Common Medical Treatment & Pediatric Dosage Guideline PDF for Doctors

For newly graduated MBBS and BDS doctors starting their medical careers in Bangladesh, transitioning from academic learning to clinical practice can be challenging. The “Common Medical Treatment & Pediatric Dosage Guideline” PDF serves as a practical companion, offering concise, user-friendly information on managing common medical conditions across various specialties. This guide is especially valuable for those working in outpatient departments (OPD), wards, or even private chambers, where quick and accurate decisions are a daily necessity.

Purpose
This guideline provides an overview of common medical treatments and pediatric dosing recommendations, supporting safe and effective medication administration in pediatric patients.

Scope
These guidelines are designed for healthcare professionals managing pediatric patients across various clinical settings, ensuring proper dosing and therapeutic approaches.

 

1. General Principles of Pediatric Dosing

• Weight-Based Dosing: Pediatric doses should be calculated based on body weight (mg/kg) or body surface area (BSA), as children’s pharmacokinetics differ from adults.
• Age Considerations: Drug metabolism and excretion can vary by age; neonates, infants, and adolescents require adjusted dosing schedules.
• Monitoring: Regularly monitor for efficacy, adverse effects, and therapeutic drug levels where applicable.

2. Common Medication Categories and Pediatric Dosages

a. Antibiotics

• Amoxicillin: 20-40 mg/kg/day in divided doses every 8 hours, depending on infection severity.
• Ceftriaxone: 50-100 mg/kg/day IV/IM once daily for severe infections.
• Azithromycin: 10 mg/kg on the first day, followed by 5 mg/kg once daily for 4 days.

b. Antipyretics and Analgesics

• Paracetamol (Acetaminophen): 10-15 mg/kg/dose every 4-6 hours as needed (max: 60 mg/kg/day).
• Ibuprofen: 5-10 mg/kg/dose every 6-8 hours (max: 40 mg/kg/day).

c. Antihistamines

• Cetirizine: 0.25 mg/kg once daily for children 6 months to 2 years; 2.5-5 mg once daily for children >2 years.
• Chlorpheniramine: 0.35 mg/kg/day in divided doses every 4-6 hours.

d. Bronchodilators

• Salbutamol (Albuterol): 0.1-0.2 mg/kg/dose via inhalation every 4-6 hours.
• Ipratropium Bromide: 250 mcg via nebulizer every 6-8 hours for children <12 years.

e. Anticonvulsants

• Phenytoin: 5 mg/kg/day in divided doses every 8 hours; maintenance may be adjusted based on serum levels.
• Valproic Acid: 10-15 mg/kg/day initially, increasing by 5-10 mg/kg/week (max: 60 mg/kg/day).

f. Antiemetics

• Ondansetron: 0.15 mg/kg IV or 2-4 mg orally before chemotherapy; may be repeated every 8 hours if needed.
• Domperidone: 0.25-0.5 mg/kg/dose 3-4 times daily before meals.

3. Emergency Medications

Adrenaline (Epinephrine)

• Anaphylaxis: 0.01 mg/kg (1:1,000 solution) IM every 5-15 minutes as needed.
• Cardiac Arrest: 0.01 mg/kg (1:10,000 solution) IV every 3-5 minutes.

Diazepam

• Seizures: 0.3-0.5 mg/kg IV/rectally; may repeat once after 10-15 minutes if seizures persist.

4. Fluid and Electrolyte Management

Maintenance Fluid Calculation (Holliday-Segar Method)

• 4-2-1 Rule:
  • 4 mL/kg/hour for the first 10 kg of body weight
  • 2 mL/kg/hour for the next 10 kg
  • 1 mL/kg/hour for each additional kg above 20 kg

Oral Rehydration Solution (ORS)

• For mild to moderate dehydration: 50-100 mL/kg over 4 hours, then reassess.

5. Common Pediatric Emergencies and Management

Asthma Exacerbation

• First-Line Treatment: Salbutamol nebulization (0.15 mg/kg/dose) every 20 minutes for 1 hour, then adjust based on response.
• Steroids: Prednisolone 1-2 mg/kg orally for 3-5 days.

Hypoglycemia

• Immediate Treatment: 0.5-1 g/kg dextrose 10% IV bolus, followed by a glucose infusion if needed.
• Maintenance: Adjust based on blood glucose levels, monitoring every 30 minutes.

6. Documentation and Follow-Up

• Accurate Recording: Document drug name, dosage, route, timing, and any adverse effects.
• Follow-Up: Reassess treatment response and modify dosages or drugs as needed.
