Abstract
Introduction
Accumulation of secretions in an endotracheal tube can increase the resistance to flow resulting in an increased patient work of breathing when the patient is interacting with the ventilator. Retained secretions can also serve as an infection risk. Standard suction catheters are limited in their ability to keep the lumen of the endotracheal tube clear. A novel closed-suction catheter has been introduced that incorporates a balloon at its distal end that, when inflated, physically scrapes secretions out of the endotracheal tube (CleanSweep catheter (CSC), Teleflex, Morrisville NC). We hypothesized that the CSC would be more efficient at removing secretions from inside the endotracheal tube than a standard suction catheter (SSC).Methods
We performed a bench study examining resistive pressures across different sizes of endotracheal tubes when cleaned by the CSC as compared with an SSC. This study was followed by a prospective crossover study again comparing the CSC with an SSC in intubated intensive care unit patients receiving mechanical ventilation and requiring frequent suctioning.Results
For the bench study the CSC was significantly better in reducing airway resistive pressures (P < 0.001). In the prospective crossover study the CSC over 2 h also removed significantly more secretions than the SSC (P < 0.05).Conclusion
Both our bench and crossover clinical study demonstrated improved clearance of secretions with the CSC vs an SSC. Further research is needed to ascertain the clinical outcome benefits of enhanced secretion removal.Type

- Mechanical Ventilation and respiratory failure. Current projects involve studying patient-ventilator interactions during modes of support that require patient activity. The focus is on ventilatory muscle function during these assisted modes. Other projects include evaluating respiratory system mechanics in acute respiratory failure and the role of ECMO in the adult. Duke is also one of several institutions in the NIH ARDS Network, a consortium designed to perform multi-center trials.
2) Diffusing capacity of the lung for carbon monoxide. Current projects involve using a rapidly responding gas analyzer to measure lung diffusing capacity in discrete regions of the lung. These analyses are being extended into mechanically ventilated patients.
3) COPD. Current projects involve studying the physiology of cardio-respiratory conditioning in patients with obstructive lung disease and the role of pulmonary rehabilitation in improving COPD outcomes. Duke is also a member of two NIH sponsored multicenter programs: the COPDgene project correlating genetic profiles with physiologic/clinical phenotypes; and the NIH LOTT project evaluating the role of oxygen therapy in exercise and sleep hypoxemia.
4) Aerosol delivery systems. The current project is the development of a prototype aerosol generating catheter that can be directly inserted into the airways. Studies are being conducted in both ex vivo animal lungs and in mechanically ventilated patients.
