Noninvasive controlled abortion in the trimester of pregnancy ( a 15- years experience )

A study on the development of an efficient method for late induced abortion that prioritizes safety and minimizes complications. The stages of noninvasive controlled abortion are discussed, including cervical maturation and uterine contractions. Various means of cervical maturation and uterine contractions are explored, along with their effects on hormone levels and duration of abortion.

  1. Noninvasive controlled abortionin the trimester of pregnancy (a 15-years experience) N.V.Оrdzhonikidze, B.L..Gurtovoi, N.М.Каsаboulatov Research centre of Obstetrics, Gynecology & Perinatology Russian Academy of Medical Sciences High Risk Pregnancy Dept

  2. Main trends • Search for reasonable conservatism • Maximum safety • Limited operative intervention

  3. Objectives Elaboration of efficient method of late induced abortion with the purpose to enhance its safety and reduce complication rate.

  4. Stages of noninvasive controlled abortion in the II trimester • Maturation of the uterine cervix • Activation of contractions

  5. Neans of cervical maturation • Prostaglandins (cerviprost, prepidil-gel),intracervical,n=106 • Laminaria, intracervical, (dilapan) n=114 • Step by step combination of gel and laminaria (dilapan), n=80

  6. Means of uterine contractions • nalador-500 (sulproston-derivative of prostaglandin E2(«Schering», Germany), n=250 • prostin 15/М – derivative of prostaglandin F2-α («Updjohn»,USA), n=50
