RSI
Rapid Sequence Intubation

2. Definition
RSI is the process of simultaneous administration of an
induction and a neuromuscular blocking agent to
Facilitate Tracheal Intubation And Is Preferred For
Emergency intubation
Aim: To intubate the trachea as quickly & safely as
possible

3. Indications for RSI
• airway protection and patency
• respiratory failure (hypercapnic or hypoxic),decrease
WOB.
• minimise oxygen consumption and optimize oxygen
delivery (e.g. sepsis)
• unresponsive patient, seizure, prevent secondary
brain injury.
• For humanitarian reasons (e.g. procedures) and for
safety during transport

4. Contraindications of RSI
 Airway Obstruction
 Allergy to Anaesthetic medications
 Severe oral or mandible trauma

6. 6 P’s of RSI
• Preparation
• Pre-Oxygenation with 100% oxygen
• Pre-treatment & Induction
• Paralysis +/- Cricoid pressure
• Placement of the tube
• Post intubation management

7. Preparation
Suction
— at least one working suction
Oxygen
— NRBM and BVM attached to 15 LPM of O2.
Airways
— 7.5 ET tube with stylet fits most adults, 7.0 for smaller
females, 8.0 for larger males, test balloon by filling with
10 cc of air with a syringe

8. — Stylet
—laryngoscope should be ready
— Backups – ALWAYS have a surgical cric. kit
available!
— have video laryngoscope if available & a LMA at
bedside
Pre-oxygenate – 15 LPM NRBM
Positioning
Monitoring equipment/Medications
— Cardiac monitor, pulse ox., BP cuff opposite arm with
IV ascess
— Medications for pre-treatment
End Tidal CO2

9. Pre-Oxygenation
Pre-Oxygenation
• Establish O2 reservoir
• Maximize time for intubation
• Prevent need for bag-mask ventilation
Methods:
• 3-5 minutes of 100% O2 via bag mask
• 5 Tidal capacity (5 Breaths)

10. Pre-Treatment
Pre-Treatment
• Mitigate adverse physiologic reactions to intubation
– Sympathetic “pressor response”
• Manipulation of airway, ↑ HR/BP,
– Bronchospasm
– Increased ICP
– Muscle Fasciculation
– “LOAD”

12. Induction
Given as rapid IV push immediately before paralysing
agent
• Facilitate LOC in one-arm-brain circulation time
minimize the time from LOC to intubation
• Should provide a rapid onset & a rapid recovery from
anaesthesia with minimal CVS & Systemic side effect.

14. Paralytics
Paralysis/NMB Agent
• Rapid onset of action to minimize risk of aspiration &
hypoxia
• Rapid recovery to facilitate the return of ventilation if
intubation fails
• Minimal hemodynamic & systemic effect
Wait for relaxation
- Do not bag unless hypoxic
- Insufflate air into the stomach & increase risk of

16. Technique
Cricoid Pressure:
Techniques
• The oesophagus is occluded by extension of the neck
& application of pressure over the cricoid cartilage
against the body of 5 cervical vertebra to obliterate
oesophageal
lumen
• Applied an assistant with thumb & finger at either side
of cricoid cartilage

18. Placement
Tube position is confirmed by:
• Direct visualization of ET tube between the vocal
cord
• Auscultation: equal air entry
• Capnometer: EtCO2

19. What if Intubation Failed???
What if the intubation attempt is not successful?
1st step = bagmask ventilation for support
Rescue Maneuvers
– The first rescue from failed intubation is bagging
– The first rescue from failed bagging is better bagging

20. Post Intubation Mx
• ECG
• SPO2
• NIBP/Art-line
• Capnograph
• Nasogastric tube
• CXR
• ABG Post intubation
• Maintainace of sedation (+/- paralysis)
– Midazolam 0.2mg/kg
– Propofol 25-50μg/kg/min
Establish ventilator parameters
