[PURPOSE] To evaluate the efficacy and safety of acupuncture and moxibustion treatments in breech presentation, we report correction rates and adverse events for correcting breech presentation in our department.[PARTICIPANTS AND METHODS] Subjects were pregnant women who were diagnosed with breech presentation in our obstetrics and gynecology department and started acupuncture and moxibustion treatment between April 1, 2009 and October 31, 2018. The target patients were retrospectively investigated by medical records. The main items investigated were the status of the pregnant women at the time of acupuncture and moxibustion initiation (presence or absence of threatened preterm labor), treatment position (sitting or lateral position), correction rates and occurrence of adverse events. Successful correction was defined as the rate of head position after acupuncture and moxibustion treatments. Adverse events were defined as "unfavorable medical events occurring during or after treatment, regardless of causation."[RESULTS] There were 371 pregnant women in the study; among them 57 women were diagnosed with threatened preterm labor at the start of acupuncture and moxibustion treatment, including 21 pregnant women who were in the hospital. The sitting position was used for treatment for 45.2% (168 cases) of subjects and lateral position was used for 54.7% (203 cases). The correction rates were 72.2% (268/371). In pregnant women with threatened preterm labor who were hospitalized at the time of acupuncture and moxibustion initiation, the correction rates were 28.6% (6/21 cases), which was significantly lower than that of outpatient pregnant women. There was no significant difference in the rate of correction by treatment position between sitting and lateral position. There were no adverse events of vagal reflexes when the left lateral position was treated. The frequency of adverse events per number of procedures was 1.1% (21/1916) and per number of cases was 5.7% (21/371 cases). There were two cases of rupture of membranes with no apparent causal relationship.[CONCLUSION] The safest position for treatment in pregnant women was considered to be the left lateral position. Most of the adverse events were minor or moderate, but there were two cases of rupture of membranes with no apparent causal relationship. When performing acupuncture and moxibustion for breech presentation, it is necessary to work closely with the patient's obstetrician.
