RESUMEN
OBJECTIVES: To evaluate the efficacy of moxibustion for the correction of fetal breech presentation in a non-Chinese population. DESIGN: Single-blind randomised controlled trial (RCT). SETTING: Six obstetric departments in Italy. SAMPLE: Healthy non-Chinese nulliparous pregnant women at 32-33 weeks + 3 days of gestational age with the fetus in breech presentation. METHODS: Random assignment to treatment or observation. Treatment consisted of moxibustion (stimulation with heat from a stick of Artemisia vulgaris) at the BL 67 acupuncture point (Zhiyin) for one or two weeks. Two weeks after recruitment, each participant was subjected to an ultrasonic examination of the fetal presentation. MAIN OUTCOME MEASURE: Number of participants with cephalic presentation in the 35th week. RESULTS: The study was interrupted when 123 participants had been recruited (46% of the planned sample). Intermediate data monitoring revealed a high number of treatment interruptions. At this point no difference was found in cephalic presentation in the 35th week (treatment group: 22/65, 34%; control group: 21/58, 36%; RR 0.95; 99% CI 0.59-1.5). CONCLUSIONS: The results underline the methodological problems evaluating of a traditional treatment transferred from a different cultural context. They do not support either the effectiveness or the ineffectiveness of moxibustion in correcting fetal breech presentation.
