About this study

Official title: Intraoperative Lung Protective Ventilation in Abdominal Surgery: A Randomized Controlled Study

The purpose of this study is to compare the influence of a lung protective ventilation with conventional ventilation on postoperative complications following major abdominal surgery.

Read the detailed description

Postoperative complications are associated with a significant and quantifiable rate of both morbidity and mortality, increased length of hospital stay and cost of care. Intra-abdominal surgery, especially upper abdominal surgery, is an important risk factor of both pulmonary and extra-pulmonary complications. Up to 15-20% of patients will develop postoperative respiratory failure which may require respiratory support.

Recent data from both experimental and clinical studies suggested that, compared with conventional ventilation using high tidal volume (TV) without positive end-expiratory pressure (PEEP), intraoperative lung protective ventilation using low tidal volume, PEEP and recruitment maneuvers (RM) could reduce postoperative complications. Conventional ventilation promotes sustained cytokine production and could therefore contribute to development of lung injury with in patients with normal lungs. Conversely, lung protective ventilation was found to reduce pulmonary and systemic inflammation.

The primary objective is to compare a lung protective ventilation with conventional ventilation (high tidal volumes without PEEP) during abdominal surgery: 1- Conventional ventilation with TV of 10-12 mL/kg predicted body weight (PBW) without PEEP; 2- Protective lung ventilation with TV of 6-8 mL/kg PBW, PEEP of 6-8 cmH2O and RM.

Our hypothesis is that lung protective ventilation could reduce postoperative pulmonary and extra-pulmonary complications compared with conventional ventilation.

What is being measured

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

  1. Composite endpoint defined as incidence of major postoperative pulmonary (defined as pneumonia, need for noninvasive ventilation or need for invasive ventilation) and extrapulmonary (SIRS, sepsis and septic shock) complications

    Measured: during the first seven days after surgery

Secondary outcomes (10)
  1. Major complications: postoperative hypoxemia, postoperative pneumonia, acute lung injury (ALI), acute respiratory distress syndrome (ARDS), pulmonary embolism

    Measured: at day 15 after surgery

  2. Minor complications : atelectasis, anastomotic leakage, intrabdominal abscess

    Measured: at day 15 after surgery

  3. Other postoperative complications (reintervention, wound abscess, ...)

    Measured: at day 15 after surgery

  4. Systemic level of marker of inflammation (C Reactive protein)

    Measured: at day 15 after surgery

  5. Postoperative complications at day 30 after surgery

    Measured: at day 30 after surgery

  6. Need for ICU admission

    Measured: at day 30 after surgery

  7. ICU length of stay

    Measured: at day 30 after surgery

  8. Hospital length of stay

    Measured: at day 30 after surgery

  9. Mortality

    Measured: at day 30 after surgery

  10. Plasma levels of the soluble form of the receptor for advanced glycation end-products (sRAGE), a marker of alveolar type I cell injury

    Measured: before surgery, during the immediate postoperative period and on day 1, day 3 and day 7 after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Abdominal surgery in people with Protective Lung Ventilation Using: and Low Tidal Volume (6-8 mL/kg Predicted Body Weight), run by University Hospital, Clermont-Ferrand at 1 site in France.

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 4 inclusion and 5 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 5 Oct 2012. 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 France. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Composite endpoint defined as incidence of major postoperative pulmonary (defined as pneumonia, need for noninvasive ventilation or need for invasive ventilation) and extrapulmonary (SIRS, sepsis and septic shock) complications (time frame: during the first seven 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 NCT01282996, 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 5 Oct 2012.
