Paravertebral Block for Percutaneous Radiofrequency Ablation of Liver Lesions (TPVB)

August 22, 2024 updated by: Massimiliano Carassiti, Campus Bio-Medico University

Evaluation of the Analgesic Efficacy of the Ultrasound Guided Thoracic Paravertebral Block for Percutaneous Radiofrequency Ablation of Liver Lesions

Percutaneous radiofrequency ablation of liver lesions causes patients acute pain during and after the procedure. During the procedure patients need deep sedation and cannot be collaborative. Furthermore post-operative analgesia is necessary. The aim of this study is to evaluate if the ultrasound-guided paravertebral block (TPVB)with a single injection can provide anesthesia and post-operative analgesia in these patients.

Detailed Description

The purpose of this study is to evaluate if single injection TPVB, ultrasound guided, ENS assisted, is advantageous compared to deep sedation (DS)in patients undergoing percutaneous radiofrequency ablation of liver lesions with respect to post-operative analgesia (at rest and in movement)and vomiting. Furthermore we collect data on operator and patient satisfaction.

In this study patients are randomly divided into two groups (20 patient each): TPVB and DS. In TPVB group the block is performed in lateral position at level of T7 with bupivacaine 5mg/ml. In DS group the procedure is conducted under local and intravenous anesthesia, and a post-operative analgesia is assigned. Data on patient, on procedures (duration, number and position of lesions etc.), complications with the anesthesiological technique are collected. The intensity of post-operative pain is assessed at 3-6-12 and 24 hours after procedure in both group using VRS pain scale at rest and in movement. Any concomitant event like nausea, vomiting, respiratory complications etc are recorded.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intensity of postoperative pain after radiofrequency ablation of liver lesion
Time Frame: first 24 post-operative hours
Intensity of postoperative pain after radiofrequency ablation of liver lesion is evaluated in both groups using VRS of pain at rest and in movement after 3-6-12-24 hours from procedure.
first 24 post-operative hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of complications
Time Frame: From procedure to 24 hours

From procedure to 24 hours
Consumption of post-operative opioid
Time Frame: Within 24 post-operative hours
We evaluate if there is differences in consumption of opioid in the two groups
Within 24 post-operative hours
