IMPACT OF SEPSIS ON PATIENT OUTCOMES

Educational Content

Epidemiology

• Over 18 million cases worldwide each year • The annual incidence in the US of severe sepsis is approximately 3.0 cases per 1,000 • Sepsis kills approximately 1,400 people worldwide EVERYDAY

Epidemiology-Pediatric

• Sepsis is a leading cause of illness & death among U.S. children • • > 42,000 cases annually (4 th leading cause behind asthma, appendicitis, and poisonings) 5-10% overall mortality (0-5% healthy children; 10% if underlying medical conditions) • 7-9 % of all childhood deaths are due to sepsis (more common than cancer) Watson Am J Respir Crit Care Med 2003 167:695-701 Kutko Pediatr Crit Care Med 2003; 4:333-337 Carcillo Crit Care Med 2002 30(6):1365-1378

Sepsis Disease Spectrum

Presentation of sepsis reflects a spectrum SIRS Sepsis Severe Sepsis Septic Shock

Definitions

•

Systemic Inflammatory Response Syndrome (SIRS): 2 of 4 criteria

• • Temp <36 or >38.5

HR >2 SD above normal for age (or bradycardia if <1 year old*) • • RR > 2 SD above normal for age Abnormal WBC or > 10% immature neutrophils •

Sepsis

: SIRS with suspected or confirmed infection •

Severe sepsis:

Sepsis + organ dysfunction or failure Goldstein Pediatr Crit Care Med 2005 6(1):2-8

•

Definitions

Septic shock= Hypothermia or hyperthermia and signs of cardiovascular organ dysfunction including

• Altered or decreased mental status (inconsolable irritability, lack of interaction with parents and inability to be aroused) • Capillary refill ≥3sec (cold shock) or flash capillary refill (warm shock) • Diminished (cold shock) or bounding peripheral pulses (warm shock) • Mottled cool extremities (cold shock) • Decreased urine output <1 mL/kg/hr • Hypotension Carcillo Crit Care Med 2002 30 (6):1365-1378

2 Major Types of Septic Shock

•

Cold Shock

• Cold extremities •

Warm Shock

• Warm extremities • Capillary refill ≥ 3 sec • Flash capillary refill • Myocardial Dysfunction • Vasomotor Paralysis • Low CI and high SVRI • High CI and low SVRI • Sick heart with significant vasoconstriction to maintain perfusion to organs • Hyperdynamic heart with vasodilation

Definitions

•

Compensated shock

:

• Systolic blood pressure within normal range with signs and symptoms of inadequate perfusion • Children more often present in compensated shock •

Decompensated shock

:

• Signs of shock associated with systolic hypotension

Further Definitions

• Fluid-refractory shock: • Shock despite 60 cc/kg in 1 st hour • Dopamine-resistant shock: • Shock despite adequate fluid resuscitation and 10 mcg/kg/min • Catecholamine-resistant shock: • Shock despite epinephrine or norepinephrine • Refractory shock: • Shock despite goal-directed use of inotropic agents, vasopressors, vasodilators, and maintenance of metabolic and hormonal homeostasis Carcillo Crit Care Med 2002 30 (6):1365-1378

Sepsis: A Disease Continuum

• Patients with life-threatening infection often present with fever and excessive, persistent tachycardia • Tachycardia, tachypnea, and signs of worsening perfusion precede hypotension • • Hypotension is a late, ominous sign in pediatrics Often followed by cardiopulmonary collapse • Stopping progression to hypotension (decompensated shock) via early aggressive interventions improves outcomes

EVIDENCED BASED GUIDELINES

Educational Content

Pediatric Septic Shock Guidelines

• • • • Early aggressive fluid resuscitation (up to 60 cc/kg in the first 15 minutes) • Proportionally larger quantities of fluid in children • • Initial volume resuscitation commonly requires 40-60 cc/kg but can be as much as 200 cc/kg in the 1 st hour Reassess between boluses for signs of volume overload— hepatomegaly, rales, gallops Vasoactive agents for fluid refractory shock • Can be given through peripheral IV until central access is obtained • Initiate dopamine for fluid-refractory shock • • Initiate norepinephrine (warm shock) or epinephrine (cold shock) for fluid-dopamine-refractory shock Remember short half life therefore rapid titrations are needed Hydrocortisone for adrenal insufficiency Identify need for invasive cardiovascular monitoring for fluid-refractory shock Carcillo Crit Care Med 2002 30(6):1365-1378

Pediatric Septic Shock Guideline

• Therapeutic goals include: • Capillary refill time ≤ 2 seconds • Normal pulses with no differential between peripheral and central pulses • Warm extremities • Urine output > 1 cc/kg/hr • Normal mental status • Normal blood pressure for age

ACCM Guidelines: 60 cc/kg in 15 minutes PALS Guidelines: 60 cc/kg in 60 minutes

TRIAGE TRIGGER TOOL

High Risk Conditions Vital Signs Signs of Perfusion

TRIAGE TRIGGER TOOL

Identify as at risk for sepsis if: 1. Hypotension or 2. Meets 3/8 criteria or 3. Meets 2/8 criteria if high-risk

Intubation and Septic Shock

• Low threshold for ET intubation even without primary respiratory failure • Up to 40% of cardiac output may be devoted to work of breathing; this can be unloaded • Atropine, ketamine preferred agents for sedation • Caution with etomidate
