Expert reviewer, Dr Ahmed Almaki, Consultant Anaesthetist General anaesthesia is when you have medicines to make you temporarily unconscious during an operation. You don't feel pain or other sensations while the effect lasts. About general anaesthesiaThe word ‘anaesthesia’ means 'loss of sensation'. Having a general anaesthetic puts you into a controlled state of unconsciousness. A general anaesthetic is usually several medicines used together to:
You may also have medicines that relax your muscles. You’re likely to need these if you’re having an operation on your abdomen (tummy) or chest. Having a general anaesthetic means you’ll be unconscious all the way through your operation. Your anaesthetist will stay with you throughout your procedure. When your operation is finished, they’ll stop the anaesthetic drugs. You’ll wake up and you won’t remember what happened. Before your procedure, you’ll meet your anaesthetist or specialist preoperative nurse to discuss your care. It might be different from what we've described here because it will be designed to meet your individual needs. Preparing for general anaesthesiaYour surgeon and anaesthetist will explain how to prepare for your operation and the general anaesthetic. That includes talking about the potential risks. You might find it helpful to prepare some questions to ask about the procedure or the anaesthetic. It will help your recovery if you’re as fit and as well as possible beforehand. These are the main things that can help you to do that.
If you’re having a major operation such as heart or brain surgery, you’ll usually be asked to go to a pre-assessment clinic a few weeks before. At the clinic you’ll probably see your anaesthetist and have some tests and checks done. These are to see what your general health is like. If you’re taking any regular medicines including over-the-counter or herbal medicines, tell the staff at the clinic. On the day of your operationHaving a general anaesthetic can sometimes make you sick. If that happens while you’re unconscious, it can be dangerous. So, your stomach needs to be empty before your operation. You’ll be given information about when to stop eating and drinking. The advice is usually not to eat anything in the six hours before surgery. You should be able to drink clear fluids such as water or black tea or coffee up to two hours before your operation. If you’ve been asked to take your usual medication before your operation, you can take it with a small sip of water. Follow your anaesthetist or surgeon's advice and if you have any questions, just ask. At the hospitalYour nurse or surgeon will talk to you about what will happen, including any pain you might have. If you’re unsure about anything, just ask. No question is too small. Being fully informed will help you feel more at ease and will allow you to give your consent for the procedure to go ahead. You may be asked to do this by signing a consent form. There are some important things to do on the day of your operation.
Pre-medicationPre-medication is one or more medicines given to you just before your operation. Not everyone has them, but they’re normally given one or two hours before a procedure. Pre-medication can include:
If you’re very anxious about the operation, you may also be given medicines to help you relax. What happens during general anaesthesia?You’ll probably have your anaesthetic in a room next to the operating theatre. When you get there, your anaesthetist or operating assistant will go through some safety checks with you. These include checking your name, asking if you have any allergies and what operation you’re having. You’ll be connected to equipment that monitors your heart rate, blood pressure and oxygen levels during the operation. You’ll have a small plastic tube called a cannula put into the back of your hand or arm. There are two main ways to have anaesthetic medicines:
You might have one or both of these. Whichever way you have the anaesthetic, it will start to work within a minute or two. You’ll then ‘fall asleep’ and won’t wake up until after your procedure. When you’re unconscious, your anaesthetist might put a tube in your mouth to help you breathe. You‘ll be given more anaesthetic medicines during the operation to make sure you stay unconscious. During the operation, your anaesthetist and nurses will make sure you’re kept warm enough. They’ll also check the position you’re lying in to prevent any damage to your joints, skin or nerves. Your anaesthetist may also give you:
Your anaesthetist will be with you throughout the operation, watching the monitors and making any changes needed. At the end of your procedure, they’ll start the process of waking you up by stopping the anaesthetic medicines. What to expect after general anaesthesiaWhen you wake up, you’ll be in a recovery room next to the operating theatre. A specialist nurse will be there to look after you. They’ll check on you regularly. If you feel sick or have pain, they will give you medicines to ease your symptoms. You may have oxygen to breathe through a mask and fluids through the cannula in your arm. You’ll also be attached to heart, blood pressure and oxygen monitors for a while after your procedure. You’ll be taken back to your ward when your anaesthetist is happy that you’re recovering well. Tell your nurse if you’re in pain. Getting your pain under control will help you to move more which can help with your recovery. Other care you have will depend on the type of procedure you’ve had and your personal needs. When your nurse thinks that you’re ready, you can have something to eat or drink. The effects of the anaesthetic can last for 24 hours, or longer if you have had a major operation. When you can go home will depend on the operation you’ve had and how well you’re recovering. If you’ve had a day-case procedure, you’ll usually be able to go home when you’ve recovered and feel ready on the same day. Make sure someone can take you home and stay with you for a day or so while the anaesthetic wears off. Recovering from general anaesthesiaHaving a general anaesthetic can really take it out of you. You might find that you're not so coordinated or that it's difficult to think clearly. This should pass within 24 hours. In the meantime, don't drive, drink alcohol, operate machinery or sign anything important. You may feel tired or even exhausted after a general anaesthetic, and this might last for a few days. If it lasts longer, it is more likely to be due to other things, such as lack of sleep, anxiety or not being able to eat or drink properly. The healing process after a big operation can leave you feeling very tired. Side-effects of general anaesthesiaSide-effects are unwanted but mostly temporary effects of the anaesthetic. They include:
If you’re worried about any side-effects or they don't get better, contact your hospital. Complications of general anaesthesiaGeneral anaesthetics have some risks. These are different for everyone, so ask your anaesthetist how they apply to you. Complications are problems that can occur during or after a procedure. General anaesthesia complications are rare but can be serious. They may be more likely if:
These are some of the main complications of general anaesthesia.
Some people worry about being ‘awake’ during an anaesthetic or being aware of what is going on during the operation. This does happen, but it’s very rare. It happens in about one in every 20,000 anaesthetics. It might mean being aware of talking or having something put in your mouth. A few people are aware of being unable to move or feel pain. It usually lasts for a few minutes, but it can be very distressing. Always tell your anaesthetist after your operation if this has happened to you. What are the alternatives to general anaesthesia?General anaesthesia isn’t right for everyone. You may have a regional or local anaesthetic instead.
You’re awake during procedures done using regional or local anaesthesia. Some people choose to have a sedative as well to help them relax. How much you remember about the procedure afterwards varies from person to person. Your anaesthetist will talk to you about the different options and which might be best for you.

It usually lasts for approximately 4 - 6 hours. During this period take care not to injure the area which has been numbed as you may not feel any damage.
How do you flush anesthesia out of your system?Sweating, such as through a sauna, is a great way to excrete toxins. For the two weeks after surgery, take a sauna a few times if permitted by your doctor. Make sure to wash the toxins off of your skin after the sauna by showering and washing your body with a castile soap.
