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

objectivesSubanaesthetic doses of esketamine may attenuate the opioid-induced cough reflex and prevent intraoperative haemodynamic fluctuations. This study aims to evaluate the effect of subanaesthetic doses of esketamine on the quality of recovery in patients who underwent abdominal surgery.

designRetrospective cohort study using propensity score matching (PSM) methodology.

settingA tertiary academic hospital.

participantsPatients who underwent abdominal surgery under general anaesthesia with tracheal intubation between 20 December 2022 and 30 April 2023, were retrospectively reviewed. Patients were assigned to the esketamine or control group based on whether they received a subanaesthetic dose of esketamine. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was extubation time (T1). Secondary outcomes included post-anaesthesia care unit (PACU) observation time (T2), total PACU time (T3), postoperative pain at multiple time points and adverse events including respiratory depression, hypertension and others.

resultsA total of 2177 patients underwent abdominal surgery. After PSM, 1196 patients were analysed, 598 in each group. Esketamine significantly reduced the extubation time compared with the control group (20.00 vs 23.00 min, p=0.001). Total PACU time was shorter in the esketamine group than in the control group (62 vs 66 min, p=0.015), although PACU observation time did not show a significant difference. Compared with the control group, the esketamine group had a lower incidence of severe postoperative pain immediately after extubation (0.33% vs 2.01%, p=0.007) and respiratory depression (2.68% vs 5.35%, p=0.027), but a higher incidence of hypertension (9.53% vs 6.35%, p=0.042). There were no other significant differences in adverse events between the two groups.

conclusionsThe use of subanaesthetic doses of esketamine for induction of anaesthesia in patients undergoing abdominal surgery may shorten the extubation time and reduce the incidence of postoperative complications. TRIAL REGISTRATION NUMBER: ChiCTR2300072154.
