Identifying independent predictor factors of failure of ultra-fast track (UFT) extubation and to compare in-hospital outcomes with UFT extubation versus fast track (FT) extubation after cardiovascular surgery in adults.
Retrospective analysis of 1,498 consecutive patients aged over 18 years-old undergoing cardiovascular surgery at a single institution. Between December 2014 and December 2016, FT extubation was used (N = 713) while, between December 2016 and December 2018, all patients were preoperatively considered suitable for UFT extubation (N = 785). In this instance, a standardized anaesthetic protocol was applied in all cases. The decision to not extubate in the operating room (OR) was based on intraoperative haemodynamic and ventilation.
Extubation in the OR was possible in 699 (89%) patients. Significant independent predictors factors of UFT extubation failure were: preoperative NYHA class III-IV, myocardial infarction within two days prior to surgery, preoperative intra-aortic balloon counterpulsation, urgent/emergent surgery, intraoperative transfusion of platelets and intraoperative inotropic and vasopressor support. UFT extubation was associated with lower rates of cardiovascular complications such as congestive cardiac insufficiency (OR: 1,57; 95% CI: 1,13-2,19; P = 0,008) and new-onset postoperatory atrial fibrillation (OR: 1,40; 95% CI: 1,06-1,86; P = 0,020). Patient extubated in the OR presented lower risk of overall complications, shorter intensive care unit stay and higher short-term survival, although, no statistically significance was found when performing the multivariate adjustment.
A routine immediate extubation in the OR following adult cardiovascular surgery is a feasible and safe practice, associated with low cardiovascular morbidity.
