Insights
Children with spinal muscular atrophy (SMA) and pneumonia face extubation failure if they cannot eat independently or do not receive airway clearance therapy. Improving these factors can increase extubation success rates in pediatric patients.
Area of Science:
- Pediatric Pulmonology
- Neuromuscular Disorders
- Critical Care Medicine
Background:
- Spinal muscular atrophy (SMA) is a genetic neuromuscular disorder affecting motor neurons.
- Pneumonia is a common complication in children with SMA, often necessitating mechanical ventilation.
- Tracheal extubation failure in these vulnerable children can lead to prolonged ventilation and increased morbidity.
Purpose of the Study:
- To identify independent risk factors for tracheal extubation failure in pediatric patients with SMA and pneumonia.
- To provide evidence-based recommendations for improving extubation success in this population.
Main Methods:
- Retrospective analysis of clinical data from 34 children with SMA and pneumonia.
- Comparison of clinical characteristics between successful and failed extubation groups using Mann-Whitney U test, Chi-square test, and multivariate Logistic regression.
- Identification of independent risk factors associated with extubation failure.
Main Results:
- Multivariate analysis identified inability to eat independently before intubation (OR=39.88) and lack of airway clearance therapy (OR=14.55) as independent risk factors for extubation failure.
- The failure group exhibited higher arterial carbon dioxide levels and a greater rate of pulmonary consolidation before extubation.
- 31 out of 34 children had Type 1 SMA, indicating a severely affected cohort.
Conclusions:
- Independent risk factors for extubation failure in children with SMA and pneumonia include impaired ability to eat and absence of airway clearance techniques.
- Strategies to improve extubation success should focus on ensuring independent eating ability, implementing airway clearance, and optimizing pulmonary status.
- Early and consistent airway clearance therapy is crucial for managing respiratory complications in pediatric SMA patients.
Abstract:
Objective: To summarize the risk factors of tracheal extubation failure in children with spinal muscular atrophy (SMA) combined with pneumonia. Methods: In this retrospective study, clinical data of 34 children with SMA combined with pneumonia who were hospitalized in Children's Hospital Affiliated to Capital Institute of Pediatrics from August 2018 to December 2021 were analyzed. According to whether the extubation was successful or not, they were divided into the success group and the failure group. The risk factors that may affect the success of extubation between two groups were derived by comparing the clinical characteristics by Mann-Whitney U test and Chi-square test, followed by multivariate Logistic regression. Results: Among the 34 cases, there were 14 males and 20 females, aged 10.8 (6.0,25.2) months at the time of hospitalization, 31 cases were type 1 SMA and 3 cases were type 2. Eleven children were unable to eat independently before intubation, 22 were treated with airway clearance techniques and 28 had multiple pulmonary infections. There were 21 cases in the success group and 13 cases in the failure group. The failure group had higher maximum partial pressure of arterial carbon dioxide level during intubation and higher rate of consolidation changes in chest images before extubation (81 (49,86) vs. 48 (43,56) mmHg (1 mmHg=0.133 kPa), 6/13 vs. 10%(2/21), Z=-2.55, χ2=5.99, both P<0.05). Multivariate Logistic regression analysis showed that tube feeding before intubation (OR =39.88, 95%CI 3.36-473.29, P=0.003) and not receiving airway clearance therapy (OR =14.55, 95%CI 1.35-156.78, P=0.027) were independent risk factors for extubation failure. Conclusions: The independent risk factors of tracheal extubation failure in children with SMA combined with pneumonia are unable to eat independently before intubation and not receiving airway clearance therapy. Therefore, the conditions to improve the success of extubation consist of having the ability to eat independently before intubation, using airway clearance techniques to improve ventilation and to make the chest images as clear as possible.
