Continuous infusion and intermittent injection of epidural bupivacaine offer effective labor analgesia. Both methods provide similar pain relief and do not prolong labor, with intermittent injections showing fewer side effects like hypotension.

Area of Science:

  • Anesthesiology
  • Obstetrics
  • Pharmacology

Background:

  • Labor analgesia is crucial for maternal comfort during childbirth.
  • Epidural anesthesia is a common method for pain management during labor.
  • Different administration techniques for epidural analgesia exist, each with potential benefits and drawbacks.

Purpose of the Study:

  • To compare the efficacy and safety of continuous infusion versus intermittent injection of epidural bupivacaine for labor analgesia.
  • To evaluate pain scores, mode of delivery, and maternal complications in two epidural bupivacaine administration groups.

Main Methods:

  • A randomized controlled trial involving 20 healthy parturients receiving epidural bupivacaine with pethidine.
  • Participants were assigned to either continuous infusion (10 ml/hour) or intermittent injection (10 ml hourly) of 0.1% bupivacaine.

  • Analgesic efficacy, patient satisfaction, motor block, and complications were assessed and compared between groups using statistical tests.
  • Main Results:

    • Both continuous infusion and intermittent injection provided excellent or comfortable labor analgesia.
    • No statistically significant differences were observed in pain scores or labor duration between the groups.
    • The intermittent injection group had fewer instances of hypotension and motor block compared to the continuous infusion group.

    Conclusions:

    • Continuous infusion and intermittent injection of low-dose bupivacaine are effective for labor pain relief in the study's context.
    • Both methods demonstrate similar analgesic efficacy and do not prolong the second stage of labor.
    • Intermittent injection may be associated with a lower incidence of adverse effects such as hypotension and motor block.
