Chest Tubes Flashcards
What might require a CT into pleural space?
Pneumothorax (spontaneous, tensioned, closed, open)
Pleural effusion
Hemothorax
Empyema (pyothorax)
What is a spontaneous pneumo?
Who is most at risk?
Pneumothorax in the absence of underlying disease or trauma; this is termed spontaneous pneumothorax.
Tall, thin male smokers
Describe an open pneumothorax
Traumatic Pneumothorax (open) Penetrating chest trauma causes hole in chest wall. Communication between the pleural space and the environment Atmospheric air is sucked into the pleural space through the chest wall wound. Lung collapses. Mediastinal movement with each respiration
Describe iatrogenic causes of pneumothorax
Thoracentesis
Chest surgery
Insertion of central line
Incorrect placement NG tube
S and S of tensioned pneumo?
What are the complications ?
Tachypnea Dyspnea Anxiety Tachycardia Pleuritic chest pain Cyanosis Use of accessory muscles Decreased or Absent breath sounds Decreased movement of affected side Subcutaneous Emphysema
impaired oxygenation and/or ventilation. hemodynamic instability (pressure on heart prevents contraction)
What is mediastinal shift and what can it cause?
shifting or moving of the tissues and organs that comprise the mediastinum (heart, great vessels, trachea, and esophagus) to one side of the chest. impairs ventilation, venous return and can compress/twist blood vessels
Two CT placements for pleural drainage?
Chest tubes placed high (second-third intercostal space) are to remove air (air rises).
Chest tubes placed low (fifth- sixth intercostal space) are to remove blood and fluid.
Describe different chambered systems?
one- For pneuma only (drain and water seal
Two- Drain then water seal
Three- Drain water seal, suction
What is a waterless system?
Why use it?
Heimlich valve (one way)
Little to no drainage, no suction
Who can remove sutured CT’s
Two RN’s in Island Health
When can you see tidying in water seal pressure gauge.
Tidaling is normal and represents can in negative pressure of pleural space inspiration to expiration. More visible when suction is off.
What 3 things should you document about fluid coming into CT drainage system?
Volume
Rate
Nature of drainage
Why might tidaling stop
The lungs have re-expanded
The drainage tubing is kinked
There is an obstruction
In wet suction is bubbling normal?
Yes… the water is used as a suction control. Dry uses the dial with billows indicator instead
When are air leaks likely and unlikely?
How do you solve them?
Normal to have a small air leak first 24 hours
Air leak will often clear after a couple of coughs
Often air leaks are managed with increase in suction
Very rare to have increased air leak after 24 hours - In this case it is usually from the system so clamp briefly from patient down to locate the leak
