Induction of Labor;

Abstract

Efficacy and safety of intra-vaginal prostaglandin E2 pessary for induction ofLabor. Objectives: To evaluate the efficacy and safety of intra-vaginal prostaglandin E2 pessaryfor induction of Labor. Study Design: Case control study. Setting: Gynecological and obstetricward of Liaquat University of Medical and Health Sciences Hospital, Hyderabad. Period: 14 Feb2012 to 13 Feb 2013. Study Population: All the Pregnant women at term or post term admittedin gynae ward from 14th February 2012 to 13th February 2013. Results: 100 women recruitedin the study, study carried out at Gynecological ward of Liaquat University of Medical and HealthSciences Hospital Hyderabad. Analysis of booking status listed in Table-I revealed that 68% (n= 68) were un-booked having no antenatal care and 32.0% (n = 32) were booked. There wereno protocol violation, relation to the parity listed in Table-II showed maximum number of patients(n = 62) 62.0% Primigravida and (n = 38) 38.0% multigravidas were include. Age distributionis listed in Table-III maximum patients (n = 49) 49.0% at age between 26 - 35 years, 35 (35.0%)were between 20 - 25 years, 10 (10.0%) were >35 years and 06 (6.0%) patients were belong toless than 20 years. Regarding the gestational age 57 (57.0%) patients in our study presentedbetween 37 - 39 weeks of gestation. However, 47 (47.0%) patients were at 40 - >40 weeksof gestation showed in the (Table-IV). Indication for cervical ripening and induction of laboris listed on Table-V commonest indication was pregnancy induced hypertension followed byprolonged pregnancy, and IUGR etc. Table-VI shows the Bishop score 30 (30.0%) had BishopScore 2 – 3, while 70(70.00%) had a bishop score 4-5. Table-VII shows induction-deliveryinterval, Greater number of women (66/100) delivered within 24 hours of start of induction.Table-VIII showed mode of delivery, majority of the women had normal vaginal deliveries 64.00while 16 deliveries by assisted vaginal deliveries while in remaining 20 cases caesarean sectiondone. Table-IX shows four babies had an Apgar score 4/10 at end of 1 min and 7/10 at end of5 min, whereas 96 babies had an Apgar score of 9/10 in 1 min. The indications for caesareansection are shown in Table-X. There were 09(9%) cases of failed induction, 11 cases of a fetaldistress (Meconium stained liquor). There was no increased incidence of neonatal sepsis orChorioamniotis or puerperal sepsis in any of our patients. No perinatal morbidity or mortalityor any severe maternal complications were noted while mild side effects were noted which ismentioned in (Table-XI). Conclusion: In developed countries prostaglandin E2 are widely usedfor ripening of unfavorable cervix in induction of labor but patient response vomiting, diarrhea,tachycardia, and fever are commonly observed minor side effects. Induction with Prostaglandinreduced the rate of pregnancies progressing beyond 41 weeks and related feto-maternalmorbidity and mortality. After excluding contra indication all women should be offered inductionat 41 completed weeks. Induction with prostaglandin with medical disorder like preeclampsia issafe and better feto maternal outcome.
