Project description:Neurologic complications following acute respiratory distress syndrome (ARDS) are well described, however, information on the neurologic outcome regarding peripheral nervous system complications in critically ill ARDS patients, especially those who received extracorporeal membrane oxygenation (ECMO) are lacking. In this prospective observational study 28 ARDS patients who survived after ECMO or conventional nonECMO treatment were examined for neurological findings. Nine patients had findings related to cranial nerve innervation, which differed between ECMO and nonECMO patients (p = 0.031). ECMO patients had severely increased patella tendon reflex (PTR) reflex levels (p = 0.027 vs. p = 0.125) as well as gastrocnemius tendon reflex (GTR) (p = 0.041 right, p = 0.149 left) were affected on the right, but not on the left side presumably associated with ECMO cannulation. Paresis (14.3% of patients) was only found in the ECMO group (p = 0.067). Paresthesia was frequent (nonECMO 53.8%, ECMO 62.5%; p = 0.064), in nonECMO most frequently due to initial trauma and polyneuropathy, in the ECMO group mainly due to impairments of N. cutaneus femoris lateralis (4 vs. 0; p = 0.031). Besides well-known central neurologic complications, more subtle complications were detected by thorough clinical examination. These findings are sufficient to hamper activities of daily living and impair quality of life and psychological health and are presumably directly related to ECMO therapy.

Project description:IntroductionExtracorporeal membrane oxygenation (ECMO) is widely used during refractory cardiac or respiratory failure, and some case reports described ECMO utilization in critical airway interventional therapy.MethodsEligible reports about patients receiving airway interventional therapy under ECMO were retrieved from Web of Science, Embase, Medline, and Cochrane databases up to 1 August 2022.ResultsForty-eight publications including 107 patients who underwent ECMO for critical airway problems met the inclusion criteria. The critical airway problem that was reported the most was tumor-associated airway obstruction (n = 66, 61.7%). The second most reported etiology was postoperative airway collapse or stenosis (n = 19, 17.8%). The main interventional therapies applied were airway stent placement or removal (n = 61, 57.0%), mass removal (n = 22, 20.6%), and endotracheal intubation (n = 12, 11.2%) by bronchoscopy. The median ECMO duration was 39.5 hours. Eleven patients had ECMO-associated complications, including seven cases of airway hemorrhage, one case of arteriovenous fistula, one case of vein rupture and hematoma, one case of foot ischemia, and one case of neuropraxia of the cannulation site. In total, 91.6% of the patients survived and were discharged from the hospital.ConclusionECMO appears to be a viable form of life support for patients undergoing interventional therapy for critical airway problems.

Project description:IntroductionIntra-abdominal hypertension (IAH) causes atelectasis, reduces lung volumes and increases respiratory system elastance. Positive end-expiratory pressure (PEEP) in the setting of IAH and healthy lungs improves lung volumes but not oxygenation. However, critically ill patients with IAH often suffer from acute lung injury (ALI). This study, therefore, examined the respiratory and cardiac effects of positive end-expiratory pressure in an animal model of IAH, with sick lungs.MethodsNine pigs were anesthetized and ventilated (48 +/- 6 kg). Lung injury was induced with oleic acid. Three levels of intra-abdominal pressure (baseline, 18, and 22 mmHg) were randomly generated. At each level of intra-abdominal pressure, three levels of PEEP were randomly applied: baseline (5 cmH2O), moderate (0.5 × intra-abdominal pressure), and high (1.0 × intra-abdominal pressure). We measured end-expiratory lung volumes, arterial oxygen levels, respiratory mechanics, and cardiac output 10 minutes after each new IAP and PEEP setting.ResultsAt baseline PEEP, IAH (22 mmHg) decreased oxygen levels (-55%, P <0.001) and end-expiratory lung volumes (-45%, P = 0.007). At IAP of 22 mmHg, moderate and high PEEP increased oxygen levels (+60%, P = 0.04 and +162%, P <0.001) and end-expiratory lung volume (+44%, P = 0.02 and +279%, P <0.001) and high PEEP reduced cardiac output (-30%, P = 0.04). Shunt and dead-space fraction inversely correlated with oxygen levels and end-expiratory lung volumes. In the presence of IAH, lung, chest wall and respiratory system elastance increased. Subsequently, PEEP decreased respiratory system elastance by decreasing chest wall elastance.ConclusionsIn a porcine sick lung model of IAH, PEEP matched to intra-abdominal pressure led to increased lung volumes and oxygenation and decreased chest wall elastance shunt and dead-space fraction. High PEEP decreased cardiac output. The study shows that lung injury influences the effects of IAH and PEEP on oxygenation and respiratory mechanics. Our findings support the application of PEEP in the setting of acute lung injury and IAH.

Project description:BackgroundVeno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been used increasingly to support patients with cardiogenic shock (CS). There has been growing recognition of the favorable and unfavorable hemodynamic effects of this therapy and recent interest in the use of other percutaneous circulatory support devices to offset some of the potentially harmful hemodynamic effects. Herein, we provide visual evidence of the effects of intra-aortic balloon pump (IABP) counterpulsation for a patient with peripheral VA-ECMO cannulation.Case presentationA 68 year old man who had undergone orthotopic heart transplantation presented with 2 days of fatigue, orthopnea, and paroxysmal nocturnal dyspnea. On examination, he was tachycardic, hypotensive and hypoxic with cool extremities, consistent with CS. Transthoracic echocardiogram (TTE) showed new severe biventricular dysfunction with a left ventricular ejection fraction of 15%, right heart catheterization demonstrated elevated filling pressures and low output. An IABP was inserted via the left femoral artery with minimal improvement in hemodynamics. He was escalated to VA-ECMO. Repeat TTE demonstrated aortic valve (AV) opening with each cardiac cycle and mild MR. With placement of the IABP on standby Additional file 1: Video 1 (video 0:03), the AV no longer opened. Re-initiation of balloon counterpulsation resulted in resumed AV opening with each beat Additional file 1: Video 1 (video 0:17). He was treated for presumed acute allograft rejection with methylprednisolone, thymoglobulin, intravenous immunoglobulin and plasmapheresis with improvement in allograft function. However, he developed an Enterobacter aerogenes pneumonia and rapidly fatal septic shock.ConclusionsThis case visually demonstrates effective LV decompression by IABP counterpulsation in VA-ECMO support. While the overall effects of LV decompression in patients on VA-ECMO with IABP are still unclear, this report demonstrates one potential mechanism of benefit in the prevention of stagnation of blood flow that may lead to intra-cardiac or aortic root thrombus formation.

Project description:BackgroundCase series have reported favorable outcomes with extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory distress syndrome. However, those patients were generally young, with few comorbid conditions.ObjectiveTo characterize the clinical features and survival rates of patients with severe acute respiratory distress syndrome who met criteria for ECMO but were managed without it.MethodsPatients who met the study criteria were identified prospectively. Inclusion criteria for ECMO included severe hypoxemia, uncompensated hypercapnia, or elevated end-inspiratory plateau pressures despite low tidal volume ventilation. Predicted survival rates with ECMO were calculated using the Respiratory ECMO Survival Prediction score.ResultsOf the 46 patients who met the criteria for severe acute respiratory distress syndrome and ECMO consideration, 5 received ECMO and 16 patients had at least 1 contraindication to it. The remaining 25 patients met ECMO criteria but did not receive the treatment. The patients' mean age was 53.5 (SD, 14.3) years; 84% had at least 1 major comorbid condition. The median predicted survival rate with ECMO was 57%. The actual hospital discharge survival rate without ECMO was 56%.ConclusionsThe general medical intensive care patient population with severe acute respiratory distress syndrome is older and sicker than patients reported in prior case series in which patients were treated with ECMO. In this study, the survival rate without ECMO was similar to predicted survival rates with ECMO.
