The Impact of Suctioning on Oxygenation During RSI in the Emergency Department

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Rapid Sequence Intubation (RSI) is a common procedure in Emergency Departments (ED). However, it is a high-risk procedure and has been associated with significant complications including hypoxia, hypotension, airway trauma, aspiration, and death. Specifically, hypoxic episodes during intubation can lead to poor outcomes such as dysrhythmias, haemodynamic compromise, hypoxic brain injury and cardiac arrest, and is therefore of primary concern during any intubation procedure. Aspiration is a serious adverse event and potential cause of hypoxia during RSI and can lead to poor patient outcomes downstream of the procedure. The reported incidence of aspiration during RSI in the ED ranges from 3 to 8% in the ED population. In order to achieve an optimal view of the glottis and prevent pulmonary aspiration of fluids in the oropharynx, providers apply suction prior to and during laryngoscopy, using a Yankauer or large-bore suction catheter. There is currently significant variation in suctioning during laryngoscopy, with some providers using very little suction as needed to clear heavy fluids (judicious suctioning), while others utilise suction aggressively (lead with suction) and as a part of their routine laryngoscopy technique. Evidence suggests inline suction on already-intubated patients accelerates desaturation, but we are aware of no studies examining the impact suctioning has on the speed of desaturation during emergent endotracheal intubation. This pilot study aims to compare the effects of intermittent, as-needed "judicious" suctioning versus aggressive "continuous" (lead with) suctioning on oxygenation during rapid sequence intubation in the emergency department.
