上肢动静脉内瘘对脉搏血氧饱和度监测结果的影响

Comparison on monitoring results of the limb saturation of pulse oxygen in arteriovenous fistula and non-arteriovenous fistula

目的探讨上肢动静脉内瘘对脉搏血氧饱和度(SpO_2)监测结果的影响。方法 2017年8月至2018年4月,南京医科大学第一附属医院老年血液净化中心行动静脉内瘘手术后的患者65例,分别同时监测其动静脉内瘘侧与非动静脉内瘘侧上肢的脉博血氧饱和度,并对监测结果进行比较。结果动静脉内瘘侧上肢SpO_2(97.72±2.02)%,非动静脉内瘘侧上肢SpO_2(96.54±1.77)%,动静脉内瘘侧上肢的SpO_2值高于非动静脉内瘘侧上肢的SpO_2值(P<0. 05)。结论动静脉内瘘术后患者在监测脉搏血氧饱和度过程中应尽量避免在术侧上肢监测,以保证所测数据准确,为观察病情变化提供可靠依据,以免延误对病情的观察。

Objective To discuss the difference of pulse oxygen saturation between limb with arteriovenous fistula and limb with non-arteriovenous fistula.Methods Sixty-five patients received arteriovenous fistula operation in Aged Blood Purification Center of the First Affiliated Hospital of Nanjing Medical University from August 2017 to April 2018 were extracted to participate the SpO 2 test simultaneously.Results The limb saturation of pulse oxygen in arteriovenous fistula is （97.72±2.02）%,and in non-arteriovenous fistula is （96.54±1.77）%,they are significantly different .Conclusions In the process of monitoring pulse oxygen saturation, patients with arteriovenous fistula should avoid monitoring the side of the upper limb as far as possible to ensure the accuracy of the measured data and reflect the patient s blood oxygen saturation correctly.
