Preparing for surgery with Essential Thrombocythemia (ET) taking Hydroxyurea (HU) requires strict collaboration between a hematologist and surgeon to manage bleeding and thrombosis risks. Key steps involve optimizing platelet counts (often via continued or adjusted HU), temporary cessation of blood thinners like aspirin, managing skin hygiene to prevent infection, and utilizing prophylactic measures to prevent post-surgical clots.

Key Pre-Surgery Preparations
Multidisciplinary Consultation: Ensure your surgeon is in close contact with your hematologist to review your CBC (Complete Blood Count) and manage the surgical plan.
Platelet Management: HU is often continued, but dosage may be adjusted, or in some cases, treatments like plateletpheresis may be used to quickly reduce high platelet counts before surgery.
Medication Adjustments: Typically, you will be instructed to stop anti-platelet agents (e.g., aspirin) for about one week prior. Your doctor may modify or switch other medications like Warfarin or similar drugs to heparin, say MPN Voice.
Infection Control: Use chlorhexidine soap/wipes to clean your skin for 3 days before surgery, particularly in areas like underarms and the groin, to reduce bacteria.
Blood Clot Prevention: Because ET increases the risk of clotting, you may receive Heparin post-surgery to prevent blood clots.
Diet and Lifestyle: Stop smoking/alcohol at least 2 weeks prior. Adhere to the "nothing by mouth" (NPO) guidelines provided by the hospital, usually avoiding solid foods after midnight.

Actionable Checklist
Inform all doctors about all medications (including herbs and supplements).
Arrange for someone to pick you up.
Prep a care package for recovery (protein-heavy food, comfortable clothes).
Review with your care team if a platelet-lowering procedure is necessary immediately before surgery.
