The Challenge: Understanding Sepsis
In 2002, the European Society of Intensive Care Medicine and the Society of Critical Care Medicine conducted an international survey on 1, 050 physicians worldwide
.The goal was to investigate:Physicians’ views on sepsisSatisfaction with current definitionsRoutes to diagnosisTreatment options
Survey conducted by Yankelovich Partners, Inc.2002.

The Challenge: Understanding Sepsis
Most physicians found sepsis challenging and frustrating to diagnose and treat
.
86% said that symptoms of sepsis can easily be misattributed to other conditions
89% said doctors are eager for a breakthrough in treating sepsis
81% said that a common definition for sepsis among the medical community would be a significant step toward better treatment
Survey conducted by Yankelovich Partners, Inc.2002.

The Response: Surviving Sepsis Campaign
A six point action plan to reduce global mortality from severe sepsis by 25% by 2009:
.Building awareness of sepsis among healthcare professionals, governments, health and funding agencies, and the general publicImproving early and accurate diagnosisIncreasing the use of appropriate treatments and interventionsEducating all healthcare professionals about diagnosis, treatment, and management of sepsisImproving access to post-ICU care for sepsis patientsDeveloping global standards of care

The three published studies reported no benefit for EGDT
The addition of continuous ScvO2 monitoring and strict protocolisation did not improve outcomes in the EGDT group
EGDT was not superior to usual care

Sepsis: Incidence and Costs
Severe sepsis is the leading cause of death in the non-coronary ICU
.More than 27 million cases of sepsis occur each year19 million sepsis victims survived 2014/ at least 1 million more couldSepsis kills some 1,400 people worldwide every dayThe number of sepsis cases is projected to grow at a rate of 1.5% per year as the population ages and medicine become more aggressive (2007 18 mill cases vs. 2014 27 mill cases)The mortality rates are: 12-17% for sepsis, 30-50% for severe sepsis and 50-60% for septic shockAverage cost for sepsis treatment is approximately $22 000

Sepsis: Gastrointestinal Dysfunction
Overgrowth of bacteria in the upper GI tract may be aspirated into lungs ending with nosocomial pneumonia
Paralytic ileus leads to a delay in the institution of enteral feeding
Nutritional intake is interfered with in the face of high protein and calorie requirements
Narcotics and muscle relaxants worse GI tract motility

Sepsis: Treatment
STEP ABC - Airway Breathing Circulation
Resuscitation, volume resuscitation, mechanical ventilationKeeping tissue perfusion and oxygen deliveryKeeping hydrostatic pressure in the lungs low with adequate oxygenation and oxygen delievery to tissues
STEP D - Diagnosis
Define sepsis, obtain blood cultures
STEP E – Empiric antimicrobial therapy
Administer empiric broad spectrum antibiotic
STEP F – Find and control the source of infection
Define the source of sepsis, eliminate the nidus of infection
STEP G – Gut
NG suction, paralytic ileus treatment

STEP H - Hemodynamics
Volume resuscitation, norepinephrine, dobutamine, vassopresine
STEP I – Iatrogenic injuries
Nosocomial infection, iatrogenic pneumothorax
STEP J – Justify your therapeutic plan and reassess
Reassess the patient
STEP KL – Keep Looking: secondary source of infection?
Reassess the patient
STEP MN – Metabolic and Neuroendocrine control
Blood glucose control, electrolytes, nutrition, calories, elements

FLUIDE RESUSCITATION GOALS CVP 8 – 12 mmHg, MAP > 65 mmHg, ScVO2 > 70%
CRYSTALLOIDES VS. COLOIDES; NOREPHINEPHRINE
FLUID OVERLOAD LINKED WITH POOR OUTCOME; 30 mL/kg
Identification and elimination (surgical drainage and/or antibiotics) of the nidus of infection
EVERY DELAY IN 1 HOUR DECREASSES SURVIVAL BY 8%
Interruption of the pathogenic sequence leading to septic shock
LACTATE, PROCALCITONIN

Sepsis
Any kind of infection can lead to sepsis
Quick diagnosis and treatment are the difference between life and death
Know the symptoms, suspect sepsis, save lives!
