Hidden Harlequin syndrome in neonatal and pediatric VA-ECMO
2022年5月20日 · The Harlequin Syndrome during VA-ECMO in neonates and children with severe acute respiratory distress syndrome. In severe (A) to moderate (B) LV dysfunction, the “mixing” point is in the middle of ascending aorta. In these two situations, the Harlequin syndrome is invisible: the four limbs are fully oxygenated but the coronary arteries are not.
To identify Harlequin syndrome in patients with venoarterial ...
2024年1月8日 · When Harlequin syndrome occurs, the heart and brain are directly damaged. Therefore, early identification and detection of Harlequin syndrome is the focus of the whole treatment. The right radial artery is a branch of the brachiocephalic trunk, so the blood oxygen content of the radial artery is often monitored to monitor the occurrence of ...
Harlequin syndrome is a serious complication in peripheral VAECMO that occurs when left ventricular function begins to recover while oxygenation of the lungs is poor [1]. e incidence has not been clearly stated, but it has been reported to be 8.8% [2]. When Harlequin syn-drome occurs, the heart and brain are directly damaged.
Risk of harlequin syndrome during bi-femoral peripheral VA …
2020年7月20日 · Risk of harlequin syndrome during bi-femoral peripheral VA-ECMO: should we pay more attention to the watershed or try to change the venous cannulation site?—authors’ reply. Buchtele N, Staudinger T, Schörgenhofer C, Schwameis M. We want to thank Honoré et al. for their important comments concerning our recently published article . The ...
Pulmonary complications associated with veno-arterial extra …
2020年5月11日 · The Harlequin syndrome may be treated by increasing VA-ECMO flow or adding a venous injection cannula either as a hybrid ECMO (veno-veno-arterial ECMO, Fig. 3) or as pure veno-venous ECMO if the function of the heart allows withdrawal of the arterial cannula.
The Harlequin syndrome is not present, coronary arteries are well oxygenated. D. In the subnormal LV recovery, the “mixing” point is close to the beginning of the brachio‑cephalic trunk. The blood ows coming from VA‑ECMO and LV are mixed: the saturation is decreased in the descending aorta and allows to detect easier Harlequin syndrome.
Optimizing PO2 during peripheral veno-arterial ECMO: a narrative …
2022年7月26日 · In an experimental study on 15 patients supported by VA-ECMO but without Harlequin syndrome, shifting the drainage cannula tip from IVC to SVC increased right radial P a O 2 from 127 to 153 mmHg . Then, clinical impact of this moderate oxygenation improvement in case of fulminant differential hypoxemia remains to be determined.
Neurological monitoring and management for adult …
2024年9月6日 · In VA ECMO, when the heart recovers before lung recovery, cerebral hypoxemia (especially of the right side of the brain) may occur due to the “differential oxygenation” (also called “Harlequin Syndrome” or “North–South Syndrome”), which is monitored by arterial blood gases from right radial arterial line, especially for those ...
Position of draining venous cannula in extracorporeal membrane ...
2018年6月15日 · If the venous blood is drained from the IVC (i.e., via a femoral cannula) the patient is at risk of developing a dual circulation (Harlequin syndrome, North-South syndrome, differential oxygenation) meaning that the highly oxygenated blood from the ECMO machine enters the descending aorta, supporting the lower body (splanchnic circulation ...
Impact of hyperoxia on the gut during critical illnesses
2024年3月1日 · Further animal model and clinical studies are needed to assess the frequency, severity, and risk factors for this condition. Most recent studies have detected arterial hyperoxia by measuring ABGs in samples extracted from the right arm as per the institutional ECMO protocol, primarily due to concerns regarding Harlequin syndrome [25, 101, 102].
