Rapid Sequence Intubation
RSI The use of medication to facilitate passing the
endotracheal tube Analgesics Sedatives Paralytics
CONTROLLED procedure Will take several minutes to accomplish Requires a team effort
The ultimate goal is to secure an airway without having the patient vomit and aspirate.

Indications for RSI
Impending airway obstruction Facial fractures…no excessive oral bleeding Facial burns…inhalation injury Expanding retropharyngeal hematoma
Excessive work of breathing Example…the exhausted asthmatic
Shock GCS <8 Persistent hypoxia (<90%)

2. Preoxygenate
3-5 minutes with 100% O2 bag mask to ensure adequate oxygen reservoir in lungs during apnea
Assure age appropriate fitting mask
![Page 8: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/8.jpg)
3. Pre-treatment
Laryngoscopy causes stimulation of afferentreceptors in the posterior pharynx,hypopharynx and larynx.
Reflexes can cause:– Increased intracranial pressure (ICP)– Stimulation of upper & lower respiratory tract
increasing airway resistance.– Stimulation of autonomic nervous system, with increase heart rate and BP (vagal stimulation cause decrease in pediatric!)
![Page 9: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/9.jpg)
Pre-treatment
Attenuate (weaken) normal physiologic &
pathophysiological reflex responses
caused by airway manipulation during
laryngoscope and insertion of an
endotracheal tube.
- Lidocaine
- Atropine
- Defasiculating agent
![Page 10: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/10.jpg)
Pre-treatment meds
Atropine – Treats brady response to SUX, and in young children.
Lidocaine – Helps decrease ICP associated with intubation.
Vecuronium (defasiculationg dose)- keeps muscles from fasiculating (twitching) when using “Succs”

4. Paralysis (with induction)
Check patency of line first! Make sure everyone is ready Give IV pushes rapidly and flush Anesthesia before paralysis! *Induction agent is followed immediately
by the paralytic without waiting to see if ventilation can be maintained

5. Placement of Tube
Position patient
• Do not bag unless SpO2 < 90%
• Sellick’s Maneuver (Cricoid pressure)
![Page 21: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/21.jpg)
Placement of tube
![Page 22: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/22.jpg)
Placement and Proof
Confirm tube placement
– ETCO2 – Bilateral breath
sounds – Absent epigastric
sounds
![Page 23: Rapid Sequence Intubation](https://reader035.vdocuments.net/reader035/viewer/2022081514/5681588c550346895dc5eaa4/html5/thumbnails/23.jpg)
Failed attempt
What if the intubation attempt is not
successful? 1st step = bag/mask ventilation for
support
Rescue Maneuvers – The first rescue from failed intubation is
bagging – The first rescue from failed bagging is better
bagging

6. Post-intubation Management
Secure tube ETCO2 Chest x-ray Long acting sedation (+/- paralysis) – Midazolam 0.2mg/kg – Propofol 25-50μg/kg/min Establish ventilator parameters
