Prospective Observational Study on the Analgesic Effectiveness of Blocking the Suprascapular and Axillary Nerves in Shoulder Arthroscopy.

Prospective Observational Study on the Analgesic Effectiveness of Blocking the Shoulder´s Anterior Capsule and the Suprascapular Nerve by the Anterior Approach Versus Blocking of the Suprascapular and Axillary Nerves by the Posterior Approach in Shoulder Arthroscopy.

The purpose of this study was to evaluate the analgesic efficacy of suprascapular and axillary nerve block for shoulder arthroscopy surgery

An observational study of paired cohorts, not randomized, was designed with the aim of comparing the postoperative analgesic effectiveness of two regional analgesic techniques: the shoulder anterior capsular block associated with the suprascapular nerve block performed via an anterior approach versus the suprascapular and axillary nerve blocks performed posteriorly in patients with shoulder surgery via arthroscopy in procedures that cause intense postoperative pain.

Inclusion Criteria:

• Patients over 18 years of age.
• ASA (Physical Status Classification System) I - III.
• Having been scheduled for shoulder arthroscopy surgery.

Exclusion Criteria:

Any contraindication for performing regional anesthetic techniques:

• Infection at the puncture point.
• Alteration of hemostasis.
• Allergy to local anesthetics.
• Patient refusal to participate in the study.
• Inability to evaluate postoperative pain.
• Known neuropathy of the operated limb.
• Patients who required conversion to open surgery.
