まとめ
新生児において、胸骨への胸骨圧迫(CC)
科学分野:
- 新生児心臓学;小児蘇生;心エコー検査
背景:
- 新生児における胸骨圧迫(CC)の正確なランドマーク設定は、効果的な蘇生のために不可欠です。;CC中の新生児における左心室(LV)の正確な位置は、明確に定義されていません。
研究 の 目的:
- 新生児における左心室(LV)の解剖学的位置を決定すること。;経胸壁心エコー検査を用いて、胸骨下部領域への胸骨圧迫(CC)によって圧迫される構造を特定すること。
主な方法:
- 50人の新生児を対象とした前向き観察コホート研究。;心臓構造を可視化するために経胸壁心エコー検査を使用しました。;米国心エコー検査ガイドラインに従って標準的な心エコー検査ビューを取得しました。
主要な成果:
- 左心室(LV)は、胸骨左縁第3肋間(2%)で確認されることはまれでした。ほとんどの新生児では、LVはより外側に位置し、胸骨左縁第4(44%)、第5(50%)、または第6(4%)肋間にありました。胸骨下部1/3への胸骨圧迫は、LVを効果的に標的としない可能性があります。
結論:
- 新生児に対する現在の胸骨圧迫(CC)ガイドラインは、左心室(LV)ではなく、右心、大静脈、および大動脈を意図せず標的としている可能性があります。;新生児蘇生におけるCCの配置を最適化するためには、さらなる研究が必要です。

Gross Anatomy of the Lungs
4.3K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

The Thoracic Cage: Sternum
5.7K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

Muscles of the Thorax
3.5K
The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...

Anatomy of Respiratory System II: Lower Respiratory Tract
3.3K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Pulmonary Cycle: Exhalation
3.0K
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...

Anatomical Positions
19.2K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
