研究目的:

1. 主要目的:比较麻醉诱导前依据颈动脉矫正血流时间指导补液和常规补液对无痛肠镜老年患者低血压发生率的影响 2.次要目的:比较麻醉诱导前依据颈动脉矫正血流时间指导补液和常规补液对无痛肠镜老年患者不良反应、出院时间等的影响  

Objectives of Study:

1. Primary objective: To compare the effects of fluid replacement guided by carotid artery corrected blood flow time and conventional fluid replacement before anesthesia induction on the incidence of hypotension in elderly patients undergoing painless colonoscopy. 2. Secondary objective: To compare the effects of fluid replacement guided by carotid artery corrected blood flow time and conventional fluid replacement before anesthesia induction on adverse reactions and discharge time in elderly patients undergoing painless colonoscopy.

干预措施:

初始颈动脉FTc<334.95ms,予乳酸钠林格注射液输注15min后再次测定直至颈动脉FTc>=334.95ms;初始颈动脉FTc>=334.95ms直接进行麻醉诱导。

干预措施代码:

Intervention:

The initial carotid FTc was less than 334.95ms. After 15 minutes of infusion of sodium lactate Ringer's injection, it was measured again until the carotid FTc was >=334.95ms. Anesthesia induction is directly performed when the initial carotid FTc is >=334.95ms.
