A 63-year-old woman comes to your outpatient facility for an abdominoplasty and liposuction of her thighs and buttocks. During the five-hour procedure, she receives more than three liters of intravenous fluids, and the surgeon injects three liters of fluid for the ultrasonic-assisted suction lipectomy. When she reaches the post-anesthesia care unit, her temperature is 93'F, she is hypertensive, and her shivering rattles the stretcher rails.
