Kernaussagen

Früher wurde häufig angenommen, dass spezielle raumlufttechnische Anlagen mit laminarer oder turbulenzarmer gefilterter Luft das Risiko der Entstehung von postoperativen Wundinfektionen reduzieren können.

Die Ergebnisse der vorliegenden Kohortenstudien, bei denen die Operationen unter Alltagsbedingungen durchgeführt wurden, zeigen jedoch keinen Hinweis auf den infektionspräventiven Effekt dieser Anlagen.

Es gibt sogar starke Hinweise, dass LAF das Wundinfektionsrisiko bei den orthopädischen Operationen mit Einsatz von Endoprothesen erhöht.

Die Daten zeigen, dass die Ergebnisse von einzelnen, alten, randomisierten, kontrollierten Studien (Efficacy Studies) nicht immer unbedingt auf die Alltagsbedingungen zu übertragen sind. Es sollte immer untersucht werden, ob sich der günstige Effekt einer medizinischen Maßnahme auch unter Alltagsbedingungen reproduzieren lässt (Effectiveness Studies).
