Abstract
The dosage and efficacy of spinal ropivacaine for Cesarean delivery has not been well defined. Hyperbaric ropivacaine appears to provide adequate analgesia for cesarean section. However, the use of low-dose isobaric ropivacaine for spinal anesthesia for Cesarean section has not been previously reported.
Use of ropivacaine for spinal anesthesia has been described for obstetric and non obstetric patients. Many investigators have reported ropivacaine to be less potent than bupivacaine. However, few data are available on the effect of injectant baricity on anesthesia with intrathecal ropivacaine. Previous studies with other local anesthetics have shown that the addition of glucose improved the cephalic spread and reliability of anesthesia and also shortened the duration of sensory and motor block.
