The aim of this prospective study was to evaluate the efficacy of performing a recruitment maneuver (RM) before tracheostomy, in order to improve oxygenation. METHODS: We enrolled 29 eligible trauma patients with acute lung injury criteria requiring tracheostomy in a university ICU. Subjects were ventilated on volume controlled mechanical ventilation (tidal volume of 6 mL/kg) and FIO2 set at 1.0. Subjects were randomized into 2 groups: RM group (subjects who underwent RM 10 min before PDT, 15 subjects) and no-RM group (subjects without application of RM before PDT, 14 subjects). RM was performed by imposition of continuous positive airway pressure of 40 cm H2O for 40 seconds. We collected gas exchange, respiratory, and hemodynamic data 5 times: 1 hour before RM, 5 min after RM, 5 min after PDT, 30 min after PDT, and 6 hours after PDT. RESULTS: Subjects who underwent RM had a significant increase in PaO2; 5 min after the maneuver, PaO2 increased from 222.6 ± 33.4 mm Hg to 341.3 ± 33.1 mm Hg (P < .01) and was always significantly maintained throughout the following times of the study, compared to the no-RM group: in the RM and no-RM groups, respectively, 260.7 ± 35.4 mm Hg vs 108.5 ± 36.9 mm Hg 5 min after PDT; 285.6 ± 29.1 mm Hg vs 188.4 ± 21.4 mm Hg 30 min after PDT; and 226.3 ± 24.8 mm Hg vs 147.6 ± 42.8 mm Hg 6 h after PDT (P < .01). CONCLUSIONS: Our study suggests that application of RM before PDT could be useful to avoid hypoxemia following such procedure, by reducing fall in PaO2 and preventing the decrease in oxygenation values below baseline at 6 hours.
