Why an on-site anesthesiologist matters for surgery in Korea
An on-site anesthesiologist matters because a specialist doctor based at the clinic checks your health before sedation or general anesthesia, watches your breathing, heart and oxygen throughout the operation and looks after you in recovery. Before you book surgery in Korea, ask who gives your anesthesia and whether they stay until you are discharged from their care.
What does an anesthesiologist do before, during and after surgery?
An anesthesiologist is a doctor who specializes in anesthesia, the medicines that keep you calm, asleep and free of pain during an operation. Their work does not start when you fall asleep or end when you wake up. It covers three stages: before, during and after surgery.
Before surgery, the anesthesiologist reviews your health: your medical history, the medicines you take, any problems with anesthesia in the past and the results of your pre-op tests. From that they decide which type of anesthesia suits you and explain its risks. The NHS describes the same step: a specialist doctor reviews you beforehand and talks you through the options.
During surgery, they give the anesthetic, adjust the dose and watch you without a break. The standards of the American Society of Anesthesiologists (ASA) say that qualified anesthesia staff should be in the room for the whole of a general anesthetic or monitored anesthesia care (sedation given by an anesthesia professional), and that your oxygen, breathing, circulation and temperature should be checked continually. Your condition can change quickly under anesthesia, which is why someone has to be watching all the time.
After surgery, you wake up in a recovery room, where staff keep checking your breathing, pain and nausea until you are ready to leave. The ASA standards for this stage make an anesthesiologist responsible for supervising recovery care and a doctor responsible for deciding when you can be discharged from it.
Sedation or general anesthesia: why does it matter who watches you?
Clinics in Korea often call IV sedation “sleep anesthesia”. It is not general anesthesia. You breathe on your own, but you may sleep through the operation and remember little of it. General anesthesia goes further: you are fully unconscious, and you often need help with your airway, such as a breathing tube.
The ASA describes sedation and anesthesia as one continuous scale, not separate boxes. The levels in the table below are its definitions. A patient can slip from one level to a deeper one during a procedure, and bringing someone back from deeper sedation than planned takes a person skilled in managing the airway. That is why the question “who is watching me?” applies to sedation as much as to general anesthesia.
At Urban Plastic Surgery, our partner clinic, breast augmentation and an SMAS facelift are done under general anesthesia, and rhinoplasty under sedation or general anesthesia. Ask which one your own plan uses, because the answer shapes your fasting, your recovery and how long you stay at the clinic afterwards.
| Level | How you respond | Breathing and airway | Heart and circulation |
|---|---|---|---|
| Minimal sedation | Normally, when someone speaks to you | Not affected | Not affected |
| Moderate sedation (“conscious sedation”) | Purposefully, to a voice or a light touch | No help needed, breathing is adequate | Usually maintained |
| Deep sedation | Purposefully, but only to repeated or painful stimulation | Help with the airway may be needed, breathing may be inadequate | Usually maintained |
| General anesthesia | You cannot be woken, even by pain | Help with the airway is often needed, breathing is often inadequate | May be impaired |
What is the difference between an on-site and a visiting anesthesiologist?
Clinics organize anesthesia in different ways. An on-site anesthesiologist works at the clinic and is in the building on operating days. A visiting anesthesiologist comes in for a booked list of operations and works at other places on other days. At some clinics the surgeon gives sedation while operating, with no anesthesiologist involved.
On-site and visiting anesthesiologists can both follow the same safety standards. The ASA statement on anesthesia in office-based clinics says the anesthesiologist should be physically present during the operation and immediately available until you have been discharged from anesthesia care, and that the clinic needs oxygen, suction, resuscitation equipment, emergency drugs and backup power. If a clinic uses anesthetic drugs that can trigger malignant hyperthermia, a rare but serious reaction to anesthesia, it should keep the medicines, equipment and written plans to treat it at hand.
What the arrangement changes is who is there and when. With an on-site anesthesiologist, the doctor who reviews your tests can be the same doctor who puts you to sleep, and a specialist is still in the building while you recover. With a visiting anesthesiologist, ask whether they stay until you leave the recovery room and who takes over if a problem appears after they go. If the surgeon gives your sedation, ask who watches your breathing and oxygen while the surgeon’s hands are busy.
How does our partner clinic handle anesthesia?
Urban Plastic Surgery, our partner clinic, has 4 doctors, and 2 of them are board-certified anesthesiologists: Dr. Moon Ji-hyun and Dr. Park Jeong-bok. Both are members of the Korean Society of Anesthesiologists. The clinic states that an anesthesiologist is always on site, from the pre-op check until after surgery.
Its English breast surgery pages describe on-site supervision by an anesthesiology and pain medicine specialist, who monitors your anesthesia during the operation. The clinic also states that operations are watched in real time on a central monitoring system, that pre-op health checks are done at the clinic with a clinical laboratory technologist on site, and that it keeps dantrolene, the drug used to treat malignant hyperthermia.
Ask for these points in writing for your own surgery date, as you would at any clinic: the name of the anesthesiologist, the type of anesthesia and who looks after you in recovery. For the rest of the safety checks, including the surgeon, CCTV in the operating room and the emergency transfer plan, see our guide on how to choose a plastic surgery clinic in Korea.
How should you prepare for sedation or general anesthesia?
Much of your preparation is sharing the right information. The anesthesiologist can only plan around what they know, so tell them about the points below at your consultation or pre-op check, and bring your medicine boxes or photos of the labels.
Follow the clinic’s fasting rule exactly. At our partner clinic, that means nothing by mouth for at least 6 hours before surgery: no food, water, gum, sweets or coffee. For general anesthesia, stop eating and drinking at midnight the night before. Fasting keeps your stomach empty while your reflexes are switched off. If you ate or drank by mistake, say so before surgery, even if it means a new time.
After general anesthesia, the NHS advises having a responsible adult with you for at least 24 hours, and not driving, drinking alcohol or signing legal documents for 24 to 48 hours, because memory and reflexes can be affected for a day or two. If you are traveling alone, plan who will collect you and stay with you at the hotel on the first night. As after any operation, if you become breathless or have chest pain, get emergency care first, then tell the clinic. Our surgery trip timeline shows how these first days fit into your stay.
- Every medicine you take, including blood thinners, supplements, herbal products and weight-loss injections
- Any problem with anesthesia in the past, yours or a close relative’s
- Heart, lung, liver or kidney conditions, diabetes, high blood pressure or asthma
- Snoring or sleep apnea, and whether you use a breathing machine at night
- Smoking, vaping and how much alcohol you drink
- Allergies to medicines, latex or tape
What should you ask about anesthesia at your consultation?
These questions take a few minutes and give you answers you can compare between clinics. Ask them before you pay a deposit, and keep the answers with your quote. Our surgery quote checklist shows where anesthesia should appear on the written quote.
If you would like help asking them, start a free consultation. A patient coordinator answers first, then the surgeon at the partner clinic that fits your case reviews your photos and consults in depth. You can add the questions above to your first message, and they are passed on with your photos. Your coordinator is not a doctor and does not choose your anesthesia: the surgeon and the anesthesiologist decide that together. Our consultation is free for you, and you pay only the clinic’s own price for treatment.

More questions
Is “sleep anesthesia” in Korea the same as general anesthesia?
No. In Korea, “sleep anesthesia” usually means IV sedation: you keep breathing by yourself, while general anesthesia makes you fully unconscious and often needs help with your airway. Sedation can become deeper than planned, so ask who watches you in either case.
Is sedation safer than general anesthesia?
Not automatically. Sedation avoids a breathing tube and is often used for shorter operations, but it still affects breathing and can drift deeper than intended. General anesthesia suits longer or larger operations. The safer choice depends on your health and the surgery, and the anesthesiologist explains the risks for you.
Will I meet the anesthesiologist before my surgery?
You should meet them before you go to sleep, so they can review your health, tests and medicines with you. Ask when that happens: at the pre-op check or on the morning of surgery. If you have a condition that affects anesthesia, ask whether they can review it earlier, ideally before you travel.
Can a plastic surgeon give the sedation as well as operate?
Yes, at some clinics the surgeon gives the sedation and operates at the same time, with no anesthesiologist present. If that is your plan, ask who watches your breathing and oxygen throughout and who would manage your airway if the sedation became deeper than planned.
