ABSTRACT
OBJECTIVE:
Respiratory complications are the main causes of morbidity and mortality in patients with neuromuscular disease (NMD). The objectives of this study were to determine the effects that routine daily home air-stacking maneuvers have on pulmonary function in patients with spinal muscular atrophy (SMA) and in patients with congenital muscular dystrophy (CMD), as well as to identify associations between spinal deformities and the effects of the maneuvers.METHODS:
Eighteen NMD patients (ten with CMD and eight with SMA) were submitted to routine daily air-stacking maneuvers at home with manual resuscitators for four to six months, undergoing pulmonary function tests before and after that period. The pulmonary function tests included measurements of FVC; PEF; maximum insufflation capacity (MIC); and assisted and unassisted peak cough flow (APCF and UPCF, respectively) with insufflations.RESULTS:
After the use of home air-stacking maneuvers, there were improvements in the APCF and UPCF. In the patients without scoliosis, there was also a significant increase in FVC. When comparing patients with and without scoliosis, the increases in APCF and UPCF were more pronounced in those without scoliosis.CONCLUSIONS:
Routine daily air-stacking maneuvers with a manual resuscitator appear to increase UPCF and APCF in patients with NMD, especially in those without scoliosis. .RESUMO
OBJETIVO:
As complicações respiratórias são as principais causas de morbidade e mortalidade em pacientes com doenças neuromusculares (DNM). Os objetivos deste estudo foram determinar os efeitos que o treinamento diário domiciliar com manobras de empilhamento de ar tem na função respiratória de pacientes com amiotrofia espinhal (AE) e distrofia muscular congênita (DMC), e identificar possíveis associações entre deformidades na coluna vertebral e os efeitos das manobras.MÉTODOS:
Dezoito pacientes com DNM (dez com DMC e oito com AE) foram submetidos a treinamento diário domiciliar de empilhamento de ar com ressuscitador manual por um período de quatro a seis meses e submetidos a testes de função pulmonar antes e após tal período. Os testes de função pulmonar incluíram medidas de CVF, PFE, a capacidade de insuflação máxima (CIM) e a medida do pico de fluxo de tosse não assistido e assistido (PFTNA e PFTASS, respectivamente).RESULTADOS:
Após o uso das manobras de empilhamento de ar no domicílio, houve uma melhora significativa na PFTNA e PFTASS. Nos pacientes sem escoliose, houve também um aumento significativo na CVF. No grupo de pacientes sem escoliose, o ganho na PFTNA e PFTASS foi superior ao do grupo com escoliose.CONCLUSÕES:
A utilização rotineira diária de manobras de empilhamento de ar com ressuscitador manual parece melhorar a PFTNA e PFTASS em pacientes com DNM, especialmente naqueles sem escoliose. .
