Individualized Perioperative Open-Lung Ventilatory Strategy During One-Lung Ventilation (iPROVE-OLV)

October 1, 2018 updated by: Carlos Ferrando, Fundación para la Investigación del Hospital Clínico de Valencia

Postoperative Complication and Hospital Stay Reduction With a Individualized Perioperative Lung Protective Ventilation During One-lung Ventilation: A Prospective, Multicenter, Randomized Trial

The purpose of this study is to determine whether individualized ventilatory management during one-lung ventilation in patients scheduled for thoracic surgery, combining the use of low tidal volumes, alveolar recruitment maneuvers, individually titrated positive end-expiratory pressure and individually indicated ventilatory support will decrease postoperative pulmonary complications, ICU and hospital length of stay compared to a standardized Lung Protective Ventilation (LPV).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: OLA-iHFNC

Intraoperatively ventilated patients with a tidal volume (VT) of 5-6ml / kg of ideal body weight and respiratory rate to maintain normal carbon dioxide. After intubation, in all patients will be performed an alveolar recruitment maneuver (MRA) and a PEEP titration trial (see Calculation of optimal PEEP). Every 40 minutes will be assessed the need to adjust the level of PEEP by evaluating the dynamic compliance of the respiratory system (Crs). Faced with a decline in Crs> 10% a new MRA and optimal PEEP setting will be assessed.

Postoperatively, high flow oxygen therapy will be individually indicated by evaluating peripheral oxygen saturation.
Procedure: Alveolar recruitment maneuver
To start the Alveolar Recruitment Maneuver (ARM) the ventilatory mode will be changed to pressure-controlled mode (PCV) with 20 cmH2O pressure control ventilation. A respiratory rate (RR) of 15 rpm, inspiration: expiration ratio of 1:1, FiO2 of 0.8 and PEEP of 5 cmH2O. The PEEP level will be increased in 5 cmH2O steps every 10 respiratory cycles, increasing to 15 cycles in the last level of PEEP (20 cmH2O), getting an opening pressure at 40 cmH2O airway (duration of the maneuver: 160 sec.)
Procedure: PEEP Titration Trial
The ventilation mode will then switch back to volume controlled ventilation with the same baseline settings but with 20 cmH2O PEEP level. Then PEEP will be reduced in 2 cmH2O steps each maintained for 5 breaths the level of PEEP with the best (higher) dynamic compliance.
Active Comparator: STD-O2

Intraoperatively ventilated patients with a tidal volume of 5-6 ml / kg of ideal body weightand respiratory rate to maintain normal carbon dioxide, PEEP 5 cmH2O. In this group no recruitment maneuvers or optimal PEEP setting will be performed.

Postoperatively, standard oxygen therapy.
Procedure: Lung protective ventilation
Ventilatory strategy with a PEEP level of 5 cmH2O but without recruitment maneuvers and PEEP titration trial.
