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

backgroundNowadays, increasingly more preemptive analgesia studies focus on postoperative pain; however, the impact of preemptive analgesia on perioperative opioid requirement is not well defined. This study was carried out in order to evaluate whether preoperative intravenous flurbiprofen axetil can reduce perioperative opioid consumption and provide postoperative analgesia in patients undergoing thyroid gland surgery.

methodsNinety patients undergoing elective thyroid gland surgery were randomly assigned to three groups. Group A (Control) was administered Intralipid(®) 2 ml as a placebo 15 min before the cervical plexus block and at the end of the surgery; Group B (Routine analgesia) was administered a placebo 15 min before the cervical plexus block and flurbiprofen 50 mg at the end of the surgery; Group C (Preemptive analgesia) was administered intravenous flurbiprofen 50 mg 15 min before the cervical plexus block and a placebo at the end of the surgery. Sufentanil administration during the surgery and the 24 h satisfaction score on analgesic therapy were both recorded. The analgesic efficacy was assessed at 1, 2, 4, 6, 8, 12, and 24 hours after the surgery, based on visual analog scales.

resultsNinety patients were involved in the study. One patient from Group B did not have their scheduled surgery; eighty-nine patients completed the study. There were no significant differences in the patient demographics between the three groups. Visual analog scales: 1, 2, 4 h for Group A was significantly higher than Groups B and C (P<0.05); Sufentanil administration during surgery: Group C was obviously lower compared to Groups A and B (P<0.05); 24 h satisfaction score: Groups B and C were higher than Group A (P<0.05).

conclusionPreoperative administration of intravenous Flurbiprofen axetil reduced analgesic consumption during surgery, but not postoperative pain scores.
