ABSTRACT
The aim of the study was to evaluate the performance of sniff nasal inspiratory pressure (SNIP) and MIP in individuals with spinal cord injury. We evaluated 26 patients with spinal cord injury. Mean FVC in those with tetraplegia was 52 ± 19 percent of predicted, compared with 78 ± 23 percent of predicted in those with paraplegia (p < 0.05). In contrast, the percentage of predicted SNIP was lower in those with tetraplegia than in those with paraplegia (p < 0.05). In all participants, SNIP correlated significantly with the level of the injury (r = 0.489; 95 percent CI 0.125-0.737). The impact that the greater discriminatory power of SNIP has on the diagnosis of impaired pulmonary function in spinal cord-injured patients should be investigated further.
RESUMO
O objetivo deste estudo foi verificar o desempenho da pressão inspiratória nasal durante o fungar (PInas) e da PImáx em indivíduos com lesão medular traumática. Foram avaliados 26 pacientes com lesão medular traumática. Os pacientes tetraplégicos e paraplégicos exibiram diferentes médias do percentual do previsto da CVF, respectivamente, 52 ± 19 por cento e 78 ± 23 por cento (p < 0,05). Ao contrário da PImáx, o percentual do previsto médio da PInas foi inferior nos tetraplégicos (p < 0,05) e, em todos os participantes, a correlação com o nível da lesão foi significativa (r = 0,489; IC95 por cento 0,125-0,737). O impacto do melhor discernimento da PInas no diagnóstico das alterações da função inspiratória de pacientes com lesão medular traumática merece ser aprofundado.
