The effect of preoperative intravenous lidocaine on postoperative pain following hysteroscopy: A randomized controlled trial.
Trial report in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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 use of hysteroscopy for the diagnosis and treatment of uterine and endometrial abnormalities is often associated with postoperative pain. This randomized controlled trial aimed to assess the efficacy of preoperative intravenous (IV) lidocaine in reducing pain after hysteroscopy.
methodsIn total, 138 patients undergoing elective hysteroscopy at the CHA Bundang Medical Center, Seongnam, Korea were randomly assigned to a control group (n = 69) or a lidocaine group (n = 69), which received normal saline or IV lidocaine at 1.5 mg/kg, respectively. The primary outcome was the incidence of postoperative pain.
resultsThe incidence of pain was significantly lower in the IV lidocaine group than in the control group at the post-anesthesia care unit (27.3% vs 68.2%, P < .001). The visual analog scale (0-10) score (median [interquartile range]) was lower in the IV lidocaine group than in the control group (0 [0-2]) vs 2 [0-4]), P < .001). The use of rescue analgesics and postoperative nausea and vomiting were similar between the 2 groups. This study demonstrated that administering 1.5 mg/kg of preoperative IV lidocaine can be a simple method to reduce incidence of pain after hysteroscopy.
conclusionPreoperative bolus administration of 1.5 mg/kg of IV lidocaine may be used to decrease incidence of pain after hysteroscopy under general anesthesia.
