hi lilla_fjaril & eeryone. i am rn in australia. in australia we have no technician working in or settings, so we have the choice of working as scrub/scout rn oras anaesthetic rn. i do scrub/scout in 'cvor' - here we call it 'cardiac / cardiothoracic theatres' so no one here would know what cvor means as we are more in tune with the british ways of doing things. in regard to bypass cannulas, we don't rely on perfusionist to tell or hand us cannulas as we manage all of them and we know what our surgeons' preferences are. so it's pretty set routine unless complicated by the patient's anatomy. we always open cannulas to scrub rn & that applicable to all sterile items. we never open sterile items onto sterile tables/trolleys, not even sterile gloves (scrub rn and surgeons recieve their gloves while they're putting on their sterile gowns - they will grab those gloves from scout rn with no fingers exposed). for some of the surgeons we don't even open bypass cannulas and bypass accessories for cabg since these surgeon do a lot of off-pump cabg cases, and i'm sure the same as other surgeons worldwide like to inspect the heart first. if they decide to do on pump cabg then we have individualised emergency bypass box for each surgeons. i have been fortunate in my workplace to not have any issues with other staff members and was well orientated and precepted when first came to cvor with no prior or experience. mainly because we are close knit unit, and very well respected by each other and the surgeons. i am sorry to hear that you haven't had the best welcoming experience into or setting. but hang in there as you a strong person, and soon enough others will realised you effort and contribution to the unit as a valuable team member. best of luck.
