    • Temperature greater or equal to 38 or less than 36
    • Altered mental state
    • WBC greater than 12.0 or less than 4.0 x 10/L
  • Sepsis
    Life threatening organ dysfunction caused by a dysregulated host response to infection
  • Sepsis manifestations
    • Skin: cold, clammy, cyanosis
    • CVS: tachycardia, HTN, edema
    • Renal: oliguria: increase BUN and CR
    • Neurological: confusion, disorientation, behavioural changes
    • Respiratory: tachypnea, dyspnea, hypoxemia, pulmonary edema
    • Gastrointestinal: ileus, N&V
  • Nursing assessments for sepsis
    • VS Q1H-2H: watch for hypotension, tachycardia, tachypnea, hypoxia
    • Chest assessment Q1-2H
    • Neuro status
    • Peripheral perfusion
    • Urine output Q1H (100ml per hour could be ideal for a person with septic)
    • Blood work and microbiology results
  • How we diagnose sepsis
    1. Step 1: nursing assessment
    2. Step 2: MD initiates "early sepsis investigation and treatment" orders
    3. MD to review diagnostic results and ongoing assessment data
    4. Calculate organ dysfunction using SOFA tool
    5. Step 4: if positive for infection and SOFA score of 2 or more -> diagnosis of sepsis confirmed
  • Doctors' orders for nursing care

    • Frequent assessment and VS
    • Ensure cultures collected
    • Ensure B/W, especially lactate collected
    • Administer Abx (antibiotic) per orders (after cultures)
    • Oxygenation and RT referral PRN
    • Establish and maintain large-bore IV access
    • Fluid therapycrystalloid then colloid
    • Ongoing communication with PCC and MRP
    • Call ICU outreach team if pt. status deteriorates
  • Sepsis diagnostic bloodwork and micro
    • Blood glucose – elevates in response to stress
    • C-reactive protein – elevates due to overwhelming inflammation
    • Procalcitonin – sepsis biomarker of inflammation from bacterial infection
    • Lactate – elevates d/t anaerobic metabolism
    • Hypoxemia & Alkalosis – o2 decreases, co2 decreases
    • BUN would increase
    • Creatinine would increase
    • eGFR would decrease
  • SOFA
    Can be used as a quick screening tool when time, resources, and available assessment data don't allow for a full SOFA calculation
  • Sequential Organ Failure Assessment (SOFA)
    • Sepsis-relates
    • Organ
    • Failure
    • Assessment
  • SOFA criteria
    • Alerted mental status
    • Fast respiratory rate
    • Low Blood Pressure
  • If a client scores 2 or more on SOFA (criteria suggests a greater risk of poor outcome)
  • Septic shock
    A subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with greater risk of morality than with sepsis alone
  • Septic shock criteria
    • Need vasopressors to maintain MAP of 65mmhg
    • Lactate >2mmol/L in the absence of hypovolemia
  • Mortality of septic shock is 40%
  • Patient presentation when starting to go into septic shock
    • Altered mental status
    • Hypotension
    • Oliguria or anuria
  • If treated well, patient will express better condition
  • If not treated well, patient will go into septic shock and multiple organ dysfunction syndrome
  • S&S to remember when caring for pts with confirmed infection or high risk of infection
    • Hypotension
    • Tachycardia
    • Tachypnea, hypoxia
    • Decreased LOC and/or restlessness/ confusion
    • Hypo or hyperthermia (warm and flushed early on and cool/clammy later)
  • Infections almost always cause inflammation, but not all inflammation is caused by infections
  • Not all infections progress to sepsis or septic shock
  • If a patient is neutropenic, they may not respond to infection with inflammation
  • Those who are immune compromised, elderly or have multiple co-morbidities are more prone to infection
  • Most common bacteria causing infections
    • e-coli
    • streptococci
    • staphylococci
  • Systemic Inflammatory Response Syndrome (SIRS)
    An exaggerated stress response to a noxious stressor such as trauma, surgery & infection
  • SIRS Criteria
    • Heart rate greater than 90 bpm
    • Respiratory rate greater than 20 rpm
    • Temperature greater or equal to 38.0°C or less than 36.0°C
    • Altered mental state
    • WBC greater than 12.0 or less than 4.0 x 10 /L
  • Sepsis
    When the exaggerated inflammatory response causes organ dysfunction
  • Sepsis Pathophysiology
    1. Nursing Assessments
    2. Neurological
    3. Cardiovascular
    4. Respiratory
    5. Gastrointestinal
    6. Renal
    7. Skin
  • Nursing Assessment Priorities
    • VS q1-2H to watch for hypotension, tachycardia, tachypnea, hypoxia
    • Chest assessment q1-2h to watch for subtle changes, pleural effusion and difficulty ventilating
    • Neuro status - increasingly drowsy? Confused? Restless?
    • Peripheral perfusion - cool, mottled lower limbs/knees is a sign of septic shock, perfuse edema
    • Urine output q1h via urometer to assess kidney function and fluid volume status
    • Bloodwork and microbiology results
  • Septic Shock
    A subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone
  • Septic Shock Criteria
    • Need Vasopressors to maintain a MAP of 65mmhg
    • Lactate > 2mmol/L in the absence of hypovolemia
  • Mortality of septic shock is 40%
