Q

Chest tube- lung normal pressure

A
  • Normal breathing mechanisms operate on the principle of negative pressure
  • Pressure in chest cavity is normally lower than the atmosphere causing air to move into the lungs during inspiration
  • Whenever the chest is opened, there is loss of negative pressure
  • Collapsed lung result from opening of chest or collection of air, fluid, or other substances (serous fluid, pus, blood, etc.)

Q

What’s a chest tube

A
  • Surgical incision of the chest wall almost always causes some degree of pneumothorax.
  • CT Improves gas exchange and breathing
  • Used to re-expand the involved lung to remove exchange

Q

Different chest tube insertion

A
  • Insertion into pleural space restores negative intrathoracic pressure needed for lung re-expansion after surgery or trauma
  • Insertion into the mediastinal space (extra pleural space) anteriorly or posteriorly drains blood after surgery

Q

Types of chest tube

A

●Small-bore and large bore (7-12Fr), have a one-way valve apparatus to prevent air from moving back into the chests.

●Large-bore (range up to 40Fr) are usually connected chest drainage system to collect fluid and air.

●CT positioned after insertion, sutured to the skin, connected to a drainage apparatus to drain fluid and air from pleural or mediastinal space.

Q

Types of radical neck dissection

A

Q

Non surgical therapy for cancer

A

Radiation:

  • can be used to treat small cancers or when lesions cannot be removed
  • make tissue become fibrotic and hard to remove surgery is usually done first
  • ulceration of oral mucosa, pain, dry mouth, loss of taste, dysphasia, fatigue necrosis and edema

Chemo:

  • used in combination with radiation
  • shrink lesion before surgery

Palliative:

  • When prognosis is poor, cancer is inoperable, patient declined surgery
  • placement of GI tube of unable to swallow, suctioning, pain meds
23
Q

Larynx radiation

A

Goal:
-eradicate the cancer and preserve function of the larynx
-Can be use preoperative to reduce size of the tumor
Retains a near-normal voice (a benefit)

Complications:

  • Chondritis (inflammation of the cartilage)
  • stenosis (may require largyngectomy
24
Q

25
Q

Larynx cancer Surgery’s

A

•Vocal cord stripping (less invasive).
- Removal of the edge of the vocal cord mucosa

•Cordectomy: (less invasive).
- An excision of the vocal cord.

•Laser (Laser microsurgery).
- Method of choice. Shorter recovery, fewer side effects.

•Partial laryngectomy:

  • portion of larynx removed with one vocal cord and the tumor.
  • Airways remain intact. No expected swallowing problems.
  • May change voice quality or hoarseness may result.
  • High cure rate.
26
Q

Total Laryngectomy Effects:

A
  • Permanent voice loss
  • Permanent tracheostomy.
  • Alternatives to normal speech is required. ( Includes Blom-Singer valve to speak without aspirating).
  • Patient has no voice but has normal swallowing.
  • Must breathe through a stoma
27
Q

Larynxectomy planning for Speech

A

•Speech therapists or pathologists evaluates pre-op
•Plan post op communication strategies and speech therapy
•A system of communication is established

Q

Thyroid

Clinical Manifestations

32
Q

Thyroid diagnostic

A
  • Palpation of enlarged thyroid or mass
  • Ultrasound, CT scan, MRI, PET

- If nodule does not take up radioactive iodine it’s “cold” and higher risk of cancer

• Test:

  • Serum Calcitonin
  • Serum thyro-globulin
33
Q

Thyroid Cancer treatment

A

  • Chemotherapy
34
