Abstract
Mechanical circulatory support (MCS) as a bridge to lung transplant is an infrequent but accepted pathway in patients who have refractory end-stage pulmonary failure. The American Association of Thoracic Surgeons Expert Consensus Guidelines, published in 2023, recommends venovenous (VV) extracorporeal membrane oxygenation (ECMO) as the initial configuration for those patients who have failed conventional medical therapy, including mechanical ventilation, while waiting for lung transplantation and needing MCS. Alternatively, venoarterial (VA) ECMO can be used in patients with acute right ventricular failure, hemodynamic instability, or refractory respiratory failure. With the advancement in percutaneous venopulmonary (VP) ECMO cannulation techniques, this option is becoming an attractive configuration as bridge to lung transplantation. This configuration enhances stability of the right ventricle, prevents recirculation with direct introduction of pulmonary artery oxygenation, and promotes hemodynamic stability during mobility, rehabilitation, and sedation-weaning trials before lung transplantation. Here, we present a case series of eight percutaneous VP ECMO as bridge to lung transplant with all patients mobilized, awake, and successfully transplanted with survival to hospital discharge.

Abstract
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.

Abstract
COVID-19 infection can lead to severe acute respiratory distress syndrome (ARDS), right ventricular (RV) failure and pulmonary hypertension. Venovenous extracorporeal membrane oxygenation (V-V ECMO) has been used for patients with refractory hypoxemia. More recently dual-lumen right atrium to pulmonary artery oxygenated right ventricular assist devices (Oxy-RVAD) have been utilized in the severe medical refractory COVID ARDS setting. Historically, animal data has demonstrated that high continuous non-pulsatile RVAD flows, leading to unregulated and unprotected circulation through the pulmonary vessels is associated with an increased risk of pulmonary hemorrhage and increased amount of extravascular lung water. These risks are heightened in the setting of ARDS with fragile capillaries, left ventricular (LV) diastolic failure, COVID cardiomyopathy, and anticoagulation. Concurrently, due to infection, tachycardia, and refractory hypoxemia, high V-V ECMO flows to match high cardiac output are often necessary to maintain systemic oxygenation. Increase in cardiac output without a concurrent increase in VV ECMO flow will result in a higher fraction of deoxygenated blood returning to the right heart and therefore resulting in hypoxemia. Several groups have suggested using a RVAD only strategy in COVID ARDS; however, this exposes the patients to the risk of pulmonary hemorrhage. We present one of the first known cases using an RV mechanical support, partial flow pulmonary circulation, oxygenated Veno-venopulmonary (V-VP) strategy resulting in RV recovery, total renal recovery, awake rehabilitation, and recovery.

Abstract
BACKGROUND Recent studies have revealed high rates of burnout among respiratory therapists (RTs), which has implications for patient care and outcomes as well as for the health care workforce. We sought to better understand RT well-being during the COVID-19 pandemic. The purpose of this study was to determine rates and identify determinants of well-being, including burnout and professional fulfillment, among RTs in ICUs. METHODS We conducted a mixed-methods study comprised of a survey administered quarterly from July 2020-May 2021 to critical-care health care professionals and semi-structured interviews from April-May 2021 with 10 ICU RTs within a single health center. We performed multivariable analyses to compare RT well-being to other professional groups and to evaluate changes in well-being over time. We analyzed qualitative interview data using thematic analysis, followed by mapping themes to the Maslow needs hierarchy. RESULTS One hundred eight RTs responded to at least one quarterly survey. Eighty-two (75%) experienced burnout; 39 (36%) experienced professional fulfillment, and 62 (58%) reported symptoms of depression. Compared to clinicians of other professions in multivariable analyses, RTs were significantly more likely to experience burnout (odds ratio 2.32 [95% CI 1.41-3.81]) and depression (odds ratio 2.73 [95% CI 1.65-4.51]) and less likely to experience fulfillment (odds ratio 0.51 [95% CI 0.31-0.85]). We found that staffing challenges, safety concerns, workplace conflict, and lack of work-life balance led to burnout. Patient care, use of specialized skills, appreciation and a sense of community at work, and purpose fostered professional fulfillment. Themes identified were mapped to Maslow's hierarchy of needs; met needs led to professional fulfillment, and unmet needs led to burnout. CONCLUSIONS ICU RTs experienced burnout during the pandemic at rates higher than other professions. To address RT needs, institutions should design and implement strategies to reduce burnout across all levels.

Topical nitroglycerin to detect reversible microcirculatory dysfunction in patients with circulatory shock after cardiovascular surgery: an observational study. Sci Rep 2022; 12:15257. [PMID: 36088474 PMCID: PMC9464203 DOI: 10.1038/s41598-022-19741-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 09/02/2022] [Indexed: 11/09/2022] Open
Abstract
AbstractPersistent abnormalities in microcirculatory function are associated with poor clinical outcomes in patients with circulatory shock. We sought to identify patients with acutely reversible microcirculatory dysfunction using a low-dose topical nitroglycerin solution and handheld videomicroscopy during circulatory shock after cardiac surgery. Forty subjects were enrolled for the study, including 20 preoperative control and 20 post-operative patients with shock. To test whether microcirculatory dysfunction is acutely reversible during shock, the sublingual microcirculation was imaged with incident dark field microscopy before and after the application of 0.1 mL of a 1% nitroglycerin solution (1 mg/mL). Compared to the control group, patients with shock had a higher microcirculation heterogeneity index (MHI 0.33 vs. 0.12, p < 0.001) and a lower microvascular flow index (MFI 2.57 vs. 2.91, p < 0.001), total vessel density (TVD 22.47 vs. 25.90 mm/mm2, p = 0.005), proportion of perfused vessels (PPV 90.76 vs. 95.89%, p < 0.001) and perfused vessel density (PVD 20.44 vs. 24.81 mm/mm2, p < 0.001). After the nitroglycerin challenge, patients with shock had an increase in MFI (2.57 vs. 2.97, p < 0.001), TVD (22.47 vs. 27.51 mm/mm2, p < 0.009), PPV (90.76 vs. 95.91%, p < 0.001), PVD (20.44 vs. 26.41 mm/mm2, p < 0.001), venular RBC velocity (402.2 vs. 693.9 µm/s, p < 0.0004), and a decrease in MHI (0.33 vs. 0.04, p < 0.001. Thirteen of 20 patients showed a pharmacodynamic response, defined as an increase in PVD > 1.8 SD from shock baseline. Hemodynamics and vasoactive doses did not change during the 30-min study period. Our findings suggest a topical nitroglycerin challenge with handheld videomicroscopy can safely assess for localized recruitment of the microcirculatory blood flow in patients with circulatory shock and may be a useful test to identify nitroglycerin responsiveness.

How Should ECMO Be Used Under Conditions of Severe Scarcity? A Population Study of Public Perception. J Cardiothorac Vasc Anesth 2022; 36:1662-1669. [PMID: 34218997 PMCID: PMC8249692 DOI: 10.1053/j.jvca.2021.05.058] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/12/2021] [Accepted: 05/30/2021] [Indexed: 01/27/2023]
Abstract
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.

Abstract
INTRODUCTION Lactic acidosis after cardiac surgery with cardiopulmonary bypass is common and associated with an increase in postoperative morbidity and mortality. A number of potential causes for an elevated lactate after cardiopulmonary bypass include cellular hypoxia, impaired tissue perfusion, ischemic-reperfusion injury, aerobic glycolysis, catecholamine infusions, and systemic inflammatory response after exposure to the artificial cardiopulmonary bypass circuit. Our goal was to examine the relationship between early abnormalities in microcirculatory convective blood flow and diffusive capacity and lactate kinetics during early resuscitation in the intensive care unit. We hypothesized that patients with impaired microcirculation after cardiac surgery would have a more severe postoperative hyperlactatemia, represented by the lactate time-integral of an arterial blood lactate concentration greater than 2.0 mmol/L. METHODS We measured sublingual microcirculation using incident darkfield video microscopy in 50 subjects on intensive care unit admission after cardiac surgery. Serial measurements of systemic hemodynamics, blood gas, lactate, and catecholamine infusions were recorded each hour for the first 6 h after surgery. Lactate area under the curve (AUC) was calculated over the first 6 h. The lactate AUC was compared between subjects with normal and low perfused vessel density (PVD < 18 mm/mm2), high microcirculatory heterogeneity index (MHI > 0.4), and low vessel-by-vessel microvascular flow index (MFIv < 2.6). RESULTS Thirteen (26%) patients had a low postoperative PVD, 20 patients (40%) had a high MHI, and 26 (52%) patients had a low MFIv. Patients with low perfused vessel density had higher lactate AUC compared with subjects with a normal PVD (22.3 [9.4-31.0] vs. 2.6 [0-8.8]; P < 0.0001). Patients with high microcirculatory heterogeneity had a higher lactate AUC compared with those with a normal MHI (2.5 [0.1-8.2] vs. 13.1 [3.7-31.1]; P < 0.001). We did not find a difference in lactate AUC when comparing high and low MFIv. CONCLUSION Low perfused vessel density and high microcirculatory heterogeneity are associated with an increased intensity and duration of lactic acidosis after cardiac surgery with cardiopulmonary bypass.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic continues to surge in the United States and globally. OBJECTIVE To describe the epidemiology of COVID-19-related critical illness, including trends in outcomes and care delivery. DESIGN Single-health system, multihospital retrospective cohort study. SETTING 5 hospitals within the University of Pennsylvania Health System. PATIENTS Adults with COVID-19-related critical illness who were admitted to an intensive care unit (ICU) with acute respiratory failure or shock during the initial surge of the pandemic. MEASUREMENTS The primary exposure for outcomes and care delivery trend analyses was longitudinal time during the pandemic. The primary outcome was all-cause 28-day in-hospital mortality. Secondary outcomes were all-cause death at any time, receipt of mechanical ventilation (MV), and readmissions. RESULTS Among 468 patients with COVID-19-related critical illness, 319 (68.2%) were treated with MV and 121 (25.9%) with vasopressors. Outcomes were notable for an all-cause 28-day in-hospital mortality rate of 29.9%, a median ICU stay of 8 days (interquartile range [IQR], 3 to 17 days), a median hospital stay of 13 days (IQR, 7 to 25 days), and an all-cause 30-day readmission rate (among nonhospice survivors) of 10.8%. Mortality decreased over time, from 43.5% (95% CI, 31.3% to 53.8%) to 19.2% (CI, 11.6% to 26.7%) between the first and last 15-day periods in the core adjusted model, whereas patient acuity and other factors did not change. LIMITATIONS Single-health system study; use of, or highly dynamic trends in, other clinical interventions were not evaluated, nor were complications. CONCLUSION Among patients with COVID-19-related critical illness admitted to ICUs of a learning health system in the United States, mortality seemed to decrease over time despite stable patient characteristics. Further studies are necessary to confirm this result and to investigate causal mechanisms. PRIMARY FUNDING SOURCE Agency for Healthcare Research and Quality.

Abstract
OBJECTIVE Resuscitation after cardiac surgery needs to address multiple pathophysiological processes that are associated with significant morbidity and mortality. Functional microcirculatory derangements despite normal systemic hemodynamics have been previously described but must be tied to clinical outcomes. The authors hypothesized that microcirculatory dysfunction after cardiac surgery would include impaired capillary blood flow and impaired diffusive capacity and that subjects with the lowest quartile of perfused vessel density would have an increased postoperative lactate level and acute organ injury scores. DESIGN Prospective, observational study. SETTING A single, tertiary university cardiovascular surgical intensive care unit. PARTICIPANTS 25 adults undergoing elective cardiac surgery requiring cardiopulmonary bypass. INTERVENTION Sublingual microcirculation was imaged using incident dark field microscopy before and 2 to 4 hours after surgery in the intensive care unit. MEASUREMENTS AND MAIN RESULTS Compared with baseline measurements, postoperative vessel-by-vessel microvascular flow index (2.9 [2.8-2.9] v 2.5 [2.4-2.7], p < 0.0001) and perfused vessel density were significantly impaired (20.7 [19.3-22.9] v 16.3 [12.8-17.9], p < 0.0001). The lowest quartile of perfused vessel density (<12.8 mm/mm2) was associated with a significantly increased postoperative lactate level (6.0 ± 2.9 v 1.8 ± 1.2, p < 0.05), peak lactate level (7.6 ± 2.8 v 2.8 ± 1.5, p = 0.03), and sequential organ failure assessment (SOFA) score at 24 and 48 hours. CONCLUSION In patients undergoing cardiac surgery, there was a significant decrease in postoperative microcirculatory convective blood flow and diffusive capacity during early postoperative resuscitation. Severely impaired perfused vessel density, represented by the lowest quartile of distribution, is significantly related to hyperlactatemia and early organ injury.

Abstract
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.

Abstract
Coronary artery bypass grafting is a highly efficacious mode of myocardial revascularization that reduces mortality from ischemic heart disease. The patient presenting after acute myocardial infarction in cardiogenic shock presents a unique challenge. Early revascularization is proven to reduce mortality, but many questions remain, including the optimal mode and extent of revascularization, the role of mechanical circulatory support, and which patients are candidates for surgical intervention. Unprecedented attention to the outcomes of cardiac surgery means decisions about the management of the acute myocardial infarction in cardiogenic shock patients are influenced by risk aversion. The authors here review this topic to arm the reader with a comprehensive understanding of the literature to better guide surgical decision-making and perioperative management.

Abstract
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.

Abstract
BACKGROUND Despite recommendations regarding the use of intraoperative transesophageal echocardiography (TEE), there is no randomized evidence to support its use in cardiac valve surgery. The purpose of this study was to compare the clinical outcomes of patients undergoing open cardiac valve repair or replacement surgery with and without transesophageal echocardiographic monitoring. The hypothesis was that transesophageal echocardiographic monitoring would be associated with lower 30-day mortality and shorter length of hospitalization. METHODS In this observational retrospective cohort study, Medicare claims were used to test the association between perioperative TEE and 30-day all-cause mortality and length of hospitalization among patients undergoing open cardiac valve repair or replacement surgery between January 1, 2010, and October 1, 2015. Baseline characteristics were defined by inpatient and outpatient claims. Medicare death records were used to ascertain 30-day mortality. Statistical analyses included regression models and propensity score matching. RESULTS A total of 219,238 patients underwent open cardiac valve surgery, of whom 85% underwent TEE. Patients who underwent TEE were significantly older and had greater comorbidities. After adjusting for patient demographics, clinical comorbidities, surgical characteristics, and hospital factors, including annual surgical volume, the TEE group had a lower adjusted odds of 30-day mortality (odds ratio, 0.77; 95% CI, 0.73 to 0.82; P < .001), with no difference in length of hospitalization (<0.01%; 95% CI, -0.61% to 0.62%; P = .99). Results were similar across all analyses, including a propensity score-matched cohort. CONCLUSIONS Transesophageal echocardiographic monitoring in cardiac valve repair or replacement surgery was associated with lower 30-day risk-adjusted mortality, without a significant increase in length of hospitalization. These findings support the use of TEE as routine practice in open cardiac valve repair or replacement surgery.

Abstract
RATIONALE & OBJECTIVE Collaboration between nephrology consultants and intensive care unit (ICU) teams is important in light of the high incidence of acute kidney injury in today's ICUs. Although there is considerable debate about how nephrology consultants and ICU teams should collaborate, communicative dynamics between the 2 parties remain poorly understood. This article describes interactions between nephrology consultants and ICU teams in the academic medical setting. STUDY DESIGN Focused ethnography using semi-structured interviews and participant observation. SETTING & PARTICIPANTS Purposive sampling was used to enroll nephrologists, nephrology fellows, and ICU practitioners across several roles collaborating in 3 ICUs (a medical ICU, a surgical ICU, and a cardiothoracic surgical ICU) of a large urban US academic medical center. Participant observation (150 hours) and semi-structured interviews (35) continued until theoretical saturation. ANALYTICAL APPROACH Interview and fieldnote transcripts were coded in an iterative team-based process. Explanation was developed using an abductive approach. RESULTS Nephrology consultants and surgical ICU teams exhibited discordant preferences about the aggressiveness of renal replacement therapy based on different understandings of physiology, goals of care, and acuity. Collaborative difficulties resulting from this discordance led to nephrology consultants often serving as dialysis proceduralists rather than diagnosticians in surgical ICUs and to consultants sometimes choosing not to express disagreements about clinical care because of the belief that doing so would not lead to changes in the course of care. LIMITATIONS Aspects of this single-site study of an academic medical center may not be generalizable to other clinical settings and samples. Surgical team perspectives would provide further detail about nephrology consultation in surgical ICUs. The effects of findings on patient care were not examined. CONCLUSIONS Differences in approach between internal medicine-trained nephrologists and anesthesia- and surgery-trained intensivists and surgeons led to collaborative difficulties in surgical ICUs. These findings stress the need for medical teamwork research and intervention to address issues stemming from disciplinary siloing rooted in long-term socialization to different disciplinary practices.

Abstract
OBJECTIVE To test the association between transesophageal echocardiography (TEE) and incidence of acute kidney injury and length of hospitalization among United States adults undergoing isolated coronary artery bypass graft (CABG) surgery. DESIGN This was an observational, retrospective cohort analysis. SETTING This study used a multicenter claims dataset from a commercially insured population undergoing CABG surgery in the United States between 2004 and 2016. PARTICIPANTS Adults aged 18 years or older with continuous insurance enrollment and an absence of renal-related diagnoses before the index CABG surgery. INTERVENTIONS Receipt of TEE within 1 calendar day of the index CABG surgery date. MEASUREMENTS AND MAIN RESULTS Of 51,487 CABG surgeries, 5,361 (10.4%; [95% confidence interval [CI]: 10.1-10.7%]) developed acute kidney injury and the mean length of hospitalization was 8.8 days (95% CI: 8.7-8.8). The TEE group demonstrated a greater absolute risk difference (RD) for acute kidney injury by multiple linear regression, overall, (RD=+1.0; [95% CI: 0.4-1.5%]; p < 0.001) and among a low-risk subgroup (RD=+1.0; [95% CI: 0.4-1.6; p = 0.002), but not by instrumental variable analysis (RD=+0.9 [95% CI: -1.1 to 2.9%]; p = 0.362). The TEE group demonstrated a longer length of hospitalization by multiple linear regression, overall (+2.0%; [95% CI: 1.1-2.9%]; p < 0.001), among a low-risk subgroup (+2.2%; [95% CI: 1.2-3.2%]; p < 0.001), and by instrumental variable analysis (+10.3%; [95% CI: 7.0-13.7%]; p < 0.001). CONCLUSIONS TEE monitoring in CABG surgery was not associated with a lower incidence of acute kidney injury or decreased length of hospitalization. These findings highlight the importance of additional work to study the clinical effectiveness of TEE in CABG surgery.

Abstract
OBJECTIVE This study aims to determine the prevalence of functional and psychological impairment in survivors of extracorporeal life support (ECLS) and assess the needs of survivors to guide development of an effective follow-up program. DESIGN This mixed-methods outcomes study used quantitative assessment via standardized instruments (Katz Index of Independence of Activities of Daily Living [Katz ADL], the Lawton Instrumental Activities of Daily Living [Lawton IADL], Hospital Anxiety and Depression Scale, and the Post Traumatic Growth Inventory) and qualitative interview to identify challenges experienced by survivors. SETTING A single institutional experience in an academic medical center in the United States. PATIENTS Patient selection targeted patients who underwent veno-venous ECLS for acute respiratory failure between January 1, 2015, and April 1, 2017. Forty-two patients (21 male, 21 female; median age of 49 years; interquartile range 36-57 years) completed the interview a median of 14.6 (interquartile range 7.7-21.1) months after ECLS decannulation. INTERVENTIONS This was an observational follow-up study for which no intervention was made. MEASUREMENTS AND MAIN RESULTS The Katz ADL and Lawton IADL revealed high independence and functionality in 62% of patients (26 of 42). Clinically significant anxiety was present in 48% (20 of 42) of patients and depression in 26% (11 of 42). There was a correlation between the number of ADL and IADL deficiencies and depression (rho 0.61, p < 0.001) and anxiety (rho 0.29, p = 0.033) subscales of the Hospital Anxiety and Depression Scale. High levels of posttraumatic growth were noted in 50% (21 of 42) of patients. Nearly all survivors noted that a clinic designed for post-ECLS follow-up would be beneficial. Patients desired access to education, improved coordination of care, and additional mental health resources. CONCLUSIONS This study demonstrated persistent physical and psychological impairments in survivors of ECLS. Patients consistently expressed a desire to debrief on their hospital course and receive education on possible long-term effects. Study findings suggest that structured follow-up may allow for early identification of psychological and physical impairments to improve outcomes. Future studies should focus on investigating the effect of rehabilitation and follow-up clinics in preventing these issues.

Abstract
OBJECTIVES The objectives of this study were as follows: (1) to describe a successful design for a mobile lung rescue program, focusing on challenges and resources required to support such a program, and (2) report short-term outcomes for patients placed on venovenous extracorporeal life support (VV-ECLS) by a transferring team before inter-facility transport to a specialized extracorporeal life support (ECLS) center. DESIGN This retrospective review and analysis used patient chart review to collect outcomes data and resource demand. SETTING A single institutional experience in an academic center in the United States. PARTICIPANTS Patient selection targeted the 75 patients who were placed on VV-ECLS for acute respiratory failure at an outside institution by the authors' team before transport from January 1, 2015, through December 31, 2017. INTERVENTIONS No intervention was made. MEASUREMENTS AND MAIN RESULTS Average time for dispatch and transfer was 4 hours and 10 minutes for ground and 3 hours and 30 minutes for air transport (p = 0.029). Demand was highest in winter, with 61% (46/75) of patients presenting from November through April, and daytime, with 73% (55/75) occurring from 8 am to 8 pm. Demand increased during the study period, with 21 patients in 2015, 24 in 2016, and 30 in 2017. Mortality was low, with 72% of patients surviving to discharge. CONCLUSIONS Herein a successful mobile lung rescue program for transfer to a regional ECLS center is described. These findings demonstrate bed availability during high census and presence of a physician for duration of transport. These challenges can be overcome and successful implementation can be made with low mortality, supporting the development of regional ECLS centers.

Abstract
OBJECTIVE The authors sought to assess for the presence of practice variation in the use of intraoperative transesophageal echocardiography (TEE) for open cardiac valve surgery. DESIGN This study was a retrospective cohort analysis. SETTING The administrative claims data used for this investigation were multi-institutional and a representative sample of commercially insured patients in the United States between 2010 and 2015. PARTICIPANTS The cohort consisted of adult patients, aged 18 years or older, undergoing open mitral valve (MV) or aortic valve (AV) surgery. INTERVENTIONS This was an observational analysis without interventions. MEASUREMENTS AND MAIN RESULTS Of 19,386 valve surgeries, 12,313 (64%) underwent AV replacement, 6,192 (32%) underwent MV repair or replacement, and 881 (<5%) underwent both MV and AV surgery. The overall rate of intraoperative TEE was 82% (95% confidence interval [CI]: 81%-82%), less frequently observed in AV procedures compared to MV or combined MV-AV procedures (80% v 85%, p < 0.001). Rates of intraoperative TEE claims varied markedly across U.S. states. After adjustment, the relative odds of an intraoperative TEE claim ranged across states from 0.26 (Louisiana, 95% CI: 0.18-0.36; p < 0.001) to 2.10 (North Carolina, 95% CI: 1.57-2.82; p < 0.001). CONCLUSION Among adult patients undergoing open AV or MV surgery in the United States, 82% had a claim for an intraoperative TEE with marked variability across U.S. states. Increasing adherence to intraoperative TEE guidelines for valve surgery may represent an unrecognized opportunity to improve the quality of cardiac surgical care.

Abstract
Acute respiratory distress syndrome (ARDS) occurs in more than 10% of intensive care unit admissions and in nearly 25% of ventilated patients. Mortality remains high at 40%, and, for patients who survive, recovery continues for months or even years. Early recognition and minimizing further lung injury remain essential to successful management of severe ARDS. Advanced treatment strategies, which complement lung protective ventilation, include short-term neuromuscular blockade, prone positioning, and extracorporeal membrane oxygenation. Alternative ventilator strategies include high-frequency ventilation and airway pressure release ventilation. This article reviews these options in patients with severe ARDS.
