As the temperature continues to rise in summer, the number of patients who visit the diarrhea clinic for acute diarrhea has increased to varying degrees, and in our hospital, it has increased by 12% compared with the previous period. Therefore, it is necessary to remind and draw attention to the fact that inappropriate treatment increases the difficulty of clinical treatment, aggravates the symptoms and even delays the best time for treatment. 1, diarrhea that diarrhea clinical found that many patients to stop diarrhea as one of the diarrhea “cure” measure, because of this, the early application of antidiarrheal drugs is the first choice of many patients with acute diarrhea, which is one of the biggest misunderstanding or error. What is interesting clinically is that although the number of diarrhea is obviously reduced and the amount of stool is not much in patients with early antidiarrhea, in contrast, the number of diarrhea is still more in those who do not have early antidiarrheal treatment, and the amount of stool is also more dilute, and the symptoms seem to be reduced. It is easy to cover up the hidden condition behind the diarrhea and delay the treatment. After all, diarrhea itself causes a large amount of body fluids to be lost through the digestive tract, and timely replenishment of sufficient fluids is a seemingly simple but learned issue, and the learning lies in the occurrence of a large amount of electrolyte loss at the same time, which can cause the internal environment of the human body to be disturbed. Disorders, light hydration without replenishing the corresponding electrolytes can not really correct the water-electrolyte disorders, people with life experience in a large number of sweating or diarrhea will be self-administered with warm light saline oral, the reason is this. 3, abuse of antimicrobial diarrhea in daily life as a common symptom, is often considered a common disease, it is common, most patients through their own “experience” or other people’s narrative advice and other ways to gain knowledge of the disease, and their knowledge is almost focused on antibacterial drugs, so the abuse of antimicrobial phenomenon is quite common. The safety and effectiveness of antimicrobial agents and the indications for their application should be conducted under the guidance of doctors. 4, human hygiene habits need to be strengthened Acute infectious diarrhea is caused by bacteria, viruses, parasites, etc.. Mainly through water, food transmission, poor dietary habits and personal hygiene can also lead to the onset of infection. People should pay attention to prevention when dining out and traveling, such as not drinking raw water, not eating unclean, corrupt, unlicensed and unhygienic food; pay attention to washing hands before and after meals, so as to effectively prevent the occurrence of infectious diarrhea. The last point to remind is that patients with acute diarrhea should regulate their diet and give easily digestible food to reduce the burden on the stomach and intestines, and pay attention to the fact that acute diarrhea should not be hastily supplemented because it is often not achieved quickly.
