RSI Flashcards
(49 cards)
What are the main reasons a patient emerges from anesthesia?
Discontinuation of anesthetic agents (versed, fent, volatiles), stimulation (verbal, noxious), and rising CO₂ levels which trigger spontaneous ventilation
What is the primary objective of RSI?
Prevent pulmonary aspiration
How does rapid sequence induction (RSI) reduce the risk of aspiration?
By minimizing the time between loss of airway reflexes and securing the airway, and by using cricoid pressure to occlude the esophagus.
Name indications for RSI (think anyone who’s at risk for aspiration)
Trauma
Esophageal obstruction
NPO guidelines not followed
Acute abdomen and bowel obstruction
Active GI bleed or upper airway bleed
Pregnancy
Abdominal mass or ascites
Severe GERD
N/V
What is the purpose of cricoid pressure during RSI?
To compress the esophagus against the cervical vertebrae
Is the cricoid pressure maneuver (Sellick’s maneuver) always effective?
No—it may impair glottic view and 75% of people have an esophagus to the right of the trachea
What are major problems with cricoid pressure during intubation?
Improper pressure can worsen glottic view, making intubation harder
If the patient vomits, cricoid pressure can increase the risk of esophageal rupture**
What are some contraindications to cric pressure?
Airway trauma
Lack of properly trained assistant
Fractured larynx or cricoid
Active vomiting
Esophageal foreign body near cricoid
Esophageal disease
Cervical fracture near C6
Name complications of intubation
Dental trauma, esophageal intubation, laryngospasm, bronchospasm, right mainstem intubation, vocal cord injury
What is the most common cause of death related to airway management?
Pulmonary aspiration
When does bronchospasm occur?
During intubation or extubation
What increases the risk of bronchospasm?
Patients with reactive airway disease (RAD) like asthma, COPD
What are signs of bronchospasm during anesthesia?
High peak pressures, wheezing, poor bag compliance, desaturation, absence of tube fog
How do you treat a bronchospasm?
100% O2
Beta 2 agonist (albuterol)
Lidocaine IV or through ETT if intubated
Deepen volatile (if intubated)
IV atropine, epi (last option)
Fentanyl
Name extubation criteria
Adequate NMBA reversal (sugam)
TOF 4/4 with sustained 5 sec tetany
Vt and RR adequate to eliminate CO2
Strong hand grip
Strong cough
Sustained head lift>5 sec
Airway reflexes (swallow and tongue movement)
Maintain oxygenation/ventilation without stimulation*
What are important questions to ask before extubation?
Can I maintain a patent airway? Can I reintubate if needed? Are aspiration risks reduced?
What is the overall goal of extubation?
Smooth, atraumatic extubation
When can you extubate?
Either while deep, or awake
What patients would you NOT extubate deep?
Depends on patient history, aspiration risk, difficult intubation, OSA
What is the purpose of giving a positive pressure breath before extubation?
Clears secretions and helps push them away from the vocal cords
When should the ETT be gently removed during extubation?
Pull the tube on exhalation to ensure that secretions are projected away from cords
If you pull the ETT on inhalation, what does that put the patient at risk for?
Laryngospasm
What should be done immediately after removing the ETT?
Apply oxygen with PPV, and listen for breath sounds/mask fog
After extubation, what could hear crowing and turbulent sounds indicate?
Partially obstructed airway
