Septicemia and Septic Shock

Definitions and Spectrum

Septicemia (bacteremia with systemic toxicity) refers to the presence and multiplication of bacteria in the bloodstream, producing systemic illness. All Salmonella species can cause bacteremia; infections with S. Typhi, S. Paratyphi, and S. Choleraesuis more commonly produce a bacteremic phase, with localized suppurative complications (osteomyelitis, endocarditis, arthritis) in up to 10% of cases. - Medical Microbiology 9e

Sepsis (Sepsis-3 definition, 2016): a life-threatening organ dysfunction caused by a dysregulated host response to infection. Organ dysregulation is identified as an increase in the Sequential Organ Failure Assessment (SOFA) score of ≥2 from baseline. The older SIRS-based definition (needing ≥2 of the four SIRS criteria) is now considered outdated. - Sabiston Textbook of Surgery; Washington Manual of Medical Therapeutics

SIRS Criteria (now superseded, but still referenced):

Criterion	Threshold
Temperature	>38°C or <36°C
Heart rate	>90 bpm
Respiratory rate	>20/min or PaCO2 <32 mmHg
WBC	>12,000/mm³, <4,000/mm³, or >10% bands

- Sabiston Textbook of Surgery

Septic shock is a subset of sepsis identified by persistent hypotension requiring vasopressors to maintain a mean arterial pressure (MAP) ≥65 mmHg despite adequate volume resuscitation, plus a serum lactate >2 mmol/L. Mortality is approximately 40%. - Washington Manual of Medical Therapeutics

Pathophysiology

Septic shock can result from infection with any microorganism, though no specific organism is identified in at least half of cases. Gram-negative LPS (lipopolysaccharide) is the classic driver of the inflammatory cascade, but gram-positive organisms are now the leading cause of sepsis in hospitalized patients. - Rosen's Emergency Medicine

Three primary effects occur in septic shock:

Hypovolemia - both absolute (GI loss, sweating, tachypnea, reduced intake) and relative (increased venous capacitance + capillary leak into third spaces).
Myocardial depression - direct cardiac dysfunction occurs early, driven by circulating TNF-α, IL-1β, overproduction of NO via inducible nitric oxide synthase (iNOS), and mitochondrial oxidative phosphorylation impairment. Ejection fraction falls even in the "hyperdynamic" stage.
Systemic inflammation - widespread endothelial activation, vasodilation, edema, DIC, and metabolic derangements lead to multisystem organ failure through microvascular and mitochondrial dysfunction. This produces ARDS (capillary leak in lungs), acute kidney injury, and liver dysfunction. - Rosen's Emergency Medicine; Robbins Basic Pathology

Clinical Features and Workup

Hemodynamic profile: distributive (vasodilatory) shock - high cardiac output, low SVR, warm skin early; cold, clamped periphery late.

Laboratory findings (from Rosen's Emergency Medicine):

WBC: leukocytosis (>12,000) or leukopenia (<4,000) or bandemia (≥5-10% bands) - all are imperfect indicators
Lactate: elevated; target normalization as resuscitation end-point
Procalcitonin (PCT): >0.5 ng/mL suggests bacterial infection; <0.1 ng/mL makes it less likely (but does NOT exclude severe infection)
Anion gap metabolic acidosis: often lactic acidosis; low bicarbonate indicates inadequate perfusion
Creatinine/GFR: elevated signals AKI and worsens prognosis
Coagulation panel: thrombocytopenia, elevated PT/aPTT, low fibrinogen, elevated fibrin split products/D-dimer indicate DIC
Blood cultures: obtain before antibiotics if possible, but do not delay antibiotics

Management

1. Volume Resuscitation

30 mL/kg IV crystalloid within the first hour (balanced crystalloid such as lactated Ringer preferred over normal saline - associated with lower rates of AKI and possibly improved mortality)
Albumin shows no convincing benefit over crystalloid
Hetastarch is contraindicated in septic shock
Monitor volume responsiveness to avoid overload; excessive resuscitation is associated with increased mortality
A restrictive vs. liberal fluid strategy results in similar mortality, but either requires careful monitoring - Goldman-Cecil Medicine

2. Vasopressors

First line: Norepinephrine (1-50 μg/min) - preferred over dopamine (fewer arrhythmias, particularly atrial fibrillation); acts via α1 and β1 adrenergic receptors
Second line: Vasopressin (up to 0.03 U/min) - may be added to norepinephrine when MAP target is not achieved; does not significantly outperform norepinephrine alone
Angiotensin II (20-200 ng/kg/min) can reduce early norepinephrine requirements but does not reduce mortality
Dobutamine (2-20 μg/kg/min) for patients with low cardiac index despite adequate filling pressures (low mixed venous O2 saturation with high CVP)
Target MAP ≥65 mmHg (65-70 mmHg is as effective as 80-85 mmHg as a target) - Goldman-Cecil Medicine

3. Antimicrobials

Start antibiotics immediately after blood cultures - delays in appropriate antibiotic therapy directly increase mortality
Use broad-spectrum empirical coverage based on likely source and local resistance patterns
Source control (e.g., drainage of abscess, debridement of necrotizing infection) as soon as reasonably possible - Washington Manual of Medical Therapeutics

4. Corticosteroids

Not recommended if fluid + vasopressors can restore hemodynamic stability
If refractory shock: hydrocortisone 200 mg/day IV (50 mg q6h) ± fludrocortisone (50 μg daily x7 days via NGT) may improve 90-day mortality
Hydrocortisone alone shortens duration of shock but does not reduce 90-day mortality
Risks: superinfection, neuromyopathy, hyperglycemia, immune suppression - Goldman-Cecil Medicine

5. Lactate Monitoring

Lactate clearance is associated with improved mortality; current Surviving Sepsis guidelines recommend targeting lactate normalization during resuscitation

6. Glucose Control

Hyperglycemia and insulin resistance are common
Intensive insulin therapy is NOT recommended - associated with higher hypoglycemia rates and possibly increased mortality; standard glucose control is preferred

7. Red Blood Cell Transfusion

Transfusion threshold: hemoglobin <7 g/dL (equivalent outcomes to 9-10 g/dL threshold with fewer transfusion-related complications)

8. Mechanical Ventilation / Sedation

Daily sedation interruption decreases duration of ventilation and ICU stay
Brain natriuretic peptide-guided weaning results in more ventilator-free days
Fever reduction to normothermia (36.5-37°C) via external cooling can reduce vasopressor requirements and 14-day mortality, especially with high vasopressor doses or marked tachycardia

Scoring Tools Summary

Tool	Components	Threshold for Sepsis
SOFA	Respiratory (PaO2/FiO2), Coagulation, Liver, Cardiovascular, CNS, Renal	≥2 point increase
qSOFA	Tachypnea + Altered mentation + Hypotension (SBP <100)	≥2 of 3 criteria
NEWS/MEWS	Vital signs composite	Used as screening tools

The 2021 Surviving Sepsis guidelines recommend against using qSOFA alone as a single screening tool for sepsis; SIRS, NEWS, or MEWS are preferred for initial screening. - Sabiston Textbook of Surgery

Recent Evidence (2024-2026)

A 2024 JAMA meta-analysis (PMID: 38864162) found that prolonged infusions of beta-lactam antibiotics (vs. intermittent dosing) may improve outcomes in adults with sepsis/septic shock.
A 2024 systematic review (PMID: 38904978) examined methylene blue in septic shock - a potential adjunct for refractory vasoplegic states, though evidence is still emerging.
The Surviving Sepsis Campaign 2026 Pediatric Guidelines (PMID: 41869844) have been published, updating recommendations for children.

septic shock flowchart

Image · PNG

The flowchart covers the full management pathway in 10 sequential blocks:

Block	Content
1	Recognition - qSOFA screening + SOFA criteria + Septic shock definition
2	Hour-1 Bundle - all 5 actions in parallel
3	Fluid resuscitation - balanced crystalloid 30 mL/kg
4	Vasopressor ladder - Norepinephrine → Vasopressin → Epinephrine/Ang II + Dobutamine branch
5	Antimicrobial therapy + source control alert
6	Lactate monitoring - clearance decision point
7	Corticosteroids - hydrocortisone ± fludrocortisone for refractory shock
8	Supportive care - ventilation, glucose, transfusion, renal, DVT/stress ulcer prophylaxis
9	Reassessment targets every 1-2 hours
10	ICU admission pathway

Decision diamonds branch right for YES/pass and down for NO/escalation throughout. Based on the Surviving Sepsis Campaign 2021 guidelines, Goldman-Cecil Medicine, and Washington Manual.
