English to German Medical Medical (general) Chirurgie

Es geht um einen Arztbericht aus einem amerikanischen Krankenhaus, der behandelnde Chirurg hat nach der OP folgendes verfasst.

Kontext (letzte Schritte der OP):
After closure of the skin, soft dressings were applied. All sponge and needle counts were correct. I was present and SCRUBBED throughout the entirety of the procedure.

Ich habe die folgenden Erläuterungen für "scrub" gefunden, meiner Meinung nach passt aber nichts so richtig:

1. As a verb, to wash the hands and forearms very thoroughly, as before engaging in surgery. To scrub implies the use of a brush (and often an implement to clean under the nails). To scrub, to scrub in (on a surgical procedure), and to scrub up are synonymous.
2. As a noun, a person who scrubs, as for surgery.
3. As an adjective, pertaining to scrubbing in for surgery, as a scrub nurse or a scrub tech.

Vielen Dank vorab.
