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

backgroundThe aim of this prospective, randomized, controlled study was to evaluate the effect of ultrasound (US)-guided bilateral erector spinae plane (ESP) block on postoperative opioid consumption and respiratory recovery in patients with obesity undergoing laparoscopic sleeve gastrectomy (LSG).

methodsThe study was conducted on 40 patients scheduled for LSG. The patients were randomly allocated into either the ESP block group or the control group. The US-guided bilateral ESP block was performed preoperatively. The control group received no intervention.

resultsPostoperative median [IQR] tramadol consumption was significantly lower in the ESP block group [150.0 [100-200] mg vs 450.0 [400-500] mg, p < 0.0001]. Postoperative spirometric variables were significantly impaired in both groups, compared with preoperative variables (p < 0.0001). Intraoperative median [IQR] fentanyl consumption was 200.0 [200-200] µg in the ESP block group, and 350.0 [300-400] µg in the control group (p < 0.0001). Postoperative mean pain scores at rest and during movement were significantly lower in the ESP block group, at all time points (p < 0.05). In terms of mean arterial PH, Horowitz ratio, and PaCO

conclusionsUS-guided bilateral ESP block significantly reduced both intraoperative and postoperative analgesic consumptions and provided effective postoperative pain control for patients with obesity undergoing bariatric surgery. Following bariatric surgery, all patients' postoperative pulmonary functions deteriorated. The effect of US-guided bilateral ESP block on postoperative respiratory recovery could not be clearly demonstrated. Randomized controlled studies with a larger patient population are necessary.
