- Conditions
- Acute Respiratory Distress SyndromeAcute Lung Injury
- Interventions
- Behavioral: Recruitment maneuverOther: without recruit maneuver
- Registration Number
- NCT01552070
- Lead Sponsor
- Chang Gung Memorial Hospital
- Brief Summary
The purpose of this study is to investigate the change of extravascular lung water (EVLW), cytokine and oxygenation parameters in patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) after alveolar recruitment maneuver.
- Detailed Description
This investigation is a prospective randomized control study. Informed consents will be obtained from all patients or their surrogates prior to the procedure of alveolar recruitment maneuver and PiCCO monitoring system.
Patients and methods:
From September 2010 to September 2012, consecutive patients with ALI/ARDS undergo alveolar recruitment maneuver will be enrolled at Chang Gung Memorial Hospital, a university-affiliated hospital in Taiwan. EVLW will be measured by PiCCO monitoring system, alveolar recruitment maneuver will be setting by protocol under supervision of chest physicians and respiratory therapists. Serum cytokine such as endothelin-1, TNF-, IL-6, Tie-1, Tie-2, angiopoietin-1, angiopoietin-2,VEGF and thrombomodulin will be measured.

Group Intervention Description With recruitment maneuver group Recruitment maneuver Recruitment maneuver will be performed immediately (within 2 minutes) after intubation, consisting of a continuous positive airway pressure of 40 cmH2O over 30 seconds. Blood gases were sampled and blood samples taken for culture before, within 2 minutes, 5 minutes, and 30 minutes after intubation. Haemodynamic and respiratory parameters were continuously recorded throughout the study. Without recuritment maneuver without recruit maneuver After oral intubation, each patient will be mechanically ventilated, with a tidal volume of 6mL/kg, a respiratory rate of 20 to 25 breaths/minute, a positive end-expiratory pressure (PEEP) of 5 cmH2O, and an FiO2 of 100%. PEEP titration according to FiO2 and ARDSnet.
- Primary Outcome Measures
Name Time Method Extravascular lung water change with/without recruitment maneuver. 7 days The Extrvascular lung water (EVLW) measurement will be based on transpulmonary thermodilution method. This method was recently introduced as part of the PiCCO plus system (Pulsion Medical System, Munich, Germany). EVLW were recorded and compared between patients with and without recruitment manevuer.
- Secondary Outcome Measures
Name Time Method ICU survival 28days From September 2010 to September 2012, consecutive patients with ALI/ARDS undergo recruitment maneuver or not randomly will be enrolled. Serum cytokine such as endothelin-1, TNF-, IL-6, Tie-1, Tie-2, angiopoietin-1, angiopoietin-2,VEGF and thrombomodulin will be measured. Further ventilator use duration, weaning rate, ICU stay, safety and ICU survival were recorded and compared between patients with and without recruitment manevuer.
