Strauss Emergency Flashcards
What is the protocol for an endotracheal tube?
- Induce to unconscious with Propofol or Brevital (barbiturates)
- Oxygenate the patient
- Paralyze with succinylcholine (depolarizing muscle relaxant)
- Place endotracheal tube using laryngoscope
- Patient breathes Sevoflurane or Isoflurane
General anesthesia puts the patient into what stage of anesthesia?
Stage 3
When do many deaths associated with sedation occur?
During recovery
What is the biggest complication with sedation and GA cases?
Airway complication
While treating a medical emergency, what is important to ensure someone is doing while the team is treating the patient?
Recording what is doen when and how much
In any medical emergency, what must you think first?
- Airway
- Breathing
- Circulation
What is the best treatment for a medical emergency?
Prevent it (know your patient)
What is the term for the transient loss of consciousness as a result of a temporary decrease in cerebral blood flow with resultant ischemia?
Syncope
What is the most common emergency in the dental office?
Syncope
Why does syncope occur in the dental office?
Fight or flight kicks in but no muscle movement to pump blood to the brain so the patient faints
What is the demographic for syncope?
Males 16-35
What demographic do we normally not worry about syncope in from natural causes (e.g. could worry because of a medicine they take, but not worried that psychogenic will cause a syncope)?
Elderly
When does vasovagal response syncope normally occur?
Nonpsychogenic; due to hunger, dehydration, exhaustion. Vagus nerve slows heart.
Both psychogenic and non-psychogenic syncope are rare in what position?
Supine
What is the first sign of syncope?
Diaphoresis
What pulse should you check in a syncope patient?
Carotid because the BP will be in 30mmHg range will not be felt in wrist
What will be the pulse of a syncope patient?
Bradycardia 30-50 bpm
What is the ideal position for a syncope patient?
Astronaut - head and thorax in the same plane with feet elevated. Have the patient move their muscles to pump blood
How long should it take to recover from syncope?
20 seconds
What is the one relative contraindication to giving every patient oxygen in an emergency?
COPD patient who is oxygen driven. Dr Strauss says everyone gets oxygen in a medical emergency.
What is the most important drug in the emergency kit?
Oxygen
What are the 4 ventilatory statuses?
- Normal
- Decreased (e.g. seizure, airway compromised)
- Respiratory distress
- Ventilatory arrest or collapse
What is the best immediate method of ventilation that gives 16% oxygen?
Mouth to mouth
Mouth to mask ventilation gives how much oxygen?
16%, the same as mouth to mouth
What is the most efficient ventilator tool?
Endotracheal intubation
The chin thrust, neck tilt, and angle thrust airway opening maneuvers are designed to do what?
Bring the tongue forward off the pharyngeal wall
What is the term for a hollow plastic tube that physically separates the tongue from the pharyngeal wall and can attach to a bag valve mask set up?
Oral airway
Which is more well-tolerated in the awake patient: oral airway or nasal airway?
Nasal airway
What are 2 methods to get a surgical airway?
- Cricothyrotomy
2. Tracheostomy
Is a tracheostomy an emergency procedure?
No, it’s only for a long-term airway
What is an emergency airway for obstruction above the trachea?
Cricothyrotomy
What must be placed in cricothyrotomy to maintain the airway after the airway is opened with the blade handle?
Trach tube or anything solid and hollow
How long will the brain last without oxygen before unconsciousness?
6 seconds
What is the term for breathing that is more rapid or more deep than is required for normal maintenance of arterial PaO2, PaCO2, and blood pH?
Hyperventilation
What are the causes of hyperventilation?
Anxiety, pain, metabolic acidosis, hypercapnia, cirrhosis, organic CNS disorder
Palpitations during hyperventilation are what type of heart arrhythmias?
PVC
What are the neurologic manifestations of hyperventilation?
- Perioral parasthesia
2. Carpopedal spasms due to hypocalcemia
If a patient is hyperventilating, how should you position them and what should they do?
- Sit up
2. Have them breathe into a paper bad or hands
What is the term for acute paroxysmal chest pain as a result of coronary artery disease?
Angina
What is the term for angina associated with being at rest and having arrhythmias?
Prinzmetal angina
What are the steps for recognition and treatment of Angina?
- Patient will have dull heavy pain in the chest and radiating to left arm
- Give one of their nitroglycerine, wait 5 mins
- If first nitro doesn’t work, give 2nd nitro
- If 2nd nitro doesn’t work, the patient is having an MI until proven otherwise
If the patient is okay after the first dose of nitro, can you continue the appointment?
Yes
Can you give EPI to an angina patient?
Yes, 2 carpules
