About this study

Official title: Use of Heart-lung Interaction Parameters to Predict Haemodynamic Tolerance to the Open Lung Approach With Individualised PEEP During Invasive Mechanical Ventilation in the Operating Room

This is an observational, prospective, single-centre study that will focus on patients undergoing major non-cardiac surgery requiring invasive mechanical ventilation and invasive blood pressure monitoring Hypotheses: A positive TVC (tidal volume challenge) prior to the recruitment manoeuvre (RM) predicts a decrease in CI within 5 minutes of individualised PEEP establishment of at least 10%.

  1. T0: Moment prior to the start of tidal volume challenge. Baseline values
  2. T1: After tidal volume challenge, moment priorate the start of the recruitment manoeuvre (RM). Mostcare and ventilator values. From this moment on, the parameters obtained from Mostcare will be analysed continuously (minute by minute) until 15 minutes after establishing the individualised PEEP.
  3. T2: At minute 5 of establishing individualised PEEP. All parameters derived from basic monitoring, Mostcare, and ventilator monitoring shall be monitored and recorded. Record whether any fluid bolus has been administered.

This is an observational, prospective, single-centre study that will focus on patients undergoing major non-cardiac surgery requiring invasive mechanical ventilation and invasive blood pressure monitoring

Lung recruitment manoeuvres (RM) are performed to prevent collapsed lung parenchyma from compromising oxygenation. In order to open collapsed lung areas, intrathoracic pressure needs to be raised and this may have haemodynamic repercussions especially in patients with an overt or latent hypovolaemic state. Parameters such as stroke volume variation (SVV) or pulse pressure variation (PPV) reflect to some extent the heart-lung interaction and have been used as predictors of fluid responsiveness by exploiting this principle to detect preload-dependent patients. The tidal volume challenge (TVC) uses the same principle of heart-lung interaction with better results. TVC can be a predictor of haemodynamic tolerance to RM + individualised PEEP.

Hypotheses: A positive TVC prior to the recruitment manoeuvre (RM) predicts a decrease in CI within 5 minutes of individualised PEEP establishment of at least 10%.

Data will be collected in the surgical area. Demographic and clinical parameters will be collected from the patient's clinical history, respiratory parameters obtained from the respirator, haemodynamic parameters obtained from the Mostcare device, oxygenation parameters before and after a recruitment manoeuvre.

If the patient meets all inclusion criteria and none of the exclusion criteria, he/she will be included for data collection. If he/she benefits from a recruitment manoeuvre (air-test + clinical indication), which will be assessed by clinical indications, he/she will be entered into our study. All measurements will be taken under stable haemodynamic conditions (HR and MAP should be stable and with +-10% variation for 1 min prior to measurements), without administration of vasoactive drugs or influential surgical aggression at that time.

When the recruitment manoeuvre (RM) is performed, we will monitor all the variables by setting the following time points:

  1. T0: Moment prior to the start of recruitment manoeuvre. All the variables described (Mostcare, ventilator, basic monitoring) and the administration of fluids prior to the manoeuvre shall be monitored. To avoid artefacts on the arterial waveform, a fast-flush test and assessment of dP/dtMAX should always be performed. Patients who do not have optimal arterial waveform morphology at this point will be excluded.
  2. T1: At minute 1 after starting the VTC, the parameters derived from the basic monitoring and the Mostcare will be checked. From this moment on, the parameters obtained from Mostcare will be analysed continuously (minute by minute) until 15 minutes after establishing the individualised PEEP.
  3. T2: At minute 5 of establishing individualised PEEP. All parameters derived from basic monitoring, Mostcare and ventilator monitoring shall be monitored and recorded. Record whether any fluid bolus has been administered.

What participants receive

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

  • Tidal Volume ChallengeDiagnostic test

    The tidal volume challenge is a fluid response test that consists of increasing the tidal volume from 6 ml/kg to 8 ml/kg for 1 minute and evaluating PPV. If PPV increases by more than 2%, it is considered positive, otherwise it will be negative.

  • Recruitment maneuver obtaining individualised PEEPProcedure or surgery

    The alveolar recruitment maneuver is a well-studied procedure to open the lung during invasive mechanical ventilation, allowing us to achieve the best PEEP for that lung, which is individualised PEEP.

Study groups in NCT06123039
Study groupRoleWhat they receive

NEGATIVE Tidal Volume ChallengePopulation with a negative result in the tidal volume challenge. That is, not enough increase in PPV.

What is being measured

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

  1. Tidal volume challenge as a predictor of hemodynamic response to Open Lung Approach

    To describe the relationship between baseline Tidal Volume Challenge and the difference in baseline and 5-minute CI (cardiac index) after Recruitment Maneuver with individualised PEEP (Open Lung Approach). We consider a 10% decrease in CI as clinically significant.

    Measured: At minute 5 after recruitment maneuver

Secondary outcomes (4)
  1. Heart-lung interactions to predict hemodynamic response to Open Lung Approach

    To describe the relationship between baseline Heart-lung interactions (Changes in Pulse pressure variation with Tidal Volume Challenge, Pulse pressure variation at 6 or 8 ml/kg of tidal volume and Stroke Volume variation at 6 or 8 ml/kg of tidal volume) and the difference in Cardiac Index at baseline and at 1 and 5 minute after Recruitment Maneuver with individualised PEEP acquisition (Open Lung Approach).

    Measured: 5 minutes after RM

  2. Heart lung interactions as predictors of hemodynamic tolerance to Open Lung Apprach assessed by Mean Arterial Pressure

    To describe the relationship between baseline Heart-lung interactions (Changes in Pulse pressure variation with Tidal Volume Challenge, Tidal Volume Challenge, Pulse pressure variation at 6 or 8 ml/kg of tidal volume and Stroke Volume variation at 6 or 8 ml/kg of tidal volume) and the difference in Mean Arterial Pressure at baseline and at 1 and 5 minutes after Recruitment Maneuver with individualised PEEP acquisition (Open Lung Approach).

    Measured: For 5 minutes from the recruitment maneuver

  3. CI and MAP correlation for assessing hemodynamic impact of Open Lung Approach

    To assess whether changes in CI are correlated with changes in Mean Arterial Pressure (MAP) before and after the RM with individualised PEEP (Open Lung Approach).

    Measured: For 5 minutes from the recruitment maneuver

  4. Heart-lung interactions as predictors of hemodynamic tolerance to Open Lung Approach over time

    To describe the relationship between baseline heart lung interactions (TVC and Pulse pressure Variation) and the difference in CI (cardiac index), stroke volume variation and Mean arterial Pressure at baseline and the 15 minutes following RM with individualised PEEP acquisition (Open Lung Approach).

    Measured: For 15 minutes from the recruitment maneuver

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?

Tidal volume challenge as a predictor of hemodynamic response to Open Lung Approach (time frame: At minute 5 after recruitment maneuver). 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 NCT06123039, which also lists 58 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.
