Dennis Quaid’s newborn twins were transferred to the intensive care unit after they were mistakenly given an overdose of the drug Heparin at Cedars-Sinai Medical Center in Los Angeles. Thomas Boone Quaid and Zoe Grace Quaid, who were born November 8th, are fighting for their lives after they were given 10,000 unit doses of the blood thinner on Sunday morning and again in the evening. Their usual dose was 10 units. The twins began to “bleed out” after the second dose. The twins were born to Quaid and his third wife, Kimberly, via surrogate. Quaid also has a 17-year-old son with ex-wife Meg Ryan.
