雾化吸入小剂量氨溴索对开胸食道手术患者单肺通气时炎性反应的影响

目的 评价雾化吸入氨溴索对开胸食道手术患者单肺通气时炎性反应的影响.方法 择期行开胸食道手术患者60例,ASA分级Ⅰ或Ⅱ级,年龄39～64岁,体重50～85 kg,身高153～181cm.采用随机数字表法,将患者随机分为3组(n=20):对照组(C组)、静脉输注氨溴索组(IA组)和雾化吸入氨溴索组(AIA组).单肺通气前10 min,C组静脉输注生理盐水250 ml;IA组静脉输注氨溴索10mg/kg(用生理盐水稀释至250 ml);AIA组采用自制装置氧气驱动雾化吸入氨溴索4 ml(30 mg)+生理盐水2 ml,氧流量5～6 L/mim.于麻醉诱导后给药前1 min(T0)、单肺通气90 min(T,)和恢复双肺通气30 min(T2)时,采集桡动脉血样,采用双抗体夹心ELISA法测定血清TNF-α、IL-1β、IL-8和IL-10的浓度.结果 与T0时比较,各组T1和T2时血清TNF-α、IL-1β、IL-8的浓度升高,IL-10浓度降低(P＜0.05);与C组比较,LA组和AIA组T1和T2时血清TNF-α、IL-1β、IL-8的浓度降低,IL-10浓度升高(P＜0.05);IA组和AIA组各时点血清TNF-α、IL-1β、IL-8、IL-10的浓度差异无统计学意义(P＞0.05).结论 雾化吸入小剂量氨溴索可抑制开胸食道手术患者单肺通气导致的炎性反应,且与静脉注射大剂量氨溴索效果相似.

Abstract：

Objective To investigate the effects of inhaled aerosolized low dose ambroxol on the inflammatory response to one-lung ventilation ( OLV) in patients undergoing open-chest esophagus surgery. Methods Sixty patients with normal heart and lung function undergoing open-chest esophagus surgery were randomly divided into 3 groups ( n = 20 each): control group (group C) ; group IA received Ⅳ ambroxol 10 mg/kg after induction of anesthesia and group AIA inhaled aerosolized ambroxol 30 mg after induction of anesthesia. Arterial blood samples were taken after induction of anesthesia before ambroxol administration (T0, baseline) , at 90 min of OLV (T1 )and at 30 min after OLV (T2) for determination of plasma concentrations of TNF-α, IL-1β, IL-8 and IL-10 by ELBA.Results Plasma TNF-α, IL-1β, and IL-8 concentrations were significantly increased while plasma IL-10 concentration was significantly decreased at T1 and T2 as compared with the baseline at T0 in all 3 groups. Plasma TNF-α, IL-1β, and IL-8 concentrations were significantly lower and plasma IL-10 concentration was significantly higher at T1 and T2 in groups IA and AIA than in group C. Conclusion Both Ⅳ large dose ambroxol and inhaled aerosolized low dose ambroxol can inhibit the inflammatory response to OLV in patients undergoing open-chest esophagus surgery.
