Newly released documents show that Washington Department of Health investigators questioned Seattle Children’s use of an operating room during a cardiac surgery on an infant in early October 2019, according to an article on the King5 website.
That baby later tested positive for Aspergillus infection.
While OR suite #11 had not undergone new construction to add a HEPA filter, several other of the hospital’s operating rooms did have advanced filtration systems.
The hospital said that OR #11 had continued negative air sample results when tested for Aspergillus and that the closure of the OR was creating concerns of workflow issues with caseloads.
