It cannot know your situation, and nothing here is a diagnosis, a dose for one person, or a decision about whether a food, medicine or procedure suits one person. Those decisions belong with a licensed clinician who can examine you.

If a reaction is happening now, use epinephrine if it has been prescribed and call 911. If you are thinking about harming yourself, call or text 988, any time.

Labor epidurals and cesarean birth: what the evidence shows

What a Cochrane review found about epidurals for labor pain, and what is known about regional and general anesthesia for cesarean birth.

2 minute read5 sources, each checked word for wordLibrary checked October 18, 2026

In short

  • Epidurals may relieve labor pain better, and satisfy more women, than non-epidural methods.E1Strong1
  • Epidurals did not change the risk of cesarean birth or long-term backache.E1Strong1
  • For cesarean birth, a review found no evidence that regional anesthesia is superior to general anesthesia for major outcomes for mother or baby.E1Strong2

Epidurals for labor

An epidural is a central nerve block: local anesthetic is injected close to the nerves that carry pain. It is widely used for pain relief in labor.E1Strong1

A Cochrane review found low-quality evidence that epidural analgesia may reduce labor pain more, and increase satisfaction with pain relief, compared with non-epidural methods.E1Strong1

Women with epidurals had more low blood pressure, leg weakness, fever and difficulty passing urine.E1Strong1

Epidurals had no effect on the risk of cesarean section or long-term backache. They did not appear to affect the baby's Apgar scores or admission to neonatal intensive care.E1Strong1

Anesthesia for cesarean birth

Regional anesthesia (spinal or epidural) and general anesthesia are both commonly used for cesarean section, and each has advantages and disadvantages.E1Strong2

A Cochrane review found no evidence that regional anesthesia is superior to general anesthesia for major outcomes for mother or baby.E1Strong2

European guidelines encourage clear fluids up to 2 hours before elective surgery, including cesarean section.E2Good3

Safety of spinal and epidural blocks

A UK national audit found serious complications of spinal and epidural blocks rare, with two thirds of initially disabling injuries resolving fully.E2Good4

For people on blood thinners, a regional anesthesia society proposes conservative times for pausing them before these blocks.E2Good5

What is not known yet

The labor review found that further research may help evaluate rare but potentially severe side effects and long-term effects on babies.E1Strong1

Questions you might bring to your anesthesia team

  1. When in labor can an epidural be placed, and is anything in my history a reason it might not be possible?
  2. What are the common side effects, and how are they managed?
  3. If I need a cesarean, what type of anesthesia is planned, and what if it is urgent?
  4. I take a blood thinner: what is the plan around the epidural or spinal?

Every claim in this guide was written from its sources and checked against them word for word. Its clinical review by Dr. Recio, a practicing nurse anesthesiologist (CRNA), is pending. This line changes when the review is done.

  1. Epidural versus non-epidural or no analgesia for pain management in labour. Anim-Somuah M, Cochrane Database Syst Rev, 2018. E1Strong Systematic review
    The words this page rests on
    Low-quality evidence shows that epidural analgesia may be more effective in reducing pain during labour and increasing maternal satisfaction with pain relief than non-epidural methods.
    Epidural analgesia had no impact on the risk of caesarean section or long-term backache, and did not appear to have an immediate effect on neonatal status as determined by Apgar scores or in admissions to neonatal intensive care.
    Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour.
    Women with epidural experienced more hypotension, motor blockade, fever, and urinary retention.
    Further research may be helpful to evaluate rare but potentially severe adverse effects of epidural analgesia and non-epidural analgesia on women in labour and long-term neonatal outcomes.
  2. Regional versus general anaesthesia for caesarean section. Afolabi BB, Cochrane Database Syst Rev, 2012. E1Strong Systematic review
    The words this page rests on
    There is no evidence from this review to show that RA is superior to GA in terms of major maternal or neonatal outcomes.
    Regional anaesthesia (RA) and general anaesthesia (GA) are commonly used for caesarean section (CS) and both have advantages and disadvantages.
  3. Perioperative fasting in adults and children: guidelines from the European Society of Anaesthesiology. Smith I, Eur J Anaesthesiol, 2011. E2Good Guideline
    The words this page rests on
    The key recommendations are that adults and children should be encouraged to drink clear fluids up to 2 h before elective surgery (including caesarean section) and all but one member of the guidelines group consider that tea or coffee with milk added (up to about one fifth of the total volume) are still clear fluids.
  4. Major complications of central neuraxial block: report on the Third National Audit Project of the Royal College of Anaesthetists. Cook TM, Br J Anaesth, 2009. E2Good Observational study
    The words this page rests on
    Serious complications of central neuraxial block (CNB) are rare.
    Two-thirds of initially disabling injuries resolved fully. The data are reassuring and suggest that CNB has a low incidence of major complications, many of which resolve within 6 months.
  5. Regional anesthesia in the patient receiving antithrombotic or thrombolytic therapy: American Society of Regional Anesthesia and Pain Medicine Evidence-Based Guidelines (fifth edition). Kopp SL, Reg Anesth Pain Med, 2025. E2Good Guideline
    The words this page rests on
    It is impossible to perform large, randomized controlled trials evaluating a complication this rare; therefore, where the evidence is limited, the authors continue to maintain an 'antihemorrhagic' approach focused on patient safety and have proposed conservative times for the interruption of therapy prior to neural blockade.
