Objective To investigate the relationship between the cerebral circulation time and disease condition and prognosis in patients with acute subarachnoid hemorrhage. Methods DSA were performed to determine the cerebral circulation time (CCT) in 60 patients who had subarachnoid hemorrhage (SAH) within 3 days. The patients were divided into different groups according to the severity of the disease condition,patients with CSC score as 13-15 were assigned as group Ⅰ ,whose CCT was (13.45 ± 1. 89) s. Twenty two patients with GSC score as 3-12 were assigned as group Ⅱ ,whose CCT was (16.79 ± 2. 07) s. There were significant difference between the CCT of the two groups (t =3. 76,P = 0. 001). (2)Twenty-nine patients with Hunt-Hess grade as 1-2 were assigned as group 1,whose CCT was (13.06 ± 1. 83) s. Thirty one patients with Hunt-Hess grade as 3-5 were assigned as group 2, whose CCT was (15. 89 ± 2.06) s. There were significant difference between the CCT of the two groups (t = 3. 39, P =0. 003). (3) Seventeen patients with delayed ischemic damage were assigned as group A, whose CCT was (16. 84 ±1.91) s. Forty three patients without delayed ischemic damage were assigned as group B, whose CCT was (12.94 ± 1. 67) s. There were significant difference between the CCT of the two groups (t = 2. 23, P =0.025). (4)Forty-six patients with GOS score as 4-5 were assigned as group a,whose CCT was (13.07 ±1. 89)s. Fourteen patients with GSC score as 1-3 were assigned as group b,whose CCT was (17.11 ± 1. 71)s. There were significant difference between the CCT of the two groups (t = 3. 27, P = 0.008). Conclusion CCT may reflect the severity of the SAH in early onset patients and has prognostic value.

Summarize the nursing experience of 9 children with X-linked agammaglobulinemia who were first treated with subcutaneous infusion of human immunoglobulin in mainland China. Nursing points: there is no precedent in mainland China for high-dose subcutaneous infusion of human immunoglobulin, therefore, it is necessary to make sufficient preparation and care before infusion, pay attention to the observation and care of drug infusion, provide guidance on home medication, pay attention to psychological care, and ensure that patients smoothly transition from hospital medication to home medication. All 9 patients successfully completed subcutaneous injection of human immunoglobulin treatment, ensure smooth transition of patients from hospital medication to home medication. and no serious adverse reactions occurred, resulting in good results.
