经喉罩全凭七氟醚吸入麻醉在老年患者支气管镜检查术中的应用效果及安全性观察

Observation of effects and safety of laryngeal mask airway combined with Sevoflurane inhalation anesthesia in elderly patients tested by bronchoscopy

目的:观察经喉罩全凭七氟醚吸入麻醉在老年患者支气管镜检查术中的应用效果及安全性。方法:选取68例接受支气管镜检查术老年患者,根据麻醉方法不同分为观察组(37例)和对照组(31例)。观察组患者给予经喉罩全凭七氟醚吸入麻醉;对照组患者给予丙泊酚静脉麻醉。对比两组患者的麻醉优良率、心率(HR)、收缩压(SBP)、舒张压(DBP)、血氧饱和度(SO2)、苏醒时间和不良反应发生率。结果:观察组患者的优良率为97.30%(36/37),对照组为93.55%(29/31),两组患者比较差异无统计学意义(x2=0.025,P>0.05);放置喉镜后、拔除喉镜时,观察组患者的SBP、DBP、HR水平低于对照组,差异具有统计学意义(P<0.05);观察组患者的苏醒时间短于对照组,差异具有统计学意义(t=3.839,P<0.05);观察组患者的不良反应发生率低于对照组,差异具有统计学意义(t=4.648,P<0.05)。结论:经喉罩全凭七氟醚吸入老年人支气管镜检查术中的麻醉优良率与丙泊酚静脉麻醉相当,但其他临床安全性指标均优于丙泊酚静脉麻醉。

Objective To observe effects and safety of laryngeal mask airway （ LMA） combined with Sevoflurane inhalation anesthesia in elderly patients tested by bronchoscopy. Methods ： 68 elderly patients receiving bronchoscopy were divided into obser^^a- tion group （ n = 37） and control group （ n = 3 1 ） according to the different anesthesia methods. The observation group was give the LMA combined with Sevoflurane inhalation anesthesia, while the control group was given Propofol intravenous anesthesia. The excellent and good rates of anesthesia, heart rates （HR） , systolic blood pressure （SBP） , diastolic blood pressure （ DBP） , blood oxygen saturation （S〇2 ） , recovery time, and adverse reactions incidences of the two groups were compared. Results ： The excellent and good rates of the observation group and the control group were 97.30% （36/37） and 93. 55% （29/31） , respectively, and the difference was not statistically significant （x2 =0.025, P〉0.05）. At removal of the laryngoscope, the SBP, DBP, HR and levels of the observation group were lower than those of the control group, and the differences were statistically significant （P〈0.05）. The recover^^ time of the obser-vation group was shorter than that of the control group, and the difference was statistically significant （t = 3.839, P〈0. 05 ）. Moreover, the incidence of adverse reaction in the observed group was lower than that of the control group, and the difference was statistically sig-nificant （t =4.648, P〈0. 05）. Conclusions： The laryngeal mask combined with Sevoflurane inhalation anesthesia used in the elderly bronchoscopy is as effective as Propofol intravenous anesthesia, but the other safety indicators are better.
