NCT07823244

Brief Summary

The goal of this clinical trial is to learn whether an intravenous lidocaine infusion (IVLI) works as well as a thoracic paravertebral block (TPVB) - the current standard nerve-block technique - for improving recovery after breast cancer surgery. It will also learn about the safety of both approaches. The main questions it aims to answer are: Does IVLI provide a similar quality of recovery (measured by the QoR-15 score at 24 hours) as TPVB? Does IVLI control pain during the first 24 hours after surgery (measured at rest and with arm movement) as well as TPVB? Participants will: Undergo their planned breast cancer surgery (mastectomy or breast-conserving surgery with sentinel lymph node biopsy) under general anaesthesia, along with either the TPVB injection or the IVLI infusion, assigned at random Attend a preoperative visit the day before surgery to learn how to use the pain and self-quality-of-recovery questionnaire (QoR-15) Fill out a QoR-15 once a day for the first 48 hours after surgery Participants' pain score in hospital recorded during the first 48 hours after surgery, with rescue pain medication available if needed

Study Arms (2)

TPVB

ACTIVE COMPARATOR

US guided TPVB

Procedure: TPVBDrug: IV placebo infusion

IV LI

EXPERIMENTAL

IV Lidocaine infusion

Drug: IV Lidocaine infusionProcedure: sham subcutaneous infiltration

Interventions

TPVBPROCEDURE

Single shot thoracic paravertebral block with 0.5% Ropivacaine plus adrenaline 5 mcg/ml (total mixture 25 ml)

TPVB

Patients receiving IV Lidocaine infusion of 1.5 mg/kg in 10 mins then continue 1.5mg/kg/h (= 0.075ml/kg in 10 mins then 0.075ml/kg/h) intraoperatively

IV LI

2% Lidocaine 1-2 ml subcutaneously infiltrate to blind the patients and outcome assessor

IV LI

infusion of normal saline at a same rate as IV LI (0.075ml/kg in 10 mins then 0.075ml/kg/h)
