随着《中华人民共和国个人信息保护法》《中华人民共和国数据安全法》等有关法律法规的颁布实施,电子病历数据保护引起大家的重视。快速高效识别电子病历是数据保护的第一环节,也是数据安全领域的重要研究课题之一。文章提出一种基于少样本命名实体识别技术的电子病历指纹特征提取方法,首先通过公共数据集训练编码器,获得广阔的文本特征空间;然后使用电子病历数据集微调编码器,并利用原型网络表征实体类型标签;最后通过提取电子病历特征,得到“实体类型+实体集”的指纹特征。实验结果表明,与对比模型相比,该方法在I2B2数据集上性能更优异,有效提升了对电子病历数据的隐私保护能力。

目的评价静脉输注小剂量右美托咪定联合头皮神经阻滞用于学龄前儿童开颅术后镇痛的效果。方法本研究为前瞻性、随机对照双盲试验。选择首都医科大学附属北京天坛医院2022年5月至2023年12月择期行神经外科手术患儿120例, 年龄3～7岁, ASA分级Ⅰ-Ⅲ级, BMI 12～25 kg/m2。采用随机数字表法分为2组(n=60):静脉输注小剂量右美托咪定联合头皮神经阻滞组(Dex+SNB组)和单纯头皮神经阻滞组(SNB组)。Dex+SNB组经24 h静脉输注右美托咪定0.2 μg·kg-1·h-1(用生理盐水稀释至50 ml), SNB组经24 h静脉输注等容量生理盐水。术后常规使用电子静脉镇痛泵, 药物配方:舒芬太尼2 μg/kg+昂丹司琼0.3 mg/kg, 用生理盐水配至100 ml, 无背景输注, 单次给药剂量2 ml, 锁定时间30 min。采用FLACC量表评价疼痛程度, FLACC评分≥4时, 先由PACU、ICU或病房护理人员按压镇痛泵, 若无效则口服对乙酰氨基酚15 mg/kg补救镇痛。记录术后1 h内、2 h内、4 h内、18 h内、24 h内和48 h内舒芬太尼消耗量;分别于术后1、2、4、18、24和48 h时行疼痛FLACC评分、Richmond躁动-镇静评分(RASS评分)和康奈尔儿童谵妄评分(CAPD评分), 记录术后48 h内中重度疼痛(疼痛FLACC评分≥4分)、补救镇痛、镇静过度(RASS评分≤-3分)、躁动(RASS评分≥2分)、谵妄(CAPD评分>9分)和睡眠质量不佳(睡眠质量评分≤2分)的发生情况。记录术后48 h内药物相关和手术相关不良反应发生情况。结果最终SNB组纳入56例患儿, Dex+SNB组纳入55例患儿。与SNB组比较, Dex+SNB组术后2 h内、4 h内、18 h内和24 h内舒芬太尼消耗量减少, 术后18 h时疼痛FLACC评分降低, 术后第1天睡眠质量不佳发生率降低(P0.05)。结论相对于单纯头皮神经阻滞而言, 静脉输注小剂量右美托咪定联合头皮神经阻滞用于开颅手术学龄前儿童术后镇痛, 可减少阿片类药物用量, 提高睡眠质量。
