I am sorry to hear of your husband's painful illness, and of the effects it has had on you all in different ways.How drained you must all feel after such an intense few months. Perhaps your hospital or specialists may be able to refer your husband to an Occupational Therapist who could assess and discuss his current needs for safety and assistance? Perhaps hiring a bed rail from an equipment supplier may help interrupt night time walking? I am not familiar with burns care, but the fluid loss and delirium and wakefulness sound like issues that require ongoing, careful medical advice and oversight. Perhaps you could ring a major hospital's health advice line for some immediate direction or request some community nursing visits? I hope you have people around that are able to encourage and support you all. If people offer to help perhaps they can sit and chat with your husband while you get some rest or respite for a little while each day.My Mum had a stay in hospital recently where her mobility,alertness and safety were an issue. We took turns to sleep by her bedside, sleeping lightly to be ready for her if she made a move to get out of bed, very thankful for the hospital bed rails. It wasn't easy nor sustainable, and I feel for you if this sounds like an ongoing reality in your home. Thankfully some medication changes improved her mobility issues and she is home. Dad takes care to make sure she is fairly central to their shared bed, and they do have a small bed rail. Although he does still sleep fairly lightly, he is fortunate that her night time waking has become less frequent and more predictable, which has made it easier.Praying you get good rest and medical direction soon.
