Background: Protracted labor is associated with an elevated risk of maternal and fetal complications. Results of randomized controlled trials on the efficacy in labor of phloroglucinol (PHL), a pure antispasmodic drug, are uncertain. Objectives: To evaluate whether PHL is effective in shortening the first stage of labor. Search strategy: MEDLINE, EMBASE, LILACS, Scopus, ClinicalTrials.gov, and the Cochrane Library were searched from inception to July 2020. Selection criteria: Randomized controlled trials (RCTs) concerning women with a singleton vertex pregnancy at term who were treated with PHL. Data collection and analysis: Relevant data were extracted and tabulated. Review Manager 5.3 was used for data analysis. Primary outcome evaluated was the mean reduction of the first stage of labor. Main results: Five RCTs, including 487 pregnant women, were analyzed. The first stage of labor duration was significantly shorter in the treatment arm compared to the control group [MD−113.21 min (95% CI−119.63,–106.79)]. A significant shortening of the second stage was achieved in the PHL group [MD−11.12 min (95% CI−12.64,–9.75)] while no differences were reported for the third stage. Conclusions: PHL might represent an effective treatment to shorten the duration of the first and second stage of labor. Synopsis: A meta‐analysis of 5 trials found that Phloroglucinol favorably impacts on the total duration of the labor in primiparae and multiparae women with a singleton pregnancy.

Abstract

Background: Protracted labor is associated with an elevated risk of maternal and fetal complications. Results of randomized controlled trials on the efficacy in labor of phloroglucinol (PHL), a pure antispasmodic drug, are uncertain. Objectives: To evaluate whether PHL is effective in shortening the first stage of labor. Search strategy: MEDLINE, EMBASE, LILACS, Scopus, ClinicalTrials.gov, and the Cochrane Library were searched from inception to July 2020. Selection criteria: Randomized controlled trials (RCTs) concerning women with a singleton vertex pregnancy at term who were treated with PHL. Data collection and analysis: Relevant data were extracted and tabulated. Review Manager 5.3 was used for data analysis. Primary outcome evaluated was the mean reduction of the first stage of labor. Main results: Five RCTs, including 487 pregnant women, were analyzed. The first stage of labor duration was significantly shorter in the treatment arm compared to the control group [MD−113.21 min (95% CI−119.63,–106.79)]. A significant shortening of the second stage was achieved in the PHL group [MD−11.12 min (95% CI−12.64,–9.75)] while no differences were reported for the third stage. Conclusions: PHL might represent an effective treatment to shorten the duration of the first and second stage of labor. Synopsis: A meta‐analysis of 5 trials found that Phloroglucinol favorably impacts on the total duration of the labor in primiparae and multiparae women with a singleton pregnancy.
