Head Movement Effect on Different Tracheal Tubes
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Effect of Head Movement on the Position of Different Tracheal Tubes Determined Radiologically|
|Study Start Date:||April 2007|
|Estimated Study Completion Date:||January 2009|
|Estimated Primary Completion Date:||December 2008 (Final data collection date for primary outcome measure)|
An endotracheal tube, which is used to secure the airway and allow ventilation of the lungs during general anesthesia, is inserted into the trachea either through the nose or mouth. In children, different formulae exist to determine the approximate size of the tube according to age, and how far it should be advanced into the airway. Once a tracheal tube is inserted, its position is routinely checked to make sure both lungs are ventilated. To prevent displacement, the tube is taped to the lip, chin or at the nose. However, head movement could cause alteration of the tube position, and risk selective endobronchial intubation or inadvertent extubation. Knowledge of how the different tracheal tubes move with head position can help determine the best tube selection to reduce the risk of accidental tube advancement or removal, in cases where certain head positions are required for surgical access.
The aim of this study is to assess the accuracy of the formulae commonly used in our institution for depth of breathing tube placement, and to measure the degree of tube displacement on head movement with different types of tube. Testing the formulae will enable us to be more aware of how frequently inaccurate tube placement may occur. Knowledge of how the different breathing tubes move with head position can help determine the best tube selection to reduce the risk of the tube going in too far or coming out accidentally, for cases were certain head positions are required for surgery.
