ABSTRACT
BACKGROUND: Recent publications from the United States, India, and Korea report that children undergoing hypospadias repair with caudal regional anesthesia/analgesia could have increased postoperative surgical complications. AIMS: The purpose of this retrospective cohort study was to assess the impact between caudal regional anesthesia, other regional anesthesia, and no regional anesthesia on complications after hypospadias repair at a tertiary care children's hospital in Ottawa, Canada, with an expectation to changing practices if a link was found. METHOD: We reviewed the health records of 827 children with hypospadias undergoing penile surgery from January 1991-June 2017. The final sample size for the analysis consisted of 764 patients and 825 procedures. RESULTS: The overall complications were almost identical when considering anesthesia effects, and this similarity persisted when we assessed specifically for only surgical complications. We had 716, 94, and 15 subjects who had a caudal block, penile block, and general anesthesia only, respectively, and their complication rates were 28, 31, and 27%, respectively, and their fistula formation rates were 10, 6, and 0%, respectively, and their stricture formation rates were 8, 7, and 20%,, respectively. Hypospadias type and surgical repair technique were marked predictors of complications in the postoperative period. CONCLUSION: Anesthesia technique appears to have minor impact on complications after hypospadias repair, while surgical technique and type of hypospadias impact complications after hypospadias surgery in children. Based upon these results, we will not change our current practice of using a variety of regional anesthesia techniques for children undergoing hypospadias repair.

PURPOSE: Corrective strabismus surgery is associated with moderate pain after surgery. Postoperative analgesia for these patients may include topical local anesthetic agents and topical non-steroidal anti-inflammatory drugs. In this prospective randomized, double-blind placebo controlled clinical trial we compared the effect of placebo to intraoperative 0.5% topical amethocaine or 0.5% topical ketorolac on pain control after strabismus surgery in children. METHODS: Following Institutional Ethics Committee approval and parental consent, we prospectively studied 51 healthy children between the ages of two and seven years who were undergoing elective bilateral recession surgery in a randomized, double-blind controlled clinical trial. Children were randomized to receive either placebo (normal saline), 0.5% amethocaine or 0.5% ketorolac eye drops at the start and end of strabismus repair surgery. Pain was assessed with a modified Children's Hospital of Eastern Ontario Pain Score in the recovery room. If the pain score was greater than 6, the patient was administered a single oral dose of acetaminophen (20 mg x kg(-1)). RESULTS: The groups had similar demographic data. Duration of surgery and anesthesia, time spent in recovery room and length of hospital stay between the three groups were similar. Pain scores and analgesic requirements while in the hospital were also similar between the groups as was the time to first analgesic administration. There were no side effects observed in any of the three treatment arms. CONCLUSION: We conclude that there is no improvement in postoperative pain control after the intraoperative administration of topical 0.5% ketorolac or 0.5% amethocaine when compared to placebo in children undergoing strabismus surgery.

PURPOSE: To investigate if 50% nitrous oxide reduces the pain during injection of propofol mixed with lidocaine in children. METHODS: Healthy children undergoing iv induction of general anesthesia for elective surgery were recruited into this prospective, randomized, double-blind study. None of the patients received any premedication except for eutectic mixture of local anesthetics cream. Before induction of anesthesia with propofol 1% mixed with lidocaine 0.05% (propofol dose 3 mg x kg(-1)), the treatment group received 50% N(2)O in O(2) and the control group received 100% oxygen. Pain due to propofol administration was rated with a four-point behavioural scale: none, mild, moderate or severe. RESULTS: There were 28 subjects in the control group and 26 subjects in the treatment group. Demographic data were similar in both groups. The incidence of pain at induction was 4% after N(2)O and 36% in the control group, P < 0.01. No patients had severe pain. Most patients had mild pain. Three of the ten patients with pain in the control group had moderate pain. The number needed to treat was 3:1. CONCLUSION: Nitrous oxide reduces pain during induction with propofol mixed with lidocaine in healthy children.
