Comparing intravenous lidocaine and pethidine for pain management in emergency department patients with femoral bone fracture: a randomized controlled trial.
Trial report in BMC anesthesiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIntravenous lidocaine has shown promise as an effective analgesic in various clinical settings, but its utility for pain management in emergency departments, especially for bone fractures, remains relatively understudied.
objectiveThis study compared intravenous lidocaine to pethidine for femoral bone fracture pain management.
methodsThis double-blind, randomized, controlled clinical trial was conducted in the emergency department of AJA University of Medical Sciences affiliated hospitals. Patients aged 18-70 years-old with femoral bone fracture and experiencing severe pain, defined as a numerical rating scale (NRS) of pain ≥ 7, were included in the study. One group received intravenous pethidine (25 mg), while the other group received intravenous lidocaine (3 mg/kg, not exceeding 200 mg), infused with 250 ml saline over 20 min. Pain levels were evaluated before treatment administration (0 min) and at 10, 20, 30, 40, 50, and 60 min after treatment administration using the NRS.
resultsSeventy-two patients were enrolled in the study. Demographic characteristics and pain scores were similar between the two groups. The mean pain scores upon arrival for the lidocaine and pethidine groups were 8.50 ± 1 and 8.0 ± 1, respectively; after one hour, they were 4.0 ± 1 and 4.0 ± 1, respectively. While there was a statistically significant reduction in pain in both groups after one hour, there were no clinically or statistically significant differences between the two groups (p = 0.262). Pethidine had a higher incidence of adverse events, though not statistically significant. Additionally, females required more rescue analgesics.
conclusionThe administration of intravenous lidocaine is beneficial for managing pain in femoral bone fractures, suggesting that lidocaine could be a potent alternative to opioids.
