INTRODUCTION: Critical illness is a well-recognized cause of neuromuscular weakness and impaired physical functioning. Physical therapy (PT) has been demonstrated to be safe and effective for critically ill patients. The impact of such an intervention on patients receiving extracorporeal membrane oxygenation (ECMO) has not been well characterized. We describe the feasibility and impact of active PT on ECMO patients. METHODS: We performed a retrospective cohort study of 100 consecutive patients receiving ECMO in the medical intensive care unit of a university hospital. RESULTS: Of the 100 patients receiving ECMO, 35 (35%) participated in active PT; 19 as bridge to transplant and 16 as bridge to recovery. Duration of ECMO was 14.3 ± 10.9 days. Patients received 7.2 ± 6.5 PT sessions while on ECMO. During PT sessions, 18 patients (51%) ambulated (median distance 175 feet, range 4 to 2,800) and 9 patients were on vasopressors. Whilst receiving ECMO, 23 patients were liberated from invasive mechanical ventilation. Of the 16 bridge to recovery patients, 14 (88%) survived to discharge; 10 bridge to transplant patients (53%) survived to transplantation, with 9 (90%) surviving to discharge. Of the 23 survivors, 13 (57%) went directly home, 8 (35%) went to acute rehabilitation, and 2 (9%) went to subacute rehabilitation. There were no PT-related complications. CONCLUSIONS: Active PT, including ambulation, can be achieved safely and reliably in ECMO patients when an experienced, multidisciplinary team is utilized. More research is needed to define the barriers to PT and the impact on survival and long-term functional, neurocognitive outcomes in this population.

BACKGROUND: Survivors of aneurysmal subarachnoid hemorrhage (SAH) are faced with a complicated recovery, which typically includes surgery, prolonged monitoring in the intensive care unit, and treatment focusing on the prevention of complications. OBJECTIVE: The purpose of this study was to determine the safety and feasibility of an early mobilization program for patients with aneurysmal SAH. DESIGN: This study was a retrospective analysis. METHODS: Twenty-five patients received early mobilization by a physical therapist or an occupational therapist, or both, which focused on functional training and therapeutic exercise in more progressively upright positions. Participation criteria focused on neurologic and physiologic stability prior to the initiation of early mobilization program sessions. RESULTS: Patients met the criteria for participation in 86.1% of the early mobilization program sessions attempted. Patients did not meet criteria for the following reasons: Lindegaard ratio >3.0 or middle cerebral artery (MCA) mean flow velocity (MFV) >120 cm/s (8.1%), mean arterial pressure (MAP) <80 mm Hg (1.8%), intracranial pressure (ICP) >15 mm Hg (1.8%), unable to open eyes in response to voice (0.9%), respiratory rate >40 breaths/min (0.6%), MAP >110 mm Hg (0.3%), and heart rate <40 bpm (0.3%). Adverse events occurred in 5.9% of early mobilization program sessions for the following reasons: MAP <70 mm Hg (3.1%) or >120 mm Hg (2.4%) and heart rate >130 bpm (0.3%). The 30-day mortality rate for all patients was 0%. Participation in the early mobilization program began a mean of 3.2 days (SD=1.3) after aneurysmal SAH, and patients received an average of 11.4 sessions (SD=4.3). Patients required a mean of 5.4 days (SD=4.2) to participate in out-of-bed activity and a mean of 10.7 days (SD=6.2) to walk ≥15.24 m (50 ft). CONCLUSIONS: The results of this study suggest that an early mobilization program for patients with aneurysmal SAH is safe and feasible.

PURPOSE: The purposes were to assess the functional recovery of those who survived a prolonged intensive care unit (ICU) stay by reporting the proportion who were able to ambulate independently at hospital discharge and also to examine if the time duration between admission and when the patient first stood impacted on their capacity to ambulate at discharge. MATERIALS AND METHODS: A retrospective review was conducted of medical records of ICU patients in 2007 to 2008, who were mechanically ventilated for 168 hours or more, and survived their acute care stay. Main outcome measures were (1) ambulation status before admission and at time of hospital discharge and (2) time between admission to the ICU and when the patient first stood. RESULTS: A total of 190 patients were included. Before admission, 189 (99%; 95% confidence interval [CI], 98%-100%) were ambulating independently, of whom 180 (95%) did not require a gait aid. On discharge from acute care, 89 (47%; 95% CI, 40%-54%) were ambulating independently, of whom 54 (61%) did not require a gait aid. Compared with those who stood within 30 days of ICU admission, a delay in standing of between 30 and 60 days increased the odds 5-fold (95% CI, 2-11) of being unable to ambulate independently at the time of discharge. CONCLUSIONS: After a prolonged ICU admission, more than 50% of patients were unable to ambulate independently by hospital discharge, with the time between admission and first stand, being an important predictor of this outcome.

BACKGROUND: Prolonged immobilization may harm intensive care unit (ICU) patients, and early mobilization has been proposed to counteract that process. We describe our experience in early rehabilitation of ICU patients, and its effects on physiologic outcomes. METHODS: We included all patients who stayed in our 14-bed medical ICU for > or = 7 days and received invasive mechanical ventilation for > or = 2 days. The rehabilitation program included chair-sitting, tilting-up (with arms supported or unsupported), and walking. We collected vital signs before and after each intervention. RESULTS: Over a 5-month period we studied 20 patients, after a median ICU stay of 5 days. A contraindication to the intervention was present on 230 days (43%). Sedation (15%), shock (11%), and renal support (9%) were the most frequent contraindications. We obtained complete data from 275 of 424 interventions, 33% of which were performed during mechanical ventilation. The chair-sitting intervention was the most frequent (56%), followed by the tilting-up-with-arms-unsupported intervention (25%), the walking intervention (11%), and the tilting-up arms-supported intervention (8%). The chair-sitting intervention was associated with a significant (P = .03) decline in both heart rate (mean -3.5 beats/min, 95% confidence interval [CI] -6.5 to -0.4 beats/min) and respiratory rate (-1.4 breaths/min, 95% CI -2.6 to 0.1 breaths/min), whereas blood oxygen saturation (measured via pulse oximetry [S(pO(2))]) and mean arterial blood pressure did not change significantly. Heart rate and respiratory rate similarly increased with tilting-up: 14.6 beats/min, 95% CI 10.8 to 18.4 beats/min, and 5.5 breaths/min, 95% CI 3.6 to 7.3 breaths/min with arms unsupported, and 12.4 beats/min, 95% CI 7.0 to 17.9 beats/min and 2.6 breaths/min, 95% CI -0.4 to 5.7 breaths/min with arms supported). Heart rate and respiratory rate also increased with the walking intervention: 6.9 beats/min, 95% CI 2.6 to 11.1 beats/min, and 5.9 breaths/min, 95% CI 3.8 to 8.0 breaths/min. The walking intervention significantly decreased S(pO(2)). An adverse event occurred in 13 (3%) of 424 interventions, but none had harmful consequences. CONCLUSIONS: Early rehabilitation is feasible and safe in patients in the ICU for longer than 1 week. The chair-sitting intervention was associated with nonsignificant oxygenation improvement. The tilting-up intervention was an effort as intense as walking.

Objective: Physical and occupational therapy are possible immediately after intubation in mechanically ventilated medical intensive care unit patients. The objective of this study was to describe a protocol of daily sedative interruption and early physical and occupational therapy and to specify details of intensive care unit-based therapy, including neurocognitive state, potential barriers, and adverse events related to this intervention. Design and Patients: Detailed descriptive study of the intervention arm of a trial of mechanically ventilated patients receiving early physical and occupational therapy. Setting: Two tertiary care academic medical centers participating in a randomized controlled trial. Intervention: Patients underwent daily sedative interruption followed by physical and occupational therapy every hospital day until achieving independent functional status. Therapy began with active range of motion and progressed to activities of daily living, sitting, standing, and walking as tolerated. Measurements and Main Results: Forty-nine mechanically ventilated patients received early physical and occupational therapy occurring a median of 1.5 days (range, 1.0-2.1 days) after intubation. Therapy was provided on 90% of MICU days during mechanical ventilation. While endotracheally intubated, subjects sat at the edge of the bed in 69% of all physical and occupational therapy sessions, transferred from bed to chair in 33%, stood in 33%, and ambulated during 15% (n = 26 of 168) of all physical and occupational therapy sessions (median distance of 15 feet; range, 15-20 feet). At least one potential barrier to mobilization during mechanical ventilation (acute lung injury, vasoactive medication administration, delirium, renal replacement therapy, or body mass index ≥30 kg/m) was present in 89% of patient encounters. Therapy was interrupted prematurely in 4% of all sessions, most commonly for patient-ventilator asynchrony and agitation. Conclusion: Early physical and occupational therapy is feasible from the onset of mechanical ventilation despite high illness acuity and presence of life support devices. Adverse events are uncommon, even in this high-risk group. Copyright © 2010 by the Society of Critical Care Medicine and Lippincott Williams & Wilkins.

OBJECTIVES: To (1) reduce deep sedation and delirium to permit mobilization, (2) increase the frequency of rehabilitation consultations and treatments to improve patients' functional mobility, and (3) evaluate effects on length of stay. DESIGN: Seven-month prospective before/after quality improvement project. SETTING: Sixteen-bed medical intensive care unit (MICU) in academic hospital. PARTICIPANTS: 57 patients mechanically ventilated 4 days or longer. INTERVENTION: A multidisciplinary team focused on reducing heavy sedation and increasing MICU staffing to include full-time physical and occupational therapists with new consultation guidelines. MAIN OUTCOME MEASURES: Sedation and delirium status, rehabilitation treatments, functional mobility. RESULTS: Compared with before the quality improvement project, benzodiazepine use decreased markedly (proportion of MICU days that patients received benzodiazepines [50% vs 25%, P=.002]), with lower median daily sedative doses (47 vs 15 mg midazolam equivalents [P=.09] and 71 vs 24 mg morphine equivalents [P=.01]). Patients had improved sedation and delirium status (MICU days alert [30% vs 67%, P<.001] and not delirious [21% vs 53%, P=.003]). There were a greater median number of rehabilitation treatments per patient (1 vs 7, P<.001) with a higher level of functional mobility (treatments involving sitting or greater mobility, 56% vs 78%, P=.03). Hospital administrative data demonstrated that across all MICU patients, there was a decrease in intensive care unit and hospital length of stay by 2.1 (95% confidence interval: 0.4-3.8) and 3.1 (0.3-5.9) days, respectively, and a 20% increase in MICU admissions compared with the same period in the prior year. CONCLUSIONS: Using a quality improvement process, intensive care unit delirium, physical rehabilitation, and functional mobility were markedly improved and associated with decreased length of stay.

BACKGROUND: Long-term complications of critical illness include intensive care unit (ICU)-acquired weakness and neuropsychiatric disease. Immobilisation secondary to sedation might potentiate these problems. We assessed the efficacy of combining daily interruption of sedation with physical and occupational therapy on functional outcomes in patients receiving mechanical ventilation in intensive care. Methods Sedated adults (≥18 years of age) in the ICU who had been on mechanical ventilation for less than 72 h, were expected to continue for at least 24 h, and who met criteria for baseline functional independence were eligible for enrolment in this randomised controlled trial at two university hospitals. We randomly assigned 104 patients by computer-generated, permuted block randomisation to early exercise and mobilisation (physical and occupational therapy) during periods of daily interruption of sedation (intervention; n=49) or to daily interruption of sedation with therapy as ordered by the primary care team (control; n=55). The primary endpoint—the number of patients returning to independent functional status at hospital discharge—was defined as the ability to perform six activities of daily living and the ability to walk independently. Therapists who undertook patient assessments were blinded to treatment assignment. Secondary endpoints included duration of delirium and ventilator-free days during the first 28 days of hospital stay. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00322010. FINDINGS: All 104 patients were included in the analysis. Return to independent functional status at hospital discharge occurred in 29 (59%) patients in the intervention group compared with 19 (35%) patients in the control group (p=0.02; odds ratio 2.7 [95% CI 1.2–6.1]). Patients in the intervention group had shorter duration of delirium (median 2.0 days, IQR 0.0–6.0 vs 4.0 days, 2.0–8.0; p=0.02), and more ventilator-free days (23.5 days, 7.4–25.6 vs 21.1 days, 0.0–23.8; p=0.05) during the 28-day follow-up period than did controls. There was one serious adverse event in 498 therapy sessions (desaturation less than 80%). Discontinuation of therapy as a result of patient instability occurred in 19 (4%) of all sessions, most commonly for perceived patient-ventilator asynchrony. INTERPRETATION: A strategy for whole-body rehabilitation—consisting of interruption of sedation and physical and occupational therapy in the earliest days of critical illness—was safe and well tolerated, and resulted in better functional outcomes at hospital discharge, a shorter duration of delirium, and more ventilator-free days compared with standard care.

OBJECTIVE: Ambulation of patients with acute respiratory failure may be unnecessarily limited in the acute intensive care setting. We hypothesized that ambulation of patients with acute respiratory failure would increase with transfer to an intensive care unit where activity is a key component of patient care. DESIGN: Pre-post cohort study of respiratory failure patients. SETTING: Adult intensive care units at LDS Hospital. PATIENTS: Respiratory failure patients requiring >4 days of mechanical ventilation who were transferred from other LDS Hospital intensive care units to the respiratory intensive care unit. INTERVENTIONS: We prospectively applied an early activity protocol to all consecutive respiratory failure patients transferred to the respiratory intensive care unit. MEASUREMENTS AND MAIN RESULTS: We studied 104 respiratory failure patients who required mechanical ventilation for >4 days. Transferring a patient to the respiratory intensive care unit substantially increased the probability of ambulation (p < .0001). After 2 days in the respiratory intensive care unit, the number of patients ambulating had increased three-fold compared with pretransfer rates. Female gender (p = .019), the absence of sedatives (p = .009), and lower Acute Physiology and Chronic Health Evaluation II scores (p = .017) also predicted an increased probability of ambulation. Improvements in ambulation with transfer to the respiratory intensive care unit remained significant after adjustment for Acute Physiology and Chronic Health Evaluation II scores and other covariates. CONCLUSIONS: Transfer of acute respiratory failure patients to the respiratory intensive care unit substantially improved ambulation, independent of the underlying pathophysiology. The intensive care environment may contribute unnecessary immobilization throughout the course of acute respiratory failure. Sedatives, even given intermittently, substantially reduce the likelihood of ambulation. Controlled studies are needed to determine whether intensive care unit immobilization contributes to long-term neuromuscular dysfunction or whether early intensive care unit activity improves outcomes.

OBJECTIVE: To determine whether early activity is feasible and safe in respiratory failure patients. DESIGN: Prospective cohort study. SETTING: From June 1, 2003, through December 31, 2003, we assessed safety and feasibility of early activity in all consecutive respiratory failure patients who required mechanical ventilation for >4 days admitted to our respiratory intensive care unit (RICU). A majority of patients were treated in another intensive care unit (ICU) before RICU admission. We excluded patients who required mechanical ventilation for < or =4 days. PATIENTS: Eight-bed RICU at LDS Hospital. INTERVENTIONS: We assessed patients for early activity as part of routine respiratory ICU care. We prospectively recorded activity events and adverse events. We defined three activity events as sit on bed, sit in chair, and ambulate. We defined six activity-related adverse events as fall to knees, tube removal, systolic blood pressure >200 mm Hg, systolic blood pressure <90 mm Hg, oxygen desaturation <80%, and extubation. MEASUREMENTS AND MAIN RESULTS: During the study period, we conducted a total of 1,449 activity events in 103 patients. The activity events included 233 (16%) sit on bed, 454 (31%) sit in chair, and 762 (53%) ambulate. In patients with an endotracheal tube in place, there were a total of 593 activity events, of which 249 (42%) were ambulation. There were <1% activity-related adverse events, including fall to the knees without injury, feeding tube removal, systolic blood pressure >200 mm Hg, systolic blood pressure <90 mm Hg, and desaturation <80%. No patient was extubated during activity. CONCLUSIONS: We conclude that early activity is feasible and safe in respiratory failure patients. A majority of survivors (69%) were able to ambulate >100 feet at RICU discharge. Early activity is a candidate therapy to prevent or treat the neuromuscular complications of critical illness.

BACKGROUND AND PURPOSE: Patients requiring prolonged mechanical ventilation (PMV) are frequently deconditioned because of respiratory failure precipitated by the underlying disease, the adverse effects of medications, and a period of prolonged immobilization. The effects of 6 weeks of physical training on the strength of respiratory and limb muscles, on ventilator-free time, and on functional status in patients requiring PMV were examined. SUBJECTS: Thirty-nine patients with PMV were initially enrolled in the study and were assigned to either a treatment group (n=20) or a control group (n=19). Three subjects in the treatment group and 4 subjects in the control group died during the 6-week intervention period and thus their data were excluded from the final analysis. METHODS: Subjects in the treatment group received physical training 5 days a week for 6 weeks. Strength of respiratory and limb muscles, ventilator-free time, and functional status, which was measured by the Barthel Index of Activities of Daily Living (BI) and Functional Independence Measure (FIM), were examined at baseline and at the third and sixth weeks of the study period. RESULTS: Respiratory and limb muscle strength improved significantly at the third and sixth weeks in the treatment group compared with baseline measurements. Total BI and FIM scores increased significantly in the treatment group and remained unchanged in the control group. Effect sizes of the BI and FIM scores were 2.02 and 1.93, respectively, at the sixth week. DISCUSSION AND CONCLUSION: The results show that a 6-week physical training program may improve limb muscle strength and ventilator-free time and thus improve functional outcomes in patients requiring PMV.
