Refractory end-stage pulmonary failure may benefit from extracorporeal life support (ECLS) as a bridge to lung transplantation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) has been recommended for patients who have failed conventional medical therapy and mechanical ventilation. Veno-arterial (VA) ECMO may be used in patients with acute right ventricular (RV) failure, haemodynamic instability, or refractory respiratory failure.

The ProtekDuo cannula represents an important advancement in medical devices for MCS in the setting of RVF. When combined with an extracorporeal blood pump, the dual-lumen design allows for direct bypass of the RV using simultaneous drainage and return of blood using percutaneous, single-site access.

Extracorporeal membrane oxygenation (ECMO) represents the mainstay of mechanical circulatory support for PCCS; however, its availability is limited to larger experienced centers, leading to a mismatch between centers performing cardiac surgery and hospitals offering ECMO management beyond cannulation. We sought to evaluate the outcomes and complications of PCCS patients requiring veno-arterial (V-A) ECMO cannulated at our hospital compared to those cannulated at referral hospitals.

Purpose: Most extracorporeal membrane oxygenation (ECMO) cannulations are performed by cardiothoracic surgeons (CTS). Due to an increase in utilization of ECMO and limited availability of CTS, there is a mismatch between ECMO demand and CTS accessibility for remote cannulations. We report our intensivist-led program's experience in remote ECMO cannulations, retrievals, complications, and outcomes.

The ProtekDuo was subsequently used as double-lumen drainage cannula, returning blood into a newly percutaneously placed femoral arterial cannula, mimicking venoarterial (V-A) ECMO in VP-A configuration. The following day, an Impella 5.

The objective of this study was to examine the association between prophylactic vasopressor administration and the incidence of peri-intubation hypotension and other clinical outcomes.
Design: A secondary analysis of two multicenter randomized clinical trials.
We sought to review the role of extracorporeal membrane oxygenation (ECMO) for the management of burn and smoke inhalation injury in the adult patient population. Therefore, we conducted a systematic search of the literature according to specific combination of key words to ascertain the effectiveness of this support strategy. A total of 26 articles were filtered out of 269 and considered suitable for this study.

More recent studies have defined successful placement of an ETT using a single laryngoscope insertion followed by a single ETT insertion. We sought to estimate the prevalence of first-attempt success using these 2 definitions and estimate their associations with the duration of intubation and serious complications.

Very few studies have given insight into the outcomes of pregnant and postpartum patients requiring ECMO support.
Methods: Single center, retrospective, observational study of female pregnant and postpartum patients suffering COVID-19 ARDS and requiring ECMO.
Study Objective: To compare the effect of the use of a video laryngoscope versus a direct laryngoscope on each step of emergency intubation: laryngoscopy (step 1) and intubation of the trachea (step 2).
Methods: In a secondary observational analysis of data from 2 multicenter, randomized trials that enrolled critically ill adults undergoing tracheal intubation but did not control for laryngoscope type (video laryngoscope vs direct laryngoscope), we fit mixed-effects logistic regression models examining the 1) the association between laryngoscope type (video laryngoscope vs direct laryngoscope) and the Cormack-Lehane grade of view and 2) the interaction between grade of view, laryngoscope type (video laryngoscope vs direct laryngoscope), and the incidence of successful intubation on the first attempt.
Results: We analyzed 1,786 patients: 467 (26.
High-risk/massive pulmonary embolism (PE) has a high mortality rate, especially when cardiac arrest occurs. Venoarterial (V-A) extracorporeal membrane oxygenation (ECMO) can rapidly restore and maintain circulation while a decision regarding further care or performance of other interventions takes place. Catheter-based embolectomy (CBE) is a technology that allows for percutaneous access, clot removal, and potential resolution of shock while avoiding sternotomy required for traditional pulmonary embolectomy.

Herein, we describe a case of a healthy young male who presented with ARDS refractory to mechanical ventilation and concomitant bilateral pulmonary emboli managed with extracorporeal membrane oxygenation (ECMO) and embolectomy. The embolectomy and initial veno-venous ECMO configuration failed to correct the patient's hypoxemia despite maximal flows.

Mechanical circulatory support (MCS) may be considered as an advanced treatment option. The ProtekDuo is a cannula that can be used to provide acute right ventricular support as part of a temporary percutaneous (tp) right ventricular assist device (RVAD) system.

Case Report: We describe remote cannulation and transport of two patients with ProtekDuo cannula. One patient had isolated acute right ventricular failure (aRVF), was cannulated with ProtekDuo cannula in venopulmonary (V-P) configuration and transported by ambulance.
Objective: Assessment of the results of the ProtekDuo cannula applied for dedicated right ventricular support with oxygenator in ARDS secondary to COVID-19.
Methods: Systematic literature search in NHS library, Medline (Pubmed) and EMBASE using appropriate keywords as well as PICOS and PRISMA approach.
Results: Out of 285 publications found, 5 publications met the search criteria and were included in this review.
Objective: The ProtekDuo with oxygenator mimics veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) in veno-pulmonary (V-P) configuration. We have recently developed a new configuration by utilizing a 25 Fr multistage femoral venous drainage cannula and by returning oxygenated blood through both lumina of the double lumen ProtekDuo cannula (V-VP configuration), thereby creating partial right ventricular bypass and oxygenated blood flow of up to seven LPM. We investigated our experience with V-P and V-VP ECMO in patients suffering from COVID-19 acute respiratory distress syndrome (ARDS).

Whether administering an intravenous fluid bolus to critically ill adults undergoing tracheal intubation prevents severe hypotension, cardiac arrest, or death remains uncertain.
Objective: To determine the effect of fluid bolus administration on the incidence of severe hypotension, cardiac arrest, and death.
The SARS-CoV-2 virus spreading across the world has led to surges of COVID-19 illness, hospitalizations, and death. The complex and multifaceted pathophysiology of life-threatening COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis warrants early interventions to address all components of the devastating illness. In countries where therapeutic nihilism is prevalent, patients endure escalating symptoms and without early treatment can succumb to delayed in-hospital care and death.

Whether administration of an intravenous fluid bolus prevents cardiovascular collapse during tracheal intubation remains uncertain. A prior randomised trial found fluid bolus administration to be ineffective overall but suggested potential benefit for patients receiving positive pressure ventilation during tracheal intubation.

Two principal proposals for diagnostic criteria have emerged. One, originally published in 2012, is labeled by its authors as a "consensus" (re-termed here as "consensus-1").
