Comparatore attivo: 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.

|
Sperimentale: 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.

Lasso di tempo: 6 assessments starting 5 minutes after nerve block and ending 30 minutes after nerve block.
|
Sensory level as assessed by temperature and pin prick test assessed every 5 min for 30 min after nerve block as defined as the patient returning to their bed.
