Comparison of Different Bupivacaine and Fentanyl Combinations When Used with A Single Shut Spinal Block for Labor Analgesia

Abstract

Background: Single-shot spinal analgesia with bupivacaine plus a short-acting opioid is an effective technique for pain control in labor, and it is particularly useful in the active phase. We compared the effects of adding two different doses of fentanyl (15 μg or 25 μg) to intrathecal bupivacaine, and to evaluate the impacts on duration of labor analgesia, newborn, and side effects.
