Tracheal Lavages Sore Throat
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. tracheal lavages: tracheal lavages obtained during endotracheal intubation.
Tracheal Lavages No Sore Throat
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. tracheal lavages: tracheal lavages obtained during endotracheal intubation.
Healthy Control
A one time blood sample of approx 30cc will be collected by venipuncture.
