Risk factors associated with severe perineal tear at Public Hospitals in Bahir Dar town, Northwest Ethiopia.

The proportion of birth-related severe perineal tears was high at governmental hospitals in Bahir Dar town. Previous history of perineal tear, work experience of birth attendants, duration of the second stage of labor, being nullipara, and occipito-posterior position were the major determinants of severe perineal tear. This study suggests that strategies and regulations should be developed to shorten the second stage of labor.
