Design outcomes

Primary

Measure	Time frame
The blood concentrations of the regional anesthetic agent was measured by using the liquid chromatography coupled with tandem mass spectrometry after Ultrasound-guided thoracic paravertebral block.	—

Secondary

Measure	Time frame
Blood pressure and heart rate were also measured both before and after administration of the study drugs. Ropivacaine or levobupivacaine as administered via the catheter at 6 mL/h, and fentanyl was administered via intravenous patient-controlled analgesia (CADD Legacy, Smiths Medical). The consumption of fentanyl over 24 h was measured.	—
