Why you cannot drive yourself home
No, and the rule is not negotiable at any depth of sedation beyond local anaesthetic alone. An adult has to take you home and stay with you, and an appointment where that person has not been arranged does not proceed. Ride-share does not satisfy the requirement, because a driver who does not know you is not an escort — they cannot notice that you are unwell, they will not come inside, and they are not staying.
The reason is a mismatch between two things that recover at different speeds. Alertness comes back relatively quickly. Judgement, reaction time, coordination and the ability to form new memories take considerably longer, and they recover without announcing themselves. A person can hold a coherent conversation, walk unaided, and appear entirely normal while still being measurably impaired on exactly the functions driving depends on. Feeling fine is a poor instrument for detecting this, because the faculty doing the assessing is the impaired one.
The medicines used for IV moderate sedation are generally short-acting, which is precisely why this trips people up. The drug that made the procedure tolerable has largely worn off within an hour or two, so the subjective experience is of having returned to normal well before the objective measures agree. The conventional instruction is to treat the remainder of the calendar day as a period of impairment regardless of how you feel.
What your escort is actually agreeing to
The word escort undersells the commitment, and it is worth spelling out to whoever you ask, because a friend who thought they were providing a lift and discovers they are providing an afternoon is a friend with somewhere else to be.
- Be present in the building for the appointment rather than leaving and returning, because discharge timing moves and cannot be predicted to the quarter hour
- Receive the post-operative instructions in person, and take them away in writing
- Take you home and get you inside
- Stay with you for the first several hours, not drop you at the door
- Be someone who can telephone for help and describe what they are seeing
- Be an adult who is not themselves being sedated that day
That last point matters more often than it should. Two people from the same household booking sedation appointments on the same day leaves nobody in a fit state to supervise anyone, and it is generally discovered at the point of discharge rather than at the point of booking.
If you live alone and cannot arrange someone to stay, say so when booking rather than on the day. There are ways to work around it — a different anaesthetic plan, a different time, a staged approach — but all of them require knowing in advance. An appointment cancelled at the chair because the escort arrangement does not hold is the outcome nobody wanted, and it is entirely avoidable with one sentence at the right moment.
Where the patient is under eighteen, the escort is not a matter of arrangement at all: a parent or legal guardian must attend, sign, and remain in the building for the whole appointment.
How the discharge decision gets made
Discharge after sedation is decided against criteria rather than against the clock. There is no fixed interval that makes a patient safe to leave, and a team working to a schedule rather than to observations is working the wrong way round. What is being assessed is whether you have returned to a state where the escort can reasonably take over.
| What is assessed | What is being looked for | Why it matters |
|---|---|---|
| Consciousness | Awake, oriented, responding appropriately | The baseline everything else rests on |
| Airway and breathing | Clear airway, comfortable regular breathing | The function sedation most affects |
| Circulation | Blood pressure and pulse near your own baseline | Compared to your own readings, not a standard |
| Movement | Able to stand and walk with minimal help | Coordination lags behind alertness |
| Nausea and vomiting | Settled, and able to keep fluid down | A practical barrier to going home |
| Surgical site | Bleeding controlled, no expanding swelling | The reason for the appointment |
| Escort | Present, briefed, and staying | Care transfers to them at the door |
The journey itself is worth a moment's planning too. Sit in the back rather than the front where you can, keep a container within reach in case of nausea, and take the shorter route rather than the faster one if the faster one involves a highway. Patients not uncommonly feel worse in a moving car than they did in the recovery chair, and a journey that can be interrupted is preferable to one that cannot.
Expect the process to take longer than you have budgeted for, and expect the estimate you were given to be approximate. Patients metabolise these drugs at different rates, and the appointment before yours may have run long. Recovery is one of the parts of the day that should not be hurried, and a team willing to keep you an extra half hour is doing the right thing rather than falling behind.
Why you may not remember being told anything
Anterograde amnesia — reduced formation of new memories — is a normal and expected effect of the drugs commonly used for IV moderate sedation, and for many patients it is part of the point. What surprises people is how long it persists past the procedure and how convincing the illusion of remembering is. Patients routinely hold entire conversations at discharge, nod in the right places, ask sensible questions, and retain none of it.
The consequence is practical rather than alarming. Verbal instructions given to a patient who has just been sedated are, to a substantial degree, not being received. That is the reason the instructions go to the escort in person and go home in writing, and it is the reason the escort is asked to be in the building rather than in the car park.
It is also the reason not to make decisions that day. Signing anything, agreeing to anything financially, or having a conversation that matters is poorly timed when the record of it may not survive. The standard advice against signing legal documents on the day of sedation exists because of the memory effect at least as much as the judgement effect.
- Have the written instructions handed to the person taking you home, not folded into your own pocket
- Ask your escort to read them aloud once you are home, when you will retain more
- Photograph any prescription and any instruction sheet before you leave the building
- Write down the number to call and put it somewhere you will find it at two in the morning
- Do not rely on your own memory of what was said about the operation itself — ask again at the review
The rest of that day
The restrictions for the remainder of the day are about supervision and judgement rather than about the mouth, and they run alongside the ordinary post-operative instructions rather than replacing them. The general principle is simple: do not be the responsible adult for anything, including yourself.
| Do not | Why | Usually resumes |
|---|---|---|
| Drive or ride anything | Judgement and reaction time lag behind alertness | Next day, if you feel normal |
| Sign contracts or make decisions | Memory formation is affected for hours | Next day |
| Care for a child or dependent alone | Requires exactly the faculties that are impaired | Next day, with someone available |
| Drink alcohol | Adds to residual sedative effect | Ask — it also interacts with medication |
| Cook, or use anything sharp or hot | Coordination, and a numb mouth cannot detect heat | Later that day if someone is present |
| Climb ladders, swim, exercise | Balance and blood pressure | Next day at the earliest |
| Take medication not on your list | Interactions with what was given | Check first, always |
Eating and drinking follow the surgical instructions rather than the sedation ones. Start with fluids, move to soft cool food as nausea allows, and do not force it. Nausea after sedation is common and usually settles within a few hours; nausea that continues past that, or that prevents you keeping fluids down, is worth a telephone call.
Sleep is expected and is not something to resist, though your escort should be able to rouse you easily. Someone who cannot be woken normally, whose breathing seems laboured or unusually shallow, or whose colour has changed needs emergency help immediately rather than a call to the practice.
Planning it properly, a few days ahead
Almost every problem with the day after sedation traces back to something that was not arranged in advance. The escort was assumed rather than confirmed. Nobody thought about who collects the children. The fasting instruction was read the night before and misunderstood. The prescription could not be filled because the pharmacy had closed by the time discharge happened.
- Confirm the escort by name, and confirm they understand they are staying, not dropping off
- Arrange cover for children, dependants and pets for the whole day and the evening
- Take the day off work, and do not schedule anything for the evening
- Read the fasting instructions when you receive them and ask about anything ambiguous, particularly regular medication
- Ask in advance which medicines you should still take on the morning, because the answer differs by drug
- Find out where the prescription will be filled and whether that pharmacy will still be open
- Get soft food, cold drinks and an extra pillow into the house before the day
- Put your instructions, the practice number and your escort's number in one place
One further arrangement is worth making explicitly, because it is the one people find awkward to raise. Decide in advance who is allowed to be told what. An escort who is going to receive your post-operative instructions is going to hear something about your treatment, and if that person is a colleague or a neighbour rather than a partner, it is worth being clear beforehand about what you are comfortable with them knowing. Saying so at booking is easier than negotiating it in a recovery area.
The question about regular medication is the one most often left unasked. Some medicines should be taken as normal on the morning of sedation with a sip of water, and others should not, and the answer depends on the drug and on your own medical history rather than on a general rule. Ask specifically, name every medicine including anything bought without a prescription, and follow what you are told rather than what you read somewhere.
