OBJECTIVES
• To understand and be able to identify the differences between SIRS, Sepsis, Severe Sepsis, and Septic Shock.
• To understand the morbidity and mortality of Sepsis in relation to length of stay, current guidelines, cost to health care systems.
• To understand modalities of treatment which include management, such as fluid resuscitation and pharmacological interventions.

SEPSIS ECONOMICS
Sepsis is a major and economically significant disease in the ICU,
costing over $20 billion in the United States in 2011 (5.2% of all U.S.
hospital costs) with costs growing to over $23 billion in 2013 (6.2% of all
U.S. hospital costs)
SEPSIS ECONOMICS

prevalence, high costs, and poor

HISTORICAL PERSPECTIVE
Source: CHEST 1992
SIRS Criteria ( > 2)• Temperature > 38 C < 36
C• Heart rate > 90 bpm• Respiratory rate > 20 /min
or a PaCO2 < 32 mmHg• White blood cell count >
12,000 / cu mm or < 4,000 / cu mm, or > 10 bands
NEW SEPSIS DEFINITION
• Guidelines were revised in 2008, 2012, and most recently updated in 2015.
• These guidelines have shaped how hospitals must identify and treat patients who are identified as having sepsis, severe sepsis, and septic shock.
NEW SEPSIS DEFINITION
The Surviving Sepsis Campaign (SSC) international guidelines were developed for early detection and treatment
of severe sepsis and septic shock

RESEARCH RECOMMENDATION
SCCM recommends that, in the resuscitation of sepsis-induced
hypoperfusion, at least 30 ml/kg of IV crystalloid fluid be given within the first 3 hours (strong recommendation,
low quality of evidence).
ANTIBIOTIC THERAPY
• Started within 3 hrsafter severe sepsis presentation
• Monotherapy vs. Combination Therapy
• Choose Aminoglycosides or Aztreonam or Ciprofloxacin
• Cephalosporins, (1st and 2nd Generation)- or – Clindamycin - or - Daptomycin - or -
Glycopeptides - or - Linezolid - or -
Macrolides - or - Penicillins
COMBINATION THERAPY

CHOICE OF VASOPRESSERS
First Line
Second Line
Niche Drugs
Norepinephrine
Epinephrine Low Dose Vasopressin(.01-.03 units/min)
Dopamine (sinus
bradycardia)
Phenylephrine (high cardiac output
or serious tachyarrhythmias
and salvage)
•We suggest against using IV hydrocortisone to treat septic shock patients if adequate fluid resuscitation and vasopressor therapy are able to restore hemodynamic stability. If this is not achievable, we suggest IV hydrocortisone at a dose of 200 mg per day

•No additional mineralocorticoid
•7 days
•Taper
SURVIVING SEPSIS CAMPAIGN 2016
• Hydrocortisone provides adequate glucocorticoid and mineralocorticoid effects so fludrocortisone is not needed.
• Tapering of steroids is recommended.
• Although the current hypothesis for the use of steroids in septic shock is to treat relative adrenal insufficiency, current evidence suggests no value in measuring this with a corticotropin response test.
WHAT DO WE KNOW?
• Steroids are of no benefit in the treatment of severe sepsis in the absence of shock.
• Low dose steroid therapy reduces time to reversal of septic shock
• Still controversial as to whether or not there is a meaningful reduction in mortality.
• The more severely ill and hemodynamically unstable the patient is the more likely to benefit from stress-dose steroids.
