Here's your aesthetic revision note page for Acute Pancreatitis! 🎉
Here's a quick rundown of everything packed into the notes:
Definition - Acute inflammatory condition with enzymatic autodigestion, ranging mild to life-threatening.
Etiology - "GET SMASHED" mnemonic:
- Gallstones (#1, 40-70%) | Ethanol (#2, 25-35%) | Trauma | Steroids | Mumps/Metabolic | Autoimmune | Scorpion sting | Hypertriglyceridemia/Hypercalcemia | ERCP | Drugs
Pathogenesis flow: Trigger → Blocked duct → Premature trypsinogen activation → Autodigestion → SIRS → Mild OR Necrotizing
Classic signs: Grey Turner (flank bruising) + Cullen (periumbilical bruising) = hemorrhagic pancreatitis
Investigations: Lipase >3x ULN (more specific than amylase) | CECT abdomen is gold standard (best at 72h)
Severity: Revised Atlanta Classification | Ranson's Criteria (≥3 = severe)
Management: IV fluids (LR preferred) → Pain control → Early enteral nutrition → ERCP if cholangitis → Cholecystectomy before discharge
Memory trick: GET SMASHED = all causes. One-liner: "Premature enzyme activation → autodigestion → inflammation → SIRS"

| Thrombin (coagulopathy) | 1% |
Drug Ladder - Doses & Contraindications
| Drug | Dose | Contraindications |
|---|---|---|
| Oxytocin (1st line) | 10 IU IM/slow IV; 40 IU in 500 mL infusion | Rapid IV → hypotension |
| Ergometrine | 500 mcg IM or 250 mcg IV slowly | Hypertension, pre-eclampsia, cardiac disease |
| Syntometrine | 1 mL IM | Hypertension, cardiac disease |
| Carboprost (PGF2α) | 250 mcg IM q15 min, max 8 doses (2 mg) | ASTHMA (absolute CI), hepatic/renal disease |
| Misoprostol (PGE1) | 800-1000 mcg PR or 600-800 mcg SL | Cardiovascular disease (caution) |
| Tranexamic Acid | 1g IV over 10 min; repeat after 30 min if needed (within 3 hrs) | Thromboembolism risk (caution) |
Classic Exam MCQ Contraindications
- Ergometrine ❌ = Hypertension / Pre-eclampsia
- Carboprost ❌ = Asthma (absolute contraindication)
- Tranexamic acid - give within 3 hours (WOMAN trial evidence)
Surgical Ladder (when drugs fail)
Uterine massage → Balloon tamponade → B-Lynch suture → Uterine artery ligation → Internal iliac ligation → Hysterectomy (last resort)
Memory trick: "Tone Trauma Tissue Thrombin" | Drug order: Oxytocin → Ergometrine → Carboprost → Misoprostol → Surgery

Here's your Eclampsia Management revision page! ⚡
Here's the full high-yield text breakdown:
Eclampsia - Complete Management Summary
Definition: New-onset grand mal seizures in a woman with pre-eclampsia (no other neurological cause). Can occur antepartum (38%), intrapartum (18%), or postpartum (44% - most common!).
Immediate Steps (ABC + obstetric)
- Left lateral position (aortocaval decompression)
- O2 via face mask + protect airway
- 2× large-bore IV + bloods (FBC, U&E, LFTs, coag, crossmatch)
- Foley catheter - strict hourly urine output (target >25-30 mL/hr)
- Continuous CTG monitoring
- MgSO4 → seizure control
- Antihypertensives → if BP ≥160/110
- Deliver after stabilization
MgSO4 - Drug of Choice
| Protocol | Loading Dose | Maintenance |
|---|---|---|
| IV | 4–6 g in 100 mL NS over 15–20 min | 1–2 g/hr for 24 hrs after last seizure/delivery |
| IM (no IV access) | 10 g IM (5 g each buttock) | 5 g IM every 4 hrs |
| Recurrent seizure | Extra 2 g IV bolus | Increase infusion rate |
Therapeutic level: 4–8 mEq/L
MgSO4 Toxicity - "R-R-C" Mnemonic
| Mg Level | Effect |
|---|---|
| 5–10 mEq/L | Loss of patellar reflexes (FIRST sign!) |
| 10–13 mEq/L | Respiratory depression |
| >15 mEq/L | Cardiac arrest |
Check TRIAD before each dose:
- ✅ Patellar reflex present
- ✅ RR >12/min
- ✅ Urine output >25 mL/hr
ANTIDOTE = Calcium Gluconate 1 g IV over 10 min (keep at bedside always!)
CI to MgSO4: Myasthenia gravis | Severe renal failure | Heart block
Antihypertensives (target BP <160/110)
| Drug | Dose | Contraindication |
|---|---|---|
| Labetalol (1st line) | 20 mg IV → repeat 40–80 mg q10 min; max 300 mg | Asthma, heart block, bradycardia |
| Hydralazine | 5–10 mg IV q20 min; max 30 mg | Lupus, aortic dissection |
| Nifedipine (oral) | 10–20 mg oral; repeat in 30 min | Caution with MgSO4 (additive hypotension) |
| Nicardipine | 5–15 mg/hr IV infusion | - |
Absolute CI in pregnancy: ACE inhibitors, ARBs, direct renin inhibitors
Key Exam MCQs
- MgSO4 = 1st line (NOT phenytoin, NOT diazepam as primary)
- Patellar reflex = first thing to disappear in toxicity
- Calcium gluconate = antidote
- Labetalol CI = Asthma
- Delivery = only definitive treatment; continue MgSO4 for 24 hrs postpartum
Memory trick: MgSO4 toxicity sequence: Reflexes → Respiration → Cardiac (R-R-C)
One-liner: "Eclampsia = seize the moment to give MgSO4, lower BP, then deliver!"
1p0ml NS or 13 ml NS for 4g Mgso4
Great practical question! Let me work through the exact calculation.
MgSO4 comes in a 50% solution = 500 mg/mL (i.e., 0.5 g/mL)
So for a 4 g loading dose:
4 g ÷ 0.5 g/mL = 8 mL of 50% MgSO4
How much diluent (NS)?
The standard practice across guidelines (WHO, RCOG, ACOG) is to dilute 4 g MgSO4 into 100 mL NS, giving a final volume of ~108 mL, infused over 15–20 minutes.
- 100 mL NS is correct for IV administration
- Neither "10 mL NS" nor "13 mL NS" is a standard dilution for the loading dose
Where does the confusion come from?
Some units use a more concentrated preparation for space/resource-limited settings:
| Preparation | MgSO4 vol | Diluent | Total vol | Infuse over |
|---|---|---|---|---|
| Standard (WHO/RCOG) | 8 mL (50%) | 92 mL NS → total 100 mL | 100 mL | 15–20 min |
| Concentrated (some protocols) | 8 mL (50%) | 12 mL NS → total 20 mL | 20 mL | 10–15 min slow push |
| Pritchard IM protocol | 10 g IM (5 g each buttock) | No diluent | — | — |
So "13 mL NS" does not correspond to any standard guideline. The closest would be 12 mL NS to make a 20 mL total concentrated bolus.
Bottom line
| Question | Answer |
|---|---|
| Volume of 50% MgSO4 for 4 g | 8 mL |
| Standard diluent | 92 mL NS (total 100 mL) |
| "10 mL NS" correct? | ❌ No standard protocol |
| "13 mL NS" correct? | ❌ No standard protocol |
| Correct standard dilution | 8 mL MgSO4 + 92 mL NS = 100 mL total |
If your unit uses a specific local protocol with a different concentration, always follow that protocol - but 100 mL NS is the internationally recommended standard for a 4 g IV loading dose.
