Optimizing RSI Medication Timing * Much of recent airway research relates to RSI preparation and tube delivery: Resuscitate prior to intubation, improve hemodynamics to decrease risk of peri-intubation hemodynamic collapse, improve oxygenation to increase safe apneic time, positioning, ramping, airway alignment, bed up, head elevated, and bougie first approach etc. * Typical approach to RSI involves near simultaneous administration of induction and paralytic agents to rapidly result in ideal intubating condition. However, this approach often results in an induced but not paralyzed patient, causing difficulties with tube delivery as medication onset times differ: * Succinylcholine: 45-60 seconds * Rocuronium (1.2 mg/kg): ~60 seconds * Etomidate: 30-40 seconds * Ketamine: 30-45 seconds * Propofol: 20-25 seconds * As such, consider aiming for simultaneous onset rather than simultataneous administration of induction and paralytic agent. * In studies by Driver et al. 2019 and Catoire et al. 2024, administering paralytic prior to induction agent is associated with lower first attempt intubation failure. Bottom line => Consider administering paralytic first, then induction agent ~20-30 seconds later, ensuring simultaneous onset for optimal RSI while averting awake paralysis.
