What is the usual cisatracurium dose per kg for adults?
Cisatracurium is dosed by weight (per kg) and by the type of use (intubation/induction vs. maintenance).
For adult neuromuscular blockade:
- Initial (to facilitate intubation): commonly 0.1–0.2 mg/kg IV
- Maintenance (during surgery): commonly 0.03 mg/kg IV given as needed based on clinical response (often using nerve stimulation monitoring)
How do doses change for children?
Pediatric dosing is weight-based too, but typical practice uses:
- Initial: 0.1–0.2 mg/kg IV
- Maintenance: additional doses on clinical response (weight-based titration with neuromuscular monitoring is typical)
What happens if you give too much (or skip monitoring)?
Overdosing can deepen or prolong paralysis and increase the risk of:
- prolonged respiratory muscle weakness requiring extended ventilation
- delayed recovery of neuromuscular function
- difficulty assessing readiness for extubation without objective monitoring (e.g., TOF)
Because cisatracurium effects vary with patient factors, dosing is usually titrated to effect using neuromuscular monitoring rather than by a single fixed regimen.
Is cisatracurium different from atracurium—dose-wise?
Cisatracurium and atracurium are both benzylisoquinolinium neuromuscular blockers, but they are not interchangeable on a mg-for-mg basis. Cisatracurium is generally used at lower milligram doses than atracurium for comparable blockade, so clinicians use cisatracurium-specific dosing guidance.
Any key patient factors that affect dosing per kg?
Even though dosing is per kg, clinicians adjust for situations that can increase sensitivity or prolong blockade, such as:
- severe illness/ICU conditions
- hepatic/renal dysfunction (effects may be prolonged depending on overall condition)
- electrolyte abnormalities
- drug interactions with other agents that depress neuromuscular transmission

If you tell me the setting (OR/ICU), age (adult vs pediatric), and goal (intubation vs maintenance), I can narrow to the most relevant weight-based dose range and timing.
