Factors related to complications of the invasive blood pressure system among adult and elderly patients: a prospective study.
Article in Revista latino-americana de enfermagem, 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
objectiveto identify the main factors related to complications of the invasive blood pressure system.
methodprospective study conducted with patients over 18 years of age admitted to intensive care, using a device for measuring invasive blood pressure. Participants were monitored during the catheter dwell-time and sociodemographic, clinical and device data were collected. The outcome analyzed was removal due to non-indication of use or due to complications. Student's t-test, Mann-Whitney U test, chi-square test and Fisher's exact test were used for the analyses.
results50 participants were included and monitored, and most devices were installed in the radial artery (86%), with a 20-gauge catheter (50%), all with a flexible catheter. Each patient remained, on average, 4.36 days (SD: 3.504) with the device. Regarding the outcomes, 60.0% of the devices were removed due to non-indication of use and 40.0% due to complications. Phlebitis was the most prevalent complication, and pressure in the bag was the factor associated with catheter removal before the time of indication (p=0.046).
conclusionthe main complications associated with this device were obstruction and phlebitis, while pressure in the bag was the factor related to catheter removal before indication.
background(1) Phlebitis was the most prevalent complication. (2) Pressure in the bag was associated with catheter removal before indication. (3) Length of stay and use of sedation were related to the onset of phlebitis.
