May 12, 2008, the death of the nation. After the arrival of the disaster, how to control mortality, deter the occurrence of adverse cardiovascular events and kidney injury and thrombosis prevention and control, is a great challenge for the majority of health workers. 1, post-disaster stress, increased cardiovascular risk After the arrival of disasters, the more common trauma are fractures, open injuries, cranio-cerebral injuries, crush injuries, multiple injuries, etc.. And huge natural disasters will bring acute and chronic psychosomatic stress to people. Acute stress induces cardiovascular events mainly by activating the nervous system and enhancing the effects of cardiovascular risk factors. A Japanese study showed that cardiovascular mortality rates remained high for months after an earthquake. A U.S. study found a significant increase in deaths from coronary artery disease after a population experienced significant environmental stress. It is clear that a heavy disaster area increases many risk factors and makes it more likely that a cardiovascular event will occur. Therefore, during the whole rescue process, the possibility of cardiovascular events should be fully considered, and we should strive to reduce various risk factors as soon as possible to reduce mortality. 2, post-disaster attention to diabetes For diabetes, after the disaster, the eating pattern is disrupted, the diet structure is suddenly changed, the medication is interrupted, and the emotional stress all lead to blood sugar regulation disorder, so that diabetic patients fall into the dangerous situation of too high or too low blood sugar. For this reason, the American Diabetes Association recommends that doctors should not focus on the strict control of blood glucose, but should pay sufficient attention to the acute complications of diabetes in the event of a disaster. 3. Prevention of thromboembolism In the aftermath of an earthquake, trauma, fractures, surgery and prolonged unchanged braking positions significantly increase the incidence of pulmonary embolism and peripheral vascular embolism. Studies have shown that erythrocyte specific volume, fibrinogen, vascular pseudohemophilic factor, D-dimer and fibrinolytic and antifibrinolytic inhibitor levels are significantly higher in patients with hypertension during and after an earthquake. Therefore, the risk of thrombosis should be fully considered for early prevention and control. This aspect can be addressed by referring to the consensus on thromboembolism prevention. 4, kidney injury After the earthquake, the injured person’s muscles suffer from long-term severe compression and inflammation, necrosis, myoglobin and a large number of decomposition products and toxins into the blood circulation, and block the renal tubules, coupled with a large amount of sweating, blood loss, can not be timely replenishment of water, resulting in a decrease in blood volume, resulting in serious kidney injury. It is manifested as a significant increase in blood creatinine and urea nitrogen, as well as hyperphosphatemia, hyperkalemia and severe acidosis. In particular, hyperkalemia can lead to cardiac arrest or severe shock, which is the main cause of early death in patients with post-earthquake extrusion syndrome. Therefore, we are required to give large amounts of saline and appropriate amounts of sodium bicarbonate to the crushed casualties at the earthquake site while they should be excavated and rehydrated, while ensuring cardiopulmonary function, in the hope of keeping the casualties with urine. Be sure to monitor urine volume, blood biochemistry and electrocardiogram indicators, take the initiative to grasp the blood potassium and kidney function, do not wait until the patient appears to be oliguric, anuric, cardiac arrhythmia, or even cardiac arrest before passive resuscitation. In addition, if a patient is found to have high blood potassium, glucose plus insulin; sodium bicarbonate; calcium gluconate and potassium-removing diuretics can be given, together with dialysis treatment, and most patients can heal themselves.
