Surgical staff have been traditionally required to scrub their hands for 10 minutes preoperatively, which frequently leads to skin damage. Several studies have demonstrated that scrubbing for 5 minutes reduces bacterial counts as effectively as a 10-minute scrub (117,238,239). In other studies, scrubbing for 2 or 3 minutes reduced bacterial counts to acceptable levels (156,205,207,240,241).
Studies have indicated that a two-stage surgical scrub using an antiseptic detergent, followed by application of an alcohol containing preparation, is effective. For example, an initial 1- or 2-minute scrub with 4% chlorhexidine gluconate or povidone-iodine followed by application of an alcohol-based product has been as effective as a 5-minute scrub with an antiseptic detergent (114,242).
Surgical hand-antisepsis protocols have required personnel to scrub with a brush. But this practice can damage the skin of personnel and result in increased shedding of bacteria from the hands (95,243). Scrubbing with a disposable sponge or combination sponge-brush has reduced bacterial counts on the hands as effectively as scrubbing with a brush (244–246). However, several studies indicate that neither a brush nor a sponge is necessary to reduce bacterial counts on the hands of surgical personnel to acceptable levels
anyways.. interesting distraction...
back to grilled cheezes.
I mean, if you want, we could launch in to a huge discussion about how one properly removes environmental contamination from ones filthy paws...We could get in the nitty gritty of waterless vs. non, brush vs. sponge, contact time, chlorohex vs iodine vs alcohol, whether it even matters given the bacterial load of the air in the OR, the benefits of shoe covers, and laminar flow systems, the importance of nail hygiene, coke or pepsi, diet or regular etc etc... our group had an hour long meeting on it recently, so this topic is rattling around my head ad nauseam ....... but I prefer your grilled cheese porn shots. The six sided method is a lovely thing to behold and your arty black and white photos make it classy porn indeed. BACK TO THE CHEESE!
