Coaxial Independent Clinical Study Overview
Redax is excited to announce results of an independent clinical Thoracic Surgery study. The study was performed at the Thoracic Surgery Department at the University of Eastern Piedmont in Novara, Italy. After comparing patients receiving a 24 Fr Redax Coaxial drain to patients receiving a 24 Fr standard chest tube, the authors conclude the Redax Coaxial drain is safe and efficient in air-leak and fluid evacuation. In addition, the study indicates that the Redax Coaxial is superior to standard chest tubes in fluid evacuation and patient comfort. Below are some of the highlights:
Enhanced Drain Efficiency Through Innovative Design
The data indicates the Redax Coaxial’s composition and high-flow transition has better overall drainage, flow and patency compared to a standard chest tube.
•   The Coaxial drained 73% of the total amount of fluid in the first critical hours post operatively as compared to 48% in the conventional tube patients.
•   No Coaxial drains were occluded at removal compared to occlusion found in 5.8% of the conventional tube patients.
Greater Patient Satisfaction
Using the VAS score to record patient pain, the Redax Coaxial patients had less pain than patients with the standard chest tube. Patient comfort is enhanced in patients with the Coaxial due to its silicone construction which offers more elasticity and its fluted profile which reduces tissue invagination.
•   Mean post-operative day 1 (POD1), the VAS score at rest (VATS) was 2.3+1.4 for Coaxial patients as opposed to 3.5+2.2 for standard chest tube patients.
Improved Patient Outcomes
The data indicates that the enhanced drainage performance of the Coaxial removes more fluid in the early, post-operative, critical hours than the standard chest tube thereby reducing the amount of retained fluid found in the pleural cavity after drain removal. Compared to the standard chest tube, the Redax Coaxial decreases post-operative complications like sputum retention, atelectasis, pneumothorax and hemothorax.
•   At POD1, chest X-rays show a pleural fluid retention rate at 9.6% for the Coaxial, opposed to 26.2% for the standard chest tube.
•   At POD1, chest X-rays show the Coaxial pneumothorax rate at 27% and the standard chest tube at 33%.
•   After tube removal, chest X-rays show the residual pleural cavity rate for the Coaxial drain is 15% while the standard chest tube is 25%.
•   After tube removal, chest X-rays show the pleural fluid retention rate at 5.7% for the Coaxial, compared to 20.2% for the standard chest tube.
