Résumé
Aim of the Study: to assess the merits and demerits of posterior pericardial drainage in patients undergoing heart surgery
Materials and Methods: a systematic review and meta-analysis of observational studies and randomized controlled trials was conducted. We searched for relevant trials in the Cochrane Library, MEDLINE [from 1980], Embase from 1970 the Transfusion Evidence Library from 1980, and ongoing trial databases; all searches current to 30 September 2017
Results: the search yielded sixteen randomized controlled trials which included 2755 patients. Results revealed that Posterior pericardial drainage was associated with a significant 90% reduction of the odds of cardiac tamponade versus the control group: [OR 95% confidence interval] 0.13; P < 0.001. The ORs of death or cardiac arrest were significantly decreased by approximately 50% in the posterior pericardial drainage group compared to controls: OR [95% CI]: 0.47, P = .028; I2 = 0%
Conclusion: posterior pericardial drainage has been reported in the literature to significantly reduce the prevalence of early pericardial effusion as well as cardiac tamponade. A significant enhanced survival rate was recorded postcardiac surgery
