Chronic Respiratory Failure (chronic + respiratory_failure)
Selected AbstractsPhysician attitudes towards ventilatory support for spinal muscular atrophy type 1 in AustralasiaJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 12 2007Nimeshan Geevasinga Background: Without ventilatory support, premature death from respiratory insufficiency is virtually universal in infants with spinal muscular atrophy type 1 (SMA1). With mechanical ventilation, however, long-term survival has been reported from numerous international centres. We aimed to characterize physician attitudes to the various forms of ventilatory support for children with SMA1. Methods: We surveyed neurologists, respiratory physicians, clinical geneticists and intensivists from all major paediatric hospitals in Australia and New Zealand regarding their views on ventilatory management of SMA1. Results: Ninety-two of the 157 (59%) physicians surveyed replied. Respondents included 16 clinical geneticists, 19 intensive care physicians, 28 neurologists and 29 respiratory physicians. Almost half (47%) opposed invasive ventilation of children with SMA1 and respiratory failure precipitated by intercurrent illness. The majority (76%) opposed invasive ventilatory support for chronic respiratory failure in SMA1. In contrast, non-invasive ventilation was felt by 85% to be appropriate for acute respiratory deteriorations, with 49% supporting long-term non-invasive ventilatory support. Most physicians felt that decisions regarding ventilation should be made jointly by parents and doctors, and that hospital Clinical Ethics Committees should be involved in the event of discordant opinion regarding further management. A majority felt that a defined hospital policy would be valuable in guiding management of SMA1. Conclusions: Respiratory support in SMA1 is an important issue with significant ethical, financial and resource management implications. Most physicians in Australian and New Zealand oppose invasive ventilatory support for chronic respiratory failure in SMA1. Non-invasive ventilation is an accepted intervention for acute respiratory decompensation and may have a role in the long-term management of SMA1. Clinical Ethics Committees and institutional policies have a place in guiding physicians and parents in the management of children with SMA1. [source] Spontaneously regressed Kaposi's sarcoma and human herpesvirus 8 infection in a human immunodeficiency virus-negative patientPATHOLOGY INTERNATIONAL, Issue 4 2000Yasuko Kondo Kaposi's sarcoma occurring in a 78-year-old woman, with the absence of the human immunodeficiency virus infection, was correctly diagnosed by immunohistochemistry using anti-human herpesvirus 8 (HHV8) antibody (PA1-73N) for the first time. The patient suffered from chronic respiratory failure and was treated with a low dose of steroids for 2.5 years. After her medication dosage was increased for the exacerbation of the respiratory failure, multiple skin tumors in her feet and legs suddenly developed. Histopathologically, skin tumors were suspected as Kaposi's sarcoma at the first biopsy and reactive angiomatosis at the second biopsy. Polymerase chain reaction and immunohistochemistry, however, revealed the presence of HHV8 DNA fragment and positive staining in the majority of spindle cells in the skin tumors. Serological examination confirmed the positivity of anti-HHV8 antibodies. HHV8 infection and steroid-induced immunosuppression, as well as environmental factors played a role in the development of Kaposi's sarcoma in this patient, because she was born in Okinawa, which is a well-known endemic area of Kaposi's sarcoma in Japan. As her general condition improved, the skin lesions regressed without any specific treatment, and disappeared completely 8 months later, in which regression may be associated with evidence of numerous CD8 cell infiltration in the second biopsy tissues. No recurrence was observed during the following 6 month follow up. [source] Home care for chronic respiratory failure in children: 15 years experiencePEDIATRIC ANESTHESIA, Issue 4 2002L. APPIERTO MD Background:,Advances in paediatric intensive care have reduced mortality but, unfortunately, one of the consequences is an increase in the number of patients with chronic diseases. It is generally agreed that home care of children requiring ventilatory support improves their outcomes and results in cost saving for the National Health Service. Methods:,Since 1985, the Children's Hospital Bambino Gesł of Rome has developed a program of paediatric home care. The program is performed by a committed Home Health Care Team (HHCT) which selects the eligible patients for home care and trains the families to treat their child. During the period January 1985 to January 2001, 53 children with chronic respiratory failure were included in the home care program. Of these, seven patients were successively excluded and six died in our intensive care unit (ICU), while one still lives in our ICU since 1997. The results obtained in the remaining 46 children are reported. Results:,The pathologies consisted of disorders of respiratory control related to brain damage (26%), upper airways obstructive disease (26%), spinal muscular atrophy (22%), myopathies and muscular dystrophies (6.5%), bronchopulmonary dysplasia (6.5%), tracheomalacia (6.5%), central hypoventilation syndrome (4.3%) and progressive congenital scoliosis (2.2%). Of these 46 patients, 34 children are mechanically ventilated and the median of their ICU stay was 109.5 days (range 54,214 days), while the remaining 12 children were breathing spontaneously and the median of their ICU stay was 90.5 days (range 61,134 days). We temporarily readmitted six patients to our ICU to perform scheduled otolaryngological surgery, eight patients for acute respiratory infections and two patients for deterioration of their neurological status due to high pressure hydrocephalus for placement of a ventriculoperitoneal shunt; these 16 patients were discharged back home again. Two other patients were readmitted for deterioration of their chronic disease and died in our ICU, while seven patients died at home. Conclusions:,Thirty-seven children are still alive at home and four of them improved their respiratory condition so that it was possible to remove the tracheostomy tube. Our oldest patient has now achieved 15 years of mechanical ventilation at home.

Edwards MD Abstract Infants and children with surgically corrected or palliated congenital heart disease (CHD) are at risk for chronic respiratory failure, necessitating home mechanical ventilation (HMV) via tracheostomy. However, very little data exists on this population or their outcomes. We conducted a retrospective chart review of all children with CHD enrolled in the Childrens Hospital Los Angeles HMV program between 1994 and 2009. Data were collected on type of heart lesion, surgeries performed, number of failed extubations, timing of tracheostomy, mortality, length of time on HMV, weaning status, associated co-morbidities, and Risk Adjusted classification for Congenital Heart Surgery (RACHS-1) category. Thirty-five children were identified; six with single ventricle anatomy, who received palliative procedures. Twenty-three (66%) patients are alive; 8 (23%) living patients have been weaned off HMV. Twelve (34%) patients are deceased. The incidence of mortality for single ventricle patients was 50%, and only one of the surviving children has received final palliation and weaned off HMV. Eight of nine patients (89%) with a RACHS score ,4 died, and none have been weaned off of HMV. The 5-year survival for all CHD HMV patients was 68%; 90% for patients with RACHS ,3; and 12% for patients with score ,4. Children with more complex lesions, as demonstrated by single ventricle physiology or greater RACHS scores, had higher mortality rates and less success weaning off HMV. This case series suggests that caregivers should give serious consideration to the type of heart defect as they advise families considering HMV in children with CHD.

[source] Home mechanical ventilation in children: Retrospective survey of a pediatric populationPEDIATRICS INTERNATIONAL, Issue 6 2007GIANCARLO OTTONELLO Abstract Background: Home care support is beneficial for children needing mechanical ventilation, when clinically stable. Methods: A retrospective analysis was carried out of the long-term home ventilation management of a pediatric population with chronic respiratory failure composed of 20 ventilator-dependent children categorized according to age, diagnosis and ventilation support. Age groups consisted of 10% under 1 year, 30% between 2 and 5 years, 30% between 6 and 12 years, and 30% older than 12 years. Diagnostic categories included myopathic disorder, n = 5; congenital central hypoventilation syndrome, n = 6; chest wall disorder, n = 5; cystic fibrosis, n = 1; pulmonary hypertension, n = 1; and diaphragmatic paralysis, n = 2. Results: Sixty-five percent were ventilated using non-invasive mode (NIMV): eight with nasal mask, five with full-face mask, and two children in NIMV also used negative pressure mode; 35% were ventilated using tracheostomy, one of them also used a diaphragmatic pacer. Seventy percent needed nocturnal ventilatory support, (20% 12,18 h, 10% full-day). A total of 18 children were included in the home care and follow-up program. Two children died: one because of worsening of his chronic disease and one because of septic shock. Conclusion: Although home care ventilation is not yet widely diffused, it represents a valid alternative to long hospitalization for children with stable chronic respiratory failure.
