ABSTRACT

Objective To discuss the nursing care for patients with placenta previa,who receive uterine arterial catheterization and embolization in the second trimester of pregnancy. Methods By using superselective catheterization with Seldinger technique,bilateral uterine artery angiography and embolization were performed in 16 patients with placenta previa in the second trimester of pregnancy. Two to four hours after the procedure,rivanol intra-amniotic injection was employed to induce the abortion. Close perioperative observation and careful nursing were carried out. Results The fetus with its subsidiary tissue was delivered in a mean time of 4.5 hours after the operation in 15 cases. No postpartum hemorrhage occurred. Induced abortion failed in one case with 26 weeks pregnancy because of a scar uterus and cervical dystocia. Hysterotomy was performed 6 days later,blood loss during the operation was about 100 ml. No nursing care related complications occurred in all 16 patients. Conclusion Uterine arterial embolization is very helpful in making the induced abortion for the treatment of bleeding placenta previa in the second trimester of pregnancy. Strengthening of perioperative care can improve successful rate of interventional therapy and prevent the occurrence of complication.
