Day 2 of Pneumonia: Recognising Septic Shock on a Ward With No HDU Bed
Mr Otieno, 62 years old, 74 kg, was admitted 36 hours ago with community-acquired pneumonia. He has type 2 diabetes and hypertension. He is on IV ceftriaxone 2 g daily and oxygen 2 L/min by nasal prongs. At 06:00 he was fully oriented, respiratory rate 22, SpO2 94%, temperature 37.8 °C. At 14:00 the handover nurse finds him drowsy but rousable, answering in single words. Respiratory rate 30 and shallow, SpO2 88% on 2 L, pulse 122 and irregular, blood pressure 92/56 mmHg (admission baseline 138/82), temperature 38.9 °C, capillary refill 4 seconds. The catheter has drained 20 mL in four hours. Capillary glucose is 14.2 mmol/L. The laboratory phones a lactate of 4.1 mmol/L. The ward has no high-dependency bed. The medical officer is in theatre and the covering clinical officer is 20 minutes away by road.
1. Which findings form the priority pattern, what is your working interpretation, and how would you state it in one sentence to the clinician?

Pattern. Three findings form a recognised deterioration signature: respiratory rate 30 (≥22), systolic BP 92 mmHg (≤100) and new altered mentation - a qSOFA of 3/3. Add lactate 4.1 mmol/L, capillary refill 4 seconds, urine output of 5 mL/hour and glucose 14.2 mmol/L, and this is not simply 'pneumonia with a temperature'. It is sepsis with hypoperfusion - septic shock - with the lung as the probable source.
Why the label matters. The BP of 92/56 would not trip a 'low BP' alarm on many observation charts, yet it is well below his own baseline of 138/82. The drowsiness and the oliguria are organ-dysfunction markers, not comfort issues. The irregular pulse at 122 also needs a 12-lead ECG, because fast atrial fibrillation can be contributing to the hypotension.
SBAR sentence. 'Mr Otieno, 62, day two of pneumonia, has become drowsy with RR 30, SpO2 88% on 2 litres, BP 92/56 against a baseline of 138/82, 20 mL of urine in four hours and a lactate of 4.1 - I think he is in septic shock and I need you at the bedside now.'
Naming the syndrome and its trajectory is what buys a response. Reading out six observations without a conclusion usually gets 'keep monitoring'.
2. List, in order, the first six actions you would take in the next 30 minutes and justify the sequence.

- Sit him up as tolerated and increase oxygen to a reservoir mask, targeting SpO2 94–98%, with continuous oximetry. Hypoxaemia kills before the antibiotics are due; this is the only intervention that cannot wait for a colleague.
- Call for help and escalate: activate the rapid-response or on-call clinical officer, ask the in-charge to clear a monitored bed or prepare for transfer. Do this while still at the bedside.
- Two large-bore cannulae; take blood cultures (two sets) plus FBC, urea and electrolytes, glucose and clotting. Cultures must not delay antibiotics by more than about 45 minutes; if venepuncture is difficult, treat first.
- Fluid resuscitation: 30 mL/kg balanced crystalloid = about 2,220 mL for 74 kg, given as 500 mL boluses with reassessment of BP, pulse, capillary refill and lung bases after each. Do not run the whole volume in without reassessment if crackles appear.
- Antibiotics within one hour, escalated from ceftriaxone according to the local protocol as prescribed - cultures taken, not awaited.
- Hourly urine measurement, glucose control, temperature and cardiac monitoring, and contemporaneous documentation with times.
Sequence logic: airway and oxygenation first, then reversible circulating volume and the time-dependent antimicrobial, with diagnostics slotted in only where they do not cause delay.
3. The clinical officer says by phone: "Give the ceftriaxone and call me if he gets worse." How do you respond, and what do you do if the answer does not change?

Respond with a specific request, not a complaint. Restate the trajectory in one breath - lactate 4.1, qSOFA 3/3, urine 20 mL in four hours - then ask for named orders: a fluid bolus with a target, escalation of antibiotics, and a senior review or transfer. Ask directly, 'Are you able to come now, or should I activate the transfer pathway?' A vague 'he needs reviewing' is easy to defer; a decision request is not.
Use the system. If the answer is still 'wait', work the chain in order: the medical officer in theatre, then the nursing officer in charge, then the on-call manager or duty doctor for the facility. Where the facility has standing emergency protocols (oxygen, fluid bolus, sepsis bundle), follow them within your scope and record that you did. You are not prescribing; you are initiating an approved emergency pathway and escalating a deteriorating patient.
Document contemporaneously: observations with times, the interpretation given, who was contacted, what was advised, what you did, and the response. Documentation is both clinical and protective.
Do not accept a plan that leaves a lactate of 4.1 and 5 mL/hour of urine unaddressed, and do not soften the message to keep the peace. The risk of being thought troublesome is smaller than the risk of a preventable arrest.
