Randomized Controlled Trial Comparative Study
[Effect of amino acid solution on intraoperative core temperature the influence of anesthetics].
Propofol anesthesia has more thermogenic effect than isoflurane when combined with amino acid solutions. The purpose of this study is to compare the effects of intraoperative administration of amino acid solutions on intraoperative core temperature under propofol anesthesia with those under sevoflurane anesthesia. ⋯ Sevoflurane anesthesia has more preventive effect on intraoperative hypothermia than propofol anesthesia when combined with amino acid solutions.

Randomized Controlled Trial
[Effects of clonidine and midazolam on postoperative shivering, nausea, and vomiting].
Postoperative shivering, nausea, and vomiting are common problems after general anesthesia. We compared the effects of clonidine and those of midazolam on postoperative shivering, nausea and vomiting in elderly patients. ⋯ Clonidine premedication is effective for preventing shivering and nausea after general anesthesia combined with epidural anesthesia.

We report a postpneumonectomy patient who underwent partial lobectomy. A 74-year-old man was scheduled for right partial lobectomy because of metastatic lung cancer. He had undergone left pneumonectomy 19 months before because of lung cancer. ⋯ During surgery, respiration was maintained with mechanical and intermittent manual ventilation. Percutaneous cardiopulmonary support and high frequency jet ventilation were at hand but were not needed. There was no intraoperative hypoxia and the postoperative course was uneventful.

Asystole during electroconvulsive therapy (ECT) has been reported as an uncommon but fatal complication. But cardiac movement during electrical stimulation has not been well known. ⋯ Electrical stimulation by ECT activates parasympathetic nervous system and convulsion by the stimulation activates sympathetic nervous system. As asystole case had good reactive automatic nervous system, asystole might have been provoked by the stimulation with a greater increase in RPP after the stimulation.

We describe a patient to whom ropivacaine 150 mg had been administered during obturator nerve blockade and developed grand mal convulsions because of inadvertent i.v. injection. Venous blood samples were taken 15, 32 and 52 min after the convulsion. ⋯ The peak plasma concentration at the time of the inadvertent i.v. injection was estimated to be 6.6 microg x ml(-1). The patient recovered uneventfully.
