The Septic Patient Who Is 'Not That Sick'
A 58-year-old man presents at 14:00 with 3 days of fever, cough, and increasing breathlessness. He has type 2 diabetes and is on metformin. On arrival: HR 112, BP 102/64, RR 24, SpO2 93% on room air, temperature 38.6°C, GCS 15. He looks well-perfused and is chatting. His lactate is 3.8 mmol/L. Chest X-ray shows right lower lobe consolidation. The ED is holding 14 patients awaiting beds; the medical registrar says the ward is full and asks you to 'keep him in the department for a few hours and reassess'. A bed may become available on the respiratory ward in 6 hours.
1. Does this patient meet criteria for early aggressive resuscitation and senior review? Justify using the physiology and the available scoring tools.
Read the worked answer
Yes - this patient has sepsis with organ dysfunction and should be treated as time-critical.
Physiology:
- Lactate 3.8 mmol/L indicates tissue hypoperfusion. A lactate above 2 mmol/L in the setting of suspected infection is associated with increased mortality; above 4 mmol/L is a recognised high-risk threshold. This patient is approaching it.
- HR 112, RR 24, BP 102/64 - a NEWS2 or qSOFA-type assessment would score him as at least moderate risk. The systolic BP is borderline; a fall of even 10 mmHg would meet hypotension criteria.
- SpO2 93% on room air with pneumonia indicates significant gas-exchange impairment.
- Diabetes is a comorbidity that increases the risk of rapid deterioration and atypical presentation.
Why 'looking well' is misleading: Compensated sepsis can look deceptively stable until the patient crashes. The absence of hypotension now does not mean the patient is safe; it means the compensatory reserve is being used.
Conclusion: This patient needs the sepsis bundle - blood cultures, broad-spectrum antibiotics within 1 hour, fluid resuscitation, serial lactate, and senior (consultant-level) review. Holding him in the ED for 6 hours without a clear escalation plan is unsafe.
2. The medical registrar insists the ward is full. What is your escalation pathway, and how do you prioritise the actions in the first hour?
Read the worked answer
First-hour priorities (in order):
- Antibiotics - do not wait for the ward. Obtain cultures if this does not delay antibiotics, then give broad-spectrum cover for community-acquired pneumonia within 1 hour.
- Fluids - 30 mL/kg crystalloid for sepsis-induced hypoperfusion, reassessing response (BP, lactate, capillary refill) after each bolus. Be cautious if there is any evidence of cardiac dysfunction.
- Senior review - call the on-call medical consultant or the ED consultant. A lactate of 3.8 with pneumonia is a consultant-level decision.
- Serial observations and lactate - repeat lactate within 2–4 hours; a rising lactate despite fluids mandates escalation.
- Oxygen - titrate to a target saturation (94–98% for most patients; 88–92% if COPD is confirmed).
Escalation pathway:
- Ask the medical registrar to document the refusal and the reason in the notes.
- Escalate to the on-call medical consultant, then the site manager or bed manager.
- If the patient deteriorates, activate the rapid response or MET call.
- Consider a higher level of care (HDU/ICU) if he remains hypoperfused after fluids - that is a clinical decision, not a bed decision.
Documentation: Record the time of each intervention, the escalation calls, and the responses. The key principle is that bed pressure does not change the clinical priority; the patient's physiology does.
