Dennis Quaid's Babes Fight For Life

Dennis Quaid and wife Kimberly Quaid are keeping vigil.

Their new-born twins are still seriously ill.

But the couple have released a statement thanking fans for their support.

His rep said: "Dennis and Kimberly appreciate everyone's thoughts and prayers and hope they can maintain their privacy at this difficult time."

Twelve-day-old Thomas Boone and Zoe Grace were taken into intensive care after they were reportedly given an accidental overdose of an anticoagulant - which stops blood from clotting, after the drug was stored incorrectly at the Cedars-Sinai hospital in LA.

The Cedars-Sinai chief medical officer Dr Michael Langberg confirmed that "as a result of a preventable error" three patients who were being treated intravenously had their IV catheters accidentally flushed with a 10,000-unit solution of heparin, rather than the prescribed 10-unit dose.

"The error was identified by Cedars-Sinai staff, who immediately performed blood tests on the patients to measure blood clotting function.

"I want to extend my deepest apologies to the families who were affected by this situation, and we will continue to work with them on any concerns or questions they may have."?
