Anaesthetics are drugs used to temporarily block sensations of pain and other sensations during surgical and other medical procedures. They are typically administered by an anaesthesiologist or a nurse anaesthetist.

There are several types of anaesthetics, including general anaesthetics, which cause unconsciousness, and regional anaesthetics, which numb specific areas of the body. Local anaesthetics, such as lidocaine, are used to numb a small area for a short time.

Anaesthetics work by blocking the transmission of nerve impulses that carry pain and other sensations from the site of injury or surgery to the brain. The choice of anaesthetic depends on the type of procedure, the patient’s medical history, and other factors, such as the patient’s age and any allergies they may have.

Anaesthetics are generally considered safe, but as with any medical intervention, there are risks and side effects associated with their use. These may include nausea, vomiting, headache, sore throat, and in rare cases, more serious complications such as allergic reactions and breathing difficulties. Before undergoing a procedure requiring anaesthesia, it is important to discuss any concerns or questions with the anaesthesiologist or the surgeon.
