Time is life in sepsis. Every hour of delay in antibiotics increases mortality by ~7%. The 1-hour bundle (lactate, blood cultures, antibiotics, fluids) is not a suggestion — it's the standard of care. Start the clock the moment sepsis is suspected.
Definitions (Sepsis-3, 2016)
| Term | Definition | Clinical Criteria |
|---|
| SIRS (historical) | Systemic inflammatory response (no longer defines sepsis) | 2+ of: temp >38°C or <36°C, HR >90, RR >20, WBC >12K or <4K |
| Sepsis | Life-threatening organ dysfunction caused by dysregulated host response to infection | SOFA score increase ≥2 points from baseline in suspected infection |
| Quick SOFA (qSOFA) | Bedside screening tool (2 of 3 = high risk for sepsis) | RR ≥22, altered mentation, SBP ≤100 |
| Septic shock | Sepsis + circulatory and cellular/metabolic abnormalities | MAP <65 mmHg despite fluid resuscitation + lactate >2 mmol/L requiring vasopressors |
qSOFA at the bedside: Score 1 point each for RR ≥22, new confusion/AMS, SBP ≤100. Score ≥2 = call the provider NOW. Does NOT diagnose sepsis; flags who needs urgent assessment.
Early Recognition
Classic Sepsis Signs (not always present together)
- Fever (>38.3°C) OR hypothermia (<36°C) — hypothermia is an ominous sign
- Tachycardia (HR >90 bpm)
- Tachypnea (RR >20 or PaCO2 <32)
- Altered mental status — confusion, agitation, lethargy
- Warm, flushed skin in early sepsis (vasodilation); cold, mottled, clammy in late sepsis
- Hypotension (late and dangerous sign — don't wait for it)
- Decreased urine output (<0.5 mL/kg/hr)
Common Sources of Infection (LUNCHBOX Mnemonic)
- Lung — pneumonia (most common)
- Urinary — UTI, pyelonephritis (especially in elderly)
- Necrotizing fasciitis
- Catheter / line-related bloodstream infection
- Hepatic / biliary — cholangitis, cholecystitis
- Bowel — perforation, diverticulitis, C. diff colitis
- Osteomyelitis / joint infection
- X (skin) — cellulitis, wound infection
Surviving Sepsis Campaign: 1-Hour Bundle
Complete ALL 5 actions within 1 hour of recognizing sepsis or septic shock. Time zero = time of triage or first documentation of clinical criteria.
| # | Action | Nursing Role |
|---|
| 1 | Measure lactate level | Draw STAT; repeat if initial >2 mmol/L; serial lactates guide resuscitation; lactate >4 = high mortality |
| 2 | Blood cultures before antibiotics | Two sets (two different sites) before first antibiotic dose; don't delay antibiotics more than 45 min to get cultures |
| 3 | Broad-spectrum antibiotics | Administer within 1 hour of recognition; confirm allergy history; document time given; de-escalate after culture results |
| 4 | 30 mL/kg crystalloid for hypotension or lactate ≥4 | Run in NS or LR wide open; reassess after each 500 mL bolus; watch for signs of fluid overload (rales, SpO2 drop); document total I&O |
| 5 | Vasopressors if MAP <65 after fluid resuscitation | Norepinephrine via central line preferred; arterial line for continuous BP monitoring; titrate to MAP ≥65; document infusion rate |
Fluid Resuscitation
Crystalloid Choice
- Normal saline (0.9% NaCl) or Lactated Ringer's — both acceptable first-line
- Balanced crystalloids (LR, Plasma-Lyte) preferred by many centers — less hyperchloremic acidosis risk
- Albumin (25%) may be considered when substantial volumes of crystalloid already given — not routine first-line
- AVOID: hetastarch (HES) — increases AKI and mortality
Assessing Fluid Responsiveness
- Passive leg raise (PLR): Raise legs 45° for 1 minute; if CO increases ≥10%, patient is fluid responsive; a dynamic, reversible way to test before giving more fluid
- Pulse pressure variation (PPV): >13% on mechanical ventilation = fluid responsive
- Point-of-care ultrasound (POCUS): Bedside IVC assessment — collapsible IVC = hypovolemia; flat IVC = severe volume depletion
- Lactate clearance: Target ≥10% decrease in lactate every 2 hours — lactate still elevated despite fluids = inadequate resuscitation OR tissue isn't improving
Fluid overload kills too. ARDS, pulmonary edema, and abdominal compartment syndrome are complications of overly aggressive fluid resuscitation. The goal is "resuscitate, then restrict" — not endless fluid boluses.
Vasopressors in Septic Shock
| Drug | Mechanism | First-Line? | Key Points |
|---|
| Norepinephrine (Levophed) | Alpha > beta; vasoconstriction + mild inotrope | YES — first-line for septic shock | Requires central line; titrate to MAP ≥65; "Leave 'em dead" (vasodilatory shock drug of choice) |
| Vasopressin (Pitressin) | V1 receptor; potent vasoconstriction; non-catecholamine | Add-on to norepinephrine | Add when NE dose >0.25 mcg/kg/min; reduces catecholamine requirements; does NOT increase HR; fixed dose (0.03 units/min) |
| Epinephrine | Alpha + beta agonist | Add-on or anaphylaxis | Increases HR and BP; increases lactate (may confound monitoring); reserved for refractory shock |
| Dopamine | Dose-dependent (dopaminergic/beta/alpha) | Limited role; alternative if NE unavailable | Higher arrhythmia risk than NE; no longer first-line for septic shock |
| Phenylephrine | Pure alpha agonist | NOT preferred for septic shock | Decreases CO (reflex bradycardia); may be used if tachyarrhythmia limits NE |
| Dobutamine | Beta-1 inotrope | Add for low cardiac output | Does NOT treat hypotension alone; add when cardiac dysfunction/low CI persists after fluids and NE; may cause hypotension |
Steroid pearl: Hydrocortisone 200 mg/day (50 mg IV q6h or 200 mg continuous) if refractory septic shock (MAP <65 despite NE ≥0.25 mcg/kg/min AND adequate fluids). Not for all sepsis patients — only refractory shock.
Nursing Monitoring Priorities
| Parameter | Goal | Frequency |
|---|
| MAP | ≥65 mmHg (higher in chronic HTN, trauma) | Continuous via arterial line; q15 min if cuff only |
| Urine output | ≥0.5 mL/kg/hr; AKI common in septic shock | Hourly via Foley |
| Lactate | Downtrend to <2 mmol/L; ≥10% clearance per 2 hr | q2–4 hours until normalized |
| Temperature | Treat fever with acetaminophen; avoid cooling blankets in sepsis | q1–4 hours |
| Mentation / GCS | Improving alertness = improving perfusion | Hourly in ICU |
| Skin | Capillary refill <3 sec; resolution of mottling | Hourly |
| I&O | Document all fluid in/out; running total | Hourly |
| Vasopressor dose | Titrate NE to MAP ≥65; wean as tolerated when MAP stabilizes | Continuous documentation |
NCLEX High-Yield Points
- Septic shock = sepsis + MAP <65 despite fluids + lactate >2 mmol/L requiring vasopressors
- 1-Hour bundle: lactate → blood cultures → antibiotics → 30 mL/kg crystalloid → vasopressors if needed
- Blood cultures BEFORE antibiotics — but don't delay antibiotics more than 45 min waiting for cultures
- First-line vasopressor = norepinephrine (Levophed); requires central line
- Lactate >4 = severe sepsis; serial lactate monitoring tracks response to treatment
- Passive leg raise tests fluid responsiveness without committing to a fluid bolus
- Early sepsis: warm, flushed, bounding; late sepsis: cold, mottled, clammy = distributive shock converting to multiorgan failure
- Hydrocortisone: only for REFRACTORY septic shock (NE ≥0.25 mcg/kg/min + still MAP <65)
