In general anaesthesia, the entire body is affected and it renders the person unconscious. In this type of anaesthesia you will not feel any type of pain during the process of surgery. It causes amnesia and relaxes the muscles of overall body that makes it easy for doctors to do their work properly. This anaesthesia supresses many automatic functions like controlling breathing, heartbeat, movement of the digestive system, circulation of blood, throat reflexes like swallowing, coughing and also prevents foreign material from being inhaled into lungs.
First of all, the main thing is you should understand is the seriousness of operation. Never hide anything from your doctor. Show all the reports whether the result of report is positive or negative. If you ever had any operation before, then do tell or show papers of it. By this, doctors will know if you are allergic to some anaesthetic. They will come to know which anaesthesia will suit you.
It is better to know before about the anaesthesia procedure. It will help you in remaining calm and relaxed. If you will know the procedure it will help you to decrease your tension and anxiety. Generally, the surgeon’s office, clinic or hospital contacts the patient. They tell the patient about the procedure a day before only. They also tell the patient about what will happen who patient will arrive at the clinic or hospital, after the procedure and during the procedure. They will tell you about your diet and medicines. Some medicines can interact with the medicines used for anaesthesia.
Usually all the hospitals and clinics give consent to sign. They will discuss all the importance and seriousness of the procedure to the patient. It is signed before giving any medicine to make you ready for the operation. Mental relaxation techniques help to reduce the anxiety before surgery. Some medicines are given before anaesthesia. They are given by orally or by injections.
Anaesthesia is given by an anaesthetist. Some instruments are attached to check heart rate, breathing, oxygen level, blood pressure and other functions of the body. Then positioning of the body is done. There are three phases of anaesthesia.
First when you start receiving anaesthetic, it is called induction. General anaesthesia is generally induced with IV anaesthetics but inhalation anaesthetics can also be used.
Monitoring and maintenance is the second phase of the anaesthesia. They keep check on the vital organs of the body and then medicine is adjusted based on the response of the patient’s body during the procedure. They check patient’s heart rate, breathing, blood pressure and other body functions.
Emergence is the final phase of the anaesthesia. When the procedure is done the anaesthetist will stop giving medicine. If patient feels numbness or reduced sensation longer then the time period expected, then he should contact to the anaesthetist or doctor.
