Diarrhea that requires antibiotic treatment includes bacillary dysentery, cholera, salmonella enteritis in infants and children, as well as various kinds of severe diarrhea and diarrhea in immunocompromised people. So, before the report of the stool test result is out and the diagnosis is not clear, how can we roughly determine whether antibiotics should be used or not? 1, look at the stool properties, if the stool with pus and blood, must be used antibiotics. 2, <12 years old children with diarrhea, sudden fever, pale face, cold limbs, muscle tightness, such dysentery, must use strong antibiotics, such as cephalosporin antibiotics. 3, some special groups of diarrhea patients apply antibiotics, such as severe diabetes, leukemia, liver cirrhosis, advanced cancer patients and the elderly. The fact that 70% of diarrhea patients do not need antibiotics does not mean that they do not need medication, and some drugs are effective for diarrhea patients. Intestinal mucosal protectors and microecological modulators can help treat diarrhea. Intestinal mucosal protective agents The common ones are Simethicone. After oral administration, these drugs cover the surface of intestinal mucosa extensively, fixing and adsorbing harmful pathogens and toxins, making it difficult for pathogens to invade the intestinal wall, protecting and promoting the regeneration and repair of intestinal mucosa. Micro-ecological regulators Commonly used are Pepcidone, Meconium, etc. There are many normal bacteria in the human body, such as bifidobacteria and fecal bacteria, which are mainly distributed in the intestine and are indispensable for human life activities. If the number of normal bacteria decreases or the ratio is out of balance, the growth of harmful bacteria will increase and diarrhea will further aggravate the imbalance of flora. Microecological preparations are normal bacteria in the intestine mainly Bifidobacterium and Lactobacillus, etc. After oral administration, they can be supplemented to restore the number of normal flora and serve the purpose of treating diarrhea.
