Abstract

Background: Cisatracurium is one of the cis-cis isomer of atracurium (51W89:1R-cis 1’R-cis atracurium) an intermediate duration non-depolarising neuromuscular blocking drug and is devoid of histamine release. However, 2× ED95 dose of cisatracurium does not provide satisfactory intubating condition. The recommended intubating dose of cisatracurium is 3 ×ED95. The objective of this study was to evaluate and compare duration of action, hemodynamic effects and any adverse effects for different doses of cisatracurium.

Methods: After Institutional Ethical Committee approval and informed patient consent, 80 patients of ASA I and II in the age group of 20-60 years were selected and included in the study. Patients were divided in two groups of 40 each, group A received intravenously 3×ED95 (0.15 mg/kg) loading dose of cisatracurium and group B received intravenously 4×ED95 (0.2 mg/kg) loading dose of cisatracurium.

Results: After induction, MAP and HR shows decrease in both groups but neither statistically nor clinically significant. Better hemodynamic stability and longer duration of action was found in group B compared to group A. No adverse effects noted in both groups.

Conclusions: 4×ED95 dose of cisatracurium provides longer duration of action and more stable hemodynamic status than 3×ED95. No associated signs of histamine release were detected clinically.
