AbstractWe aimed to evaluate associated factors for point-of-care ultrasound (POCUS)-guided percutaneous catheterization for venoarterial extracorporeal membrane oxygenation (VA-ECMO). VA-ECMO cases from March 2018 to October 2020 in Department of Intensive Care Unit, Binhaiwan Central Hospital of Dongguan, were enrolled. Clinical data, outcomes, and complications were recorded and summarized. Fifty-nine cases were enrolled, among which 88.1% succeeded in POCUS-guided catheterization via Seldinger technique, whereas 59.3% succeeded at the first puncture. Results showed that artery diameter and times of arterial punctures were independent associated factors for Seldinger puncture (P = .018, odds ratio [OR] = 23.374, 95% confidence interval [CI] = 1.706-320.270; P = .031, OR = 145.098, 95% CI = 1.592-13220.980), and artery diameter and cardiac ejection fraction value (≥30%/<30%) were independent associated factors for first puncture (P = .044, OR = 1.622, 95% CI = 1.014-2.596; P = .013, OR = 5.565, 95% CI = 1.441-21.488). For extracorporeal cardiopulmonary resuscitation patients, artery diameter was independent associated factor for Seldinger puncture (P = .022, OR = 2.070, 95% CI = 1.110-3.858), and cardiac ejection fraction value (≥30%/<30%) was independent associated factor for first puncture (P = .007, OR = 9.533, 95% CI = 1.847-49.204). Thirteen patients (22.0%) had local hemorrhage post puncture, 8 patients (13.6%) presented distal limb arterial ischemia, and 8 patients (13.6%) suffered puncture-related thrombosis. Vasoactive Inotropic Score was found to be independent associated factor for local hemorrhage (P = .039, OR = 0.994, 95% CI = 0.988-1.000), and the Acute Physiology and Chronic Health Evaluation II score was independent associated factor for thrombosis (P = .025, OR = 0.935, 95% CI = 0.882-0.992). Diabetes and cardiopulmonary resuscitation time before catheterization were independent factors for distal limb ischemia (P = .026, OR = 220.774, 95% CI = 1.905-25591.327; P = .017, OR = 1.054, 95% CI = 1.009-1.101). POCUS-guided percutaneous catheterization via Seldinger technique can be the first choice for VA-ECMO cannulation, especially for a team without angiotomy qualifications. Before cannulation, evaluating the target artery and heart function by ultrasound can help predict outcome of catheterization. Assessing risk factors (diabetes, cardiopulmonary resuscitation time before catheterization, Vasoactive Inotropic Score, the Acute Physiology and Chronic Health Evaluation II score) is helpful for prevention and treatment of complications.Copyright © 2022 the Author(s).
