Capillary leak syndrome (CLS) is an urgent problem in postoperative patients, is challenging to diagnose early, and has a poor prognosis. We investigated a quick and convenient diagnostic indicator of secondary CLS in children after cardiopulmonary bypass (CPB).
We conducted this single-center, observational, prospective study in the Department of Critical Care Medicine at the Children's Hospital of Chongqing Medical University. All the data were collected within 24 h after cardiopulmonary bypass (CPB). The secondary CLS risk factors were determined using univariate and multivariate logistic regression analysis, and the cut-off point of secondary CLS was found by receiver operating characteristic (ROC) analysis.
Our study included two hundred four pediatric patients in the PICU after cardiopulmonary bypass (CPB). 42.65% (87/204) of patients were diagnosed with secondary CLS. The incidence of acute kidney injury (AKI) was 36.76% (75/204), and the mortality was 5.39% (11/204). Logistic analysis indicated that a pulmonary exudation on chest radiograph, a high thoracic fluid content (TFC) and a higher vasoactive inotropic score (VIS) were independent risk factors for secondary CLS [odds ratio [OR] 23.62, 95% confidence interval [CI] 7.20-90.41, < 0.001; OR 1.08, 95% CI 1.02-1.16, = 0.010; OR 1.06, 95% CI 1.01-1.14, = 0.049; respectively]. According to the ROC analysis, the cut-off point for the TFC was 52 (Ω).
The TFC plays a key role in the early prediction of secondary CLS in children after CPB, and this novel indicator may help clinicians initiate intensive treatment as early as possible.
毛细血管渗漏综合征（CLS）是术后患者面临的一个紧迫问题，早期诊断具有挑战性，且预后较差。我们研究了一种快速便捷的诊断小儿体外循环（CPB）后继发性CLS的指标。
我们在重庆医科大学附属儿童医院重症医学科进行了这项单中心、观察性、前瞻性研究。所有数据均在体外循环（CPB）后24小时内收集。使用单因素和多因素逻辑回归分析确定继发性CLS的危险因素，并通过受试者工作特征（ROC）分析找到继发性CLS的截断点。
我们的研究纳入了204例体外循环（CPB）后入住儿科重症监护病房（PICU）的患儿。42.65%（87/204）的患者被诊断为继发性CLS。急性肾损伤（AKI）的发生率为36.76%（75/204），死亡率为5.39%（11/204）。逻辑分析表明，胸部X线片上的肺部渗出、高胸液含量（TFC）和较高的血管活性药物评分（VIS）是继发性CLS的独立危险因素[比值比（OR）23.62，95%置信区间（CI）7.20 - 90.41，P < 0.001；OR 1.08，95% CI 1.02 - 1.16，P = 0.010；OR 1.06，95% CI 1.01 - 1.14，P = 0.049；分别]。根据ROC分析，TFC的截断点为52（Ω）。
TFC在小儿体外循环（CPB）后继发性CLS的早期预测中起关键作用，这一新型指标可能有助于临床医生尽早启动强化治疗。
