Safety of peripheral intravenous administration of hypertonic saline: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2025. 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
Background: Hypertonic saline solution is critical for managing symptomatic hyponatremia and increased intracranial pressure (IICP). Though administered via central venous catheters (CVCs) traditionally, peripheral administration is a viable alternative, reducing delays and CVC-associated risks. This review evaluates the safety of peripheral hypertonic saline, focusing on infusion-related adverse events. Methods: A systematic search of MEDLINE, Embase, and Cochrane Library (up to December 2024) identified studies on peripheral hypertonic saline in adults. Studies reporting phlebitis, infiltration, extravasation, and thrombosis were included. Two reviewers independently screened studies and extracted data. Quality was assessed using the Newcastle-Ottawa Scale and Risk of Bias 2 tool. The review is registered on PROSPERO (CRD42024612330). Results: Thirteen studies involving 2,354 patients were included, comprising one randomized controlled trial and 12 cohort studies. Quality assessment showed a low risk of bias across all included studies. The pooled incidence of phlebitis was 2.3% (95% CI: 1.2%-4.1%), while infiltration and extravasation occurred at a rate of 2.1% (95% CI: 1.1%-3.9%). Thrombosis was rare, with an incidence of 0.8% (95% CI: 0.3%-1.7%). Most complications were mild and resolved conservatively. Conclusion: Peripheral hypertonic saline is a safe alternative to CVC placement, particularly in urgent situations where rapid intervention is required. Low complication rates support its broader use in clinical practice, enabling timely treatment while minimizing the risks associated with central access. These findings support consideration for updates to clinical guidelines, advocating for peripheral hypertonic saline as a first-line option in appropriate scenarios to enhance patient outcomes and streamline care delivery.
