Fasting Before Trigger Finger Release Surgery

Fasting for this procedure

Most trigger finger releases are done under local anaesthetic — a small injection numbs just the base of the affected finger and palm, you stay fully awake, and in that case you do not need to fast at all and can eat and drink normally beforehand. Fasting only becomes necessary if your team has planned sedation or a general anaesthetic (more likely if several fingers are being released, if it is being combined with another procedure, or if you would prefer to be asleep). If that is the plan, follow the standard rule: stop solid food about 6 hours before your arrival time and stop clear fluids about 2 hours before. Because the answer flips depending on the anaesthetic, never assume — confirm with the booking team which type you are having so you arrive prepared either way. For children having this done, use the child fasting calculator and the 6-4-2 rule (food and formula 6 hours, breast milk 4 hours, clear fluids 2 hours).

Medicines to check

Most regular medicines should be taken as normal with a small sip of water, even on the morning of a local-anaesthetic case — but tell the team everything you take.

Blood thinners are often continued for small hand operations like this one, because the surgery is superficial and bleeding is easy to control with a tourniquet and pressure. Do not stop yours on your own — check the medications to stop before surgery guide and confirm with your surgeon, as some surgeons still prefer to pause warfarin or newer anticoagulants.

If you take clopidogrel, apixaban, rivaroxaban, dabigatran or warfarin, ask specifically whether to continue or hold it, and whether you need an INR check beforehand if you are on warfarin.

If you have diabetes, read diabetes tablets before surgery — for a local-anaesthetic case where you are eating normally you usually take your tablets and insulin as usual, but the advice changes if you are fasting for sedation or a general anaesthetic.

Bring a written list of all tablets, inhalers, patches and supplements with their doses, including anything you buy without a prescription such as fish oil or high-dose vitamin E.

Mention any steroid injections you have already had into the finger, as repeated steroid use can affect the skin and tendon and is useful for the surgeon to know.

When this surgery may be delayed

Active infection or broken skin on the hand or finger — an operation through inflamed or infected skin risks a deeper wound infection, so it is usually postponed until the skin is healthy.

You ate or drank when you were booked for sedation or a general anaesthetic — if fasting instructions were missed, the case is delayed for safety to protect your lungs.

A recent chest infection, cold or COVID — relevant mainly if you are being sedated or put to sleep, as airway irritation raises anaesthetic risk.

Poorly controlled blood sugar or very high blood pressure picked up on the day, which the team may want optimised first.

Confusion over your blood thinner — if it is unclear whether it was correctly continued or stopped, the surgeon may defer rather than risk a bleed or a clot.

Reports & documents to carry

Your appointment letter or booking confirmation, which usually states whether it is local anaesthetic or sedation/general.

A complete list of your medicines with doses, plus your blood thinner and diabetes details.

Any recent blood test or INR results if you take warfarin, and any pre-assessment paperwork you were given.

Details of previous steroid injections or hand procedures on the same finger, if you have records.

Your glasses, hearing aids and a form of ID, and the name of someone who can collect you if you have sedation or a general anaesthetic.

What to ask your anesthesia team

Am I having local anaesthetic, sedation or a general anaesthetic? — this single answer tells you whether you need to fast.

Should I continue my blood thinner or stop it, and if stopping, exactly when should the last dose be?

Will I have stitches that need removing, and how long should I keep the dressing dry?

How much can I use the hand afterwards — when can I drive, type, lift, or get the wound wet?

If it is a local-anaesthetic case, can I drive myself home, or will the numb hand and dressing mean I need a lift?

Frequently asked questions

Do I really not need to fast for trigger finger surgery?

If your operation is under local anaesthetic — which is the most common way it is done — then correct, you do not need to fast and should eat and drink normally so you do not feel faint. Fasting is only required if you are having sedation or a general anaesthetic. Because the plan can vary, always confirm your anaesthetic type with the booking team rather than guessing, so you turn up prepared for whichever applies.

Can I keep taking my blood thinner before a trigger finger release?

Often yes. Trigger finger release is a small, superficial operation and bleeding is easily controlled with a tourniquet and simple pressure, so many surgeons continue blood thinners rather than risk a clot by stopping them. However, practice varies and some still prefer to pause warfarin or newer anticoagulants. Never stop on your own — check the medications guide and get a clear instruction from your surgeon, including whether you need an INR test first.

What will my hand be like straight after the operation?

Expect a bulky dressing over the palm and a finger that feels numb for a few hours while the local anaesthetic wears off, then some soreness as it does. You can usually move the finger gently almost straight away, which actually helps prevent stiffness, but keep the dressing clean and dry. Avoid heavy gripping, lifting and getting the wound wet until your team says the skin has healed, typically once any stitches are out.

Will I be able to drive myself home?

If you had a local anaesthetic only, you may be allowed to drive, but a numb, bandaged hand can make safely controlling the car difficult, so many people arrange a lift for the first journey. If you had any sedation or a general anaesthetic, you must not drive that day and should have a responsible adult collect you and stay with you overnight. Ask your team what they advise for your specific dressing and anaesthetic.
