研究目的: |
围术期神经认知功能障碍Perioperative Neurocognitive Disorders, PND)是指在围术期内发生的包括术后谵妄(Postoperative Delirium, POD)、延迟性认知功能恢复(Delayed Neuroconnitive Recovery,dNCR)和术后认知功能障碍(Postoperative Cognitive Dysfunction, POCD)。PND在老年患者中较为常见,也是麻醉、精神、老年等各个专科共同关注的热点;在老年人中的患病率从5%-55%不等,会导致许多不良结果,包括包括住院时间延长、身体功能和生活质量下降以及残疾和死亡率增加。其中POD通常表现为急性、波动性意识模糊,患者在术后一周内或者出院前表现出症状,随着全球老龄化的加剧,POD已成为外科手术患者的重要并发症之一。现有研究提示老年骨科患者发生POD的几率较高,13%-50%不等,特别是髋部骨折、关节置换手术及脊柱手术等。此外骨科手术往往涉及较大的创伤及长时间的术后康复过程,并且老年骨科患者往往合并多种疾病如高血压、冠心病、糖尿病等,这些都是发生POD的高危因素。同时老年骨科患者的术后康复往往依赖认知功能,因此本研究希望能针对该人群,能够有效识别POD的高危因素,为开发个性化的围术期管理策略提供科学依据,并为术后康复的改善提供实用指导。 |

Objectives of Study: |
Perioperative neurocognitive disorders (PND) refer to cognitive impairments occurring during the perioperative period, encompassing postoperative delirium (POD), delayed neurocognitive recovery (dNCR), and postoperative cognitive dysfunction (POCD). PND is relatively common in elderly patients and has become a key focus across anesthesiology, psychiatry, geriatrics, and other specialties. The prevalence of PND among older adults ranges from 5% to 55%, leading to numerous adverse outcomes, including prolonged hospitalization, decreased physical function and quality of life, as well as increased disability and mortality rates. POD is typically characterized by an acute and fluctuating disturbance of consciousness, with symptoms manifesting within one week postoperatively or before hospital discharge. With the intensification of global population aging, POD has become one of the most significant complications in surgical patients. Current studies indicate that elderly orthopedic patients have a particularly high incidence of POD, ranging from 13% to 50%, especially following procedures such as hip fracture repair, joint replacement, and spinal surgery. Orthopedic surgery often involves substantial trauma and prolonged postoperative rehabilitation, and elderly orthopedic patients frequently have multiple comorbidities such as hypertension, coronary heart disease, and diabetes, all of which are risk factors for POD. Moreover, postoperative recovery in elderly orthopedic patients often depends on cognitive function. Therefore, this study aims to effectively identify high-risk factors for POD in this population, provide a scientific basis for developing personalized perioperative management strategies, and offer practical guidance to improve postoperative recovery. |

随机方法(请说明由何人用什么方法产生随机序列): |
由独立的统计人员采用计算机随机数表(例如SPSS软件、Excel、Randomization.com、R软件等)生成随机序列。分组分配通过密封、连续编号的不透明信封保证分配隐藏 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Randomization was performed by an independent statistician using a computer-generated random number sequence. The random sequence was generated with the use of [for example: SPSS software version XX / Microsoft Excel / Randomization.com / R software, etc.]. Allocation concealment was ensured by using sealed, opaque, and sequentially numbered envelopes |

盲法: |
本研究采用单盲设计,盲法对象为广西医科大学第二附属医院符合纳入条件的老年骨科手术患者。即,在整个研究过程中,这些患者对其具体分组情况不知情,而负责干预实施和结果评估的研究人员知晓分组信息。数据分析人员在数据编码后同样对分组信息保持盲态,以进一步减少研究偏倚。 |
|
Blinding: |
A single-blind design was adopted in this study. The blinding was specifically applied to the eligible elderly orthopedic surgical patients enrolled at the Second Affiliated Hospital of Guangxi Medical University. Throughout the study, these patients were unaware of their group allocation, while the investigators responsible for intervention and outcome assessment were informed of the assignments. Additionally, the data analysts remained blinded to the group allocation after data coding to further minimize bias. |
