고혈압 환자에서 Alfentanil 단독투여 및 Alfentanil과 Esmolol 병용투여가 기관내 삽관에 의한 활력징후의 변동에 미치는 영향

초록

Background: This study was desined to determine the efficacy and clincial usefulness of alfentanil and a combined use of alfentanil and esmolol for blunting hemodynamic responses after tracheal intubation in hypertensive patients who needed a rapid sequence induction. Methods: Group 1 received alfentanil 15μg/kg and group 2 received alfentanil 15μg/kg and esmolol 1 mg/kg intravenously. Thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg were used for the induction of anesthesia. Changes in blood pressure and herat rate were measured during intubation and induction of anesthesia with enflurane-N2O-O2 and vecuronium. Rate pressure products (RPP) was calculated and the frequencies of hypertension, hypotension, tachycardia, bradycardia were measured. Results: In group 1, systolic blood pressure increased significantly at 1, 2 minute and decreased significantly at 4, 5, 10, 15 minute compared to base, and diastolic blood pressure increased significantly at 1 minute and decreased significantly at 4, 5, 10 minute. Heart rate increased significantly at 1, 2 minute. In group 2, systolic blood pressure decrease significantly at 3, 4, 5 minute after tracheal intubation compared to base, and diastolic blood pressure increased at 1 minute and decreased at 4, 5, 10, 15 minute. HR did not change significantly (P ＜ 0.05). Conclusions: In treated hypertensive patients, the use of a combination of alfentanil 15μg/kg and esmolol 1 mg/kg is a useful method to attenuate hemodynamic responses after endotracheal intubation and especially for rapid sequence induction.
