Perioperative Fluid Management in Patients Receiving Major Abdominal Surgery - Effects of Normal Saline Versus an Acetate Buffered Balanced Infusion Solution on the Necessity of Catecholamines for Cardiocirculatory Support, a Randomized Controlled Double-blind Trial

Clinical Trial Summary

Background Intraoperative hypotension is a common problem that significantly contributes to perioperative mortality and morbidity. At the moment the "gold standard" for perioperative fluid management is the so called "goal-directed therapy" that features fluid resuscitation followed if necessary catecholamines if needed for perioperative cardiocirculatory support.

Worldwide the so called "physiological" sodium chlorid (0.9% NaCl) solution is the most often used infusate for perioperative fluid management. Despite its widespread use physiological saline has its major disadvantages such as the increased incidence of metabolic acidosis. Nevertheless catecholamines have their significant side effects as well (eg diminished renal perfusion, increased cardiovascular morbidity) and they therefore should be used with caution.

In a prior study by group members on patients undergoing renal transplantation receiving either physiological saline or an acetate-buffered infusate showed a 50% decrease in catecholamine necessity in the acetate-buffered infusate group. The investigators therefore would like to evaluate the effects of the perioperative fluid choice on the necessity of catecholamine use.

Aim

- Evaluation of the perioperative fluid choice on the necessity of catecholamines for cardiocirculatory support.

- Description of the relationship between perioperative fluid choice and minimal blood pressure as well as the time to catecholamine use and their dosage.

Methods The investigators plan a prospective randomized-controlled trial of all patients undergoing major abdominal surgery at the Vienna General Hospital and Medical University of Vienna. Fluid management and catecholamine use will be based on a oesophageal Doppler -based treatment scheme.

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.
