Q

During anesthesia, what causes patients to need airway or ventilatory support?

A

Assistance maintaining a patent airway and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function.

25
Pediatric adverse reactions are reduced with procedures that last?
Less than 1 hour
26
It is essential to preoperatively assess for ____ in pediatric patients to reduce the risk of airway compromise
Respiratory Infection -fever, snoring, sputum production, cough

What is the initial bolus dose of propofol?
0.5-1 mg/kg
29
What age group is at the highest risk of pediatric adverse events?
Less than 5 years old
30
Do geriatrics have an increased or decreased affinity for lipid soluble agents?
Increased and have a decreased metabolic rate
31
Geriatrics are more or less likely to experience delirium and post-operative cognitive deficits.
More!
32
How does thermoregulation change in geriatrics?
decreased thermoregulation
33
What two medications are preferred for cardioversion
propofol or etomidate for low EF
34
What are some anesthetic requirements for cardioversion?
NPO Oxygen, Monitors, Resuscitation equipment
35
What kind of sedation is preferred for cardioversion?
Moderate to Deep Sedation or a Room Air General Muscle Relaxant NOT needed.
36
What medications need to be avoided during RadioFrequency (RFA) Cryoablation
Avoid Lidocaine (can mask arrhythmias) Inhaled Volatile Gases (PA occluded during ablation)
37
What anesthetic considerations are needed for RadioFrequency (RFA) Cryoablation
-Esophageal temp probe: risk for thermal injury with LA ablation -Artline, vasoconstrictor, Inotropes -Need patient to remain very still
38
What can go wrong with a transeptal ablation technique?
Puncture LV and cause tamponade
39
In the geriatric population, a MET score greater than ____ is a good predictor they will be able to handle anesthetic from a cardiac standpoint
METs of 4 or more
40
RadioFrequency (RFA) or Cryoablation is usually accessed through?
the groin
41
What sort of anesthesia is usually performed for RadioFrequency (RFA) or Cryoablation
Local/MAC you could do TIVA or General
42
During RadioFrequency (RFA) or Cryoablations, should the patient be anticoagulated?
Yes, often with heparin. Check frequent ACTs and then reverse with protamine (usually 10mg)
43
What can happen if you give protamine too quickly?
Can tank blood pressure
44
What must be covered for radiation safety during RadioFrequency (RFA) Cryoablation?
Thyroid, long bones, reproductive organs, and EYES if you are in frequently

Why do we do ERCPs?
Biliary/Pancreatic Duct obstruction or drainage Unexplained jaundice, abnormal CT Biopsy Mapping pancreatic duct Sphincter of Oddi
50
What position are patients in for ERCPs
Endoscopically and in the prone position
51
