You have decided to undergo a surgery, so now you have to keep few things in your mind. If you have habit of smoking then you will be asked to stop it several days before the surgery as it increases your risk of getting a wound or an infection slows the speed of your recovery. After understanding the risk and benefits of your surgery you will be asked to sign a consent form by the hospital or clinic. After signing the consent the process or medication will start for surgery. You do not need to make some special preparations for local anaesthesia. Doctor will tell you what you have to eat or drink. Inhaled sedation makes you feel sick, so you may be asked to eat only light meals. Sometimes it is injected or swallowed.
Patients who think that they do not want to stay awake at the time of surgery or procedure may not be good person opted for local anaesthesia. In other types of anaesthesia there are medicines that relieve a patient from being tensed and anxious and also make the patient relax during the procedure. Any patient who had some kind of reaction to a local anaesthetic medicine in the past should talk to the doctor before using any type of local anaesthetic agent. Patient should tell the allergies related to foods, dyes, some preservatives, or even any herb that you are taking without prescription. Older people are quite sensitive and react easily to local anaesthetics, especially lidocaine. All the packaged directions should be followed so that the recommended dosage may not exceed. Until the anaesthetic wears off, the patient should be very careful. He should not knock the numbed area. If the anaesthesia was given through the mouth, person should not eat or chew gums until feeling returns. Person should talk to his doctor or anaesthetist if there is some kind of discomfort that continues for more than normal days, then the treated area becomes infected. If some new sign appear like skin rash, stinging, burning, or swelling appear.
In many cases, the patients can go back home soon after the local anaesthetic, but in a few cases a patient is kept under observation. The observation degree depends on the area where the anaesthesia is given, how much it is given and what is the condition of the patient. The patient who has undergone throat anaesthetic is not permitted to drink water or any other liquid till the gag reflex returns. A person who is given a large dose of local anaesthesia recovers in a post-anaesthesia care unit before he is discharged. Patients recover fast. It is safer than general anaesthesia as person is awake.
