New birth calculator should reduce severe obstetric tears
A new study highlighting the risk between bigger babies and obstetric anal sphincter tears should pave the way for better planning for pregnant women to reduce the number of maternal birth injuries, and the subsequent need for Perineal Tear claims.
The research conducted at the University of Gothenburg in Sweden unsurprisingly concluded that high birth weight is the main risk factor for birth injuries to the anal sphincter muscles. We know from clients that such injuries can cause long-term challenges, affecting physical health, relationships and quality of life.
The aim of the study was to develop and validate a prediction model to help assess the risk of OASI in advance of a vaginal delivery. OASI, or Obstetric Anal Sphincter Injury, is a severe type of perineal tear which, if not properly treated, can go on to cause severe health problems for women and affect future pregnancies and birth.
A baby's birth weight was the strongest predictor of OASI in all types of delivery with larger babies increasing the risk of severe vaginal tears. Among women giving birth to their second child vaginally, a previous OASI was a strong indicator of a likely repeat injury. A third risk factor was a ventouse delivery.
When the study results are fed into statistical models, it gives women and clinicians a predictor tool to help them make informed decisions on their pregnancy care and labour choices.
The ultimate aim is of course to reduce the number of injuries to women by implementing the right measures at the right time during their maternity care and birth plan, which may include voluntary caesareans for those at very high risk of repeat perineal tears.
