Effect of Ambroxol on Contents of PMN,TNF-?,IL-6 and IL-8 in Bronchoalveolar Lavage Fluid after Closed Circuit Anesthesia in Infants / 医学研究杂志

ABSTRACT

Objective To investigate the effect of ambroxol administered before surgery on contents of PMN,TNF-?,IL-6 and IL-8 in bronchoalveolar lavage fluid after closed circuit anesthesia in infants.Methods 40 infants who practiced selective orthopedics or abdominal operations were randomly divided into ambroxol group (group A) and control group (group B). Two days before operation,infants in group A and group B were administed ambroxol 0.3 mg/kg or 0.9 normal saline 10 ml through intravenous injection three times per day,respectively .The last single dose was administered before anesthesia induction.The bronchoalveolar lavage fluid of intants were collected immediately after tracheal intubation(T1) and before tracheal extubation(T2),respectively.Interleukin-6 and interleukin-8 in the bronchoalveolar lavage fluid were determined by enhancement solid-phase enzyme immunoassay action(EASIA),and TNF-? in the bronchoalveolar lavage fluid by euzymelinked immunosorbent assay (EIA).The numbers of polymorphonuclear neutrophils in the bronchoalveolar lavage fluid were examined. The contents of PMN,TNF-?,IL-6 and IL-8 in two groups were compared .The time of analepsia and complications of respiratory tract were observed after operation.Results Compared with group A, the contents of PMN,TNF-?,IL-6 and IL-8 in BALF collected at T2 were significant higher in group B (P
