Brief Summary

The erector spinae plane block (ESPB) is gaining popularity as a regional anesthetic technique for major breast cancer surgery. Although there is controversy about its mechanism of action, emerging evidence suggests that clinical analgesia observed after ESPB in breast surgery may be due to rapid and sustained local anesthetic absorption from the injection site. Hence intravenous LA infusion (IVLI) during the perioperative period could offer an effective alternative to invasive ESPB.

Study Arms (2)

Group ESPB

ACTIVE COMPARATOR

For USG ESPB, 25 ml of 0.5% ropivacaine with 1:200,000 adrenaline will be drawn in a 25 ml syringe with a sterile label (available in a sterile package) displaying 'study drug for ESPB'. For IV infusion, 30 ml 0.9% saline will be drawn in a 50 ml syringe with a sterile label displaying 'study drug for IVI'. Both these syringes will be stored under strict aseptic precautions in a sterile tray until administration.

Drug: USG ESPB

Group IVLI

EXPERIMENTAL

For USG ESPB, 25 ml of 0.9% saline will be drawn in a 25 ml syringe with a sterile label (available in a sterile package) displaying 'study drug for ESPB'. For IV infusion, 30 ml 2% lidocaine will be drawn in a 50 ml syringe with a sterile label displaying 'study drug for IVI'. Both these syringes will be stored under strict aseptic precautions in a sterile tray until administration. The 30 ml volume for 2% lidocaine is decided as it can cover for a 70kg patient for a 3-hour surgical period.

Drug: Intravenous Infusion

Interventions

After obtaining the appropriate sonographic window, under strict aseptic precautions, the block needle is inserted in the plane of the US beam in a caudad to cranial direction until the tip is in contact with the transverse process (TP) at its lateral aspect. A test bolus of 0.9% saline (1-2 ml) is injected and sonographic evidence of erector spinae muscle displacement (posterior) from the underlying TP is sought to ensure that the tip of the block needle is indeed at the erector spinae muscle plane. The study drug from the 25 ml syringe with the label 'study drug for ESPB' (containing either 25 ml of 0.5% ropivacaine with 1:200,000 adrenaline or 0.9% saline depending on the group allocation) is injected in small aliquots over a minute. The anaesthesiologist performing the block and the patient is blinded to the group allocation. Successful injection reveals a clearly delineated posterior displacement of the erector spinae muscle.

Group ESPB

Following ultrasound-guided erector spinae plane block (USG ESPB), patients will be transferred to the operating room. General anesthesia (GA) will be administered according to a standardized protocol. Study Drug Infusion: Immediately after securing the airway, an intravenous infusion from a 50 ml syringe labeled "study drug for IVI" will commence. The study drug contains either 30 ml of 2% lidocaine or 0.9% saline, depending on group allocation. The infusion begins with a bolus rate of 0.1 ml/kg over 10 minutes and continues at 0.1 ml/kg/hr until surgical wound closure.
