- Patent. Nil airway obstructions. Nil stridor or gurgling. Patient able to maintain own airway.
- Breathing
- Adequate. RR 16, no increased work of breathing, nil audible adventitious sounds.
- Circulation
- Radial pulse present — rapid and weak. Skin pale, cool and diaphoretic. Nil visible bleeding.
- Disability
- GCS 13 (E3V4M6). Not orientated to time or place. Confused and slow to respond. Blood glucose level 2.1 mmol/L.
- Exposure
- No rashes, wounds or injuries visible. Patient dressed in light clothing appropriate for warm conditions.
Vitals
| Time | SpO2 | Resp Dist | RR | Pulse | BP | CRT | GCS | PERL | Temp | BGL | Pain |
|---|---|---|---|---|---|---|---|---|---|---|---|

- Medications
- Metformin 500mg twice daily. Gliclazide 80mg once daily. Perindopril 5mg once daily.
- Pertinent History
- Known Type 2 diabetes mellitus for 12 years. Hypertension. No previous hypoglycaemic episodes requiring outside assistance.
- Last Oral Intake
- Breakfast approximately 5 hours ago — toast and tea. Has not eaten since. Has been walking around the fair for approximately 2 hours.
- Events Leading
- Patient attending Mandurah Community Fair with his wife who went to use the amenities. Bystanders found him sitting on a bench looking pale and confused.
- Treatment Prior
- Nil. Bystander gave patient a bottle of water but no food or glucose.
- Onset
- Gradual onset over approximately 15–20 minutes while walking around the fairground.
- Pain
- Nil pain reported.

- Weakness and trembling in both hands. Feels lightheaded.
- Radiates
- Nil
- Severity
- N/A — no pain. Confusion rated by bystander as significantly worse than normal.
Treatment Response
Diagnosis
This patient is suffering from hypoglycaemia secondary to sulphonylurea medication use (gliclazide) and missed meal in a 75-year-old male with known Type 2 diabetes mellitus.
Facilitator Triggers — if trainees miss a critical step
- ! (If BGL is not checked within the first 2 minutes, the patient's GCS drops to 11 — he becomes increasingly drowsy and stops responding to questions coherently.)
- ! (If Glucose Oral Gel is not administered within 5 minutes of BGL result, patient becomes more diaphoretic and GCS drops to 10 — facilitator states patient is no longer able to safely swallow oral glucose gel.)
- ! (If trainees do not reassess BGL 10 minutes after glucose administration, inform them the patient is asking 'where am I?' and appearing more alert — prompt them to recheck BGL to confirm response to treatment.)
- ! (If trainees do not offer complex carbohydrates following BGL recovery, prompt by having patient say 'I'm feeling better but still a bit wobbly — should I eat something?')
Treatment Objectives
- 1 Don PPE and approach scene safely — confirm scene safety at community fair.
- 2 Perform Primary Survey — assess DRSABCD.
- 3 Confirm patient response level — responds to voice, GCS 13.
- 4 Assess airway — patent, self-maintaining.
- 5 Assess breathing — adequate, RR 16, SpO2 96% on room air. Apply oxygen only if SpO2 falls below 94%.
- 6 Assess circulation — rapid weak pulse, pale diaphoretic skin, CRT 3 seconds.
- 7 Perform Blood Glucose Level (BGL) measurement — result 2.1 mmol/L, confirming hypoglycaemia.
- 8 Perform Vital Sign Survey — record HR, RR, BP, SpO2, GCS, BGL, temperature.
- 9 Confirm GCS is 15/15 prior to oral glucose administration — GCS 13, patient is NOT 15/15. Do NOT give oral food or gel unsupported without reassessment.
- 10 Re-assess patient capacity to safely ingest oral glucose — at GCS 13 patient is drowsy but able to follow commands and swallow. Administer Glucose Oral Gel 15g (entire tube) into buccal mucosa in small amounts, monitoring for aspiration risk.
- 11 Position patient seated and supported — do not allow patient to stand or walk. Keep patient at rest on bench with support.
- 12 Reassess GCS and BGL at 10 minutes post glucose gel administration.
- 13 At 10 minutes: BGL 5.8 mmol/L, GCS 15 — confirm patient is alert and oriented.
- 14 Provide complex carbohydrates following BGL recovery (e.g. biscuits, sandwich) to prevent delayed hypoglycaemia.
- 15 Advise patient not to stand or mobilise until fully assessed and BGL stable.
- 16 Contact patient's wife (Margaret Hennessey, 0412 883 047) to attend FAP.
- 17 Arrange ambulance transport — gliclazide (sulphonylurea) poses risk of recurrent hypoglycaemia and patient requires hospital assessment.
- 18 Document all vital signs, BGL readings, treatment administered and patient response on patient care record.
- 19 Scenario ends on arrival of ambulance and IMISTAMBO handover.
- 20 Attention to hand hygiene will be given throughout the scenario.
