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.
