomenon if the hypovolaemia is not corrected before the anaesthesia. It is important for the anaesthesiologist to see these women early to be able to treat the hypovolaemia and hypertension prior to caesarean section.
