PG - 1568-1576 LID - 10.1177/02676591221115935 [doi] AB - BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) flows are titrated to achieve adequate perfusion while attempting to ideally maintain arterial pulse pressure (PP). We assessed risk in patients with low PP defined as <10 mmHg within the first 2 days of support. METHODS: Demographics, haemodynamics, echocardiographic and radiological findings were recorded retrospectively in cases conducted between 2014 and 2016. Outcomes were hospital mortality, requirement for renal replacement therapy (RRT) and severe pulmonary oedema (PO). RESULTS: Of 101 patients, 66.3% were male, mean age was 56 (range 18-71 years), mean duration of support was 6.3 days +/- 4.1 days, 37.6% died prior to hospital discharge, 39.6% needed RRT and 11.9% had severe PO. Areas under the receiver operating curves of PP at 48 h for hospital mortality, RRT and severe PO were (respectively): 0.69 (95% CI 0.58-0.80, p = .001), 0.64 (95% CI 0.50-0.77, p = .044), 0.69 (95% CI 0.55-0.82, p = .009). The odds ratio for mortality, RRT, severe PO for those with low PP were (respectively) 2.8 (95% CI 1.01-7.5, p = .04), 3.1 (95% CI 1.11-8.40, p = .026), 7.6 (95% CI 2.06-27.89, p = .001). Central venous pressure, mean arterial pressure were not predictive. CONCLUSION: PP during the first 2 days of support is predictive of clinically important outcomes in patients supported with VA-ECMO.
