I have been upset for almost two days. All I can think about is replaying the worst thing that has happened to me this far in my nursing career. The other night I had a patient who had a total knee replacement. Everything was fine... Patient requested Ambien for sleep. So I gave the patient 10mg of Ambien. From previous experience with this med, I knew the patient would be out for most of the night if not all of it. Throughout the night, I went in to check the hemovac, a focused assessment. Patient was out! VS normal, etc. Anyways, come early morning about 0600 here comes the doctor. Notices that the patient's arm is flaccid. My poor patient had a stroke throughout the night. I thought the drowsiness/sedation was associated with the ambien, not a stroke. I have put in IV's, catheters, etc. on/in patient's after taking an Ambien without them even waking up. I did not find this one to be any exception. I feel SOOOOO Bad. I keep on replaying everything I saw & did through my head. Has anyone had a terrible event like this happen to them?
