PurposeThis study was performed in order to evaluate effectiveness of controlled hypotension decreasing blood lose in transthoracic esophageal resection.Patients And MethodsThirty-six patients were enrolled in this randomized study. The patients were divided in to two groups. We used controlled hypotension induced by thoracic epidural anaesthesia for the group T (n=18/50%). For the group K (n=18/50%) we used only endotracheal anesthesia. The median arterial pressure was about 50 mmHg in group T and 80-110 mmHg in group K. We investigated intra-operative and post-operative blood loss, the average operating time, opioid and inhaled anesthetic use and stay in intensive care unite.ResultsThe intra-operative blood loss was less for 45.7% in group T than in group K but post-operative blood loss was the same in groups. The mean operation time was 14.2% shorter in group T. We used 80% less fentanyl and 43% less inhaled anesthetics in group T. The stay in intensive care unit was 2.6 days in group T and 3.9 in group K. There were no significant complications caused by controlled hypotension.ConclusionWe conclude that controlled hypotension is an effective method to decrease blood loos and blood transfusions. It creates better conditions for surgery and reduces operation time. There were no serious cardiac, neurological and renal intra-operative and post-operative complications resulting from the use of controlled hypotension.
