Background: Neuromuscular-blocking drugs block neuromuscular transmission, causing paralysis of the affected skeletal muscles. In clinical use, neuromuscular block is used adjunctively to anesthesia to produce paralysis, first to paralyze the vocal cords, and permit intubation of the trachea, and second to optimize the surgical field by inhibiting spontaneous ventilation, and causing relaxation of skeletal muscles. Patients and Methods: This was a prospective, randomized study registered in Clinical Trials Registry of India (CTRI/2019/04/018580). We included 100 patients divided into two groups of 50 each. Group A received atracurium (0.5 mg/kg), whereas Group B received cisatracurium (0.15 mg/kg). Efficacy of both the drugs was compared in terms of onset of action, duration of action, duration of recovery, hemodynamic conditions during and after intubation, and signs of histamine release in both the drugs. Results: Mean duration of 25% recovery from the reversal in the atracurium group was 32.4 ± 1.90 min which was significantly less as compared to 49.46 ± 1.86 min of cisatracurium group (P < 0.001). The mean duration of recovery from the reversal in cisatracurium group was 2.18 ± 0.82 min which was significantly more as compared to 1.8 ± 0.75 min of atracurium group (P = 0.02). Conclusion: Cisatracurium in a dose of 0.15 mg/kg had a faster onset and duration of action than atracurium 0.5 mg/kg. At this dose, cisatracurium provides optimal intubating condition, rapid neuromuscular blocking with longer duration of action, stable hemodynamic status, no signs of histamine release clinically, and without any residual muscle paralysis compared to atracurium.
