Anaesthesiology is the medical specialty that deals with the administration of anaesthesia, which is the use of medications to block the sensation of pain and induce a state of unconsciousness or partial unconsciousness. Anaesthesiologists are physicians who are specially trained to provide anesthesia and manage the patient’s vital functions during surgery, as well as in other medical procedures. Anaesthesiologists are responsible for evaluating the patient’s medical history and current health status to determine the most appropriate anaesthesia technique for the procedure, monitor the patient’s vital signs throughout the procedure, adjust the anaesthesia as needed, and manage any complications that may arise during or after the procedure.
