Abstract

We prospectively evaluated PPS contamination in 61 primary THAs and 41 TKAs The PPS were assumed to be sterile before opening the packs The initial culture was taken immediately after the hood was placed over the helmet Four cultures were collected at the conclusion of the procedure Plates were examined and colonies were classified according to Gram stain results and biochemical tests S aureus was classified as methicillinresistant or susceptibleAt time zero 22 of 102 cultures isolated an organism accounting for a contamination rate of 22 The bacterial contamination rate of the PPS at the conclusion of the procedure was 47 48 of 102 The relative percentage of the various organisms found was coagulasenegative staphylococci 50 Micrococcus sp 20 methicillinsusceptible S aureus 11 and methicillinresistant S aureus MRSA 1The external surface of the PPS cannot be assumed to be sterile after its removal from the original packaging Of all the PPS studied the potential pathogens coagulasenegative staphylococcus S aureus and MRSA were found in 43 This study supports the need to change gloves if the PPS is touched or adjusted during the procedure
