Abstract

Aim: To identify whether a novel pulse check technique, carotid artery compression using an ultrasound probe, can reduce pulse check times compared to manual palpation (MP).

Methods: This prospective study was conducted in an emergency department between February and December 2021. Point-of-care ultrasound–carotid artery compression (POCUS-CAC) was applied every 30 seconds, and carotid artery compressibility and pulsatility were assessed by probe compression. Another clinician performed MP of the femoral artery every 2 min. The primary outcome was the difference in the average time for pulse assessment between POCUS-CAC and MP. The secondary outcomes included the time difference in each pulse check between methods, the proportion of times greater than 5 s and 10 s, and the prediction of return of spontaneous circulation (ROSC) during ongoing chest compression.

Results: 25 cardiac arrest patients and 155 pulse checks were analyzed. The median (interquartile range) average time to carotid pulse identification per patient using POCUS-CAC was 1.62 (1.14–2.14) s compared to 3.50 (2.99–4.99) s with MP. In all 155 pulse checks, the POCUS-CAC time to determine ROSC was 0.44 times faster than the MP time (P < 0.001). The POCUS-CAC approach never exceeded 10 s, and the number of patients who required more than 5 s was significantly lower (5 vs . 37, P < 0.001). Under continuous chest compression, six pulse checks predicted the ROSC.

Conclusions: We found that emergency physicians could quickly determine pulses by applying simple POCUS compression of the carotid artery in cardiac arrest patients.
