Rapid Sequence Intubation Quiz

A surgical procedure performed through the cricothyroid membrane to secure an airway.

Difficult cricothyrotomies can occur due to factors such as prior surgery, presence of masses like abscesses or hematomas, anatomical challenges, radiation exposure, or tumors.

Prior surgeries can increase the difficulty of cricothyrotomy due to anatomical changes or scar tissue.

Masses like abscesses or hematomas can obstruct the cricothyroid membrane, hindering access.

Obesity, edema, or anatomical variations can make accessing the cricothyroid membrane difficult.

The entire glottis is visible, providing the clearest view.

The entire glottis is visible, but a portion of the arytenoids and vocal cords are obscured.

Only a small portion of the glottis is visible, making intubation challenging.

The glottis is completely obscured, requiring alternative airway management.

A mnemonic used to assess patients at risk for difficult intubation, focusing on external signs, jaw mobility, tongue size, airway obstruction, and neck mobility.

This step involves gathering necessary equipment, ensuring a clear airway, and assembling the RSI team.

This step involves providing 100% oxygen for 3-5 minutes to maximize oxygen stores in the body.

This step involves optimizing the patient's airway by adjusting positioning and using maneuvers like the jaw thrust or head tilt-chin lift.

This step involves administering a paralytic agent to relax the muscles of the airway, allowing for easier intubation, followed by an anesthetic agent to induce unconsciousness.

This step involves positioning the patient's head slightly extended and the neck neutral, ensuring proper alignment for intubation.

A clinical assessment tool used to predict the difficulty of endotracheal intubation.

The Mallampati Scale categorizes patients into four classes (I to IV) based on the visibility of structures in the oropharynx. Class I shows the most structures, indicating ease of intubation, while Class IV shows the fewest, suggesting difficulty.

Class I: Soft palate, uvula, fauces, and pillars are visible. Class II: Soft palate, uvula, and fauces are visible. Class III: Soft palate and base of uvula are visible. Class IV: Only hard palate is visible.

Higher class numbers on the Mallampati Scale (e.g., Class III and IV) indicate more difficulty with intubation due to restricted access.

The Mallampati Scale is used by clinicians to prepare for intubation and potentially implement alternative airway management strategies in case of difficulty.

A rapid sequence intubation (RSI) technique using the medications etomidate and succinylcholine. This procedure aims to quickly achieve intubation and secure an airway for patients requiring immediate airway management.

A medication used for induction of anesthesia, known for its rapid onset and short duration of action, minimizing cardiovascular effects.

A neuromuscular blocking agent causing temporary paralysis to facilitate intubation. It quickly and effectively relaxes the muscles, allowing for airway access.

The maneuver involves applying pressure to the cricoid cartilage to minimize the risk of aspiration during intubation.

A visual assessment of the glottis during laryngoscopy, categorized by the visibility of the vocal cords and the glottis, used to evaluate the difficulty of intubation. This assessment provides critical information for choosing the appropriate intubation technique.

This mnemonic is used to evaluate factors that can make bag-mask ventilation difficult, such as airway obstruction, obesity, and difficulty with mask seal.

This mnemonic helps evaluate potential difficulties in placing an extraglottic airway device by focusing on factors like limited mouth opening, airway obstruction, and a short distance between the chin and thyroid cartilage.

This factor in the ROMAN mnemonic refers to factors that impede airflow during ventilation, such as airway resistance or narrowing.

This factor in the ROMAN mnemonic considers factors that might obstruct the airway, such as obesity, obstructive sleep apnea, or a large tongue.

This aspect of the RODS mnemonic refers to situations where the mouth opening is limited or ventilation is restricted, potentially making it difficult to place an extraglottic airway device.

The initial stage of intubation where essential supplies are gathered, the airway is secured, and the team is prepared.

Administering 100% oxygen using a non-rebreather mask or BiPAP for at least 3 minutes before intubation to increase oxygen levels in the blood.

Optimizing the patient's airway by administering medication like albuterol, epinephrine, or terbutaline just before intubation to improve breathing.

The process of paralyzing the muscles with a drug like succinylcholine for easier airway access, then inducing unconsciousness with an anesthetic like ketamine.

The critical step of inserting the endotracheal tube into the trachea, confirming placement with end-tidal carbon dioxide monitoring, and immediately managing the patient after intubation.

The preparation phase involves gathering necessary equipment, ensuring a clear airway, and assembling the RSI team.

Preoxygenation maximizes oxygen stores in the body by delivering 100% oxygen for 3-5 minutes, improving outcomes in patients with compromised airways.

Preintubation optimization involves optimizing the patient's airway by adjusting their positioning and using techniques like jaw thrust or head tilt-chin lift.

Paralysis with induction involves administering a paralytic agent to relax the muscles of the airway, followed by an anesthetic agent to induce unconsciousness, allowing for safe and easy intubation.

Postintubation management involves providing sedation and analgesia to the patient, ensuring airway stability and comfort, and carefully monitoring for complications.

Succinylcholine should be avoided in patients with burns covering more than 10% of the body surface area, as it increases the risk of hyperkalemia, potentially causing cardiac arrest. This risk persists for at least 5 days after the injury and until the wounds are healed.

Succinylcholine should be used with caution in patients with crush injuries, as it can trigger hyperkalemia and fatal arrhythmias. This risk is greatest within the first 5 days after the injury and lasts until the wounds are healed.

Succinylcholine administration can cause hyperkalemia in patients with denervation, like stroke or spinal cord injury. This risk is highest within the first 6 months after the event.

Neuromuscular diseases like ALS, MS, and muscular dystrophy disrupt nerve and muscle function, increasing the risk of hyperkalemia after succinylcholine administration. This heightened risk is ongoing and requires ongoing monitoring.

Intestinal infections can cause hyperkalemia, and using succinylcholine in these cases can exacerbate the problem. The enhanced risk lasts for at least 5 days after the infection resolves.

Pre-oxygenation involves giving the patient 100% oxygen at a high flow rate for 3 minutes using a non-rebreather mask. This maximizes the oxygen level in their blood, ensuring a reserve even during intubation.

Pre-intubation optimization aims to improve the patient's airway before intubation by adjusting their position and using maneuvers like jaw thrust or head tilt-chin lift.

Paralysis with induction involves using a paralytic agent to relax the airway muscles, followed by an anesthetic to put the patient to sleep. This ensures smooth intubation without pain or resistance.

Positioning the patient's head slightly extended and with their neck neutral allows for a clear view of the airway during intubation.

Post-intubation management focuses on ensuring adequate blood circulation and oxygenation. This includes continuing fluid resuscitation and administering pressor agents as needed to maintain blood pressure and heart function.
