[2025-10-01T20:07:42.089284] [PI reasoning] **Evaluating lithium discontinuation before anesthesia**

The user's question focuses on how many days before anesthesia lithium should be stopped, which involves preoperative management. From what I remember, lithium can impact neuromuscular function and heart rhythm. The common recommendation is to discontinue it 24 hours before surgery, but some guidelines suggest waiting up to 72 hours. I feel like consulting anesthesia textbooks for confirmation on this would be a good step!

[2025-10-01T20:08:13.119328] [PI reasoning] **Considering medication guidelines**

I'm not retrieving specific data right now, but I remember that standard guidelines suggest discontinuing certain medications 24 hours prior to surgery, particularly for anesthesia. Texts like "Morgan & Mikhail's Clinical Anesthesiology" recommend this. There’s also a guideline about lithium, which should be discontinued to minimize interactions with neuromuscular blockers. With lithium’s half-life at about 24 hours, stopping it a day before surgery would help ensure safer outcomes. So, I’ll choose option A (1 day).
