概括
经历跌倒的老年人可能需要部CT扫描,如果在抗凝药,显示神经缺陷,或如果老年. 这项研究确定了与跌倒相关的头部损伤中内病理的关键预测因素.
科学领域:
- 紧急医疗 紧急医疗
- 放射学 放射学是一门学科.
- 老年病的医生 老年病的医生
背景情况:
- 老年人 (≥65岁) 的跌倒经常导致急诊室访问和轻度创伤性脑损伤.
- 内出血风险各不相同,目前的CT决策工具往往排除了老年人,导致潜在的不必要的成像.
- 识别内病理的预测因子对于针对性成像在这个人口群体中至关重要.
研究的目的:
- 在所有头部受伤的成年人中确定内病理的预测因素.
- 为了比较年长和年轻的成年患者之间的预测因素.
- 为未来对老年人的头骨成像进行前性研究的设计提供信息.
主要方法:
- 对疑似头部损伤的CT脑研究的回顾性分析 (2024年6月至8月).
- 纳入标准:年龄≥18岁且疑似头部受伤的患者;排除标准:年龄<18岁或非创伤性征兆.
- 对临床变量 (GCS,病前功能,抗凝血) 的逻辑回归分析,以评估与内病理的关联.
主要成果:
- 包括110名患者,平均年龄为73.5岁;8.2%的CT检测结果呈阳性.
- 抗凝血状态显示出与 CT 阳性发现的统计学意义上的关联 (p=0.047).
- 老年和新的神经缺陷是潜在的指标,而吐和疑似头骨骨折有较弱的关联.
结论:
- 抗凝药,老年和新的神经缺陷是老年人跌倒后内病理的潜在指标.
- 由于少数阳性病例和成像选择的队列,研究结果产生了假设.
- 结果将指导前性研究,以开发一个更安全,更有针对性的大脑成像在老年人的预测框架.

Dural hernia following spinal endoscopic surgery is a rare complication. Here, we report a case of nerve root hernia associated with the absence of dural repair, prolonged operation time, and increased abdominal pressure due to postoperative constipation. Early dural tear repair and monitoring postoperative constipation can help prevent cauda equina...
