Bed sores
My 80+ year old family member had a severe stroke and is mostly unconscious. He weighs about 95 kg, has diabetes (blood sugar usually around 120–180 on), is fed through a nasogastric (nose) tube, and cannot move on his own.
He has developed a pressure sore on his upper thigh/hip area (photos attached). There is black tissue and open pink tissue, but currently there is no bad smell, no obvious pus, and the area does not feel hot.
We recently bought an alternating air mattress and are repositioning him as much as we can, but he still seems to be getting more pressure damage. Because he is heavy and unconscious, it is difficult to keep him turned, and he often rolls back flat.
My questions:
Based on the photos, how severe does this look?
What dressings are typically used for wounds like this?
Is the black tissue something that can heal on its own, or does it usually need removal?
How often should we reposition him?
What nutrition is most important for healing, especially with diabetes and tube feeding?
Any practical tips to prevent this from worsening or to stop new sores from forming?
Any advice from wound care nurses, caregivers, or people who have dealt with severe pressure ulcers would be greatly appreciated.
