Lidocaine의 후두분무후 기관튜브삽관이 혈압 및 심박수에 미치는 영향

The effects of endotracheal intubation on the blood pressure and the heart rates after lidocaine spray of the larynx

The effects of endotracheal intubation with laryngoscope on the blood pressure and the heart rates were evaluated in 20patients with oral surgery under general anesthesia. The 20 patients were divided into 2 groups. One group of 10 patients were sprayed on the larynx with 4% lidocaine, 120㎎, 3 minutes before intravenous administration of pentothal sodium and succinylcholine. The results are followings ; 1. The systolic, diastolic, and mean arterial blood pressure were significantly increased in both group after intubation, but the degree of changes in blood pressure was more remarkable in patients without lidocaine spray. 2. The heart rates were significantly increased in both group after intubation and no significant changes were observed in patients with lidocaine spray compared with the control group after intubation. 3. The mean arterial pressure was significantly increased in both group after intubation, but the degree of increase in mean arterial pressure was more significant in patients without lidocaine spray. 4. The heart rates were increased significantly in both group after intubation.
