A collaborative effort to improve pain control in the young pediatric patient resulted in new policies and a change in pain management practice. A retrospective chart review of 15 pediatric surgical patients identified the use of patient controlled analgesia (PCA) as a successful method of pain control for children 3 years of age and older.

Postoperative pain management in children is a topic that has been neglected in the past but is currently an active field of interest and effort. Clearly, the child's cognitive understanding of and emotional response to pain are different than an adult's, and these differences make pain assessment and control more difficult. ⋯ The effects of untreated pain in children are similar to those in adults but may have more long-term consequences in children. In the past, postoperative pain treatment in children was often inadequate, but newer techniques, such as continuous infusion of opioids, patient-controlled analgesia, epidural administration of opioids, and regional analgesia, hold promise for improved care in the future.

Postoperative patient-controlled analgesia with sufentanil: analgesic efficacy and minimum effective concentrations.
Sufentanil has so far seldom been used for intravenous postoperative patient-controlled analgesia (PCA), and the resulting serum concentrations have not yet been determined. Forty ASA I-III patients recovering from major gynecological operations were investigated to evaluate analgesic efficacy, side effects, patient acceptance and threshold concentrations of sufentanil in serum during the early postoperative period, using the On-Demand Analgesia Computer (ODAC). Following an individualized intravenous loading dose of 19.1 +/- 35.7 micrograms (mean +/- 1 s.d.), sufentanil demand doses were 6 micrograms with a concurrent infusion of 1.15 micrograms/h and a maximum hourly dose of 40 micrograms/h; the lockout time was set to 1 min. ⋯ Intraindividual MEC variability was slightly lower than intersubject variability (76.0 vs. 84.8%). It is concluded that sufentanil is suitable for postoperative PCA. To get into the therapeutic window for analgesia, a serum sufentanil concentration of more than 0.03 ng/ml seems to be necessary.

The authors report their experience with low doses (0.007-0.015 mg/kg), moderate doses (0.016-0.025 mg/kg), and high doses (0.026-0.035 mg/kg) of intrathecal morphine for postoperative analgesia after selective dorsal root rhizotomy surgery in 50 children, aged 3 to 12 years. After closure of the dura, a single dose of preservative-free morphine was injected into the subarachnoid space, and patients were assessed for 48 hours for level of comfort and side effects. The three doses of morphine provided equivalent analgesia and similar side effects. ⋯ No patient experienced late respiratory depression or generalized pruritus. The authors conclude that low doses of intrathecal morphine is as effective as moderate or high doses of morphine for reducing pain in the immediate postoperative period. Intrathecal morphine provides excellent analgesia after selective dorsal rhizotomy.
