We report a case of a 59-year-old woman who presented with
hypovolemic shock and compensated
acidosis (preoperative arterial blood
gases: pH 7.3, P(CO2) 31.9 mmHg, Pa(O2) 112.3 mmHg, base excess -9.8, Hb 6.4 g x dl(-1)) due to perforated descending colon, necessitating emergency surgery. Tracheal intubation had been performed preoperatively. Prior to induction of
anesthesia, blood pressure was 106/74 mmHg, heart rate 119 beats x min(-1), and Sp(O2) 100% breathing room air.
Anesthesia was induced with
remifentanil influsion at a rate of 0.05 mg x kg(-1) x min(-1),
sevoflurane 1% and
rocuronium bromide 30mg, and was maintained with
oxygen, air,
remifentanil and
sevoflurane. For a critical
hypovolemia, in accordance to the guidelines for intraoperative critical
hemorrhage and the Japanese practical guidelines for blood components
therapy, we started to transfuse incompatible red cell (O+) since the identification of blood typing was suspended. The duration of surgery was 104 min, with an intraoperative total
bleeding of 125 ml. Four units of total
blood transfusion and 3,050 ml of infusion of
Ringer's acetate solution were administered. The patient was transferred to ICU with tracheal intubation. No adverse reactions associated with blood type incompatibility were recognized.
