Abstract
To evaluate the effect of dexamethasone administration on the interval between initiation of labor induction and active phase of labor.
Background
Induction of labor refers to the process of stimulating contractions before the spontaneous onset of labor, either with or without ruptured membrane. Labor induction can be considered as a therapeutic intervention when the benefits of precipitous delivery to either the mother or the fetus are greater than the risks of pregnancy continuation [ 1 ].
Methods
Systematic Reviews and Meta-Analyses of Randomized Controlled Trials (RCTs) were used to conduct this systematic review [ 17 ].
Results
Figure 1 Shows the flowchart of the selection process of studies. In our search of databases, 2672 articles were obtained as follows: Cochrane Library ( n = 80), Scopus ( n = 493), Web of Science ( n = 178), PubMed ( n = 1119), and EMBASE ( n = 802).
Discussion
This systematic review aimed to evaluate the effect of dexamethasone on labor induction.
Conclusion
Dexamethasone could significantly reduce the length of the time interval between induction and active phase and length of the first stage of labor with no difference in maternal or fetal adverse effects.
