Abstract

PURPOSE: To determine the pattern of onset of the intubating dose when given at a monitored target priming block in either phase of the priming drug effect.

METHODS: Sixty consenting ASA I and II patients were premedicated by intramuscular buprenorphine (5 μg·kg

RESULTS: We observed that in spite of significantly variable priming intervals for identical DBSr in two different phases, the onset time of the intubating dose to 0 response was identical in similar DBSr group patients; i.e., at 0.8 DBSr, 65.0±5.2s (group 1)vs 66.0±8.0s (group 2); at DBSr 0.6, 55.2±3.7s (group 3)vs 55.2±4.9s (group 4); and at DBSr 0.5, 43.5±4.8s (group 5)vs 43.5±4.2s (group 6). At 0 twitch response, the intubating conditions were comparable in patients of the six groups.

CONCLUSION: In conclusion, target controlled priming (DBSr) for administration of the intubating dose appears to be a useful double-vision sign to predict the onset of the effect of the intubating dose precisely.
