Emergency Medical Service Center, Royal Angkor Hospital is open 24 hours. We are always with you. Our critical care specialists, nurses and advanced-medical technology will ensure that our critically ill patients will be treated in a timely manner with the highest standard of care. The Royal Emergency Services (RES), which provide an ambulance and a medical emergency team, picks up emergency patients outside the hospital. It is well equipped by the same standards as the Bangkok Emergency Medical Services. After being picked up by an RES ambulance, the patient will be treated in the emergency room, and then will be admitted to either the Intensive Care Unit (ICU), general ward, or to the operating room. If the patient needs further treatment abroad, the Air Evacuation Emergency Medical team can escort the patient to Bangkok or any country via charter or commercial flights.
