概括
手术后巴罗反射灵敏度 (BRS) 的急剧下降,特别是在初始BRS高的人群中,预测术后疼痛增加. 监测术后的BSR变化 (ΔBRS) 可能有助于个性化疼痛管理策略.
科学领域:
- 心血管生理学心血管生理学
- 疼痛管理 疼痛管理
- 自主神经系统功能 自主神经系统功能
背景情况:
- 较高的腹反射灵敏度 (BRS) 通常与较低的疼痛灵敏度相关.
- 以前的研究结果表明,术前BRS升高预测心胸外科手术后术后疼痛增加,这与现有证据相矛盾.
- 这项研究研究了BRS (ΔBRS) 中的术后变化,作为术后疼痛的预测因素.
研究的目的:
- 为了确定手术前后发生的巴罗反射灵敏度变化 (ΔBRS) 是否比基线BRS更好地预测术后疼痛严重程度.
- 探索心胸外科手术后的BRS动态和疼痛之间的关系.
主要方法:
- 对72名接受选择性微创心胸外科手术的成年人进行前性观察性队列研究.
- 自发心血管BRS在手术前和手术后的第一天和第二天进行测量.
- 使用PEG尺度评估疼痛的严重程度;还测量了炎症生物标志物.
- 多变量回归模型分析了BRS指标和疼痛之间的关联,并对共变量进行调整.
主要成果:
- 术前较高的BRS与术后更大的BRS衰退 (ΔBRS) 和术后第二天更严重的疼痛有关.
- ΔBRS独立且反向与疼痛严重程度相关,即使经过对共变量进行调整.
- 炎症标志物在术后增加,但没有调解BRS与疼痛的关联.
结论:
- 显著的术后BRS下降,特别是在最初高BRS的个体中,可能表明自主失稳定和降低巴罗反射介导的疼痛抑制.
- ΔBRS成为术后疼痛的动态和机械信息预测指标.
- 经期操作的BRS监测可以帮助风险分层,并指导干预措施以稳定自主功能以改善恢复.

Neural Regulation of Blood Pressure
6.8K
The neural regulation of blood pressure involves intricate interactions between the autonomic nervous system (ANS) and cardiovascular system, ensuring adequate perfusion of tissues. This regulation primarily occurs through baroreceptor and chemoreceptor reflexes, involving both short-term and long-term mechanisms.

Analgesia and Pain Management
1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
