RESUMO
Objective To analyze the risk factors associated with multiple organ dysfunction syndrome (MODS) in children after cardiopulmonary bypass (CPB).Methods Between Jan 2001 and Dec 2010,1 899 patients undergoing open heart surgery were reviewed retrospectively according to the presence or absence of MODS.Univariate and multivariate logistic regression analysis were used to identify the risk factors.Results Thirty-five patients (1.84％) developed MODS,the mortality for MODS was 51.43％ (18/35).Univariate risk factors included complex congenital heart disease,perioperative unexpected events,CPB time,aortic cross-clamping time,mechanical ventilation time,and postoperative spsis.Multivariate logistic regression analysis identified that complex congenital heart disease,perioperative unexpected events,CPB time ＞ 180 min,postoperative spsis were risk factors.Conclusion The results suggest that the patients with MODS risk factors described above need more careful peri and post operative surveillance and preventive management.
