Int J Oral Surg:低血压麻醉不是正颌术后单眼失明的主要原因

2018-01-07 MedSci MedSci原创

非眼部手术中的围手术期视力丧失是多种原因所致的罕见且破坏性强的并发症。

非眼部手术中的围手术期视力丧失是多种原因所致的罕见且破坏性强的并发症。视觉系统的任何部分都可能涉及,一些作者试图将这种并发症与用于控制术中出血的低血压麻醉技术相关联。我们研究了一名正颌手术后单侧失明的患者。经过对类似病例的回顾,我们发现Le fort I截骨术中产生的力的传递与并发症有关。作者所在医院在这种截骨技术中经常使用弯曲的骨切开器进行翼上颌骨的分离,该作用力通过蝶骨传输是视神经及其血管结构间接损伤导致神经病变和失明的主要原因。由于减少眼压灌注,降压麻醉在某些特定病例中肯定会导致短暂的局部缺血。
