RESUMEN
OBJECTIVE: Active chest tube clearance technology (ACT) systems were introduced to improve the patency of chest tubes and to reduce the potential complications associated with inadequate mediastinal blood drainage after cardiac surgical procedures. The purpose of this study is to assess the impact of ACT on the incidence of chest tube clogging, retained blood syndromes (RBS), re-exploration for bleeding, and the incidence of postoperative atrial fibrillation (POAF) after cardiac surgical procedures. METHODS: A database search was conducted using Medline, Embase, Cochrane Library, and Web of Science. Only articles comparing the use of ACT to conventional chest tube drainage after cardiac surgery were screened. Included articles were restricted to adult patients and English language only. RESULTS: Nine of the 841 articles screened were included in this review. Two studies were randomized controlled trials (RCT) and seven were observational studies. Pooled estimates showed RBS, surgical re-exploration rates, and POAF were significantly less common in the ACT group. CONCLUSION: Our meta-analysis suggests that the use of ACT may be beneficial in reducing the incidence of postoperative complications associated with inadequate drainage of mediastinal blood after cardiac surgery. However, more robust evidence is required to endorse these findings and support the routing use of ACT in clinical practice.
