[TURP syndrome with severe hyponatremia (98 mEq x l(-1)): a report of a case].

We report a case of transurethral resection of prostate (TURP) syndrome with severe hyponatremia (98 mEq x l(-1)). A relatively healthy 71-year-old man (167 cm and 61 kg) with benign prostatic hypertrophy was scheduled for transurethral resection of the prostate under general anesthesia. Ninety minutes after starting the operation, electrolyte analysis revealed a decrease in serum Na concentration (Na 98 mEq x l(-1), BE -6.

[Effect of amino acid infusion for prevention of intraoperative hypothermia during laparotomy].

Background: Amino acid infusion prevents intraoperative hypothermia. The purpose of this study is to examine the effect of amino acid infusion on intraoperative core temperature of patients during laparotomy.

Methods: Forty-two patients (duration of surgery of 180 min or more) and 32 patients (duration of surgery less than 180 min) scheduled for open gastrectomy under sevoflurane anesthesia combined with epidural anesthesia were randomly allocated to receive either amino acid solution (A group) or electrolyte solution (S group) intravenously.
