Case Reports
[Postoperative disturbance of consciousness due to tumor emboli of the orifice of pulmonary artery].
We reported a case of an abrupt hypotension and hypoxemia which lasted more than 60 min due to emboli of tumor at the orifice of the pulmonary artery during operation. Although the emboli were removed under the cardiopulmonary bypass (CPB) and later the patient regained good respiratory and hemodynamic conditions, he had a disturbance of consciousness after the operation. ⋯ His consciousness improved quickly after the beginning of OHP. We conclude that OHP and CPB might be useful to treat the postoperative disturbance of consciousness due to hypotension and hypoxemia during operation.

Postoperative analgesia with epidurally injected buprenorphine and its side effects were investigated in 100 patients who had received lower abdominal surgery. All patients received initially 8 ml of bupivacaine and 0.1 mg of buprenorphine. ⋯ No significant difference in the incidence of side-effect was found among groups C, D, E. We conclude that a dose of a approximately 15 micrograms.h-1 might be optimal for postoperative pain relief after lower abdominal surgery.
