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

introductionPostoperative pain management is a significant concern in surgery. This study aimed to compare the effects of two drug combinations, ropivacaine-dexmedetomidine and ropivacaine-ketamine, administered subcutaneously for postoperative pain control in patients undergoing inguinal hernia repair. MATERIALS AND

methodsIn this double-blind clinical trial, 140 patients scheduled for inguinal hernia surgery using the Lichtenstein technique at Valiasr Hospital in Arak were enrolled. They were randomly allocated into two treatment groups: dexmedetomidine + ropivacaine and ketamine + ropivacaine. The first group received dexmedetomidine 1 µg/kg plus ropivacaine 0.75% (3 mg/kg) diluted to a total volume of 10 mL with distilled water. The second group received ketamine 100 mg plus ropivacaine 0.75% (3 mg/kg) diluted to a total volume of 10 mL with distilled water. In both groups, subcutaneous injections were administered at the surgical incision site, which was then marked. Pain was assessed using the Visual Analog Scale (VAS) in the recovery room and at 2, 4, 6, 12, and 24 h postoperatively by a specialized surgical assistant. Changes in heart rate, mean arterial pressure, duration of analgesia, total opioid consumption, and complications were also recorded. Data were analyzed using SPSS version 20.

resultsThe mean pain score was significantly lower in the dexmedetomidine + ropivacaine group compared to the ketamine + ropivacaine group (P < 0.001). The mean duration of analgesia was significantly shorter in the ketamine + ropivacaine group (P = 0.001). The mean opioid consumption was significantly higher in the ketamine + ropivacaine group (P = 0.01).

conclusionDexmedetomidine, compared to ketamine, provides superior pain reduction, prolongs analgesia duration, and decreases opioid requirements following inguinal hernia repair using the Lichtenstein technique.
