A Connecticut hospital facing a lawsuit by a woman who says she was severely injured when she fell off an operating table after surgery says it deeply regrets what happened and apologized to the patient.

Attorneys for 81-year-old Florence Fiedler of New Canaan filed the lawsuit Tuesday against Yale-New Haven Hospital.

The lawsuit says Fiedler had a pacemaker implanted in February 2010 and fell off the table after the surgery. Her attorneys say she suffered fractures of the hip and collarbone, a traumatic head injury that resulted in bleeding under her skull and other injuries.

The lawsuit alleges the hospital improperly left Fiedler unattended.

Rob Hutchison, spokesman for Yale-New Haven Hospital, says the hospital promptly reported the incident to the state Department of Public Health.
