31

Contraindications of Etomidate

Known to suppress adrenal cortisol production

32

Benefits of Ketamine

Stimulates catecholamine release
Bronchodilation

33

Contraindications of Ketamine

Elevated ICP
Elevated BP

34

When may Ketamine be an excellent induction agent?

Bronchospasm
Septic shock
Hemodynamic compromise

35

Benefits of Midazolam (Versed)

Potent dose-related amnesic properties

36

Contraindications of Midazolam (Versed)

Dose-related myocardial depression can result in hypotension

37

Benefits of Propofol

Bronchodilation

38

Relative Contraindication of Propofol

Dose-related hypotension

39

Benefits of Thiopental Sodium

Cerebroprotective and anti-convulsive properties

40

Contraindications of Thiopental Sodium

Potent venodilator and myocardial depressant
Relative: reactive airway disease due to histamine release
Acute intermittent and variegate porphyrias

41

Benefits of Methohexital

Cerebroprotective

42

Contraindication of Methohexital

Acute intermittent and variegate porphyrias

43

Neuromuscular Blocking Agents (Paralytics)

Succinylcholine
Vecuronium or rocuronium

44

Contraindications of Succinylcholine

Hyperkalemia
Neuromuscular disease
Ocular trauma
Malignant hyperthermia
Rhabdomyolysis
Stroke or burn >72 hours old

45

Reasons for Cricoid Pressure

Collapse the esophagus to prevent regurgitation of gastric contents
Facilitate visualization of vocal cords

46

Confirmation of Placement of ET Tube

ETCO2 monitor
Auscultation of breath sounds
Esophageal intubation detection device
CXR: can just tell how far tube is in

47

What color is the ETCO2 monitor on inhalation and exhalation?

I: purple
E: yellow

48

Postintubation Management

Secure ET tube
CXR to evaluate depth of tube and assess for barotrauma
Support BP
Mechanical ventilation

49

Indications for a Cricothyroidotomy

When patient has failed to be oxygenated adequately by all other possible methods and intubation has failed

50

Relative Contraindication of a Cricothyroidotomy

Young children due to shape of airway- may lead to subglottic stenosis

51

Step 1 of a Cricothyroidotomy

Identify the cricothyroid membrane by palpation

52

Step 2 of a Cricothyroidotomy

Horizontal stab incision through skin and cricothyroid membrane

53

Step 3 of a Cricothyroidotomy

Hook placed prior to removal of scalpel
Caudal traction used to stabilize larynx

54

Step 4 of a Cricothyroidotomy

Insert tracheostomy tube into the trachea

55

How does cardiovascular collapse occur?

Hypotension causes an increase in systemic vascular resistance and decreased tissue perfusion
Repeat until complete collapse
