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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeThe peripheral nerve blocks (PNB) are an important part of the multimodal analgesia for reducing postoperative pain, opioids consumption and its side effects. A new PNB, Erector spinae plane block (ESPB), has been revealed postoperative analgesic effect in various surgical procedures such as breast, thoracic and abdominal surgery, with the limitation of the studies for spine surgery. We aimed to evaluate the analgesic effect of ultrasound-guided bilateral erector spinae plane block (ESPB) after open lumbar spinal surgery.

methodsA double-blind, randomized controlled trial was conducted. Sixty-two patients undergoing posterior lumbar spinal surgery were randomly allocated into two groups. The ESPB group (n = 31) received ultrasound (US)-guided bilateral ESPB using 20 ml of 0.375% bupivacaine with adrenaline 5 mcg/ml per side. The control group (n = 31) received no intervention. The same postoperative analgesia regimen was applied by oral acetaminophen 10-15 mg/kg every 6 h, naproxen 250 mg twice daily, and intravenous (IV) morphine via patient-controlled analgesia (PCA) device. The postoperative morphine consumption, numerical pain score (NRS) and the side effects were recorded.

resultsThe bilateral ESPB group reduced the 24 h-morphine consumption by 42.9% (P < 0.001), decreased overall pain score at rest by 1.4 points (P = 0.02), and decreased overall pain score on movement by 2.2 points (P < 0.001). No severe complications related to the block technique or morphine used occurred.

conclusionThe US-guided bilateral ESPB demonstrated the effectiveness for postoperative analgesia management after open lumbar spinal surgery regarding reduced opioid consumption and pain score without any serious complications.
