Comparison of Erector Spinae Plane Block vs Intravenous Lidocaine for Chronic Pain Post Mastectomy.

Comparison of Erector Spinae Plane Block and Intravenous Lidocaine for Chronic Pain Post Mastectomy: a Randomized Controlled Trial

Patients undergoing breast surgery were divided into two groups: Intravenous Lidocaine (Lido-IV) vs Erector Spinae Block (ESP).

For Lido-IV group, patients received a loading dose of Lidocaine than a continuous infusion till the end of surgery.

For ESP group, an ultrasound guided ESP Block was perormed before anesthetic induction.

Persistant pain post mastectomy was assessed by SFM-PQ score at 1, 3 and 6 months post surgery.

Patients undergoing breast surgery with lymph node dissection were divided into two groups: Intravenous Lidocaine (Lido-IV) vs Erector Spinae Block (ESP).

For Lido-IV group, patients received a loading dose of 1.5 mg/kg of Lidocaine than a continuous infusion of 2 mg/kg/h till the end of surgery.

For ESP group, an ultrasound guided ESP Block was perormed before anesthetic induction with injection of 30 ml of Ropivacaine 3.75%.

For both group, persistant pain post mastectomy was assessed by Item 5 of BPI score at 1, 3 and 6 months post surgery.
