Hi,
How is your dad feeling now?
When did his symptoms start? What are his symptoms?
Some patients can have post-operative delusion depending upon the type of anesthesia and the drug used. The effect will gradually wean off.
You can discuss with the surgeon and anesthetist regarding the symptoms if it persist for long.
Keep me informed if you have any queries.
Bye.
