Summary

This prospective, randomized, assessor-blinded study is designed to evaluate the postoperative analgesic efficacy of the ultrasound-guided continuous erector spinae plane (ESP) block in patients undergoing thoracotomy. We hypothesize that US-guided ESP block is not inferior to thoracic epidural analgesia in terms of postoperative pain control in these patients.

Detailed description

Adult patients undergoing elective unilateral thoracotomy for lung cancer resection are randomly allocated to receive US-guided ESP block (n=31) or thoracic epidural analgesia (n=31). Both procedures are performed prior to surgery. Each patient was assessed by a blinded investigator on postoperative day (POD) 1,2 and 3. The primary outcome is pain severity evaluated by a numeric rating scale (NRS) at POD1.

Interventions

Type	Name	Description
PROCEDURE	Erector spinae plane block group	Before surgery, an anesthesiologist will perform unilateral ESP block with catheterization under ultrasound guidance in the procedure room. Drug: Ropivacaine 0.75% Injectable Solution 0.2% ropivacaine is continuously infused to the erector spinae plane at T5 level via 18G 85 mm perineural catheter (Silverstim, Vygon, Ecouen, France) (basal infusion: 10ml/hr, bolus 5ml, lockout time: 20min)
PROCEDURE	Thoracic epidural analgesia group	Before surgery, an anesthesiologist will perform unilateral ESP block with catheterization under fluoroscopy guidance in the procedure room. Drug: Ropivacaine 0.75% Injectable Solution 0.2% ropivacaine is continuously infused to the erector spinae plane at T5 level via 17-gauge catheter (FlexTip Plus®, Teleflex Medical, USA) (Silverstim, Vygon, Ecouen, France) (basal infusion: 3ml/hr, bolus 1ml, lockout time: 20min)
