Ultrasound-Assisted Paravertebral Block v. Traditional Paravertebral Block For Pain Control
17. srpna 2018 aktualizováno: Anna Uskova, University of Pittsburgh
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.

Detailní popis
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.

Aktivní komparátor: Traditional approach paravertebral nerve block
After final needle placement, a hanging drop technique will be used to rule out intrapleural placement while the patient inhales and exhales deeply.
After correct needle placement, 10 mL of 0.5% Ropivacaine will be injected incrementally through each needle after negative aspiration, followed by insertion of the nerve block catheter to a depth 5 cm beyond the tip of the needle.
An additional 10 mL of 0.5% Ropivacaine will then be injected in 5 mL increments with negative aspiration in between, through the catheter yielding a total activation dose of 20 ml of 0.5% Ropivacaine.
The catheter will be secured with Steri-strips and a transparent occlusive dressing.

|
Experimentální: Ultrasound assisted paravertebral nerve block
The 22 gauge catheter will be threaded through the needle and placed at previously found distance to paravertebral space on obtained ultrasound image.
An additional 10 ml of 0.5% Ropivacaine will be administered through the catheter yielding a total activation dose of 20 ml of 0.5% Ropivacaine.
The catheter will be secured with Steri-strips and a transparent occlusive dressing.
