Hyperbaric ropivacaine and bupivacaine

Evaluation of Hyperbaric Spinal Ropivacaine in Lower Limb and Hip Surgery: A Comparison with Hyperbaric Bupivacaine

Objectives: In this clinical study hyperbaric ropivacaine in spinal anaesthesia for lower limb and hip surgery was evaluated and results obtained were compared with those using hyperbaric bupivacaine. Methodology: Two hundred patients scheduled for lower limb and hip surgery were randomly divided into two groups of 100 patients each. These patients received a spinal injection of either 3ml (15m...

Minimum effective local anesthetic dose of intrathecal hyperbaric ropivacaine and bupivacaine for cesarean section.

BACKGROUND Intrathecal anesthesia is commonly used for cesarean section. Bupivacaine and ropivacaine have all been used as intrathecal drugs. The minimum effective local anesthetic dose (MLAD) of intrathecal ropivacaine for non-obstetric patients has been reported. However, few data are available on the MLAD of hyperbaric ropivacaine for obstetric patients and the relative potency to bupivacain...

Intrathecal anesthesia: ropivacaine versus bupivacaine.

We compared intrathecal ropivacaine to bupivacaine in patients scheduled for transurethral resection of bladder or prostate. Doses of ropivacaine and bupivacaine were chosen according to a 3:2 ratio found to be equipotent in orthopedic surgery. One hundred patients were randomly assigned to blindly receive either 10 mg of isobaric bupivacaine (0.2%, n = 50) or 15 mg of isobaric ropivacaine (0.3...

Ropivacaine and bupivacaine in obstetric analgesia.

Studies comparing the efficacy of epidural analgesia for labour have been limited by lack of knowledge about the relative potencies of the involved agents, whether alone or in combination. Recently a clinical model to determine the minimum local analgesic concentration has been developed [1]. This study design estimated the minimum local analgesic concentration or median effective concentration...
