Six months after particulate matter on surgical equipment temporarily stopped surgeries at the Veterans Affairs hospital in Ann Arbor, Mich., concerns are being raised again, with surgeries being moved or delayed, according to an article on the Detroit Free Press website.
Intermittent problems with particulate matter being found on surgical equipment trays or cases continue, according to a hospital spokesperson.
The hospital did not identify the cause of the particulate matter.
No surgical tools themselves were contaminated in the initial instance but particulate matter led to worries about maintaining a sterile surgical environment.
