Systemic infection symptoms

Introduction The symptoms of systemic infection are due to the interaction between the body and the pathogen. Due to the weak immune function of the body, the pathogen cannot be restricted to the local area, so that the pathogen and its toxin spread to the surroundings, and the lymphatics or directly invade the bloodstream, causing systemic infection. The main manifestation is that the systemic metabolic rate slows down. It is an endocrine and metabolic disease, lack of tissue specificity and organ specificity of endocrine and metabolic diseases. The hormone secreted by the endocrine glands enters the blood circulation and exerts its physiological effects as it reaches the various organs and tissues of the body.

Cause

Invasive oral tissue surgery or routine dental procedures, infection of the lower urinary catheter, abscess incision and drainage and built-in bacterial growth, especially intravenous and intracardiac catheters, catheters and ostomy built-in Both the device and the catheter can cause transient bacteremia. Typical Gram-negative bacteremia is intermittent and opportunistic, although this bacteremia may not affect healthy people, but patients with impaired immune disease and severe disease, post-chemotherapy patients, and severe malnutrition , can have serious consequences. The initial site of infection is usually in the lungs, genitourinary tract, gastrointestinal tract or soft tissue, including skin with acne ulcers. It can also occur in dangerous people, especially after dental surgery in patients with valvular heart disease, prosthetic heart valves or other endovascular prostheses.

Blood and bone marrow bacterial culture anaerobic bacteria detection

Pus or body fluids should be obtained from all infected sites, including infected body cavities, joint spaces, soft tissues, and diseased skin for Gram staining and culture. Blood culture should include aerobic and anaerobic cultures. Blood culture should be performed twice a day at intervals of one hour. Blood should be taken from different sites at each time. Two blood cultures are sufficient for the initial diagnosis of bacteremia, but negative staining or culture results cannot exclude bacteremia, especially in patients who have previously received antibiotics, and cannot exclude bacteremia. This specimen of at least 2 blood cultures should be taken from a properly prepared venous incision site. In addition, specimens of sputum, catheter insertion sites and wounds can be cultured.

Differential diagnosis

Potential poisoning: refers to the physiological, biochemical and pathological changes of the body caused by long-term repeated entry into the body under the dose conditions that do not cause acute poisoning, and the clinical symptoms, signs of poisoning or disease state.

Acute poisoning: a large number of poisons enter the human body through the skin, mucous membranes, respiratory tract, digestive tract and other means in a short time, causing damage to the body and dysfunction, called acute poisoning. Acute poisoning is a common clinical emergency. Its condition is rapid and rapid, and diagnosis and first aid treatment must be made as soon as possible.
