Postoperativne infekcije rana i kirurške maske za lice: kontrolirana studija
Ova je studija osmišljena kako bi otkrila 30% ili veću razliku u stopama infekcija rana opće kirurgije korištenjem maski za lice ili ne. Tijekom 115 tjedana u studiju je bilo uključeno ukupno 3088 pacijenata. Nakon 1.537 operacija obavljenih s maskama za lice, zabilježene su 73 (4,7%) infekcije rane, a nakon 1.551 operacije obavljene bez maski za lice, dogodilo se 55 (3,5%) infekcija. Ova razlika nije bila statistički značajna i bakterijske vrste uzgojene iz infekcija rana nisu se ni na koji način razlikovale, što bi potkrijepilo činjenicu da je numerička razlika bila statistički "promašena" razlika. Ovi rezultati pokazuju da bi se korištenje maski za lice moglo ponovno razmotriti. Maske se mogu koristiti za zaštitu operativnog tima od kapi zaražene krvi i infekcija koje se prenose zrakom, ali nije dokazano da štite pacijenta kojeg operira zdravi operativni tim.
Postoperative wound infections and surgical face masks: a controlled study
The present study was designed to reveal any 30% or greater difference in general surgery wound infection rates by using face masks or not. During 115 weeks, a total of 3,088 patients were included in the study. After 1,537 operations performed with face masks, 73 (4.7%) wound infections were recorded and, after 1,551 operations performed without face masks, 55 (3.5%) infections occurred. This difference was not statistically significant and the bacterial species cultured from the wound infections did not differ in any way, which would have supported the fact tha the numerical difference was a statistically "missed" difference. These results indicated that the use of face masks might be reconsidered. Masks may be used to protect the operating team from drops of infected blood and from airborne infections, but have not been proven to protect the patient operated by a healthy operating team.
