Goal-directed Intraoperative Fluid Therapy in High-risk Surgery

Status Completed

Clinical Trial Summary

This study is aim to assess the effect of goal-directed intraoperative fluid therapy on patient's postoperative incidence rates of complications, length of hospitalization and hospitalization cost.

This is an observational study followed cohort study design, due to the two therapies were not randomized assigned to the two cohorts. The details are described as follow.

Clinical Trial Description

The study will be conducted in patients undergoing either elective laparotomy of gynecological malignancies or elective major orthopaedic surgery under prone position in Peking Union Medical College Hospital. The study included two stages.

In the first stage, one cohort of 300 participants with conventional fluid therapy will be involved, in which 150 patients will be selected with laparotomy of gynecological malignancies and150 patients will be selected with orthopedic surgery. All the participants in this stage will follow conventional fluid therapy to direct the amount of intraoperative fluid. Specifically, the fluid will be administered based on the principle crystalloid solution (colloid solution =2-3:1). The total volume of fluid will be adjusted in accordance with blood pressure, heart rate and urine output of each patient. It is a standard procedure in Peking Union Medical College Hospital. Then, the incidence of postoperative complications of each group will be recorded. In addition, sample size will be estimated based on above study's results (estimated 100 participants).

In the second stage, goal-directed therapy will be applied to another cohort of 300 participants, in which 150 patients undergoing laparotomy of gynecological malignancies and 150 patients undergoing orthopedic surgery. Specifically, the fluid will be administered based upon real-time monitoring stroke volume variation and cardiac output achieved by the Flo-Trac monitoring system. The incidence of postoperative complications of each group will be recorded. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
