"Delayed Sequence Intubation"

Jeffrey L Jarvis, John Gonzales, Danny Johns, Lauren Sager
STUDY OBJECTIVE: Peri-intubation hypoxia is an important adverse event of out-of-hospital rapid sequence intubation. The aim of this project is to determine whether a clinical bundle encompassing positioning, apneic oxygenation, delayed sequence intubation, and goal-directed preoxygenation is associated with decreased peri-intubation hypoxia compared with standard out-of-hospital rapid sequence intubation. METHODS: We conducted a retrospective, before-after study using data from a suburban emergency medical services (EMS) system in central Texas...

OBJECTIVE: Delayed sequence intubation (DSI) involves the administration of ketamine to facilitate adequate preoxygenation in the agitated patient. DSI was introduced into the Clinical Practice Guideline for Intensive Care Flight Paramedics in Victoria in late 2013. We aimed to describe the clinical characteristics of patients receiving DSI. METHODS: A retrospective analysis was undertaken of patients who received DSI between January 1, 2014, and December 31, 2016, during both primary response and retrieval missions...

Transient oxygen desaturation during emergency department intubation is an event with potentially devastating consequences. Pre-oxygenation is an important means of increasing a patient's oxygen reserve and duration of safe apnea prior to intubation. In the emergent setting, important modifications to pre-oxygenation techniques need to be considered to best manage critically ill patients. In this review, we discuss recent updates in pre-oxygenation techniques and evaluate the evidence supporting both commonly used and newly emerging techniques for pre-oxygenation, assessing nature and level of illness, the best delivery method of oxygen, using delayed sequence intubation in patients who cannot tolerate non-invasive pre-oxygenation and using apneic oxygenation via nasal cannula and non-rebreather mask during intubation...

Some patients are agitated and unable to tolerate conventional preoxygenation methods, including face mask oxygen or noninvasive positive-pressure ventilation. Sedation with ketamine for preoxygenation, also known as delayed sequence intubation, is a technique that can be used to achieve preoxygenation in this patient population. No complications of delayed sequence intubation have previously been reported. A 60-year-old woman presented with acute hypoxic respiratory failure. Despite application of high-flow oxygen (60 L/min) with a nonrebreather face mask, her oxygen saturation remained at 93%...

STUDY OBJECTIVE: We investigate a new technique for the emergency airway management of patients with altered mental status preventing adequate preoxygenation. METHODS: This was a prospective, observational, multicenter study of patients whose medical condition led them to impede optimal preintubation preparation because of delirium. A convenience sample of emergency department and ICU patients was enrolled. Patients received a dissociative dose of ketamine, allowing preoxygenation with high-flow nonrebreather mask or noninvasive positive pressure ventilation (NIPPV)...

BACKGROUND: The goal of preoxygenation is to provide us with a safe buffer of time before desaturation during Emergency Department intubation. For many intubations, the application of an oxygen mask is sufficient to provide us with ample time to safely intubate our patients. However, some patients are unable to achieve adequate saturations by conventional means and are at high risk for immediate desaturation during apnea and laryngoscopy. For these patients, more advanced methods to achieve preoxygenation and prevent desaturation are vital...
