Anesthesia Lab II: Lecture 3 - Induction Flashcards
(17 cards)
What does MSMAID stand for in induction of anesthesia?
M = Machine
S = Suction
M = Monitors
A = Airway
I = IV set-up
D = Drugs
MSMAID is a mnemonic to remember the essential preparations needed before induction.
What are the 5 ASA Standard Monitors used during induction?
- Pulse Ox
- BP Cuff
- EKG Leads
- Capnometer
- Temperature
These monitors help ensure patient safety and vital sign monitoring during anesthesia.
What flow rate of oxygen should be used during preoxygenation?
> 10 L/min
Preoxygenation with high-flow oxygen helps to maximize the oxygen reserve before induction.
What is the first drug typically administered during the induction process?
Versed
Versed is a sedative often given in the preoperative area before the patient is brought to the OR.
How much Fentanyl is usually given for most general cases?
50-100 mcg (1-2 cc’s)
Fentanyl is an opioid analgesic used to provide pain relief during induction.
What is the typical dosage of Propofol for induction?
2 mg/kg
Propofol is the preferred agent for induction due to its rapid onset and short duration of action.
What test is performed to check if the patient is asleep?
Eyelash Reflex Test
This test involves lightly running a finger across the patient’s eyelashes to assess responsiveness.
What should be done when the patient stops breathing?
Begin mask ventilation
Mask ventilation is initiated to ensure adequate oxygenation until paralysis is achieved.
What is the purpose of administering a muscle relaxant during induction?
To facilitate intubation by relaxing pharyngeal muscles
Muscle relaxants allow for easier placement of the endotracheal tube.
What is the dosage of Rocuronium for complete paralysis?
0.6 mg/kg (Max 50 mg)
Rocuronium is a neuromuscular blocker used for intubation; higher doses may be used for rapid sequence induction.
What is the first step after administering the muscle relaxant?
Mask ventilate the patient until the Rocuronium takes effect
This ensures that the patient is adequately ventilated prior to intubation.
What is the purpose of verifying correct ETT placement?
To ensure bilateral breath sounds and proper ventilation
This is critical to confirm that the tube is correctly positioned in the trachea.
What is 1 MAC in anesthesia?
The minimum alveolar concentration at which 50% of patients won’t respond to painful stimuli
This measurement helps determine the appropriate concentration of anesthetic agent to use.
What is the recommended total fresh gas flow (FGF) during anesthesia?
2 L/min
A balanced FGF helps maintain adequate ventilation and prevents diffusion atelectasis.
What is the purpose of administering antibiotics immediately before incision?
To prevent surgical site infections
Commonly administered antibiotics include Ancef, usually in doses of 1-2 g.
Fill in the blank: The APL valve must be ______ during mask ventilation.
partially closed (~20 cmH2O)
This allows for effective ventilation while preventing excessive pressure in the airway.
What should be checked to assess the patient’s neuromuscular function before surgery?
Train of four (aka ‘twitches’)
This test assesses the degree of neuromuscular blockade and ensures readiness for intubation.
