Analysis on efficacy of compound dextran combined with atorvastatin calcium in patients with CVS caused by SAH based on TCD blood flow indexes

Objectives: To analyze the effects of compound dextran combined with atorvastatin calcium on blood flow indexes, peroxidase 2 (Prx2) and endothelin-1 (ET-1) in patients with cerebral vasospasm (CVS) caused by subarachnoid hemorrhage (SAH).

Methods: One hundred patients with CVS caused by SAH treated in Baoding No.1 Central Hospital from January 2019 to December 2020 were divided into observation group and control group. The control group was treated with atorvastatin calcium tablets, while the observation group was additionally treated with compound dextran. The hospital stays, Glasgow Outcome Scale (GOS), hemoglobin (Hb) and hematocrit (Hct) levels before and five days after treatment were recorded. The hemodynamic parameters of the middle cerebral artery (MCA) and the serum levels of Prx2 and ET-1 were detected.

Results: After treatment, GOS and Hct levels in the observation group were both higher than those in the control group (P < 0.05). After treatment, the mean and peak velocities of the MCA in the observation group were significantly lower than those in the control group (P < 0.05). After treatment, the serum levels of Prx2 and ET-1 in the observation group were significantly lower compared with those in the control group (P < 0.05). However, no significant differences were found in the incidences of adverse reactions between the two groups (P > 0.05).

Conclusions: Compound dextran combined with atorvastatin calcium can effectively enhance clinical efficacy, improve cerebral blood flow and reduce serum Prx2 and ET-1 levels in patients with CVS caused by SAH.
