BACKGROUND We wanted to compare the efficacy of motor and sensory blockade in lower limb and lower abdomen surgeries achieved by ropivacaine-fentanyl and bupivacainefentanyl combinations administered intrathecally. METHODS A prospective, randomized [block randomization], interventional, comparative study was conducted on 116 American Society of Anesthesiologists physical status I – II patients. They were randomly divided into two groups of 58 patients each, to receive either 3 mL of 15 mg of 0.5 % ropivacaine with 25 mcg fentanyl [group RF] or 3 mL of 15 mg of 0.5 % bupivacaine with 25 mcg fentanyl [group BF] intrathecally. Pinprick test and Bromage scale was used to assess sensory and motor blockade, respectively. RESULTS Time taken for motor regression in group RF is lesser than that taken in group BF. CONCLUSIONS Ropivacaine along with fentanyl is more advantageous in spinal anaesthesia for infraumbilical surgeries due to brief duration of motor blockade.
