Bupivicain vs Bupivicain Plus Dexamethasone in ESP Block for Post-op Analgesia

Comparison of Bupivicain Alone With Bupivicain Plus Dexamethasone in Erector Spinae Plane Block For Post-Operative Analgesia After Thoracotomy

Thoracotomy is a very painful procedure. Different treatment modalities are being utilized for post-thoracotomy analgesia including I/V NSAID, Opoids and Neuropathic medications. Other techniques commonly utilized include Thoracic epidural, Paravertebral block; but both are associated with significant failure rate and other complications. Ultrasound guided Erector Spinae Plane block is a new regional anesthesia technique that provides analgesia at multidermatomal levels acriss the posterior, lateral and anterior thoracic walls. The rational of my study is that it is a novel technique and studies with bupivicain alone are present but no study was found with bupivicain plus dexamethasone.
