Unlocking the Potential of Ketamine: A Systematic Review and Meta-analysis of its Safety and Efficacy in Acute Pain Management.

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
introductionEffective acute pain management in emergency departments (ED) remains a clinical priority. Ketamine, with its analgesic properties, is being evaluated as a potential alternative to opioids due to its rapid onset and distinct mechanism of action.
objectiveThis meta-analysis assessed the efficacy and safety of ketamine in adult ED patients with acute pain, compared to morphine, other opioids, or placebo.
methodsOnly randomized controlled trials (RCTs) comparing ketamine with opioids or placebo were included. The primary outcome was pain reduction measured using the numeric rating scale (NRS), and adverse events were evaluated as a safety endpoint. Data were analyzed using the Review Manager software. Pain scores at 10, 15, 30, and 60 minutes post-administration were compared between ketamine and control groups.
resultsNo significant differences in NRS pain scores were observed at 10 minutes [-0.46 (95% CI: -2.03, 1.10)], 30 minutes [-0.13 (95% CI: -0.62, 0.37)], or 60 minutes [-0.18 (95% CI: -0.97, 0.61)]. However, a statistically significant pain reduction was seen at 15 minutes in the ketamine group [-4.11 (95% CI: -7.91, -0.31)]. Adverse events showed no significant difference between groups [Risk Ratio: 1.20 (95% CI: 0.93, 1.55)]. High heterogeneity was noted (I² statistics). DISCUSSION: While ketamine may offer rapid analgesia at 15 minutes, its effects at other time points are comparable to controls. Safety profiles between groups were similar.
conclusionKetamine appears to be a safe alternative for acute pain relief in ED settings, with more RCTs needed to confirm time-specific efficacy.
