NCT05008614

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Maximum postoperative pain score at rest on postoperative day 1

    pain score measured by the 11-pointed numeric rating scale (0: none/10: worst pain)

    Maximum pain score among the 9 am and 4 pm measurements on postoperative day 1

Secondary Outcomes (7)

  • Postoperative pain score at rest

    9am/4pm on postoperative day 1, 9am/4pm on postoperative day 2, 9am/4pm on postoperative day 3

  • Postoperative pain score at movement

    9am/4pm on postoperative day 1, 9am/4pm on postoperative day 2, 9am/4pm on postoperative day 3

  • Change in the total consumption (ml) of patient-controlled analgesia

    9am/4pm on postoperative day 1, 9am/4pm on postoperative day 2, 9am/4pm on postoperative day 3

  • Change in the quality of recovery-15 scale from baseline to postoperative day 3

    Day before surgery and 4pm on postoperative day 3

  • Postoperative pulmonary function test

    3 months after surgery

  • +2 more secondary outcomes

Study Arms (2)

Erector spinae plane block group (ESP group)

EXPERIMENTAL

Patients receiving continuous unilateral ESP block. Interventions: Procedure: Ultrasound-guided unilateral ESP block via catheter placement for continuous infusion Drug: Ropivacaine 0.75% Injectable Solution Device: 21-gauge 85 mm perineural catheter, 18-gauge 100 mm stimulator needle (Silverstim, Vygon, Ecouen, France)

Procedure: Erector spinae plane block group

Thoracic epidural analgesia group (TEA group)

ACTIVE COMPARATOR

Patients receiving thoracic epidural analgesia. Interventions: Procedure: Fluoroscopy-guided thoracic epidural analgesia Drug: Ropivacaine 0.75% Injectable Solution Device: 17-gauge Tuohy needle (FlexTip Plus®, Teleflex Medical, USA)

Procedure: Thoracic epidural analgesia group

Interventions

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)

Also known as: ESP group
