Our er has been doing this for about 2 yrs and it works fairly well. We choose the time for the family member to come in... usually it's when we know that we are going to be unsuccessful in reviving the pt and we want them to see that we did everything possible for their loved one. But in every situation we give the family member the option of going in at one time or another, explaining to them that what they see may be upsetting and graphic. We also have a special room for the family of a code pt called the "family room" which is positioned right next to the trauma room. We have several comfortable chairs, a phone and coffee for them. This all seems to help with our code situations.
