问题 单项选择题 A1型题

患者女,25岁。左侧完全性唇裂术后继发畸形,拟进行二期手术矫正,应采取的麻醉方法是()

A.局部浸润麻醉

B.双侧眶下神经阻滞麻醉

C.基础麻醉加局部浸润麻醉

D.全身麻醉

E.鼻腭神经阻滞麻醉

答案

参考答案:B

解析:对于唇腭裂患者2岁前完成唇腭裂手术,但有些患者随后出现鼻畸形,需要在12岁以后进行二期手术时才能修复,双侧眶下神经阻滞麻醉可以使鼻侧从下眼睑到上唇的皮肤和黏膜产生无痛,满足做唇腭裂二期鼻畸形的修复,所以B正确。局部浸润麻醉效果不好,造成软组织肿胀不易进行手术操作,所以A、C不选;E麻醉的部位不正确,不能使手术区域无痛,所以E不选;全身麻醉没有必要,增加花费和手术风险,所以D不选,所以此题选B。
