Corpus Christi, TX-based Christus Spohn Hospital South is investigating how up to 17 babies in a neonatal intensive care unit received overdoses of the blood thinner heparin. One of the babies died, and nursing staff at the hospital discovered the problem two days after the medication is believed to have been first administered. Heparin came into the public spotlight in 2007 when newborn twins of actor Dennis Quaid nearly died after receiving an overdose at a Los Angeles hospital.
