Sponsor's own description
The second stage of labor, defined as the period from full cervical dilatation to fetal birth, is a critical phase in which maternal pushing techniques may significantly affect maternal and neonatal outcomes (1-5). Evidence indicates that directed Valsalva pushing may be associated with maternal apnea, increased fatigue, pelvic floor injury, and adverse fetal effects, whereas spontaneous pushing with an open glottis supports physiological birth processes (2,5-11). The World Health Organization recommends encouraging women to follow their natural pushing urges and supports the use of open-glottis pushing techniques to promote a positive childbirth experience (12). Vocalization pushing is an open-glottis maneuver involving intentional low-tone sound production during exhalation, which may facilitate pelvic floor relaxation, improve pain management, and enhance the birth experience (9-11). However, evidence regarding the effectiveness of vocalization pushing is limited, and data from Türkiye are lacking. This randomized controlled clinical trial aims to evaluate the effects of vocalization and spontaneous pushing techniques during the second stage of labor on labor duration, pain intensity, perineal trauma, maternal fatigue, and childbirth experience.
