Abstract

Catheter relater bladder discomfort (CRBD) is a common phenomenon in catheterised patients after endourological surgeries. Aims & Objective:The aim of our study is to study the effect of intrathecal dexmeditomidine as an adjunct to spinal anaesthesiaon incidence and severity of catheter related bladder discomfort in post-operative period. Materials and Methods This study included all American Society of Anesthesiologist (ASA) grade I/II patients (18–40 years) who underwent percutaneous nephrolithotomy (PCNL) for renal calculi; and had, no previous history of dysuria or other urological disorders between August 2017 and July 2018. The patients were randomized in two groups based on computer generated random number table. Group I (control group) received 3ml levobupivacaine 0.5% in 0.5ml normal saline and Group II received 3ml levobupivacaine 0.5%+ 2.5 mcg dexmedetomidine in 0.5 ml of normal saline. Bladder discomfort was assessed at 8, 10 and 12 hours after induction of anaesthesia. Results & Conclusion: The incidence of CRBD after 8 hours of induction was higher in control group compared to dexmedetomidine group (56% vs 18% P <0.01). Our study gives primitive conclusive evidence that intrathecal dexmedetomidine as a spinal anaesthesia adjunct may be a viable option in reducing the incidence and severity of CRBD.
