产妇椎管内麻醉后发生神经损伤的影响因素分析

Analysis of the influencing factors of nerve injury after intraspinal anesthesia of puerpera

目的:分析产妇经椎管内麻醉后发生神经损伤的影响因素。方法:选取椎管内麻醉下行子宫下段剖宫术产妇350例,其中神经损伤组40例,无神经损伤组310例。比较2组产妇的体质量、年龄、孕龄、术前合并疾病、麻醉操作时是否有异物感以及孕末期水肿情况等。结果:2组产妇的年龄、身高、体质量及孕龄差异均无统计学意义(P>0.05);神经损伤组产妇在麻醉时有异物感率为80.0%,明显高于无神经损伤组的2.2%(P<0.01);神经损伤组产妇孕期水肿发生率为65.0%,显著高于无神经损伤组的6.5%(P<0.01)。结论:熟练并规范的椎管内麻醉术有助于减少产妇术后神经损伤的发生,同时减少异物感及产妇孕期水肿程度。

Objective： To analyze the related factors of nerve injury after intraspinal anesthesia of puerpera. Methods： Three hundred and fifty puerperas treated with lower uterus cesarean section under intraspinal anesthesia were divided into the nerve injury group（ 40cases） and non-nerve injury group（ 310 cases）. The body weight,age,gestational age,preoperative comorbidities,different sense during anesthesia and edema during late pregnancy between groups were analyzed. Results： The differences of the age,height,body mass and gestational age between two groups were not statistically significant（ P〉0. 05）. The foreign body sensation rate in nerve injury group during anesthesia（ 80. 0%） was significantly higher than that in non-nerve injury group（ 2. 2%）（ P〈0. 01）. The rate of pregnancy edeman in nerve injury group（ 65. 0%） was significantly higher than that in non-nerve injury group（ 6. 5%）（ P〈0. 01）. Conclusions：The skilled and specification operation in intraspinal anesthesia can reduce the occurrence of postoperative nerve injury,foreign body sensation and maternal pregnancy edema.
