Erector Spinae Plane Block Versus Perioperative Intravenous Lidocaine for Thoracotomy

Erector Spinae Plane Block Versus Perioperative Intravenous Lidocaine for Postoperative Pain Control in Patients Undergoing Thoracotomy: A Prospective, Randomized, Double-blind Controlled Clinical Trial

Thoracotomy surgery is the most painful of all surgical procedures. Inadequate postoperative pain control in these patients may cause serious morbidity related to pulmonary, cardiovascular and emotional systems. Erector Spinae Plane Block (ESPB) was first described in 2016 and, it is frequently used for postoperative analgesia in thoracic surgery. Intravenous lidocaine exhibit analgesic activity through both the peripheral and central nervous system. Intravenous lidocaine has been shown to reduce postoperative pain intensity and accelerate postoperative recovery in many surgeries.

The investigators aimed to compare the effect of lidocaine infusion and erector spinae plane block on postoperative opioid consumption and pain scores.
