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.
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
From the Case Files of SJRMC ED • SH: lives in NH rehab, tobacco 30 pack year history stopped 10 years ago • FH: Unremarkable
SJRMC Case • Vital signs: T: 97.6, P: 76, R: 18 BP 100/50 pulse ox 95% RA • Note the unstable vital signs!
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
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
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
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
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
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
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
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
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
Antibiotic Selection • Ceftazidime /Cefepime • 3rd and 4th generation Cephalosporins (respectively). • Gram negative>Gram Positive coverage. • Good Pseudomonas coverage. Sepsis in the Emergency Department
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
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
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
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
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
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
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
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
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
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
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
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.
