Ultrasound-guided ESP Block vs. Wound Infiltration in Lumbar Surgery: A Comparative Analysis (ESP:Erector Spinae Plane)

Not Applicable

Completed

• Conditions: Lumbar Spinal Stenosis; Lumbar Spine Instability; Lumbar Spine Degeneration

• Registration Number: NCT06567964
• Lead Sponsor: Saglik Bilimleri Universitesi

Brief Summary

This study aimed to compare the efficacy of ultrasound-guided erector spinae plane block (ESPB) with that of wound infiltration (WI) for postoperative analgesia in lumbar spinal surgeries involving instrumentation.

Detailed Description

In this randomized controlled trial, 80 patients were divided into two groups: ESPB (n=40) and WI (n=40). Postoperative pain intensity was assessed using the Visual Analog Scale (VAS) at multiple time points within 24 hours. Additionally, opioid consumption, time to first rescue analgesia, incidence of postoperative nausea and vomiting (PONV), and patient satisfaction were evaluated.

Primary Outcome Measures

Name	Time	Method
Postoperative pain intensity	1., 6., 12., 24., and 48. hours postoperatively	The pain intensity was assessed via the visual analog scale (VAS).The VAS is a 10 cm scale ranging from 0 (no pain) to 10 (worst imaginable pain).

Secondary Outcome Measures

Name	Time	Method
Time to first request for rescue analgesia	Noted in hours in the first 48 hours postoperatively	Noted in hours postoperatively
Total Opioid Consumption	In the first 48 hours postoperatively	Recorded as morphine equivalents
Incidence of Side Effects	Recorded as binary outcomes (present/absent) in the first 48 hours postoperatively	Including nausea, vomiting, pruritus, and urinary retention,
Patient Satisfaction with Pain Management	At 48 hours postoperatively	Patient satisfaction was assessed via a 5-point Likert scale (1 = very dissatisfied, 5 = very satisfied)
