概括

最大收缩速度 (MCV) 有效预测术后恶心和吐 (PONV). 手术前的MCV测量可以通过识别患有PONV风险的人来改善患者的康复结果.

科学领域:

麻醉学和外科手术期间的医学.
眼科医生眼科眼科
临床预测模型临床预测模型

背景情况:

手术后恶心和吐 (PONV) 是全身麻醉后的一个常见并发症.
对PONV的预测标记对于优化患者管理和康复至关重要.
动态瞳孔测量提供了一种非侵入性方法来评估自主神经系统功能.

研究的目的:

确定瞳孔光反射 (PLR) 参数,特别是动态瞳孔测量,是否可以预测PONV的发生.
为了研究术前瞳孔参数和术后恢复质量的关系.
探索PONV在瞳孔参数与康复结果之间的关联中的调解作用.

主要方法:

一项前性观察性研究,涉及在全身麻醉下进行选择性叶片切除术的患者.
在手术前使用便携式红外瞳孔计测量瞳孔参数.
在24小时内对PONV和康复质量的术后评估,使用后勤回归和ROC曲线进行分析.

主要成果:

经历PONV的患者最大瞳孔直径,平均收缩速度 (ACV),最大收缩速度 (MCV) 和百分比的瞳孔变化显着较小.
MCV 已成为 PONV 的独立预测因子, MCV 值较高与风险较低相关.
ROC分析表明,在预测PONV时,MCV具有很强的分类能力 (AUC = 0.831).

结论:

MCV是PONV的可靠和独立预测器.
PONV完全调解了MCV和术后康复质量之间的关系.
手术前的MCV测量有潜力通过早期识别PONV风险来改善患者的结果.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
