研究目的:

明确足月、择期剖宫产患者术后急性疼痛的发生情况,筛选术后急性疼痛的相关风险因素,基于机器学习方法构建该类患者术后急性疼痛预测模型,实现对术后急性疼痛发生风险的精准预测,为临床个体化镇痛干预提供科学依据。  

Objectives of Study:

To clarify the incidence of acute postoperative pain in full-term patients undergoing elective cesarean section, screen the relevant risk factors for acute postoperative pain, construct a prediction model for acute postoperative pain in such patients based on machine learning methods, achieve accurate prediction of the risk of acute postoperative pain, and provide a scientific basis for clinical individualized analgesic intervention.
