Decreased Neuraxial Morphine After Cesarean Delivery

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to compare 50mcg to 150mcg morphine in epidural for the goal of decreasing side effects of medication with lower dose in patients who receive a QL block

Clinical Trial Description

Regional anesthesia has been associated with reduced opioid consumption after surgery. Cesarean delivery is one of the most commonly performed surgeries worldwide and women undergoing cesarean delivery are often young, opioid-naïve, and motivated to recover quickly in an effort to better care for their newborn. However, approximately 1 in 300 opioid naïve women become persistent prescription opioid users following cesarean delivery . Hence, it is important to optimize post-cesarean pain control while limiting exposure to opioids. Currently, standard therapy includes the use of neuraxial morphine (NM) in combination with a multi-modal regime in an effort to limit excessive opioid use after cesarean delivery. The current typical dose of NM that is given prior to cesarean delivery at the investigator's center is 150 mcg. Importantly, NM doses as low as 100 mcg have been shown to provide comparable analgesia while reducing side effects such as itching. The side-effect profile associated with NM includes up to 87% of patients experiencing pruritus and up to 70% experiencing urinary retention. Nausea and vomiting also lead to significant discomfort for a new mother trying to provide acute infant care. Adjunctive Peripheral Nerve Blockade has recently been introduced to reduce postoperative pain and opioid use. Studies have assessed the usefulness of the transversus abdmoninis plane (TAP) block after cesarean delivery. Another ultrasound-guided injection of local anesthetic in the fascial plane (truncal block) that is available at UAB and within the standard of care for patients undergoing abdominal surgery is the quadratus lumborum (QL) block. Because of its more posterior and caudal location, it is more likely to anesthetize the nerve fibers associated with pain from cesarean delivery. This study will compare the use of 50mcg to 150mcg morphine for the goal of decreasing side effects of medication with lower dose in all patients who receive a QL block ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
