概括
较高的初始高压氧 (HBO) 治疗2.8 ATA (HBO18) 中央视网膜动脉封闭 (CRAO) 显示出比2.0 ATA (HBO10) 更大的视力敏度改善. 这表明HBO18可能是CRAO更有效的急性治疗方法.
科学领域:
- 眼科医生 眼科 眼科
- 高压医学的高压医学.
- 血管医学 血管医学
背景情况:
- 中央视网膜动脉封闭 (CRAO) 是一种需要及时治疗的危急情况.
- 对于急性CRAO,最佳的高压氧 (HBO) 治疗剂量仍未确定.
- 不同的HBO协议对CRAO的比较有效性以前没有被评估.
研究的目的:
- 为了比较初始2.8 ATA HBO会话 (HBO18) 与急性CRAO的2.0 ATA协议 (HBO10) 的疗效.
- 为了评估CRAO患者在不同初始HBO剂量后的短期视力敏度结果.
- 评估CRAO治疗中不同初始HBO剂量的安全性.
主要方法:
- 追溯队列研究,比较急性CRAO的HBO18和HBO10协议.
- 排除标准包括疑似炎症性动脉炎,分支视网膜动脉封闭和HBO的禁忌.
- 主要结局:24±4小时内最佳校正视敏度 (ΔBCVA) 的变化;次要结局:神经和巴罗创伤事件.
主要成果:
- 与HBO10 (中位数0.22 LogMAR,p < 0.001) 相比,HBO18组的 ΔBCVA 改善显著更大 (中位数0.62 LogMAR).
- 多变量分析表明,HBO18的使用与24小时BCVA的0.5LogMAR改善有关 (p < 0.001).
- 不良事件发生率在各组之间相似,没有严重的停药;更大的初始视力障碍和更短的时间到HBO改善了结果.
结论:
- 在2.8 ATA (HBO18) 的初始HBO治疗似乎比2.0 ATA (HBO10) 协议更有效地改善急性CRAO的短期视力敏度.

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
634
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
621
Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Gradually Varying Flow
451
Gradually varying flow (GVF) in open channels describes situations where water depth changes slowly along the channel due to factors like non-uniform bed slope, channel shape variations, or obstructions. This flow type occurs when the depth adjusts gradually to balance gravitational forces, shear forces, and energy requirements, resulting in a low rate of depth change.Characteristics of Gradually Varying FlowGVF is commonly observed in natural streams, rivers, and canals, where flow depth...

Rapidly Varying Flow
515
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists
484
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...
