Fasting Before Carpal Tunnel Surgery
Carpal tunnel release frees a trapped nerve at the wrist. Many people have it 'wide awake' under local anesthetic only — and that changes whether you need to fast at all. The key is knowing which kind of anesthesia you're booked for.

Medicines to check
- Blood thinners (aspirin, clopidogrel, warfarin, Eliquis, Xarelto) — even for a small hand operation these matter; ask about timing. See medications to stop.
- Diabetes medicines & insulin — if you must fast, you need a plan. See diabetes tablets.
- Blood pressure medicines — usually continued; confirm with a sip of water.
When this surgery may be delayed
- Fever, a new cough/cold, or a chest infection
- Vomiting or diarrhea
- Very high blood pressure or blood sugar
- You ate or drank outside your fasting window
- A skin infection, cut, or rash on the hand or wrist
Reports & documents to carry
- Photo ID and insurance card
- A written list of all your medicines and doses
- Any blood tests, ECG, or scans your team asked for
- Consent forms or referral letters, and allergy details
- Your nerve conduction study report if you have one
What to ask your anesthesia team
- Is my surgery under local anesthetic only, sedation, or general anesthesia?
- If it's local only, can I eat and drink normally beforehand?
- Can I drive myself home, or do I need someone?
- Which medicines do I take or hold?

Frequently asked questions
Do I need to fast for carpal tunnel surgery?
Often not — if it's done under local anesthetic only, many centers let you eat and drink as normal. But if you're having sedation or general anesthesia, you must fast (solids ~8 hours, clear liquids ~2 hours before). Always confirm your anesthesia type with your team.
Will I be awake during carpal tunnel release?
Usually yes. 'Wide-awake' local anesthetic surgery means your hand is numbed but you're fully awake and comfortable. You may feel pushing or pressure but not pain. Some people choose sedation or general anesthesia, which then requires fasting.
Can I drive home after carpal tunnel surgery?
If it was local anesthetic only, some people can — but your hand will be bandaged, so it's often easier to arrange a lift. After sedation or general anesthesia you must not drive and need a responsible adult to take you home.
