Selective Spinal Anesthesia: A Comparison of Hyperbaric Bupivacaine 4 mg Versus 6 mg for Outpatient Knee Arthroscopy

Abstract

A low-dose (4 mg), low-volume (0.8 mL), low-flow (2 min) technique with hyperbaric bupivacaine toward the dependent side oriented injection and maintenance of the lateral decubitus position for 10 min produced selective spinal anesthesia with rapid recession of motor block and early discharge home.
