超声引导下腹横肌平面阻滞在小儿疝气手术中的应用

Ultrasound-guided transversus abdominis plane block in pediatric hernia surgery

目的探讨超声引导下腹横肌平面(TAP)阻滞用于小儿疝气手术中的效果。方法 46例小儿斜疝修补术患者随机分为两组各23例,观察组给予基础麻醉后实行超声引导下TAP阻滞,对照组仅予基础麻醉不予TAP阻滞,观察两组患儿切皮反应、术中KLS合剂用量、术后苏醒时间及术后镇痛效果。结果观察组患儿切皮前后MAP及HR无明显变化(P>0.05),对照组患儿切皮后MAP、HR均较切皮前有明显上升(P<0.05);观察组患儿术中KLS合剂用量及术后苏醒时间均明显小于对照组,术后镇痛满意的比例明显高于对照组,差异有统计学意义(P<0.05)。结论超声引导下TAP阻滞用于小儿腹股沟斜疝手术能取得更加有效的镇痛效果。

Objective To investigate the anesthetic effect of ultrasound-guided TAPblock in pediatric hernia surgery. Methods Forty six children with pediatric hernia surgery were randomly divided into two groups, the observation group treated by basic anesthesia and ultrasound-guided TAP block, and the control group treated by basic anesthesia only. The incision reaction, the KLS agent dosage, the recovery time after surgery and postoperative analgesia were observed. Results There were no significant changes in MAP and HR in the observation group before and after skin incision（P〉0.05）, and that in the control group were increased significantly after skin incision（P〈0.05）. The KLS agent dosage and postoperative recovery time in observation group were significantly less than those in the control group, and analgesia satisfactory postoperative was significantly higher than that in the control group（P〈0.05）. Conclusion Ultrasound guided TAP block in pediatric inguinal hernia surgery is an effective method in providing analgesic.
