Analysis about strategies on lung protection of ventricular septal defect infants during perioperation / 中华胸心血管外科杂志

ABSTRACT

Objective Approach to safe and effective lung protection strategies on ventricular septal defect infants during perioperation.Methods There were 4 groups as blank control group,ambroxol group,methylprednisolone group and ulinastatin group.We tried to find a safe and effective stratege on lung protection by comparing each other on the respiratory function indexes and inflammation biomarkers.Results Postoperation of VSD repair,respiratory function indexes such as Ppeak,oxygenation index inspiratory resistance and mechanical ventilation time were significantly different (P ＜ 0.05) among the 4 groups.The inflammation biomarkers such as WBC,CRP and PCT had no differences the first day(P ＞0.05),and were statistically significant the third day (P ＜ 0.05).Conclusions Ambroxol,methylprednisolone and ulinastatin all are effective drugs for lung protection.Considering about the clinical curative effect and side effects,ambroxol is more safe and effective relatively.
