Actually, most of the time where I work we all get along pretty well. We all have a job to do. But, arrogance can go both ways. I've know some snotty RNs but I've also known some techs who have a huge chip on their shoulder and who try to run the show. Trust me, there are days where i wish i hadn't become a nurse, so I could just focus on the incision and the instruments and not have to juggle everything.
If there's lack of respect on this thread- it's coming from both groups. For example, there little comments about nurses contaminating themselves,or getting no exposure to the OR in NS. By the way, that's not true of all programs. And, for every surgical tech that went through a degree program there's two more that got pulled from another floor and trained to scrub in 8 weeks( several young techs at my hospital like this) or got OTJ training.
The original question got lost along the way... you're not ever going to see STs taking over nursing roles, IMHO. Just woldn't be safe.
