Current Evidence for the Use of Laminar Flow in Reducing Infection Rates in Total Joint Arthroplasty

Area of Science:

• Orthopaedic Surgery
• Infection Control
• Hospital Engineering

Background:

• Laminar air flow (LAF) is a standard ventilation method in orthopaedic theatres, particularly for joint arthroplasty.
• Its introduction by Sir John Charnley aimed to minimize airborne contaminants during procedures.

Purpose of the Study:

• To review current literature on the effectiveness of LAF operating theatre ventilation.
• To examine the impact of LAF on preventing post-operative wound infections after total joint arthroplasty.

Main Methods:

• Systematic literature review of studies on LAF ventilation in orthopaedic theatres.
• Analysis of data regarding bacterial and particulate reduction.
• Evaluation of post-operative wound infection rates in relation to LAF use.

Main Results:

• LAF systems effectively reduce airborne bacteria and particulate matter in operating theatres.
• However, current evidence does not demonstrate a conclusive reduction in post-operative wound infections following total joint arthroplasty.

Conclusions:

• While LAF contributes to a cleaner surgical environment, it is not solely sufficient to prevent infections.
• Maintaining strict aseptic techniques, administering prophylactic antibiotics, and ensuring good anesthetic control are critical for reducing surgical site infections in joint arthroplasty.
