Analgesic efficacy of iliopsoas plane block

Type:

Primary indicator

测量时间点:

阻滞后20分钟(T1)

测量方法:

阻滞后20分钟患肢活动时VAS评分<4分判定为镇痛有效,否则判定为镇痛无效

Measure time point of outcome:

20 minutes after block (T1)

Measure method:

Analgesia was considered effective if the visual analogue scale (VAS) score during limb movement was <4 at 20 minutes after block; otherwise, it was considered ineffective.

指标类型:

副作用指标

Outcome:

Adverse events related to iliopsoas plane block

Type:

Adverse events

测量时间点:

阻滞实施后至阻滞后手术结束

测量方法:

记录阻滞实施后是否出现不良反应,包括但不限于: ① 局麻药相关不良反应(如头晕、耳鸣、口周麻木、心悸等); ② 穿刺相关并发症(如局部血肿、穿刺部位疼痛); ③ 其他需临床干预的不良事件。 以发生例数和发生率进行描述性统计。

Measure time point of outcome:

From completion of block to the end of surgery

Measure method:

The occurrence of adverse events after block performance is recorded, including but not limited to: (1) local anesthetic–related adverse reactions (e.g., dizziness, tinnitus, perioral numbness, palpitations); (2) puncture-related complications (e.g., local hematoma, puncture site pain); (3) other adverse events requiring clinical intervention. The number and incidence of adverse events are summarized descriptively.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用 Dixon 上下序贯法(up-and-down sequential method)进行剂量探索研究,不采用传统随机分组方法。首例受试者给定预设初始剂量,后续受试者的给药容量根据前一例患者的镇痛效果(有效或无效)进行递增或递减调整,因此未生成随机序列。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study uses the Dixon up-and-down sequential method for dose-finding and does not apply conventional randomization. The dose administered to each subsequent participant is adjusted according to the analgesic response (effective or ineffective) of the previous participant; therefore, no random sequence is generated.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

本研究未对操作者实施盲法,但镇痛效果评估由未参与阻滞操作的研究人员完成,实施评估者盲法。

Blinding:

The anesthesiologist performing the block was not blinded. However, analgesic outcomes were assessed by an investigator who was not involved in the block procedure, and assessor blinding was applied.

是否共享原始数据:

IPD sharing

否No

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Individual participant data will not be shared publicly. The study data are used solely for the purposes of this research and involve participant privacy and ethical considerations. Aggregated data may be made available upon reasonable request to the corresponding author after study completion, subject to approval by the ethics committee and under strict confidentiality.

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:

本研究采用病例报告表(Case Record Form,CRF)进行数据采集。所有研究数据由研究人员在统一设计的纸质CRF表中填写,包括一般资料、阻滞相关信息、疼痛评分及不良事件等。数据录入由两名研究人员分别进行并相互核对,发现不一致时由第三方研究人员核查原始资料并予以更正。所有数据匿名化处理,仅使用研究编号进行标识,研究资料由专人负责保管,仅限研究团队成员使用。研究结束后,数据采用SPSS统计软件进行分析。

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

Data are collected using standardized case report forms (CRFs). All study-related information, including demographic data, block-related parameters, pain scores, and adverse events, is recorded on paper-based CRFs. Data entry is performed independently by two investigators and cross-checked for accuracy. Any discrepancies are resolved by verification against the original source documents. All data are anonymized and identified only by study codes. Access to the data is restricted to study investigators. Statistical analysis is performed using SPSS software after completion of data collection.
