High protein intake after subarachnoid hemorrhage improves oral intake and temporal muscle volume.

BACKGROUND & AIMS: 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. METHODS: 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 a <20% 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. RESULTS: 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. CONCLUSIONS: High protein nutrition in the acute stage of SAH contributes to temporal muscle maintenance and improves oral intake.

Enteral nutrition increases interstitial brain glucose levels in poor-grade subarachnoid hemorrhage patients.

Low brain tissue glucose levels after acute brain injury are associated with poor outcome. Whether enteral nutrition (EN) reliably increases cerebral glucose levels remains unclear. In this retrospective analysis of prospectively collected observational data, we investigate the effect of EN on brain metabolism in 17 poor-grade subarachnoid hemorrhage (SAH) patients undergoing cerebral microdialysis (CMD) monitoring. CMD-values were obtained hourly. A nutritional intervention was defined as the clinical routine administration of EN without supplemental parenteral nutrition. Sixty-three interventions were analyzed. The mean amount of EN per intervention was 472.4 ± 10.7 kcal. CMD-glucose levels significantly increased from 1.59 ± 0.13 mmol/l at baseline to a maximum of 2.03 ± 0.2 mmol/l after 5 h (p < 0.001), independently of insulin-treatment, baseline serum glucose, baseline brain metabolic distress (CMD-lactate-to-pyruvate-ratio (LPR) > 40) and the microdialysis probe location. The increase in CMD-glucose was directly dependent on the magnitude of increase of serum glucose levels (p = 0.007). No change in CMD-lactate, CMD-pyruvate, CMD-LPR, or CMD-glutamate (p > 0.4) was observed. Routine EN also increased CMD-glucose even if baseline concentrations were critically low ( < 0.7 mmol/l, neuroglucopenia; p < 0.001). These results may have treatment implications regarding glucose management of poor-grade aneurysmal SAH patients.

Cilostazol administration with combination enteral and parenteral nutrition therapy remarkably improves outcome after subarachnoid hemorrhage.

OBJECTIVE: In order to prevent cerebral vasospasm (VS) following aneurysmal subarachnoid hemorrhage (SAH), we introduced combined enteral nutrition (EN) and parenteral nutrition (PN) with oral cilostazol administration to the postoperative patient after SAH and investigated the effect on VS. METHODS: After aneurysmal SAH, 130 postoperative patients were enrolled in this study between April 2008 and March 2012. The patients enrolled before April 2010 were treated by conventional therapy (control group). The patients enrolled after April 2010 were administrated cilostazol 200 mg/day and received EN and PN simultaneously (combined group). RESULTS: The combined group consisted of 62 patients and the control group of 68 patients. Angiographic VS occurred in 33.9 % (n = 21) of the combined group and in 51.5 % (n = 35) of the control group (p = 0.051, Fisher exact test). The incidence of symptomatic VS was significantly lower in the combined group (p = 0.001). The incidence of new cerebral infarctions was also significantly lower in the combined group (p = 0.0006). Clinical outcome at discharge was also significantly better in the combined group than in control group (p = 0.031). CONCLUSIONS: Cilostazol administration with combination EN and PN is remarkably effective in preventing cerebral VS after aneurysmal SAH.

Successful enteral nutritional support in the neurocritical care unit.

PURPOSE: Adequate caloric intake is associated with improved outcome in neurocritical illness, but factors influencing the provision of enteral nutrition (EN) have not been systematically evaluated. The primary goal of the study was to determine the EN intake of neurosurgical intensive care unit (ICU) patients within the first week of illness and investigate the factors contributing to achieving caloric goals. METHODS: A retrospective cohort of adult patients admitted to the neurosurgery service (NS) during August 2005-August 2006 were randomly selected and stratified into three groups based on their ICU-admission Glasgow Coma Scale Score (GCS) (GCS > 11, GCS 8-11, GCS 4-7). Daily EN intake, GCS, and other clinical data were collected. RESULTS: A total of 71 patients were included (GCS > 11 = 23, GCS 8-11 = 23, GCS 4-7 = 25). Admitting diagnoses included traumatic brain injury (TBI) (32%), subarachnoid hemorrhage (SAH) (32%), and intracerebral hemorrhage (17%). The overall in-hospital mortality was 23.9%. Overall, the maximum daily mean calories provided was 1,100 kcal (mean of 55% of caloric goal on hospital day 6). The median time to feeding was approximately 3 days in each group. GCS did not appear to significantly affect the mean % of caloric goal administered in patients with a minimum daily GCS < or = 11 (P = 0.053). Multivariate analysis revealed that clinical care factors, such as time to EN orders and enteral access confirmation, were significant impediments to EN provision (P = 0.001). CONCLUSION: System-based clinical care factors appear to have great impact on the successful provision of EN in the first week of neurocritical illness.
