To assess the effectiveness of hypnosis to reduce pain and facilitate external cephalic version (ECV).
Cohort study.
Geneva University Hospitals, Switzerland.
63 women attempting ECV under hypnosis from 2010 to 2011 were compared with 122 women who received standard care from 2005 through 2008.
Immediately after the ECV attempt, both groups completed the same questionnaire evaluating the participants' pain (visual analogue and verbal rating scales) and experience with the procedure. Physicians also completed a questionnaire that elicited their views on the effect of hypnosis on the intervention. A chi-squared test was used to compare differences in proportions, and the Mann-Whitney U test was used for differences in continuous variables. A thematic content analysis of the obstetricians' responses to the open question regarding their experience of hypnotist accompaniment was also performed.
Pain evaluated by women (visual analogue and verbal rating scales) and success rate of ECV.
Pain intensity reported by women did not significantly differ between the hypnosis group and the standard care group (visual analogue scale score, 6.0 versus 6.3, respectively; p=.25; difference for verbal rating scale, p=0.31. In 72% of cases, physicians reported that hypnosis facilitated the procedure. The success rates in both groups were not significantly different (30% with hypnosis compared with 38% without; p=.31). Most women in both groups found the ECV attempt painful and a source of anxiety but would undergo it again if necessary.
Hypnosis accompaniment during ECV does not reduce pain intensity associated with the procedure or improve the probability of a successful version.
评估催眠在减轻疼痛和促进外倒转术（ECV）中的效果。
队列研究。
瑞士日内瓦大学附属医院。
2010 年至 2011 年间，63 名尝试在催眠下进行 ECV 的女性与 2005 年至 2008 年期间接受标准护理的 122 名女性进行比较。
在 ECV 尝试后，两组参与者均填写相同的问卷，评估参与者的疼痛（视觉模拟评分和口头评分）和对程序的体验。医生也填写了一份问卷，了解他们对催眠对干预效果的看法。使用卡方检验比较比例差异，使用 Mann-Whitney U 检验比较连续变量差异。还对妇产科医生对关于催眠陪伴经验的开放性问题的回答进行了主题内容分析。
女性评估的疼痛（视觉模拟评分和口头评分）和 ECV 的成功率。
女性报告的疼痛强度在催眠组和标准护理组之间没有显著差异（视觉模拟评分分别为 6.0 和 6.3，p=0.25；口头评分差异，p=0.31）。72%的医生报告说催眠有助于该程序。两组的成功率没有显著差异（催眠组 30%，无催眠组 38%；p=0.31）。两组中的大多数女性都发现 ECV 尝试很痛苦，是焦虑的来源，但如果需要，会再次进行。
ECV 期间的催眠陪伴并不能减轻与该程序相关的疼痛强度，也不能提高成功版本的概率。
