Intrathecal Analgesia for Normal Labour

Status Not yet recruiting

Clinical Trial Summary

Primary outcome: Compare the duration of analgesia. Secondary outcome: analgesic potency of bupivacaine and fentanyl versus levobupivacaine and fentanyl.

Clinical Trial Description

The pain of childbirth is the most severe pain any women can endure in their life time. Painful uterine contractions lead to maternal hyperventilation and increased catecholamine concentrations resulting im maternal and fetal hypoxemia.

Labour pain when unrelieved can have adverse effect on the course of labour as well as on the fetal wellbeing. An effective labour analgesia lead to better fetal and maternal outcome.

Although the gold standard in labour analgesia is utilization of epidural services which are widely used to provide pain-free labour in many parts of the world and and have the advantage of providing flexibility to meet the needs of each patient . Epidurals have long been associated with increased oxytocin use, increased fetal malposition, increased rates of instrumental and cesarian delivery, and longer labour .

The use of single-shot intrathecal low dose found to be effective . The advantages of this form of technique include the rapidity of onset and reliability, with minimal hemodynamic changes and motor block. Spinal block is cheaper as well as less technically challenging when compared to epidural and combined spinal epidural block. Intrathecal analgesia alone is useful when duration of labour can be reasonably estimated. Opioid combined with a small dose of local anesthetic provides rapid analgesia and dissipates when no longer needed.

Bupivacaine because of its least placental transfer, due to high protein binding and minimal motor block compared to sensory block in lower doses, has become the popular choice for labor analgesia. Addition of neuraxial lipid soluble opioids permitted reduction in the dose while maintaining effective analgesia and minimizing potential adverse effects on the progress of labor and lower extremity motor block .

Levobupivacaine is the S (-) enantiomer of racemic bupivacaine. Previous studies have shown that it exhibits a clinical profile similar to bupivacaine with the added advantage of less motor impairment . ;

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.
