摘　　要：目的探讨深呼吸预吸氧预防麻醉药引起呼吸抑制导致的血氧饱和度（SpO2）下降的实用价值。方法选择我院腔镜科无痛胃镜受检者60例，随机分深呼吸组和对照组各30例。深呼吸组于麻醉给药前60s做深呼吸8-10次，对照组在麻醉给药前不做特殊处理，保持自然呼吸。两组麻醉方法相同。结果深呼吸组受检者有一过陛SpO2下降，但是出现SPO2下降的时间点较对照组晚，时间后移且均能自行缓解，需要托下颌辅助2例；对组SpO2下降（SpO2〈95％）例数多于深呼吸组，SpO2下降幅度较大，需要托下颌辅助4例，SpO2〈90％1例，平卧后面罩给O2缓解。结论在无痛内镜麻醉中，深呼吸预处理、吸氧去氮可以有效地预防和改善麻醉药对呼吸抑制程度，提高受检者的安全性。Objective To discuss the value ofbathypnea pretreatment to prevent the decrease of blood oxy- gen saturation （SPOt） caused by anesthetics-induced apnea. Methods Sixty patients undergoing endoscopy are ran- domly arranged into two groups, with 30 patients in each group. In the bathypnea pretreatment group, 8-10 times of deep breathing was performed 60 s before anesthesia. In the control group, patients were requested to breathe naturally. Results Patients in the bathypnea pretreatment group experienced a transient SpO2 decrease, but this phenomenon oc- curred later than that in the control group and could always ameliorated spontaneously. Jaw-lift is required in 2 patients in the bathypnea pretreatment group. More patients in the control group experienced SpO2 decrease （SpO~〈95%） than that in the Bathypnea pretreatment group. The SpO2 decreases were more profound, and 4 patients require jaw-lift. There was one patient with SpO2 less than 90%, which ameliorated after O2 inhalation through face mask. Conclusion Bathypnea pretreatment can effectively prevent and improve anesthesia-induced apnea in anesthetized endoscopy.
