Study Notes
Background and Purpose
- The study aimed to investigate the effects of Trendelenburg Chest Optimization (TCO) on cardiopulmonary outcomes in patients with Chronic Spinal Cord Injury (CSCI)
- Patients with CSCI often experience respiratory complications, which can lead to increased morbidity and mortality
Chest Optimization
- Chest optimization consisted of placing patients in a Trendelenburg position at 15 degrees for 30 minutes, with a washout period of 30 minutes between interventions
- The Trendelenburg position was used to improve lung recruitment and decrease atelectasis
- The intervention was combined with spontaneous breathing trials (SBTs) to evaluate cardiopulmonary outcomes
Patient Characteristics
- The study included 20 patients with CSCI, with an age range of 25-65 years
- The subjects were primarily veterans with tetraplegia, with varying levels of spinal cord injury
- Most patients had normal body mass index and did not have age-related disease-specific comorbidities
Measurements and Data Collection
- Cardiopulmonary variables, including tidal volume, minute ventilation, and cardiac output, were measured using a NICO monitor
- Measurements were taken before and after chest optimization and SBTs
- The researchers used a CircuVent device to bypass carbon dioxide (CO2)/flow during aerosolization of bronchodilators into the NICO circuit
Results
- TCO was associated with a 25% increase in cardiac output and a 30% decrease in minute ventilation
- The average SBT duration following TCO was 30 minutes
- The researchers found an unexpected increase in cardiac output during SBTs following TCO
Implications and Recommendations
- The study's findings support the use of TCO as a therapeutic intervention for patients with CSCI
- The Consortium for Spinal Cord Medicine recommends the use of chest optimization techniques, such as TCO, to improve pulmonary function in patients with low SCI
- The study's results highlight the importance of individualized care and the need for further research on neurorespiratory rehabilitation protocols for patients with CSCI
