🛠 Local Anesthetic Maximum Dose by Weight Simulator

This simulator calculates the maximum safe dose of a dental local anesthetic (lidocaine or articaine) based on the patient’s weight.

Weight-Based Maximum Dose Calculation

Placeholder: safe dosing scales linearly with patient weight up to a cap.

  • mg/kg × kg: Formula (Placeholder short caption)
  • Applies: Absolute cap (Placeholder short caption)
  • Lower limit: Pediatric note (Placeholder short caption)
  • Down: Rounding (Placeholder short caption)

How weight sets the ceiling

Placeholder: heavier patients tolerate a higher absolute milligram dose.

Lidocaine vs Articaine Maximum Dose

Placeholder: articaine allows a higher mg/kg ceiling than lidocaine.

  • 4.4 mg/kg: Lidocaine limit (Placeholder short caption)
  • 7.0 mg/kg: Articaine limit (Placeholder short caption)
  • 36 mg: Lidocaine cartridge (Placeholder short caption)
  • 72 mg: Articaine cartridge (Placeholder short caption)

Why the ceilings differ

Placeholder: concentration and metabolism differ between the two drugs.

Number of Cartridges Calculation

Placeholder: max dose divided by per-cartridge mg gives allowed cartridges.

  • 1.8 mL: Cartridge volume (Placeholder short caption)
  • Dose ÷ mg/cart: Division (Placeholder short caption)
  • Floor result: Whole numbers (Placeholder short caption)
  • Round down: Safety margin (Placeholder short caption)

From milligrams to cartridges

Placeholder: clinicians count cartridges, not raw milligrams, chairside.

Cumulative Dose Tracking During Procedure

Placeholder: each injection adds to a running milligram total.

  • mg given: Tracking unit (Placeholder short caption)
  • Per cartridge: Update timing (Placeholder short caption)
  • Max line: Gauge target (Placeholder short caption)
  • Sum applies: Multi-site cases (Placeholder short caption)

Why running totals matter

Placeholder: long procedures can silently approach the safe ceiling.

Toxicity Risk If Maximum Is Exceeded

Placeholder: exceeding the ceiling risks local anesthetic systemic toxicity.

  • LAST: Risk name (Placeholder short caption)
  • CNS symptoms: Early signs (Placeholder short caption)
  • Cardiac events: Severe signs (Placeholder short caption)
  • Stay under max: Prevention (Placeholder short caption)

What happens past the red line

Placeholder: overdose symptoms escalate from tingling to seizure or arrhythmia.

Placeholder: always calculate max dose before starting injections.
