and potential future changes in sepsis care
5. A. Under-recognized
B. Under-treated
C. Misunderstood (pathophysiology)
D. All of the above
Sepsis 3?
13. 1. Figure it out EARLY Sepsis Screening
2. Fill theTank = Fluids IVC US, Dynamic
measures, PLR
3. Fight the Bugs Antibiotics
Source Control
4. Fix perfusion MAP Organ fx
Lactate Inotropes
The 4 F’s
14. Institution-Wide Multidisciplinary Approach
Sepsis Screening/Early recognition protocol
(Automated)
Early Management Bundle/Order set
Continued Care Bundle
Education + Re-education = Culture of change
Chart dives
Be Data-driven
18. 1. Use Cardiac
Probe
2. Place probe in
the long axis,
SubX, just right
of midline
3. Find IVC and
measure 3 cm
distal to RA (at
or distal to HV)
4. Can use M-
mode
5. Have patient
sniff if
spontaneously
breathing
19. IVC < 1 cm = give fluids
IVC 1-2 cm w/ 50% collapse w/ inspiration=
give fluids
IVC > 2 cm or w/o collapse = not fluid
responsive
Pulmonary Hypertension/RHF may confound
your IVC US
Patients on mechanical ventilation – look for
a 15-18% change in IVC diameter
22. ICU population
Vasopressor dependent septic shock
All on mechanical ventilation
Limited Echo (LE) performed w/in 24 hours of
ICU admission
23. 1. Systolic function:
normal, moderate, or
severely impaired
2. Assess for pericardial
effusion
3. IVC diameter
fluctuation < or > 15%
dIVC=[(dI−dE)/dE]×100
<15% dIVC with normal LV fx = stop
fluids
>15% dIVC w/ normal LV fx = 20 to 40
mL/kg fluids
>15% dIVC w/ mod to severe LV
dysfx = 10 to 20 mL/kg fluids and
dobutamine 5 mcg/kg
<15% dIVC w/ mod to severe LV
dysfx = dobutamine and no fluids
24. Passive leg raise.To perform a passive leg raise, a patient is
placed in a semi-recumbent position at 45°.The patient’s legs
are then elevated to 45° and the hemodynamic variable of
interest evaluated after 30−60 seconds.
25. 1. Is fluid resuscitation adequate?
- Heart, IVC collapse, PPV, SVV
2. Is MAP adequate?
- MAP > 65
3. Is Oxygen Delivery adequate?
- Lactate normalization vs Lactate clearance?
Now Go Back and Ask 3 Questions…
What about individual measures of organ function?
27. Effective Abx within 1st hour for sepsis and
septic shock (2016)
Every hour of delay in giving Abx is associated
with a measurable increase in mortality
(Kumar et al; Ferrer et al)
Mortality significantly increased in patients
who received initial antibiotics after shock
recognition (n = 172 [59%]) compared with
before shock recognition (OR, 2.4; 1.1-4.5) –
Puskarich et al
28. Gram + > Gram - > polymicrobial as the cause
of most septic shock
Bolus drugs before infusion drugs
Broad coverage guided by local prevalence
patterns
All patients should receive a full loading dose
of antibiotics
29. EmpiricTherapy – best guess, no bugs yet
Broad SpectrumTherapy – broad spec abx to
cover multiple potential bugs
CombinationTherapy – Using more than one
drug to cover the same bug (largely
unproven)
30. Empiric combo therapy for initial
management of septic shock
No Empiric combo therapy for regular sepsis
or bacteremia
No combo therapy for neutropenic
sepsis/bacteremia
If combo therapy is used – de-escalate in the
first few days if clinical improvement
31. “Trauma is a compulsive search for injuries” –
Billy Mallon
“Sepsis is a compulsive search for a source of
infection” – Me
Treat the patient like a trauma – fully expose, etc
The less the patient can tell you the more
compulsive the search
And…the severity of the source should be
proportional to the severity of illness
32. Source control as soon as possible (Rec 6-12
hrs from time of diagnosis)
If intravascular device is a possible source, it
should be promptly removed after other
vascular access established
Consider IR or Surgery
33. Cultures of blood and other sites (urine, CSF,
wounds, respiratory secretions, etc) before
abx if possible
Cultures from vascular access and peripheral
blood – 10 cc each
If culture from vascular access is positive
earlier than peripheral blood then vascular
access = infectious source
34. DO NOT DELAY ANTIBIOTICS > 45 MIN
FOR BLOOD CULTURES
38. Published in CCM in 2015
Dopamine still a bad choice for SSh
Greater hospital mortality – propensity-
matched scoring, n = 38,788; 25% vs 23.7%;
OR 1.08; 95% CI, 1.02-1.14)
Most commonly used in the South!
39. Norepinephrine 1st agent
Vaso or Epi as 2nd agent
Epi - especially if inotropy required
Vaso – need alpha
Phenylephrine if inotropy not needed
Norepi causing arrhythmias
CO is high and BP is low
Salvage therapy
Dobutamine – first choice inotrope
40. Vaso +/- HC vs Norepi +/- HC for vasopressor
dependent septic shock
Primary outcome – renal failure free days
No difference
Demonstrated thatVaso could be titrated up
to a dose of .06units/min
48. SEPSIS RECIDIVISM
110 ED patients w/ SS/SSh
28-90 days: 17% rate of
sepsis readmission
LONG-TERM MORTALITY
Initial mortality 18% (90
survivors)
3 year mortality 48% (only
53 survivors)
Chronic Critical Illness
Disease of the elderly who survive initial sepsis dc LTAC, functionally dependent,
die outside of the hospital months to years later (Sepsis P50 – UF)
52. Old definitions
SEVERE SEPSIS: SIRS + sepsis-induced organ dysfunction:
SBP < 90 or MAP < 70 mm Hg
Creatinine > 2.0 mg/dl or Urine Output < 0.5 ml/kg/hour for > 2
hours
Bilirubin > 2 mg/dl (34.2 mmol/L)
Platelet count < 100,000
Coagulopathy (INR >1.5 or aPTT >60 secs)
Lactate > 2 mmol/L
SEPTIC SHOCK:
Lactate > 4 mmol/L, OR
SBP < 90 or MAP < 70 mm Hg, not responsive to fluids
53. A. measure lactate level
B. obtain blood cultures prior to antibiotics
C. administer broad spectrum antibiotics
D. administer 30 ml/kg crystalloid for hypotension or
lactate = 4 mmol/L
E. apply vasopressors (for hypotension that does not
respond to initial fluid resuscitation to maintain a
mean arterial pressure = 65)
F. in the event of persistent hypotension after initial
fluid administration (MAP < 65 mm Hg) or if initial
lactate was = 4 mmol/L, reassess volume status and
tissue perfusion and document findings.*
54. 2/4 of the following
Measure CVP
Measure ScvO2
Bedside cardiovascular ultrasound
Dynamic assessment of fluid responsiveness with
passive leg raise or fluid challenge
OR Focused exam† including vital signs,
cardiopulmonary, capillary refill, pulse and skin
findings.
Remeasure lactate if initial lactate is elevated
55. But sadly, it’s the end of my lecture
Thank you!
59. Fluids - 30 ml/kg in the first 3 hours, crystalloid first, then maybe
albumin, use dynamic markers and/or fluid challenges
Goal MAP>65
EGDT is no longer recommended
Lactate - attempt to normalize lactate
Blood Cultures - get them before antibiotics, if obtaining them will
not delay the provision of antibiotics
Antibiotics -Within 1 hour of sepsis or septic shock
Vasopressors - Norepi is the first choice, add in epi or vaso, Do not
use dopamine
Steroids - 200 mg Hydrocortisone for patients who are still
unstable after fluids and vasopressors
Blood - In most circumstances, use a trigger of <7.0 g/dL
Glucose - goal is < 180 mg/dL
Bicarb - Not recommended if pH is >7.15 (which in no way means it
is recommended for pHs less than that)
Notas del editor
THE PERFECT STORM THAT TORE THROUGH GEORGIA ON MY FLIGHT TO LOS ANGELES
Wall of storms that spun off tornadoes
Complicated disease – sepsis for which there are no biomarkers or gold standard tests
biological concepts that are currently incompletely understood, such as genetic influences and cellular abnormalities, comorbidities
- No troponin like a heart attack
- can’t be diagnosed with a CT scan
- Lactate can’t tell you whether or not to think someone is septic, only how sick they are after you recognize the sepsis
Involve CMS regulations – word for word interpretation of the definitions, mandate how patients with suspected sepsis are to be cared for
Change the definitions for this complicated disease
Conceptual Framework for sepsis
Infection + Organ dysfunction
OLD – Sepsis and infection were almost one and the same
NEW – Sepsis is very distinct from most infections
MY OPINION -
Cellulitis – could be localized, no systemic signs
Pneumonia – may have systemic signs, fever, tachycardia, etc
Sepsis – confusion, oliguria, mottling, thrombocytopenia, hypoxia
Shock - – MAP < 65 (not responsive to fluids), vasopressors, lactate > 2
Dangerous as a screening tool - Rule in for high risk sepsis
38% sensitive, 85% specific for death
Use it – but understand the limitations
Positive = move to resus bay, jump on this patient
Neg = keep looking
Robust scoring system – very well –studied
Look for new changes in SOFA components
Accurate prognosis for death
associated with need for intensive care
Associated with long-term organ dysfunction and poor outcomes as well as sepsis recidivism
NOT USER FRIENDLY – EPIC AUTO CALCULATOR?
First 10 decisions you make in a critically ill, un-resuscitated patient are critical determinants of life or death
Intubate
Give blood in a trauma (OR when to go to the OR)
Manage a head injury – avoid hypoxia or hypotension
When to start antibiotics in sepsis, how much fluids you give and how quickly
What tests to order – lytes on a blood gas in a patient with bradycardia for HyperK
US-Guided Decision making – FAST, Echo, RUSH exam, Lung US
Basic Rules for managing sepsis
Negative pressure created by the inspiration of the patient increases venous return to the heart, briefly collapsing the IVC.
Improved 28 day survival
Reduced rates of AKI
Changed from 3 hrs for sepsis, 1 hr for shock in 2012 guidelines
Modern abx are more effective – no benefit in neutropenic fever/sepsis without shock
Balance risk benefit – for shock, benefit > risk
For non-shock sepsis – Risk of AKI, etc prob > benefit
Foci of infection readily amenable to source control - intra-abdominal
abscesses, gastrointestinal perforation, ischemic bowel
or volvulus, cholangitis, cholecystitis, pyelonephritis associated
with obstruction or abscess, necrotizing soft tissue
infection, other deep space infection (e.g., empyema or
septic arthritis), and implanted device infections.
Lines in for greater than 48 hours (if suspected source should be pulled as quickly as possible
Septic patients treated with Dopamine had increased risk of death in observational studies (relative risk 1.23, p<0.01) and randomized trials (relative risk 1.12, p<0.035)
Increased risk of arrhythmias with Dopamine (relative risk 2.34, p< 0.001) – Debacker et al
Dobutamine is not a pressor! It’s an inotrope! But Epi is prob a better choice
Arterial line as soon as possible
Remember –
Epi can be bad for splanchnic circulation and increases lactate and may preclude lactate normalization as a resuscitation endpoint (stimulates skeletal muscle B2 receptors)
Vaso at higher doses cardiac, digital, and splanchnic ischemia
Picking an arbitrary clearance target not as good though there is some evidence
Increases in the serum lactate level may represent
tissue hypoxia, accelerated aerobic glycolysis driven
by excess beta-adrenergic stimulation, or other causes
(e.g., liver failure). Regardless of the source, increased
lactate levels are associated with worse outcomes [32].
TRISS trial
1. Rushing to intubate the under-resuscitated patients or overdosing RSI meds2. ignoring high lactates or not rechecking high lactates? Could talk about the controversy behind where lactate comes from3. Not enough fluids, or too much? 4. Passing off AMS5. Missing subtle signs of organ dysfunction 6. Post-shock vs pre-shock abx, same as hourly delay in abx7. Not following resuscitative end points - 3 windows to the world, improvements in mental status, increased urine output, IVC US, echo
This will become an issue!
- sore throat/fever, 10 wks pregnant
- workup negative except abnormal labs, admitted, decompensate to ARDS/shock
- undiagnosed autoimmune disease resulting in diffuse alveolar hemorrhage, cause of miscar.
