Mechanical Ventilation in Surgical Patients (MEET VENUS)

May 25, 2026 updated by: Gianmaria Cammarota, Azienda Ospedaliera SS. Antonio e Biagio e Cesare Arrigo di Alessandria

Management of Mechanical Ventilation During Surgery: an International, Multicenter, and Observational Data Registry

This is an investigator-initiated, international, multicenter, prospective, cross-sectional study that aims to 1) describe the incidence and types of postoperative pulmonary complications (PPCs), 2) describe patient demographics, baseline characteristics, and intraoperative ventilation management, 3) describe the occurrence of intraoperative adverse events (IAEs), and 4) their associations with PPCs, 5) assess the practice of intraoperative mechanical ventilation.

Patients will be eligible for participation if: 1) adult and 2) receiving intraoperative ventilation during general anesthesia for surgery. Patients receiving ventilation outside of an operating room as well as patients receiving intraoperative ventilation during extracorporeal life support will be excluded

Detailed Description

This is an investigator-initiated, international, multicenter, prospective, cross-sectional study The here proposed study aims to 1) describe the incidence and types of postoperative pulmonary complications (PPCs), 2) describe patient demographics, baseline characteristics, and intraoperative ventilation management, 3) describe the occurrence of intraoperative adverse events (IAEs), and 4) their associations with PPCs, 5) assess the practice of intraoperative mechanical ventilation.

Patients will be eligible for participation if: 1) adult and 2) receiving intraoperative ventilation during general anesthesia for surgery. Patients receiving ventilation outside of an operating room as well as patients receiving intraoperative ventilation during extracorporeal life support will be excluded.

The primary endpoint is to report the number of patients with PPCs occurring in the first 5 postoperative days. As secondary endpoint, the practice of mechanical ventilation in patients undergoing general anesthesia for surgery will be ascertained including key intraoperative ventilator characteristics and respiratory system mechanics. Other secondary endpoints will include: incidence and type of IAEs; postoperative complications other than PPCs in the first 5 postoperative days; intensive care unit (ICU) admission and length of stay, hospital length of stay, and hospital mortality on day 28.

Participating hospitals have the flexibility to choose a specific time period for data collection, but it is imperative that this process occurs within 8 weeks from receiving approval by the local Ethics Committee. Furthermore, each participating center will conduct data collection during a predetermined 7-day period. Local investigators will capture data in an electronic case recording form, including patient demographics and baseline characteristics, intraoperative ventilator settings and ventilation parameters, and outcomes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Postoperative pulmonary complications (PPCs)
Time Frame: within 5 days after surgery
Incidence and type of PPCs
within 5 days after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
