Conditions
Brief summary
This study was a prospective, randomized, controlled, and double-blind trial. Major assessments were made during the operation and 48 h postoperatively.
Detailed description
The prime outcomes were the time in minutes from leave the postoperative care unit to the first patient-controlled intravenous analgesia press.The secondary outcomes were to compare the following: (1)blood concentrations of ropivacaine was measured at 0.5 h, 1 h, 2 h, 3 h, and 24 h after paravertebral nerve block; and (2) the patient's intraoperative opioid use, phenylephrine use, fluid intake, urine output, dry mouth score, and 24 h and 48 h visual analogue scale.
Interventions
combination of ropivacaine and dexmedetomidine 100 ug every time
combination of ropivacaine and dexamethasone 10mg every time
block with only ropivacaine
