Revision as of 20:15, 27 November 2019

Background

  • Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection[1]
  • The infection is most commonly by bacteria, but can also be by fungi, viruses, or parasites[2]
  • Risk of death from sepsis being as high as 30%, severe sepsis as high as 50%, and septic shock as high as 80% [3]
  • The most common primary sources of infection resulting in sepsis are the lungs, the abdomen, and the urinary tract[4]
  • Sepsis carries a 40% in hospital mortality[1]
  • Positive cultures are not obligatory in the diagnosis of sepsis
  • Pneumonia, abdominal abscess and pyelonephritis are common primary causes of sepsis

Definition Changes

In 2016 new definitions were adopted for the evaluation and diagnosis of Sepsis, Severe Sepsis and Septic shock[5]

Old definition New 2016 definition
Sepsis 2 SIRS + suspected infection Life threatening organ dysfunction caused by dysregulated host response to infection. Suspected/documented infection + 2 on the qSOFA:

  3. RR >20 breaths/minute or PaCO2 <32 mmHg
  4. WBC count >12,000/mm3, <4,000/mm3, or >10% bands/immature forms

Clinical Features

Sepsis

Life-threatening organ dysfunction caused by a dysregulated host response to infection. This only needs to include one of the following:[8]

Septic shock

Patients with sepsis and any of the following:[1]

  1. Vasopressor requirement to maintain a mean arterial pressure > 65 mm Hg
  2. Serum lactate level greater than 2 mmol/L (>18mg/dL) in the absence of hypovolemia.

Differential Diagnosis

Shock

Evaluation

Work-Up

Time Specific Management

Time of presentation is defined as the time of triage in the emergency department

3 hour goals[9]

  • 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[9]

  • 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:
    • Option 1: Focused Exam
      • Vital signs
      • Cardiopulmonary Exam
      • Capillary Refill
      • Peripheral Pulse
      • Skin Exam
    • Option 2: Two of the following
      • Measure CVP (IVC ultrasound) with following goals:
        • >8 cmH2O, not intubated
        • >12 cmH2O, intubated
      • Measure ScvO
      • Bedside cardiovascular ultrasound
      • Dynamic assessment of fluid responsiveness with passive leg raise or fluid challenge

A central line and measurement of ScvO2 is not required and does not impact mortality[10][11][12]

Circulation Managment

IVF

  • Guidelines recommend initial 30 cc/kg bolus (generally 2L in average adult)
  • Reassess patient's volume status after initial bolus. Auscultate for pulmonary edema. Evaluate peripheral circulation. Consider IVC ultrasound
  • Septic patients can be euvolemic but remain hypotensive due to vasodilation. Consider early vasopressors.
  • Increasing evidence that excessive fluid resuscitation can be harmful.
    • Positive fluid balance on day 3 of hospital admission independently associated with increasing mortality [13]
    • Protocolized fluid administration (e.g. traditional Early Goal Directed Therapy) has no mortality benefit over usual care. [14] [15]
    • High volume (5+ L) resuscitation associated with increased mortality. [16]
  • Consider assessing diastolic dysfunction via echo in CHF patients in whom IVC ultrasound is not reliable


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 is not

Options:

  • Norepinephrine (5-20mcg/min) - 1st line[17]
  • Epinephrine (1-20 mcg/min) - 2nd line
  • Vasopressin (0.03 units/minute fixed dose) can be added to norepinephrine (NE)
    • as a 2nd line agent may reduce arrhythmia's compared to other pressors with catecholamine properties[18]
  • Dopamine should be used hesitantly and only in highly selected patients (eg, patients with low risk of tachyarrhythmias and absolute or relative bradycardia)
    • Do not use Low-dose dopamine for renal protection
    • Dopamine may have increased mortality rates compared to other vasopressors, especially in the pediatric septic patient[19]
  • Phenylephrine should not be used for treating septic shock except if:
    • Norepinephrine is associated with serious arrhythmias
    • Cardiac output is known to be high and blood pressure persistently low
    • As salvage therapy when combined inotrope/vasopressor drugs and low dose vasopressin have failed to achieve MAP target
  • Milrinone
  • Methylene blue consideration for septic shock refractory to catecholaminergic pressors

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 (200-300mg 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

Esmolol

  • One single-center RCT showing ~40% reduction in mortality when esmolol paired with norepinephrine infusion, with goal HR 80 - 95 BPM[20]
  • All patients were fluid resuscitated, intubated, given hydrocortisone 300 mg/day
  • Will require further multi-center RCTs to confirm findings

Infection Control

Source control

Antibiotics

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.

Disposition

  • Admit, possibly to step-down or ICU
