Angle of progression measured with transperineal ultrasound in the second stage of labor for predicting delivery mode:Meta-analysis
Objective To observe the value of angle of progression(AOP)measured with transperineal ultrasound in the second stage of labor for predicting delivery mode using meta-analysis.Methods Articles published in Chinese or English focused on the prediction of delivery mode using AOP measured with ultrasound during the second stage of labor were searched in databases from January 1,2018 to August 31,2023.The literature were screened by 2 researchers according to the inclusion and exclusion criteria,and information were extracted to assess the value of AOP measured in the second stage of labor with transperineal ultrasound for predicting delivery mode.The quality of the included literature were evaluated using Quality Evaluation Tool for Diagnostic Tests-2(QUADAS-2).Results Eleven studies including 2 315 parturient women were enrolled.Meta-analysis showed that the combined sensitivity(Sen),combined specificity(Spe),combined positive likelihood ratio(+LR),combined negative likelihood ratio(-LR),and combined diagnostic ratio(DOR)of AOP measured with transperineal ultrasound in the second stage of labor for predicting delivery mode was 0.80[95％CI(0.76,0.83)],0.83[95％CI(0.78,0.88)],4.8[95％CI(3.5,6.6)],0.24[95％CI(0.20,0.29)]and 20[95％CI(13,30)],respectively,while area under the summary receiver operating characteristic curve of 0.88.Conclusion AOP measured with transperineal ultrasound in the second stage of labor had fine efficiency for predicting delivery mode,which could be regarded as a useful predictor for probability of natural delivery.
