19
Q

True or false: ketamine suppresses the respiratory drive.

A

False

20
Q

What is one sedation-related side effect of ketamine that is unfortunate?

A

Sialorrhea

21
Q

Ketamine cannot be used in what patient population (two answers)?

A

Alcoholics (it’s hepatically metabolized)

Those with increased ICP

22
Q

What is adult dosing of ketamine?

A

0.5 - 1.0 mg/kg IV

Pushed slowly over 2 minutes

23
Q

Morphine typically lasts ___________.

A

3-5 hours

24
Q

What is the dosage of morphine for adults?

A

2-4 mg IV every five minutes to a max of 20 mg

25

A

0.4 - 2.0 mg IV every 3 minutes to a max of 10 mg

26
Q

What is the dosing of flumazenil?

A

0.2 mg IV every minute to a max of 1.0 mg

27
Q

Patients must be observed until they reach an Aldrete score of _______.

A

8

28
Q

What terms have replaced “conscious sedation”?

A 
Minimal sedation (awake anxiolysis) 
Moderate sedation (sleepy but arousable to light stimulation) 
Deep sedation (like a deep sleep that's hard to wake someone from)

These are all more mild than general anesthesia.

29
Q

What are some pediatric-specific diagnoses that may make a child have a difficult airway?

A
  • Airway malacia
  • Trisomy 21
  • Pierre Robin syndrome
  • Prematurity
  • Cerebral palsy
  • Behavioral patients (can become agitated with sedation)
  • Developmental delay
30
Q

What clinical features do you need to assess before performing conscious sedation?

A
  • PO status (generally prefer 8 hours for solids and 2 hours for clears)
  • Physical exam (jaw, neck, mouth, cardiac, and pulmonary systems at the minimum)
  • Recent illness
  • Recent sedative drug usage (e.g., have they taken opioids or benzodiazepines in the past 24 hours)
  • PMH
  • Allergies
  • Past experiences with sedation/surgery
  • ASA class
  • Vitals
  • Weight
31
Q

At what Mallampati score is consultation with an anesthesiologist recommended?

A

III - consider it

IV - absolutely need to do it

32
Q

No question here, just remember to position the person with neck slightly extended before administering sedation. This can save you from having them lose their airway when you give them the sedative.

A

..

33
Q

Because sedation is a procedure, it requires ____________.

A

a consent form

34
Q

Review the mnemonic SOBA-PEM-PID.

A

It’s a mnemonic you can use when you are either intubating a patient or doing procedural sedation:

  • Suction
  • Oxygen (tank, wall connector)
  • Bag-mask
  • Airway (laryngoscope, ETT, oropharyngeal airway)
  • Pulse-ox
  • End-tidal CO2
  • Monitor
  • Personnel (RT, Nurse)
  • IV access
  • Drugs (RSI meds, sedation meds, reversal agents, and code drugs)
35
Q

How full should an O2 tank be for procedural sedation?

A

At least enough to deliver 15 LPM for 60 minutes.

36
Q

When should you use an oropharyngeal airway?

A

Use an OPA when the head tilt, chin lift maneuver fails to relieve their obstruction.

37
Q

How do you size an OPA?

A

Just like a nasopharyngeal airway except it’s mouth to angle of the mandible instead of nose to angle of the mandible

38
Q

Elevated ETCO2 represents _____-ventilation.

A

hypo

Remember that ETCO2 indicates PaCO2.

39
Q

What three ID things must be said in a time out?

A

Name
DOB
MRN

40
Q

What’s the mnemonic to help you remember the components of the Aldrete scoring?

A

ARC3

  • Activity
  • Respiration
  • Circulation (BP)
  • Color
  • Consciousness
41
Q

In which circumstance can you not discharge a person with an Aldrete score of 8?

A

When they have received a reversal agent in the previous hour

42
Q

What is the pediatric sedation dose of ketamine?

A

2 mg/kg

You can give repeat doses of 0.5 - 1.0 mg/kg every 5 minutes as needed.

43
Q

How long does a person need to be NPO prior to ketamine for procedural sedation?

A

None

Because ketamine doesn’t interfere with airway reflexes there is no NPO time needed.

Propofol needs 8 hours for a fatty meal, 6 for a light meal, 4 for formula, 2 for clears
