Comparison of the Effectiveness and Safety of Segmental Thoracic Spinal Anesthesia Using Isobaric Levobupivacaine 0.5% Versus Hyperbaric Levobupivacaine 0.5% in Performing Laparoscopic Cholecystectomy: A Prospective Randomized Controlled Trial

Hyperbaric levobupivacaine provided faster block onset and offset, improved satisfaction, better hemodynamic stability, and quicker recovery. It is a safe and effective anesthetic choice for laparoscopic cholecystectomy, offering predictable block spread and fewer adverse effects compared to isobaric levobupivacaine.
