Patient-controlled analgesia in pediatric surgery.

Patient-controlled analgesia (PCA) with a microprocessor-operated infusion syringe was first suggested for human use in 1965. Clinical studies from the United States and Europe have shown this form of analgesia to be well accepted by adults, but the use of this technology for children has not been studied. We evaluated PCA in 15 consecutive pediatric surgical patients between the ages of 11 and 18 years undergoing major thoracic or abdominal surgery. The patients and their parents were instructed in the use of the equipment prior to surgery and PCA was initiated after the patients left the recovery room. The mean duration of PCA was 2.6 days. No serious mechanical difficulties with the infusion apparatus were encountered. The acceptance of PCA was excellent with only two patients preferring some other method of analgesia. Pain relief was assessed twice daily by a registered nurse using a verbal-visual pain scale. On a 1 to 10 scale average pain relief was 7.2. Eight of the patients had had a previous operation, and seven of these reported that PCA was a better method of achieving pain control. A comparison of the 15 study patients with 15 previous patients with similar procedures indicated that PCA patients used less analgesia in the postoperative period, although they tended to use more in the first 24 hours. PCA is found to be a safe and effective means of analgesia in pediatric patients. Adequate pain relief was achieved with less analgesia and with less nursing attention. This technology is recommended for postoperative pediatric patients.
