Actor Dennis Quaid has filed a lawsuit against Baxter Healthcare Corp. The suit claims similar blood thinners, Heparin and a less potent drug caused a mix- up at Cedars-Sinai Medical Center threatening the lives of his newborn twins. The lawsuit was filed in Los Angeles Superior Court on behalf of his children. The Quaid twins were both administered multiple near-fatal doses of Heparin to treat staph infections, according to the lawsuit. The children, Zoe Grace and Thomas Boone, were given 10,000 units of Heparin, rather than the 10 units of Hep-Lock they were prescribed, according to the Complaint. Baxter Healthcare should have recalled the vials ofHeparin containing 10,000 units because the company knew infants had died because of similar medication errors, according to the lawsuit. The children suffered internal injuries and shock, but the extent of what happened to them will probably not be known for years.
