I have everything I need. Here is the full case analysis and IV treatment protocol for Muffin:
🐾 Muffin - Case Summary & IV Treatment Protocol
Species: Dog | Age: 5 Years | Sex: Male
Date: 11/08/2026 | Ref. by: Dr. Aradhana
Diagnosis: Ehrlichia canis positive + Lethargy/Dullness + Ascites
Biochemistry Interpretation
| Parameter | Result | Status | Clinical Significance |
|---|---|---|---|
| Serum Albumin | 2.1 g/dL | LOW | Hypoalbuminemia - key cause of ascites |
| Total Protein | 6.3 g/dL | Normal | - |
| SGOT (AST) | 216 IU/L | HIGH | Severe hepatocellular damage |
| SGPT (ALT) | 401 IU/L | HIGH | Severe hepatocellular damage |
| GGT | 20 U/L | HIGH | Biliary/hepatic involvement |
| ALP | >1183 IU/L | VERY HIGH | Marked hepatic/biliary disease |
| Total Bilirubin | 7.90 mg/dL | HIGH | Hepatic jaundice / icterus |
| Uric Acid | 2.6 mg/dL | LOW | - |
| Calcium | 9.0 mg/dL | LOW | Mild hypocalcemia |
| Sodium | 139 mmol/L | LOW | Mild hyponatremia |
| Chloride | 97 mmol/L | LOW | Hypochloremia |
| BUN & Creatinine | Normal | Normal | Renal function preserved |
Key Pathophysiology:
- Severe hepatopathy (massively elevated liver enzymes + hyperbilirubinemia) from E. canis - this organism infects monocytes and causes widespread organ inflammation including the liver
- Hypoalbuminemia (2.1 g/dL) is the primary driver of ascites - low oncotic pressure leads to fluid accumulation
- Electrolyte imbalances (hyponatremia, hypochloremia) likely from fluid shifts and poor hepatic function
IV Treatment Protocol (Hospital Management)
1. Anti-Rickettsial Therapy (PRIMARY - START IMMEDIATELY)
Doxycycline IV
- Dose: 5 mg/kg IV every 12 hours (or 10 mg/kg IV every 24 hours)
- Route: IV infusion diluted in 0.9% NaCl or 5% dextrose, given slowly over 1-2 hours
- Duration: 28 days total (switch to oral doxycycline as soon as patient tolerates food)
- Note: IV doxycycline must be administered slowly - rapid infusion causes vascular irritation and collapse
If doxycycline IV is not available: Minocycline 5-10 mg/kg IV/PO every 12 hours is acceptable.
Fever should resolve within 24-48 hours of starting treatment. Clinical improvement is typically rapid in the first 72 hours.
2. Fluid & Electrolyte Support
IV Fluid Therapy:
- Start with Ringer's Lactate (RL) or 0.9% NaCl at maintenance rate: ~50-60 mL/kg/day
- Caution: Do not over-hydrate - this patient has hypoalbuminemia and ascites; excess IV fluids will worsen third-spacing
- Correct hyponatremia and hypochloremia gradually with balanced crystalloids
- Monitor urine output closely
Potassium supplementation: Potassium is currently normal (4.3 mmol/L) but monitor daily as hypokalemia can develop with fluid diuresis.
3. Albumin / Oncotic Support (for Ascites)
The ascites is primarily from hypoalbuminemia (2.1 g/dL - below 2.0 is critical threshold for ascites development).
Options:
- Fresh Frozen Plasma (FFP): 10-20 mL/kg IV slowly over 4-6 hours - provides albumin + clotting factors (important given hepatic dysfunction)
- Human Serum Albumin (25% solution): 0.5-1.5 g/kg IV as a constant rate infusion if available - more concentrated oncotic support (use with caution - anaphylaxis risk in dogs)
- Furosemide: 1-2 mg/kg IV BID cautiously to help mobilize ascitic fluid - only after albumin is improved, otherwise worsens hypoalbuminemia further
4. Hepatoprotective Support (Critical given Massive Liver Damage)
| Drug | Dose | Route | Frequency |
|---|---|---|---|
| SAMe (S-adenosylmethionine) | 20 mg/kg | PO (empty stomach) | Once daily |
| Silymarin (Milk Thistle) | 50-70 mg/kg | PO | Once daily |
| Ursodeoxycholic acid (Ursodiol) | 10-15 mg/kg | PO | Once daily |
| Vitamin E | 10 IU/kg | PO | Once daily |
| N-Acetylcysteine (NAC) | 70 mg/kg IV loading, then 35 mg/kg | IV (slow) | Every 6 hours for 24-48 hrs |
ALP >1183 and ALT 401 indicate serious hepatic compromise - hepatoprotectants are non-negotiable in this case.
5. Anti-Nausea / GI Protection
| Drug | Dose | Route | Frequency |
|---|---|---|---|
| Maropitant (Cerenia) | 1 mg/kg | SC / IV slow | Once daily |
| Omeprazole | 1 mg/kg | IV / PO | Once daily |
| Metronidazole | 10-15 mg/kg | IV slow | BID (also has anti-inflammatory hepatic effect) |
6. Appetite & Nutritional Support
- Muffin is lethargic/dull - assisted feeding or nutritional support may be needed
- If not eating voluntarily: consider syringe feeding or nasogastric (NG) tube with high-quality hepatic support diet
- Hepatic diet (low copper, high antioxidants, moderate high-quality protein) - e.g., Royal Canin Hepatic or Hill's l/d
- Avoid high-copper foods
- Small, frequent meals
7. Monitoring Parameters (Daily)
| Parameter | Frequency | Target |
|---|---|---|
| Temperature, Pulse, Respiration | Every 6-8 hours | Temp normalize in 24-48 hrs |
| Abdominal girth / ascites | Daily | Gradual reduction |
| ALT, AST, ALP, Bilirubin | Every 3-5 days | Downtrend expected |
| Albumin | Every 3-5 days | Target >2.5 g/dL |
| Electrolytes (Na, K, Cl) | Daily | Normalize |
| PCV/Total Solids | Daily | Monitor for anemia |
| Platelet count | Daily | E. canis causes thrombocytopenia |
| Urine output | Daily | >1 mL/kg/hr |
8. Tick Control (Prevent Re-infection)
- Apply Fipronil (Frontline) or Amitraz collar immediately
- Treat environment for ticks
- Consider Fluralaner (Bravecto) or Afoxolaner (NexGard) for ongoing prevention
Prognosis
Muffin is in the acute/subacute phase of E. canis infection with secondary severe hepatopathy. The prognosis is guarded to fair if:
- Doxycycline is started immediately
- Hepatic support is aggressive
- Albumin is raised above 2.0 g/dL to reduce ascites
Dogs in the acute phase who receive prompt doxycycline treatment typically show rapid clinical improvement within 48-72 hours. Liver enzyme elevation can persist for 4-8 weeks even after the infection clears.
Follow-up: PCR test for E. canis 2 weeks after completing the 28-day doxycycline course to confirm clearance.

🐾 MUFFIN - CBC Analysis & Updated Treatment Protocol
Collected: 12/08/2026 | Lab: PathVets C R Park | Ref by: Dr. Ankit Verma
CBC Interpretation
| Parameter | Result | Range | Status | Significance |
|---|---|---|---|---|
| Hemoglobin | 11.7 g/dL | 12-18 | LOW | Mild anemia |
| PCV | 34.1% | 37-55% | LOW | Mild anemia (non-regenerative pattern) |
| TLC (WBC) | 4.4 thou/mm³ | 5.7-14.2 | LOW | Leukopenia - classic E. canis finding |
| RBC | 5.3 mill/mm³ | 5.7-8.8 | LOW | Mild reduction |
| MCV | 64 fL | 60-77 | Normal | Normocytic |
| MCH | 22.0 pg | 20.5-24.2 | Normal | Normochromic |
| MCHC | 34.3 g/dL | 32-36 | Normal | Normochromic |
| Platelet Count | 210 thou/mm³ | 200-500 | Low-Normal | Just above lower limit - watch closely |
| Neutrophils (abs) | 3.12 thou/mm³ | 2.90-12 | Low-Normal | Borderline neutropenia |
| Lymphocytes (abs) | 0.88 thou/mm³ | 0.9-4.7 | LOW | Lymphopenia - typical E. canis |
Key CBC Findings:
- Normocytic, normochromic anemia (Hb 11.7, PCV 34.1%) - typical of anemia of inflammatory/infectious disease in E. canis
- Leukopenia + Lymphopenia - hallmark of acute Ehrlichia canis infection; the organism selectively suppresses white cell production
- Platelet count 210 - borderline low-normal; E. canis classically causes thrombocytopenia; monitor daily as it can drop rapidly
- No blast cells, no toxic changes reported - no evidence of severe sepsis
Overall Picture (CBC + Biochem combined):
Muffin has a moderate acute/subacute E. canis infection with:
- Ehrlichia-driven bone marrow suppression (leukopenia, mild anemia)
- Severe secondary hepatopathy (ALT 401, ALP >1183, Bili 7.9)
- Hypoalbuminemia-driven ascites
- Electrolyte depletion
Complete IV Treatment Protocol
PRIORITY 1 - Anti-Rickettsial (START TODAY, STAT)
Doxycycline IV
- Dose: 5 mg/kg IV every 12 hours
- Preparation: Dilute in 250 mL 0.9% NaCl or 5% Dextrose
- Infusion rate: Over 60-120 minutes (SLOW - never rapid bolus)
- Duration: 28 days total; switch to oral tablet once eating voluntarily
- Expected response: Fever + lethargy should improve within 48-72 hours
PRIORITY 2 - IV Fluids (Careful Fluid Management)
- Fluid of choice: Ringer's Lactate (RL) or PlasmaLyte
- Rate: 40-50 mL/kg/day maintenance
- Do NOT over-fluid: Hypoalbuminemia means excess fluids will worsen ascites
- Add Potassium Chloride (KCl) 0.3 mEq/kg/hr max if hypokalemia develops
- Correct hyponatremia slowly (no faster than 0.5 mEq/L/hr)
PRIORITY 3 - Oncotic Support (for Ascites + Albumin 2.1)
| Option | Dose | Route | Notes |
|---|---|---|---|
| Fresh Frozen Plasma (FFP) | 10-20 mL/kg | IV slow over 4-6 hrs | First choice - also provides clotting factors |
| Human Serum Albumin 25% | 1 g/kg | IV CRI over 4-6 hrs | If FFP unavailable; monitor for reaction |
| Furosemide | 1-2 mg/kg | IV BID | Only after albumin >2.0; helps drain ascites |
PRIORITY 4 - Liver Protection (Critical given ALP >1183, ALT 401, Bili 7.9)
| Drug | Dose | Route | Frequency |
|---|---|---|---|
| N-Acetylcysteine (NAC) | 70 mg/kg loading, then 35 mg/kg | IV slow (dilute in saline) | Q6h x first 24-48 hrs |
| SAMe | 20 mg/kg | PO on empty stomach | Once daily |
| Ursodiol (UDCA) | 10-15 mg/kg | PO | Once daily |
| Milk Thistle (Silymarin) | 50-70 mg/kg | PO | Once daily |
| Vitamin E | 10 IU/kg | PO | Once daily |
| Metronidazole | 10 mg/kg | IV slow | BID (hepatic anti-inflammatory) |
PRIORITY 5 - Supportive & Symptomatic
| Drug | Dose | Route | Frequency | Purpose |
|---|---|---|---|---|
| Maropitant (Cerenia) | 1 mg/kg | SC or slow IV | Once daily | Anti-nausea |
| Omeprazole | 1 mg/kg | IV / PO | Once daily | GI protection |
| Ondansetron | 0.1-0.2 mg/kg | IV slow | Q8-12h if vomiting | Anti-emetic |
PRIORITY 6 - Anemia Management
- PCV 34.1% is mild anemia - does not require blood transfusion yet
- Trigger for transfusion: PCV drops below 20% or patient becomes symptomatic (weakness, collapse)
- With effective doxycycline treatment, bone marrow recovery typically begins within 7-14 days
- Ensure adequate nutritional iron via diet; IV Iron Dextran only if severe iron-deficiency confirmed
PRIORITY 7 - Thrombocytopenia Watch
- Platelet count currently 210 (borderline) - monitor daily
- If platelets drop below 50,000: consider Doxycycline dose optimization + Prednisolone 1-2 mg/kg/day PO (short course for immune-mediated thrombocytopenia component)
- If active bleeding (petechiae, melena, hematuria): Fresh Whole Blood or Platelet-Rich Plasma transfusion
- Avoid NSAIDs entirely - risk of GI bleeding with low platelets + high bilirubin
Daily Monitoring Checklist
| Parameter | Frequency | Alert Threshold |
|---|---|---|
| Temperature | Q6-8h | >39.5°C = infection not controlled |
| Pulse, RR, MM color | Q6-8h | Pale = worsening anemia |
| Abdominal girth | Daily | Increasing = albumin not correcting |
| PCV + Total Solids | Daily | PCV <20% = transfusion trigger |
| Platelet count | Daily | <50K = immune support needed |
| ALT, AST, Bilirubin | Every 3-5 days | Downtrend expected by day 5-7 |
| Albumin | Every 3-5 days | Target >2.5 g/dL |
| Electrolytes | Daily | Correct hyponatremia/hypochloremia |
| BUN/Creatinine | Every 3-5 days | Currently normal - protect kidneys |
| Urine output | Daily | Target >1-2 mL/kg/hr |
Prognosis Summary
| Factor | Assessment |
|---|---|
| Leukopenia + Lymphopenia | Confirms active E. canis - will respond to doxycycline |
| PCV 34.1% | Mild anemia - manageable without transfusion currently |
| Platelets 210 | Borderline - monitor daily, not critical yet |
| ALT 401 / ALP >1183 | Serious hepatopathy but likely reversible with treatment |
| Hypoalbuminemia + Ascites | Will take 2-4 weeks to fully resolve as liver recovers |
Overall prognosis: GUARDED TO FAIR - if doxycycline is started immediately and hepatic support is aggressive, Muffin has a good chance of full recovery. Expect clinical improvement within 48-72 hours of starting IV doxycycline. Liver values may take 3-6 weeks to normalize fully.
Note for attending vet: The leukopenia and lymphopenia are classic for E. canis and confirm the diagnosis clinically. Do NOT delay doxycycline waiting for further confirmation - treat empirically now. A post-treatment PCR test at day 30 is recommended to confirm clearance.
LACTULOSE IN THIS CASE
Finding Sources
Searching the Web
lactulose dose hepatic encephalopathy dog hepatopathy protocol
💊 Lactulose in Muffin's Case - YES, Strongly Indicated
Why Lactulose is Needed for Muffin
Muffin has severe hepatocellular damage (ALP >1183, ALT 401, Bilirubin 7.9 mg/dL). When the liver is this compromised, it cannot detoxify ammonia produced by gut bacteria. Ammonia accumulates in the blood and crosses into the brain, causing Hepatic Encephalopathy (HE) - which manifests exactly as what Muffin is showing: lethargy, dullness, and mental dullness.
So in Muffin's case, the lethargy/dullness may be partly or significantly due to subclinical hepatic encephalopathy - not just the E. canis infection alone.
How Lactulose Works
Lactulose is a non-digestible disaccharide. It is NOT absorbed in the small intestine. In the colon:
- Gut bacteria ferment it → produces lactic acid + acetic acid
- Acidifies the colon → converts free ammonia (NH₃, which is absorbable) into ammonium (NH₄⁺, which is NOT absorbed and gets excreted in stool)
- Osmotic laxative effect → speeds up gut transit, reduces time for bacterial ammonia production
- Reduces colonic bacterial load - fewer bacteria = less ammonia generation
Net result: Significantly less ammonia reaches the bloodstream and brain.
Lactulose Dosing for Muffin (5 kg estimate for dose calculation - confirm actual weight)
| Situation | Dose | Route | Frequency |
|---|---|---|---|
| Maintenance / Prevention of HE | 1-3 mL per 10 kg body weight | PO (oral syrup) | Every 6-8 hours |
| Alternate maintenance dose | 5 mL / 2.5 kg / day | PO | Divided TID |
| If too dull/lethargic for oral | 5-15 mL lactulose diluted 1:3 in water | Rectal enema | Every 8 hours |
| Acute HE crisis (stupor/coma) | 20-60 mL via stomach tube | NG tube | Every 4-6 hours |
Titration rule: Adjust the dose to produce 2-3 soft stools per day - this is the clinical endpoint. More stools = more ammonia being excreted.
Practical Dosing for Muffin (assuming ~10 kg dog)
- Start with: 3-5 mL PO every 8 hours (TID)
- Titrate up until 2-3 soft (not watery) stools/day
- If Muffin is too dull to swallow safely: give as retention enema (10-15 mL lactulose + 30-45 mL water per rectum, hold 15-20 min)
Important Cautions in Muffin's Case
| Caution | Why it Matters for Muffin |
|---|---|
| Avoid overdose/diarrhea | Muffin already has hyponatremia (Na 139) + hypochloremia (Cl 97); osmotic diarrhea from too much lactulose will worsen electrolyte losses |
| Monitor sodium closely | Lactulose-induced diarrhea can cause hypernatremia in dehydrated patients OR worsen existing hyponatremia via fluid shifts |
| Do not give if active vomiting | Risk of aspiration; give rectal route instead |
| Watch for flatulence/bloating | Expected side effect - not dangerous but uncomfortable |
| Combine with Metronidazole | Already in the protocol - metronidazole acts synergistically by further reducing ammonia-producing gut bacteria |
Synergistic Combination Protocol for Muffin's HE Prevention
| Drug | Role | Dose |
|---|---|---|
| Lactulose | Acidifies colon, traps ammonia as NH₄⁺ | 3-5 mL PO TID (titrate to 2-3 soft stools) |
| Metronidazole (already included) | Kills ammonia-producing anaerobes | 10 mg/kg IV/PO BID |
| Low-protein hepatic diet | Reduces ammonia substrate from gut | Hepatic formula diet |
| Ursodiol (already included) | Bile flow improvement, reduces liver inflammation | 10-15 mg/kg PO SID |
Bottom Line
YES - add Lactulose immediately. Given Muffin's bilirubin of 7.9 and severely elevated liver enzymes, subclinical HE is almost certainly contributing to his dullness/lethargy. Lactulose is safe, inexpensive, and directly addresses the ammonia-driven brain toxicity. Start at 3-5 mL PO TID, titrate to 2-3 soft stools/day, and monitor electrolytes daily since Muffin already has sodium/chloride deficits.
HEPAMERZ IV GIVING
Searching the Web
Hepa-Merz L-ornithine L-aspartate IV dose dog hepatic encephalopathy veterinary
💉 Hepa-Merz (LOLA) IV in Muffin - Full Guide
What is Hepa-Merz?
Hepa-Merz = L-Ornithine L-Aspartate (LOLA)
It is a stable salt of two amino acids - L-Ornithine and L-Aspartate. Both are key substrates in the urea cycle and glutamine synthesis pathway - the liver's two main ammonia detoxification routes.
Why LOLA Works in Muffin's Case
Muffin's liver is severely damaged (ALP >1183, ALT 401, Bilirubin 7.9). The compromised liver cannot adequately run the urea cycle to convert ammonia (NH₃) into urea. LOLA works by:
| Mechanism | Where it Works |
|---|---|
| L-Ornithine - direct substrate for urea cycle | Liver (periportal hepatocytes) |
| L-Aspartate - substrate for transamination, boosts glutamate availability | Liver + Muscle + Brain |
| Glutamine synthesis from excess ammonia | Muscle and brain also scavenge ammonia via this route when liver fails |
| Net effect: Ammonia is detoxified faster, blood ammonia drops | Liver + Skeletal muscle |
This is why Muffin is dull/lethargic - ammonia is neurotoxic. LOLA directly lowers blood ammonia and will improve his mentation.
Dosing Protocol for Muffin (Evidence-Based, Veterinary)
Based on the published veterinary clinical trial (Ahn et al., J Vet Sci 2016):
If Muffin has Mild-Moderate HE (dull/lethargic but responsive):
- Dose: 0.616 g/kg/day IV as a constant rate infusion (CRI)
- Duration: 24 hours (Day 1), then reassess
- Preparation: Dilute in 250-500 mL of 0.9% NaCl or 5% Dextrose
- Infuse slowly over 24 hours as CRI
If Muffin has Severe HE (stuporous, unresponsive, seizing):
- Loading: 0.154 g/kg/hour for the first 4 hours
- Maintenance: 0.03 g/kg/hour for the remaining 20 hours
- Maximum daily dose: 1.232 g/kg/day - do NOT exceed
Quick Reference (for ~10 kg dog estimate):
| HE Grade | Dose | Total per day |
|---|---|---|
| Mild-Moderate | 0.616 g/kg/day CRI | ~6.16 g/day |
| Severe | 0.154 g/kg/hr x 4h, then 0.03 g/kg/hr x 20h | ~1.232 g/kg = ~12.32 g/day |
(Confirm Muffin's actual weight to calculate exact dose)
How to Prepare and Administer
- Hepa-Merz IV ampoules typically come as 5g/10mL concentration
- Dilute in 250-500 mL of 0.9% NaCl or 5% Dextrose
- NEVER give as rapid bolus - must be slow infusion
- Max infusion rate: 5g per hour (in humans); in dogs - give over minimum 4-6 hours or as 24-hour CRI
- Do not mix with alkaline solutions or blood products in the same line
Hepa-Merz + Lactulose Together - The Ideal Combination
| Drug | Mechanism | Role |
|---|---|---|
| Hepa-Merz (LOLA) IV | Boosts urea cycle + glutamine synthesis | Detoxifies existing blood ammonia |
| Lactulose PO/rectal | Traps ammonia in gut, speeds transit | Prevents NEW ammonia absorption from gut |
| Metronidazole IV | Kills ammonia-producing gut bacteria | Reduces ammonia production at source |
These three together create a triple-action ammonia reduction strategy and is the most effective approach for Muffin's hepatic encephalopathy.
What to Expect After LOLA IV
| Timeframe | Expected Response |
|---|---|
| 6-12 hours | Blood ammonia starts falling |
| 12-24 hours | Improvement in alertness, mentation |
| 24-48 hours | Muffin should be more responsive, eating better |
| 48-72 hours | Combined with doxycycline effect on E. canis - significant clinical improvement expected |
Monitoring During LOLA IV
- Watch for vomiting - most common side effect; if vomiting occurs, slow the infusion rate
- Avoid doses above 1.232 g/kg/day - higher doses (>1.5 g/kg) caused increased salivation and weight loss in beagles
- Monitor blood glucose - LOLA can affect gluconeogenesis in severe liver failure
- Monitor electrolytes daily (already compromised in Muffin)
Bottom Line for Muffin
✅ Hepa-Merz IV is an excellent addition to the treatment protocol
✅ Start at 0.616 g/kg/day as 24-hour CRI (mild-moderate HE dose)
✅ Combine with Lactulose + Metronidazole for maximum ammonia control
✅ Continue until Muffin is alert, eating, and bilirubin trending down
✅ Can transition to Hepa-Merz oral granules once eating voluntarily for ongoing support
HOW MANY ML IN 7.5 KG DOG
💉 Hepa-Merz IV Dose for Muffin (7.5 kg)
Hepa-Merz IV ampoule = 5g / 10 mL (500 mg/mL concentration)
Mild-Moderate HE Dose (Muffin's current grade - dull/lethargic)
0.616 g/kg/day
| Step | Calculation |
|---|---|
| Dose needed | 0.616 g × 7.5 kg = 4.62 g/day |
| Convert to mL (500 mg/mL) | 4.62 g ÷ 0.5 g/mL = 9.24 mL/day |
| Ampoules needed | ~1 ampoule (10 mL = 5g) per day |
✅ Give 1 full ampoule (10 mL = 5g) diluted in 250 mL Normal Saline, as 24-hour CRI
This is slightly above the calculated dose but within safe range and practically convenient.
Severe HE Dose (if Muffin deteriorates - stuporous/unresponsive)
Maximum: 1.232 g/kg/day
| Step | Calculation |
|---|---|
| Max dose | 1.232 g × 7.5 kg = 9.24 g/day |
| Convert to mL | 9.24 g ÷ 0.5 g/mL = 18.48 mL/day |
| Ampoules needed | ~2 ampoules (20 mL = 10g)/day |
Protocol:
- First 4 hours: 0.154 g/kg/hr × 7.5 kg = 1.155 g/hr = 2.3 mL/hr for 4 hrs
- Next 20 hours: 0.03 g/kg/hr × 7.5 kg = 0.225 g/hr = 0.45 mL/hr for 20 hrs
Quick Summary Card for Muffin (7.5 kg)
| HE Grade | Total Dose | Total Volume | How to Give |
|---|---|---|---|
| Mild-Moderate | 4.62 g/day | ~10 mL (1 ampoule) in 250 mL NS | 24-hr CRI |
| Severe | 9.24 g/day | ~18-20 mL (2 ampoules) in 500 mL NS | 24-hr CRI (loading + maintenance) |
Practical tip: Dilute 1 ampoule (10 mL) of Hepa-Merz into 250 mL Normal Saline and run as slow drip over 24 hours via infusion pump or drip set. Never push as bolus.
