Randomized Controlled Trial Comparative Study Clinical TrialComparison of the effect of two different doses of 0.75% glucose-free ropivacaine for spinal anesthesia for lower limb and lower abdominal surgery.
We compared the clinical efficacy and safety of two doses of ropivacaine for spinal anesthesia in Chinese patients undergoing lower limb and lower abdominal surgery. In this randomized, open-label study, 40 patients were divided into two groups: group A received 3.5 mL (26.25 mg) of 0.75% glucose-free ropivacaine, and group B received 4.5 mL (33.75 mg). Sensory and motor blocks were assessed during and after surgery through to complete recovery. ⋯ While shivering was more frequent in group B during the operation, the difference was not significant. Otherwise, there were no differences in adverse effects during and after surgery. We conclude that both doses of 0.75% glucose-free ropivacaine, 26.25 mg (3.5 mL) and 33.75 mg (4.5 mL), have the same efficacy and safety in Chinese patients undergoing spinal anesthesia for lower limb and lower abdominal surgery.
