BACKGROUND: a prospective, randomized, double-blind study was designed to evaluate the effects of priming

technique with rocuronium omide for intubation in adult patients undergoing surgical procedures.

METHODS: sixty adult patients of 20-60 years of age with asa-1 physical status posted for surgical procedures were divided in to two

groups. group c received normal saline (2ml) as priming dose and group p received 0.06mg/kg rocuronium (2 ml) as priming dose and after

3 minutes intubating dose group c received 6 mg /kg (5 ml) group p received the 5.4 mg /kg (5 ml) as intubating dose .muscle relaxation was

assessed with nerve stimulator for every 10 seconds and assessed visually for loss of adduction of thumb and disappearance of t1 of train of

four (TOF) stimuli. By this we can note the onset time of intubation (Ti) and intubating conditions were assessed buy cooper et al scoring

system. Any adverse effects were also noted.

RESULTS: The mean onset of intubation time (Ti) in the group P was 52.33�6.79 sec, in the group C was 95.67�11.04 sec ,P value is 0.00 it is

highly signi􀃶cant. Minimum Ti is 80 sec. and maximum Ti is 120 sec. intubation scores as per �cooper et al scoring� were 8 or 9 in both the

groups. There were no incidences of weakness, aspiration, adycardia, ptosis, hypotension, in either of the groups during study

observation.

CONCLUSION: administration of Priming dose of rocuronium before the intubating dose causes the onset of neuromuscular block is rapid

and onset time of intubation is became comparable to that of suxamethonium with excellent intubating conditions and without adverse

effects.
