Intrathecal fentanyl with hyperbaric levobupivacaine 0.5% in fractionated versus sequential dose spinal anaesthesia: Randomized controlled trial

Spinal anesthesia has significantly evolved, offering various techniques and adjuvants to enhance efficacy and patient outcomes. Notably, the combination of intrathecal fentanyl with hyperbaric levobupivacaine is of great interest. This study compares the efficacy of this combination when administered through Sequential Spinal Anesthesia (SSA) and Fractionated Spinal Anesthesia (FSA).

Hyperbaric levobupivacaine, a long-acting local anesthetic with reduced cardiovascular toxicity, is favored in spinal anesthesia. When combined with fentanyl, known for its rapid onset and analgesic properties, it potentially enhances spinal anesthesia quality by providing optimal intraoperative conditions and extended postoperative analgesia.

FSA, an innovative technique to mitigate hypotension, administers the local anesthetic in fractions with short intervals, aiming for a more controlled block with fewer hemodynamic issues. However, concerns about complications like post-dural puncture headache and neurological deficits limit its use.

In contrast, SSA involves sequential administration of anesthesia components, each tailored to exploit specific benefits, offering an alternative to FSA’s challenges. The baricity of the fentanyl and hyperbaric levobupivacaine mixture can affect local anesthetic spread in cerebrospinal fluid (CSF), impacting anesthesia efficacy.

Research indicates that mixing adjuvants with hyperbaric bupivacaine can alter CSF distribution, whereas administering them separately might avoid these changes, improving onset, duration, and hemodynamic stability.

The study evaluates FSA versus SSA by examining sensory and motor blockade onset and duration, intraoperative conditions, and hemodynamic stability. This research aims to fill gaps in existing literature and enhance spinal anesthesia practices, aiding practitioners in providing better patient care.

This study seeks to critically examine and compare the efficacy of intrathecal fentanyl with hyperbaric levobupivacaine 0.5% when administered through two different dosing strategies fractionated spinal anaesthesia and sequential spinal anaesthesia. Key parameters under scrutiny include the onset and duration of sensory and motor blockade, intraoperative conditions, and hemodynamic stability. This research endeavours to contribute nuanced insights into refining spinal anesthesia administration techniques, ultimately aiming for enhanced patient safety, comfort, and positive perioperative experiences.

By shedding light on the comparative merits of Sequential and Fractionated Spinal Anesthesia, this investigation aspires to guide anaesthetic practitioners in making informed decisions, advancing the standards of spinal anesthesia practice for improved patient care.
