Despite good results in neonates, extracorporeal membrane oxygenation (ECMO) is less well accepted in pediatric patients. Older children frequently undergo ECMO for severe bacterial, viral, or aspiration pneumonia and many have coexisting systemic sepsis. We reviewed data from a national registry to study the influence of sepsis on survival from ECMO.
Six hundred fifty-five patients (aged 2 weeks to 17 years) with respiratory failure treated with ECMO were divided into two groups by the presence (n = 76) or absence (n = 579) of sepsis. Groups were compared by univariate analysis and by multivariate logistic regression that considered 10 additional pre-ECMO variables (age, sex, weight, arterial blood gas results, ventilator parameters, and renal failure).
By univariate analysis, survival was lower in septic children (36.8% versus 51.6%; p < 0.02). However, by multivariate analysis, sepsis was not an independent survival predictor (odds ratio, 0.578; 95% confidence interval, 0.288-1.162; p = 0.12). The ECMO complications predicted by the presence of sepsis included (1) seizures, (2) other neurologic complications, and (3) infection at other sites (all p < 0.05).
Systemic sepsis does not independently influence survival in pediatric ECMO. This therapy should not be withheld solely because of sepsis, although neurologic complications may occur more frequently.
尽管体外膜肺氧合(ECMO)在新生儿中取得了良好效果,但在儿科患者中接受度较低。大龄儿童常因严重细菌、病毒或吸入性肺炎接受ECMO治疗,且许多患者并存全身性败血症。我们回顾了来自国家登记处的数据,以研究败血症对ECMO存活情况的影响。
655例接受ECMO治疗的呼吸衰竭患者(年龄2周至17岁),根据是否存在败血症分为两组(存在败血症组n = 76,无败血症组n = 579)。通过单因素分析和多因素逻辑回归比较两组,多因素逻辑回归考虑了另外10个ECMO前变量(年龄、性别、体重、动脉血气结果、呼吸机参数和肾衰竭)。
单因素分析显示,败血症患儿的存活率较低(36.8%对51.6%;p < 0.02)。然而,多因素分析显示,败血症不是独立的存活预测因素(优势比,0.578;95%置信区间,0.288 - 1.162;p = 0.12)。败血症存在所预测的ECMO并发症包括(1)癫痫发作,(2)其他神经系统并发症,以及(3)其他部位感染(均p < 0.05)。
全身性败血症不会独立影响儿科ECMO的存活情况。尽管神经系统并发症可能更频繁发生,但不应仅因败血症而不进行这种治疗。
