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

10. maj 2026 opdateret af: Salbia Bibi, PAEC General Hospital, Islamabad

Comparison of Hemodynamic Stability With 0.75 vs 0.5percent Hyperbaric Bupivacaine During Spinal Anesthesia in Cystoscopic Procedures:A Randomized Control Trial

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.

Detaljeret beskrivelse

OPERATIONAL DEFINITIONS:

Hemodynamic instability:This refers to systolic blood pressure heart rate shifts of 20% more or less from baseline value after spinal anesthesia.The hemodynamic instability will be evaluated both as a numerical change and categorical variable.

Hypotensin:A qualitative variable,defined as greater than 20% drop in baseline systolic blood pressure or systolic blood pressure of less than 90mmhg after spinal anesthesia.it will be recorded for each patient as present/absent.

Bradycardia:A qualitative variable,defined as heart rate below 60 beats per minute or greater than 20% drop in baseline heart rate after spinal anesthesia.it will be recorded for each patient as present /absent.

Hyperbaric bupivacaine:Local anesthetic mixed with dextrose to increase its density more than CSF.

0.75% hyperbaric bupivacaine is 7.5mg/ml. 0.5% hyperbaric bupivacaine is 5mg/ml. HYPOTHESIS:0.5% hyperbaric bupivacaine is better than 0.75% while undergoing cystoscopy under spinal anesthesia due to its better hemodynamic stability.
