まとめ
悪性呼吸道阻害の進行性非小細胞肺がん患者の約4分の1は,しばしば30日以内に治療用のブロンコスコーピーを繰り返す必要があります. これらの患者の生存結果を改善するためにさらなる研究が必要です.
科学分野:
- 肺科
- 腫瘍学
- 介入肺科
背景:
- 悪性呼吸道阻害 (MAO) は,進行した肺がんの頻繁で衰弱させる合併症です.
- 治療用の支柱管検査はMAOの管理のための重要な介入ですが,再発は繰り返し処置を必要とします.
研究 の 目的:
- 進行性非小細胞肺がん (NSCLC) のMAO患者における再治療性ブロンコスコピーのパターンを調査する.
- 繰り返される処置に関連する要因を特定し,これらの処置後の全生存期 (OS) を分析する.
主な方法:
- 進行したNSCLCとMAOの66歳以上の患者のSEER- Medicare関連データベース (2006年−2019年) の遡及コホート分析.
- 治療用ブロンコスコピー (エンドルミナル療法,呼吸道ステント,PDT) を受けている患者を特定し,手術の繰り返しパターンとOSを調査した.
主要な成果:
- 1,092人の患者のうち,25. 4%が1年以内に再処置を必要とし,74. 4%が最初の処置から30日以内に発生しました.
- エンドルミナル治療は,最も一般的な初期治療 (71. 8%) と再治療 (85. 8%) でした.
- 2006年の31.1%から2017年の19.8%に減少した. 平均寿命は4. 5ヶ月でした.
結論:
- MAOの進行したNSCLC患者の有意な割合は,主に30日以内に,治療用のブロンコスコピーを繰り返します.
- この患者群の治療戦略を最適化するために,生存結果のさらなる調査が必要である.

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
77
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Trachea
2.7K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...
