Summary

The purpose of this paper is to study the effectiveness of a surgical horizontal filtered air flow unit on air and total hip replacement (THR) wound contamination.

Unidirectional air flow consists of air that has been driven through high efficacy 0.3 μ particle retaining filters (HEPA filters) and then directed through a grit in such a fashion that there is low turbulence and the air moves “en block”.

The conclusions of the study, which has been carried out in three groups of cases, are the following:

  1. 1.

    The air near the wound, when the air flow is used, is significantly cleaner.

  2. 2.

    The wounds at the end of the procedure, if the air flow is used, are significently less contaminated.
