Post Operative Pain, Acute
About this trial
This is an interventional treatment trial for Post Operative Pain, Acute focused on measuring regional anesthesia
Eligibility Criteria

Exclusion Criteria: Patient's refusal. Patients with major spine deformities. Disruption of the local anatomy, secondary, for instance, to the presence of chest drains or surgical emphysema, resulting in difficulty in ultrasound interpretation and distortion of tissue planes. Patients with bleeding disorders and coagulopathy. Infection at the injection site. Known allergy to local anesthetics. Patients with pre-existing myopathy or neuropathy.
