Revision as of 17:50, 5 April 2015
Background
- Pancreatitis may appear identical to sepsis
- Infection sources:
- Pulm, skin, GU (account for 80%), abd, CNS
- Childbearing age woman: septic abortion, postpartum endometritis
- No obvious source: consider bacteremia, endocarditis
- Pulm, skin, GU (account for 80%), abd, CNS
Clinical Presentation
SIRS
- 2 or more of the following:
- Temp >38.3 or <36
- HR >90
- Resp rate >20 or CO2 <32
- WBC >12K, <4K, or >10% bands
Sepsis
- SIRS + documented or suspected infection
Severe sepsis
Sepsis AND 1 or more of the following signs of organ dysfunction:
- Lactate > upper limit of normal
- Urine output <0.5 mL/kg for >2hr, despite adequate fluid resuscitation
- Cr >2 (presumed to be new)
- Bilirubin >2 (presumed to be new)
- Plt <100K (presumed to be new)
- INR >1.5 (presumed to be new)
- Acute Lung Injury
- PaO2/FIO2 <250 in absence of PNA as infection source
- PaO2/FIO2 <200 in presence of PNA as infection source
Septic shock
- SBP <90 after adequate fluid challenge OR
- Lactate >4
Differential Diagnosis
- Adrenal Insufficiency
- Salicylate Toxicity
- Anticholinergic Toxicity
- Neuroleptic Malignant Syndrome
- Malignant Hyperthermia
- Thyrotoxicosis
Shock
- Cardiogenic
- Acute valvular Regurgitation/VSD
- CHF
- Dysrhythmia
- ACS
- Myocardial Contusion
- Myocarditis
- Drug toxicity (e.g. beta blocker, CCB, or bupropion OD)
- Obstructive
- Distributive
- Hypovolemic
- Severe dehydration
- Hemorrhagic shock (traumatic and non-traumatic)
Diagnosis
Work-Up
- CBC
- UA/Urine culture
- Blood culture
- CXR
- Chem
- LFT
- Lipase
- VBG
- Lactate
- Coags
- DIC panel (fibrinogen, D-dimer, FDP)
- T&S
- ?CT head/LP
Time Specific Management
Time of presentation is defined as the time of triage in the emergency department
3 hour goals[1]
- Measure lactate level
- Obtain blood cultures prior to administration of antibiotics
- Administer broad spectrum antibiotics
- Administer 30ml/kg crystalloid for hypotension or lactate ≥4mmol/L
6 hour goals
- Apply vasopressors (for hypotension that does not respond to initial fluid resuscitation) to maintain a mean arterial pressure (MAP) ≥65mmHg
- If persistent hypotension after initial fluid administration (MAP < 65 mm Hg) or if initial lactate was ≥4 mmol/L, reassess volume status and tissue perfusion:
- Repeat focused exam OR any two of the following:
- Measure CVP
- Measure ScvO
- Bedside cardiovascular ultrasound
- Dynamic assessment of fluid responsiveness with passive leg raise or fluid challenge
- Repeat focused exam OR any two of the following:
A central line and measurement of ScvO2 is not required and does not impact mortality[2][3][4]
Circulation
- IVF - Reassess after each bolus
- Average is 5-6L w/in first 6hr
- Careful reassessment of volume status is required in in patients with significantly depressed ejection fraction.
Pressors
- Indicated if MAP<60 despite adequate IVF or if IVF are contraindicated
- Best if given when the vascular space is filled; ok if it's not
- Options:
- Norepinephrine (5-20mcg/min) - 1st line
- Epinephrine (1-20 mcg/min) - 2nd line
- Vasopressin (0.03 units/minute fixed dose) can be added to norepinephrine (NE)
Inotropes
- Dobutamine (2-20mcg/kg/min) may be added if:
- Myocardial dysfunction as suggested by elevated cardiac filling pressures and low cardiac output
- Ongoing signs of hypoperfusion, despite achieving adequate intravascular volume and adequate MAP
Steroids
- Controversial and only shown to relieve shock faster in those who have resolution of shock but may increase the risk of infection
- Consider hydrocortisone 50-100mg in ED (200-300 mg qd in 2-4x/d dosing) if pressor/fluid resistant (SBP < 90 persistently)
- ACTH cosyntropin testing likely unreliable in critically ill patients
- Do not administer steroids for the treatment of sepsis in the absence of shock
Infection Control
- Source Control
- Remove infected lines, surgery if indicated
Antibiotics
- Administer within 3 hours
- See Initial Antibiotics in Sepsis (Main)
Blood Products
RBCs
Only transfuse RBCs when hemoglobin decreases to <7.0 g/dL (goal is 7.0 –9.0 g/dL in adults)
Erythropoietin
Do not use erythropoietin as a specific treatment of anemia associated with severe sepsis
Platelets
- In severe sepsis, administer platelets prophylactically when counts are <10,000/mm3 (10 x 109/L) in the absence of apparent bleeding
- If < 20,000/mm3 (20 x 109/L) and significant risk of bleeding then administer platelets.
- <50,000/mm3 (50 x 109/L) if there is active bleeding, planned surgery or other procedures.
