About this study

Official title: Can Biomarkers Aid in the Prediction of Postoperative Pain and Circulatory Instability After Major Abdominal Surgery? A Prospective Observational Study

Patients undergoing major surgery are exposed to extensive damage of tissues, which induces widespread activation of the inflammatory system, called 'systemic inflammatory response syndrome' (SIRS).This activation of the inflammatory system may induce instability of the heart and respiration in the postoperative period. The degree of physiologic response to postoperative SIRS as well as the degree of postoperative pain differ between patients. Therefore, patients undergoing anesthesia and major surgery are treated in a 'post anesthesia care unit' (PACU) after end of surgery.Admittance to a PACU is expensive. The time patients need to stay in a PACU after major surgery has not been extensively studied, and more appropriate tools for prediction of length of stay are needed.

The main aim of this study is to assess whether clinical observations, inflammatory biomarkers or genetic markers may aid in the prediction of physiological instability and/or pain after major surgery. Such predictors would help clinicians planning the length of PACU-stays.

What participants receive

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

Study groups in NCT02563652
Study groupRoleWhat they receive
Major abdominal surgeryPatients undergoing major abdominal surgery (laparotomy). Surgical procedures considered for inclusion include, but are not restricted to, procedures such as gastrectomy, pancreatic surgery, liver resection, open prostatectomy, colonic surgery, radical cystectomy with ileal conduit, open nephrectomy and vascular abdominal aortic surgery.

What is being measured

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

  1. Time to established circulatory stability for > 2 hours [Time to event outcome]

    Circulatory stability will be assessed by applying a multi-state statistical model, where any state changes are measured at an hourly basis. The model will include variables reflecting the circulatory state of the patient, including heart rate, systolic blood pressure (or MAP) and lactate, which will be assessed together with the measures needed to maintain them, such as the amount of fluid given (ml per hour) and the extent of vasopressor (i.e. norepinephrine). The main outcome variable will be the time needed to reach the state of 'stable without intervention for more than two hours. To be classified in this state, the systolic blood pressure must be > 100 mmHg, the heart rate between 40 and 110, the patient must be off vasopressor and has a fluid requirement of less than 250 ml/hour.

    Measured: 48 hours

  2. Time to reaching a state of no or mild pain problem for > 2 hours [Time to event outcome]

    This outcome will be reached when the patient has a numeric rating score (NRS) with respect to pain of < 4 and the opioid consumption is less than 5 mg morphine equivalents per hour.

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Systemic Inflammatory Response Syndrome, run by St. Olavs Hospital at 2 sites in 2 countries.

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 2 inclusion and 3 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 14 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy, Norway. 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?

Time to established circulatory stability for > 2 hours [Time to event outcome] (time frame: 48 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 Nov 2018.
