Sentence examples for midline episiotomy from inspiring English sources

The purpose of this study was to determine the impact of operative vaginal delivery (forceps or vacuum) and midline episiotomy on the risk of severe perineal trauma.

This study was undertaken to estimate the reliability and validity of an objective structured assessment of technical skills (OSATS) for midline episiotomy repair using a lifelike anatomic model.

The purpose of this study was to determine whether selective midline episiotomy contributes to the prevention of third- or fourth-degree perineal lacerations.

Study design: Among 20,111 consecutive vaginal deliveries, where midline episiotomy was not performed, 342 (1.7%) third degree tears occurred, significantly more often in primiparae (2.9%) than multiparae (0.8%; P<0.001), all of whom underwent postpartum anal manometry and endosonography.

The performance of a midline episiotomy was associated with an increased risk of anal sphincter tear compared with delivery without an episiotomy in the univariate analysis (odds ratio, 4.9; 95% CI, 2.5-9.6), buthisis association was reduced in the adjusted analysis (odds ratio, 2.5; 95% CI, 1.0-6.0).

When considering the geometric structure of the midline, vaginal opening, episiotomy incision point and episiotomy length, the characteristic depth b is perhaps the most explanatory because it is a function of lengths d and e and angle α.

7 However, further, large observational studies have suggested that although the midline type of episiotomy is associated with increased OASIS risk, 8 the mediolateral episiotomy technique is associated with substantially decreased OASIS risk.

Episiotomy length, e, was defined as the length from the outer rim of the labia, fully exposed, but not excessively stretched and angle, the angle between a (midline) and the episiotomy.
