Impact of Hunt-Hess grade on the glycemic status of aneurysmal subarachnoid hemorrhage patients.
OBJECTIVE: This study has explored the impact of Hunt-Hess (H-H) grade of aneurysmal subarachnoid hemorrhage (aSAH) on the glycemic status of such patients during their intensive care unit (ICU) stay and has also analyzed whether H-H grade predicts their outcome independent of their glycemic status.
MATERIALS AND METHODS: This was a retrospective case record review of prospectively maintained database of 1090 previously non-diabetic aSAH patients admitted to Thomas Jefferson University Hospital, Philadelphia. H-H grade of SAH, serum and CSF glucose on admission, serum glucose on the day of surgery and 14 days post-surgery, as well as the extended Glasgow Outcome Score (GOS-E score) at discharge were noted. After univariate analysis, significant variables (P < 0.05) were entered into a logistic regression model to identify significant associations with admission H-H grade.
RESULTS: Although admission serum glucose was significantly higher for H-H grades 4-5 than grades 1-3 (P < 0.001); after postoperative day 4, the difference between the H-H grades got blurred. Admission CSF glucose was also significantly higher for H-H grades 3-4 than for grades 1-3 and 5 (P < 0.001). H-H grades 4-5 were related with higher incidences of both hypoglycemia (serum glucose level < 80 mg/dl) and hyperglycemia (serum glucose level > 200 mg/dl) (P < 0.001) during the 14-day period of ICU stay. Also, the relationship between serum and CSF glucose levels at admission increased with HH grades 1 through 4, but became negative and more tightly bound at H-H grade 5. Admission H-H grades 4-5 contributed to poor outcome compared to lower H-H grades (P < 0.0001).
CONCLUSION: Poor admission H-H grades lead to poor immediate glycemic status as well as poor short-term outcome, and it is dependent on serum glucose but independent of CSF glucose in predicting the outcome.
