超声引导单次骶管阻滞在新生儿中的应用观察

目的 探讨超声引导单次骶管阻滞在新生儿中的应用价值。方法 选择2017年1月至2020年7月在###医院行肛门闭锁纠治术的男性新生儿50例,按随机数字表法分为传统体表标志定位骶管阻滞组(C 组)与超声引导骶管阻滞组(U 组),每组25例。两组患儿均在七氟烷浅全麻后行单次骶管阻滞。记录两组患者阻滞成功率、阻滞操作时间、穿刺针调整次数、穿刺失败率、阻滞并发症及术后6 h内的行为学评分法(CRIES)的评分。结果 与C组相比,U组患者阻滞成功率为100%,高于C组；穿刺针调整次数为(1.48±0.51)次,低于C组(2.12±0.72)次；术后1小时内CRIES量表评分低于C组；但阻滞操作时间(3.23±0.84 min)长于C组(1.84±0.69min)；差异均有统计学意义(P＜0.05)。结论 在新生儿中使用超声引导单次骶管阻滞可以提高阻滞的成功率,降低穿刺调整次数,改善术后疼痛评分,值得临床推广使用。

Application of ultrasound-guided single caudal block in neonates

183Application of ultrasound-guided single caudal block in neonates : Objective To explore the application value of ultrasound-guided single caudal block in neonates. Methods 50 neonates with anal atresia were randomly divided into two groups: Group C and Group U. Single Caudal block was performed after general anesthesia iduced by sevoflurane in both groups.The rate of successful block, the time of block operation, the adjustment times of puncture and the rate of failure, the complications of block and the CRIES pain scores within 6 hours after the operation were recorded. Results Compared with group C, the rate of successful block was higher in group U (100% vs 84%, P<0.05), the times of puncture was lower in group U (1.48±0.51 vs 2.12±0.72, P < 0.001), but the time of block operation was longer in group U (3.23±0.84 vs 1.84±0.69, P < 0.001).The scores of the CRIES scale within 1 hour after surgery was lower (P<0.05).Conclusion Application of ultrasound-guided single caudal block in neonates can improve the success rate of block, reduce the times of puncture, and improve postoperative pain scores.
