AI Article Synopsis

  • - Children with hereditary neuromuscular diseases (NMDs) often face serious respiratory challenges, and home mechanical ventilation (HMV) has been life-saving, though there is a lack of established guidelines regarding its use.
  • - A study of 57 children with childhood-onset NMDs revealed that many required emergency ventilation before diagnosis, but post-HMV hospitalization rates were significantly lower than pre-HMV rates, indicating improved respiratory health.
  • - The findings highlight the importance of early diagnosis and timely use of HMV, particularly for those with spinal muscular atrophy (SMA), emphasizing that treatment decisions should consider the patient's age and ability to tolerate noninvasive ventilation (NIV).

Article Abstract

Introduction: Children with hereditary neuromuscular diseases (NMDs) are at a high risk of morbidity and mortality related to respiratory failure. The use of home mechanical ventilation (HMV) has saved the lives of many children with NMD but, due to a lack of studies, dependable guidelines are not available. We drew upon our experience to compare the various underlying NMDs and to evaluate HMV with regard to respiratory morbidity, the proper indications and timing for its use, and to develop a policy to improve the quality of home noninvasive ventilation (NIV).

Methods: We retrospectively analyzed the medical records of 57 children with childhood-onset hereditary NMDs in whom HMV was initiated between January 2000 and May 2013 at Seoul National University Children's Hospital. The degree of respiratory morbidity was estimated by the frequency and duration of hospitalizations caused by respiratory distress.

Results: The most common NMD was spinal muscular atrophy (SMA, n = 33). Emergent mechanical ventilation was initiated in 44% of the patients before the confirmed diagnosis, and the indicators of pre-HMV respiratory morbidity (e.g., extubation trials, hypoxia, hospitalizations, and intensive care unit stay) were greater in these patients than in others. The proportion of post-HMV hospitalizations (range, 0.00-0.52; median, 0.01) was lower than that of pre-HMV hospitalizations (0.02-1.00; 0.99) (P < 0.001). Eight patients were able to maintain home NIV. The main causes of NIV failure were air leakage and a large amount of airway secretions.

Conclusions: The application of HMV helped reduce respiratory morbidity in children with childhood-onset hereditary NMD. Patients with SMA type I can benefit from an early diagnosis and the timely application of HMV. The choice between invasive and noninvasive HMV should be based on the patient's age and NIV trial tolerance. Systematic follow-up guidelines provided by a multidisciplinary team are needed.
