In response to the original question of whether or not family should be present during invasive procedures performed on patients--I say absolutely not. I think with family present patients may feel that they have to act a certain way during the procedure, which could add more unecessary stress to the patient. They may feel that they have to be "strong" in front of their family. Also, family does not have the medical background to understand the procedures occuring. I think it would cause great stress and concern for the family to see their loved one going through something invasive that they don't understand. As nurses we give families brief run downs of the procedures to be performed, but do not have time to explain the details, which would be necessary in watching such procedures. Family may become alarmed and distract medical staff from the patient with questions. Hopefully this provides another perspective for you.
