Extracorporeal Life Support and Temporary CentriMag Ventricular Assist Device to Salvage Cardiogenic-Shock Patients Suffering from Prolonged Cardiopulmonary Resuscitation. J Clin Med 2022; 11:jcm11133773. [PMID: 35807056 PMCID: PMC9267666 DOI: 10.3390/jcm11133773] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 06/08/2022] [Accepted: 06/20/2022] [Indexed: 11/16/2022] Open
Abstract
Background: The extracorporeal life support (ECLS) and temporary bilateral ventricular assist device (t-BiVAD) are commonly applied in patients with cardiogenic shock. Prolonged cardiopulmonary resuscitation (CPR) has poor prognosis. Herein, we report our findings on a combined ECLS and t-BiVAD approach to salvage cardiogenic-shock patients with CPR for more than one hour. Methods: Fifty-nine patients with prolonged CPR and rescued by ECLS and subsequent t-BiVAD were retrospectively collected between January 2015 and December 2019. Primary diagnoses included ischemic, dilated cardiomyopathy, acute myocardial infarction, post-cardiotomy syndrome, and fulminant myocarditis. The mean LVEF was 16.9% ± 6.56% before t-BiVAD. The median ECLS-to-VAD interval is 26 h. Results: A total of 26 patients (44%) survived to weaning, including 13 (22%) bridged to recovery, and 13 (22%) bridged to transplantation. Survivors to discharge demonstrated better systemic perfusion and hemodynamics than non-survivors. The CentriMag-related complications included bleeding (n = 22, 37.2%), thromboembolism (n = 5, 8.4%), and infection (n = 4, 6.7%). The risk factors of mortality included Glasgow Coma Scale (Motor + Eye) ≤ 5, and lactate ≥ 8 mmol/L at POD-1, persistent ventricular rhythm or asystole, and total bilirubin ≥ 6 mg/dL at POD-3. Mortality factors included septic shock (n = 11, 18.6%), central failure (n = 10, 16.9%), and multiple organ failure (n = 12, 20.3%). Conclusions: Combined ECLS and t-BiVAD could be a salvage treatment for patients with severe cardiogenic shock, especially for those already having prolonged CPR. This combination can correct organ malperfusion and allow sufficient time to bridge patients to recovery and heart transplantation, especially in Asia, where donation rates are low, as well as intracorporeal VAD or total artificial heart being seldom available.

Abstract
OBJECTIVES Intensive care audits point to family refusal as a major barrier to organ donation. In this study, we sought to understand refusal by accounting for the decision-maker's mindset. This focused on: (1) how decisions compare when made on behalf of a relative (vs the self); and (2) confidence in decisions made for family members. DESIGN Cross-sectional survey in Singapore. SETTING Participants were recruited from community settings via door-to-door sampling and community eateries. PARTICIPANTS 973 adults who qualified as organ donors in Singapore. RESULTS Although 68.1% of participants were willing to donate their own organs, only 51.8% were willing to donate a relative's organs. Using machine learning, we found that consistency was predicted by: (1) religion, and (2) fears about organ donation. Conversely, participants who were willing to donate their own organs but not their relative's were less driven by these factors, and may instead have resorted to heuristics in decision-making. Finally, we observed how individuals were overconfident in their decision-making abilities: although 78% had never discussed organ donation with their relatives, the large majority expressed high confidence that they would respect their relatives' wishes on death. CONCLUSIONS These findings underscore the distinct psychological processes involved when donation decisions are made for family members. Amidst a global shortage of organ donors, addressing the decision-maker's mindset (eg, overconfidence, the use of heuristics) may be key to actualizing potential donors identified in intensive care units.

Transplant Proc 2021; 53:2095-2104.

Abstract
Lack of knowledge adversely affects one's attitude toward organ donation. To increase understanding, Singapore informs each citizen and permanent resident turning 21 years old through information mailers sent to their place of residence. This study measured the current knowledge on organ donation of 106 polytechnic students (aged 16-24 years) and their reception toward 3 versions of the information mailers (current, revised version 1, and version 2). It was found that 69% of respondents were unaware of the Human Organ Transplant Act. The current mailer also lacks appeal, with only 3.8% of respondents preferring the current version, compared with 42% to 44% who preferred revised version 1 and 52% to 55% who preferred revised version 2. Qualitative responses suggest that the assimilation of elements in both new versions (ie, visuals, layout, and font) will likely lead to better appeal. Findings therefore reinforced the need for revision of current information mailers to captivate young adults to find out about organ donation in Singapore and make informed end-of-life decisions. Further research should consider eliciting more detailed qualitative responses in a conducive setting under a wider time frame.

Abstract
BACKGROUND It is poorly understood how public perception of the difference between brain death and circulatory death may influence attitudes towards organ donation. We investigated the public opinion on brain death versus circulatory death and documented inconsistencies in the legislations of countries with different cultural and socioeconomic backgrounds. METHODS Using a crowdsourcing approach, we randomized 1072 participants from 30 countries to a case report of organ donation after brain death or to one following circulatory death. Further, we sampled guidelines from 24 countries and 5 continents. RESULTS Of all participants, 73% stated they would be willing to donate all organs, while 16% would want to donate some of their organs. To increase the rate of donations, 47% would agree with organ donation without family consent as the default. Exposure to "brain death" was not associated with a lesser likelihood of participants agreeing with organ donation (82.1%) compared to "circulatory death" (81.9%; relative risk 1.02, 95% CI 0.99 to 1.03; p = .11). However, participants exposed to "circulatory death" were more certain that the patient was truly dead (87.9% ± 19.7%) than participants exposed to "brain death" (84.1% ± 22.7%; Cohen's d 0.18; p = 0:004). Sampling of guidelines revealed large differences between countries regarding procedures required to confirm brain death and circulatory death, respectively. CONCLUSIONS Implementation of organ donation after circulatory death is unlikely to negatively influence the willingness to donate organs, but legislation is still brain death-based in most countries. The time seems ripe to increase the rate of circulatory death-based organ donation.

Abstract
Background: The demand for transplantable organs has increased in Singapore. However, organ donation has been consistently lower than international standards. Donation after brain death (DBD) most commonly follows intracranial haemorrhage (ICH). Objective: Our aim was to identify missed opportunities for organ donation among those who presented to the Emergency Department (ED) and died following ICH. Methods: A retrospective study was carried out for all cases of ICH presenting to the ED from 1 January 2013 to 31 December 2017. The patients’ medical records were reviewed for identification of potential donors and actualisation of organ donation. Results: There were 615 cases of ICH, with a mortality rate of 6.0%. Among those who died, 28 (75.7%) died in the Intensive Care Unit (ICU) and nine (24.3%) patients had withdrawal of care in the ED. Thirty patients (81.1%) were potential donors but organ donation was actualised in only three (8.1%) patients. Thirteen organs, as well as heart valves and iliac vessels were retrieved from the organ donors for transplantation. Conclusion: There were missed opportunities for organ donation. EDs have an important role to play in the national organ donation programme by identifying potential donors for organ donation and considering admitting these patients to ICU to facilitate organ donation.
