What should you do while waiting for someone in surgery?

While someone is in surgery, make sure the hospital can reach you, then look after yourself in small, finishable pieces: water, food, a short walk, one call, one short task for your hands. You cannot speed the operation up. You can make the waiting easier to get through.

This page is a plain plan for those hours, written by a small puzzle studio. We are not clinicians, and the hospital team is always the right source for anything about the patient.

A letter from the waiting room

The board said In procedure at 10:12. By 10:40 you have read the same news headline four times and refreshed it twice more. Your coffee is cold. The television in the corner is showing a cooking show nobody chose.

So you do the small things. You walk to the desk and check they have your number. You text your sister one line: "Started at ten, no news is normal." You buy a muffin you do not want and eat half of it anyway.

Then, back in the chair, you open a puzzle. Sixteen tiles, four target sums. Your thumb finds a path: 2, 1, 1, 1, 1, 6, 4. Sixteen. An amber ring locks. For four minutes your mind has exactly one job, and it is a job you can finish.

When your phone buzzes at 11:55, you close the app mid-thread. It will keep your place. You do not need it to.

Your waiting plan, hour by hour

How long did the team say to expect? Pick one. Times are estimates, so the plan bends.

    How updates usually reach families

    Every hospital does this differently, so the first job is to ask. Some use a screen with a patient number, some a volunteer desk, some a nurse who calls you. At Memorial Sloan Kettering, for example, a nurse liaison "will call a family member's cellphone to give an update," and the family guide asks visitors to bring a charger (MSK, updated July 24, 2026). The same guide says surgeries are sometimes delayed and that staff try to tell families when that happens.

    No news during surgery usually just means the work is still going on.

    What to bring to the surgery waiting room

    Why a small puzzle helps some people wait

    Waiting is hard partly because it has no edges. A short puzzle has edges: a start tile, a last tile, a moment when it is done. That is the reason we suggest it, and it is a modest one. A puzzle will not calm everybody, and you do not owe anyone calm.

    Sumthread fits this situation for practical reasons. It plays fully offline, so hospital Wi-Fi does not matter. It has no ads, so nothing loud or bright appears. It saves every step automatically, so you can close it the second you are called. One rule covers every board: draw a single path through every tile, up, down, left or right, hitting the target sums in order.

    One design decision we are glad about here: boards show elapsed time, but there is no countdown, and leaving a thread for an hour costs you nothing.

    Ways to pass the time, compared

    News and social feedsEndless, often upsetting, easy to keep refreshing.
    Waiting-room TVFree and passive; you do not pick the channel.
    A bookCalm, but hard to focus on long chapters when worried.
    A short walkGood for the body; tell the desk and keep your phone on.
    A short offline puzzleHas an end, works without Wi-Fi, pauses instantly. Sumthread is ours.

    Questions families ask in the waiting room

    What should I do while someone is in surgery?

    First make sure the hospital knows how to reach you and who the main contact is. Then look after your body (water, food, a short walk) and give your mind one small, finishable task at a time: a call, a page of a book, a short puzzle.

    How will I get updates during surgery?

    It depends on the hospital, so ask at the desk. At Memorial Sloan Kettering, for example, a nurse liaison calls a family member's cellphone with updates (MSK family guide, updated July 2026).

    Can I leave the waiting room during surgery?

    Often yes for short periods, as long as the staff can reach you by phone. Tell the desk before you go and keep your phone charged and the ringer on.

    Why is the surgery taking longer than they said?

    Times are estimates. Delays happen for many reasons, including before the operation starts. Hospitals such as MSK say they try to tell families when a delay happens. If you are worried, ask the desk or liaison for an update.

    What should I bring to a surgery waiting room?

    A phone charger, a water bottle, a snack you can eat in the cafeteria, a list of family phone numbers, a sweater, and one or two things to do that work without Wi-Fi.

    Is it okay to play games while a loved one is in surgery?

    Yes. Keeping your hands and mind busy for a few minutes is a normal way to cope with waiting. Choose something quiet that you can stop the moment your name is called.
