Predictors for intraoperative heart failure in children undergoing foreign-body removal

This study aimed to determine the predictors for intraoperative heart failure (HF) in children undergoing foreign-body removal. The clinical data of all children with tracheobronchial foreign-body aspiration admitted to the First, Second, and Fourth Affiliated Hospitals of Harbin Medical University between January 1996 and September 2018 were analyzed. The variables with significant difference in univariate analysis were involved into the multivariate Logistic model to determine the predictors for intraoperative tachycardia. In total, 300 tracheobronchial foreign-body aspiration children were eligible for the study, among whom 60 cases (20%) suffered from HF during the operation. Between the children HF and those without HF, the differences were pronounced in history of allergy, history of asthma, congenital heart disease, preoperative respiratory infection, retention time of foreign bodies, duration of operation, and poor anesthesia effect (P < .05). Multivariate analysis results showed that history of allergy (odds ratio [OR]: 1.395, 95% confidence interval [95% CI]: 1.202-1.620, P < .001), congenital heart disease [OR: 3.071, 95% CI: 1.141-8.264, P < .001], preoperative respiratory infection [OR: 2.345, 95% CI: 1.027-5.355, P = .043], retention time of foreign bodies [OR: 1.013, 95% CI: 1.010-1.016, P < .001], duration of operation [OR: 1.030, 95% CI: 1.027-1.033, P < .001], and poor anesthesia effect [OR: 1.125, 95% CI: 1.117-1.134, P < .001] were identified as the influencing factors for intraoperative HF. In conclusions, for children undergoing foreign-body removal, history of allergy, congenital heart disease, preoperative respiratory infection, retention time of foreign bodies, duration of operation, and poor anesthesia effect are associated with an increased risk of intraoperative HF.
