1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

purposeSpine surgeries have experienced exponential growth over the past 2 decades. These surgeries are often accompanied by long and severe perioperative pain, presenting a significant management challenge. This study aims to assess and compare the efficacy of two techniques for postoperative pain (POP) management in lumbar spine surgeries: ultrasound-guided erector spinae plane block (ESPB) and intraoperative freehand ESPB.

methodsIn this prospective randomized non-inferiority trial (Registration Number: IRCT20221107056427N1), adult patients who were candidates for lumbar spinal fusion surgery were randomly divided into two groups: ultrasound-guided ESPB (n = 29) and freehand ESPB (n = 29). The primary outcomes were the total amount of morphine consumed during the first 24 h following the surgery and the numerical rating scale (NRS) pain score at various time points within the first 24 h following the surgery. The secondary outcome was the fentanyl used during surgery.

resultsParticipants in the intraoperative freehand approach had considerably higher total morphine consumption in the first postoperative 24 h. The trend of NRS changes in both the ultrasound-guided ESPB group and the freehand ESPB group during the first 24 h after surgery showed a significant decrease. Still, there was no significant difference between the two groups. However, the first analgesic demand time was significantly shorter in the intraoperative freehand ESPB group compared to the ultrasound-guided approach.

conclusionAccording to our results, the ultrasound-guided approach of ESPB is more effective in POP management and opioid sparing in lumbar spinal fusion surgeries compared to the freehand approach. However, the data from this study are not sufficient to draw robust conclusions, and further randomized controlled trials with larger sample sizes are required to validate our results.
