Comparison Of Single-Shot Spinal Anaesthesia and Continuous Spinal Anaesthesia In Patients Undergoing Open Prostatectomy

Abstract Aim:In this study, in patients undergoing open prostatectomy, comparison of sin-gle shot spinal anesthesia (SSA) and continuous spinal anesthesia (CSA) methods in termsof hemodynamics, quality of anesthesia, and complications was aimed. Material and Methods:42 patients (ASA I-III) over 50 years of age were randomly divided into two groups. Patients in group SSA (n=21) received 3.5 ml of hyperbaricbupivacaine 0.5%. Patients in group CSA (n=21) received1.5 ml hyperbaric bupivacaine 0.5% intrathecally. Sensorial blockade reached at thoracal 10 (T-10) and at Bromage Scale 3, the first with 15 minutes and the latter doses with 5 minutes intervals 0,5 mL, hyperbaric bupivacaine %0,5 was administered. Throughout the operation patient’s non-invasive arterial blood pressure, heart rate, decrease in blood pressure 25%, amount of blood loss, additional fluid needs, vasoactive medication needs, atropine needs, additional local anesthetics needs, were recorded. Blocade performing time, the time full motor blockade and sen-sorial blockade’s reached at T-10, two segments regression time, resolution of motor and sensorial blockade time wererecorded. Results:In CSA Group performing of anesthesia time,full motor blockade achievement time needed and the timeneeded for sensorial blockade to reach T-10 was long, twosegment regression time, motor sensorial blockade time were short. In SSA group hypotension, additional fluid need andephedrine need were higher than CSA group. Conclusion: In CSA Group by low dose local anaest-hetic, appropriate anesthesia level and better hemodynamicstability were achieved. When CSA performed properly tosuitable patients, it is a reliable and effective technique
