  • Research summary

    Issue:
    - Optiflow (high flow humified nasal oxygen) is used in several settings frequently (ICU, during elective general anaesthesia- commonly here on the TOE list, in certain ENT patients, and more commonly now in obese or obstetric patients for preoxygenation)

    - to our knowledge no one has quantified the common complications associated with it (In November 2017 we performed a literature search using PubMed and Google using the search terms “high flow nasal oxygen” combined with “complications”, “side effects”, “nasal dryness” and “epistaxis”. We were unable to find any existing research that examined the days following HFNO use and specifically looked for minor side effects)

    - We have had anectdotal feedback from patients that they tend to experience respiratory symptoms post HFNO

    - we would like to determine how often this occurs and how long it lasts for which would be pertinent to consent, and informing patients prior to the procedure, and also serve to improve the literature on this up and coming technique.

    How:

    - prospective

    - aim of 30 people per group

    - we would intend two subgroups:

    1. volunteers who would agree to experience the optiflow whilst awake for the same period as those undergoing TOE

    2. those already undergoing TOE (as this is the most common and consistent group who have optiflow- about 4-5 patients per week)

    - we would conduct a a 7 day follow up survey to see if they had experienced complications (runny nose, nasal discomfort, sore throat, epistaxis), what their severity was and how long they lasted for
