My first time checking on an unconscious pt was different for me. She was total care, cath'd, in diapers, with surgically implanted feeding tube (don't know the technical name). I went in to check her diaper and she was dirty. Her daughter was in the room, talking to me as I went through the at steps of changing her. As I cared for her, I told her what I was doing, as I do with all of my pts. Her daughter had a dumbfounded look on her face. I finished my changing and was getting ready to tell her daughter I'd be back in a little bit to check her again when she finally asked me why I explained the procedure and apologized for cold wipes. I told her that this was something I do with every pt I change and that I wasn't going to treat her mother any different just because she couldn't respond. She looked me in the eyes as her's filled with tears. She said that no one else in the facility talked to her mother like nothing was wrong with her.
A couple of weeks ago, I went in to check her vitals and she had no pulse. I checked radial, femoral, and carotid. I went and told the nurse just as her daughter walked through the door. I accompanied the nurse to the room and she asked her daughter to wait outside. She checked the pt then asked the daughter to come in. She broke the news and I just kind of stood there. The daughter started to cry and that did it for me. Four days a week for four weeks I cared for this woman. I had gotten to the point that I would come in just to check on her then spend a few minutes just talking to her daughter. Yes, I lost it. Yes, it was unprofessional. But I do not regret being human.
Dealing with unconscious pts is nothing to be scared of. Just treat them as you would any other pt. yes, dealing with death can be hard. But in all honesty, as long as you continue to treat them with dignity and respect, you shouldn't have a problem. Remember, she is the same pt you have gotten to know over the past few months. Talk to her the way you normally would. Like a previous poster suggested, read to her, watch TV with her, play some calming music for her. She's still in there. If she liked you conscious, as long as you act normally, she'll like you unconscious. My suggestion would be to do your best to not cry in front of her. It may be hard, and it may involve you having to excuse yourself, but I think showing that kind of emotion could potentially detrimental.
I wish you luck. I know this can't be easy on you. It would eat me alive.
