RESUMO
Extracorporeal membrane oxygenation (ECMO) is used in cases of severe respiratory failure refractory to medical management. Use of ECMO is increasing, along with new cannulation strategies including oxygenated right ventricular assist devices (oxy-RVADs). Multiple dual lumen cannulas are now available, which increase the potential for patient mobility and decrease the number of vascular access sites. However, dual lumen, single cannula flow can be limited by adequate inflow, requiring the need for an additional inflow cannula to meet patient demands. This cannula configuration may result in differential flows in the inflow and outflow limbs and altered flow dynamics, increasing the risk of intracannula thrombus. We describe a series of four patients treated with oxy-RVAD for COVID-19-associated respiratory failure complicated by dual lumen ProtekDuo intracannula thrombus.

OBJECTIVE: To assess societal preferences regarding allocation of extracorporeal membrane oxygenation (ECMO) as a rescue option for select patients with coronavirus disease 2019 (COVID-19). DESIGN: Cross-sectional survey of a nationally representative sample. SETTING: Amazon Mechanical Turk platform. PARTICIPANTS: In total, responses from 1,041 members of Amazon Mechanical Turk crowd-sourcing platform were included. Participants were 37.9 ± 12.6 years old, generally white (65%), and college-educated (66.1%). Many reported working in a healthcare setting (22.5%) and having a friend or family member who was admitted to the hospital (43.8%) or died from COVID-19 (29.9%). MEASUREMENTS AND MAIN RESULTS: Although most reported an unwillingness to stay on ECMO for >one week without signs of recovery, participants were highly supportive of ECMO utilization as a life-preserving technique on a policy level. The majority (96.7%) advocated for continued use of ECMO to treat COVID patients during periods of resource scarcity but would prioritize those with highest likelihood of recovery (50%) followed by those who were sickest regardless of survival chances (31.7%). Patients >40 years old were more likely to prefer distributing ECMO on a first-come first-served basis (21.5% v 13.3%, p < 0.05). CONCLUSION: Even though participants expressed hesitation regarding ECMO in personal circumstances, they were uniformly in support of using ECMO to treat COVID patients at a policy level for others who might need it, even in the setting of severe scarcity.

Patients undergoing cardiothoracic surgery are exposed to opioids in the operating room and intensive care unit and after hospital discharge. Opportunities exist to reduce perioperative opioid use at all stages of care and include alternative oral and intravenous medications, novel intraoperative regional anesthetic techniques, and postoperative opioid-sparing sedative and analgesic strategies. In this review, currently used and investigational strategies to reduce the opioid burden for cardiothoracic surgical patients are explored.

OBJECTIVE: Anticoagulation may be a challenge in coronavirus disease 2019 (COVID-19) extracorporeal membrane oxygenation due to endothelial injury and dysregulation of coagulation, which may increase the risk of thrombotic and bleeding complications. This report was created to describe the authors' single institutional experience, with emphasis on the high rate of intracranial hemorrhage for the first 10 patients with COVID-19 placed on venovenous extracorporeal membrane oxygenation (VV ECMO). DESIGN: Case series, retrospective analysis. SETTING: Single institution. PARTICIPANTS: Ten patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient characteristics, mortality, stroke rate, and length of stay data were collected in all patients. In addition, laboratory values of D-dimer and C-reactive protein and standard measurements of prothrombin and activated partial thromboplastin time were collected on all patients. Ten patients, each confirmed with COVID-19 via reverse transcription-polymerase chain reaction, were supported on VV ECMO for acute respiratory distress syndrome (ARDS) for a mean duration of 9.4 ± 7 days. Four of 10 patients had hemorrhagic strokes, 3 of which resulted in death. At 30 days after initiation of VV ECMO, a total of 7 survivors included 6 patients discharged from the hospital and 1 patient who remained in the intensive care unit. CONCLUSIONS: In this small study of 10 patients, intracranial hemorrhage was a common complication, resulting in a high rate of death. The authors urge caution in the anticoagulation management of VV ECMO for patients with severe ARDS and COVID-19 patients. Close monitoring of all hematologic parameters is recommended during ECMO support while awaiting larger, multicenter studies to examine the best practice.

OBJECTIVE: To assess the effectiveness of standardizing operating room (OR) to intensive care unit (ICU) handoffs in a mixed surgical population. SUMMARY OF BACKGROUND DATA: Standardizing OR to ICU handoffs improves information transfer after cardiac surgery, but there is limited evidence in other surgical contexts. METHODS: This prospective interventional cohort study (NCT02267174) was conducted in 2 surgical ICUs in 2 affiliated hospitals. From 2014 to 2016, we developed, implemented, and assessed the effectiveness of a new standardized handoff protocol requiring bedside clinician communication using an information template. The primary study outcome was number of information omissions out of 13 possible topics, recorded by trained observers. Data were analyzed using descriptive statistics, bivariate analyses, and multivariable regression. RESULTS: We observed 165 patient transfers (68 pre-, 97 postintervention). Before standardization, observed handoffs had a mean 4.7â±â2.9 information omissions each. After standardization, information omissions decreased 21.3% to 3.7â±â1.9 (P = 0.023). In a pre-specified subanalysis, information omissions for new ICU patients decreased 36.2% from 4.7â±â3.1 to 3.0â±â1.6 (P = 0.008, interaction term P = 0.008). The decrement in information omissions was linearly associated with the number of protocol steps followed (P < 0.001). After controlling for patient stability, the intervention was still associated with reduced omissions. Handoff duration increased after standardization from 4.1â±â3.3 to 8.0â±â3.9âminutes (P < 0.001). ICU mortality and length of stay did not change postimplementation. CONCLUSION: Standardizing OR to ICU handoffs significantly improved information exchange in 2 mixed surgical ICUs, with a concomitant increase in handoff duration. Additional research is needed to identify barriers to and facilitators of handoff protocol adherence.
