Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.8K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

The Bronchial Tree01:23

The Bronchial Tree

3.5K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Acute Pharyngitis

1.5K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Chronic Pharyngitis01:23

Chronic Pharyngitis

4.6K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Common Respiratory Disorders01:31

Common Respiratory Disorders

878
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

科学分野:

  • 小児科
  • 感染症
  • 呼吸器医学

背景:

  • ウイルス性支氣管炎は 高所得国における幼児の入院の主な原因です
  • 主な病原体である呼吸器共感覚ウイルスは 症例の60~80%を占める.
  • 診断は典型的には臨床的であり,ウイルス検査の必要性を回避します.

研究 の 目的:

  • ウイルス性支氣管炎の現在の根拠に基づいた管理勧告の検討.
  • 様々な介入の有効性と適切な使用を評価する.
  • 非有益な介入治療の実施を停止するという 継続的な課題に取り組むこと

主な方法:

  • 質の高い証拠のレビューと体系的なレビュー
  • 臨床実務ガイドラインの分析
  • グルココルチコイド,支氣管拡張剤,高圧塩水,高流量療法などの特定の介入に関するデータの評価.

主要な成果:

  • 管理はサポートケア:水分補給と酸素補給にのみ焦点を当てるべきです.
  • グルココルチコイドと支氣管拡張剤の効果は示されていない.
  • ハイパルトニクス塩溶液はさらなる証拠を必要とし,高流量治療は低酸素の乳児の救済に限定され,ICU入院や挿管率を低下させません.

結論:

  • ウイルスの気管支炎に対する サポートケアのみのアプローチを 強く支持する証拠があります
  • ガイドラインにもかかわらず,介入療法はまだ広く使用されており,実施の大きな課題となっています.
  • 効果のない治療の廃止に重点を置くことは 最適な患者のケアに不可欠です
