Title at top in bold dark green: "OP POISONING: DIAGNOSIS" Section 1 - CLINICAL DIAGNOSIS (yellow background box): "Diagnosis is CLINICAL - Do NOT wait for labs" Key triad: Miosis + Bradycardia + Excessive secretions Garlic/hydrocarbon odor History of pesticide/nerve agent exposure Response to atropine (diagnostic AND therapeutic) Section 2 - SEVERITY GRADING table with 3 rows: MILD: Miosis, salivation, lacrimation, diaphoresis, nausea - RBC AChE: 20-50% of normal MODERATE: Above + bronchospasm, vomiting, muscle weakness, bradycardia - RBC AChE: 10-20% of normal SEVERE: Above + seizures, coma, apnea, respiratory failure, paralysis - RBC AChE: <10% of normal Section 3 - LAB TESTS box: Plasma Butyrylcholinesterase (first to fall, quicker): decreased >50% = significant RBC Acetylcholinesterase (more accurate, gold standard): reduced to <10-20% in moderate/severe Note: Labs confirm but should NOT delay treatment Section 4 - DIFFERENTIAL DIAGNOSIS box: Carbamate poisoning | Nerve agent exposure | Myasthenia gravis | Botulism | Bradycardia from other causes Bottom red alert: "Miosis + Bradycardia + Bronchorrhea + Garlic odor = OP poisoning until proven otherwise" White background, organized boxes with color coded sections, large readable medical flashcard style.

Medical clinical flowchart flashcard for Organophosphate (OP) Poisoning Management. Title at top in bold white on dark red background: "OP POISONING: MANAGEMENT FLOWCHART" Show a clear top-to-bottom flowchart with decision boxes: [START] Patient with suspected OP poisoning ↓ [STEP 1 - RED BOX] DECONTAMINATION Remove clothing, wash skin with soap/water, eye irrigation Staff use PPE (gloves, gown, mask) ↓ [STEP 2 - ORANGE BOX] ABC STABILIZATION Airway - suction secretions, O2 Breathing - ventilatory support if needed Circulation - IV access, cardiac monitor Note: Prefer ROCURONIUM (1mg/kg) over succinylcholine for RSI (succinylcholine prolonged effect in OP) ↓ [STEP 3 - BLUE BOX] ANTIDOTE 1: ATROPINE (FIRST LINE) Adults: 1-3 mg IV (children: 0.05 mg/kg) Double dose every 5 minutes until: ENDPOINT = Dry secretions + Normal RR + Ease of breathing Then: maintenance infusion = 10-20% of total loading dose per hour NOT endpoint: heart rate or pupil size Tachycardia/mydriasis = acceptable, do not stop ↓ [STEP 4 - GREEN BOX] ANTIDOTE 2: PRALIDOXIME (2-PAM) - OXIME Adults: 1-2g IV over 30 min (children: 25-50 mg/kg) Must give BEFORE AGING occurs Repeat based on response Mechanism: regenerates AChE from OP-AChE complex ↓ [STEP 5 - PURPLE BOX] SEIZURES Benzodiazepines (diazepam/lorazepam) - FIRST LINE NO role for phenytoin ↓ [STEP 6 - GRAY BOX] DECONTAMINATION GI Activated charcoal if ingestion within 1 hour + patient not obtunded NO enhanced elimination (no role for hemodialysis) ↓ [BOTTOM BOX] DISPOSITION Symptomatic → ICU admission Asymptomatic + normal/minimal cholinesterase drop → observe 6 hours, discharge with follow-up Watch for: Intermediate Syndrome (24-96hrs), Delayed Neuropathy (7-21 days) Clean white background, colored boxes, arrows between steps, medical textbook quality.
