Q

Ephedrine and Heart transplant patient

A

Indirect acting vasopressors, such as ephedrine, partially rely on endogenous catecholamines stores in the post synaptic sympathetic neurons and are therefore less effective.

33
Q

With the combitude, if the tip is placed in the esophagus can the lung be ventilated

A

Yes

34
Q

Should be release when placing the combitube?

A

Cricoid pressure.

35
Q

At what point during laparoscopy cholecystectomy is a gas embolism most likely to occur?

A

Initial Abdominal insufflation

36
Q

Gas embolism creates what?

A

air lock in the right heart and obstructs forward flow

37
Q

Signs and symptoms of gas embolism

A
Decrease EtCO2
Increase EtN
Increase PAP
pulmonary edema
Decrease BP,
38
Q

Mill wheel murmur is associated with

A

Gas embolism

39
Q

Most sensitive indicator of gas embolism

A

TEE

40
Q

Aging what happen to lung elastic recoil, what is the implication

A

Lung elastic recoil is loss leading to an Increased lung compliance. Lung elastic recoil is vital in maintaining airway diameter. Losing that ability lead to collapse of the lung prematurely. Causes trapping which increases RV

41
Q

2 first signs of PE

A

Precipitous fall in EtCO2

Tachycardia

42
Q

Most of the reported cases of retrograde intubation described its use in patient with

A

Cervical spinal injuries.

43
Q

This block anesthetize the vocal cords prior to an away intubation?

A

transtracheal

44
Q

This reflex forces LA on the vocal cord during a transtracheal block?

A

cough reflex

45
Q

What is the most reliable method to reduce postop pulmonary compications

A

Smoking cessation.

46
Q

Anesthesia for VATS for removal of bullae preferred ventilation strategies? Why>

A

Small TV and High RR (it minimizes intra-alveolar pressures, HFJV is an alternative to PPV)

47
Q

They are large air-filled spaces in the lung that result from damage to normal alveolar tissue?

A

Bullae

48
Q

If bullae are ruptured, it can lead to ?

A

Pneumothorax
Tension pneumothorax
Cardiovascular collapse

49
Q

To reduce the risk of rupture bullae the patient should be allowed to

A

Spontaneously ventilate until the chest is opened.

50
Q

This ventilation can increase tension and may result in rupture of the bullae>

A

Positive pressure

Q

Unilateral vagus nerve injury lead to

A

Hoarseness

52
Q

Bilateral vagus nerve injury lead to

A

Aphonia

54
Q

Bilateral External branch of the SLN injury

A

Hoarseness, easily fatigue

55
Q
