Pain management after tonsillectomy: morphine is not enough

J Otolaryngol Head Neck Surg. 2008 Apr;37(2):279-84.

Abstract

Introduction: Tonsillectomy is usually done as day surgery, transferring to the parents most of the postoperative care. They often feel alone and incompetent in front of a child in pain. We developed a guide to help parents for both the evaluation and the management of postoperative pain.

Objective: To improve pediatric posttonsillectomy pain management with the implementation of a parental guide and treatment algorithm.

Methods: Eighty children (5-17 years) were recruited in this randomized clinical trial. Parents and children were assigned to one of the research groups: control or experimental. All received an identical prescription for acetaminophen (15 mg/kg) and morphine (0.3 mg/kg), information about the medication, a visual analogue scale (VAS), and index cards to be filled at home. The experimental group also received a treatment algorithm associating pain scores with analgesics.

Results: Pain scores for the control group and the experimental group were 5.3 and 4.7 on the day of surgery, 4.0 and 3.6 the next day, 2.2 and 2.3 3 days later, and 1.6 and 1.4 1 week after the intervention, respectively. The side effects and the analgesics given were comparable for both groups.

Conclusion: No significant difference was demonstrated for the studied parameters, probably because the majority of the parents followed the prescriptions well. The guide was much appreciated. The children understood the VAS easily and liked using it. The combination of acetaminophen-morphine needs to be revisited since pain remains problematic.
