Interventions:

组别:

试验组

样本量:

88

Group:

Experimental group

Sample size:

干预措施:

VC-CI 导向输液:IVC-CI > 40%,5 ~10 min内输 3 ml/kg,输液完成后 5 min 再次测量 IVC-CI;IVC-CI20% ~40%,给予 4 ml/kg·h ;IVC-CI≤20%,给予2kml/kg·h。

干预措施代码:

Intervention:

Fluid administration protocol guided by IVC-CI: If IVC-CI > 40%: Administer a 3 ml/kg bolus over 5-10 minutes. Re-measure IVC-CI 5 minutes after completion of the fluid bolus. If IVC-CI is 20% to 40%: Administer a maintenance infusion at 4 ml/kg/h. If IVC-CI <= 20%: Administer a maintenance infusion at 2 ml/kg/h.

Group:

Control group

Sample size:

干预措施:

与试验组相同时间点测量IVC-CI并记录,但不依据IVC-CI输液,常规传统以4 ml·kg-1·h-1的速度输乳酸林格钠。

干预措施代码:

Intervention:

IVC-CI was measured and recorded at the same time point as the experimental group, but the infusion was not based on IVC-CI. Lactated Ringer's sodium was infused at the rate of 4 ml·kg-1·h-1 conventionally.
