The correct answer is  Intravenous Opioids are the mainstay of analgesia in neonates and infants in the postoperative period. Morphine and fentanyl are frequently used in neonatal ICU for analgesia. To reduce the likelihood of opioid tolerance, use of different opioids or addition of other medications such as intravenous naloxone and iv methadone are used. Ref: Clinical Anesthesia By Paul G.
