Abstract
WOOG CASTANON, Alberto et al. Maternal and neonatal risk factors associated with obstetric anal sphincter injuries. Acta méd. Grupo Ángeles [online]. 2021, vol.19, n.2, pp.204-207. Epub Nov 23, 2021. ISSN 1870-7203. https://doi.org/10.35366/100443.
Introduction:
Perineal tear is a complication of labor; perineal tears are continuity solutions that may be accompanied by minor bruises, muscle tears, or major lacerations. Perineal tears are subclassified in first degree tears damage to skin; second degree perineal damage muscles; the third degree is subclassified in (A) that covers damage in less than 50% of the external anal sphincter (EAE), (B) more than 50% of EAE without including the internal one and (C) includes the loss of the internal anal sphincter; and the fourth degree includes the anterior and the damage of rectal mucosa.
Objective:
To identify the demographic, obstetric and neonatal characteristics that are related to perineal tears and to identify the risk factors associated with anal sphincter injury.
Material and methods:
Descriptive, retrospective, and observational study with review of the physical database of patients treated at a private hospital in Mexico City, which looked for severe perineal tear in maternal complications, which were compared with moderate perineal tear.
Conclusions:
No risk factor associated with severe perineal tear was found.
Keywords : Perineal tear; severe perineal tear; risk factors for severe perineal tear; obstetric anal sphincter injury.
