まとめ
小児気管挿管中の遷延性無呼吸時間は酸素飽和度低下と関連しない。しかし、無呼吸酸素化の使用は重症患児における脱飽和リスクを著しく低下させる。
科学分野:
- 小児集中治療医学
- 気道管理
- 呼吸生理学
背景:
- 小児の気管挿管中の遷延性無呼吸期間は、酸素飽和度低下につながる可能性があります。
- 無呼吸時間の延長に関連する要因を特定することは、患者の安全にとって極めて重要です。
研究 の 目的:
- 小児気管挿管中の遷延性無呼吸時間に関連する要因を特定する。
- 無呼吸期間と酸素飽和度低下との関連を調査する。
主な方法:
- 経口気管挿管を受けた18歳未満の小児204人を対象とした前向き観察研究。
- 無呼吸時間を測定し、54秒を「長い」無呼吸時間のカットオフとした。
- 酸素飽和度低下は、ベースラインSpO2が90%超の小児でSpO2 <90%と定義した。
主要な成果:
- メディアン無呼吸時間は54秒でした。乳児では無呼吸時間が長くなる傾向がありました。無呼吸時間は、気道確保困難の既往、実施医、喉頭鏡の種類によって差はありませんでした。酸素飽和度低下率は、短時間無呼吸群と長時間無呼吸群で同様でした。無呼吸酸素化は脱飽和リスクを低下させました。
結論:
- 患者の年齢は、気管挿管中の無呼吸時間の長さと関連していました。
- 無呼吸時間の長さは、酸素飽和度低下とは独立して関連していませんでした。
- 無呼吸酸素化の使用は、酸素飽和度低下の発生率低下と有意に関連しており、その日常的な使用を支持するものです。

Endotracheal Tube Extubation
3.6K
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

Endotracheal Intubation II: Nursing Management
2.4K
Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Endotracheal Intubation I: Procedure

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...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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...

Respiratory Volumes and Capacities I
1.6K
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
