Hypnosis Antenatal Training for Childbirth: a randomised controlled trial

Objective To determine the use of pharmacologic analgesia during childbirth when antenatal hypnosis is added to standard care. Design Randomised controlled clinical trial, conducted from December 2005 to December 2010. Setting The largest tertiary referral centre for maternity care in South Australia. Population A cohort of 448 women at > 34 weeks of gestation, with a singleton pregnancy and cephalic presentation, planning a vaginal birth. Exclusions were: the need for an interpreter; preexisting pain; psychiatric illness; younger than 18 years; and previous experience of hypnosis for childbirth. Methods All participants received usual care. The group of women termed Hypnosis + CD (hypnotherapist guided) were offered three antenatal live hypnosis sessions plus each session's corresponding audio CD for further practise, as well as a final fourth CD to listen to during labour. The group of women termed CD only (nurse administered) were played the same antenatal hypnosis CDs as group 1, but did not receive live hypnosis training. The control group participants were given no additional intervention or CDs. Main outcome measure Use of pharmacological analgesia during labour and childbirth. Results No difference in the use of pharmacological analgesia during labour and childbirth was found comparing hypnosis + CD with control (81.2 versus 76.2%; relative risk, RR 1.07; 95% confidence interval, 95% CI 0.95-1.20), or comparing CD only with control (76.9 versus 76.2%, RR 1.01, 95% CI 0.891.15). Conclusions Antenatal group hypnosis using the Hypnosis Antenatal Training for Childbirth (HATCh) intervention in late pregnancy does not reduce the use of pharmacological analgesia during labour and childbirth.
