Noninvasive Support for Acute Respiratory Failure in Guillain-Barré Syndrome
Egypt80 participantsStarted 2025-08-01
Plain-language summary
This study will involve 70 adult patients with Guillain-Barré syndrome who have severe breathing problems. It will compare two types of breathing support: high-velocity nasal cannula (HVNC) (which delivers heated and humidified air at 35-60 L/min) and bi-level noninvasive ventilation (NIV) (which uses two pressure levels: inspiratory positive airway pressure (IPAP) 10-16 cmH₂O and expiratory positive airway pressure (EPAP) 5-8O). The main goal is to see how many patients can stop using non-invasive support without needing a breathing machine by Day 30. Other goals include how long it takes to stop using support, how comfortable patients feel, how long they stay in the ICU or hospital, how many days they can breathe on their own, and the number of deaths in 30 days. The main goal is to see how many patients can stop using non-invasive support without needing invasive ventilation by Day 30, while also looking at other factors like how long it takes to stop assistance, how comfortable patients are, how long they stay in the hospital, how many days they can breathe on their own, the number of deaths within 30 days, and their overall health.

* Pregnancy
* Severe comorbidity limiting prognosis.
* Declined consent
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
