Clinical & Coding Specifications
Clinical Context
A 62-year-old female is scheduled for an abdominoperineal resection under general anesthesia for a lower intraperitoneal malignancy. Preoperative evaluation in the hospital includes airway assessment, review of past medical history and medications, preoperative labs, and informed anesthesia discussion. In the operating room, standard monitors are applied, intravenous access is confirmed, and general endotracheal anesthesia is induced. Anesthesia is maintained during the laparoscopic and open phases of the abdominoperineal resection with hemodynamic and respiratory management, fluid administration, and analgesic techniques. Postoperative handoff is performed to the recovery unit with a plan for postoperative analgesia and monitoring.
