目的:研究老年患者动脉弹性功能与围术期血压变化的关系。方法:随机选择68例ASA分级Ⅰ-Ⅱ级行全麻手术的老年患者,根据检查所得动脉弹性的结果分为四组,分别是A组(C1、C2均正常),B组(C1异常,C2正常),C组(C1正常,C2异常),D组(C1、C2均异常)。测量其术前血压及全麻诱导8分钟后的血压水平。结果:动脉弹性功能不良的患者其术前MAP较高,且全麻诱导以后血压波动的比例较大。结论:高血压病的老年患者动脉弹性功能普遍降低;动脉弹性下降的老年病人全麻诱导后血压波动较大。
Objective: To study the relationship between arterial elastic function and perioperative blood pressure in elderly patients. Methods: A total of 68 elderly ASA patients with stage I-II general anesthesia were randomly divided into four groups according to the results of arterial elasticity test: group A (C1 and C2 are normal), group B (C1 is abnormal, C2 normal), C group (C1 normal, C2 abnormal), D group (C1, C2 are abnormal). Preoperative blood pressure and blood pressure were measured 8 minutes after induction of general anesthesia. Results: Preoperative MAP was higher in patients with arterial elasticity dysfunction and the proportion of blood pressure fluctuated after induction of general anesthesia. Conclusion: Elderly patients with hypertension generally have reduced arterial elasticity. Blood pressure fluctuates greatly after induction of general anesthesia in elderly patients with decreased arterial elasticity.
