সংজ্ঞা
Blood poisoning is an illness due to an infection or its toxin spreading through the bloodstream. The presence of bacteria in the blood is called bacteremia.
Short bursts of low levels of bacteria in the blood usually do not cause problems. However, if bacteria levels do not decrease sepsis may occur. This is a serious condition which can lead to death.
কারণসমূহ
Sepsis occurs when large numbers of infectious agents exist in the blood. Infections with fungi and parasites may lead to sepsis as well. The initial infection often comes from:
- A burn, ulcer, or other open wound
- নিউমোনিয়া
- A urinary tract infection
Bacteria can also enter the bloodstream directly from an outside source. A dirty needle used by an IV drug user can cause this type of infection. In some cases, the source of the infection is unknown.
Small amounts of bacteria enter into the blood with dental work or when brushing your teeth. Your body’s immune system should fight off these bacteria.
ঝুঁকির কারণ
Factors that increase your chance of getting sepsis include:
- Recent illness or hospital care
- Frail health due to increased age
- Poorly working immune system due to:
- Cancer or chemotherapy to treat cancer
- ডায়াবেটিস
- AIDS or another immunosuppressive condition, such as an autoimmune disease or an immune deficiency
- Immunosuppressive medications needed after a transplant
- Medical treatment with an invasive device
- IV drug abuse
লক্ষণ
The first symptoms depend on the site of the infection.
As the condition progresses to sepsis, symptoms include:
- জ্বর এবং সর্দি
- Low temperature
- Paleness of skin color
- Listlessness
- Changes in mental status
- দ্রুত শ্বাস - প্রশ্বাস
- Increased heart rate
- Decreased urine
- নিম্ন রক্তচাপ
- শক
- Problems with bleeding or clotting
রোগ নির্ণয়
The doctor will ask about your symptoms and medical history and perform a physical exam. If sepsis is suspected, the doctor will try to find the source of the infection.
Tests include:
- Several blood cultures to confirm the diagnosis of sepsis
- Urine and other blood tests to check for signs of infection
- Cultures of urine, sputum, stool, and other secretions to check for bacteria or other infectious agents
- এক্স-রে- এমন একটি পরীক্ষা যা শরীরের অভ্যন্তরে কাঠামোর ছবি তুলতে বিকিরণ ব্যবহার করে
- CT scan—a type of x-ray that uses a computer to make pictures of structures inside the body
- MRI scan—a test that uses magnetic waves to make pictures of structures inside the body
- Other specialized tests depending on the source of the infection
চিকিৎসা
This condition will need to be treated aggressively. Treatment is aimed at the cause of the initial infection.
Early treatment improves the chance of survival. Life-saving steps may be needed to assist breathing and heart function. Patients usually need to be observed in an intensive care unit.
ঔষধ
IV antibiotics will be used to fight the initial infection and to clear it from your blood. You will be given oral antibiotics when you leave the hospital.
সার্জারি
Surgery is sometimes needed to remove or drain the initial infection.
সহায়ক যত্ন
You will likely receive other medications, IV fluids, and oxygen. If your blood pressure remains too low, you may need vasopressors—medicines to help maintain your normal blood pressure. Blood transfusions and a respirator (to help you breathe) may be necessary in some cases.
Further treatment depends on how your body is responding. For example, you may need kidney dialysis if kidney failure occurs.
প্রতিরোধ
It is not always possible to prevent blood poisoning. Avoiding IV drug abuse decreases your chance of sepsis. Healthcare professionals must also take steps to stop the spread of these infections. Getting prompt medical care for infections can reduce your risk of sepsis.
