Evaluation of Pcv-aCO2 in the Fluid Treatment of Abdominal Tumor Patients After Surgery

Clinical Study of Central Venous-to-Arterial Carbon Dioxide Difference(Pcv-aCO2) in the Evaluation of Fluid Therapy for Postoperative Patients With Abdominal Cancer

This research will confirm that Pcv-aCO2 is suitable for the guidance of early fluid therapy and the evaluation of the prognosis of patients with abnormal hemodynamics after abdominal tumor surgery, and is expected to be a new monitoring index to improve the therapeutic effect of these patients.

Study Overview

Detailed Description

  1. Confirmed that Pcv-aCO2 is suitable for the guidance of early fluid therapy and the evaluation of the prognosis of patients with abnormal hemodynamics after abdominal tumor surgery, and is expected to be a new monitoring index to improve the therapeutic efficacy of this kind of patients.
  2. Pcv-aCO2 effectively reflected the improvement of tissue and organ microcirculation disorder through the individual goal target treatment to guide the fluid resuscitation in the hemodynamic instability patients.
  3. Research of the correlation between Pcv-aCO2 and the organ function in patients with abnormal hemodynamics after operation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: standard group

The patients with ScvO2 ≥ 70% will receive the conventional fluid therapy.than collect the data of ScvO2 and Pcv-aCO2:

ScvO2≥70%,and furthermore, Pcv-aCO2 is divided into "≤6mmHg" and ">6mmHg"

The patients with ScvO2 ≥ 70% will receive the conventional fluid therapy.
Sham Comparator: control group

The patients with ScvO2 <70% will receive the standardized fluid therapy for 6 hours.than collect the data of ScvO2 and Pcv-aCO2:

ScvO2<70%,and furthermore, Pcv-aCO2 is divided into "≤6mmHg" and ">6mmHg"

The patients with ScvO2 <70% will receive the standardized fluid therapy for 6 hours.
