Abstract

Objective: To evaluate the criteria, use and complications of temporary epicardial pacemakers after pediatric open heart surgery. Material and methods: A prospective non-randomised study was conducted on 326 consecutive patients. Data was collected on admission to the Intensive Care Unit arrival, at 24 hours and when the leads were removed. SPSS-11.5 program was used for statistical analysis, with χ2 to compare discrete variables. Results: Leads were implanted in 228 (69.9%) children, and 30 (9.2%) actually used them. No untoward effects were recorded on removal. More than two-thirds (156, 68.4%) of the patients had the leads removed before 48 hours, and in 10 cases they remained for more than 7 days. Univariate analysis failed to show any correlation between diagnosis and use of pacemaker. Ventricular septal defect, atrio-ventricular septal defect, and Fallot (as a group) did not reach statistical significance (P=.148). Conclusions: Pacemaker use relies on surgeon discretion. A temporary epicardial pacemaker after open heart surgery was used by 9.2% of patients in this study. Stable sinus rhythm in the first 48 hours predicts sinus rhythm thereafter, allowing safe removal of leads in Intensive Care Unit. The cluster of ventricular septal defect, atrio-ventricular septal defect, and Fallot does not reach sufficient statistical significance to predict the use of pacemaker in the post-operative period (P=.148). Longer series are needed to set predictors of temporary pacemaker use after open heart surgery.
