ABSTRACT: Aims: To
prevent fetal damage by excess oxytocin administration of manually controlled
infusion, by automatic and safe increasing infusion setting with monitoring
uterine contraction and fetal heart rate. Methods: Starting infusion level was 2
milliU/ml, as oxytocin sensitivity of a pregnant uterus is unknown, to avoid
hyper contraction and fetal bradycardia caused by unexpected excess oxytocin
sensitivity. The infusion automatically increased with automatic monitoring of
uterine contraction curve, then the increasing stopped when contraction reached
to normal labor level, where the infusion level maintained, which continued
until delivery, if there is no trouble. However, the infusion continued until
expiring all fluid in case of insensitive uterus, where the induction was
performed in another day. The infusion stopped automatically when contraction
was too strong, or fetal heart rate is abnormal. Thus, oxytocin sensitive case is protected from
excess contraction and fetal asphyxia. Results: Normal vaginal delivery
was achieved in 28/33 cases (85%), which was more than manually controlled infusion.
No case was abnormal in successful oxytocin infusion. Conclusion: The
automated technique will be applied to oxytocin labor induction.
