Insights
Long-term non-invasive ventilation (LT-NIV) may improve sleep-related breathing disorders in children with central nervous system (CNS) disorders. However, limited data exist on its impact on mortality and hospitalization rates in this population.
Area of Science:
- Pediatric Pulmonology
- Neurology
- Sleep Medicine
Background:
- Long-term non-invasive ventilation (LT-NIV) is a common treatment for pediatric sleep-related breathing disorders (SRBD).
- Children with central nervous system (CNS) disorders have a high prevalence of SRBDs.
- The efficacy and outcomes of LT-NIV in pediatric CNS populations are not well-established.
Purpose of the Study:
- To systematically review the existing literature on the use of LT-NIV in children with CNS disorders.
- To assess the impact of LT-NIV on mortality, hospitalization, and respiratory parameters in this specific pediatric group.
Main Methods:
- A systematic review and meta-analysis was conducted as a sub-study of a larger scoping review on LT-NIV in children.
- Studies published between January 1990 and March 2024 were included, focusing on children with CNS disorders.
- Risk of bias was assessed using the Non-Randomized Studies of Interventions tool.
Main Results:
- Fifty-five studies involving 2,015 children with CNS disorders using LT-NIV were analyzed.
- Meta-analysis showed no significant difference in mortality between children with and without CNS disorders.
- Hospitalization rates appeared higher in children with CNS disorders, and LT-NIV use demonstrated reductions in the apnea-hypopnea index, though with variable individual responses.
Conclusions:
- LT-NIV may offer benefits for pediatric patients with CNS disorders, particularly in managing SRBDs.
- Current evidence is limited, with ongoing uncertainty regarding LT-NIV's effects on mortality and hospitalization.
- Further research is needed to clarify the long-term outcomes of LT-NIV in children with CNS disorders.
Background:
Long-term non-invasive ventilation (LT-NIV) is commonly used to treat sleep-related breathing disorders (SRBD) in children. Children with central nervous system (CNS) disorders experience a high rate of SRBDs. However, the outcomes of LT-NIV use for children with CNS disorders remains unclear.
Methods:
This systematic review is a sub-study of a scoping review on LT-NIV use in children. The scoping review search strategy identified studies of children using LT-NIV from January 1990 to March 2024. These results were searched for studies of children with CNS disorders. To identify studies for meta-analysis, studies were grouped as: 1) studies of children with CNS disorders as part of broader a broader group of children using LT-NIV; 2) studies exclusively of children with CNS disorders using LT-NIV; and 3) studies of children with congenital central hypoventilation syndrome using LT-NIV. The Non-Randomized Studies of Interventions tool was used to assessed risk of bias.
Results:
A total of 55 studies met inclusion criteria and included 2,015 children with CNS disorders using LT-NIV. Nineteen studies reported outcomes specific to children with CNS disorders. Meta-analysis of four studies showed no difference in mortality between children with and without CNS disorders(1.23, 95% CI: 0.40-3.79). Hospitalization rates across four studies suggested a higher rate of hospitalization in children with CNS disorders compared to children without CNS disorders. Meta-analysis of three studies showed reductions in the apnoea-hypopnoea index following LT-NIV use; the response to LT-NIV, however, varied across individual studies.
Conclusion:
LT-NIV use may benefit some children with CNS disorders, particularly through improvements in sleep-related breathing disorders. However, data remain limited, and uncertainty persists regarding the impact on mortality, hospitalization, and other important outcomes.
