Continuous thoracic paravertebral analgesia after minimally invasive atrial septal defect closure surgery in pediatric population: Effectiveness and safety analysis.

Introduction: Lateral thoracotomy is replacing traditional median sternotomy for atrial septal defect (ASD) closure in children in order to improve cosmetic outcomes. Continuous paravertebral block has been described as an effective and safe analgesic technique in children. The aim of this study is to assess pain management by continuous perfusion of local anesthetic through a thoracic paravertebral catheter (PVC) in a pediatric population after thoracotomy closure of ASD, and its effectiveness in a fast-track program.
Methods: Descriptive cross-sectional study. Analgesic effectiveness, perioperative and safety-related data were analyzed in 21 patients who underwent thoracotomy closure of ASD with PVC. In the postoperative period, patients received continuous perfusion of bupivacaine 0.125% and fentanyl (1 mcg.ml-1) at 0.2 ml.kg-1.h-1 through the PVC.
Results: The median of mean pain scale score for each patient was 1.5. All patients were extubated in the operating theatre. No patient with PVC required opioid rescue. The median length of stay in the Pediatric Intensive Care Unit was 48 hours. There were 3 adverse events related to PVC: 1 due to malposition and 2 due to accidental removal. No other complications or cases of local anesthetic toxicity were recorded.
Conclusions: PVC provides effective, safe, opioid-saving analgesia in the postoperative period of ASD closure by thoracotomy in the context of a fast-track protocol.
