Columbia, SC (WLTX) - Veteran's Affairs officials say they've found particulate matter again in the Dorn VA Hospital's operating room.
Veterans affairs officials said Friday a staff member discovered the matter Thursday.
Because of the problem, Dorn halted their operating room services to protect patients and staff.
While they say they are going to investigate the cause of the problem, they believe it's another breakdown of the air handling system inside the O.R.
"Our sincerest apologies go out to our Veterans and their families," the agency said in a statement. "We are doing our utmost to investigate the cause of the incident and take the proper corrective action for the care of our Veterans is our number one priority."
Back on October 18th, an employee found particulate matter in the operating room, and surgeries were stopped as a result.
The hospital says a disintegrated HEPA filter caused the problem and a professional cleaning crew was hired to clean the operating rooms. While fixing the filter, crews also noticed problems with heating coils in the air system that needed to be fixed.
The operating rooms were reopened on December 2nd. Since it reopened, Dorn VA performed 40 procedures with no debris identified.
Veterans affairs officials say general surgery cases will be referred or rescheduled once the operating room begins service again.
