Summary

Percutaneus radiofrequency ablation (RFA) of liver tumors causes acute pain during the periooperative setting. In order to facilitate tumor access, patient should collaborate with a surgeon during the procedurę, therefore should be conscious.

This study aims to assess the impact of a single shot thoracic paravertebral block (TPVB) on a patient's haemodynamic stability, patient's and operator's comfort and satisfaction during the operation and analgesia in the post-operative period.

Conditions

  • Liver Tumor

Interventions

PROCEDURE

thoracic paravertebral blockade

Anesthesia was performed under the ultrasound guidance: the Th8 spinous process was identified, then a probe was moved lateral to medial until two adjacent transverse processes and the pleura were visible. After anaesthetising the skin with 2ml of 1% lignocaine (Lignocainum hydrochlorici, WZF 1%), the Touhy needle 22G (Smith Medical)was introduced under the real time guidance. Once in the paravertebral space, 20ml of 0,25% bupivacaine (Bupivacainum hydrochloricum WZF 0,5%, Polfa Warsaw SA) was injected with an end point of a characteristic pleural displacement.

PROCEDURE

local anaesthesia

Local infiltration anaesthesia with 0.5% lignocaine 5ml (Lignocainum hydrochlorici, WZF 1%) was applied to the skin and the potential needle path of ablation.
