Experimental Group 1(IVC-CI)

Sample size:

干预措施:

术前测量患者下腔静脉塌陷指数(IVC-CI),并分组:1.若IVC-CI≥40%,麻醉诱导前15min 内给予5ml/kg的液体冲击,再评估IVC-CI,若IVC-CI≥40%继续给予前次1/2 的液体剂量,重复上述操作直至IVCCI<40%,10分钟后开始麻醉诱导;2.IVC-CI<40%,诱导前以4ml /kg·h 的速度补液,10分钟后开始麻醉诱导;

干预措施代码:

Intervention:

Group guided by inferior vena cava ultrasound (IVC-CI) for fluid resuscitation: Measure the patient's inferior vena cava collapse index (IVC-CI) before surgery and group as follows: 1. If IVC-CI >= 40%, administer a 5ml/kg fluid bolus within 15 minutes before anesthesia induction, then re-evaluate IVC-CI. If IVC-CI >= 40%, continue to administer half of the previous fluid dose, repeat the above steps until IVCCCI < 40%, and begin anesthesia induction 10 minutes later; 2. If IVC-CI < 40%, administer fluids at a rate of 4ml/kg·h before induction, and begin anesthesia induction 10 minutes later;

干预措施代码:

Intervention:

Measure the patient's internal jugular vein collapse index (IJV-CI) before surgery and group as follows: 1. If IJV-CI >= 40%, administer a 5ml/kg fluid bolus within 15 minutes before anesthesia induction, then re-evaluate IJV-CI. If IJV-CI >= 40%, continue to administer half of the previous fluid dose, repeat the above steps until IJVCI < 40%, and begin anesthesia induction after 10 minutes; 2. If IJV-CI < 40%, administer fluids at a rate of 4ml/kg·h before induction, and begin anesthesia induction after 10 minutes;
