Comparison between internal jugular vein access using midline catheter and peripheral intravenous access during cardiopulmonary resuscitation in adults

OBJECTIVES: Vascular access is an important procedure for drug administration during the resuscitation of a patient with cardiac arrest; however, it can be challenging under emergent conditions. This study aimed to investigate the efficiency of ultrasound-guided internal jugular venous access using a midline catheter versus peripheral intravenous access during cardiopulmonary resuscitation. METHODS: This was a prospective single-center observational study among patients who received cardiopulmonary resuscitation. The primary outcomes were the success rate of first attempt and the time taken for vascular access via the internal jugular and peripheral veins. We also measured the diameter of the internal jugular and peripheral veins at the access point and the distance from the access point to the heart. RESULTS: In all, 20 patients were included in the study. Internal jugular and peripheral venous access had a first-attempt success rate of 85% and 65%, respectively (p = 0.152). The time to access the internal jugular and peripheral veins was 46.4 ± 40.5 s and 28.8 ± 14.7 s, respectively (p = 0.081). The diameter of the internal jugular and peripheral veins was 10.8 ± 2.6 mm and 2.8 ± 0.8 mm, respectively (p < 0.001). The distance from the vascular access point to the heart was 20.3 ± 4.7 cm and 48.8 ± 13.1 cm for the internal jugular and peripheral veins, respectively (p < 0.001). CONCLUSIONS: There was a trend toward higher success rates in the internal jugular vein rather than the peripheral intravenous approach, which was not statistically significant.
