Five weeks ago, my partner sustained a major trauma, when he fell down some steps and basically impaled himself on a broken glass bottle from the shopping he had been carrying, causing him to be partially disemboweled. He had emergency surgery to stem the bleeding, remove part of his damaged small intestine and repair the damage to his liver, then a second operation three days later to rejoin his small intestine and generally tidy up after the first operation. A CT scan confirmed that he had not sustained any head injuries. He was placed in an induced coma in the ICU for two weeks, during which he succumbed to aspiration pneumonia and a further infection in his bowel. He did not initially respond to antibiotics and the doctors expressed serious concern that he might die. He was given a tracheotomy after around 12 days, whereafter his sedation was reduced. He did not, however, begin to wake up for another 12 days or so, and after being transferred to a general ward one week ago, he remains very dazed and confused. For example, when I spoke with him this morning, he was convinced that he had just played a gig - he is a musician - and was waiting to be paid. He had no concept that he was in hospital and refused to be persuaded that this was the case, becoming very irritated in the process. Is this normal, and how long is this likely to last? As I said, he did not sustain a head injury, as has been reconfirmed by further scans.
