Synchronized Intermittent Mechanical Ventilation Versus Open Lung Ventilation With Spontaneous Respiration (SOLV)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The purpose of this study is to collect data on patients who are on breathing machines (ventilators) in the Trauma Surgical Intensive Care Unit (TSICU). This data may help us to determine if one form of assisted breathing is better than another. The two forms of assisted breathing being compared in this study are called BiVent and SIMV. (7) BiVent and SIMV are both delivered by a ventilator but differ in how they assist breathing. SIMV is an older form of mechanical breathing that blows air into the lungs to inflate the lungs. BiVent is a newer form of mechanical ventilation that permits the patient to pull air into the lungs as we normally do. Both BiVent and SIMV are currently being used on a regular basis in the TSICU. The investigators hope that this study will determine if one method of assisted breathing is better than another in preventing complications associated with mechanically assisted breathing.


Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Synchronized Intermittent Mechanical Ventilation vs Open Lung Ventilation With Spontaneous Respiration

Further study details as provided by University of New Mexico:

Primary Outcome Measures:
  • Reduction in ventilator days [ Time Frame: 4 years ]

Secondary Outcome Measures:
  • Progression to acute lung injury/acute respiratory distress syndrome (ALI/ARDS) [ Time Frame: 4 years ]

Estimated Enrollment: 198
Study Start Date: October 2007
Open Lung Ventilation
within 24 hours of arrival trauma patients with ISS >25 will be randomized to BiVent (APRV)
within 24 hours of arrival trauma patients with ISS >25 will be randomized to either SIMV or BiVent

Detailed Description:

SOLV Hypothesis:

A prospective, randomized trial directly comparing open lung ventilation (OLV) with spontaneous breathing (SB) utilizing BiVent on the Maquet Servo-I versus synchronized intermittent mechanical ventilation (SIMV) will be conducted in the trauma-surgical intensive care unit at the University Hospital (TSICU). Both OLV-SB and SIMV protocols have been designed according to lung protective strategies. The primary goal of the SOLV trial is to see determine if the early application of open lung ventilation will less ventilator days. In addition, several secondary endpoints will be evaluated. It is not anticipated that this study will be powered to show a mortality difference.
