The wound dressing should know whether there is internal injury or not. At the scene of trauma first aid, we should not only pay attention to the wound that can be seen on the surface and ignore other internal damage.If there is fracture or not, the dressing method is different. If there is fracture, the correct fixation of fracture site should be considered; If the wound of the same body is combined with internal organ injury, such as liver rupture, intraperitoneal hemorrhage, hemothorax, etc., priority should be given to the treatment of visceral injury, instead of delaying the dressing of surface wound; for the same head wound, if combined with craniocerebral injury, it is not simply bandaging to stop bleeding, but also needs to strengthen monitoring. For patients with head impact. Even if the consciousness is good, it needs to be observed for 24 hours. If head distension, headache aggravation, even nausea and vomiting, it indicates that there is intracranial injury, and emergency treatment is needed.Therefore, before or at the same time, it is necessary to know whether there are other parts of the injury before or at the same time, especially pay attention to whether there are hidden visceral injuries.Dressing of wounds communicating with the body cavityFor the open wound connected with the body cavity, the site generally only needs to cover the wound, and then send it to the hospital as soon as possible or contact the medical personnel for treatment as soon as possible. For example, the abdominal wound communicated with the abdominal cavity can be covered with clean gauze, towel, quilt, etc. If there is intestinal tube or omentum protruding from the wound, do not try to put it back into the abdominal cavity, in order to avoid aggravating abdominal cavity pollution. For the expanded intestinal tube or omentum, it should be completely covered with a clean bowl, or wrapped around with clean gauze, so as to prevent extrusion of the expanded intestinal tube or omentum.For example, the chest wound connected with the chest cavity can cause open pneumothorax. Among them, "traffic type pneumothorax" and "high pressure (tension) pneumothorax" have serious symptoms, which can even lead to coma and death.The former should close the wound with sterile gauze or other clean dressings as soon as possible, bandage and fix it to prevent abnormal breathing, so as to reduce the symptoms and continuous injury. For the "high pressure (tension) pneumothorax", due to the formation of a unidirectional valve at the rupture, when the person inhales, the opening opens, and the gas continuously enters the pleural cavity; when exhaling, the gap is closed, so that the gas can not be discharged. The increasing pressure in the chest cavity increases the pressure on the lung, which leads to progressive dyspnea. At this time, emergency exhaust treatment should be performed, and large injection needle can be used to stab the pleura in the second intercostal space of the midline of clavicle.In addition, if a large amount of reddish flows out of nostrils and ears in patients with head trauma, skull base fracture should be considered, and the wound is connected with the cranial cavity. Do not try to compress and pack the nostrils and ears of the injured person at the scene, so as to avoid intracranial infection. If the fracture pierces the scalp or has brain tissue bulge, it can be treated according to the principle of abdominal viscera bulging.Wound dressing with bleeding as the main symptomIn the case of bleeding, the implementation of wound dressing must be based on hemostasis. If not given hemostasis in time, it can cause serious bleeding, shock, and even life-threatening.Sometimes, the dressing itself is a measure of hemostasis. For example, tissue injury caused by capillary bleeding, bleeding, blood like water droplets from the wound, a little pressure can stop bleeding, sometimes can also automatically coagulation hemostasis. This kind of bleeding, often only need to stick on the wound hemostatic paste, or cover the wound with disinfection gauze, and then slightly pressure bandage, can complete the double task of hemostasis and dressing. But for the "arterial bleeding" caused by arterial vascular injury and "venous hemorrhage" caused by venous vascular injury, simple compression bandaging wound can not achieve the purpose of hemostasis.When the artery is bleeding, the bleeding is pulsating and jetting, and the blood color is bright red, which can cause massive blood loss in a short period of time, causing life danger; when the vein bleeding, the bleeding slowly and continuously flows out, and the blood color is purplish red. Emergency measures such as "finger pressure" and "tourniquet" can be used to stop bleeding temporarily, and then sent to the hospital or asked for rescue personnel.Finger pressure hemostasis is in the upper part of the wound, that is, near the heart end, to find the beating blood vessels, tightly press with the fingers. It should be noted that this method can only be used to control blood flow for a short time, and "tourniquet" hemostasis should be used immediately.Tourniquet is an elastic rubber band (dressing should be padded between the belt and the skin). It can also be replaced by cloth belt, towel and tie with a width of more than 3 cm. Bind the upper arm or the upper and middle 1 / 3 junction of the upper arm or thigh (Note: the upper arm should not be too low, otherwise it is easy to damage the nerve). The degree of tightness of the binding should be based on no blood outflow from the wound. In addition, be sure to mark the time of the tourniquet on the prominent part, and loosen the tourniquet every hour for a few minutes. Bind again.Improper dressing can lead to serious consequencesWhen someone bandaged the "elbow joint injury" of the child, they fixed "the forearm and the upper arm in a straight line" for a long time. As a result, the child's "elbow joint lost its due bending function" and was disabled. The reason is that Liu readers do not know that the joint should be fixed in the "functional position" when bandaging. Even if the joint is unable to move after injury, it can retain some physiological functions of the original joint to the maximum extent.For the upper limb, the most important thing is to ensure the function of the hand; for the lower limb, it is mainly to ensure the function of holding and walking. Therefore, the functional position of elbow joint is nearly 90 degrees flexion, the functional position of knee joint is slightly flexion 10 degrees, and the functional position of finger joints of hand is flexion 45 degreesKey FeaturesThe wound dressing should know whether there is internal injury or not.
