Retrospective Analysis of the Factors Affecting the Induction of Childbirth in 4350 Women from a Single Center in Warsaw, Poland

Factors Influencing Induction of Labor Success in Riyadh, Saudi Arabia

Introduction

The physiological process by which the fetus and placenta are delivered from the uterus and pass through the vaginal canal for delivery is known as labor. Induction of labor involves deliberately initiating labor before it occurs naturally, using medical interventions or techniques to stimulate contractions and initiate the birthing process.

Aim

This study aimed to investigate the factors that influence the success of labor induction procedures in Riyadh, Saudi Arabia, from January to April 2023. Subject and Methods. This retrospective chart review was conducted at the National Guard Hospital in Riyadh, Saudi Arabia. Data were collected from the patient chart of those who underwent labor induction from January to April 2023. The collected data were tabulated and cleaned in MS Excel. Final data were transferred to SPSS for subsequent data analysis.

Results

Five hundred and thirty-one pregnant women were analyzed. 52.7% were aged 30 years or below. The most common indication of IOL was post-dated pregnancy (26.2%). 62% were normal deliveries, indicative of IOL success, while 31.1% were cesarean deliveries, indicative of IOL failure. In univariate analysis, women with lower gravidity (≤3) and who had received Propess were associated with cesarean delivery. In a multivariate regression analysis, women who received Prostin and increased parity were identified as the significant independent predictors of IOL success.

Conclusion

IOL's success was dependent primarily on increasing parity and Prostin administration. However, lower gravidity (≤3) and Propess medication could lead to operative procedures among pregnant women. Hence, it is necessary to carefully assess the condition of pregnant women before directing them to IOL.

Assessment of different sonographic cervical measures to predict labor induction outcomes: a systematic review and meta-analysis

Background

Induction of labor (IOL) is a common obstetric approach to start or encourage uterine contractions to achieve a vaginal birth. It is recommended when continuing the pregnancy may be more dangerous for the mother or baby. Different ultrasonographic measures, such as cervical length, have been investigated as possible predictors of the outcomes of IOL. This meta-analysis aimed to assess the accuracy of ultrasound measurements in anticipating successful IOL.

Methods

The study conducted a thorough search on three databases (PubMed, Scopus, and Web of Science) until 04 March 2023, to find clinical studies published in English that reported different sonographic cervical measures and their ability to predict IOL outcomes. The chosen studies were stratified based on the type of indicator reported, and a meta-analysis was conducted to determine the best indicator for both successful and failed induction. The risk of bias and concerns about the applicability of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) method.

Results

This study analyzed 57 studies with 9,338 patients. Cervical length is moderately effective in predicting successful IOL, with pooled sensitivity (SN) and specificity (SP) of 0.67 and 0.70, respectively. However, cervical length had a pooled SN and SP of 0.70 and 0.61 for predicting failed IOL. The posterior cervical angle was found to have a higher pooled SN and SP of 0.79 and 0.73 for predicting successful IOL. Fetal head-perineum distance demonstrated moderate accuracy with a pooled SN, SP, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the curve of 0.58, 0.66, 1.95, 0.36, 5.33, and 0.9992, respectively, for predicting successful IOL.

Conclusions

Fetal head-perineum distance was the most effective predictor for successful IOL compared to cervical length, which only had a moderate predictive ability. Shortening of cervical length was not a useful indicator for successful IOL. On the other hand, the posterior cervical angle was the most reliable factor for predicting failed induction. The study's findings can aid in developing more effective management strategies for IOL.
