First, the characteristics of on-site first aid
(1) Sudden on-site first aid often refers to the emergence of wounded or sick people in sudden catastrophic events, sometimes in small numbers, sometimes in batches, sometimes scattered, and sometimes concentrated. Most of the common patients are dying. Not only people at the scene need to participate in first aid, but also people outside the call center need more people to participate in first aid.
(2) Urgency After sudden disasters and accidents, the situation of the wounded is much more complicated. Many people have more than two musical instruments damaged at the same time, and many people are dying. The injured and their families are in a very urgent mood for help. Cardiac arrest for 6 minutes, incontinence, coma, irreversible damage to brain cells. Start cardiopulmonary resuscitation within 4 minutes, which may save 50%. 10% of the people who began to recover in 0/0 minutes could not survive. Therefore, time is life, and every minute counts. People with cardiac arrest and respiratory arrest should be rescued from the edge of the cliff by resuscitation technology, and those with severe bleeding and fracture should be rescued by hemostasis and fixation. Otherwise, there will be a serious mistake of "losing a mile, losing a thousand miles".
(3) Difficulty refers to the variety of the wounded and sick in the disaster and the serious injuries. A person may involve multiple systems and instruments at the same time, and needs rich medical knowledge and excellent technology to complete the first aid task. In fact, there are often cases where there are many patients, urgent requirements, high requirements and little knowledge. Some disasters, although there are fewer patients, are often in a sudden state of emergency. Even there are no people around the patients, let alone professional health personnel, and they can only rely on passers-by with basic life support technology to provide help and first aid. This situation is a difficult problem for people who have studied medicine and those who have been trained or untrained.
(4) Flexibility On-site first aid is often carried out under the condition of lack of medical care and medicine, and there are often no complete rescue equipment, medicines and rotating tools. Therefore, we should flexibly look for substitutes around the wounded and sick, repair the old and make use of the waste, and obtain washing disinfectants, bandages, splints, stretchers and so on. Take local materials; Otherwise, the chance of rescue will be lost, which will cause greater disasters and irreparable consequences to the wounded and sick.
(5) Key medical first aid includes out-of-hospital first aid, which objectively requires medical technical training, first aid medical equipment and equipment, especially comprehensive first aid professional equipment: hospital first aid should be specialized, mass first aid should be popularized, community first aid organizations should be networked, and first aid command system should be scientific. These are the key problems to complete first aid.
Second, the principle of on-site first aid
The general task of on-site first aid is to take timely and effective first aid measures and techniques to minimize the pain of the wounded and sick, reduce the disability rate and mortality rate, and lay a good foundation for hospital rescue. Priority is given to the wounded and sick who can survive the first aid at the scene. This is the general principle. In order to better accomplish this glorious and arduous task, we must also follow the following six principles. .
(1) The principle of resuscitation before fixation refers to the principle of resuscitating the heart, lungs and brain through mouth-to-mouth resuscitation and chest compressions in the case of cardiac arrest and fracture, and then fixing the fracture.
(2) The principle of stopping bleeding first and then bandaging refers to the principle that in case of massive bleeding and wound, acupressure, tourniquet or medicine should be used immediately to stop bleeding, and then the wound should be disinfected and bandaging.
(3) The principle of emphasizing first and then neglecting, refers to the wounded and sick who emphasize first and then neglect.
(4) The principle of saving the latter first In the past, most of the wounded and sick were sent first and then saved, which often delayed the rescue opportunity and led to the death of people who didn't deserve to die. It's time to reverse, save first and then send. On the way to the hospital, don't stop the rescue measures, continue to observe the changes of the injury, avoid bumping, pay attention to keep warm and reach the destination safely.
(5) The principle of paying equal attention to first aid and calling for help. When encountering a large number of wounded and sick people, many people can quickly win first-aid foreign aid in the current situation.
(VI) The principle of consistency between treatment and medical care In the past, when dealing with critically ill patients, treatment was separated from medical care and guardianship in thought and action. The transportation department is responsible for handling, and the health department is responsible for medical treatment on the way. It seems that it is only the responsibility of rescue.
Many times, the coordination is not good, and we have to continue to rescue on the way, but there is no guarantee. In addition, the vehicle was severely bumped, resulting in excessive pain and death of the wounded and patients. This situation is not uncommon at home and abroad. Medical rescue should be carried out under the conditions of consistent task requirements, coordinated pace and consistent task completion. When transporting critically ill patients, it can alleviate the pain, reduce the death and reach the destination safely.
In the past, the first aid was the method of "lifting your feet and running", which has been basically replaced by the idea of "waiting for the injury to stabilize the injury" in the international scope. This stable policy shows that it can effectively reduce the mortality and disability rate of first aid in wartime and peacetime. When "wait for a while, stabilize the injury", it is not that the wounded and sick are left unattended, but that the emergency personnel are nervously doing what they should do, opening the airway, CPR, controlling bleeding, braking fractures and carrying less, so untrained people should pay more attention.
At present, advanced countries have greatly strengthened the work of first aid and out-of-hospital transport. For example, in the United States, it only takes about 37 minutes from receiving the distress signal to being taken to the hospital, which greatly reduces the mortality rate and fully shows that time is life.
Three. First aid time standard
According to a large number of first-aid practices, the earlier the first-aid person approaches the wounded and sick, the shorter the first-aid time after injury and the higher the survival rate of the wounded and sick.
The best first aid period: within 0/2 hours after injury.
Better first aid period: within 24 hours after injury.
Delayed first aid period: 24 hours after injury.
