General anaesthesia is a medicine that puts the patient in a deep sleep so that he cannot feel any pain during the surgery. When a person receives this medicine he becomes unaware of what is happening around him. Anaesthesia is given by certified anaesthetist. It is done in two ways. Anaesthetist will either give the medicine in the vein of the patient or he will be asked to inhale some special gases through the mask. Once the person sleeps then the doctors may insert a tube into the trachea to help the patient to breathe and also protect his lungs. Kids may need this type of anaesthesia for a medical or dental procedure to handle any kind of pain or anxiety they may feel.
General anaesthesia is usually safe for healthy people but people with lung, heart, or some kidney problems or people who abuse alcohol or medications, and people who have some allergy or they have some family history of being allergic to some kind of medicine may have a higher risk of having problems with general anaesthesia.
Never hide anything from your doctor. Show your previous reports or reports of your any operation done before. Previous operation report will help the doctor in knowing about which anaesthetic medicines suits you and which does not suits you. Tell if you could be pregnant. Tell your doctor about your medicines or even herbs you bought for any prescription. A day before a doctor or anaesthetist will call you and will take a complete medical history. Then he will tell you about the type or amount of anaesthesia you need. He will ask about the allergies and about your general health. You may be asked to stop the intake of aspirin several days before of the surgery. Other medicines that you may have to stop are ibuprofen, warfarin, and any other drug that make it hard for your blood to clot. Doctor can also ask you to stop some other medicines because some medicines can cause reaction to the anaesthetic medicine that you will get at the time of surgery.
After the procedure you will wake up tired and groggy in the operation theatre. You can also have some other symptoms like having a dry mouth, sick to your stomach, sore throat, or may feel cold or even restless until the anaesthesia wears off. Doctors and nurses will monitor you. It can take few hours to wear off its effects. Some people have nausea and vomiting, this problem can be treated with other medicines. . If patient feels numbness or reduced sensation longer then the time period expected then he should contact to the anaesthetist or doctor. It is best to follow the instructions of the doctors.
