P50 IMPLEMENTATION OF PROTOCOLS FOR “ENHANCED RECOVERY AFTER CARDIAC SURGERY” IN AORTIC VALVE SURGERY

Abstract

Abstract Objective Although, the use of protocols for “enhanced recovery after surgery” (ERAS) have been associated with improved results in different surgical disciplines, no data are available for EARS in cardiac surgery, thus far. In the late 2016 a mutlidisciplinary ERAS program to treat patients who require AVR was implemented in our institution. The aim of this study was to assess safety and 30 day outcomes in patients receiving ERAS management. Methods To improve multidisciplinary ERAS program, our mini–invasive approach (Fig. 1), that goes beyond a small incision, includes: (i) mini–surgical access (ministernotomy–minithoracotomy), to reduce the traumatic impact, postoperative pain and to increase patient’s satisfaction; (ii) minimal invasive extracorporeal circulation system, to improve end–organ protection and decrease systemic inflammatory response; (iii) ultra fast–track anaesthesia, to decrease the rate of postoperative complications and assure better and earlier recovery (Fig. 2). Results Between September 2016 and December 2021, 600 consecutive patients (mean age 72 years, Euroscore II 1,62%) underwent isolated mini–AVR in our institution. UFT anaesthesia was used in 195 patients (32.5%) and MiECC in 173 (28.8%). All patients received a timely rehabilitation therapy (3–6 hours after surgery) and an early family contact in ICU. At 30 days, the overall mortality and stroke rates were 0,3% (n = 2) and 0,5% (n = 3), respectively. Respiratory insufficiency occurred in 16 pts (2,5%). Median blood loss at 12 hours was 174,5 cc; blood transfusions were reduced to minimum intraoperatively and avoided in 66% of patients. Twenty three patients (3,8%) received definitive pacemaker implantation. The median ICU and in–hospital lengths of stay were 1 and 6 days, respectively. Conclusions Findings from our study confirms that mini–AVR yields excellent clinical outcomes with very low mortality and morbidity rates. The implementation of ERAS protocol in patients undergoing mini–AVR demonstrated to be safe and was associated with promising results. Thus, by reducing surgical injury and promoting faster recovery, ERAS management may further enhance minimally invasive interventions.
