General Issues in Perioperative Care
摘要
A 25-year-old woman who developed severe post-partum hemorrhage after delivery of a still-born baby was taken up for emergency hysterectomy under general anesthesia with rapid sequence intubation using 150 mg thiopentone, rocuronium 50 mg, fentanyl 50 mcg, 7.5 mm tracheal tube, and controlled ventilation with FiO2 of 1.0 and 0.8 MAC sevoflurane. During the procedure, the patient was administered 3 units of whole blood, 1 unit of FFP, and 2 liters of Ringer’s lactate solution. Dopamine infusion was used to maintain the mean blood pressure around 70 mmHg. At the end of the procedure, the patient was transferred to the ICU without reversal of neuromuscular blockade. In the ICU, the patient was mechanically ventilated and the dopamine was tapered off. The patient was hypothermic and anuric, with a hemoglobin of 6.5 g/dl, platelet count of 37000/mm3, INR of 5.1, urea of 50 mg/dl, creatinine of 2.7 mg/dl, and raised liver enzymes. ECG showed tall T waves and a blood gas analysis showed serum potassium of 6.1. Corrective measures for hyperkalemia were instituted and the patient was allowed to rewarm. After overnight ventilation and one episode of hemodialysis, the patient was extubated. Hemodialysis continued for another two days until the patient’s urine output improved.
