Bit of a shock

I recently had my cardio placement at SCGH in ICU. Having spoken to many students about this placements i heard that a lot of people had found it quite confronting as the patients are often quite close to death. On starting this placement I found that i had no problems dealing with this fact, as most of the patients are intubated and as such no real relationships were established between the patients and myself. However on one morning my supervisor told me to go and see a patient called Jason. Not expecting anything out of the ordinary I went to the patients bedside and discovered to my shock that it was someone that i knew. It took me a while to be sure because the sedatives totally relaxed the muscles in his face and none of his normal wrinkles were present, however his family had put photos up which confirmed that it was a guy who i knew as "Squiz". Squiz was a regular at a pub that I frequented and although i had never gotten to know his real name i knew him quite well. It was at this point that i bagan to find ICU a bit confronting as now it was someone I knew who was close to death. Fortunately Squiz was doing quite well and looked like recovering but i remember finding it very bizarre to be treating someone i knew. I found it very weird to think that i had done a full treatment but when Squiz woke up he would have no idea that i had been there.
Although quite confronting at the time I'm glad that I was treating Squiz because unlike his other friends who knew very little other than that he was sick, I was lucky enough to have the full picture and could see that he would probably recover. Having said that if the situation had been that he was unlikely to recover i think i would have preferred not to have been treating him.
