About this study

Official title: Pathophysiology of Perioperative Fluid Management in Patients Un-dergoing High Risk Emergency Laparotomy, a Prospective Descriptive Cohort Study

Pathophysiology of perioperative fluid management in patients undergoing emergency laparotomy.

Read the detailed description

In critically ill patients and patients undergoing major surgery, the combination of internal fluid shifts and fluid retention resulting in extravascular fluid accumulation and postoperative organ dysfunctions, complicates perioperative fluid management and influences patient outcome.

Changes in extravascular volume after surgery have been much debated, studies in major surgery suggest that extracellular volume expansion may correlate with intraoperative fluid administration, while other studies show the intravascular volume to be decreased after surgery.

Difficulty in obtaining accurate measurements of the fluid phases is recognized and despite years of research, perioperative extravascular volume changes have not been clarified in acute high-risk abdominal (AHA) surgery. It is essential to be able to identify and characterize the transition from necessary fluid resuscitation to harmful fluid volume accumulation, intra- as well as extravascular.

The present study seeks to investigate the perioperative fluid status and fluid shifts in patients undergoing AHA surgery, specifically focusing on intra- versus extra-vascular fluid status in patients with intestinal obstruction versus intestinal perforation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT03997721
Study groupRoleWhat they receive
PerforationPatients undergoing primary emergency laparotomy/laparoscopy due to suspicion of intestinal perforation or ( small intestine, large intestine), perforated ventricular or duodenal ulcer
ObstructionPatients undergoing primary emergency laparotomy/laparoscopy due to suspicion of intestinal obstruction
Anasomotic leakPatients undergoing primary emergency laparotomy/laparoscopy due to suspicion of anastomotic leak following elective surgery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The fluid distribution, during the early perioperative period (≤ 5 days), in patients with intestinal perforation versus intestinal obstruction versus postoperative complications with peritonitis.

    Intra vs. extra vascular. Stroke volume assessment, Bioimpedance measurements

    Measured: perioperative period

Secondary outcomes (5)
  1. Impact of fluid distribution/fluid overload on preload dependency.

    Measured: Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day

  2. Impact of fluid distribution/fluid overload on peripheral perfusion.

    Measured: Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day

  3. Correlation between fluid balance just prior to surgery and intraoperative need for vasopressor/inotropes administration.

    Measured: Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day

  4. Evaluate the relationship between fluid overload and mortality rate in patients undergoing emergency laparotomy.

    Measured: Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day

  5. Association between pre- to postoperative changes in volume status and perioperative fluid volume administration, in patients with intestinal perforation versus intestinal obstruction versus postoperative complications with peritonitis.

    Measured: Preoperatively, 6 hours postoperatively and on first, third and fifth postoperative day

Questions about this trial

What is this clinical trial studying?

An observational study of Intestinal Obstruction and Intestinal Perforation, run by Copenhagen University Hospital, Hvidovre at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The fluid distribution, during the early perioperative period (≤ 5 days), in patients with intestinal perforation versus intestinal obstruction versus postoperative complications with peritonitis. (time frame: perioperative period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03997721, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2022.
