概括
在全身麻醉后的老年患者中,术后嗅觉衰退发生在20.4%的患者中. 手术前时钟绘图测试 (CDT) 的表现不佳与这种下降的更高发病率有关.
科学领域:
- 老年医学 老年医学
- 麻醉学 麻醉学
- 神经科学是一个神经科学.
背景情况:
- 嗅觉衰退与衰老和认知障碍有关.
- 全身麻醉可能会影响嗅觉,但发病率和原因未得到充分研究.
- 这项试点研究调查了老年人手术后即时的嗅觉功能.
研究的目的:
- 为了确定在接受非心脏手术的老年患者中立即术后嗅觉衰退的发生率.
- 探索通过时钟绘图测试 (CDT) 评估的术前认知功能与术后嗅觉变化之间的关联.
主要方法:
- 一项前性观察试点研究包括65岁以上的患者,这些患者计划在sevoflurane麻醉下进行选择性非心脏手术.
- 嗅觉功能的评估是使用Sniffin' Sticks12项识别测试进行的,分别在术前和术后16-26小时.
- 术后衰退被定义为嗅觉评分至少1个标准偏差的减少;CDT的性能在术前被记录下来.
主要成果:
- 总共有93名患者被纳入;19名 (20.4%) 经历了术后嗅觉的下降.
- 嗅觉衰退的发生率在CDT得分低 (≤5/8) (32.4%) 的患者中明显高于CDT得分高 (≥6/8) (13.6%) 的患者.
- 手术前的CDT得分仍然与手术后的立即嗅觉识别下降独立相关 (OR 0.67,P=0.022).
结论:
- 术后立即的嗅觉衰退影响了超过20%的老年手术患者.
- 术前的认知状态,如CDT表现所示,是术后嗅觉功能障碍的重要预测因素.
- 需要进一步的研究来阐明麻醉诱导的嗅觉变化的生理病理学和长期影响.

Olfaction
44.4K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Olfactory Receptors: Location and Structure
9.3K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
