内镜专用吸氧口垫的设计及应用

目的 设计内镜专用吸氧口垫,评价其临床应用效果。 方法 设计的内镜专用吸氧口垫包括口垫、鼻吸氧管、口腔吸氧管等7个部件。便利选取2021年1月—2月上海市某三级甲等医院内镜中心收治的120例因胆总管结石行内镜逆行胰胆管造影术的患者作为研究对象,采用随机数字表法分为试验组和对照组,每组各60例。试验组使用内镜专用吸氧口垫,对照组使用普通吸氧管及口垫。比较两组口垫佩戴时间、SpO₂波动差值、鼻导管移位率及医护人员满意度。 结果 试验组口垫佩戴时间为（20.58±2.43） s,对照组为（27.30±2.89） s,两组比较,差异具有统计学意义（t=-13.795,P<0.001）;试验组SpO₂波动差值为2.00%（1.00%,2.75%）,对照组为3.00%（2.00%,4.00%）,两组比较,差异具有统计学意义（Z=-4.332,P<0.001）;试验组鼻导管移位率为0,对照组为18.33%,两组比较,差异具有统计学意义（χ²=-12.110,P=0.001）;试验组医护人员满意度得分为（28.35±1.39）分,对照组为（26.48±1.56）分,两组比较,差异具有统计学意义（t=6.933,P<0.001）。 结论 内镜专用吸氧口垫佩戴方便,能减少患者术中SpO₂波动,降低鼻导管移位率,提高医护人员满意度及手术安全性。

Design and clinical application of a special oxygen mouth guard for endoscopy

Objective To design a special oxygen mouth guard for endoscopy and to evaluate its clinical application effects. Methods The designed special oxygen mouth guard comprises 7 elements（such as mouth pad,nasal and oral oxygen inhalation tubes）. A total of 120 patients with common bile duct stones undergoing endoscopic retrograde cholangiopancreatography at the endoscopy center of a tertiary hospital in Shanghai from January to February 2021 were included,and they were randomly divided into an experimental group and a control group,with 60 patients in each group. In the experimental group,the special oxygen mouth guard was used. In the control group,traditional oxygen tube and mouth guard were used. The wearing time,oxygen saturation（SpO₂） fluctuations,nasal catheter displacement rate and medical staff satisfaction were evaluated and compared between 2 groups. Results The wearing time in the experimental group was（20.58±2.43） s,while it was（27.30±2.89） s in the control group,and the difference was statistically significant（t=-13.795,P<0.001）. The SpO₂ value in the experimental group was 2.00%（1.00%,2.75%）,while it was 3.00%（2.00%,4.00%） in the control group,and the difference was statistically significant（Z=-4.332,P<0.001）. The nasal catheter displacement rate in the experimental group was 0,while it was 18.33% in the control group,and the difference was statistically significant（χ²=-12.110,P=0.001）. The score of medical staff satisfaction in the experimental group was（28.35±1.39）,while it was（26.48±1.56） in the control group,and the difference was statistically significant（t=6.933,P<0.001）. Conclusion The special oxygen mouth guard for endoscopy is easy to wear,and it can reduce the fluctuations in SpO₂ and nasal catheter displacement rate,and improve the medical staff satisfaction and safety of ERCP.
