[Unilateral spinal anesthesia with low 0.5% hyperbaric bupivacaine dose.].
BACKGROUND AND OBJECTIVES Unilateral spinal anesthesia may be advantageous, especially for outpatient procedures. Low anesthetic doses, pencil point or cutting point needles, slow injection rate and the lateral position have been reported as helping unilateral spinal anesthesia technique. This longitudinal study aimed at investigating the depth of unilateral spinal anesthesia with 5 mg of 0.5% ...
متن کاملIntrathecal 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...
