Anaesthetics is the study of pain relief, use of anaesthesia and resuscitation. The anaesthetist is especially important when it comes to surgery.
Before a surgical intervention he goes over all the important points with the patient, e.g. what medicines he regularly takes, or how the patient reacted to any earlier anaesthesia. He then chooses the right medicines for the upcoming operation and administers them to the patient. During the operation he monitors the patient's heart / lung activity and circulation using a variety of equipment. After the intervention he continues to monitor the patient's health and intervenes if any problems arise.
