喉罩通气对全麻下腹腔镜胆囊切除术患者心血管应激的影响

Effect of laryngeal mask airway for cardiovascular stress in general anesthesia on patients with laparoscopic cholecystectomy

目的探讨喉罩通气对全麻下腹腔镜胆囊切除术(LC)患者心血管应激的影响。方法 64例全麻下行LC患者随机分为对照组和喉罩组,比较两组患者入室后(T0)、麻醉诱导后(T1)、喉罩置入或气管插管即刻(T2)、气腹后(T3)、拔除喉罩或气管导管前即刻(T4)和拔除喉罩或气管导管后即刻(T5)血流动力学变化及不良反应发生率。结果两组患者T0、T1、T3、T4时间点SBP、DBP、HR及SpO2差异无统计学意义,T2及T5时间点喉罩组SBP、DBP、HR高于对照组。麻醉不良反应发生率对照组低于喉罩组。结论喉罩通气能减少全麻下LC术中心血管应激反应。

Objective To investigate the effect of laryngeal mask airway for cardiovascular stress in general anesthesia on patients with laparoscopic cholecystectomy. Methods Sixty-four patients who would take laparoscopic cholecystectomy （LC） were selected and randomly divided into control group and laryngeal mask group. Change of haemodynamics were contrasted after getting in operating room （To）, and anesthesia induction （TI）, when inserting laryngeal mask airway and tracheal intubation （T2）, after artificial pneumoperitoneum （T3）, before and after pulling out laryngeal mask airway and tra cheal intubation （T4 and Ts）. Adverse reaction were contrasted in convalescent period between control group and laryngeal mask group. Results The level of SBP, DBP, HR and SpO2 was identical between control group and laryngeal mask group in To, Tl, T3 and T4. The level of SBP, DBP, HR were lower in laryngeal mask group than in T2 and Ts. incidence rate of restlessness in convalescent period was lower in laryngeal mask group than in control group. Conclusion Laryngeal mask airway anesthesia could decrease cardiovascular stress in general anesthesia on patients with LC.
