Ultrasonic Characteristics of Diastasis Recti Abdominis in Early Postpartum

Objective. Explore the ultrasound characteristics of early postpartum Diastasis Recti Abdominis (DRA) and provide effective data support for its clinical diagnosis and treatment. Method. A total of 458 parturients who were diagnosed with DRA in the Chongqing Maternal and Child Health Hospital from December 2017 to September 2020 underwent postpartum ultrasound examinations. All of which were located at four points: 6 cm above the umbilicus (point 1), 3 cm above the umbilicus (point 2), umbilicus (point 3), and 3 cm below the umbilicus (point 4) to detect the interrectus distance (IRD) in the resting and sit-up state of the parturients postpartum and to study the differences in maternal age, weight, and ultrasound diagnosis of IRD at different stages after delivery. Results. The IRD values of the four measurement points in the resting state of the parturient were significantly greater than the IRD values in the sit-up state. And in the resting state, the IRD value ( 4.31 ± 1.07   cm ) of the point 3 region was the largest, and there were significant differences at different stages of the postpartum women. At the same time, the IRD values of points 3 and 4 have significant differences in parturient of different ages. In addition, the IRD values of the four measurement points of overweight women were higher than those of nonoverweight women. Conclusion. The umbilicus is the best ultrasound evaluation point for early postpartum DRA. The IRD value at this point in the resting state can be used as reference data for evaluating early postpartum DRA, which provides a useful reference for rapid postpartum recovery of parturients.
