Effect of parecoxib sodium on serum surfactant protein A and inflammatory response in elderly patients undergoing video-assisted thoracoscopic pneumonectomy / 临床麻醉学杂志

ABSTRACT

Objective To investigate the effects of perioperative parecoxib sodium on serum surfactant protein A and inflammatory response in elderly patients undergoing video-assisted thoracoscopic pneumonectomy,Methods Sixty-two ASA Ⅰ or Ⅱ elderly patients,aged 65-78 years,weighing 51-79 kg,scheduled for elective video-assisted thoracoscopic pneumonectomy under general anesthesia,were randomly divided into 3 groups0.3 mg/kg parecoxib sodium group (group P1,n=21),0.6 mg/kg parecoxib sodium group (group P2,n =21) and control group (group C,n =20).The patients were given intravenous parecoxib sodium of 0.3 mg/kg immediately before induction of anesthesia and at 12 h after operation in group P1,and also parecoxib sodium of 0.6mg/kg immediately before induction of anesthesia and at 12 h after operation in group P2,while the equal volume of normal saline was given in group C.Blood samples were taken from the central vein before the induction of anesthesia(T0),after operation(T1),12 h after operation(T2) and 24 h after operation(T3).The concentration of serum surfactant protein A (SP-A),TNF-α,IL-6 and IL-8 were determined by ELASA.The incidence of pulmonary complications at 72 h after operation were also recorded.Results Compared with T0,the concentration of serum SP-A,TNF-α,IL-6 and IL-8 increased significantly in all groups at T1-T3 (P＜0.05).Compared with C group,the concentration of serum SP-A,TNF-α,IL-6 and IL-8 in groups P1 and P2 decreased significantly at T1-T3 (P＜0.05),there were no significant differences between groups P1 and P2.The incidence of postoperative pulmonary complications had no statistically significant differences between the three groups.Conclusion Parecoxib sodium can significantly reduce the concentration of serum SP-A and alleviate the inflammatory response in elderly patients undergoing video-assisted thoracoscopic pneumonectomy.
