Brief summary
Anxiety is an emotional disorder. It's a painful concern caused by uncertainty. It is a complex phenomenon misunderstood in spite of medical progress. Relaxation is a technical for reduce anxiety and is effective and safe. Previous study demonstrated the impact of session relaxation on the autonomous nervous system by the heart rate variability. Primary objective of this new study is to demonstrate a link between heart rate variability and reduced anxiety during relaxation session.
Detailed description
It is monocentric, prospective and interventional study. This study will be proposed at the patients who will have an orthopedic surgery in full hospitalization. These patients are anxious because of surgery too. The day before surgery anesthetist save heart rate variability and value of the partial pressure of carbon dioxide during relaxation session.
Interventions
OTHERrelaxation session
During relaxation session, patients anxious will have three electrodes for save heart rate variability and a sensor for save value of the partial pressure of carbon dioxide. Before and after relaxation session, patient evaluates his anxiety by visual analogue scale (VAS) and State-Trait Anxiety Inventory (STAI-Y).
