Labour Epidurals — What the Evidence Says About Safety and Outcomes

For many women, an epidural offers the most effective pain relief during labour. But questions often arise: Does it increase the chance of a caesarean? Is it safe for the baby?
Research over the last two decades provides clear, reassuring answers.

Do Epidurals Increase Caesarean Rates?
A common concern is whether having an epidural makes a caesarean delivery more likely.

  • A Cochrane Review of over 40 trials (including more than 11,000 women) showed no increase in caesarean birth rates for women who chose epidurals.
  • There may be a slight increase in assisted vaginal births (forceps or vacuum), though this risk has reduced with modern, low-dose epidural techniques.

Maternal Safety
Large studies have found that epidurals can actually improve safety for mothers.

  • A 2023 study of over 570,000 women found epidurals were linked to a 35% reduction in severe maternal complications, including very high blood pressure and bleeding.
  • Side effects can include temporary low blood pressure, fever, or difficulty passing urine. Rarely, headaches occur after the procedure. Permanent nerve injury is extremely rare (about 2 in 100,000 cases).

Effects on the Baby

  • A Scottish study of over 435,000 births found no increased risk of poor outcomes for babies of mothers who had epidurals.
  • This includes measures like Apgar scores, NICU admissions, and long-term development.

Key Takeaway
Epidurals are a safe and effective option for pain relief in labour. They do not increase the chance of a caesarean birth and may even improve maternal safety. Your anaesthetist and midwife will discuss your options and support you in making the best choice for your labour and delivery.

Accidental Awareness During General Anaesthesia — How Rare Is It?

Accidental awareness during general anaesthesia is very uncommon. Modern monitoring and strict safety protocols make it an even rarer event. If you are worried, your anaesthetist will be happy to discuss the steps taken to keep you safe and comfortable...

Why Your Medications Matter Before Surgery

Hi, my name is Jules. I’ve been a pharmacist for over 10 years, working in both hospital settings and anaesthesia pre-assessment clinics.

Your anaesthetist will give you clear instructions about which medications to take, and which to stop, in the lead-up to your procedure. Following these carefully helps ensure the best outcome during your operation and your recovery afterwards.

What is Pain, and Why Does it Feel Different for Everyone?

When most of us think about pain, we picture it as a simple alarm system: something gets injured, nerves send a signal, and we feel pain. But modern science tells us it’s not that straightforward.
The International Association for the Study of Pain (IASP) defines pain as: “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage.” In other words — pain is not just about your...

Smoking vs Vaping Before Surgery: What’s Worse – And How to Reduce Risks

When preparing for surgery, one of the most important things you can do to improve your recovery is to stop smoking or vaping. Many patients ask us: “Which is worse before surgery — smoking or vaping?” The truth is, both carry risks, though in slightly different ways.
The good news is, stopping even for a short time makes a real difference. ANZCA and international guidelines recommend: Stop as soon as possible — ideally 4–8 weeks before surgery, but even 24–48 hours can improve oxygen delivery and heart function....
