Analgesia, Hepatectomy, Nerve Block
Conditions
Brief summary
This prospective, randomized study, control study aims to compare the analgesic effect, opioids consumption, quality of recovery, length of hospital stay and et al. between unilateral continuous quadratus lumborum block (QLB) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing hepatectomy with right J-shape subcostal incision.
Interventions
Inject local anesthetics in between quadratus lumborum and psoas major muscle with catheter insertion and continuous local infusion
The curved (C1-5) probe of Philip CX 50 Ultrasound Scanner is used for scan
* 0.6ml/kg 0.5% ropivacaine with 1:200,000 adrenaline given immediately after the correct position of the tip of the needle has been verified. * followed with 0.2% ropivacaine infusion at a rate of 0.125ml/kg/h given through the catheter inserted in between the quadratus lumborum muscle and psoas major muscle.
Bolus: 1-2mg, lock time: 10min, 1h limitation: 5-10mg. without background infusion.
