Effect of Positive Expiratory Pressure on the Management of Chest Trauma

Study Overview
=================
Brief Summary
-----------------
Chest trauma (CT) are a common problem in our environment caused mainly by traffic accidents and causal and domestic accidents among the elderly population. CTs, in some situations, can lead to sequelae such as fibrothorax secondary to hemothorax and / or empyema and residual chronic pain. Clinical regulations and guidelines recommend a guideline for chest physiotherapy (CP) for all patients with rib fractures, but there is little scientific evidence. It would be interesting to establish CP treatment protocols and describe the most appropriate techniques according to the type and stages of thoracic trauma consolidation. Objective: To evaluate the effect of Positive Expiratory Pressure (PEP) breathing added to conventional CP in terms of aid secretion clearance, pain control, pleuropulmonary radiological abnormalities, restoration of lung function, and admission days in the immediate phase of the CT.

Detailed Description
-----------------
After acceptance to participate in the study, patients will be computerized randomized into 2 groups: PEP group: positive expiratory pressure breathing. CONTROL group: conventional CP treatment without positive pressure brething. The period between day 0 and 20 days post-trauma is considered an immediate phase of CT. Once admitted, an initial evaluation by the doctor will be performed, and pleuro-pulmonary complications, the presence of respiratory failure, and pain control will be evaluated. The chest physiotherapist will perform a clinical and secretion assessment using the Seva test and a dynamic costal examination. The medical treatment of pain control will begin, and the treatment of CP will begin, where it will be randomized in 2 groups: 1- PEP group: positive expiratory pressure breathing with the help of a PEP bottle device. 2-CONTROL group: conventional CP treatment without positive pressure breathing will be daily FR sessions, on weekdays. Upon admission, hospital discharge and post-discharge, radiological checks (simple radiography) will be performed and forced vital capacity will be measured with forced spirometry.
