HEPATIC TUMORS
Paravertebral block has been used as an effective perioperative analgesic approach in many types of surgeries, such as thoracic, breast, cardiac and abdominal surgeries [Open hepatectomy often causes severe pain due to its large incision and extensive surgical damage. Cases of paravertebral block use in hepatectomy have been reported [This study aimed to investigate the effects of intermittent bolus paravertebral block on analgesia and recovery in patients undergoing open hepatectomy for hepatic tumors. We hypothesized that intermittent bolus paravertebral block reduced postoperative 48 h cumulative intravenous opioid consumption. Intraoperative management, postoperative analgesia and recovery, and follow-up data were collected and compared between patients with and without paravertebral block. We present the following article in accordance with the CONSORT reporting checklist.
