Emergency Medicine

Emergency medicine is the specialty of the first hours of an illness or injury. Emergency physicians and nurses are trained to see patients they have never met, with problems that range from a sprained ankle to a heart attack, and to make safe decisions quickly. The core questions are always the same: is this life-threatening, what is the likely cause, what treatment is needed now and where should the patient go next. The emergency department is open around the clock and accepts patients without an appointment, which is why it works on a triage system rather than a queue. Emergency medicine does not replace the specialist who will look after a condition in the long term. Its role is to recognise danger, stabilise the patient, relieve pain and symptoms, and then either discharge safely with clear advice or hand care over to the right ward or specialist team.

Emergency departments see a very wide range of problems. Common ones include chest pain, shortness of breath, high fever, severe headache, abdominal pain, vomiting and diarrhoea with dehydration, kidney stone pain, allergic reactions, fainting and sudden weakness or confusion that may signal a stroke. Injuries make up a large share: falls, sprains and fractures, cuts that need stitches, burns and head injuries. For travellers, typical reasons for a visit include stomach and bowel infections, heat illness, injuries on holiday, flare-ups of a long-term condition when medicines run out or routines change, and symptoms that appear around a planned procedure, such as a fever, a swollen leg or chest discomfort. Within the specialty, adult emergency medicine, paediatric emergency care for children, resuscitation and trauma care for the most serious cases, and short-stay observation units each have their own teams and protocols.

Treatment starts with whatever is most urgent. For serious illness this means supporting breathing and circulation, giving oxygen, intravenous fluids and medicines, and treating causes such as a heart rhythm problem, a severe infection or a dangerous allergic reaction straight away. Pain relief is given early, because uncontrolled pain makes assessment harder. Many treatments are carried out in the department itself: cleaning and closing wounds, splinting or plastering a fracture, putting a dislocated joint back in place under short sedation, draining an abscess or giving nebulised medicines for an asthma attack. When the cause is not yet clear but the patient is stable, a period of observation lets the team repeat tests and watch how symptoms change. If a condition needs further treatment, the emergency team refers to the specialist on call, such as cardiology, general surgery or neurology, and arranges admission or a follow-up appointment.

Speed and focus define emergency diagnostics. On arrival, a triage nurse measures pulse, blood pressure, temperature, breathing rate and oxygen level and asks about the main complaint, which sets how quickly a doctor sees you. Blood tests can show infection, dehydration, bleeding, kidney or liver problems and markers of heart muscle damage, often within an hour or two. An electrocardiogram is recorded within minutes for chest pain. Bedside ultrasound helps the emergency doctor look quickly for fluid, bleeding or problems with the heart, and X-rays show fractures and chest conditions. CT scanning is available for head injury, suspected stroke, severe abdominal pain or a possible blood clot in the lungs. The emergency team chooses tests by the question they need to answer, so you may not receive every test you expect, and that is usually a sign of careful, focused care rather than an oversight.

If you become unwell during a stay abroad, keep a few things with you at all times: your passport, travel or health insurance details, a list of your medicines and allergies, and copies of reports from any planned treatment. Save the local emergency number and the contact details of your hospital coordinator in your phone. If you are abroad for planned treatment and develop a new problem, such as a fever, chest pain, breathlessness, a swollen painful leg or bleeding, contact your treating team straight away; they may ask you to come to the emergency department so the problem can be assessed before the procedure goes ahead or continues. Emergency teams commonly have access to interpreters or international patient services, although availability at night can vary. Ask for a written discharge summary in a language you read, and share it with your insurer and your doctor at home.
