Neuromuscular Blockade with Cisatracurium
Introduction to Cisatracurium Dosage
- The recommended perfusion dose of cisatracurium for adult patients requiring neuromuscular blockade is 3 mcg/kg/min initially, followed by maintenance at 1-2 mcg/kg/min, titrated to achieve one or two twitches on train-of-four monitoring 1
- Initial bolus dose: 0.1-0.2 mg/kg IV bolus to establish neuromuscular blockade 1
- Metabolism independent of organ function: Cisatracurium undergoes Hofmann elimination and ester hydrolysis, making it suitable for patients with renal or hepatic dysfunction 1
- Predictable recovery: Recovery typically occurs within 34-85 minutes after discontinuation, independent of organ function 1
Monitoring and Adjustment
- Neuromuscular monitoring: Use TOF monitoring to guide dosing 1, 2
- Target: Adjust dose to achieve one or two twitches on TOF monitoring 1
- Assessment frequency: Regular clinical and TOF assessment throughout therapy 1
Pharmacological Properties
- Hemodynamic stability: Cisatracurium produces minimal cardiovascular effects and virtually no histamine release compared to other neuromuscular blocking agents 2
