Sepsis is a life-threatening condition caused by the body's response to an infection. It occurs when an infection you already have triggers a chain reaction throughout your body. Sepsis is diagnosed when a person has both an infection and signs of a systemic inflammatory response. Treatment involves administering broad-spectrum antibiotics intravenously, giving intravenous fluids, and using vasopressors if blood pressure is too low. Preventive measures include vaccinations, early nutrition, immunonutrition, and proper wound and infection care.

5. SEPSIS

6. SIRS
 SIRS – systemic inflammatory response
syndrome
 Must have at least 2 of the following:
 Temperature >38.5ºC or <36ºC
 Heart rate >90 beats/min
 Respiratory rate >20 breaths/min or PaCO2 <32
mmHg
 WBC >12,000 cells/mm3, <4000 cells/mm3, or >10
% immature (band) forms
 SIRS is the body’s response to infection,
inflammation, stress.

8.  a fever above 101ºF (38ºC) or a temperature
below 96.8ºF (36ºC)
 heart rate higher than 90 beats per minute
 breathing rate higher than 20 breaths per
minute
 probable or confirmed infection

9. SEVERE SEPSIS
 patches of discolored skin
 decreased urination
 changes in mental ability
 low platelet (blood clotting cells) count
 problems breathing
 abnormal heart functions
 chills due to fall in body temperature
 unconsciousness

10. RISK FACTORS
 Older adults
 Pregnant women
 Are very young or very old
 Have a compromised immune system
 Have diabetes or cirrhosis
 Are already very sick, often in a hospital intensive
care unit
 Have wounds or injuries, such as burns
 Have invasive devices, such as intravenous catheters
or breathing tubes
 Have previously received antibiotics or corticosteroids

11. SIGN AND SYMPTOMS
 Change in mental status
 A first (upper) number in a blood pressure
reading — also called the systolic pressure
— that's less than or equal to 100 millimeters
of mercury (mm Hg)
 Respiratory rate higher than or equal to 22
breaths a minute

12. DIAGNOSIS
 Urine. If your doctor suspects that you have a urinary tract infection, he or she may want to
check your urine for signs of bacteria.
 Wound secretions. If you have a wound that appears infected, testing a sample of the wound's
secretions can help show what type of antibiotic might work best.
 Respiratory secretions. If you are coughing up mucus (sputum), it may be tested to determine
what type of germ is causing the infection.
 Imaging tests
 If the site of infection is not obvious, your doctor may order one or more of the following imaging
tests:
 X-ray. X-rays are good for visualizing problems in your lungs.
 Computerized tomography (CT). Infections in your appendix or pancreas are easier to see on
CT scans. This technology takes X-rays from a variety of angles and combines them to depict
cross-sectional slices of your body's internal structures.
 Ultrasound. This technology uses sound waves to produce real-time images on a video monitor.
Ultrasound may be particularly useful to check for infections in your gallbladder or ovaries.
 Magnetic resonance imaging (MRI). MRIs may be helpful in identifying soft tissue infections.
This technology uses radio waves and a strong magnet to produce cross-sectional images of the
internal structures of your body.

13. SEPSIS CRITERIA
 fever of more than 100.4°F (38°C) or less
than 96.8°F (36°C)
 heart rate of more than 90 beats per minute
 respiratory rate of more than 20 breaths per
minute or arterial carbon dioxide tension
(PaCO2) of less than 32 mm Hg
 abnormal white blood cell count

14. SOFA SCORE
 Respiration: PaO2/FiO2 or SaO2/FiO2
 Coagulation: Platelets
 Liver: Bilirubin
 Cardiovascular: Hypotension or vasopressor
 CNS: GCS
 Renal: Creatinine or urinary output

15. QUICK SEQUENTIAL ORGAN FAILURE
ASSESSMENT (QSOFA).
 It uses the results of three criteria:
 low blood pressure.
 high respiratory rate (greater than 22 breaths
per minute)
 Glasgow coma scale score of less than 15

17. TREATMENT
 Antibiotics. Treatment with antibiotics should begin immediately. Initially
you'll receive broad-spectrum antibiotics, which are effective against a
variety of bacteria. The antibiotics are administered intravenously (IV).
 After learning the results of blood tests, your doctor may switch to a
different antibiotic that's targeted to fight the particular bacteria causing
the infection.
 Intravenous fluids. People who have sepsis often receive intravenous
fluids right away, usually within three hours.
 Vasopressors. If your blood pressure remains too low even after
receiving intravenous fluids, you may be given a vasopressor
medication, which constricts blood vessels and helps to increase blood
pressure.
 Other medications you may receive include low doses of corticosteroids,
insulin to help maintain stable blood sugar levels, drugs that modify the
immune system responses, and painkillers or sedatives.
 Antimicrobial therapy

18. NEW MODALITIES
 Fibrates (fenofibrates) are used anti-
inflammatory activities through peroxisome
proliferator-activated receptor alpha
activation.
 Levosimendan.
 salbutamol, aliskiren, amiodarone, lithium,
montelukast, alpha-lipoic acid, and sildenafil

19. PREVENTIVE MEASURES
