Epidemic diarrhea of newborn (epidemicdiarrheaofnewborn) is an outbreak of epidemic diarrhea health search in the maternity ward or hospital neonatal ward health search due to the imperfect immune function of newborns and environmental factors, prone to infection health search pathogens to bacteria, viruses, fungi parasites are more common mainly through the maternal birth canal is contaminated with milk water, nipples It is transmitted by adult carriers of food utensils, etc. How to diagnose the foamy and fishy smelling stool? A, clinical manifestations 1, gastrointestinal symptoms diarrhea several times a day or more than 10 times a day, stool properties related to the pathogen can be dilute watery stool mucus stool, blood-like stool children often have loss of appetite bloating vomiting magpie network. The newborn epidemic diarrhea caused by different pathogens have certain characteristics: (1) Escherichia coli enteritis: pathogenic Escherichia coli enteritis stool for watery, egg-flake soup-like with fishy smell; virulent Escherichia coli enteritis stool for dilute watery; invasive Escherichia coli enteritis stool mucus pus blood-like, fishy smell, stool volume is not much. (2) Salmonella typhimurium enteritis: stool characteristics are variable, can be watery mucous jelly-like, black-green or gray-white with a distinct fishy odor. (3) Rotavirus enteritis: the onset of acute flat magpie network often feverish stool dilute watery flat magpie network amount, fishy odor may not be obvious. (4) Staphylococcus aureus enteritis: stools are mostly yellow-green, dark green, watery, with fishy odor. (5) fungal enteritis: the stool is yellow-green dilute watery, or bean curd-like, foamy. 2, systemic symptoms often feverish depression, crying and restlessness, serious cases appear drowsy, pale lips around the cyanosis. 3, water-electrolyte balance disorders neonatal diarrhea often occur within a short time dehydration acidosis, hyponatremia hypokalemia and other complications flat magpie net serious face gray skin pattern cold extremities, urine less shock. 4, other Some children are accompanied by other parts of the infection, such as pneumonia, otitis media urinary tract infection, thrush, sepsis, etc. Second, diagnosis 1, medical history and prevalence to take a detailed history to understand the epidemiological situation, to help diagnose. 2, clinical manifestations to observe in detail the stool properties. At the same time to closely observe the development of the disease, the degree of neonatal dehydration is difficult to estimate especially for premature infants, subcutaneous fat less, the skin elasticity to estimate dehydration is not accurate, it is best to record the urine volume measurement according to the continuous weight. 3, pathogenic examination should be promptly take specimens for bacterial culture, such as suspected rotavirus infection, to check the virus antigen at the same time, such as suspected fungal infection, fungal spores and mycelia can be seen in the stool microscopy. 4, blood gas analysis and electrolyte examination, neonatal diarrhea is prone to acidosis and electrolyte disorders flat magpie network, blood gas analysis and electrolyte examination should be done in a timely manner to achieve timely treatment.
