  1. Emergency Department Management of Sepsis in the 21st Century Otto F Sabando D.O. FACOEP Program Director Emergency Medicine Residency Saint Joseph Regional Medical Center Paterson NJ Sepsis in the Emergency Department

  2. Sepsis in the Emergency Department • Conflicts to report • None Sepsis in the Emergency Department

  3. Scope of Problem • ED visit related to sepsis 1992- 2001 • 2.8 million out of 712 million visits over a 10 year period. • Severe sepsis diagnosed in about 10% of these sepsis patients. • Approximately 1.5 sepsis related visits\1000 pop. • Top chief complaints: fever, dyspnea, generalized weakness. • Septic Shock Mortality 25-40% Sepsis in the Emergency Department

  4. Scope of Problem • More recent evidence suggests a larger problem • 750,000 cases per year. • 250,000+ deaths. • Incidence increases with age. • Yearly number expected to grow as population ages. Sepsis in the Emergency Department

  5. Scope of Problem • Baby Boomers: • 78 million eligible for Medicare starting in 2011 • Rate will be 10000/day beginning 2011

  6. Scope of Problem • SJRMC • Urban, tertiary care hospital. • 92,000 ED visits in 2007. • 18,000 admissions from ED. • 403 severe sepsis\septic shock patients • 323 from ED. • 80 already admitted patients. Sepsis in the Emergency Department

  7. Scope of Problem • SJHMC • Infectious origin • 40% pneumonia • 13% UTI • 8% abdominal infections • 39% other infections • Mortality • 48% prior to “Stomp Sepsis” • 28% overall mortality • 25% mortality of those admitted from ED Sepsis in the Emergency Department

  8. Sepsis in the Emergency Department Define SIRS, sepsis, severe sepsis, septic shock and MODS. Define early goal-directed therapy. Discuss appropriate antibiotic usage in treatment of sepsis. Discuss adjunctive medications used in the treatment of septic shock. Sepsis in the Emergency Department

  9. Definitions • The Continuum • SIRS • Sepsis • Severe Sepsis • Septic Shock Sepsis in the Emergency Department

  10. Definition - SIRS • Systemic Inflammatory Response Syndrome • Manifested by 2 or more of the following: • Temperature > 38°C (100.4F) or < 36°C (96.8F) • HR > 90 BPM • RR > 20/min or PaCO PaCO2 < 32 mm Hg • WBC 12,000 or >10 bands Systemic Sepsis in the Emergency Department

  11. Definition - Sepsis • Sepsis • SIRS PLUS a documented infection • Positive CXR • Positive U/A • Cellulitis /Abscess • Positive Blood Culture Sepsis in the Emergency Department

  12. Definition – Severe Sepsis • Severe Sepsis • One Sepsis related organ dysfunction (non-chronic) and/or: • Signs of hypoperfusion (Lactate>2, oliguria , altered mental status, mottling, desaturation, elevated LFT’s) AND/or • Hypotension • SBP <90 • MAP<60 Sepsis in the Emergency Department

  13. Definition – Septic Shock • Septic Shock • Severe sepsis with persistent hypotension (refractory to fluid bolus) or: • Acute circulatory failure in an infected patient not explained by another cause . • Significant vasodilation (low SVR) is primary cause of hypotension . • Heart rate, CO, and Stroke Volume are usually good . Sepsis in the Emergency Department

  14. Definition - MODS • MODS - Multiple Organ Dysfunction Syndrome • More than one major system failure. • Related to significant mortality. • > 50% Sepsis in the Emergency Department

  15. From the case files of SJRMC ED

  16. From the Case Files of SJRMC ED • CC: Fever • 88 y.o. male sent in by BLS for evaluation of fever. He states that he was discharged from the hospital 1 week ago for pneumonia. Today he had fever, noted by the atrium to be 103 orally and treated with Tylenol. His appetite is decreased and has no pain and no other complaints.

  17. From the Case Files of SJRMC ED • PMH: Hypertension, pneumonia, CAD with pacemaker/defibrillator in place, anemia, gout, GERD, and enlarged prostate • Allergies: NKDA • Meds: Procrit, singulair, toporol XL, vitamin C, Allopurinol, cyanocobalamin, furosemide, hydroxyzine, magnesium, omeprazole

  18. From the Case Files of SJRMC ED • SH: lives in NH rehab, tobacco 30 pack year history stopped 10 years ago • FH: Unremarkable

  19. SJRMC Case • Vital signs: T: 97.6, P: 76, R: 18 BP 100/50 pulse ox 95% RA • Note the unstable vital signs!

  20. Treatment of Septic Shock • Appropriate identification leads to more appropriate treatment. • Hypoperfusion – are we aggressive enough in the emergency department? • Source of infection • knowing local pathogens. • Delays in abx administration. Sepsis in the Emergency Department

  21. Sepsis in the Emergency Department

  22. Treatment of Septic Shock • Identification • Continuous monitoring • Pulse, blood pressure, pulse ox, urine output • Laboratory tests • Blood and urine cultures. • Lactate Acid (a marker of tissue hypoxia) • Chest Radiography • Pneumonia makes up a large portion of the cases. • Remember – initial complaints can be nonspecific. Sepsis in the Emergency Department

  23. Treatment of Septic Shock • Identification – Search for source • Lung-Pneumonia/Lung Abscess • UTI/Pyelonephritis • Heart -Endocarditis • Abdomen-Bowel Perforation • Brain-Meningitis • Bone-Osteomyelitis • Cellulitis • Pressure ulcers Sepsis in the Emergency Department

  24. Current Two weeks ago

  25. Treatment of Septic Shock • Initiate broad-spectrum\Site specific antibiotics • Goal is administration within three hours of arrival in ED. • Several studies support the concept of “earlier the better” • Early\Appropriate antibiotics appear to affect outcomes. • Cochrane paper underway on subject Sepsis in the Emergency Department

  26. Treatment of Septic Shock • Antibiotic Choices • Base on suspected pathogen information. • Remember previous cultures on your patient! • Adapt to local pathogens\antibiotogram. • Consider MRSA coverage • Many institutions routinely include. • Many paths to same destination. Sepsis in the Emergency Department

  27. Antibiotic Selection • Pneumonia • 3rd generation or greater fluoroquinolone • Levofloxacin (750mg), Moxifloxacin (500mg) • + Vancomycin • +\- Gentamicin • Linezolid • good coverage for VRE, MRSA, Strep. Pneumo. • Piperacillin\Tazobactam • Consider adding an aminoglycoside for pseudomonal coverage. Sepsis in the Emergency Department

  28. Antibiotic Selection • Urinary Tract Infection • Piperacillin\Tazobactam (3.375 – 4.5 grams q6) • + Gentamicin (7 mg\kg, q24hours) • May substitute ceftazidime, cefepime, aztreonam, imipenem, or meropenem. • Meningitis • Dexamethasone 10mg IV (before ABX) • Vancomycin 1 gram IV • Ceftriaxone 2 grams IV Sepsis in the Emergency Department

  29. Antibiotic Selection • Vancomycin • Only Gram Positive coverage. • Best for resistant strains of Strep (MRSA). • Rarely used alone . • Linezolid • In a new class of antibiotics ( oxazolidinones ). • Primarily covers aerobic Gram positive organisms (including MRSA). • Strep pneumoniae (including multi multi-drug resistant strains). • Enterococcus faecium (including VRE). Sepsis in the Emergency Department

  30. Antibiotic Selection • Piperacillin/Tazobactam • Semi -synthetic penicillin plus a β Lactamase inhibitor. • Gram positive and some Gram neg. and anaerobes. • Used with an aminoglycoside for Pseudomonas. • 3.375 grams to 4.5 grams IVPB Q 6hrs Sepsis in the Emergency Department

  31. Antibiotic Selection • Ceftazidime /Cefepime • 3rd and 4th generation Cephalosporins (respectively). • Gram negative>Gram Positive coverage. • Good Pseudomonas coverage. Sepsis in the Emergency Department

  32. Early Goal Directed Therapy(EGDT) • Study from NEJM November 8, 2001 Rivers, et.al • Patients with severe sepsis and septic shock randomly assigned to get 6 hours EGDT or standard therapy. • In-hospital mortality was 30.5% for EGDT group and 46.5% for standard therapy group. • NNT was 6 to save one additional life. Sepsis in the Emergency Department

  33. Early Goal Directed Therapy • Treatment difference was invasive monitoring of CVP and Central Venous Oxygen Saturation. • No difference in total volume replacement or inotrope use during initial 72 hours. • Front loaded in the treatment group (including use of dobutamine). • Treatment group much more likely to have received blood transfusions. Sepsis in the Emergency Department

  34. Sepsis in the Emergency Department

  35. Early Goal Directed Therapy • In 2004 Surviving Sepsis Campaign • Adapted the original Rivers’ Protocol and other research • Created practice guidelines. • Outlined resuscitation and management bundles. • Stated goal was 25% reduction in mortality. • Severe Sepsis Resuscitation Bundle. • Goal was to perform outlined tasks within six hours. Sepsis in the Emergency Department

  36. Early Goal Directed Therapy • Resuscitation Bundle included: • Measurement of Lactic acid. • Blood cultures prior to antibiotic administration. • Appropriate broad spectrum antibiotics in 3 hours (ED arrival). • IF hypotension • IV fluid bolus (20ml\kg initial) • IF continued hypotension or lactic acid > 4 • Achieve MAP > 65 • Achieve central venous pressure 8 mmHg or greater • Achieve central venous oxygen sat. of 70% Sepsis in the Emergency Department

  37. Early Goal Directed Therapy • Achieve MAP > 65 • Continued fluid boluses. • Adequate fluid resuscitation is a key component. • Initiation of vasopressor agents. • Norepinephrine • Dopamine • Norepinephrine appears to be the more common choice. Sepsis in the Emergency Department

  38. Early Goal Directed Therapy • Norepinephrine • Extensive a-adrenergic response. • Moderate b-adrenergic response. • Works mostly through vasoconstrictive actions. • Does not change heart rate, cardiac output. • 0.05 – 5 microgram\kg\minute (titrated to effect). Sepsis in the Emergency Department

  39. Early Goal Directed Therapy • Achieve CVP 8 mmHg or greater • Goal is 12 mmHg in intubated patients. • Generally measured via an “above the diaphragm” central venous line. • Subclavian • Internal Jugular (preferred for US guided) • Achieved through repeated fluid boluses (normal saline, lactated ringers). Sepsis in the Emergency Department

  40. Early Goal Directed Therapy • Central Venous Pressure • Pressure in Right Atrium . • Reflective of Preload . • Normal between 5 and 10 mmHg. • Can be measured through a standard triple lumen catheter. Sepsis in the Emergency Department

  41. Early Goal Directed Therapy • Achieve central venous oxygen sat. of 70% • Can be drawn from same central line and run in a blood gas analyzer. (intermittent) • Continual monitoring available from a specialized catheter. (PreSep, Edwards) • If Hb less than 10 mg\dl, transfuse PRBCs until you meet this goal. • If Hb already above 10 mg\dl, use dobutamine to achieve this goal. Sepsis in the Emergency Department

  42. Early Goal Directed Therapy • Dobutamine • Inotrope. • Strong beta adrenergic response. • Start at 5 mcg\kg\minute. • Maximum of 20 mcg\kg\minute. • May increase hypotension so norepinephrine may be required to counteract this effect. • Goal is to increase cardiac output. Sepsis in the Emergency Department

  43. Management of Septic Shock in the ED

  44. Early Goal Directed Therapy • Summarizing EGDT • Achieve adequate fluid resuscitation. • Vasopressors to keep MAP > 65 mmHg. • Measure CVP and Central Venous Oxygen Saturation • Additional fluids to achieve adequate CVP. • CV oxygenation as a marker of adequate tissue perfusion • Maximize other parameters first (especially CVP). • If anemic transfuse. • If not anemic consider an inotrope (dobutamine). Sepsis in the Emergency Department

  45. Early Goal Directed Therapy • Summarizing EGDT • Continuing research is being done to fine tune and support this approach. • Clearly being more aggressive is beneficial. • Septic shock patients tended to be under-resuscitated coming out of ED. • Better coordination between ED and ICU is critical.
