Study phase:

研究设计:

横断面 

Study design:

Cross-sectional 

研究目的:

(1)横断面调查非局麻手术患者术后24小时内急性中重度疼痛的发生率及疼痛强度分布。 (2)基于收集的围术期数据,采用单因素及多因素分析方法,筛选术后发生急性中重度疼痛的独立风险因素。 (3)利用机器学习算法,训练并优化预测模型,并通过内部验证评估其区分度、校准度及临床实用性。 (4)初步开发融合时序依赖性和复杂决策空间的个性化镇痛方案推荐模型。  

Objectives of Study:

(1) Conduct a cross-sectional survey to assess the incidence and intensity distribution of acute moderate-to-severe pain within 24 hours after surgery in patients undergoing non-local anesthesia. (2) Based on the collected perioperative data, use univariate and multivariate analysis methods to identify independent risk factors for postoperative acute moderate-to-severe pain. (3) Use machine learning algorithms to train and optimize predictive models, and evaluate their discrimination, calibration, and clinical utility through internal validation. (4) Initially develop a personalized analgesic recommendation model that integrates temporal dependencies and complex decision-making spaces.
