Summary
Patients undergo percutaneous radiofrequency ablation of hepatic tumors at Siriraj hospital
normally receive only intravenous sedative drugs which sometimes can not provide effective
pain control.
TPVB is suitable for unilateral operations. And it is increasing popular nowadays because of
using ultrasound guided which make it is more reliable and has less side effects especially
the severe one such as pneumothorax. To cover all nerve supply liver, we decided to use right
TPVB at T5-6, T7-8, and T9-10.
The aim of this study is to prove that TPVB can provide an effective pain control for
patients undergo liver RFA both at rest and movement (cough). We are going to measure the
pain score at recovery room and the effective pain control means patients has mild pain (pain
score less Phase:
