Q

why do we avoid milking or stripping the tube?

A

can generate extreme negative pressures in the chest tube and does little to maintain chest-tube patency

Q

what do you do if a chest tube becomes disconnected and contaminated?

A

submerge the tube 1”-2” (2-4 cm) below the surface of a 250mL bottle of sterile water or saline solution until a new CDU is set up

Q

by placing tube in sterile water or saline solution after it has been contaminated, what are we doing?

A

establishes a water seal, allows air to escape, and prevents air re-entry

Q

indications for chest tube removal

Study These Flashcards
A
  • improved respiratory status
  • symmetrical rise and fall of the chest
  • bilateral breath sounds
  • decreased chest-tube drainage
  • absence of bubbling in the water-seal chamber during expiration
  • improved chest X-ray findings
23
Q

removal of chest tube steps

Study These Flashcards
A
  • explain procedure to pt, make sure they know how to do vasalva maneuver
  • admin of analgesics
  • dc suction
  • position pt in semi fowlers
  • remove dressing and sutures; clamp tubing
  • pull out tube when pt does Vasalva; apply occlusive dressing secured with tape
  • obtain CXR
24
Q

what is nursing care after chest tube removal?

Study These Flashcards
A

ongoing resp assessment, VS, monitor for drainage, comfort level

25
prolonged leaks
last more than 5 days after thoracic surgery
26
if you detect leak at insertion site what should you do?
apply petroleum gauze and sterile dressing over site
27
what happens with a significant internal air leak?
you can palpate subcutaneous emphysema
28
what leads to tension pneumothorax?
large persistent leak with no evacuation outlet
29
when should you dc suction before removal?
some literature suggests dc-ing suction 24hrs prior to taking out a chest tube to prevent possible air leak
30
when should you obtain CXR after removal?
within 2hrs of removal
31
what do you do in an unplanned removal?
stay calm, cover insertion site with hand, call for help, cover site with dressing, notify MRP, obtain CXR
32
if you didn't see the chest tube come out, what do you do?
- If patient appears to be in respiratory distress, ask him or her to exhale forcefully as you lift your hand off the insertion site; before the patient’s next inhalation, quickly cover the site again. - Have the patient repeat this a few times
33
if you’re walking with your patient and the chest tube becomes dislodged where it connects to the drainage tubing, what do you do?
- immediately close off the tubing to air with your gloved hand by crimping it or using a clamp, if readily available, or place the end of the tube in a bottle of sterile water, creating a water seal - prepare a new sterile chest-drainage collection device, or retrieve a new sterile connector while you safely return the patient to bed - observe the patient for s&s of respiratory decline, then reconnect the chest tube to the new drain and unclamp it
34
how does re-expansion pulmonary edema occur?
results from rapid removal of large amounts of air or fluid
35
what is a chest tube?
large catheter inserted through the thorax to remove fluid (effusions), blood (hemothorax), and/or air (pneumothorax)
36
what placement of chest tubes drain air?
Apical (2nd or 3rd intercostal space) and anterior chest tube placement
37
what placement of chest tubes drain fluid/blood?
Chest tubes placed low (usually in 5th or 6th intercostal space) and posterior or lateral
38
when is fluid drainage expected?
after open chest surgery and some chest trauma
39
when is a mediastinal chest tube used?
after open heart surgery
40
two chamber system vs three chamber system
- Two-chamber system permits liquid to flow into the collection chamber, and air flows into the water-seal chamber - Three-chamber system promotes the drainage of fluid and air with controlled suction
41
what is similar about both two and three chamber systems?
1st chamber provides a compartment for fluid and the 2nd for either a water seal or a one-way valve
42
T or F: Infections can occur with chest tubes.
Yes, but rarely
43
management of chest tube drainage system
- Avoid dependent loops of the drainage tube; or when these loops cannot be avoided (such as when pt is sitting), lift and clear the tube every 15-30 mins - Keep chest drainage tubing and the collection system below the level of the pt's chest. Keep the tubing above the collection system to allow drainage by gravity. - Tailor the length of the drainage tube to the pt. The tubing must be long enough to allow a pt to move but not so long that dependent loops hang down the side of the bed.
44
what can happen if tubing is coiled, looped or clotted?
drainage is impeded and can result in a tension pneumothorax
45
what is not considered normal in water seal chamber?
○ Constant bubbling in the water seal or a sudden, unexpected stoppage of water-seal activity is considered abnormal and requires immediate attention ○ Constant left-to-right bubbling (when facing the indicator) or violent rocking is considered abnormal and indicates an air leak
46
what would a sudden decrease in drainage indicate?
possible clot or obstruction in the chest tube
47
what indicates fresh bleeding from the thorax?
sudden increase of more than 250mL of drainage over 1hr
48
what are the different colours of drainage?
- Drainage from recent open-chest surgery initially is bright red and gradually becomes serous as post-op course continues - Blood tinged fluid = malignancy, pulmonary infarction, or severe inflmtn - Frank blood = hemothorax - Pus = empyema
49
absence of bubbling in three chamber water system indicates what?
no suction is occuring; raise suction setting to restore gentle bubbling
50
what happens when appropriate amount of water is added to three chamber water system?
a 2cm water seal is established
51
bubbling in water seal chamber indicates...
an air leak
52
dry suction system
○ Provides higher suction pressure levels if needed, easy setup, no water in suction-control chamber, and absence of continuous bubbling
53
what is the point of the water seal chamber?
it acts as a one way valve so air cannot enter the pleural space
54
when setting up a waterless system, what do we add and why?
15mL of NS or sterile water into diagnostic indicator injection port; Allows observation of rise and fall of water in diagnostic air leak window
