摘要

Background

Blood 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.

Methods

PubMed, 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.

Results

1456 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.

Conclusions

Intraarterial 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.
