• American Society of Anesthesiologists physical status I, II or III
• Body weight of at least 40.0 kilogram (kg)
• Postoperative participants who have undergone general or regional anesthesia for abdominal, pelvic/genitourinary, orthopedic, or thoracic surgery

• Participants who are awake and breathing spontaneously with a respiratory rate of 14 to 18 breaths per minute, peripheral capillary oxygen saturation ≥93% (with or without supplemental oxygen), and able to answer questions and follow commands
• Participants who have been observed during recovery, who are awake, able to answer questions and follow commands, and who have been comfortable for at least 30 minutes, with a pain intensity score ≤4 (numeric rating scale 0-10), with or without titration to comfort with IV opioids

Exclusion Criteria:

• Participants who have undergone any surgery on the airway, head, or neck
• Participants who received an extended-release opioid within 48 hours prior to Hour 0 or who are expected to have postoperative analgesia supplied by a continuous regional technique or participant-controlled epidural analgesia

• Participants who received intra-operative and/or postoperative administration of opioids other than morphine, hydromorphone, fentanyl, sufentanil, or alfentanil. Exception: If there are no medical contraindications, meperidine (pethidine) up to 0.5 milligram/kg IV is permitted during recovery for shivering
