目的:分析小儿先天性心脏病术后感染的相关因素,为临床用药、护理及治疗提供依据。方法:对2008年9月～2009年5月期间,进行先天性心脏病手术、满足入选条件的患儿346人,进行回顾性分析,根据发生感染与否将患儿分为感染组(39人)和对照组(307人);将可能的危险因素先进行单因素分析,在此基础上进行多因素Logisitic回归分析。结果:两组患儿在年龄、术前住院时间、体重等17个指标上的差异有统计学意义(P<0.05);多因素Logisitic回归分析表明肺动脉高压、恢复室停留≥120 h、体外循环时间≥120 min、机械通气时间≥120 h、频繁的吸痰是发生感染的独立危险因素。结论:多种因素导致先心病患儿术后发生感染,必须采取综合性的预防措施才能有效控制。
Objective: To analyze the related factors of postoperative infection of congenital heart disease in children and provide the basis for clinical medication, nursing and treatment. Methods: From September 2008 to May 2009, 346 children with congenital heart disease undergoing congenital heart disease were enrolled in this study. Retrospective analysis was performed to divide the children into infection group (39 ) And control group (307 patients). The possible risk factors were analyzed by univariate analysis and multivariate Logisitic regression analysis was used to analyze the risk factors. Results: There were significant differences in age, preoperative length of hospital stay, body weight and other 17 indexes between the two groups (P <0.05). Multivariate logistic regression analysis showed that pulmonary hypertension, recovery room stay ≥120 h, cardiopulmonary bypass Time ≥ 120 min, mechanical ventilation ≥ 120 h, frequent suction is an independent risk factor for infection. Conclusion: Various factors lead to postoperative infection in children with congenital heart disease, and comprehensive preventive measures must be taken to control them effectively.
