Upon emergence from anesthesia after a short desflurane case with remifentanil, which is the most likely issue?

• A. Adequate analgesia for 2 hours
• B. Delayed emergence from narcotic
• C. Pain
• D. Respiratory depression in PACU

Answer: (C)

Remifentanil is an ultra-short-acting opioid that provides intraoperative analgesia but wears off very quickly once the infusion stops. In a short desflurane case, the anesthetic is wearing off and the patient is waking, but there isn’t lingering analgesia from the opioid. The most likely issue at emergence is pain because the postoperative analgesia hasn’t yet taken effect or been provided, so the patient becomes uncomfortable as the anesthetic symptoms subside. Understanding this helps reconcile why delayed emergence from narcotics or respiratory depression in the PACU are less likely in this scenario: remifentanil does not accumulate and does not prolong sedation or delay emergence, and its effect ends rapidly after the infusion stops. Adequate analgesia lasting for hours after a brief procedure would require a different analgesic strategy beyond what remifentanil alone provides, which is why pain on emergence is the most expected issue.
