I now have enough library context combined with my comprehensive clinical knowledge to give you a thorough answer. Here is a complete management guide with doses for all six conditions:
Management Guide with Doses
1. Acute Myocardial Infarction (AMI)
STEMI Management (time-sensitive - "Door-to-balloon < 90 min")
Immediate (first 10 min) - MONA + Antiplatelet:
| Drug | Dose | Route | Notes |
|---|---|---|---|
| Aspirin | 300 mg loading, then 75-100 mg/day | PO | Chew immediately |
| Clopidogrel | 600 mg loading, then 75 mg/day | PO | Or Ticagrelor |
| Ticagrelor | 180 mg loading, then 90 mg BD | PO | Preferred over clopidogrel |
| Prasugrel | 60 mg loading, then 10 mg/day | PO | If PCI planned (not if age >75 or prior stroke) |
| Morphine | 2-4 mg IV, repeat q5-15 min PRN | IV | For chest pain (use cautiously) |
| Oxygen | 2-4 L/min via nasal cannula | Inhalation | Only if SpO2 <90% |
| Nitrates | GTN 0.4 mg sublingual q5 min x3, then IV infusion 10-200 mcg/min | SL / IV | Avoid if hypotension, RV infarct, or PDE5i use |
Anticoagulation (choose one):
| Drug | Dose | Notes |
|---|---|---|
| Heparin (UFH) | 60 U/kg IV bolus (max 4000 U), then 12 U/kg/hr (max 1000 U/hr) | Adjust to aPTT 50-70 sec |
| Enoxaparin (LMWH) | 1 mg/kg SC BD (or 0.75 mg/kg if age >75) | Dose reduce if CrCl <30 |
| Fondaparinux | 2.5 mg SC daily | Not for primary PCI |
| Bivalirudin | 0.75 mg/kg IV bolus, then 1.75 mg/kg/hr | For PCI |
Beta-Blockers (within 24h if hemodynamically stable):
| Drug | Dose |
|---|---|
| Metoprolol | 25-50 mg PO BD (start low), or 5 mg IV q5 min x3 doses |
| Carvedilol | 3.125-25 mg PO BD |
| Atenolol | 50-100 mg PO daily |
ACE Inhibitors/ARBs (within 24h, especially if EF <40%):
| Drug | Dose |
|---|---|
| Ramipril | 2.5 mg PO BD, titrate to 5 mg BD |
| Lisinopril | 5 mg PO daily, titrate to 10-20 mg/day |
| Enalapril | 2.5 mg BD, titrate to 10 mg BD |
| Valsartan (if ACEi intolerant) | 40 mg BD, titrate to 160 mg BD |
Statins (high-intensity, start immediately):
| Drug | Dose |
|---|---|
| Atorvastatin | 80 mg PO at night |
| Rosuvastatin | 20-40 mg PO at night |
Reperfusion:
- Primary PCI: preferred if available within 120 min
- Thrombolysis (if PCI not available within 120 min):
- Streptokinase: 1.5 million U IV over 60 min
- Alteplase (tPA): 15 mg IV bolus, then 0.75 mg/kg over 30 min (max 50 mg), then 0.5 mg/kg over 60 min (max 35 mg)
- Tenecteplase (TNK-tPA): weight-based single IV bolus (30-50 mg)
2. Organophosphate (OP) Poisoning
OP compounds inhibit acetylcholinesterase, causing accumulation of ACh - producing SLUDGE/DUMBELS (Salivation, Lacrimation, Urination, Defecation, GI cramps, Emesis + Bradycardia, Bronchospasm, Miosis).
Management Steps:
A. Decontamination:
- Remove clothing, wash skin with soap and water
- Activated charcoal 1 g/kg PO if ingested and airway protected (within 1 hour)
B. Specific Antidotes:
| Drug | Dose | Route | Notes |
|---|---|---|---|
| Atropine | 2-4 mg IV bolus, then DOUBLE every 5-10 min until secretions dry ("atropinized") | IV | Titrate to drying of secretions (NOT heart rate). May need hundreds of mg in severe cases |
| Pralidoxime (2-PAM) | 1-2 g IV over 15-30 min, then 200-400 mg/hr infusion | IV | Give within 24-48h (before "aging"); continue for 24-48h after atropine stopped |
| Diazepam | 5-10 mg IV, repeat as needed | IV | For seizures/prevent organophosphate-induced seizures |
C. Supportive:
- Secure airway early (beware of succinylcholine - AVOID, use rocuronium instead)
- Mechanical ventilation if respiratory failure
- Fluid resuscitation
- ECG monitoring (QTc prolongation)
3. Morphine (Opioid) Poisoning
Classic Triad: Miosis, Respiratory depression, Reduced consciousness (coma)
Management:
A. Immediate:
- Airway, Breathing, Circulation
- Do NOT induce vomiting
- Activate charcoal only if recent ingestion and airway protected
B. Specific Antidote - Naloxone:
| Indication | Dose | Route | Notes |
|---|---|---|---|
| Respiratory depression (adult) | 0.4-2 mg IV/IM/SC | IV preferred | Repeat every 2-3 min if no response |
| Severe coma/arrest | Up to 10 mg total | IV | If no response after 10 mg, question opioid diagnosis |
| Infusion (for long-acting opioids) | 2/3 of reversal dose per hour | IV infusion | Run as continuous infusion |
| Intranasal (if no IV access) | 4 mg per nostril | Intranasal | Narcan nasal spray |
| Paediatric dose | 0.01 mg/kg IV | IV | Then 0.1 mg/kg if no response |
Key: Naloxone half-life (60-90 min) is shorter than most opioids - patient may re-narcotize. Monitor for 4-6 hours minimum. Observe 12-24h for long-acting opioids (e.g., methadone, modified-release morphine).
C. Supportive:
- Mechanical ventilation if respiratory failure
- Treat pulmonary edema (can occur with opioid overdose)
- Correct hypoglycemia
4. Paraquat Poisoning
Paraquat is an extremely toxic herbicide. It causes oxidative stress and multi-organ failure (primarily lungs - progressive fibrosis, kidney, liver).
Prognosis is poor. No universally approved antidote. Survival depends on dose ingested.
Management:
| Step | Intervention | Dose/Details |
|---|---|---|
| Decontamination | Fuller's earth or activated charcoal (do NOT delay) | Fuller's earth: 500 mL of 15% solution PO, OR activated charcoal 1 g/kg |
| GI decontamination | Cathartics + gastric lavage (within 1h) | Magnesium sulfate 15 g or mannitol 200 mL 20% as cathartic |
| Antioxidants | Vitamin C (ascorbic acid) | 2 g IV every 4-6 hours |
| Vitamin E (tocopherol) | 400 IU PO daily | |
| N-acetylcysteine (NAC) | 150 mg/kg IV over 60 min, then 50 mg/kg over 4h, then 100 mg/kg over 16h | |
| Immunosuppression | Pulse methylprednisolone + cyclophosphamide | Methylprednisolone 1 g/day IV x3 days; Cyclophosphamide 5 mg/kg/day x14 days |
| Oxygen | AVOID supplemental O2 unless SpO2 <70% | Hyperoxia accelerates paraquat toxicity via free radical generation |
| Hemoperfusion | Activated charcoal hemoperfusion within 4h | Best within 4 hours of ingestion |
| Supportive | Renal replacement therapy if AKI; IV fluids | Avoid aggressive fluid |
CRITICAL: Oxygen is contraindicated unless SpO2 <70% - it worsens paraquat lung injury.
5. Dyslipidemia (General) & Hypertriglyceridemia
Dyslipidemia - Drug Therapy:
High-Intensity Statins (LDL lowering - first-line):
| Drug | Dose | LDL Reduction |
|---|---|---|
| Atorvastatin | 40-80 mg PO at night | ~50% |
| Rosuvastatin | 20-40 mg PO at night | ~50-55% |
Moderate-Intensity Statins:
| Drug | Dose | LDL Reduction |
|---|---|---|
| Atorvastatin | 10-20 mg/day | ~30-40% |
| Simvastatin | 20-40 mg/day | ~30-40% |
| Pravastatin | 40-80 mg/day | ~30-40% |
Add-on therapy (if statin insufficient):
| Drug | Dose | Indication |
|---|---|---|
| Ezetimibe | 10 mg PO daily | LDL reduction (+18-20%) |
| Evolocumab (PCSK9i) | 140 mg SC q2 weeks or 420 mg SC monthly | High-risk, LDL still elevated |
| Alirocumab (PCSK9i) | 75-150 mg SC q2 weeks | High-risk, LDL still elevated |
| Fenofibrate | 145-200 mg PO daily | High TG, low HDL |
| Omega-3 (icosapent ethyl) | 4 g/day PO in divided doses | High TG + residual CV risk |
| Niacin | 1-3 g/day (extended release) | Rarely used now (TG + HDL) |
| Bile acid sequestrants (cholestyramine) | 4-16 g/day | LDL only, not TG |
Hypertriglyceridemia Specifically:
| TG Level | Category | Management |
|---|---|---|
| 150-199 mg/dL | Borderline high | Lifestyle modification |
| 200-499 mg/dL | High | Lifestyle + consider fibrate/omega-3 |
| 500-999 mg/dL | Very high | Drug therapy (fibrate or omega-3) - pancreatitis risk |
| ≥1000 mg/dL | Severely high | Urgent treatment - high pancreatitis risk; consider hospitalization |
Drug Therapy for Hypertriglyceridemia:
| Drug | Dose | Mechanism |
|---|---|---|
| Fenofibrate | 145-200 mg/day PO (micronized) | PPAR-alpha agonist - reduces TG 30-50% |
| Gemfibrozil | 600 mg PO BD (30 min before meals) | Fibrate - reduces TG; caution with statins (myopathy) |
| Omega-3 fatty acids (Icosapent ethyl) | 4 g/day PO in 2 divided doses | Reduces TG 20-30%; CV benefit in REDUCE-IT trial |
| Omega-3 carboxylic acids | 4 g/day PO | Reduces TG |
| Niacin | 1-3 g/day (extended release) | Reduces TG 20-35% |
Lifestyle: Weight loss, low-fat diet, reduce refined carbs/alcohol, treat secondary causes (DM, hypothyroidism).
