Petechiae on the conjunctiva are one of the clinical manifestations of sepsis. The clinical onset of sepsis is rapid, and the rash takes the form of petechiae, urticaria, pustular rash, and scarlet fever-like rash with petechiae on the conjunctiva. Gram-negative coccus sepsis can cause petechiae on the conjunctiva. There are no specific clinical manifestations of sepsis per se, and the manifestations seen in sepsis can also be seen in other acute infections, such as mostly rapid onset, with chills or chills followed by high fever of variable fever, flaccid fever or retention fever; weak, severely malnourished and small infants may have no fever or even a lower than normal temperature. Mental depression or restlessness, or in severe cases, pale or blue-gray face and confusion. In severe cases, the face may be pale or blue-gray, and the mind may be confused. There may be cold extremities, shortness of breath, increased heart rate, decreased blood pressure, and jaundice in infants and children. Some children may have various skin lesions, including petechiae, petechiae, scarlet fever-like rash, and urticaria-like rash. Petechiae or petechiae of varying sizes can be seen in meningococcal sepsis; scarlet fever-like rash is common in streptococcal and Staphylococcus aureus sepsis. The gastrointestinal tract is often characterized by vomiting, diarrhea, abdominal pain, and even vomiting blood and blood in stool; in severe cases, toxic intestinal paralysis or dehydration and acidosis may occur. It is common in infants and young children, with mild or moderate enlargement; some children may be complicated by toxic hepatitis; when the migratory damage of B. aureus causes liver abscess, the liver pressure pain is obvious. Some children may have joint swelling and pain, impaired mobility or joint fluid accumulation, mostly in large joints. Severely ill children often have symptoms of parenchymal organ involvement such as myocarditis, heart failure, confusion, lethargy, coma, oliguria or anuria. Multiple migratory lesions are common in S. aureus sepsis; Gram-negative sepsis is often complicated by shock and DIC. Petechiae, petechiae, pus, cerebrospinal fluid, and thoracoabdominal fluid can also be stained and microscopically examined directly for bacteria.
