まとめ
極めて早産の乳児における早期の内ブデソニド投与は, bronchopulmonary dysplasia (BPD) のない生存率を有意に改善しなかった. この研究は,高リスクの新生児におけるBPDの予防におけるこの介入の利点は限られていることを示唆しています.
科学分野:
- 新生児医学
- 小児肺科
- 臨床試験
背景:
- Bronchopulmonary dysplasia (BPD) は,非常に早産した乳児における頻繁な合併症である.
- システミックなコルチコステロイドは BPD に有効ですが,リスクがあります.
- 肺内用コルチコステロイドは より安全な代替品です
研究 の 目的:
- 早期にブデソニドを腸内投与した時の有効性を評価する.
- 36週間の月経後のBPDフリー生存に対する影響を評価する.
- この介入の安全性を調査する.
主な方法:
- 1059人の極めて早産児 (妊娠28週未満) を対象とした二重盲検のランダム化臨床試験.
- 乳児は表面活性剤または表面活性剤単独でブデソニドを投与された.
- 主要評価項は,月経後36週に BPD のない生存でした.
主要な成果:
- BPDのない生存率は,ブデソニド投与の25.6%と,ブデソニド投与の22.6%であった (調整されたリスク差は2. 7%;95%CI,-2. 1%から7. 4%).
- 月経後36週間の全生存率は,ブデソニド投与で83. 2%,未投与で80. 6%でした.
- 生存者間でBPDの発生率が有意な差は認められなかった.
結論:
- 非常に早産の乳児のBPDのない生存に早期の内ブデソニド投与はほとんど効果を示さなかった.
- この介入が BPD の予防に有益でない可能性が示唆されています
- BPDの予防のための代替戦略を探るには,さらなる研究が必要かもしれません.

Breathing
58.5K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Inhaled Medications
237
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
222
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
232
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

Endotracheal Intubation I: Procedure
769
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
