Airborne bacteria pose hidden threat in cardiac ORs, study warns
Editor's Note Air quality in cardiac ORs may be a silent driver of surgical site infections (SSIs), with airborne contamination linked to significantly elevated infection risk and mortality—especially when ventilation is suboptimal. A newly published study covered by Medical Dialogues May 19 reveals that one-third of bacteria in cardiac procedures…
Bioburden levels during total joints in ORs complying with US ventilation specifications
Editor's Note This study from Baptist Health-Fort Smith, Arkansas, finds that the low-energy consumption ventilation system specified for in US operating rooms produces different zones of sterile protection from airborne microbe carrying particles (MCP) during total joint arthroplasties. The predominant source of MCPs are from personnel in the OR—an average…
Study: Better OR ventilation linked to lower SSI rates
Editor's Note This Swiss study finds that better OR ventilation properties, as assessed with a new ventilation index, are associated with lower rates of surgical site infections (SSIs) in orthopedic, spine, and cardiac procedures. Researchers calculated a ventilation index with higher values reflecting less turbulent air displacement instead of comparing…
