    Dear all,
    There has been recent studies disputing the use of laminar air flow in theatres and some indicating its contribution to severe surgical site infections…
    I’m interested to find out if anyone’s looked into this in further detail and if anyone’s implemented any changes to their current or future theatre designs?
    I’m aware that current building guidelines recommend laminar flow systems but is this now due for a review based on what’s being published?
    Keen to hear everyone’s comments.
    Cheers,
    Gerald

    Dear Gerald,

    The group from Petra Gastmeier from Germany has published some articles around this:

    http://www.ncbi.nlm.nih.gov/pubmed/22011537

    http://www.ncbi.nlm.nih.gov/pubmed/18948793

    http://www.ncbi.nlm.nih.gov/pubmed/22579079

    http://www.ncbi.nlm.nih.gov/pubmed/22828870

    and also Nicholas Graves’ group from Queensland:

    http://www.ncbi.nlm.nih.gov/pubmed/23434381

    http://www.ncbi.nlm.nih.gov/pubmed/22999770

    And it was also discussed at the recent ICPIC Infection Control meeting in Switzerland.

    It now increasingly looks like laminar flow is probably not necessary in operating theatres, but of course, HEPA filtration continues to be.

    Best regards, Matthias.

    Perfect timing, Matthias.
    Thanks.
    I was just about to hunt for Nick’s articles… appreciate the links.
    Have your Singapore hospitals moved to a conventional system with HEPA or are planning to?
    For that matter, has anyone within Australia planned for conventional HEPA filtered air for their theatres?
    If I’m not mistaken (read it somewhere), there may be an alternative system called HEPA filtered turbulent air (???) and I’m wondering if this utilises the same technology of blade-pattern air vents that apparently disperse air around the ceiling and away from the patient below?
    Cheers,
    Gerald
