二甲双胍、缬沙坦、阿司匹林，三种药三种停法，一个病例带你梳理清晰

TL;DR - A clinical case study promotes DrSeek as an evidence-oriented assistant for translating perioperative medication guidelines into an actionable timeline. It illustrates how the tool supports—but does not replace—multidisciplinary clinical judgment.

• Metformin is stopped on the day of elective surgery and typically resumed after about 48 hours once oral intake and renal function are stable.
• Valsartan is withheld 24 hours preoperatively to reduce anesthesia-related hypotension and restarted when blood pressure and oral intake stabilize.
• Aspirin management depends on its indication: primary prevention generally permits a 7–10-day hold, while secondary prevention or coronary stents require specialist consultation and earlier resumption.
• DrSeek also flags renal function, potassium, blood pressure, glucose targets, and the acute kidney injury risk of combining NSAIDs with an ARB.
