Intraarterial blood pressure monitoring in prehospital emergency care: a scoping review.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 2025. 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
backgroundBlood pressure is a key vital sign in prehospital emergency care and essential for assessing the hemodynamic status and guiding treatment. In the prehospital setting, blood pressure is usually measured intermittently with non-invasive cuff-techniques. However, intraarterial blood pressure monitoring with an arterial catheter offers continuous and more accurate measurements. This scoping review aimed to synthesize and analyze the current literature on intraarterial blood pressure monitoring in prehospital emergency care.
methodsPubMed, EMBASE, MEDLINE, Cochrane Central, and CINAHL were searched on April 15, 2025, following PRISMA-ScR guidelines and Joanna Briggs Institute methodology. Studies involving adults (≥ 18 years) having prehospital intraarterial blood pressure monitoring were included.
results1456 studies were screened and 24 studies finally included. The most frequent indications for intraarterial blood pressure monitoring were cardiopulmonary resuscitation and post resuscitation care. Arterial cannulation was performed by physicians in 92% of the cases. The radial artery was the most frequently used cannulation site. Arterial cannulation was successful in 82% of the patients. Major complications were very rare, with brachial artery cannulation bearing the highest risk for complications. Low agreement between intraarterial and non-invasive blood pressure measurements was reported. Actions based on intraarterial blood pressure monitoring were performed in 53% of the patients. Arterial cannulation was performed during different timepoints and had varying effects on prehospital time.
conclusionsIntraarterial blood pressure monitoring has been studied across a wide range of indications in prehospital emergency care with an acceptable cannulation success rate and low risk of complications. However, the included studies were mostly observational, necessitating randomized controlled trials analyzing patient-centered outcomes in defined populations.
