Few advancements in postoperative pain control in children have been made despite longstanding inadequacies in conventional intramuscular analgesic regimens. While overestimating narcotic complication rates, physicians often underestimate efficacious doses, nurses are reluctant to give injections, and many children in pain shy away from shots. This study prospectively focuses on the safety, efficacy, and complication rate of intermittent intramuscular (IM) versus continuous intravenous infusion (IV) of morphine sulfate (MS) in 46 nonventilated children following major chest, abdominal, or orthopedic surgical procedures. Twenty patients assigned to the IM group had a mean age of 6.17 years and a mean weight of 23.0 kg. Twenty-six patients assigned to the IV group had a mean age of 8.74 years and a mean weight of 27.4 kg. The mean IM MS dose was 12.3 micrograms/kg/h while the mean IV dose was 19.8 micrograms/kg/h (P less than .001). Postoperative pain was assessed with a linear analogue scale from 1 to 10 (1, "doesn't hurt"; 10, "worst hurt possible") for 3 days following operation. Using the analysis of covariance (ANACOVA), nurse, parent, and patient mean pain scores in the IV group were significantly lower than those of the IM group when controlled for age, MS dose, and complications (P less than .007). Nurse assessment of pain correlated well with the patient and parent assessments (Pearson correlation coefficients greater than 0.6). Not only did IV infusion give better pain relief than IM injections, but there were no major complications such as respiratory depression. Minor complications in this study (nausea, urinary retention, drowsiness, vomiting, hallucinations, lightheadedness, and prolonged ileus) were not significantly different between IM and IV groups.(ABSTRACT TRUNCATED AT 250 WORDS)

In a prospective, randomised, double-blind clinical study, we studied 32 ASA grade I and II boys aged 18 months to 12 years, scheduled for circumcision under general anaesthesia on an outpatient basis. They were randomly allocated to one of two groups: those in the ropivacaine group received caudal ropivacaine 0.2% 1 ml. kg-1 for postoperative analgesia and those in the ketamine/ropivacaine group received caudal ropivacaine 0.2% 1 ml. kg-1 plus caudal ketamine 0.25 mg.kg-1. Postoperative pain was assessed using a modified 10-cm visual analogue scale and analgesia was administered if the pain score exceeded a value of 3. The median duration of analgesia was significantly longer in the ketamine/ropivacaine group (12 h) than in the ropivacaine group (3 h, p < 0.0001), and subjects in the ropivacaine group required significantly more doses of postoperative analgesia than those in the ketamine/ropivacaine group (p < 0.0001). There were no differences between the groups in the incidence of postoperative nausea, vomiting, sedation, emergence delirium, nightmares, hallucinations, motor block and urinary retention.
