摘 要:目的观察小剂量艾司洛尔在肥厚型梗阻性心肌病患者全身麻醉诱导时的临床应用效果。方法选取2014年1月至2015年12月在首都医科大学附属北京安贞医院择期行左心室流出道疏通术的肥厚型梗阻性心肌病患者56例,根据随机数字表法分为观察组和对照组,各28例。观察组麻醉诱导时给予艾司洛尔50μg/kg,对照组给予同等剂量的0.9%氯化钠注射液。记录并比较2组患者入室时(T0)、麻醉诱导后(T1)的心率、平均动脉压(MAP)、每搏输出量(SV)、体循环血管外周阻力(SVR)水平以及应用苯肾上腺素的情况。结果2组患者性别、年龄、身高、体质量及美国麻醉医师协会分级比较,差异均无统计学意义(均P〉0.05)。在T1时,2组心率、MAP、SV和SVR水平均低于T0时[观察组:(66±4)次/min比(78±7)次/min、(69±8)mmHg(1mmHg=0.133kPa)比(80±11)mmHg、(67±6)ml比(70±6)ml、(902±73)(Dyn·s)/cm^5比(1060±98)(Dyn·s)/cm^5;对照组:(68±5)次/min比(76±9)次/min、(64±7)mmHg比(76±13)mmHg、(62±5)ml比(66±8)ml、(869±89)(Dyn·s)/cm^5比(1008±121)(Dyn·S)/cm^5],应用苯肾上腺素比例高于T0时[观察组:3.6%(1/28)比0.0%(0/28);对照组:21.4%(6/28)比0.O%(0/28)];观察组MAP和SV水平均高于对照组,应用苯肾上腺素比例明显低于对照组,差异均有统计学意义(均P〈0.05)。结论全身麻醉诱导期给予患者小剂量艾司洛尔,能使肥厚型梗阻性心肌病患者的SV和血压保持相对稳定,有利于患者顺利度过全身麻醉诱导期。Objective To observe the clinical effect of low dosage esmolol applied in general anesthesia induction of hypertrophic obstructive cardiomyopathy. Methods Totally 56 patients undergoing left ventricular septal myectomy for hypertrophic obstructive cardiomyopathy were enrolled from January 2014 to December 2015 in Beijing Anzhen Hospital, Capital Medical University. The patients were randomly divided into observation group and control group, with 28 cases in each group. The observation group had esmolol 50 μg/kg during anesthesia induction; the control group had the same dosage of 0. 9% sodium chloride. Heart rate(HR), mean arterial pressure( MAP), stroke volume(SV) and systemic circulation vascular peripheral resistance(SVR) were recorded at the time of entering operating room ( T0 ) and after anesthesia induction ( T1 ). Usage of phenylephrine was recorded. Results Gender, age, body height, body mass and the grade of American Society of Anesthesiologists had no significant differences between groups at To ( P 〉 0.05 ). HR, MAP, SV and SVR at T1 were significantly lower than those at To in both groups[observation group: (66 ±4)times/rain vs (78 ±7)times/min,(69 ±8)mmHg vs ( 80 ± 11 ) mmHg, ( 67 ± 6) ml vs (70 ± 6) ml, (902 ± 73 ) ( Dyn · s)/cm^5 vs ( 1 060 ± 98 ) ( Dyn · s)/cm^5 ; control group : ( 68 ± 5 ) times/min vs (76 ± 9 ) times/min, ( 64 ± 7 ) mmHg vs ( 76 ± 13 ) mmHg, ( 62 ± 5 ) ml vs ( 66 ± 8 ) ml, ( 869 ± 89) ( Dyn · s)/cm^5 vs ( 1 008 ± 121 ) ( Dyn · s)/cm^5 ] ( P 〈 0.05 ). Use rates of phenylephrine at Tl were significantly higher than those at To in both groups[ observation group: 3.6% (1/28) vs 0. 0% (0/28) ; control group: 21.4% (6/28) vs 0. 0% (0/28) ] (P 〈 0. 05 ). At T1, MAP and SV in observation group were significantly higher than those in control group ; the use rate of phenylephrine in observation group was significantly lower
