Primary Outcome Measures:
  • To compare the efficacy, duration of motor block until return to normal function in the non-operated leg after the start of injection, of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml when used for spinal anaesthesia in patients undergoing unilateral lower

Secondary Outcome Measures:
  • To compare the efficacy of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml in the duration of sensory block at dermatome T10 level
  • To compare the efficacy of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml in the onset time of sensory block and motor block respectively
  • To compare the efficacy of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml in the quality of anaesthesia
  • To compare the efficacy of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml in subject pain during surgery
  • To determine the safety of ropivacaine 5 mg/ml and bupivacaine 5 mg/ml by evaluating the incidence and severity of adverse events, blood pressure, pulse rate and blood loss
