Chapter 32: Endobronchial Tubes + Bronchial Blockers Flashcards
Three principle surgical uses for use of endobronchial tube + blockers?
Thoracic surgery
Non-thoracic surgery
Bronchopulmonary lavage
What is bronchopulmonary lavage?
The irrigation or washing out of the bronchi and bronchioles to remove pulmonary secretions
Which pulmonary surgeries might require an endobronchial tube?
Segmental resection, lobectomy, pneumonectomy
Which bronchial surgeries might require an endobronchial tube/
Resection, repair
Thoracic surgeries that may require an endobronchial tube include:
Lungs
Bronchi
Pulmonary vessels
Chest wall
Non-thoracic surgeries that may require an endobronchial tube include:
Spine
Vascular
GI
In which vascular surgery might you use an endobronchial tube?
Aorta
Which GI surgeries may require an endobronchial tube?
Esophagus
GE junction
Reasons you may use an endobronchial tube during surgery?
Infection, hemorrhage (disease or trauma) call for the isolation of the right + left lungs
Parynchema: provide unilateral support (oxygenation + ventilation to one lung)
Example of disease in lungs that would require endobronchial tube:
Bronchopleural fistula
Which lung is easier to mainstem?
Right side
What is the angled takeoff of the right main bronchus?
20*
What is the angled takeoff of the left main bronchus?
40*
Length of right main bronchus before RUL takeoff?
2.5 cm
Length of left main bronchus before LUL takeoff?
5 cm
Which lung has two lobes?
Left
Which lung has three lobes?
Right
Line that separates RUL + RML?
Horizontal fissure
Line that separates RML + RLL?
Oblique fissure
Line that separates LUL + LLL?
Oblique fissure
Which lung has a horizontal fissure?
Right lung
Anatomical position of the LLL in relation to the LUL?
LLL is posterior to LUL
In which CXR view can you best visualize the RML?
Posterior + lateral
Name three devices that we use in one-lung ventilation:
Endobronchial tube
Integrated ETT-bronchial blocker
ETT + bronchial blocker
A univent ETT is an example of:
an integrated ETT-bronchial blocker
Example of integrated ETT-bronchial blocker?
Univent ETT
Two examples of bronchial blockers that are to be used in conjunction with (but are not integrated parts of) an ETT?
Arndt device
Rusch endobronchial blocker
Arndt device + Rusch endobronchial blocker are two examples of:
ETT + bronchial blocker
What aspect of the double lumen tube separates the lungs from the environment?
Tracheal cuff
Purpose of tracheal cuff?
Separates the lungs from the environment
Purpose of endobronchial cuff?
Separates the two lungs from each other
What aspect of the double lumen tube separates the two lungs from each other?
Endobronchial cuff
Distinguishing feature of Right-sided double lumen ETT?
It has a ventilation slot for the RUL (make sure it is placed at the level of the RUL).
In a double lumen tube, what is the purpose of one lumen ending in the trachea + the other in a single lung?
We can control whether or not we ventilate both lungs at once (trachea) or one lung at a time (lung).
Method of visualization when placing EBT?
FFOB
Double lumen tubes are sized based on:
height
How do you confirm that you have successful placed a double lumen tube without the use of FFOB?
Clamp one lung off; when you ventilate, you should hear breathing sounds on one side but not the other
Which endobronchial tube has a clear lumen and a blue lumen? Which is the blue lumen?
Broncho-Cath
Blue = bronchial
What color is the proximal balloon on a Broncho-Cath?
Clear
What color is the distal balloon on a Broncho-Cath?
Blue
What is a univent?
A conventional ETT with integrated bronchial blocker
The OD of a normal ETT is reflected in what aspect of a Univent?
OD
On a Univent, which balloon is blue?
The pilot balloon of the tracheal cuff.
Which endobronchial tube has a distal end with an ETT cuff and two lumens?
Univent (integrated ETT + bronchial blocker)
The ETT proximal end of a Univent has:
15 mm circuit connector
ETT cuff inflation system
Blocker port
The bronchial blocker proximal end of a Univent has:
Blocker inflation system
Blocker port
Blocker locking mechanism
Which endobronchial tube requires the use of a fiberoptic scope as an introducer?
Arndt endobronchial blocker
How does the Ardnt endobronchial blocker relate to an ETT?
It has a special connector that is compatible with the ETT: use that connector as a port of sorts to thread the Arndt device along with the fiberoptic scope.
Which endobronchial blocker has two proximal balloons, a radiopaque shaft, and bifurcated distal extensions/
Rusch endobronchial blocker
The distal end of which endobronchial blocker is Y-shaped?
Rusch
Which endobronchial blocker has a camera and light source, thereby eliminating the need for FFOB assistance?
ETView Medical VivaSight
Air volume required to inflate bronchial cuff?
6-7 cc
When you switch from one-lung ventilation to two-lung ventilation, what are some changes you should make to your ventilation settings?
Change your rate and tidal volumes (therefore minute ventilation) to prevent volutrauma.
If a patient starts to desaturate during one-lung ventilation, what are some things you can do?
100% O2
Apply CPAP to non-ventilated lung.
