内镜专用吸氧口垫的设计及应用

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

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、SpO_(2)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SpO_(2)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(χ^(2)=-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SpO_(2)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。

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(SpO_(2))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 SpO_(2) 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(χ^(2)=-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 SpO_(2) and nasal catheter displacement rate,and improve the medical staff satisfaction and safety of ERCP.
