Measure method:

Calculate the following variables from the raw data: maximum pressure (the maximum value across all time points), pressure load = (T1 + 2T2 + T4)/4, average pressure = (T1 + T2 + T3 + T4)/4, and pressure drop = T2 - T3.

采用FLIR ONE红外热成像仪(美国FLIR公司)测量患者进入手术间时(T1)及术后30分钟时(T2)的面部皮肤表面温度,计算温度差值ΔT = T1 - T2

Measure time point of outcome:

Facial skin surface temperature upon the patient’s entry into the operating room (T1) and 30 minutes postoperatively (T2)

Measure method:

Using the FLIR ONE thermal imaging camera (FLIR Systems, Inc., USA), the surface temperature of the patient’s facial skin was measured upon entering the operating room (T1) and 30 minutes post-surgery (T2), and the temperature difference ΔT = T1 – T2 was calculated.

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:

病例记录表(Case Record Form, CRF):参照 CONSORT 指南及研究方案设计结构化纸质病例表,内容涵盖患者人口学资料、术前基线特征(BMI、糖尿病史、白蛋白水平、Braden 评分等)、手术相关信息(术式、麻醉方式、手术时长)、术中减压干预执行细节(减压频率、依从性)、主要结局指标(术后 24h 颌面部 IAPI 发生情况)、次要结局指标(术中颌面部压力、皮肤温度)及不良事件记录等核心研究变量。 电子采集和管理系统(Electronic Data Capture, EDC):本研究未使用专业互联网 EDC 平台,采用Excel 电子表格作为辅助管理工具,替代传统 EDC 系统进行数据录入、存储与质控。由两名经过统一培训的研究人员,分别独立将纸质病例表中的所有数据双录入至同一 Excel 数据库,完成录入后进行交叉核对,针对录入不一致的数据溯源至原始病例表修正;同时利用 Excel 内置的逻辑校验规则(如数值范围校验、缺失值提醒)自动识别数据错误,确保数据录入准确无误。研究全程留存纸质病例表原件与 Excel 原始数据库,可追溯至每一项数据来源,保障数据的完整性、准确性与可重复性。

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

Case Report Form (CRF): A structured paper CRF was developed in accordance with the CONSORT 2010 statement and the study protocol. The CRF covered core research variables including demographic characteristics, preoperative clinical data (BMI, history of diabetes, albumin level, Braden score), surgical parameters (surgical procedure, anesthesia method, operation duration), details of intraoperative decompression intervention (repositioning frequency, compliance), primary outcome (incidence of maxillofacial IAPI within 24 hours after surgery), secondary outcomes (intraoperative maxillofacial pressure, skin temperature), and adverse events. Electronic Data Capture & Management: To ensure data accuracy and traceability, two trained researchers independently performed double data entry of all CRF data into an Excel spreadsheet. Post-entry cross-checking was conducted to identify discrepancies, which were resolved by referring back to the original paper forms. Built-in logical validation rules in Excel (e.g., range checks for numerical data, missing value alerts) were applied to detect and correct input errors in real time. Original paper CRFs and the Excel database were retained throughout the study, ensuring full traceability of all data, integrity, and reproducibility of the research.
