概括
新的自回归框架可以准确地预测在输注醇时麻醉的深度 (DOA). 这些模型,循环内自回归 (ILAR) 和实时自回归 (RTAR),比传统方法提高了预测准确性.
科学领域:
- 麻醉学 麻醉学
- 机器学习在医学中的应用
- 制药指标 (Pharmacometrics) 是一个指标.
背景情况:
- 准确的麻醉深度 (DOA) 预测对于在全静脉麻醉期间安全输注普罗福尔至关重要.
- 传统的药理动力学 (PK) 和药理动力学 (PD) 模型往往缺乏实时DOA预测所需的精度.
- 机器学习 (ML) 模型通过匹配临床数据来提高DOA预测的准确性.
研究的目的:
- 探索实时信息对DOA预测的优势.
- 提出和评估新的自回归 (AR) 框架,以提高在麻醉诱导过程中DOA预测的准确性.
- 通过更准确的DOA预测,提高普罗波福尔剂量调整的精度.
主要方法:
- 两个自动回归框架,循环内自动回归 (ILAR) 和实时自动回归 (RTAR) 被开发和实施了注意力机制.
- 这些模型使用528名接受麻醉诱导的患者的数据进行了训练和验证,其中80%用于训练,20%用于验证.
- 使用绝对中位性能误差 (MDAPE),中位性能误差 (MDPE) 和根平均平方误差 (RMSE) 评估性能,与传统的前 (LSTM-MLP) 框架相比较.
主要成果:
- 拟议的ILAR和RTAR框架在预测麻醉诱导期间的DOA方面明显优于LSTM-MLP框架.
- ILAR和RTAR的MDAPE值分别为2.5%和11.6%,而LSTM-MLP的MDAPE值为17.7%.
- 使用实时双光谱指数 (BIS) 值的RTAR框架实现了最低的MDAPE和RMSE,显示出卓越的性能.
结论:
- 在麻醉诱导阶段,ILAR和RTAR自回归框架提供了准确的DOA预测.
- 这些模型提供了灵活性,适用于具有或没有实时BIS监控的场景.
- 与以前的LSTM-MLP方法相比,建议的AR方法显著提高了BIS价值预测的准确性.

Parenteral Anesthetics: Overview
212
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

General Anesthesia: Overview
308
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...
