| Summary: | Abstract Background and purpose: Neuromuscular relaxants are one group of the important drugs in providing good condition for tracheal intubation and operation. Rapid intubation is needed in most situations. Also, most of non- depolarizing relaxants almost have long onset time. We compared the priming with pancrunium and atracurium in providing good and rapid relaxation for tracheal intubation.Materials and Methods: In this prospective study, 65 patients with ASA class I, II were randomized into two groups. Group A received pancrunium and group B received atracurium. Primimg dose was injected as 20% of total dose of relaxant. Twitching response was measured with peripheral nerve stimulator. Intubation was done when % 80 of the twitching response disappeared. The time of total disappearance of twitching response was also recorded.Results: The mean time for the injection of the first dose of relaxant until the time of intubation was 94.47 seconds in group A and 142.9 seconds in group B, which were significantly different (P<0/01). If intubation until the time of twitch response is detained, the time gap of group A will again be less than group B (P<0/01).Conclusion: In priming technique, the time of tracheal intubation with pancrunium is significantly less than atracurium. So, considering the patient's condition and the need for rapid relaxation, pancrunium could be is a better relaxant than atracurium.
