Sentence examples for mean episiotomy angle from inspiring English sources

Mean episiotomy angle, length, depth, incision point.

Only six (16%) women without OASIS had an episiotomy angle <15 or >60°, whereas 143838%) women sustaining OASIS showed an episiotomy angle <15 or >60°.

Considering these two results (26 − 12°), a scarred episiotomy angle of 15° would resemble an episiotomy angle at birth associated with increased risk of obstetric anal sphincter injuries.

On the other hand, a 60° angle will probably resemble an episiotomy angle of >70° at the time of birth.

Further, in an observational study by Andrews et al. episiotomy angle was measured immediately after repair.

We found a 'U-shaped' association between angle and OASIS, suggesting that a scarred episiotomy angle ranging from 30 to 60° imposes the least risk of OASIS.

The investigators theorised that an episiotomy angle of 30° or less would function as a midline incision thus not unload the perineum sufficiently.

Considering shrinkage and changes of perineal tissue after birth, our results support the findings of other clinical studies., Poor correlation between the angle of episiotomy at the time of the cut and the scarred episiotomy angle measured at postnatal visit is reported in two studies.

This was also the case for mean distance d (6 versus 9 mm ) as well as mean episiotomy length e (13 versus 17 mm).

Women in the cases and controls groups where matched for ventouse/forceps because of the strong association between OASIS and instrumental delivery).,, A power calculation using results from Andrews et al. was undertaken for episiotomy angle, with an anticipated difference of 11° between groups, with a standard deviation of 13°, giving a significance level of 5% and power of 90%.
