Personalized Quantum Sonotherapy in Regional Anesthesia

Study Overview
=================
Brief Summary
-----------------
The objetive of the study is to evaluate the effect of personalized quantum sonotherapy on the level of anxiety and pain in outpatients schedule for orthopedic surgery under regional anesthesia in a second level center. The investigators believed that personalized quantum sonotherapy could reduce the levels of anxiety and pain before and after surgery evaluated through hemodynamic variables and scales for pain (analogous visual scale) and anxiety (STAI Spielberger anxious state questionnaire).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Personal quantum sonotherapy group<br>Patients who will listen through MP3 devices the personalized quantum sonotherapy previously created through a especialized software, before the application of regional anesthesia. | Procedure: Personalized quantum sonotherapy<br>* Quantum sonotherapy is an alternative non-pharmacological treatment that effects a molecular reorganization that occurs after the sound stimulus. The audible words and their waves have the ability to generate vibrations and stimulate the psycho-neuro-endocrine chain, independent of the semantic meaning of the words. It is an alternative therapy that uses non-musical sound waves.<br>|
| Placebo Comparator: Control group<br>Patients will wear headphones but without playing the personalized quantum sonotherapy | Procedure: Placebo<br>* Headphones will be place in patients without playing quantum sonotherapy<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain | To assess the effect of personalized quantum sonotherapy on the level of pain of patients taken to orthopedic surgery under regional anesthesia through pain score visual analoge score (VAS). VAS ranges from 0 to 10 being 0 no pain an 10 the worst pain ever felted. It would be measured before and after placing de sonotherapy, 24 and 48 hour after surgery. | 48 hours (From the moment before surgery when the sonotherapy is apply until 48 hours after surgery) | 
| Anxiety | To assess the effect of personalized quantum sonotherapy on the level of anxiety of patients taken to orthopedic surgery under regional anesthesia through anxiety score Questionnaire of anxious state STAI (Spielberger). STAI is a score to meausre anxiety, it has 20 questions each one with a possible value from 0 to 3 points. Total score is evaluated adding each score for each question, and it goes from 0 to 60 points, being 60 de higest score for anxiety. It would be measured before and after placing de sonotherapy, 24 and 48 hour after surgery. | 48 hours (From the moment before surgery when the sonotherapy is apply until 48 hours after surgery) |
