In trauma patients, the incidence of pulmonary contusion is frequent. Recruit maneuver using lung ultrasound could be improve oxygenation in trauma populatioin, howevere, there is no previous study. The aim of this study is evaluation of the efficacy of lung recruitment using ultrasound in perioperative period in trauma patients.
In trauma patients, the incidence of pulmonary contusion is 17-75%. Pulmonary contusioin leads to atelectasis, lung consolidatioin. Finally it could results acute respiratory distress syndrome. Lung ultrasound is non-invasive and available in anytime even during surgery. Previous studies showed recruitment maneuver using ultrasound improved postoperative oxygenation in pediatric cardiac surgery. In adults, recruitment maneuver not using ultrasound improved oxygenation after cardiopulmonary bypass. There is no study in adult trauma population. The aim of this study is evaluation of the efficacy of lung recruitment using ultrasound in perioperative period in trauma patients.

RECRUITINGarterial oxygen partial pressure / fractional inspired oxygen ratio at end of surgery
= P /F ratio; Smaller value respresents poor outcome Using arterial blood gas analysis the difference between baseline (immediate after intubation) and end of surgery : If P/F ratio difference is improved compared to baseline, it means recruitment maneuver is effective
Time frame: 2 hours
Lung ultrasound score
Using lung ultrasound, evaluate lung condition in both group at end of surgery Scoring using "lung ultrasound scoring" Scoring range: 0, normal; 1, small loss of aeration; 2, moderate loss of aeration; 4, severe loss of aeration
Time frame: 2 hours
