Key Points. Question. Is there any extra benefit to applying more intensive alveolar recruitment strategies for high risk surgical patients already receiving perioperative small tidal volumes and protective lung ventilation Findings. An intensive recruitment strategy compared with a moderate recruitment strategy to treat patients with hypoxemia after cardiac surgery resulted in significantly lower severity of pulmonary complications during the hospital stay. The strategy caused a consistent shift to lower scores that favored use of an intensive recruitment strategy. Meaning. A more intensive alveolar recruitment strategy applied postoperatively may reduce the severity of pulmonary complications in patients with hypoxemia after cardiac surgery. Abstract. Importance. Perioperative lung protective ventilation has been recommended to reduce pulmonary complications after cardiac surgery. The protective role of a small tidal volume VT has been established, whereas the added protection afforded by alveolar recruiting strategies remains controversial. Objective. To determine whether an intensive alveolar recruitment strategy could reduce postoperative pulmonary complications, when added to a protective ventilation with small VT. Design, Setting, and Participants. Randomized clinical trial of patients with hypoxemia after cardiac surgery at a single ICU in Brazil December 2. Interventions. Intensive recruitment strategy n1. VT. Main Outcomes and Measures. Severity of postoperative pulmonary complications computed until hospital discharge, analyzed with a common odds ratio OR to detect ordinal shift in distribution of pulmonary complication severity score 0 to 5 scale, 0, no complications 5, death. Prespecified secondary outcomes were length of stay in the ICU and hospital, incidence of barotrauma, and hospital mortality. Results. All 3. 20 patients median age, 6. IQR, 5. 6 6. 9 years 1. The intensive recruitment strategy group had a mean 1. CI, 1. 7 to 2. 0 and a median 1. IQR, 1. 0 2. 0 pulmonary complications score vs 2. CI, 2. 0 2. 3 and 2. IQR, 1. 5 3. 0 for the moderate strategy group. Overall, the distribution of primary outcome scores shifted consistently in favor of the intensive strategy, with a common OR for lower scores of 1. CI, 1. 2. 2 to 2. P . 0. 03. The mean hospital stay for the moderate group was 1. CI, 3. 1 to 0. 3 P . The mean ICU stay for the moderate group was 4. CI, 1. 6 to 0. 2 P . Hospital mortality 2. CI, 7. 1 to 2. 2 and barotrauma incidence 0 in the intensive group vs 0. CI, 1. 8 to 0. 6 P . Conclusions and Relevance. Among patients with hypoxemia after cardiac surgery, the use of an intensive vs a moderate alveolar recruitment strategy resulted in less severe pulmonary complications while in the hospital. Trial Registration. Identifier NCT0. Introduction. Postoperative pulmonary complications are common after cardiac surgery, often increasing postoperative morbidity and mortality. The extracorporeal circulation. This harmful sequence may be accompanied by hypoxemia, pneumonia, ventilator induced lung injury, and acute respiratory distress syndrome ARDS. These complications may result in increased resources utilization, delayed mobilization, prolonged need of supplemental oxygen or mechanical ventilation,1. Recent studies have shown that intraoperative lung protective ventilation may reduce postoperative pulmonary complications. Different strategies for lung protection have been tested, either a simple reduction of tidal volume VT,2 or a low VT in combination with alveolar recruitment strategies moderate positive end expiratory pressure PEEP aided by recruiting maneuvers. In all these studies, however, the control group received nonprotective mechanical ventilation, with no PEEP and high VT 9 1. Lkg of predicted body weight PBW. Thus, the specific role extra benefit of alveolar recruitment strategies was not directly tested. From 2. 01. 1 to 2. VT ventilation during open abdominal surgery failed to show benefits. In fact, it caused more adverse effects. Only a small physiological study supports the benefit of more intensive alveolar recruitment strategies for patients also receiving low VT ventilation. That study, however, showed a decreased inflammation. This clinical trial evaluated the specific role of a more intensive alveolar recruitment strategy for reducing the severity of pulmonary complications in patients with hypoxemia already receiving protective ventilation with low VT after cardiac surgery. Methods. Study Design. This was a single center, randomized clinical trial performed at the Heart Institute Incor from the University of So Paulo in Brazil. Patients were enrolled between December 2. February 2. 01. 4 Figure 1. The study protocol was approved by the local ethics and research committee Supplement 1. Written informed consent was obtained from all participants. Participants. Patients were assessed for eligibility and gave consent on the eve of their surgery. Patients were included if they were undergoing elective cardiac surgery coronary artery bypass graft surgery, valve surgery, or both, with or without cardiopulmonary bypass and had hypoxemia when they were admitted to the intensive care unit ICU. Hypoxemia is defined as an arterial partial pressure of oxygen fraction of inspired oxygen Pao. Fio. 2 ratio of less than 2. Hg, collected during PEEP 5 cm H2. O. Patients were excluded if they were younger than 1. FEV1 FVC lt 7. Hg had left ventricular ejection fraction of less than 3. BMI of less than 2. BMI is calculated as weight in kilograms divided by height in meters squared needed emergency surgery or ventricular assist device needed more than 2 gkgmin of norepinephrine had refractory hypotension or arrhythmia at entry had pneumothorax or air leak syndrome at entry or were enrolled in another study. Study Protocol. Full details of the surgical and anesthetic techniques are given in Supplement 2. All postoperative patients were admitted to the ICU received volume controlled ventilation and had a VT of 6 m. Lkg of predicted body weight PBW, Fio. PEEP of 5 cm H2. O. After confirming entry or exclusion criteria, patients were randomly assigned to 1 of 2 strategies lung protective ventilation plus intensive alveolar recruitment strategy or lung protective ventilation plus moderate alveolar recruitment strategy. Randomization was performed only after patient enrollment, with a computer generated list 1 1 allocation ratio, generated online by a web based program that ensured allocation concealment Figure 1. All patients were then sedated with standard intravenous boluses of fentanyl or midazolam and shortly paralyzed with cisatracurium during lung mechanics measurements. Subsequently, a low flow pressure volume curve was performed PV Tool, Galileo Gold ventilator Hamilton Medical. In both groups, the maneuver started from a baseline PEEP of 5 cm H2. O, with airway pressures progressively increased up to 3. H2. O ramp speed of 2 cm H2. O per second, followed by gradual decrease back to 5 cm H2. O equivalent ramp speed. After 4 hours of mechanical ventilation according to each randomized strategy, a second pressure volume curve was performed.
