Years ago when I had surgery and had to go into ICU, it was awful. I had come from recovery and it was late. My husband and son had come in with the doctor and then I fell asleep again. When I awoke the next time and asked for my husband or son, I was told the nurse had sent them home because there was nothing they could do. Home was a good distance away. I felt so alone. Also had a male nurse and this was new for me. My BP was very high and they were having trouble getting it down. I thought the night would never end. Why in the world would a nurse do this? I believe if they had stayed, my BP would have been easier to control. The ICU is a different world and a scary one. I felt so vulnerable. 🙁
