Detailed Description

Introduction: remifentanil's optimal dose for children intubation without neuromuscular blockade is unknown.

Method: phase IV adaptative trial using Dixon's up-and-down method for modeling remifentanil's dose-response curve for adequate intubation conditions as defined by previous studies. Remifentanil doses starting from 2mg/kg will be infused before intubation. When a success occurs next patient's dose will be decreased by 0.25mg/kg/h. When a success does not occur the next patient's dose will be increased by 0.25mg/kg/h. Intubation will be considered adequate if patient does not cough, does not move, if vocal cords are open, if larigocsocpic Cormack grade I or II.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Study arm
There is a single study arm. Remifentanil will be infused before intubation. The first patient will receive remifentanil 2mg/kg. If a success occurs the next patient's dose will be decreased by 0.25mg/kg and else it will be increased by 0.25mg/kg. This rule will apply recursively as Dixon's Up-And-Down Method.
