Early Mobilization during Extracorporeal Membrane Oxygenation for Cardiopulmonary Failure in Adults: Factors Associated with Intensity of Treatment.

Rationale: Early mobilization of extracorporeal membrane oxygenation (ECMO)-supported patients is increasingly common, but it remains unknown whether there are factors predictive of achieving higher intensity mobilization among those able to participate in physical therapy. Additionally, data regarding the safety and feasibility of early mobilization with femoral cannulation, particularly ambulation, are sparse. Objectives: To determine whether there are factors associated with achieving out-of-bed versus in-bed physical therapy in ECMO-supported patients participating in physical therapy, and whether mobilization with femoral cannulation is safe and feasible. Methods: This large, single-center, retrospective study evaluated adult patients who performed active physical therapy while receiving ECMO. Mixed effects modeling was used to identify predictors of out-of-bed versus in-bed activity. Rates of mobilization with femoral cannulation and adverse events were also reported. Results: Between April 2009 and January 2020, 511 patients were supported with ECMO in a single medical intensive care unit, of whom 177 (35%) underwent active physical therapy and were included in the analysis, including 124 of 141 (88%) bridge to lung transplantation and 53 of 370 (14%) bridge to recovery. These 177 patients accounted for 2,706 active physical therapy sessions, with 138 patients (78%) achieving out-of-bed activity. In total, 108 (61%) patients ambulated (1,284 sessions), 34 of whom had femoral cannulae (250 sessions). Bridge-to-transplant (odds ratio [OR], 17.2; 95% confidence interval [CI], 4.12-72.1), venovenous ECMO (OR, 2.83; 95% CI, 1.29-6.22), later cannulation year (OR, 1.65; 95% CI, 1.37-1.98) and higher Charlson comorbidity index (OR, 1.53; 95% CI, 1.07-2.19) were associated with increased odds of achieving out-of-bed versus in-bed physical therapy, whereas invasive mechanical ventilation (OR, 0.11; 95% CI, 0.05-0.25) and femoral cannulation (OR, 0.19; 95% CI, 0.04-0.92) were associated with decreased odds of performing out-of-bed activities. Adverse events occurred in 2% of sessions. Conclusions: Several patient- and ECMO-related factors were associated with achieving higher intensity of early mobilization in patients participating in rehabilitation. Physical therapy with femoral cannulation was safe and feasible, and complications related to mobilization were uncommon.

Developing and Implementing a Dedicated Prone Positioning Team for Mechanically Ventilated ARDS Patients During the COVID-19 Crisis.

BACKGROUND: The spread of the COVID-19 pandemic in China demonstrated at an early stage the high rate of moderate to severe acute respiratory distress syndrome (ARDS) in the patient population. An intervention that has proved beneficial is the use of prone positioning (PP) for mechanically ventilated patients with ARDS. In one institution, PP was practiced in the medical ICU for this population. However, with the dramatically increasing patient load, staff anticipated that greater capacity to provide this treatment to all qualifying patients would be required. METHODS: A group of physical therapists and occupational therapists (PT/OTs) with ICU experience was redeployed from their regular roles to receive training in PP from an experienced medical ICU (MICU) RN. After intensive training, the team was ready to provide PP to patients. As the workload increased, additional PT/OTs were recruited to the team. A coordinating structure comprising attending pulmonologists screened and advised on appropriate patients. A communication and feedback structure was also implemented. RESULTS: Over a period of seven weeks, the team provided PP to more than 100 patients, with 577 individual interventions in a total of 14 ICUs and one emergency department. There were no major airway or central venous access complications, and only one anterior pressure injury was recorded. CONCLUSION: The rapid implementation of an interdisciplinary PP team in a crisis situation is feasible. It can provide a safe and efficient alternative to adding to the workload of an overloaded nursing staff.

Rapid implementation of a mobile prone team during the COVID-19 pandemic.

PURPOSE: The coronavirus disease 2019 (COVID-19) is associated with high rates of acute respiratory distress syndrome (ARDS). Prone positioning improves mortality in moderate-to-severe ARDS. Strategies to increase prone positioning under crisis conditions are needed. MATERIAL AND METHODS: We describe the development of a mobile prone team during the height of the crisis in New York City and describe characteristics and outcomes of mechanically ventilated patients who received prone positioning between April 2, 2020 and April 30, 2020. RESULTS: Ninety patients underwent prone positioning for moderate-to-severe ARDS. Sixty-six patients (73.3%) were men, with a median age of 64 years (IQR 53-71), and the median PaO2:FiO2 ratio was 107 (IQR 85-140) prior to prone positioning. Patients required an average of 3 ± 2.2 prone sessions and the median time of each prone session was 19 h (IQR 17.5-20.75). By the end of the study period, proning was discontinued in sixty-seven (65.1%) cases due to clinical improvement, twenty (19.4%) cases due to lack of clinical improvement, six (5.8%) cases for clinical worsening, and ten (9.7%) cases due to a contraindication. CONCLUSION: The rapid development of a mobile prone team safely provided prone positioning to a large number of COVID-19 patients with moderate-to-severe ARDS.
