Overview of Anesthesia Lecture 4 Flashcards
exam 2
What does MAC stand for in anesthesia?
Monitored Anesthesia Care
MAC is a type of anesthesia that allows patients to remain awake but relaxed during procedures.
What is the key characteristic of General Anesthesia?
Not arousable, often requires airway assistance, positive-pressure ventilation may be required, cardiac function may be impaired
General Anesthesia is used for major surgeries where complete unconsciousness is required.
What is the typical size range for Laryngeal Mask Airway (LMA)?
LMA 3, 4, 5 (4-5 is typical size)
The size of LMA used may vary based on the patient’s anatomy and age.
What position should a patient be in for optimal visualization of the glottic opening during intubation?
Sniffing position
This position helps align the airway and improve access during intubation.
What is the difference between MAC and Miller laryngoscope blades?
MAC is curved; Miller is straight
Each blade type has its specific use depending on the anatomy and situation.
Fill in the blank: The connector of an endotracheal tube initially is _______.
Loose, push in and twist to check the cuff
Ensuring the connector is secure is crucial for effective ventilation.
What should be done if a mass or polyp is seen during intubation?
See something, say something
Reporting observations can help in managing potential complications.
What is the purpose of preoxygenation in anesthesia?
To increase oxygen reserves before induction
This helps to prevent hypoxia during the induction phase.
What technique is becoming controversial for preventing passive regurgitation during Rapid Sequence Intubation (RSI)?
Cricoid pressure
While historically used, the efficacy and necessity of cricoid pressure are being debated.
What is the use of McGill Forceps in intubation?
Used for nasal intubation, be careful not to cut the cuff or grab the tip
These forceps help guide the tube through the nasal passage.
True or False: You can perform a procedure with just an LMA.
True
LMA can be sufficient for certain procedures like laparoscopic surgeries.
What is the role of the Bougie or tube exchanger in intubation?
Facilitates intubation, especially in difficult airway scenarios
It can help guide the endotracheal tube into the trachea.
What are the three categories of anesthesia mentioned?
MAC, Regional, General Anesthesia
What is a GlideScope?
A larger, bulkier, rigid stylet that allows for better visualization during intubation
It is particularly useful in difficult airway situations.
T/F- you should always lubricate an LMA before use?
True
Lubrication can facilitate easier insertion and reduce trauma.
Grade these airways:
grade 1
grade 2
grade 3
grade 4
