Factors related to complications of the invasive blood pressure system among adult and elderly patients: a prospective study.
Willian Marques de Souza, Victor Hugo Baldan Cypriano, Rosângela Aparecida de Sousa and 3 others
PMID 39907389WHAT IT FOUND
Complications led to early removal of invasive arterial blood pressure lines in 40% of adult ICU patients.
Lower bag pressure was associated with early removal, while most patient and line factors were not. Nurses should monitor bag pressure and phlebitis.
Key findings
01Complications occurred in 40% of monitored invasive blood pressure systems, and phlebitis was the most common complication.
02Lower pressure in the pressurizing bag was associated with removal before the scheduled time.
03No significant association was found with gender, age, dwell time, anticoagulants, antibiotics, sedation, eating habits, catheter gauge size, or other listed factors.

What it does not show
The study was done in one hospital and used convenience sampling, so the results may not apply to other ICUs or protocols. The text says 88 eligible participants were selected, but the tables analyse 50; the reason for the difference is not given in the supplied text. All lines were radial or dorsalis pedis, all used the same flexible needleless catheter, and no femoral punctures were installed, so other sites and materials could not be compared. The effect of vasoactive drugs could not be analysed reliably because very few patients were not using them. Because this was an observational study, the pressure-bag finding shows association, not cause.
The easy way to misread this
Do not read the bag-pressure finding as proof that changing the pressure prevents line loss. The study was observational and did not test an intervention; it only reported an association with early removal.
