Clinical Trial Summary

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.

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.

Other	Satisfaction of patient and of the operator	We collect data on operator satisfaction during the procedure, and patients satisfaction at 24 hours after procedure	From the procedure to 24 hours later.
Primary	Intensity of postoperative pain after radiofrequency ablation of liver lesion	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	Incidence of complications	We record immediate complication such as PNX, vascular puncture etc, and post-operative complications such as nausea, vomiting, hypotension, etc, in both groups	From procedure to 24 hours
Secondary	Consumption of post-operative opioid	We evaluate if there is differences in consumption of opioid in the two groups	Within 24 post-operative hours
