Sepsis Nursing Care Bundle
On this page
Direct answer
Septic shock kills within hours, and the bedside nurse controls the clock: the Surviving Sepsis Campaign's Hour-1 bundle exists because every element loses value with delay. Screening comes first — qSOFA flags risk with respiratory rate 22 or more, altered mentation and systolic pressure 100 or less — and once sepsis is recognised, the bundle runs as one movement: measure lactate (and remeasure if it is 2 mmol/L or more), draw blood cultures before antibiotics, deliver broad-spectrum antibiotics within the first hour, give 30 mL/kg of crystalloid for hypotension or lactate of 4 or more, and start vasopressors — noradrenaline first-line — to hold mean arterial pressure at 65 mmHg or above. Nursing owns the logistics of all five: access, culture bottles, timing documentation, the fluid that actually runs, and the observations showing whether lactate clears and urine flows.
What you must remember
- qSOFA: respiratory rate at least 22, altered mentation, systolic pressure 100 or less — two or more flags a high-risk patient; SIRS criteria remain the sensitive net that catches the others.
- The Hour-1 bundle: lactate measured and remeasured within 2-4 hours if at least 2 mmol/L; two blood culture sets before antibiotics; broad-spectrum antibiotics within one hour; 30 mL/kg crystalloid for hypotension or lactate 4 or more; vasopressors to MAP 65 if hypotension persists.
- Culture craft: two sets from separate sites, one from a fresh stick where possible, timed and labelled — but never delaying the antibiotic past the hour.
- Fluid reality: 30 mL/kg is roughly 1.5-2 litres in an adult, started within the hour and assessed — pulse, pressure, capillary refill, urine output — because fluid without reassessment is just oedema.
- Noradrenaline, not adrenaline: first-line vasopressor in septic shock, ideally via a central line, titrated to MAP 65 or above.
- End points that matter: lactate clearance, urine output at least 0.5 mL/kg/hour, mentation and MAP.
- Source control is nursing too: removing the culprit catheter, draining the abscess — an undrained source makes antibiotics spectators.
- Indian context: puerperal sepsis remains a reviewed cause of maternal death in India, and febrile postpartum women deserve the same bundle, the same hour, as everyone else.
The first sixty minutes of septic shock
A 58-year-old with a urinary infection arrives confused, breathing at 26, pressure 86/50. The triage nurse recognises qSOFA three of three and says the word sepsis aloud, starting clocks that otherwise never start. Minute 5: monitor on, two large-bore cannulae, lactate drawn. Minute 10: two culture sets from separate sites. Minute 20: the first antibiotic running — no waiting for a bed, because the bundle belongs to recognition time. Minute 25: 30 mL/kg crystalloid wide open, capillary refill shortening, pulse falling from 122 to 104.
By minute 55 the pressure has drifted to 82 despite a litre and a half; noradrenaline starts per protocol, titrated until the MAP reads 66. The one-hour note documents five timestamps — recognition, cultures, antibiotic, fluid, vasopressor. At hour four lactate has fallen from 4.2 to 2.4, urine runs 40 mL/hour and the confusion has cleared. Nothing heroic — five ordinary acts, none delayed.
Where the marks are lost
The classic losing answer is "transfer to intensive care and start the bundle there" — the bundle is ward work, and the transfer is what happens after it is running. The second is culturing after the antibiotic: one dose sterilises the bottle, and the susceptibility data that would later narrow therapy is gone; the correct sequencing, cultures then antibiotic, both inside the hour, is examinable in exactly that order. The third is unmeasured fluid: 30 mL/kg written but not run, or run into a failing heart without reassessment — strong answers pair every fluid order with response markers. For viva depth, know why noradrenaline: septic shock is vasoplegic, and its alpha activity restores vascular tone with fewer arrhythmias than adrenaline. And keep the obstetric addendum ready for Indian papers — puerperal sepsis.
Frequently asked questions
What are the qSOFA criteria?
Respiratory rate of 22 or more, altered mentation and systolic blood pressure of 100 or less; two or more indicate higher risk of poor outcome in suspected infection.
What are the five elements of the Hour-1 sepsis bundle?
Measure lactate, obtain blood cultures before antibiotics, give broad-spectrum antibiotics, give 30 mL/kg crystalloid for hypotension or lactate 4 mmol/L or more, and start vasopressors to keep MAP at 65 mmHg or above.
How fast should the fluid bolus be given?
Started within the hour and infused rapidly with reassessment of pressure, perfusion and urine output — with caution and smaller aliquots in cardiac or renal failure.
Why is noradrenaline the first-line vasopressor in septic shock?
Because septic shock is vasoplegic: noradrenaline's alpha activity restores vascular tone and MAP with modest beta effects and fewer arrhythmias.
Why must blood cultures precede the first antibiotic dose?
One dose can sterilise cultures and lose the organism and its susceptibility pattern, removing the chance to de-escalate — without delaying the antibiotic beyond one hour.
