干预措施:

Interventions:

组别:

预防性万古霉素组

样本量:

54

Group:

Prophylactic Intraventricular Vancomycin group

Sample size:

干预措施:

(1)在层流洁净台内,使用不含防腐剂的生理盐水将万古霉素粉末稀释至终浓度2.5 mg/mL,用无菌注射器抽取4ml,贴标签但不标注药物名称,由专人保管;(2)封管操作:每次脑室内化疗药物输注完毕后,通过Ommaya储液囊以注射泵匀速注入4ml封管液(万古霉素)。

干预措施代码:

Intervention:

(1) Preparation of Lock Solution: Under a laminar airflow hood, preservative-free normal saline is used to dilute vancomycin powder to a final concentration of 2.5 mg/mL. A 4 mL aliquot is drawn into a sterile syringe, labeled with non-drug-specific information, and stored under designated supervision. (2) Lock Procedure: After each intraventricular chemotherapy infusion, 4 mL of the lock solution (vancomycin) is administered into the Ommaya reservoir at a constant rate via an infusion pump.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

所有研究数据,均在资格评估阶段采集并随即进行假名化处理,之后录入符合安全规范的REDCap数据库。为确保录入准确性,纸质评估表均由两名数据管理员独立执行背对背双录入,并由第三方完成一致性比对与原始记录核查。数据库内置逻辑与范围核查程序,定期自动运行以生成疑问报告,并指派专人溯源核查与修正。在数据归档阶段,由主要研究者、统计学家和数据管理员共同审核并确认数据无误后予以最终锁定,关联清单与知情同意书按规定保存十年后销毁,以实现数据完全匿名化。访问权限方面,数据库实行分级管理,全体研究作者可访问最终数据集,所有参与者排除、退出及不良事件信息均实时记录于系统。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All research data, including virtual reality test results, questionnaires, and functional assessments, were collected during the eligibility evaluation phase and immediately pseudonymized before entry into the secure REDCap database. To ensure data entry accuracy, paper-based evaluation forms were independently double-entered by two data managers in a back-to-back manner, with a third party performing consistency checks and verification against original records. The database was equipped with built-in logic and range validation procedures, which were routinely run to generate query reports. Designated personnel were assigned to trace and resolve any discrepancies. During the data archiving phase, the principal investigator, statistician, and data managers jointly reviewed and confirmed the data accuracy before final locking. Associated documentation and informed consent forms were retained for ten years as required and subsequently destroyed to achieve complete data anonymization. In terms of access permissions, the database implemented a tiered access control system. All study authors had access to the final dataset, while all participant exclusions, withdrawals, and adverse events were recorded in real time within the system.
