Hi Shannon,Glad your biopsy will be underway soon and you will then know exactly where you are at.
Propofol is not a paralysing agent. It is a sedative /anaesthetic agent and is widely used both as an anaethetic drug and for sedating critically ill ventilated patients. It's the drug that makes you go to sleep . They will however probably use a paralysing agent to ensure your tonsils do not move while they perform the biopsy.
Either way, don't worry as you will be completely unaware.
Keeping my fingers crossed for you,
Tammy
