1、挛,使痰液顺利排出,改善患儿缺氧症状,促进其临床转归7。由于病原菌感染,患儿机体炎症因子水平升高,CRP 是肝细胞产生的急性时相蛋白,其水平变化与机体发生损伤、感染相关8。PCT 是降钙素的前体物由肝脏产生,当机体受细菌、真菌感染时,其水平显著上升,能反映炎症的水平。氨溴索能增强抗菌药物气道浓度,对细菌或病毒滋生有抑制作用;布地奈德可与呼吸道上皮部位的糖皮质激素受体结合,可阻断炎性介质、过敏活性递质释放,发挥快速的抗炎效应,抑制呼吸道毛细血管通透性,两者联用能够有效改善局部炎症9。IgA、IgM、IgG 与机体体液免疫相关,IgM 在感染后出现较早,具有溶血溶菌的效果;IgA 是主要存在于呼吸
2、道分泌液、唾液等外分泌液中,能够抑制病原菌的黏附的作用;IgG 是由淋巴结及脾脏产生,在感染后出现时间较晚,但亲和力高、作用时间长,三者在中和毒素、抗感染过程中均发挥重要作用。本研究显示,观察组 CRP、PCT 水平均低于对照组,观察组 IgA、IgM、IgG水平高于对照组,提示联合治疗对患者患儿炎症因子水平、免疫功能的改善效果优于单一布地奈德雾化,有利于其病情恢复。治疗期间,两组不良反应发生率分别为 9.68%、7.53%,且比较无明显差异,提示布地奈德雾化联合氨溴索治疗不会增加患儿的不良反应发生率。综上,布地奈德雾化联合氨溴索治疗小儿支气管肺炎疗效优于单一布地奈德雾化,对患儿临床症状、炎症
