Factors for prenatal ultrasound parameters of prolonged second stage of labor
At present,domestic and foreign scholars have conducted in-depth discussions and studies on prenatal ultrasound and the duration of the second stage of labor respectively,which greatly promoted the development of medi-cine.Studies have found that prolonged second labor is strongly associated with increased maternal and neonatal compli-cations;however,predicting the risk of prolonged second labor in a clinical setting is difficult.At present,there are few studies on the correlation between prenatal ultrasound and the duration of the second stage of labor.Therefore,prenatal abdominal ultrasonography combined with perineal ultrasonography for fetal examination is necessary to fully understand the risk factors associated with the prolonged second stage of labor and formulate appropriate treatment strategies,which can help clinicians make timely diagnosis and reduce the incidence of adverse prognosis.This article reviews the relation-ship between prenatal ultrasound parameters and the prolngation of the second stage of labor.
