RSI is generally used for patients who have an increased risk of aspirating stomach contents into the lungs due to a current disease process. If not performed properly, or if the patient is unable to be intubated very rapidly 2 minutes or less, the patient could suffer extreme morbidity from hypoxia, hypercapnia or acidosis, or even death. Mnemonic: A mnemonic for performing RSI is the Eight- Ps Preparation: prepare all necessary equipment, drugs and patient basic airway management and Positioning Preoxygenation: with 100 oxygen, 3 to 5 minutes Premedication: Pediatric: Atropine 0.02 mgkg IV children 8 years minimum 0.1 mg, Adults: Lidocaine 1.5 mgkg IV head injury, asthma Push the sedative: Etomidate, midazolam or ketamine Paralyze: suxamethonium, vecuronium or rocuronium Pass the tube: visualize the tube going through the vocal cords Proof of placement: Use EID, check breath sounds, CO2 detector Post intubation care: secure the tube, ventilate
