Trial 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.

About this study

Official title: Biphasic Intermittent Positive Airway Pressure (BIPAP) Versus Airway Pressure Release Ventilation (APRV) in Patients With Multiple Fracture Ribs

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

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Biphasic Intermittent Positive Airway Pressure (BIPAP)Device

    Following endotracheal intubation BIPAP mode will be started with:

    • Inspiratory positive airway pressure [IPAP] at 20 cmH2O
    • Expiratory positive airway pressure [EPAP] at 5 cmH2O
    • PRESSURE SUPPORT is difference between these two pressures [IPAP]- [EPAP]
    • Mandatory pressure will be delivered at rate of 10-12/min. To produce an end tidal carbon dioxide partial pressure in the range of 35-40 mmHg hypercapnia will not be allowed
  • Airway Pressure Release Ventilation (APRV)Device

    • high airway pressure (Phigh) will be set at 20 cmH2O
    • low airway pressure ( Plow) will be set at 5 cmH2O
    • the release phase setting will be adjusted to terminate the peak expiratory flow rate to ≥ 50%; release frequency of 10-12 cycles/min
    • T high at 4.5-6 seconds
    • T low at 0.5 to 0.8 second

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Duration of mechanical ventilation

    The total duration of ventilatory support in both groups from randomization to successful weaning (hours)

    Measured: within one month

Secondary outcomes (2)
  1. Resting Energy Expenditure

    Energy expenditure will be measured using indirect calorimetry via a metabolic module on General Electric ventilator [CARESCAPE R860]

    Measured: within the first 48 hours

  2. Physiological dead space

    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

    Measured: within the first 48 hours

Questions about this trial

What is this clinical trial studying?

A study testing Biphasic Intermittent Positive Airway Pressure (BIPAP) and Airway Pressure Release Ventilation (APRV) in people with Mechanical Ventilation, run by Assiut University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Duration of mechanical ventilation (time frame: within one month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2018.
