Mechanical Ventilation in Multiple Fracture Ribs

Not Applicable

• Conditions: Mechanical Ventilation

• Registration Number: NCT03314701
• Lead Sponsor: Assiut University

Brief Summary

Chest trauma is the most common injury in the emergency trauma and rib fractures is the most common trauma in chest trauma. Severe rib fractures can cause paradoxical respiration and mediastinal swing, which has large effects on respiratory and circulatory system, result in acute respiratory distress syndrome. Mechanical ventilation can significantly improve the hypoxemia of the patients, correct paradoxical respiration, and treat the pulmonary atelectasis

Detailed Description

To compare between Biphasic Intermittent Positive Airway Pressure (BIPAP) ventilation and Airway Pressure Release Ventilation (APRV) mode in patients with multiple fracture ribs as regard:

* Resting Energy Expenditure

* Oxygenation

* Stability of Physiological Status as cardiovascular activity

* cardiac output

* arterial blood gas measurement including \[ blood PH, arterial oxygen tension, arterial carbon dioxide tension, bicarbonate level and base deficit\]

* lung and chest compliance

* Length of intensive care unit stay.

* The ICU mortality rate.

* The development of major complications as nosocomial infection (hospital acquired pneumonia and ventilator associated pneumonia), major atelectasis and pneumothorax.

Primary Outcome Measures

Name	Time	Method
Duration of mechanical ventilation	within one month	The total duration of ventilatory support in both groups from randomization to successful weaning (hours)

Secondary Outcome Measures

Name	Time	Method
Physiological dead space	within the first 48 hours	Physiological dead space will be measured in the two groups after 30 minutes by Volumetric capnography which is included in the metabolic module on General Electric ventilator
Resting Energy Expenditure	within the first 48 hours	Energy expenditure will be measured using indirect calorimetry via a metabolic module on General Electric ventilator \[CARESCAPE R860\]
