A Dean Health System nurse was called out of surgery so a manager could tell her she was being laid off.

Dean Health says the surgery was minor and the patient wasn't affected, but the manager who summoned the nurse from surgery violated medical protocol.

Dean Health spokesman Paul Pitas says the incident happened at Dean's West Clinic in Madison on Wednesday or Thursday.

The Madison-based health care provider announced Wednesday that it planned to "immediately" lay off 90 employees.

Pitas declined to name the employees involved or what type of surgery the nurse was attending when she was called away.
