NCT00689234

Brief Summary

The purpose of the study is to investigate the impact of unilateral or bilateral diaphragm plication in a prospective randomised controlled way on symptoms, pulmonary function including gas exchange, respiratory muscle strength, exercise capacity and breathing during sleep in patients with proven uni- or bilateral phrenic nerve paralysis present for at least 1 year without any evidence of spontaneous recovery.

Study Arms (2)

A

PLACEBO COMPARATOR

At time of inclusion randomised in the "no intervention" arm (the subjects will be re-evaluated 6 months later and will get intervention at that time (cross-over protocol)

Procedure: diaphragm plication 6 months after inclusion

B

ACTIVE COMPARATOR

At time of inclusion the subject get the intervention

Procedure: diaphragm plication at time of inclusion

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Uni- or bilateral diaphragmatic paralysis due to phrenic nerve paralysis present for at least 1 year
  • With reduced VC, at least in supine position and no significant change in VC for at least 6 months
  • At the time of randomisation symptomatic patient, defined by one of the following symptoms: not able to sleep in supine position or exertional dyspnoea

You may not qualify if:

  • No informed consent obtained
  • Other disease that may interfere with the evaluation of pulmonary function or the exercise capacity: COPD, parenchymal lung disease on the thoracic X-ray, documented ischemic heart disease or left heart failure, active rheumatological disease, severe orthopaedic problems,....
  • Abnormal neuromuscular clinical investigation (apart from diaphragmatic dysfunction) and/or abnormal electromyography of the limbs compatible with generalized neuromuscular disease
  • Known diseases resulting in abnormal blood coagulation
  • Proven oncological origine of the phrenic nerve paralysis
  • Age below 18 yrs old
