A randomized controlled study of oral⁃nasal oxygen supply mouth guard in painless gastroscopy for snoring patients

摘要:

目的 评价一体式口鼻供氧口垫在鼾症患者无痛胃镜检查中的应用效果。方法 选取2022年7月同济大学附属东方医院两个内镜中心接受无痛胃镜检查的鼾症患者作为研究对象，随机数字表法随机分为观察组（使用一体式口鼻供氧口垫）和对照组（使用普通口垫及鼻吸氧管）。比较2组供氧设备佩戴用时及移除用时、最低脉搏血氧饱和度（pulse oxygen saturation， SpO2）、低氧血症发生率、医护人员满意度。结果 观察组（n=40）供氧设备佩戴、移除用时分别为（11.63±0.84）s和（5.33±0.76）s，分别低于对照组（n=47）的（14.91±1.21）s（t=-14.463，P<0.001）和（10.38±0.80）s（t=-30.095，P<0.001）。观察组供氧设备佩戴满意度评分、最低SpO2、供氧设备移除满意度评分、麻醉师满意度评分分别为（9.80±0.61）分、（96.70±3.42）%、（9.75±0.67）分、（9.20±1.42）分，分别高于对照组的（7.70±0.93）分（t=12.209，P<0.001）、（94.06±3.72）%（t=3.417，P=0.001）、（7.96±0.98）分（t=9.803，P<0.001）、（8.13±1.35）分（t=3.615，P=0.001）。观察组低氧血症发生率略低于对照组［10.00%（4/40）比14.89%（7/47），χ2=0.130，P=0.718］，内镜医师满意度评分高于对照组［（9.30±0.97）分比（9.02±1.31）分，t=1.112，P=0.269］。结论 一体式口鼻供氧口垫佩戴及移除方便，能减少鼾症患者无痛胃镜检查中的SpO2波动，提高医护人员满意度，具有较好的临床应用价值。

Abstract:

Objective To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients. Methods The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group (n=40), which were lower than those in the control group (n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists'' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.
