A 72-year-old woman has suffered burns after a fire ignited while she was undergoing a procedure in a surgical theatre at a Melbourne hospital.
The blaze began when medical equipment malfunctioned at Sunshine Hospital just after 9am on Monday.
It was contained by staff and the Metropolitan Fire Brigade.
Western Health is investigating the cause of the accident and has offered support to the woman's family and staff.
The health service's chief medical officer Paul Eleftheriou described it as a "tragic incident".
"The patient, who suffered burns injuries, was treated immediately at Sunshine Hospital before being transferred to a specialist burns unit," Dr Eleftheriou said.
"Our thoughts are with the patient and their family. Western Health is offering support to the family."
