Restrictive and liberal transfusion strategies in extracorporeal membrane oxygenation: A retrospective observational study.

Background: To compare the outcomes of patients requiring extracorporeal membrane oxygenation (ECMO) support who had a restrictive transfusion strategy with those who had a liberal strategy.

Study Design And Methods: We retrospectively reviewed all adult patients from 2010 to 2019 who received a minimum of one packed red blood cell (pRBC) during ECMO. Hemoglobin values before each transfusion were retrieved.

Effect of hospital case volume on clinical outcomes of patients requiring extracorporeal membrane oxygenation: a territory-wide longitudinal observational study.

Background: The utilization of extracorporeal membrane oxygenation (ECMO) has increased rapidly around the world. Being an overall low-volume high-cost form of therapy, the effectiveness of having care delivered in segregated units across a geographical locality is debatable.

Methods: All adult extracorporeal membrane oxygenation cases admitted to public hospitals in Hong Kong between 2010 and 2019 were included.

Comparing the outcomes of bedside percutaneous VA-ECMO decannulation by ProGlide and Manta in a high-ECMO-volume center in Hong Kong.

Background: The use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) decannulation with different percutaneous closure devices has been increasing. At our center, ProGlide devices have been used since November 2018, and Manta devices became an alternative since March 2020. This study aimed to compare the success and complication rates and the clinical outcomes of ProGlide and Manta devices for VA-ECMO decannulation after arteriotomy wound closure.

One-year experience of bedside percutaneous VA-ECMO decannulation in a high-ECMO-volume center in Hong Kong.

Background: When veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support can be terminated, open repair of arteriotomy wounds in operating theaters is the standard of practice. Comparable outcomes by percutaneous decannulation using different closure devices have been reported. However, transport of the critically- ill, man-power and timeslots of operating theaters could be saved if decannulation was performed at bedside.

Case report of successful peripheral veno-arterial extracorporeal membrane oxygenation in a patient with chronic type B aortic dissection.

A case report of successful application of peripheral veno-arterial extracorporeal membrane oxygenation in a patient with chronic type B aortic dissection and myocardial stunning to bridge to recovery was presented. Good outcomes from the application of peripheral veno-arterial extracorporeal membrane oxygenation in aortic dissection have rarely been reported, and the considerations of starting veno-arterial extracorporeal membrane oxygenation in this situation were seldom discussed. The orthodox that peripheral veno-arterial extracorporeal membrane oxygenation is an absolute contraindication for initiation of peripheral veno-arterial extracorporeal membrane oxygenation should be challenged.

Enhanced vascular assessment by ultrasound using microbubble contrast after percutaneous decannulation of peripheral veno-arterial extracorporeal membrane oxygenation.

Termination of peripheral veno-arterial extracorporeal membrane oxygenation support by managing the arteriotomy wound using a percutaneous closure device was reported successful and effective. However, careful assessment by clinical examination and also ultrasound Doppler assessment of the lower limb vasculature after closure is of paramount importance. Complications including pseudoaneurysm, arterial stenosis, and acute thrombosis are not uncommon.

Real-time ultrasound-guided bedside closure of arteriotomy wound using MANTA closure device during venoarterial extracorporeal membrane oxygenation decannulation.

Percutaneous closure of arteriotomy wound during peripheral venoarterial extracorporeal membrane oxygenation decannulation was shown to be safe and allow earlier mobilization. The new Manta vascular closure device (Essential Medical), designed for the closure of arterotomy wound created by large-bore vascular sheaths up to 25Fr during endovascular catheterization procedures, was reported to be applicable in venoarterial extracorporeal membrane oxygenation decannulation. In this article, we would like to share our experience of using real-time ultrasound guidance to ensure the safe application of Manta during bedside venoarterial extracorporeal membrane oxygenation decannulation.

Confirming Distal Perfusion Catheter Position by Micro-bubbles in Patients on Peripheral Venoarterial Extracorporeal Membrane Oxygenation.

Distal perfusion catheter (DPC) is commonly employed to prevent lower limb ischemia in patient put on peripheral venoarterial extracorporeal membrane oxygenation. Confirming its proper position is important but technically difficult by bedside ultrasound. We describe in this article a novel method to use micro-bubble ultrasound enhancing agents, which are commonly used for contrast echocardiography studies, to confirm DPC position at the bedside.

Experiences with Continuous Venovenous Hemofiltration using 18mmol/L predilution Citrate anticoagulation and a Phosphate Containing Replacement Solution.

Context: Regional citrate anticoagulation for continuous renal replacement therapy is associated with a longer filter-life, less bleeding events and improved mortality. Problems associated with using Prismocitrate 10/2 solution in continuous renal replacement therapy, include hypomagnesemia, hypophosphatemia and the need for additional bicarbonate infusion.

Aims: This study uses the new Prismocitrate 18/0 solution for improved buffer balance and Phoxilium solution for a more favourable electrolyte profile.
