Ventilation systems are the primary way of eliminating airborne pathogenic particles in an
operating room (OR). However, such systems can be complex due to factors such as …

Periprosthetic joint infection (PJI) has moved into the first place as the cause of failure
following total knee arthroplasty (TKA). Recent studies have shown that PJI results in higher …

Aim To evaluate three types of ventilation systems for operating rooms with respect to air
cleanliness [in colony-forming units (cfu/m 3)], energy consumption and comfort of working …

Introduction Laminar airflow (LAF) systems are thought to minimise contamination of the
surgical field with airborne microbes and thus to contribute to reducing surgical site …

Objectives To evaluate (1) the relationship between heating, ventilation, and air conditioning
(HVAC) systems and bioaerosol concentrations in hospital rooms, and (2) the effectiveness …

In this study, a systematic procedure for establishing the relationship between particulate
matter (PM) and microbial counts in four operating rooms (ORs) was developed. The ORs …

Abstract Background Operating rooms (ORs) are usually over-pressurized in order to
prevent the penetration of contaminated air and the consequent risk of surgical site infection …

Background The importance of laminar airflow systems in operating rooms as protection
from surgical site infections has been questioned. The aim of our study was to explore the …

Air cleanliness in operating theatres (OTs) is an important factor for preserving the health of
both the patient and the medical staff. Particle contamination in OTs depends mainly on the …

Highlights•Door openings are correlated with bacterial contamination in the operating
room.•Vertical laminar airflow (LAF) reduces the negative effects of door openings.•Number …
