Extracorporeal Membrane Oxygenation for Pediatric Patients With Coronavirus Disease 2019-Related Illness.

ABSTRACT: OBJECTIVE:To describe current hospital guidelines and the opinions of extracorporeal membrane oxygenation leaders at U.S. children's hospitals concerning the use of extracorporeal membrane oxygenation for coronavirus disease 2019-positive pediatric patients. DESIGN:Confidential, self-administered questionnaire. SETTING:One hundred twenty-seven U.S. pediatric extracorporeal membrane oxygenation centers. SUBJECTS:Extracorporeal membrane oxygenation center program directors and coordinators. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:In March 2020, a survey was sent to 127 pediatric extracorporeal membrane oxygenation centers asking them to report their current hospital extracorporeal membrane oxygenation guidelines for coronavirus disease 2019-positive patients. Respondents were also asked their opinion on three ethical dilemmas including: prioritization of children over adults for extracorporeal membrane oxygenation use, institution of do-not-resuscitate orders, and the use of extracorporeal cardiopulmonary resuscitation for coronavirus disease 2019-positive patients. Forty-seven extracorporeal membrane oxygenation centers had enacted guidelines including 46 (100%) that offer venovenous-extracorporeal membrane oxygenation and 42 (89%) that offer venoarterial-extracorporeal membrane oxygenation for coronavirus disease 2019-positive pediatric patients. Forty-four centers (94%) stated that the indications for extracorporeal membrane oxygenation candidacy in coronavirus disease 2019 disease were similar to those used in other viral illnesses, such as respiratory syncytial virus or influenza. Most program directors (98%) did not endorse that children hospitalized with coronavirus disease 2019 should be made do-not-resuscitate and had variable opinions on whether children should be given higher priority over adults when rationing extracorporeal membrane oxygenation. Over half of program directors (60%) did not support the use of extracorporeal cardiopulmonary resuscitation for coronavirus disease 2019. CONCLUSIONS:The majority of pediatric extracorporeal membrane oxygenation centers have proactively established guidelines for the use of extracorporeal membrane oxygenation for coronavirus disease 2019-related illnesses. Further work is needed to help guide the fair allocation of extracorporeal membrane oxygenation resources and to determine the appropriateness of extracorporeal cardiopulmonary resuscitation.

Project description:ObjectivesVenovenous extracorporeal membrane oxygenation has been largely used in patients with refractory acute respiratory distress syndrome due to coronavirus disease 2019. Few data on long-term pulmonary function among venovenous extracorporeal membrane oxygenation survivors are available.DesignRetrospective, observational cohort.SettingTwo mixed medical-surgical tertiary (30 beds) and secondary (22 beds) ICUs.PatientsAll critically ill adult coronavirus disease 2019 survivors treated with venovenous extracorporeal membrane oxygenation between March 10, and April 30, 2020.Measurements and main resultsThe last available lung function and 6-minute walking tests, performed after a median of 178 days (ranges, 72-232 d) from ICU admission, were analyzed. Among the 32 coronavirus disease 2019 patients treated by venovenous extracorporeal membrane oxygenation during the study period, 11 (34%; median age 56 yr; median duration of mechanical ventilation and extracorporeal membrane oxygenation therapy of 26 and 15 d, respectively) were successfully weaned and discharged home. Spirometry was performed in nine patients; the volumetric lung function was preserved, that is, median forced vital capacity was 83% of predicted value (51-99% of predicted value), and median forced expiratory volume in 1 second was 82% of predicted value (60-99% of predicted value). Also, the median residual volume and the lung capacity were 100% of predicted value (50-140% of predicted value) and 90% of predicted value (50-100% of predicted value); only the diffusion capacity of the lung for carbon monoxide and 6-minute walking test were decreased (58% of predicted value [37-95% of predicted value] and 468 meters (365-625 meters), corresponding to [63-90% of predicted value], respectively).ConclusionsAmong survivors from severe coronavirus disease 2019 pneumonia treated with venovenous extracorporeal membrane oxygenation, preserved long-term volumetric lung function with decreased diffusion capacity of lung carbon monoxide was observed.

Project description:ObjectiveTo evaluate the performance of the extracorporeal membrane oxygenation retrieval team at a high-volume extracorporeal membrane oxygenation center during the coronavirus disease 2019 pandemic.DesignObservational study including all adult patients with confirmed infection due to severe acute respiratory syndrome coronavirus-2 cannulated at other centers and transported on extracorporeal membrane oxygenation to the ICU of the Vall d'Hebron University Hospital between 15 March and 10 June 2020.SettingThe ICU (capacity expanded to 200 during the pandemic) of the Vall d'Hebron University Hospital (a 1,100-bed public university hospital in Barcelona), the referral center for extracorporeal respiratory support in Catalonia (7.5 million inhabitants).PatientsExtracorporeal membrane oxygenation was considered if the Pao2/Fio2 ratio less than 80 mm Hg (refractory to prone position) and/or Paco2 greater than 80 mm Hg and pH less than 7.25 for more than 6 hours, and no contraindications for extracorporeal support were present.InterventionsVenovenous extracorporeal membrane oxygenation was initiated in the primary center. Then, patients were transferred to the ICU of the Vall d'Hebron University Hospital where they received support until respiratory improvement. After decannulation, patients were discharged for rehabilitation at the primary center.Measurements and main resultsNineteen patients with severe acute respiratory syndrome coronavirus-2 infection and with a mean Pao2/Fio2 ratio of 71 mm Hg (57-118 mm Hg) despite prone positioning and a mean Paco2 of 70 mm Hg (47-110 mm Hg) were transferred to our center from their primary hospital after cannulation and received venovenous extracorporeal membrane oxygenation support. Prior to cannulation, six patients (31.5%) presented vascular thrombosis, and nine (47.4%) were already receiving anticoagulant therapy. Eighteen transfers were carried out with no significant complications. While on extracorporeal membrane oxygenation, thrombotic events were recorded in nine patients (47.4%) and hemorrhagic events in 13 (68.4%). Thirteen patients (68.4%) were successfully weaned, and 12 (63.1%) were discharged home.ConclusionsExtracorporeal membrane oxygenation retrieval can rescue young, previously healthy patients with severe coronavirus disease 2019 in whom all the conventional respiratory measures have failed. Thrombotic and hemorrhagic complications are frequent in this cohort.

Project description:ObjectivesThe study investigated the impact of prone positioning during venovenous extracorporeal membrane oxygenation support for coronavirus disease 2019 acute respiratory failure on the patient outcome.DesignAn observational study of venovenous extracorporeal membrane oxygenation patients. We used a multistate survival model to compare the outcomes of patients treated with or without prone positioning during extracorporeal membrane oxygenation, which incorporates the dynamic nature of prone positioning and adjusts for potential confounders.SettingSeventy-two international institutions participating in the Coronavirus Disease 2019 Critical Care Consortium international registry.PatientsCoronavirus disease 2019 patients who were supported by venovenous extracorporeal membrane oxygenation during the study period.InterventionNone.Measurements and main resultsThere were 232 coronavirus disease 2019 patients at 72 participating institutions who were supported with venovenous extracorporeal membrane oxygenation during the study period from February 16, 2020, to October 31, 2020. Proning was used in 176 patients (76%) before initiation of extracorporeal membrane oxygenation and in 67 patients (29%) during extracorporeal membrane oxygenation. Survival to hospital discharge was 33% in the extracorporeal membrane oxygenation prone group versus 22% in the extracorporeal membrane oxygenation supine group. Prone positioning during extracorporeal membrane oxygenation support was associated with reduced mortality (hazard ratio, 0.31; 95% CI, 0.14-0.68).ConclusionsOur study highlights that prone positioning during venovenous extracorporeal membrane oxygenation support for refractory coronavirus disease 2019-related acute respiratory distress syndrome is associated with reduced mortality. Given the observational nature of the study, a randomized controlled trial of prone positioning on venovenous extracorporeal membrane oxygenation is needed to confirm these findings.

Project description:ObjectivesTo describe three coronavirus disease 2019 patients suffering from acute respiratory distress syndrome under venovenous extracorporeal membrane oxygenation therapy and tight anticoagulation monitoring presenting a novel pattern of multifocal brain hemorrhage in various degrees in all cerebral and cerebellar lobes.DesignClinical observation of three patients. Post mortem examinations.SettingTwo ICUs at the University Hospital Erlangen.PatientsThree patients (medium age 56.6 yr, two male with hypertension and diabetes, one female with no medical history) developed severe acute respiratory distress syndrome on the basis of a severe acute respiratory syndrome coronavirus 2 infection. All required mechanical ventilation and venovenous extracorporeal membrane oxygenation support.InterventionsClinical observation, CT, data extraction from electronic medical records, and post mortem examinations.Main resultsWe report on an unusual multifocal bleeding pattern in the white matter in three cases with severe acute respiratory distress syndrome due to coronavirus disease 2019 undergoing venovenous extracorporeal membrane oxygenation therapy. Bleeding pattern with consecutive herniation was found in CT scans as well as in neuropathologic post mortem examinations. Frequency for this unusual brain hemorrhage in coronavirus disease 2019 patients with extracorporeal membrane oxygenation therapy at our hospital is currently 50%, whereas bleeding events in extracorporeal membrane oxygenation patients generally occur at 10-15%.ConclusionsMultifocality and high frequency of the unusual white matter hemorrhage pattern suggest a coherence to coronavirus disease 2019. Neuropathological analyses showed circumscribed thrombotic cerebrovascular occlusions, which eventually led to microvascular and later on macrovascular disseminated bleeding events. However, signs of cerebrovascular inflammation could not be detected. Polymerase chain reaction analyses of brain tissue or cerebrospinal fluid remained negative. Increased susceptibility for fatal bleeding events should be taken into consideration in terms of systemic anticoagulation strategies in coronavirus disease 2019.
