目的 :为减少小儿鼻内窥镜手术中的出血 ,我院采用全麻控制性降压 ,从而达到顺利完成手术的目的。方法 :将72例小儿鼻息肉、鼻窦炎患者随机分成A、B两组 ,A组实行单纯全麻下手术 ,B组实行全麻控制性降压 ,术中均用2 %利多卡因20ml加1‰肾上腺素4ml浸润的棉片止血 ,观察A、B两组术中出血情况。结果 :实行全麻控制性降压的B组比单纯全麻下手术A组术中出血平均减少76ml,差异有显著性(P<0.001)。结论 :全麻控制性降压可明显减少小儿鼻内窥镜手术中的出血
Objective: To reduce bleeding during pediatric endoscopic sinus surgery, our hospital controlled general anesthesia with antihypertensive effect, so as to achieve the goal of successful operation. Methods: Seventy-two children with nasal polyps and sinusitis were randomly divided into A and B groups. Group A underwent operation under general anesthesia and group B under general anesthesia with controlled hypotension. All patients were treated with 20% lidocaine 2% 1 ‰ epinephrine 4ml infiltration of cotton hemostasis observed A, B two groups of intraoperative bleeding. Results: The average blood pressure in group B with controlled hypotension of general anesthesia was 76ml less than that of group A alone (P <0.001). Conclusion: Controlled general anesthesia can significantly reduce the bleeding in pediatric endoscopic sinus surgery
