A low-dose bupivacaine: a comparison of hyperbaric and hypobaric solutions for unilateral spinal anesthesia

Abstract

As a result, unilateral spinal anesthesia with hyperbaric and hypobaric bupivacaine provided a rapid motor and sensory recovery and good hemodynamic stability, but more unilateral spinal block was achieved in patients in the hyperbaric group when compared with patients in the hypobaric group.
