Arm Description

End expiratory lung volume (EELV) will be measured at each step during a 5-step decremental PEEP trial. PEEP will be ≥5 cmH2O and set to ensure the maximum recruitment observed in the PEEP trial, with a maximum permitted PPLAT of 30 cmH2O. In particular, when interpreting the results of the PEEP trial, recruitment-to-inflation (RI) ratio calculated across two adjacent PEEP levels will drive PEEP setting. RI≥1.5 between two PEEP levels will lead to the setting of the higher PEEP. RI<0.5 will lead to the setting of the lower PEEP value. In case of RI≥0.5 and <1.5, the choice among two adjacent PEEP levels will be left to the attending physician, who will indicate the set PEEP in order to best balance between the commitment of limiting total, static and dynamic strain and of optimizing oxygenation and haemodynamics.

PEEP set so that the plateau pressure is within the following limits: 28 cmH2O≤Pplat≤ 30 cmH2O

Outcomes

Primary Outcome Measures

Composite clinical outcome that incorporates ICU mortality, 60-day ventilation-free days (VFD60) and the Area Under the Curve of the InterLeukin-6 serum concentration (IL6AUC) during the first 72 hours of observation
Composite clinical outcome that incorporates ICU mortality, 60-day ventilation-free days (VFD60) and the Area Under the Curve of the InterLeukin-6 serum blood cytokine concentration (IL6AUC) during the first 72 hours of observation. Every participant in the treatment group will be compared with every participant in the control group and assigned a score resulting from each comparison. Mortality takes precedence over VFD60, which takes precedence over IL6AUC. Two VFD60's will be considered different for the purpose of scoring only if their difference is larger than 5 days. Similarly, two IL6AUC's measurements will be considered different only if their difference exceeds 10% of the smaller of the two. These individual-comparison scores are added up to obtain the cumulative score primary endpoint for each participant. The sum of scores for patients in the treatment group is compared to the sum of scores of subjects in the control group and compared according by use of Mann-Whitney test

5. Study Description

Brief Summary
During the acute respiratory distress syndrome (ARDS), patients' response to positive end-expiratory pressure (PEEP) is variable according to different degrees of lung recruitability. The search for a tool to individualize PEEP on the basis of patients' individual response is warranted. Measurement of end-expiratory lung volume (EELV) by the nitrogen washin-washout technique, bedside available from recent ICU ventilators, has been shown to reliably estimate PEEP-induced alveolar recruitment and may therefore help titrate PEEP on patient's individual requirements. The authors designed an open-label, multicenter, randomized trial to test whether an individualized PEEP setting protocol driven by EELV may improve a composite clinical outcome in patients with moderate-to-severe ARDS.
Detailed Description
ARDS patients with a PaO2/FiO2 ratio equal or below 150 mmHg (during mechanical ventilation with PEEP 5 cmH2O) will be enrolled within 24 hours from endo-tracheal intubation. To standardize lung volumes at study initiation, all patients will undergo mechanical ventilation with tidal volume set at 6 ml/kg of predicted body weight and PEEP set to obtain a plateau pressure within 28 and 30 cmH2O for thirty minutes (Express PEEP). Afterwards, a 5-step decremental PEEP trial will be conducted (Express PEEP to PEEP 5 cmH2O), and EELV will be measured at each step. PEEP-induced alveolar recruitment will be calculated for each PEEP range as the difference between PEEP-induced change EELV and the predicted increase in lung volume due to PEEP (PEEP-induced overdistension, equal to the product of respiratory system compliance and PEEP change). Patients will be then randomized to receive mechanical ventilation with PEEP set according to the optimal recruitment observed in the PEEP trial (IPERPEEP arm) trial or according to the Express strategy (Control arm, PEEP set to achieve a plateau pressure of 28-30 cmH2O). In both groups, tidal volume size, the use of prone positioning and neuromuscular blocking agents will be standardized. Primary endpoint of the study is a composite clinical outcome incorporating in-ICU mortality, 60-day ventilator free days and the area under the curve of serum Interleukin 6 over the course of the initial 72 hours. Primary and secondary endpoints will also be analyzed in subgroups, as defined below: ∆EELV5-16/FRC ≥ 73% [18] during the PEEP trial ∆EELV5-16/FRC < 73%[23] during the PEEP trial Recruitment-to-inflation ratio (RI) ≥ 1 and <1 across the range between the lowest and highest PEEP tested during the PEEP trial P/F ratio<100 mmHg at study inclusion IL-6>400 pg/ml at study inclusion

Intervention Name(s)
Invasive Mechanical ventilation
Intervention Description
Volume-control ventilation with tidal volume will be set at 6 mL/Kg of predicted body weight, respiratory rate to maintain pH>7.30 and PaCO2<50 mmHg and FiO2 will be set to achieve a SpO2>88-95%. In case of hypercapnia with Ph<7.30 despite a respiratory rate=30-35, an increase in tidal volume up to 8 ml/kg will be allowed. In both groups, the assigned ventilation protocol will be followed for a minimum of 72 hours from randomization and any time fully controlled ventilation is deemed necessary by the attending physician up to 14 days from randomization. After 14 days from randomization, PEEP will be set according to the clinical practice of each institution. After 72 hours from the study protocol, the PEEP setting protocol according to the assigned treatment will be resumed at any time within 14 days from enrolment if fully controlled ventilation is established, according to the decision of the attending physician in charge.
Intervention Type
Drug
Intervention Name(s)
Neuromuscular Blocking Agents
Intervention Description
All patients will receive NMBA for 48 hours after the enrolment. The decision to stop NMBA administration after 48 hours will be left to the attending physician, but muscle paralysis will be strongly encouraged if PaO2/FiO2 ratio remains lower than 80-100 mmHg. NMBA administration will be resumed anytime deemed necessary by the attending physician.
Intervention Type
Procedure
Intervention Name(s)
Prone positioning
Intervention Description
Prone positioning will be used in all enrolled patients as a standard of care: the decision about the timing and the duration of prone position sessions will be left to the attending physician and the time spent by the patient in the prone and in the supine position will be recorded: PEEP will be re-set according to the protocol of the allocated treatment anytime patient's position is changed.
Intervention Type
Procedure
Intervention Name(s)
Resume of spontaneous breathing
Intervention Description
Assist/control and assist ventilation will be allowed after 72 hours from the enrolment if deemed appropriate by the attending physician. During spontaneous breathing, PEEP will be set according to the decision of the attending physician and the practice of each institution: however, in order to standardize the treatments, moderate PEEP (10-15 cmH2O) will be encouraged in case of moderate hypoxemia (PaO2/FiO2<150 mmHg) in control group, while PEEP close to the value set during controlled ventilation according to the treatment protocol but <15 cmH2O will be suggested in the intervention group. During assist/control and assisted ventilation, PEEP will never be higher than the last PEEP set according to the assigned protocol during controlled ventilation. Fully controlled mechanical ventilation will be resumed any time during the study period if the patient meets the criteria described above or any time deemed necessary by the physicians in charge
Intervention Type
Procedure
Intervention Name(s)
Rescue treatments
Intervention Description
Recruitment maneuvers, extracorporeal membrane oxygenation (ECMO), extracorporeal CO2 removal (ECCO2-R) after randomization will be allowed in both groups as rescue therapies and according to the decision of attending physicians: any of these procedures will be accurately recorded on the case report form.
Intervention Type
Procedure
Intervention Name(s)
Weaning from PEEP
Intervention Description
In order not to delay weaning from mechanical ventilation, when a patient is managed with assist/control or assist ventilation with PEEP higher than 8 cmH2O, a daily PEEP weaning trial will be performed whether PaO2/FIO2 ratio>150 mm Hg and FIO2<0.5: PEEP will be decreased to 8-5 cm H2O and arterial blood gas will be sampled after 20 -0 minutes. Previous ventilatory settings will be resumed if during the procedure transcutaneous oxyhemoglobin saturation decreases below 88%, PaO2/FIO2 falls below 150 mm Hg or if the patient experiences abnormal changes in respiratory rate or other clinical signs suggestive of respiratory distress. When PaO2/FIO2 is no lower than 200 mm Hg at PEEP≤8 cmH2O, the patient will be considered to have acceptable gas exchange on 8-5 cmH2O of PEEP and will be deemed capable to tolerate this setting
Intervention Type
Procedure
Intervention Name(s)
Weaning from mechanical ventilation
Intervention Description
A 30-120-minute spontaneous breathing trial will be initiated as the following criteria are met and whether the patient tolerates fully assist ventilation with PEEP≤8 cmH2O for at least 4 hours without experiencing hypoxemia (SpO2<88% or PaO2/FiO2<150mmHg): improvement or resolution of the underlying cause of acute respiratory failure normal sensorium correction of arterial hypoxemia (PaO2 ≥ 60 mmHg at a FiO2 ≤ 0.4 with PEEP ≤ 8 cmH2O); absence of fever (≥ 38 °C) or sepsis; blood hemoglobin concentration of 7 g/dL or more; hemodynamic stability For the purpose of the study, success of the spontaneous breathing trial will be defined as presence of the following criteria: respiratory rate < 35/min, arterial oxygen saturation ≥ 90%, heart rate < 120/min, systolic blood pressure > 90 and < 160 mmHg adequate cough. If the spontaneous breathing trial is successful, the patient will be extubated.
