Abstract

Objective: To investigate the manipulative reduction in abnormal uterine inclination in vaginal delivery.

Methods: With the independently developed uterine inclination surveyor, 40 primiparas with abnormal uterine inclination were randomly divided into two groups: treatment group (Group A, 20 cases) and control group (Group B, 20 cases). The general condition of the primipara, the labor stages, the changes in uterine inclination after treatment, postpartum hemorrhage at 2 hours, and the general condition of fetuses were observed to study the therapeutic value of manual reduction in abnormal uterine inclination.

Result: In the control group, one uterine inclination was not corrected with the change in labor process, and the pregnancy was terminated due to stagnation of the active phase. In the first stage of labor, the time spent in the treatment group (393.4 ± 31.3 mins) was significantly lower than that in the control group (440.7 ± 34.9 mins) (P = 0.001). Compared with the control group (49.8 ± 6.5 mins), the treatment group (42.6 ± 7.2 mins) also exhibited a significantly shortened second stage of labor (P = 0.02). Sixteen cases (16/20) in the treatment group returned to normal after manual reduction, and 9 cases (9/20) in the control group returned to normal with the progression of natural labor. Manual reduction could be used as an option to treat abnormal uterine inclination (P = 0.01). There was no significant difference in the third stage of labor (P = 0.2), 2-hour postpartum hemorrhage (P = 0.35), Apgar score (P = 0.64), or body weight (P = 0.76) between the two groups.

Conclusion: Manual reduction in the treatment of abnormal uterine inclination has obvious effects, shortens the birth process, and is safe for the fetus.

Projection of the human body at the uterine inclination. Point O is the upper edge of the pubic symphysis, point A is the point below the anterior midline xiphoid, and point B is the actual uterine floor position. Line OA is the midline of the human body, line OB is the longitudinal axis of the uterus, and the angle α is the uterine inclination as defined in this study.
