説明
Dysphagia is a common sequela following stroke. Patients with subarachnoid hemorrhage (SAH) often develop atrophy of the temporal muscle, but its clinical significance remains unclear. This study aimed to investigate whether temporal muscle volume (TMV) is related to subsequent oral intake in patients with SAH and evaluate the predictors of temporal muscle atrophy.We performed a retrospective analysis of 60 SAH patients receiving enteral nutrition in the acute hospitalization phase at a single center between 2009 and 2019. The TMV was segmented automatically from computed tomography images and measured on admission and at week 2. Patients with a ≥20% TMV reduction were assigned to the atrophy group (n = 24) and those with a20% TMV reduction were included in the maintenance group (n = 36). The patients' oral intake status was assessed at week 2 using the Food Intake LEVEL Scale (grade of 7-9 considered good ingestion), and the modified Rankin scale (mRS) was used at discharge (grade of 0-2 considered good prognosis). Additional data on age, sex, body mass index, severity of SAH, and protein intake were collected on day 4.The maintenance group had significantly better oral intake and mRS scores compared to the atrophy group. TMV maintenance significantly affected oral intake at week 2 and the mRS score at discharge. Multivariable logistic regression analysis revealed that protein intake on day 4 significantly influenced the maintenance of TMV.High protein nutrition in the acute stage of SAH contributes to temporal muscle maintenance and improves oral intake.
