Area of Science:

  • Surgical Engineering
  • Infection Control
  • Air Filtration Technology

Background:

  • Operating room (OR) infections are a significant concern, necessitating advanced air filtration.
  • Traditional laminar airflow (LAF) systems require specific OR configurations, including extra side walls.

Purpose of the Study:

  • To discuss different types of ultraclean laminar airflow (LAF) systems used in operating rooms.
  • To highlight the demands of these LAF systems on OR clothing and team behavior for infection prevention.

Main Methods:

  • Review of existing laminar airflow (LAF) technologies adapted for operating room (OR) environments.
  • Analysis of airstream patterns in traditional vertical/horizontal and new exponential airflow LAF units.
  • Discussion of OR team dressing and behavioral protocols related to LAF systems.

Main Results:

  • New zoned down-flow LAF units utilize exponential airflow, resembling an upside-down trumpet mouth.
  • This exponential airflow technology permits the omission of extra OR side walls, enhancing versatility.
  • Different LAF systems necessitate specific knowledge of airflow dynamics and OR team conduct.

Conclusions:

  • Understanding LAF airstream patterns is crucial for preventing contamination in sterile OR environments.
  • Adherence to specific OR clothing and behavioral guidelines is essential for maximizing the effectiveness of LAF systems.
  • The adoption of versatile, wall-omitting LAF units represents an advancement in OR infection control strategies.
