Abstract
Anesthesia care has evolved over time. Considerable importance is now given to postoperative care, rather than just good pre/intraoperative care. As the number of operations is increasing, it has become important for patients to recover rapidly without side effects. This has lead to the development of newer anesthesia techniques and recovery protocols. Complications in the postanesthesia care unit (PACU) are frequent, and therefore, identification and timely management of these complications decreases patient morbidity and mortality. Standards of postoperative care are summarized below.

A 35-year-old patient is brought to the PACU after undergoing an appendectomy. His anesthetics included propofol 140 mg, isoflurane 2.0 MAC, vecuronium 6 mg, and morphine 6 mg. In the PACU the patient’s temperature is 33.5 C and is shivering. The most likely cause of his shivering is
