About this study

Official title: Can Perioperative Goal Directed Hemodynamic Management Reduce the Incidence of Delirium in Older Patients After Major Non-cardiac Surgery?

This study is designed to compare the incidence of postoperative delirium in older patients after major non-cardiac surgery with different perioperative hemodynamic managements: a goal directed hemodynamic management group and a control group

Read the detailed description

Delirium is a common postoperative complication in the elderly. The incidence depends on several factors like the comorbidities of the patient and the type of surgery. Mortality is almost twofold increased after two years for patients suffering from delirium after surgery. Different studies showed that with a multimodal strategy it was possible to reduce the risk of delirium. As several different organ systems are involved in the development of delirium the patient's hemodynamic state seems to be important and is a target point of intervention. Also sufficient perfusion and oxygen delivery is essential in order to avoid impairment of the brain. Recent studies showed that goal directed hemodynamic management can reduce all kind of postoperative complications and improve outcome. However, whether the use of goal-directed hemodynamic management also improves the neurological outcome and reduces the rates of postoperative delirium has not been studied yet.

Aim of this study is to investigate the impact of goal directed hemodynamic management using pulse contour analysis on the incidence of delirium in older patients undergoing non-cardiac surgery, presenting with an intermediate to high risk for delirium. This risk will be assessed preoperatively using a score suggested by Marcantonio.

Patients will be randomized in one of two groups, the goal-directed therapy group and the control group. In the goal-directed therapy (GDT) group hemodynamic management is performed according to an established algorithm obtained by pulse contour analysis. To prove our theory that goal-directed therapy influences the brain by increasing oxygen supply we will use near infrared spectroscopy, which is safe and non-invasive, in our patients. The hemodynamic management is continued in the recovery room or at the intensive care unit according to the mentioned algorithm. The intervention will be terminated as soon as patients fulfil the standard criteria for discharge from recovery room or intensive care.

In the control group hemodynamic management is performed according to heart rate and blood pressure without using extended monitoring.

As the actual incidence has a significant impact on the number needed per group, we are going to perform an interims analysis after 100 included patients according to the O'Brian-Fleming technique. Is the difference of delirium between the two groups significant with an α < 0,002 the study will be finished. Otherwise, the sample size needed per group will be determined assuming an α = 0,048, a two-tailed test and a power of 80%.

UPDATE 19-10-2016:

The interims-analysis of incidences after 100 patients revealed, that 86 patients per group will be needed (α = 0,048, power 80%).

What is being measured

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

  1. Incidence of delirium until day 7 (CAM-Score and clinical diagnosis)

    Delirium according to CAM-Score and clinical diagnosis

    Measured: Before induction of anesthesia until 7 days after surgery

Secondary outcomes (5)
  1. Factors defining delirium

    Duration of delirium, total amount of haloperidol administered

    Measured: 7 days

  2. Short-term cognitive impairment

    Mini Mental State on day 7

    Measured: 7 days

  3. Mortality

    in-hospital mortality, mortality after one year

    Measured: 1 year

  4. Influence on brain oxygen saturation

    Influence of GDT on the frontal oxygen saturation of the brain assessed with Near-InfraRed-Spectroscopy (NIRS)-Monitoring

    Measured: until discharge from recovery room/ICU

  5. Intra- and postoperative Measurements

    Time until discharge, total fluids and amount of catecholamines administered, incidence of overall postoperative complications

    Measured: Until discharge

Questions about this trial

What is this clinical trial studying?

A study testing PulsioflexTM Monitoring in people with Delirium, run by Technical University of Munich at 1 site in Germany.

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 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 8 Apr 2021. 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 Germany. 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?

Incidence of delirium until day 7 (CAM-Score and clinical diagnosis) (time frame: Before induction of anesthesia until 7 days after surgery). 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 NCT01827501, which also lists 2 linked publications.

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 8 Apr 2021.
