[INTRAPARTUM ULTRASOUND - THE FUTURE IS HERE]

Area of Science:

• Obstetrics and Gynecology
• Medical Imaging
• Perinatal Care

Background:

• Traditional digital vaginal examination has limitations in accuracy and patient comfort during labor.
• Intrapartum ultrasound (IPUS) presents a non-invasive, pain-free alternative with potential to reduce infection rates.

Purpose of the Study:

• To review the diverse applications and advantages of intrapartum ultrasound (IPUS) in comparison to digital vaginal examinations.
• To highlight IPUS's superior accuracy in diagnosing fetal head position and station, and its ease of use.

Main Methods:

• Review of existing literature on intrapartum ultrasound applications.
• Comparison of IPUS findings with digital vaginal examination outcomes.
• Description of specific IPUS measurements including head-perineal distance (HPD) and angle of progression (AOP).

Main Results:

• IPUS provides more accurate fetal head position and station assessment than digital vaginal exams.
• Trans-perineal ultrasound effectively measures cervical dilatation and effacement, particularly in specific patient groups.
• IPUS aids in assessing labor progress, pelvic dimensions, and predicting delivery mode.

Conclusions:

• Intrapartum ultrasound is a valuable tool for enhancing labor management and predicting delivery outcomes.
• IPUS offers improved diagnostic accuracy, patient comfort, and clinical decision support during childbirth.
• Further integration of IPUS can optimize obstetric care and potentially improve maternal-fetal outcomes.
