Hi I agree with the rest of your replies. I'm right handed and pass most of my instruments over with my left hand, especially as I'm usually standing beside the surgeon and I was taught not to pass my arm over in front of the surgeon unless it is totally avoidable. Once you find what is comforable for you then it will be like you never had any problems. The other danger with loading scalpel handles with your non dominant hand is that you could slip and injure yourself on the blade, so just be careful, especially with contaminated blades. It just takes practice, practice, practice.... GOOD LUCK :)
