目的:探讨术侧上肢抱枕位对桥小脑角区肿瘤切除术患者血流动力学和安全性的影响。方法:选择2016年1月至2019年12月暨南大学医学院附属广州市红十字会医院住院的84例行桥小脑角区肿瘤切除术患者为研究对象。按照随机数字表法分为试验组和对照组各42例。对照组术侧上肢采用常规手术体位摆放，试验组将术侧上肢摆放为抱枕位。记录患者入室时、体位摆放结束、手术30 min、手术60 min、术毕时收缩压、舒张压、心率和血氧饱和度等指标，比较2组患者术后上肢麻木/酸痛和压力性损伤发生率。结果:2组患者手术前后各时段收缩压、舒张压、心率和血氧饱和度差异无统计学意义（n P>0.05）。试验组上肢麻木/酸痛发生率为2.4%（1/42），对照组为19.1%（8/42），差异有统计学意义（n χ2值为6.098，n P<0.05）。压力性损伤1期试验组为2例，对照组为6例，压力性损伤2期对照组为2例，2组比较差异有统计学意义（n Z值为2.039，n P<0.05）。n 结论:术侧上肢抱枕位可明显降低桥小脑角肿瘤切除术患者术后并发症发生率，且不增加患者血流动力学异常波动风险。“,”Objective:To investigate the effect of upper limb pillow position on hemodynamic and safety of patients undergoing cerebellopontine angle tumor resection.Methods:Eighty-four patients receiving cerebellopontine angle tumor resection in our hospital from January 2016 to December 2019 were randomly divided into the experimental group (42 cases) and the control group (42 cases). Patients in the control group were placed in routine upper limb position, while patients in the experimental group were placed in upper limb pillow position. The data including systolic pressure, diastolic pressure, heart rate, saturation of blood oxygen were recorded on admission of operation room, completing placing body position, 30 minutes and 60 minutes after operation and after finishing the operation. The numbness/soreness of upper limbs and pressure injury rate was compared between the experimental group and the control group.Results:The rate of numbness/soreness of upper limbs were 2.4% (1/42) in the experimental group, 19.1%(8/42) in the control group, the differences were statistically significant (n χ2 value was 6.098, n P<0.05). The stage 1 pressure injury were 2 cases in the experimental group, stage 1 and 2 pressure injury were 6 cases and 2 cases, respectively in the control group, the differences were statically significant (n Z value was 2.039, n P<0.05).n Conclusion:Upper limb pillow position of the operation side can reduce postoperative complication of patients undergoing cerebellopontine angle tumor resection, but will not increase the risk of abnormal hemodynamic fluctuation.
