About this study
Official title: Evaluation of Efficacy of Recruitment Maneuver Using Lung Ultrasound in Trauma Patients
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UltrasoundDiagnostic test
Evaluate participant's lung condition using ultrasound. Using lung ultrasound scoring, more than 1 point needs recruitment maneuver
| Study group | Role | What they receive |
|---|---|---|
| sono group | Experimental | Evaluate the participant's lung condition using ultrasound and do recruitment maneuver if it is necessary Receives: Diagnostic Test: Ultrasound |
| control group | No intervention | If participants need recruitment maneuver (decreasing saturation, peak airway pressure > 35 mmHg) by clinical judgement, do recruitment maneuver not using lung ultrasound |
What is being measured
The primary outcome is the main question the study is designed to answer.
arterial 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
Measured: 2 hours
Secondary outcomes (1)
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
Measured: 2 hours
