目的:探讨超声下腹直肌鞘阻滞在婴幼儿脐周手术中应用的临床效果及安全性。方法:将50例进行脐周手术婴幼儿随机分为A、B两组,每组25例。A组全麻后给予超声下腹直肌鞘阻滞,B组单纯全麻,观察两组患儿切皮反应、术中芬太尼用量、术后苏醒时间及术后镇痛效果。结果:A组患儿切皮前后平均动脉压(MAP)及心率(HR)无明显变化(P>0.05),B组患儿切皮后MAP、HR均较切皮前有明显上升(P<0.05);A组患儿术中芬太尼用量及术后苏醒时间均明显小于B组,术后镇痛满意的比例明显高于B组,差异有统计学意义(P<0.05)。结论:超声引导下腹直肌鞘阻滞麻醉效果确切,可减少全麻药用量,有利于患儿的术中管理和术后尽快苏醒。
Objective: To investigate the clinical effect and safety of ultrasound-assisted rectus sheath in the umbilical cord operation of infants. Methods: Fifty cases of infants who underwent umbilical operation were randomly divided into A and B groups, with 25 cases in each group. Group A was given anesthesia after ultrasound abdominal rectus sheath block, group B general anesthesia, two groups of children were observed skin incision, intraoperative fentanyl dosage, postoperative recovery time and postoperative analgesia. Results: There was no significant change in mean arterial pressure (MAP) and heart rate (HR) in group A before and after incision (P> 0.05). MAP and HR in group B were significantly higher than those before incision (P < 0.05). The dosage of fentanyl and the time of postoperative recovery in group A were significantly less than that in group B, and the rate of satisfactory postoperative analgesia was significantly higher than that in group B (P <0.05). Conclusion: Ultrasound guided rectus abdominis sheath block anesthesia is exact, can reduce the amount of general anesthesia, is conducive to children’s intraoperative management and wake up as soon as possible.
