ABSTRACT
Interruptions in continuous nebulized pulmonary vasodilators, such as epoprostenol, can potentially result in clinical deterioration in respiratory status. Coadministration of other intermittent nebulized therapies may require opening the ventilator circuit to facilitate administration. However, in patients with SARS-CoV2 infection, it is preferred to avoid opening the circuit whenever feasible to prevent aerosolization of the virus and exposure of health care workers. In this study, we describe a unique method of administering continuous epoprostenol nebulization and intermittent nebulized antibiotics, mucolytics, and bronchodilators, using Aerogen vibrating mesh nebulizers without interruptions in epoprostenol or opening the ventilator circuit. This technique set up consisted of stacking two Aerogen nebulizer cups, each with its own controller. This approach was successful in allowing concomitant delivery of intermittent and continuous nebulized therapy without interruptions. To our knowledge, this method has not been previously described in the literature and may be helpful to bedside clinicians facing a similar clinical scenario.

BACKGROUND: Familial dysautonomia (Riley-Day syndrome, hereditary sensory autonomic neuropathy type-III) is a rare genetic disease caused by impaired development of sensory and afferent autonomic nerves. As a consequence, patients develop neurogenic dysphagia with frequent aspiration, chronic lung disease, and chemoreflex failure leading to severe sleep disordered breathing. The purpose of these guidelines is to provide recommendations for the diagnosis and treatment of respiratory disorders in familial dysautonomia. METHODS: We performed a systematic review to summarize the evidence related to our questions. When evidence was not sufficient, we used data from the New York University Familial Dysautonomia Patient Registry, a database containing ongoing prospective comprehensive clinical data from 670 cases. The evidence was summarized and discussed by a multidisciplinary panel of experts. Evidence-based and expert recommendations were then formulated, written, and graded using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. RESULTS: Recommendations were formulated for or against specific diagnostic tests and clinical interventions. Diagnostic tests reviewed included radiological evaluation, dysphagia evaluation, gastroesophageal evaluation, bronchoscopy and bronchoalveolar lavage, pulmonary function tests, laryngoscopy and polysomnography. Clinical interventions and therapies reviewed included prevention and management of aspiration, airway mucus clearance and chest physical therapy, viral respiratory infections, precautions during high altitude or air-flight travel, non-invasive ventilation during sleep, antibiotic therapy, steroid therapy, oxygen therapy, gastrostomy tube placement, Nissen fundoplication surgery, scoliosis surgery, tracheostomy and lung lobectomy. CONCLUSIONS: Expert recommendations for the diagnosis and management of respiratory disease in patients with familial dysautonomia are provided. Frequent reassessment and updating will be needed.
