Risk of Ocular Transmission of Blood-Borne Contaminants during Orthopedic Surgery a Prospective Study and Literature Review

並列摘要


With rising emergence of transmissible viruses such as HBV and HIV in our community, the relevance in the possibility of gross ocular exposure to blood droplet sprayfrom the patient to the surgeon during different orthopedic surgeries have not been assessed. Hence, from Sept. 1, 1992 to May 31, 1993 we conducted a prospective observational study of blood droplets contamination of the surgeon’s eyewears as a result of back-splash of fluids during our orthopedic operative procedures that are regularly performed at Cardinal Tien Hospital. The purpose of this study is to assess the degree and rate of ocular exposures to blood and fluid droplet contaminants during orthopedic surgery, and to further understand the factors and mechanisms relevant to its occurrence. With this regards, we collected one hundred consecutive cases of different orthopedic procedures and all the eyewears of the operative team are checked immediately at the end of each procedure. We utilized a pencil digitalization copying methods and a mess-match mapping techniques in gathering and analyzing our data. Unfortunately, our study revealed a significantly high incidence with the greastest risk of exposure of the eyes to blood and marrow fat droplets during total knee and hip arhroplasties, and also during open IM nailing of long bone fractures. With the in adequate protection provided by the ordinary reading eyeglasses of the surgeon, we suggest that improved barrier technique such as a closed type eye-shields or facial helmit be adopted into the protocol of major orthopedic procedures.
