Impact of the Type of Interface in Neuromuscular Patients Treated With Nocturnal Noninvasive Ventilation (InterfaceNMD)

October 7, 2019 updated by: University Hospital, Grenoble

Impact of the Type of Interface in Neuromuscular Patients Treated With Nocturnal Noninvasive Ventilation: a Randomized Crossover Trial

Nocturnal Non Invasive Ventilation (NIV) is the reference treatment for chronic alveolar hypoventilation in patients with neuro-muscular diseases. NIV can be provided by using different types of interfaces: Nasal masks are the most frequent type of interface used at home but oronasal masks are used by at least 25% of neuro-muscular patients mainly because of persistent unintentional mouth leaks. However, oronasal mask may cause persistent upper airway obstructive respiratory events because of the mechanical constraint on the chin induced by the traction of the straps that may push the mandible posteriorly during sleep.

No randomized study has specifically addressed the question of the impact of type of interface in patients with neuromuscular diseases treated by nocturnal NIV.

The investigators hypothesize that:

  1. the application of oronasal mask may jeopardize the pharyngeal patency in patients already proned to upper airway obstruction;
  2. the use of a nasal mask may improve upper airway stability and NIV efficacy while reducing side effects.

Authors objective will be to compare the impact of nasal mask versus oronasal mask on NIV efficacy and side-effects. Eligible patients are those with nocturnal NIV and neuromuscular disease.

After a scheduled hospital visit, patients willing to participate will undergo in random order 2 unattended nocturnal polygraphies under NIV at home: one polygraphy with nasal mask; one with an oronasal mask. Each polygraphy ans side effects assessment will be performed after one week of familiarization with each mask.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 95 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Active Comparator: Usual interface

Patients which begin with their usual interface for one week, home polygraphy and side effect assessment at the end of the first week.

Switch for alternative interface, seven days familiarisation, second polygraphy and side effect assessment at the end of the second week.
Device: Switch of nocturnal NIV interface
  1. test the alternative interfaces (either a nasal mask for the patient used to oronasal mask or inversely an oronasal mask if the usual mask is nasal) during a one-hour diurnal NIV session. SpO2 (polygraphy), PtcCO2 will be monitored continuously during this diurnal session. Patients will use their usual NIV device prescribed at home. NIV settings will be adapted if needed.

  3. unattended nocturnal polygraphy under NIV (cf details below) will be performed at home with SomnoHolter® (Nomics, Liege, Belgium), synchronized with transcutaneous partial pressure in CO2 (PtcCO2) monitoring by SenTec V-Sign™ System.

Side-effects of Continuous Positive Airway Pressure (CPAP)
Time Frame: After one week with each type of mask

Side-effects reported by patients using a modified version of "Side Effect of CPAP inventory" (SECI) questionnaire.

A French translation will be done by two bilingual investigators (one medical doctor, one linguist).

This questionnaire consists of a list of 15 commonly reported side effects under CPAP.

For each side effect, the patient is asked to rate the frequency (0-5), magnitude (0-5) and perceived impact on adherence (0-5) on a five-point Likert-type scale.

Total score range : 0 to 225, with the higher score associated with the worst tolerance.

Range for each of the fifteen side effects: 0 to 15, higher values always represent a worse outcome (all subscales results are summed to compute the total score)
