Abstract :

Transuretheral resection of prostate (TURP) for benign prostatic hyperplasia is frequently performed in elderly patients having cardiovascular limitations with various systemic diseases. Sixty patients classified in ASA I / II classes scheduled for TURP were studied. Patients were randomly allocated into study or control group. In our study, we found that 3μg of Dexmedetomidine added to 6mg of bupivacaine given intrathecally influences the sensory and motor block by shortening the onset time and prolonging the duration of absolute and effective analgesia without affecting the other parameters and complications of subarachnoid block. The onset of sensory block was faster in Study Group (D) with a mean value of 91.82±29.60 seconds as compared to a mean of 100.33± 11.29 seconds in the Control Group (S) and the difference was statistically significant. The motor block was also potentiated in the Dexmedetomidine group throughout the spinal anaesthesia. The duration of absolute and effective analgesia was notably prolonged in our study group with the mean duration being 173.00±22.49 and 255.500±26.10 respectively.
