Local anesthesia involves injections which makes the skin numb (a specific area). In this a patient does not sleep but stays conscious and free from pain. There are few things that should be kept in mind before going for a surgery. First of all you should never hide anything from your doctor. If you are taking any medicine with or without prescription then do tell your surgeon or doctor about it. Even if you are taking any herb then also tell your doctor about it. You have to understand the seriousness of the surgery. There is no need to hide anything. Telling things will help you. Show all the reports whether the results are positive or negative. If you ever had an operation before then do tell or show papers of it to your doctors, it will help a lot. This will make the doctor aware of many things like, which anaesthetic medicine suits you. It is better if you know about the anesthesia procedure before. In most of the clinics and hospitals, consent papers are given to the patients to sign before giving any medicine related to the surgery. If you will know the procedure it will help you to decrease the anxiety and tension.
Anesthesia is given by anaesthetics. They will tell you which type of anesthesia will suit you. They will tell you about the risk of the anesthesia. Anaesthetist is responsible for giving you anaesthetic and for your wellbeing and also for your safety throughout your operation.
Few things that you have to do are, if you smoke then stop this habit long before it will help you in reducing the risk of breathing and also makes anaesthetic safer. If you are overweight, then losing weight also helps. If you have problem of loose teeth or crowns, treatment from your dentist may reduce the risk of damage to teeth if the anaesthetist needs to put a tube in the throat to help you breathe. If you have problems like diabetes, asthma or bronchitis, heart problems or hypertension you should ask your GP if you need a check-up.
The anaesthetist in the operation in the operation theatre will ask you to be still when the injection is given. You may feel a warm tingling feeling as the anaesthetic begins to take effect. The doctors will start surgery after they are sure that the area is numb. There will be a screen shield the operating site so that you will not see the operation until unless you want to because you are not having sedation, you will be alert and aware of your surroundings. Your anaesthetist will always be near you and you can speak to him or her whenever you want to.
