My husband had gall bladder surgery and his gall bladder was filled with puss and he had quite a bit of scare tissue from the infection - he had no symptoms until a few weeks before surgery - he lost 2 units of blood during surgery (2 hours) and his PB dropped (he takes meds for high BP). His blood work showed kidney, liver, white count were all abnormal he also had a bit of confussion and anger. After 6 days he went to rehab but was re-admitted few days later as he had a UTI and was septic and his PB dropped to 57/42 and 02 levels were too low, after 4 days in CCU, with BP back up he went to step down unit and the next day he had a stint put in his small intestine to stop a small leak. The day after stint was put in he was back to his normal self and looked better then he had in several months. Unfortunately the step down unit forgot to resume his lasix ( he complained to them all afternoon that he was having trouble breathing and they said your 02 levels are ok) when I came to see him that night his hand was swollen, I looked at his legs and they were more then twice the normal size, I asked if they had resumed his lasix now that his BP was back to normal range on BP meds and they had not. A chest x-ray showed fluid all around his heart and lungs. After IV lasix and 4 liters of fluid he was much better. Several days later they transferred him to a new rehab center within the same medical network. Unfortunately he has had mental confusion, combativeness, frustration and sadness along with being alert at times ever since he retained too much fluid. Could this all be from the anesthetic?
