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

backgroundThoracolumbar interfascial plane (TLIP) block was recently described as a regional anesthetic technique to achieve analgesia for lumbar spine surgery by blocking the dorsal rami of spinal nerves. The study aims to test the hypothesis that TLIP block can offer pain control and reduce the perioperative analgesic requirement in patients undergoing spinal surgery.

methodsThere were 60 patients scheduled for lumbar spine surgery who were randomly assigned into two equal groups, TLIP and control groups. Patients in the TLIP group received general anesthesia and TLIP block while patients in the control group received general anesthesia alone. The primary outcome was the analgesic consumption in the first postoperative 24 hours, while intraoperative additional analgesic needs, time to the first request of postoperative analgesia, and pain scores were the secondary outcomes.

resultsAt 24 hours postoperatively, morphine consumption was lower in the TLIP group (5.13±1.55) versus the control group (14.33±2.58) mg. The intraoperative fentanyl consumption was lower in the TLIP group (15±35.11 mcgs) versus the control group (105±62.08 mcgs). Postoperative first request for analgesia was delayed in the TLIP group (7.30±2.69 h) compared to the control group (0.92±1.23 h). Postoperative Pain scores at rest were 2.53 ± 0.97 and 3.43 ± 0.50 at 24 hours in the TLIP group and the control group, respectively. Postoperative Pain scores at passive flexion of spine were 2.73 ±0.87 and 3.93 ±0.78 at 24 hours in the TLIP group and the control group, respectively. Patients in the TLIP group had lower perioperative hemodynamic responses to surgical stimulation in comparison to the control group.

conclusionCombined TLIP block with general anesthesia in patients undergoing spinal surgery reduced both postoperative and intraoperative analgesic needs, reduced intra-operative hemodynamic response to surgery, and achieved good postoperative pain control.
