Randomized Controlled Trial Comparative Study Clinical TrialA double-blind comparison of the abdominal wall relaxation produced by epidural 0.75% ropivacaine and 0.75% bupivacaine in gynecologic surgery.
Ropivacaine is a long-acting local anesthetic agent with similar potency to that of bupivacaine when administered for epidural anesthesia. Ropivacaine, however, may be less cardiotoxic than bupivacaine. Epidural bupivacaine and ropivacaine have been shown to be equally effective in providing sensory block for lower extremity surgery, but they have not been compared for their ability to produce abdominal wall relaxation. ⋯ Both 0.75% ropivacaine and 0.75% bupivacaine provide adequate surgical anesthesia for lower abdominal surgery when administered epidurally. However, lower extremity motor block with ropivacaine is significantly shorter and of slower onset and sensory block shorter at these concentrations.

Randomized Controlled Trial Comparative Study Clinical TrialInfluence of baricity on the outcome of spinal anesthesia with bupivacaine for lumbar spine surgery.
Although the majority of elective lumbar spine surgical procedures are performed under general anesthesia, successful use of spinal and epidural anesthesia has been reported. This study was designed to evaluate the influence of baricity on the performance of spinal anesthesia for lumbar spine surgery. ⋯ Plain bupivacaine is superior to hyperbaric bupivacaine for spinal anesthesia for elective lumbar spine surgery.
