Volume 56, Issue 6 (7-1998)
Abstract
The present research is a quasi-experimental prospective study to determine usefulness of stripping the fetal memberanes at term for preventing of postterm pregnancy. 212 pregnant women with firm gestational dates entered the study, 112 underwent stripping of the membranes and 100 controls did not. The difference between the number of patients who advanced beyond term (>290 days) was statistically significant between groups (P<0.01). The mode of delivery and neonatal APGAR score were similar in both groups.
Management and outcome of prolonged pregnancies in Shariati university hospital

Volume 65, Issue 12 (3-2008)
Abstract

Background: There is dearth of reports from Iran regarding the prevalence of postterm pregnancy and its complications. The present study was conducted to evaluate the prevalence, management and outcome of prolonged pregnancies.

Methods: This cross-sectional study included data from the hospital records of all women referred to Shariati Hospital, Tehran, from 2001 to 2002 with pregnancies of more than 40 weeks in duration. Pregnancies ≥40-42 weeks were considered postdate and those more than 42 weeks postterm pregnancy. The data compiled from the hospital records were subjected to t, χ2 and Mann-Whitney U tests.

Results: Of the 1500 deliveries in this hospital, 98 patients were included in this study, 66.3% of whom were nullipara and 33.7% multipara. The prevalence of postterm pregnancy was estimated to be 3.3%. Cervix dilation of 2 cm or less on admission occurred in 65 women (73.3%). The mean Bishop score was 4.31. Of the 62 fetuses that underwent assessment tests, 54 (87.1%) were normal. The median time between the last test and induction of labor was 2.1 days, and 2.6 days for cesarean deliveries, which was not a significant difference (P=0.6). Cervical ripening with misoprostrol was performed in 36 cases (36.7%) and was successful in 18 cases. In this group, the median time for cervical ripening in multiparas was significantly less than nulliparas (4 vs. 7 hrs, P=0.004). Women not subjected to cervical ripening had a higher cesarean rate than those who did undergo cervical ripening (74.7% vs. 66.1%), although this difference was not significant (P=0.9). Vaginal and cesarean delivery rates showed no significant difference between cases that underwent induction with oxytocin and those subjected to cervical ripening with misoprostol (P=0.9). The mean Apgar score was 9.5, with all scores above 6. There were no cases of neonatal hypoglycemia, hypocalcemia, NICU admission or prenatal death. The mean nursery stay was 1.84 days with a range of 1-8 days.

Conclusions: The prevalence of postterm pregnancies was 3.3% in this study, due in part to erroneous estimation of gestational age. Sonography exam in the first half of pregnancy can provide a better estimation of gestational age and thereby reduce the rate of postterm pregnancy. Cervical ripening and induction of labor shorten the duration of pregnancy however, whether it has any beneficial effect on neonatal outcome remains controversial.


Induction of labor in term pregnancy: Sublingual versus vaginal misoprostol
Beigi A, Kazemipour Sm, Tabarestani H,
Volume 68, Issue 3 (6-2010)
Abstract
Background: Induction of labor implies stimulation of contractions before the spontaneous onset of labor and is indicated when have benefits to eighter mother or fetus. Uterine contractions and an appropriate cervix are two important factors in labor and are contributed to good outcomes. Nowadays, there are many therapeutic modalities for it such as misoprostol. Both vaginal and oral misoprostol may be used for eighter cervical ripening or labor induction. The tablets are stable at room temperature. Regarding the issue importance and lack of similar studies in Iran, this study was conducted to compare the efficacy of sublingual and vaginal misoprostol for labor induction. Methods: This study was conducted as a randomized double-blind clinical trial. In this survey, 250 women were randomly assigned to receive 25 g vaginal misoprostol plus sublingual placebo or 25 g sublingual misoprostol plus vaginal placebo in Arash hospital Tehran, Iran from 2008 to 2010. The maternal and fetal complications, Bishop Score, and time of pain onset and it’s interval with labor were monitored in two groups analyzed. Results: Mean Bishop Score, and time of pain onset and its interval with labor were similar in two groups (p>0.05). 43 patients (34.4%) in sublingual and 54 (43.2%) in vaginal group had normal vaginal delivery (p>0.05). The frequencies of maternal and fetal complications were similar between two groups (p>0.05). Conclusion: It may be concluded that there is no difference between efficacy of sublingual and vaginal misoprostol in pregnancy outcomes, maternal and fetal complications and so each one may be used according to pregnant woman’s condition and physician attitude.

Volume 80, Issue 8 (11-2022)
Abstract
Background: The aim of this study was to find the causes of failure of natural childbirth in late-term pregnancy that can be useful for managing childbirth in these pregnant mothers and to design a solution to increase natural childbirth.
Methods: This cross-sectional study was conducted in the community of pregnant women with a late-term pregnancy of more than 41 weeks. The studied sample includes 148 pregnant mothers who were referred to Ayatollah Rouhani Hospital in Babol from March 2018 to February 2020. Mother's age, Body Mass Index, gestational age, number of pregnancies, number of deliveries, length of hospitalization, the state of the cervix and preparation method of the cervix for termination of pregnancy were extracted and recorded from patients' files. Data were compared in two groups of pregnancy termination methods (natural childbirth and cesarean delivery). Statistical analysis was done using SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) and Chi-square test and Student’s t-test statistical tests and logistic regression model fitting. P-value less than 0.05 was considered significant.
Results: In this study, 167 pregnant women with late-term pregnancy were studied. The age of pregnant women is reported with mean of 26.03 and standard deviation 5.98 of years. The high Bishop variable, with odds ratio of 0.44, is a variable protective factor for cesarean delivery (P=0.001). Higher body mass index with odds ratio of 1.09, is also known as a risk factor for cesarean delivery (P=0.01), so that for each unit of increase in Bishop score, the chance of cesarean delivery decreases by 56% and for each unit of increase in body mass index, the chance of cesarean delivery increases by 9%.
Conclusion: This study showed that nearly half of cases of late pregnancies lead to normal delivery. High body mass index reduces the chance of normal delivery in late term pregnancies. But a higher Bishop score can be effective in the success of natural delivery.
