Reduction of risk-factors for postoperative infections: prospective study on 200 cataract-patients

Zusammenfassung

Eine der gefürchtetsten Komplikationen von Kataraktoperationen stellt die postoperative Endophthalmitis dar, deren Prognose leider immer noch in vielen Fällen sehr schlecht ist. Die Inzidenz postoperativer Endophthalmitiden liegt derzeit durchschnittlich unter 0.1%. Der Zweck unserer Studie bestand darin, die Effizienz des an der 2. Universitäts-Augenklinik angewendeten Regimes zur Vermeidung intraoperativer Infektionen zu evaluieren. Es wurden daher einerseits vor der Operation Bindehautabstriche abgenommen, andererseits aber auch intraoperativ gewonnene Kammerwasserproben untersucht, um den Grad der Kontamination festzustellen. Alle Operationen wurden von demselben Operateur (G. G.) durchgeführt. Obwohl 75% der präoperativen Abstriche und 25,5% der intraoperativen Proben kontaminiert waren, kam es in keinem Fall zum Auftreten einer postoperativen Endophthalmitis. Dieses, sowie weitere Ergebnisse der Studie werden diskutiert, die verschiedenen Prophylaxe-Maßnahmen werden präsentiert.

Summary

Postoperative endophthalmitis remains one of the most devastating complications of eye surgery. In recent years infections caused by Propionibacterium acnes or coagulase-negative staphylococci have gained in importance. The onset of these infections is protracted and on average the first symptoms develop days to weeks after surgery. 200 patients were included in this study: both preoperative smears of the conjunctiva and intraoperative aspirates of the anterior chamber were taken. All samples were examined for aerob and anaerob microorganisms. 75% of the preoperative smears were contaminated. The most commonly isolated organisms were coagulase-negative staphylococci and staphylococcus aureus. But also 25.5% of the patients had culture-positive anterior chamber aspirates. Inoculum sizes were extremly small (10 to 20 colony-forming-units/ml). In no case postoperative endophthalmitis had taken place. The results of this study are presented, prophylaxis by use of antimicrobial agents is discussed.
