title: [Labor induction with extra-amnial administration of PGE2 vaginal tablets].
abstract: During the period between Jan. 1 1992 and Dec. 31, 1995 at the Second Department of Gynaecology and Obstetrics in Brno labour was induced in 1159 patients by extraamnial fractionated administration of PGE2 vaginal tablets. After assessment of the indication and the baseline examination (NST, amnioscopy, US biometry and cervical score) according to the CS to the patient the first dose of PGE2 was administered into the extraamnial space beyond the inner os uteri (CS 5-8:1.0 mg PGE2, CS > 8 : 0.5 mg PGE2). After two hours the patient was examined again and if regular uterine contractions had started or the finding on the os uteri was larger than 2 cm, the amniotic sac was disrupted. If not, another dose was administered. After two hours the patient was re-examined and if the os was larger than 2 cm, and there were regular uterine contractions, the amniotic sac was disrupted. If the changes did not take place, the induction was considered a failure.
  
  
  RESULTS
  there were 1007 successful inductions (95.5%), the mean period from the onset of induction to the onset of uterine contractions was < 120 mins-269 (24.6%), 120-180 mins.: 501 (45.9%) and > 180 mins.: 322 (29.5%). The mean period of the first stage of labour was 228 mins., stage II 10 mins., stage III 8 mins. Five times uterine hypertonus was recorded and a blood loss greater than 500 ml occurred in four patients. Forty-nine Caesarean sections were made (4.2%) and 51 (4.4%) forceps deliveries. The rate of epidural analgesia was 27 (2.3%). Revision of the uterine cavity was made in 39 patients (3.4%) and manual lysis of the placenta in 30 (2.6%). The Apgar score was inferior to 6 in 10 neonates (0.9%). The protocol of induction of labour described by the authors is effective and associated with a minimum of side-effects, safe for the mother and foetus, well tolerated by patients and cost-effective.
