IM22.1-13 | Poisoning — Assignment

CLINICAL SCENARIO

This assignment asks you to prepare a structured clinical case report for one of three assigned poisoning scenarios (your faculty will allocate your case). The three scenarios are: (A) a 28-year-old farmer with severe organophosphate poisoning requiring atropine titration and pralidoxime; (B) a 40-year-old man with aluminium phosphide (Celphos) poisoning with cardiovascular collapse — no antidote available; (C) a 23-year-old who ingested 15 g of paracetamol in a deliberate self-harm episode. For your assigned case, you will analyse the toxidrome, construct the management plan with exact antidote dosing or justify the absence of an antidote, address decontamination decisions, complete the medico-legal documentation obligations, and write a family counselling script or psychiatric referral note. This task integrates clinical pharmacology, emergency management, and medical communication in a single structured exercise.

Instructions

Write a structured case report in the six sections below for your allocated poisoning scenario. Use precise clinical language — name drugs with doses, name receptors and enzymes, name the clinical endpoints for titration. Do not write in generic terms. For the medico-legal section, apply the Indian legal framework (MLC under BNSS 2023 / IPC framework). For the counselling section, write as though speaking to the actual family — not as an academic exercise. Do not copy SDL text verbatim. Word limit: 1,100–1,500 words.

Length: 1,100–1,500 words across all sections

What to Submit

Section 1: Clinical Assessment and Toxidrome Identification

Guidance: Identify the toxidrome present in your assigned case. Name the class of toxin, the specific molecular target (receptor or enzyme), and the pathophysiological cascade linking the toxin's mechanism to each major clinical feature observed. Use SLUDGE/DUMBELS terminology for cholinergic features where applicable. Approximately 200 words.

Section 2: Antidote and Resuscitation Management Plan

Guidance: State the specific antidote for your assigned case (or confirm that no antidote exists). For antidote-available cases: state the drug, initial dose, route, titration principle, and the exact clinical endpoint for titration (e.g., for OP poisoning — dry secretions, not tachycardia or pupil size). For phosphide poisoning: describe the complete supportive care framework. Include any contraindicated interventions and explain why they are contraindicated. Approximately 300 words.

Section 3: Decontamination Decision and Activated Charcoal Limits

Guidance: For your assigned case, determine whether activated charcoal is appropriate, contraindicated, or of limited utility. State the general time window for activated charcoal efficacy. Explain the specific contraindications relevant to your case (e.g., reduced GCS risk of aspiration, corrosive exposure, phosphine gas toxicity risk). Describe any surface decontamination steps required (contaminated clothing, skin wash). Approximately 150 words.

Section 4: Medico-Legal Documentation

Guidance: Your assigned case is a medico-legal case (MLC). (a) List the mandatory components of the medico-legal report (MLR) for this case. (b) State under which specific circumstances police notification is obligatory in India. (c) Explicitly state what the physician must NOT include in the MLR regarding the question of suicidal or homicidal intent — and who makes that determination. Approximately 200 words.

Section 5: Family Counselling Script or Psychiatric Referral Note

Guidance: For Case A or B (OP or AlP): Write a 150-200 word counselling script for the immediate family, covering: (a) what the poison is and what it is doing; (b) what treatments are being given; (c) the prognosis stated honestly, without minimising the seriousness; (d) an invitation for questions. For Case C (paracetamol/DSH): Write a psychiatric referral note covering: the reason for referral, the clinical context, the specific risk assessment question you are asking psychiatry to answer, and any safety precautions currently in place. Approximately 200 words.

Section 6: Reflective Note on Limits of Medicine

Guidance: Reflect briefly on the distinction between poisonings where medicine has a specific pharmacological solution (antidote) and those where we can only support organs while the toxin runs its course. How does this distinction inform how you communicate with families, and what does it mean to practise honestly within these limits? Approximately 150 words.

Grading Rubric — Acute Poisoning Case Report Rubric

Criterion	Points	Full-marks descriptor
Clinical Assessment and Toxidrome Identification (Section 1): Accurately identifies the toxidrome from the clinical scenario; names the class of toxin and explains the pathophysiological mechanism linking toxin to clinical features.	20 pts	Toxidrome correctly identified with full pathophysiological explanation; mechanism linked to receptor/enzyme target; all cardinal clinical features accounted for.
Antidote and Resuscitation Management Plan (Section 2): Correctly states antidote (or confirms no antidote), dosing principle, titration endpoint, and supportive care sequence for the assigned case; all antidote-toxin pairings are exact.	25 pts	All antidote-toxin pairings exact; titration endpoint stated precisely (e.g., dry secretions for OP); supportive care sequence logical and complete; contraindicated interventions correctly excluded.
Decontamination Decision and Activated Charcoal Limits (Section 3): Correctly decides whether activated charcoal and decontamination are applicable; states the time window, contraindications, and specific exceptions relevant to the case.	15 pts	Decontamination decision correct with clear justification; activated charcoal contraindications (reduced GCS, corrosive, phosphide) explicitly stated; time window addressed.
Medico-Legal Documentation (Section 4): Correctly identifies the case as an MLC; outlines the MLR content accurately; states the police notification trigger; does NOT conclude on suicidal or homicidal intent.	20 pts	MLC status correctly affirmed; MLR components fully enumerated; correct police notification criteria stated; explicit statement that intent classification is for the magistrate, not the physician.
Family Counselling and Psychiatric Referral (Section 5): Demonstrates communication skills for counselling a family facing a grave prognosis (AlP) or initiating psychiatric referral after deliberate self-harm.	15 pts	Counselling script is honest, empathic, and specific; prognosis stated clearly without false reassurance; limitations of medicine acknowledged; psychiatric referral indications precise with correct framing (not punitive).
Reflection on Limitations of Medicine (Section 6): Reflects specifically on the distinction between poisonings with antidotes and those with supportive care only; demonstrates ethical clarity about honest prognosis disclosure.	5 pts	Reflection is specific, honest, and demonstrates ethical maturity; clearly distinguishes antidote-available from supportive-only poisonings; reflects on the duty to disclose prognosis honestly.

PEER REVIEW

Review your peer's case report using the rubric provided. For each section, assign a score and write one specific comment. Check the following: (1) Is the atropine titration endpoint precisely stated as dry secretions (not tachycardia)? (2) Does the AlP management correctly state no antidote and no activated charcoal? (3) Is the MLR section explicit that the physician must NOT opine on suicidal/homicidal intent? (4) Is the family counselling script honest about prognosis — does it avoid false reassurance? Complete your review within 72 hours of receiving the assignment.
