Comparison Of Ultrasound-Assisted Paravertebral Block And Traditional Paravertebral Block For Pain Control After Thoracic Surgery, A Prospective Randomized Trial
Comparison Of Ultrasound-Assisted Paravertebral Block And Traditional Paravertebral Block For Pain Control After Thoracic Surgery, A Prospective Randomized Trial
The overall purpose of this research study is to compare the effectiveness of ultrasound assisted paravertebral block placement versus traditional "blind" technique for postoperative analgesia following thoracotomy or visually assisted thoracoscopic surgery.
The purpose of this project is to determine if there is a difference between paravertebral block performed with ultrasound assistance and paravertebral block performed with traditional technique in terms of twenty - four hour hydromorphone (dilaudid) consumption and visual analogue pain scores at rest or with deep breathing at twenty - four hours. This study will determine if ultrasound technique used for placement of paravertebral catheter facilitates safety of paravertebral catheterization and improves therapeutic effect of paravertebral blockade for pain control after thoracotomy. The investigators will also examine if ultrasound assisted paravertebral blockade improves pulmonary status in post-thoracotomy patient.
