Perioperative Anaesthesia Management During Minimally Invasive Surgery in Patients with Aortic Valve Diseases

Objective: Minimally invasive aortic valve replacement is a common procedures in practice. Our aim is to present our experiences on our anaesthesia applications during these operations. Methods: Upon the approval of the Hospital Ethics Committee, data of the patients that underwent minimal invasive aortic valve surgery between 1 January 2017 and 31 August 2017 were analysed retrospectively. Recorded details were age, gender, Body Mass Index (BMI), American Society of Anesthesiologists (ASA) classification, New York Heart Association classification (NYHA), Ejection Fraction (EF), Euroscore II, smoking history, accompanying diseases, cardiopulmonary bypass duration, aortic cross-clamping time, presence or absence of ventricular fibrillation, number of blood products given, time spent in intensive care unit, hospital stay, and intensive care mortality. Results: Results from a total of 22 patients were analysed. Median value for age was 55, minimum was 36, and maximum was 83. Of the patients, 59% was female, while 41% was male. It was found that 68% of the patients were classified as NYHA II and 32% fell into NYHA III. Euroscore II percentage was established as median 1.73 (minimum 0.79-maximum 2.75). Median cardiopulmonary bypass time was 120 minutes (minimum 73 minutes-maximum 165 minutes), and median cross-clamp time was 95 minutes (minimum 47 minutes-maximum 127 minutes). Median length of stay in intensive care unit was 15 hours (minimum 8 hours-maximum 23 hours), median hospitalization duration was established as 5 days (minimum 3 days-maximum 9 days). Conclusion: Anaesthesia applications in minimally invasive surgery carried out for aortic valve diseases predominantly include preoperative preparation, perioperative monitoring, and postoperative pain management.
