I work in a cath lab where nurses also scrub. This provides a better understanding of what your scrubber needs. I too get very overwhelmed at times with everything that must be done in a short period. I try to get a head start on making sure my scrubber has what he or she needs as soon as I see a lesion. I throw everything on except for the inflator, but keep it ready. Then I look at my anticoagulants/antiplatelets and have doses ready. Then by the time the MD yells for supplies I have most things ready to go. It's all about being able to anticipate what they will need before they ask for it, and that comes with time. Hope that helps.
