Soooo embarrassing. After my hand tremors caused me to contaminate a sterile field while assisting a physician with bedside I and D, I couldn't take it anymore. I now take propanolol er 60mg with pretty good results (most of the time). As for venipuncture, before I stick I warn the patient usually with a joke. "I'm gonna warn you now that my hands shake like I'm on crack. I realize that a nurse with shaky hands coming at you with a garden hose sized needle can be a little disconcerting, but they steady up when it's true business time." Most of the patients are pretty understanding--thank goodness.
