Impact of pulmonary artery catheter hemodynamic monitoring on post-operative morbidity and mortality in elective bentall procedures
2020
Introduction Because of debated effectiveness and safety, the perioperative use of pulmonary artery catheter (PAC) has decreased in cardiac surgery (1). However, PAC keeps some specifics indications in high risk cardiac surgery (2). This study evaluates the impact of perioperative PAC monitoring on postoperative morbidity and mortality after Bentall procedures. Methods We designed a single center retrospective observational study comparing patients undergoing Bentall procedure with or without perioperative CAP monitoring. Patients included had no major risk of hemodynamic complications (Left ventricular ejection fractions (LVEF) > 40%, no pulmonary arterial hypertension, no history of cardiac surgery). Primary endpoint was a composite criteria of postoperative morbidities and mortality defined by the occurrence of any the following: death in hospital, cardiac dysfunction (myocardial infarction or congestive heart failure), cerebral dysfunction (stroke or encephalopathy), renal dysfunction (acute kidney injury or dialysis), or pulmonary dysfunction (acute respiratory distress syndrome). Epidemiology of CAP use, others postoperative complications, biological markers (lactates, troponin), hemodynamic management and length of stay in intensive care unit (ICU) and hospital were also assessed. Results Among the 134 patients enrolled between 2012 and 2019, the primary endpoint occurred in 29 of 59 PAC patients vs. 17 of 75 patients without PAC (49.2%, 95% confidence interval (CI), 37-62, vs 22.7%, 95% CI, 15-33; P The PAC group had an increased risk of cardiac (22% vs 2.7%, P In multivariate logistic regression analysis, with independent factors (CAP use, length of cardiopulmonary bypass, EuroSCORE 2), CAP use was not associated with the occurrence of primary endpoint (adjusted odds ratio 2.07, 95% CI [0.9-4.7], P=0.08). Discussion In our study, a PAC was used in a highest risk group. The use of PAC was associated with increased postoperative mortality and morbidity in univariate but not in multivariate analysis. A randomized clinical trial is needed to clarify the link between CAP use and postoperative complications.
