From the registry’s dates

  • Primary completion was expected by Dec 2025, 10 months ago, but the record still lists the study as recruiting.
  • Started Mar 2018; still recruiting 8 years 7 months later.

Study summary

This study compares manual total intravenous anesthesia (TIVA) and target-controll infusion (TCI) in reduction of awareness and dreaming, and the haemodynamical stability during operation. Half of patients will be anesthetized using manual TIVA and other half using TCI.

Read the detailed description

Awareness is possible in TIVA in case of technical failure or prolonged induction phase, TCI technology seems to prevent these events. Total of 80 patients planed for elective neurosurgical brain tumor resection fulfilling the inclusion criteria will be devided into two groups. First half will be anesthetized using TIVA with manual induction and the second half will be anesthetized using TCI. All patients will fulfil Modified Brice Questionnaire one hour after the end of operation.

In context

Intraoperative Awareness

55 studies on the registry are indexed under Intraoperative Awareness; 8 are open to participants now.

This study's planned enrollment of 80 is above the median of 70 across 27 interventional studies indexed under Intraoperative Awareness.

Inclusion criteria

  • Glasgow Coma scale 15
  • ASA Physical Status Classification System I - III
  • planed surgery for brain tumor to 5 hours
  • postoperative awakening

Exclusion criteria

Exclusion Criteria:

  • III, IV
  • abuse of stimulating drugs, grass, alcohol dependence
  • over 40 in females and over 35 in men
  • propofol alergie
  • awake operations
  • postoperative arteficial ventilation

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Study arms

  • Experimental
    Group TCI

    induction and anesthesia will be held by using target-controll infusion

    Procedure: Group TCI

  • Active comparator
    Group TIVA

    induction and anesthesia will be held by manual dosing of propofol and sufentanil

    Procedure: Group TIVA

Interventions

  • ProcedureGroup TCI

    Induction and anesthesia will be done by using Gepth model for sufentanil and Schnider effect model for propofol. Anesthetics will be aplicated using infusion pump Agilia (Fresenius Kabi). Another titration will be according to target value of entropy between 40 and 60 and surgical pleth index below 35.

  • ProcedureGroup TIVA

    Induction of anesthesia will be done by titrating of propofol to the dose of 1.2 mg/kg and sufentanil 5-10 ug according to body weight, maintaining of anesthesia using continuous infusion of propofol 5 mg/ kg/hour and sufentanil 35 ug/hour to reach the target value of entropy between 40 and 60 and surgical pleth index below 35.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2018 (actual). Primary completion is estimated for Dec 2025, 92 months after the start.

Of 18 interventional studies with no phase under Intraoperative Awareness, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 33. This study's planned 92 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 10, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
