The Effect of Stellate Ganglion Block on Endotracheal Intubation

성상 신경절 차단이 기관내 삽관에 따른 심혈관계 반응에 미치는 영향

The impact of cardiovascular changes occurred by endotracheal intubation is risky for patients with ischemic heart disease, or intracranial pathologic conditions typically impairing cerebral autoregulatory mechanisms. Therefore, multiple approaches have been utilized to limit the impact of intubation and reduce damage of central nervous and cardiovascular systems. These approaches include modifications in intubation technique to diminish circulatory stimuli and pharmacologic modifications of either the sensory afferent path or the circulatory response itself. We tried the stellate ganglion block, a kind of sympathetic block, for the same purpose and evaluated the results. The results of study are as follows, 1) Blood pressure and heart rate increased significantly after intubation as compared with preintubation in both control group and SGB group. 2) The difference of the two groups is not found. We conclude the above method does not control cardiovascular consequences of endotracheal intubation.
