A recent study in the New England Journal of Medicine found a higher survival of very premature babies — those born between weeks 22 to 24 of gestation — has risen significantly. The study collected data on 4,274 children born in 11 hospitals.

The percentage of premature infants who survived rose from 30% (424 of 1,391 infants) between 2000 and 2003 to 36% in 2008 to 2011. The large majority of survivors were born at 23-24 weeks of gestation. This is medical news with great ethical repercussions, as many doubts arise about whether or not very premature babies should be resuscitated due to the neurological sequelae that many of them suffer.
