New Surgical Airflow System Will Contribute to the Reduction of Hospital-Acquired Infections

Lanham, MD – Doctors Community Hospital’s new surgical services suite will feature an advanced modular airflow system – the only such system on the east coast.  During surgeries, this advanced technology will sweep particles away from wound sites – ejecting them from the sterile surgical area and trapping them in high efficiency particulate air (HEPA) filters.  Studies have shown that this process is an effective means of preventing micro-organisms from affecting wounds or work surfaces during surgeries. As a result, surgical site infections can be reduced.

According to the Centers of Disease Control and Prevention, the staphylococcus aureus bacteria are the leading causes of hospital-acquired infections.  It is the primary cause of lower respiratory tract and surgical site infections.  Also, they can be difficult to treat because of evolved resistance to antimicrobial drugs. One such type is methicillin-resistant staphylococcus aureus also known as MRSA.

As part of its new surgical services renovation, Doctors Community Hospital acquired Guardian’s Laminar Airflow System.  Requiring no ceiling to support it, this advanced modular system is arranged to form one continuous and seamless array of laminar airflow modules.  Computer simulations of Guardian’s system  shows how it directs air in one direction (downward) from the point it leaves the HEPA filtered system to below table level, sweeping away any airborne contaminants.  With traditional air flow ceilings, gaps in their structures sometimes form backdrafts that may cause turbulent regions in the sterile surgical field, which may draw contaminated air from around the perimeter. 

By effectively controlling airborne particles and preventing them from migrating to the wound site or landing on work tables, the chances of surgical site infections can be reduced.  Creating the cleanest sterile surgical field with the lowest overall energy footprint, this system offers both the highest performance and user flexibility.  According to Paul Grenaldo, chief operating officer at Doctors Community Hospital, “The care and safety of our patients are at the center of the hospital’s nearly 40-year tradition in the community.  When the new surgical services suite opens within the next few months, this advanced airflow system will contribute to our providing more residents with high-quality care to address complex medical conditions.”
