4

What is the most important bit to anesthesia?

Maintain physiology

5

What are the three indications for putting in an endotracheal tube?

1. Patent airway
2. Control airway if paralysis
3. Improve ventilation/oxygen

6

What are mallampati classes? (1-4/)

1= tonsillar pillars, soft palate, and uvula are visible
2 = Uvula at base of tongue
3= Only soft palate visible
4 = Only base of tongue and hard palate visible

7

What are the oral findings that may complicate intubation?

Macroglossia
Loose or prominent dentition

8

What is the thyromental distance?

3 fingers from lower border of mandible to thyroid

9

Greater than what diameter of the neck may indicate difficult intubation?

18 in

10

Why do you oxygenate pts prior to intubation?

Denitrogenation

11

What are laryngeal mask airways? What is the issue with these?

***

There is nothing to stop regurgitation

12

What is the miller blade that is used for intubation?

Straight blades

13

What is the MacIntosh blade?

Curved blades for intubation

14

What is a glidescope?

Camera with a laryngoscope

15

What is the position of the head and neck when intubating?

Neck flexed, head extended

16

Laryngoscope is placed in the mouth how?

Directed toward the right tonsillar pillar and base of the tongue

17

What are the five things you look for when intubating someone?

1. Chest rise
2. Steam in the tube
3. Bilateral breath sounds
4. Sustained tidal ETCO2
5. PO2 stays above 92%

18

What are the indications for an epidural?

Surgical procedures
C sections
Cath placement

19

What are the absolute contraindications to epidurals? (5)

Patient refusal
Localized infection
Sepsis
Coagulopathy
Raised IC pressure

20

Why are anticoagulants a contraindication to epidural?

Can cause epidural hematoma

21

Why is hypovolemia a relative contraindication to epidurals?

Will cause lower BP

22

What is the needle used for epidurals?

Touhy needle

23

How do you tell when you're in the right space for an epidural?

Loss of resistance once past the ligamentum flavum

24

Why is there epi in the sample dose of an epidural?

Will cause tachycardia, and indicate if you're in an artery/vein. (could cause arrhythmias if inject lidocaine)

25

Intrathecal blocks are also called what?

Spinal blocks

26

What are the contraindications (5) for intrathecal blocks?

Same as for epidurals

27

L3/L4

28

What spinal level does the spinal cord end?

L2/3

29

Headache with movement after an LP indicates what?

Hole in the thecal sac, causing a loss of CSF

30

Why are smaller needles used for intrathecal injections?

Lower risk for headaches

31

What happens if a pt jumps with an intrathecal injection?

Move back--you're in the cauda equina

32

What are the indications for a central line?

Measure right sided heart filling pressure

Drug/fluids

33

If you have to remove an air emboli in the right atrium, what type of line will you use?

Central line

34

What are the common sites of central lines?

Right IJV
Left subclavian

35

How can you find the IJV?

Between the SCM heads

36

Where is the carotid relative to the IJV?

Just medial

37

How should you aim your needle with inserting a needle into the IJV?

Aim at the ipsilateral nipple

38

What are the guide wires used for?

***

39

How is the needle inserted in the subclavian vein?

At the outer 1/3 of the clavicle inferiorly, and directed towards the sternal notch

40

What is the complication of guide wires in the heart with central lines?

Arrhythmias
Pericardial tamponade

41

Why is the pt placed in the trendelenburg position with central line placement?

reduces risk of air embolism

42

What are the indications for arterial lines?

Monitor beat to beat blood pressure
BG draws

43

When are femoral art lines indicated?

WHen peripheral arteries are vasoconstricted secondary to meds

44

What are the complications with arterial lines? (4)
