Intrathecal morphine for postoperative analgesia in an infant with bronchopulmonary dysplasia following upper abdominal surgery.

We present a case of severe bronchopulmonary dysplasia in which intrathecal morphine was successfully used for analgesia after a Nissen fundoplication and gastrostomy. Various options for anaesthesia are discussed with the knowledge that two previous procedures had been complicated by congestive cardiac failure and increased respiratory failure.

Intrathecal morphine (ITM) for postoperative pain control in children: a comparison with nalbuphine patient controlled analgesia (PCA).

This is a retrospective study covering the ten-year period 1984-1993. Single shot spinal morphine (ITM) is compared with PCA nalbuphine for postoperative pain relief in children having abdominal or thoracic procedures. The records of 52 patients meeting selection criteria were examined. Nursing and physician notations were reviewed for hourly pain assessments, evidence of associated complications, respiratory depression, nausea and or vomiting, pruritus, and urinary retention. ITM provided significantly better pain relief (2.2 h in pain) during the first 24 h postoperatively than PCA nalbuphine (9.2 h in pain). With the exception of urinary retention which was significantly more frequent following ITM (58.6%) compared to PCA nalbuphine (8.7%), narcotic related complications were not different between the two groups. No difference in duration of hospital stay or ICU stay could be demonstrated. We conclude that ITM provides better pain relief, without more serious complications, than PCA nalbuphine. We recommend it as a safe, effective technique to treat postoperative pain in children following thoracic or upper abdominal procedures.

The effects of propofol anesthesia on transcortical electric evoked potentials in the rat.

The effects of halogenated anesthetic agents on somatosensory and motor evoked potentials (MEP) have been documented previously. Intravenous anesthetic propofol has not yet been used during MEP monitoring. This study investigates the effects of propofol on transcortical MEP in rats during bolus, infusion, and recovery conditions. After baseline MEP recordings, animals received a hetastarch bolus, followed by a propofol (10 mg/kg) bolus dose. A propofol infusion (10 mg/kg/h) and a hetastarch infusion were then begun. MEP recordings were obtained after the propofol bolus, during the infusion, and after a 30-minute recovery phase. Blood pressure readings remained stable. MEP onset latency increased, and amplitude decreased. Response duration diminished. All values returned towards the baseline during recovery. Our results show that the effects of propofol on MEPs are similar to its effects on somatosensory evoked potentials. Propofol seems to be a reasonable agent for use during intraoperative MEP monitoring and should be further investigated for use during spinal cord monitoring in humans.

Naloxone: report of a beneficial side effect.

We report two cases. The first was an unexpected, complete resolution of an acute unilateral neurologic deficit associated with anesthesia when naloxone was administered to reverse residual narcotic effect. The second was a complete resolution of postoperative unilateral electroencephalographic evidence of ischemia after naloxone administration in a patient following a carotid endarterectomy. A literature search suggests that naloxone may be useful in the treatment of acute and hyperacute stroke due to ischemia.
