Recruitment Maneuver Using Lung Ultrasound in Trauma Patients

Not Applicable

Recruiting

• Conditions: Trauma; Recruitment
• Interventions: Diagnostic Test: Ultrasound

• Registration Number: NCT04008758
• Lead Sponsor: Ajou University School of Medicine

Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
sono group	Ultrasound	Evaluate the participant's lung condition using ultrasound and do recruitment maneuver if it is necessary

Primary Outcome Measures

Name	Time	Method
arterial oxygen partial pressure / fractional inspired oxygen ratio at end of surgery	2 hours	= 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

Secondary Outcome Measures

Name	Time	Method
Lung ultrasound score	2 hours	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
