The quantity of fluid required often far exceeds the normal blood volume and may reach 10 L over 4 to 12 h. PAOP or echocardiography can identify limitations in left ventricular function and incipient pulmonary edema due to fluid overload.

If a patient with septic shock remains hypotensive after CVP or PAOP has been raised to target levels, norepinephrine or vasopressin 0. Epinephrine may be added if a second drug is needed.

However, vasoconstriction caused by higher doses of these drugs may cause organ hypoperfusion and acidosis. Oxygen is given by mask or nasal prongs. Tracheal intubation and mechanical ventilation may be needed subsequently for respiratory failure see Mechanical ventilation in ARDS. Parenteral antibiotics should be given as soon as possible after specimens of blood, body fluids, and wound sites have been taken for Gram stain and culture. Very prompt empiric therapy, started immediately after suspecting sepsis, is essential and may be lifesaving. Antibiotic selection requires an educated guess based on the suspected source eg, pneumonia, urinary tract infection , clinical setting, knowledge or suspicion of causative organisms and of sensitivity patterns common to that specific inpatient unit or institution, and previous culture results.
Typically, broad-spectrum gram-positive and gram-negative bacterial coverage is used initially; immunocompromised patients should also receive an empiric antifungal drug. There are many possible starting regimens; when available, institutional trends for infecting organisms and their antibiotic susceptibility patterns antibiograms should be used to select empiric treatment. In general, common antibiotics for empiric gram-positive coverage include vancomycin and linezolid. Initial broad coverage is narrowed based on culture and sensitivity data. Knowledge of institution- and care unit- specific trends in infecting organisms and their antimicrobial sensitivity is an important guide to empiric antibiotic selection.
The source of infection should be controlled as early as possible. IV and urinary catheters and endotracheal tubes should be removed if possible or changed. Abscesses must be drained, and necrotic and devitalized tissues eg, gangrenous gallbladder, necrotizing soft-tissue infection must be surgically excised. If excision is not possible eg, because of comorbidities or hemodynamic instability , surgical drainage may help. Normalization of blood glucose improves outcome in critically ill patients, even those not known to be diabetic, because hyperglycemia impairs the immune response to infection.
This approach necessitates frequent eg, every 1 to 4 h glucose measurement. Corticosteroid therapy may be beneficial in patients who remain hypotensive despite treatment with IV fluids, source control, antibiotics, and vasopressors. There is no need to measure cortisol levels before starting therapy.
Treatment is with replacement rather than pharmacologic doses. One regimen consists of hydrocortisone 50 mg IV q 6 h or mg q 8 h.
Continued treatment is based on patient response. Trials of monoclonal antibodies and activated protein C drotrecogin alfa—no longer available have been unsuccessful. Sepsis and septic shock are increasingly severe clinical syndromes of life-threatening organ dysfunction caused by a dysregulated response to infection. An important component is critical reduction in tissue perfusion, which can lead to acute failure of multiple organs, including the lungs, kidneys, and liver. Resuscitate with IV fluids and sometimes vasopressors titrated to optimize central venous oxygen saturation ScvO 2 and preload, and to lower serum lactate levels.
Give empiric broad-spectrum antibiotics directed at most likely organisms and switch quickly to more specific drugs based on culture and sensitivity results.

This condition is an infection that is present in one area of the body, such as a tooth, enters the blood and becomes a systemic problem , moving through the body.
Sepsis can start with almost any type of infection, ranging from minor infections urinary tract infection, abscessed tooth, athlete's foot to serious ones meningitis.

Some patients who become septic were completely unaware of their initial infection. With a typical infection, the body responds to the threat of infection, keeping the infection at the site of origin. Treatment with antibiotics is typically the first course of treatment if the body needs the additional help. When the body is unable to contain the infection in the original site, it can spread in the blood, which is sepsis. A patient is typically diagnosed with sepsis after blood cultures indicate that there is an infection in the blood.

Sepsis is rather common and can be treated, in most cases, with antibiotics. Septic shock is a very serious condition that results from uncontrolled sepsis. Septic shock is life-threatening and requires immediate attention. Patients who have septic shock are typically treated in the ICU where they can have around-the-clock care. They often require large amounts of IV fluid, medication to support blood pressure and multiple antibiotics.
People who have sepsis may require hospitalization. In addition to antibiotics, other medications may be used to treat symptoms such as low blood pressure. People whose conditions progress to septic shock often require care in an ICU, where they receive oxygen and IV fluids. They also may need a machine to help them breathe. The longer sepsis is allowed to progress, the higher the chances it will become life-threatening.
Research has shown, however, that if treatment is started within the first few hours from the time sepsis begins, the mortality rate from sepsis falls significantly. That makes early, aggressive treatment of sepsis crucial.
