When you opt out an expert, it isn't possible to ask them a follow-up question.
I am also having difficulty reading your question and trying to determine what you are asking, but let me try to see if I can help with some of the answers.
Propofol is usually competely out of the body within 24-48 hours, leaving no after-effects.
Narcotics can cause constipation, and both narcotics and propofol can cause restlessness, nausea, and fatigue. Neither causes pain.
Low sodium (hyponatremia) is not a consequence of using any of the drugs you mentioned. Its symptoms are primarily neurological, and may be responsible for some (or even all) of the restlessness. Sodium levels vary for a lot of different reasons. Among them are 1) reduced intake from food; 2) increased loss from urine, diarrhea, sweating; and 3) dilution due to chronic renal problems (renal insufficiency, nephrotic syndrome, or SIADH.
Another possible problem is pseudohyponatremia (it looks like hyponatremia but isn't). This is caused often by high triglycerides or less often by high levels of serum proteins.
No treatment is generally necessary for pseudohyponatremia. If aggressive treatment for hyponatremia is given, it often causes rebound hypernatremia (high sodium). Any additional sodium must be given very judiciously while the cause of the pseudohyponatremia is investigated.
Please let me know if you have other questions.
