Abstract:
Objective:To compare the different optimized anesthesia strategies in pediatric patients undergoing hypospadias surgery.Methods:Ninety pediatric patients with distal hypospadias undergoing Duckett operation, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, aged 1-6 yr, weighing 10-25 kg, were divided into 3 groups ( n=30 each) using a random number table method: caudal block combined with general anesthesia group (group CG), neurostimulator-guided pudendal nerve block combined with general anesthesia group (group PG) and ultrasound-guided dorsal penile nerve block combined with general anesthesia group (group DPG). Anesthesia was induced with propofol-fentanyl, patients were ventilated through the laryngeal mask and maintained spontaneous breathing, and anesthesia was maintained with sevoflurane.The corresponding regional block was performed in each group, and block was performed with 0.25% ropivacaine 1, 0.25 and 0.15 ml/kg in CG, PG and DPG groups, respectively.The consumption of ropivacaine, occurrence of insufficient analgesia during operation, emergence time, duration of post-anesthesia care unit stay, time of the first requirement for analgesics, requirement for analgesics within 24 h after operation, occurrence of postoperative agitation, nausea and vomiting and lower extremity motor block, and patients′ satisfaction score at 24 h after operation were recorded. Results:Compared with group CG, the consumption of ropivacaine was significantly reduced, the time of the first requirement for analgesics was prolonged, the postoperative requirement for analgesics was decreased, duration of post-anesthesia care unit stay was shortened, the incidence of lower extremity motor block was decreased, and patients′ satisfaction score was increased in group PG and group DPG, and the incidence of nausea and vomiting was decreased in group DPG ( P<0.05). Compared with group PG, the consumption of ropivacaine was significantly reduced, and the time of the first requirement for analgesics was shortened in group DPG ( P<0.05). There was no significant difference in the incidence of insufficient analgesia during operation (3% in group DPG) and incidence of postoperative agitation among the three groups ( P>0.05). Conclusion:Ultrasound-guided dorsal penile nerve block combined with general anesthesia provides significant efficacy with a higher safety, and the efficacy is better than that of caudal block combined with general anesthesia and neurostimulator-guided pudendal nerve block general anesthesia when used for pediatric patients undergoing hypospadias surgery.
