MedPage Today (7/13) reports, “Infants in Sweden who did not receive intramuscular vitamin K administration at birth – a small but growing population – had an increased associated risk of bleeding episodes, including intracranial hemorrhage, a nationwide cohort study suggested.” Investigators found that “among more than 2 million live births from 2003 through 2021, infants who went without vitamin K had higher odds of bleeding during the first 6 months of life compared with infants who received vitamin K (adjusted OR [aOR] 1.52, 95% CI 1.27-1.81).” Meanwhile, “for intracranial bleeding, odds were 2.91-fold higher (95% CI 2.13-3.96) among those who did not receive the vitamin K shot.” The findings were published in JAMA Pediatrics.
