You may wonder why we pull back into the syringe when giving injections in the vein. This picture explains why. We don't pull back to make sure we're in the vessel, we do it to make sure we're in the RIGHT vessel. Today I went to give an injection and pulled back and saw blood brighter than I wanted. I decided to go and get a new dose of sedation and once again pulled back and then gave my dose of sedation. The syringe on the left was my first injection and the syringe on the right was my second injection. Does anyone know why I shouldn't have injected that first syringe? And had I injected that first injection, what would have happened?
