目的 比较3 种预吸氧方式用于肥胖患者无痛胃肠镜的效果.方法 将2022 年2～12 月在我院进行无痛胃肠镜检查的120 例患者按随机数字表法分为3 组,每组40 人.A组给予常规鼻导管吸氧,B组给予面罩吸氧,C组给予持续正压通气,并对3 组患者不同时间点的心率(HR)、血压[收缩压(SBP)/舒张压(DBP)]、血氧饱和度(SPO2)、丙泊酚用量、麻醉时间、检查时间进行比较.结果 3 组患者预吸氧前(T0)、麻醉诱导前即刻(T1)、检查开始后 1 min(T2)、检查开始后 3 min(T3)、检查开始后5 min(T4)及完全苏醒后(T5)的HR、SBP/DBP比较,差异均无统计学意义(均P>0.05).3 组患者在T0、T1、T5 时的SPO2 比较,差异无统计学意义(P>0.05);C组患者在T2、T3、T4 时的SPO2 高于B组和A组,差异均有统计学意义(均P<0.05);B组患者在T2、T3、T4 时的SPO2 高于A组,差异有统计学意义(P<0.05).3 组患者的丙泊酚用量、麻醉时间、检查时间比较,差异均无统计学意义(均P>0.05).结论 肥胖患者无痛胃肠镜检查时给予持续正压通气预吸氧的效果良好,可有效调控患者SPO2,稳定生命体征.
Abstract
Objective To compare the effect of three kinds of preoxygenation for painless gastroenteroscopy in obese patients.Methods 120 patients who underwent painless gastroscopy in our hospital from February to December 2022 were randomly divided in-to three groups using a random number table method,with 40 patients in each group.Group A was given routine nasal catheter oxygen inhalation,group B was given mask oxygen inhalation,and group C was given continuous positive pressure ventilation.The Dim sum rate(HR),blood pressure[systolic blood pressure(SBP)/diastolic blood pressure(DBP)],oxygen saturation(SPO2),propofol dosage,anesthesia time,and examination time of the three groups were compared at different times.Results There was no statistically signif-icant difference in HR and SBP/DBP among the three groups of patients before pre oxygenation(T0),immediately before anesthesia in-duction(T1),1 minute after examination(T2),3 minutes after examination(T3),5 minutes after examination(T4),and after com-plete awakening(T5)(P>0.05).There was no statistically significant difference in SPO2 between the three groups of patients at T0,T1,and T5(P>0.05);The SPO2 of Group C patients at T2,T3,and T4 was higher than that of Group B and Group A,with statistical significance(P<0.05).The SPO2 of Group B patients at T2,T3,and T4 was higher than that of Group A,with statistical significance(P<0.05).There was no statistically significant difference in the dosage of propofol,anesthesia time,and examination time among the three groups of patients(P>0.05).Conclusion Continuous positive pressure ventilation with pre oxygenation during painless gas-troscopy in obese patients has a good effect,which can effectively regulate the patient's SPO2 and stabilize vital signs.
