Role of Neutrophil Activation
Patients will undergo placement of an endotracheal tube (ETT) as standard of care. Tracheal lavage will be conducted using 5 mL of sterile saline solution by a push/suction technique. Specimen samples obtained by wall suction will be collected at 2 time points following intubation.
Blood samples will be obtained at 2 time points, simultaneous with the collection of the tracheal specimens.

|Official Title:||Sore Throat Secondary to Endotracheal Intubation: the Role of Neutrophil Activation|
- identifying neutrophil surface changes [ Time Frame: 90 minutes after surgery ]Physiologic and demographic measurements such as temperature, oxygenation, and blood pressure, gender, body mass index and coexisting diseases
|Study Start Date:||March 2013|
|Estimated Study Completion Date:||April 2018|
|Estimated Primary Completion Date:||December 2017 (Final data collection date for primary outcome measure)|
After the placement of the endotracheal tube (Hi-Lo™ Evac Mallinckrodt), tracheal lavages will be performed.
A simultaneous blood sample of approx 5cc, will be collected by venipuncture or by sampling from intravenous or arterial line if available. The same procedure for collection of tracheal sample and blood will be repeated at the end of the surgical procedure and immediately prior to removal of the ETT. A total of approx 10cc blood will be collected for research purposes.
Procedure: tracheal lavages
tracheal lavages obtained during endotracheal intubation.
