Myotubular Trust was invited to participate in an energetic ENMC workshop on Mouthpiece Ventilation between 6-8th March 2020 which was organised by recognised leading experts in the field of respiratory medicine.
Together with 21 other professionals and patient organisation representatives from Europe, USA and Canada our aim was to focus on, and develop, best practice guidelines for the use of mouthpiece ventilation (MPV) in patients with neuromuscular disorders (NMD’s). Despite some delegates being unable to travel due to restrictions around the Covid-19 (Coronavirus) the meeting was successfully attended – physically and virtually!
Please scroll down for the lay report in English (other languages to follow). A full report will be published in Neuromuscular Disorders.
We would like to thank members of our patient community for providing us with their personal experiences of using MPV which was hugely helpful in preparing practical recommendations for our professional colleagues around this currently under-utilised form of ventilation.
This lay report can also be found on the ENMC website.
Respiratory insufficiency and pneumonia are primary causes of mortality and comorbidity in many NMDs. Studies show mechanical ventilation improves symptoms, gas exchange, quality of life and survival in NMD’s. Ventilatory support is usually offered via non-invasive techniques such as the use of a nasal or full-face mask during sleep. As the disease progresses, daytime ventilatory support becomes necessary. In some conditions, tracheostomy may be proposed when non-invasive strategies are no longer possible (ventilator dependence, severe bulbar insufficiency or mask related complications). An alternative to having a mask on the face during the daytime is to receive ventilation via a mouthpiece ventilation (MPV). Currently there is no consensus with regards to the timing, equipment or settings for the use of MPV in NMD’s.
In order to have a up to date information on current worldwide practice of the use of MPV, a pre workshop survey was sent to individuals working with NMD’s. The survey gathered information around current practice i.e. which countries/regions/type of hospital utilise MPV well, to identify the preferred mode, re-imbursement and aim of MPV delivery and identify any other perceived barriers to MPV.
During the ENMC workshop, there were dynamic discussions between clinical researchers, clinicians and patient representatives on issues related to MPV in order to improve the understanding and formulate recommendations and an algorithm to produce a consistent approach to MPV in individuals with NMDs.
Based on the survey and the experience of the delegates, concluded that MPV is currently underutilised. The attending experts discussed barriers and limitations to the provision of MPV including lack of understanding around the equipment required, the ventilation modes and settings. There are differences between countries regarding provision of MPV and its funding. Several bench studies were described to state the knowledge of technical issues, physiological aspects and ventilator alarms. The workshop group expressed their expectations that industry should develop further dedicated portable devices, modes and equipment for the MPV.
Enthusiastic discussions were facilitated with regards to the physiology of MPV, how to initiate, and monitor MPV. These sessions were based on the available evidence, clinical experience and expertise. The participants and MPV users were in agreement that MPV has several advantages for example, for speaking, eating, swallowing, and coughing. MPV has a huge impact on quality of life as it allows mobility and decreases social isolation as there is not mask on the face acting as a barrier to social inclusion. However, issues of safety and caregiver training were highlighted and recommendations and teaching tools were devised to support this. In further discussions, both the cost/benefit of this technique were explored along with what individuals with NMD’s would benefit the most.
During the workshop, treatment protocols and algorithms were prepared to provide practical recommendations and detailed information about the technique, and answer key questions about when to start; what ventilator; what mode; what mouthpiece; what patient; what monitoring, and follow up is required for individuals using MPV. The attendees hope that this will support clinicians to initiate individuals with MPV and have excellent outcomes.
