Term
1. INTRODUCTION
Q: How would you start the consultation?


---



---
Definition
A:
- "Hello, I’m one of the doctors in A&E. Could I confirm your full name and date of birth? Thank you. I understand you’ve been having abdominal discomfort – could you tell me more about that?"
- Keywords: Introduction, confirm identity, open-ended question.
Term
2. PRESENTING COMPLAINT (SOCRATES)
Q: What SOCRATES questions would you ask about abdominal pain?
Definition
A:
- Site: "Where exactly is the pain?"
- Onset: "When did it start?" (e.g., today)
- Character: "How would you describe it?" (cramping?)

- Time: "Has the pain changed?"
- Exacerbating/Relieving: "Does anything worsen/relieve it?"
- Severity: "On a scale of 1–10?"
- Keywords: SOCRATES, cramping, radiation, severity scale.
Term
4. RISK FACTORS
Q: What obstruction-specific risk factors would you ask about?


---
Definition
A:
- "Any prior abdominal surgery?" (→ adhesions)
- "History of bowel cancer, polyps, or chronic constipation?"
- "Taking opioids, anticholinergics, antidepressants?"
- Keywords: Prior surgery (commonest cause), opioids, cancer.
Term
5. PMAFTOSA HISTORY Q: Outline the PMAFTOSA framework.
Definition
A: - Past Medical: Bowel disease, cancer, surgery. - Medications: Laxatives, opioids, antibiotics. - Allergies: Especially to analgesics/antibiotics. - Family: Colon cancer, IBD. - Travel: Infectious risks. - Occupation/Social: Smoking, alcohol, diet. - Alcohol/Opioids: "Any regular use?" (chronic constipation). - Keywords: PMAFTOSA, opioids, alcohol, family history. ---
Term
7. EFFECT ON LIFE
Q: How does obstruction impact daily life?
Definition
A:
- "Has this affected your appetite, sleep, or routine?"
- Expected: Unable to eat, bloating, fatigue.
- Keywords: Appetite loss, bloating, fatigue.

---
Term
8. EXAMINATION (SCENARIO-SPECIFIC)
Q (All Scenarios): How would you introduce the abdominal exam?
Definition
A: "I’d like to examine your abdomen now – this involves looking and gently pressing. Is that okay?"
Term
Scenario 1 & 2 (Mannequin):
Q: What are key findings?
Definition
A:
- Inspection: Distension, scars, visible peristalsis.
- Palpation: Discomfort on light/deep palpation.
- Auscultation: Increased bowel sounds (examiner states this).
- Skip percussion (due to pain).
Term
Scenario 3 (Real Patient):
Q: How does the exam differ?
Definition
A:
- Caution: "This might cause discomfort – tell me if it hurts."
- Auscultation: Silent abdomen (examiner states this → red flag).
- Lactate check: Request in blood tests (indicates ischemia).
- Keywords: Distension, increased sounds (Sc1/2), silent abdomen (Sc3), lactate.

---
Term
9. PROVISIONAL DIAGNOSIS & EXPLANATION
Q: How would you explain suspected bowel obstruction?
Definition
A:
- "I’m concerned about a bowel obstruction – a blockage preventing stool/gas from passing."
- "Causes include scar tissue, a twist, or growth. We’ll do urgent tests to confirm and treat it."
- Keywords: Blockage, scar tissue, urgent tests.

---
Term
10. MANAGEMENT PLAN
A. Immediate Stabilisation (All Scenarios):
Q: What are the ABC steps?


B. Investigations:
Q: What tests would you order?
A:
- Bloods: FBC, U&Es, CRP, LFTs, Group & Save, lactate (Sc3) .
- Sc1: Abdominal X-ray (dilated loops) → CT abdomen/pelvis (gold standard).
- Sc2/3: No imaging during exam.
- Keywords: X-ray (Sc1), CT (Sc1), lactate (Sc3).

C. Escalation:
Q: What urgent steps follow?
A:
- Refer to surgeons immediately (all scenarios).
- Sc3: Highlight "silent abdomen + high lactate = possible ischemia" (surgical emergency).

D. Monitoring:
Q: What ongoing care is needed?
A:
- Regular obs, fluid balance, urine output.
- Continue pain/nausea control.
- Keywords: Surgical referral, obs monitoring.

---

11. SAFETY NETTING & FOLLOW-UP
Q: What advice would you give?
A:
- "We’ll monitor you closely. If pain/vomiting worsens, or you feel dizzy/feverish, alert us immediately."
- "Surgeons will decide if surgery is needed."
- Keywords: Worsening pain, fever, dizziness, urgent review.

SCENARIO QUICK REFERENCE
| Feature | Scenario 1 | Scenario 2 | Scenario 3 |
|----------------------|----------------------|----------------------|------------------------------|
| Patient | 50M, no stool ×4d | Female, no stool ×2d | Real patient, ruptured appy |
| Gas | None ×2d | None ×1d | Advanced symptoms |
| Bowel Sounds | Increased | Increased | Silent (ischemia risk) |
| Imaging | X-ray → CT | None | None |
| Key Action | NG tube, surgical ref| Same as Sc1 | Check lactate |

Key Mnemonics:
- SOCRATES: Pain assessment framework.
- PMAFTOSA: Comprehensive history.
- NG Tube: Essential for decompression.
- Silent Abdomen + Lactate = Ischemia (Sc3).
