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