Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Summary

Antenatal hypnosis training, including live sessions and audio CDs, did not reduce the need for pharmacological pain relief during childbirth. This study found no significant difference in analgesia use between hypnosis groups and the control group.

Area of Science:

  • Obstetrics and Gynecology
  • Complementary and Alternative Medicine
  • Pain Management

Background:

  • Childbirth pain management often involves pharmacological interventions.
  • Antenatal education aims to prepare women for labor and explore non-pharmacological pain relief options.
  • Hypnosis has been explored as a complementary approach to manage labor pain.

Purpose of the Study:

  • To evaluate the effectiveness of antenatal hypnosis in reducing the use of pharmacological analgesia during childbirth.
  • To compare the outcomes of live antenatal hypnosis sessions with audio CD-based hypnosis and standard care.

Main Methods:

  • A randomized controlled trial involving 448 pregnant women planning a vaginal birth.
  • Participants were assigned to either standard care, audio CDs only, or live hypnosis sessions plus audio CDs.
  • The primary outcome measured was the use of pharmacological analgesia during labor and childbirth.

Main Results:

  • No statistically significant difference was observed in the use of pharmacological analgesia between the hypnosis groups (Hypnosis + CD, CD only) and the control group.
  • The relative risk for pharmacological analgesia use was 1.07 (95% CI 0.95-1.20) for Hypnosis + CD versus control, and 1.01 (95% CI 0.89-1.15) for CD only versus control.

Conclusions:

  • Antenatal group hypnosis, as delivered through the Hypnosis Antenatal Training for Childbirth (HATCh) intervention, does not appear to reduce the need for pharmacological pain relief during labor.
  • Further research may be needed to explore different hypnosis protocols or patient populations.
