Initial Resuscitation and Shock
Recognise critical illness and lead a structured resuscitation while identifying shock mechanism.
How to prepare for MRCEM SBA
Build clinical synthesis across stable adult care, resuscitation, injury, paediatrics, procedures and complex decisions while preserving the full RCEM clinical-syllabus breadth.
Core concepts
Concept 1
ABCDE assessment, monitoring, vascular access, fluids and blood, vasoactive support, obstructive, distributive, hypovolaemic and cardiogenic shock.
Exam cue: Identify diagnosis, investigation, immediate treatment, longer management, disposition or professional action in the lead-in.
Concept 2
Treat immediate threats, use response and bedside data to refine shock type, and escalate definitive care without delay.
Exam cue: Use acuity, age, physiology, time course, comorbidity and response to treatment to rank plausible options.
Concept 3
Reassess after every intervention and recognise occult shock, fluid harm and need for source control or advanced support.
Exam cue: Choose the single fully correct action at this point in care and know when senior, specialty or critical-care escalation is required.
Concept 4
Use the current Year 1-3 RCEM capabilities and the full clinical syllabus at the understanding-and-applying level expected before higher specialist training.
Risk pitfalls and guardrails
Waiting for diagnostic certainty before treating time-critical physiology or repeatedly giving fluid without reassessment.
Guardrail: Do not delay stabilisation, haemorrhage control, antimicrobials or escalation for a test that will not change immediate care.
Choosing a true statement that does not answer the exact time point or clinical task.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Inventing a paper-specific or subcategory weighting that RCEM has not published.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Memory anchors
Initial Resuscitation and Shock: scope
ABCDE assessment, monitoring, vascular access, fluids and blood, vasoactive support, obstructive, distributive, hypovolaemic and cardiogenic shock.
Initial Resuscitation and Shock: clinical synthesis
Treat immediate threats, use response and bedside data to refine shock type, and escalate definitive care without delay.
Initial Resuscitation and Shock: safety boundary
Reassess after every intervention and recognise occult shock, fluid harm and need for source control or advanced support.
Initial Resuscitation and Shock: common trap
Waiting for diagnostic certainty before treating time-critical physiology or repeatedly giving fluid without reassessment.
Initial Resuscitation and Shock: MRCEM SBA sequence
Identify the clinical task and acuity, synthesise history, examination and investigations, choose the safest evidence-based decision, then check disposition and escalation.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A man rescued from a house fire has facial burns, soot in the mouth, progressive hoarseness and stridor. Oxygen saturation is 96% on high-flow oxygen. What is the priority?
A 45-year-old woman with pyelonephritis is warm peripherally, tachycardic and hypotensive with bounding pulses and a wide pulse pressure. Which shock pattern is most likely?
