Comparison of Hemodynamic Stability With 0.75percent and 0.5percent Hyperbaric Bupivacaine During Spinal Anesthesia in Cystoscopic Procedures

Starting soon · Phase 4

Conditions studied: Cystoscopy

In brief

Purpose:The aim of this study is to determine the intrathecal Bupivacaine concentration(0.5% vs 0.75%) with better anesthesia and little hemodynamic disturbance during cystoscopic procedures.In comparing these bupivacaine concentrations ,the result would be expected to enhance safer spinal anesthesia practices ,minimizing the use of vasopressors in urological surgeries.OBJECTIVE:To compare and analyze the frequency and average chages of post spinal hemodynamic instability in terms of hypotension and bradycardia with 0.75% hyperbaric bupivacaine and 0.55 hyperbaric bupivacaine in patients presenting for cystoscopic procedures.
