A new study has found that some premature babies can survive outside the womb with medical treatment as early as 22 weeks into pregnancy.
The study, published on Wednesday in the New England Journal of Medicine, raises questions about treatment practices for premature babies while also adding a new layer to the abortion debate.
Hospitals vary in how they approach treatment for babies born before 24 weeks, widely viewed to be the minimum age of viability, the New York Times reports. But the study, which analyzed almost 5,000 babies born at between 22 and 27 weeks, found that a small number of babies born at 22 weeks could survive with treatment, some with long-term impairment. Those that were not treated died.
Each year, roughly 5,000 babies are born at 22 or 23 weeks in the US, according to the Times.
