Summary

It is known that nociceptive afferences in visceral pain and visceral disorders increase sensitization in subjects suffering from fibromyalgia. These patients use to present visceral comorbidities. Those comorbidities include that of peridiaphragmatic organs, which are supplied by the phrenic nerve among other innervations. It is known that peridiaphragmatic organs trigger referred pain in the neck area, via the phrenic nerves. So, the phrenic nociceptive afferences can be contributing to enhance the state of sensitization in fibromyalgia. This study aims to analyze the ability of phrenic nerve infiltration to diminish sensitization in subjects suffering fibromyalgia, by means of a randomized controlled trial.

Conditions

  • Fibromyalgia

Interventions

DRUG

Bupivacain

The experimental intervention will consist of ultrasound-guided anesthetic blockade of the phrenic nerve at the laterocervical supraclavicular level with 1 ml of lidocaine without vasoconstrictor 2% to infiltrate the skin and 3ml of bupivacaine without vasoconstrictor 0.25% for neural blockade, making the local anesthetic surround the nerve between the anterior scalene muscle and the sternocleidomastoid muscle.

OTHER

Placebo (physiological saline serum infiltration)

The placebo intervention will be similar in relation to 2% lidocaine without vasoconstrictor for the skin, but an ultrasound-guided puncture will be performed at the level of the subcutaneous cellular tissue by injecting 3 ml of physiological saline.
