Abstract:
Objective To investignte the effects of ambroxol on lung injury in children undergoing cardiac surgery with cardiopulmonary bypass (CPB).Methods Thirty-six ASA Ⅱ or Ⅲ children of both sexes aged≤8 yr,weighing≤25 kg undergoing repair of ventricular septal defect (VSD) under CPB were randomly divided into 3 groups (n=12 each):I control group (C);II low dose ambroxol group (2.25 mg/kg) (A,) and III moderate dose ambroxol group (4.50 mg/kg) (A2).Ambrexol was diluted with normal saline 10 ml and infused slowly after skin incision in group A1 and A2.In group C equal volume of normal saline(10 ml) was infused instead of ambroxol.Blood samples were taken from radial artery before skin incision,at 20 rain of CPB,20 rain after aortic unclamping,2 h and 6 h after temtination of CPB and 12 h after operation for determination of plasma MDA concentration and SOD activity and blood gas analysis.Respiratory index (RI) and pulmonary compliance (CL)were calculated.Results The plasma MDA concentration and RI were significantly lower while plasma SOD activity was significantly higher in group A2 than in group C and A1·CL was significantly higher in group A2 than in group C.Conclusion Ambroxol 4.50 mg/kg can attenuate lung injury in children undergoing cardiac surgery with CPB by decreasing lipid peroxidation.
