まとめ
この研究では,静脈管内側圧力を測定するための圧力センサーを備えた静脈管 (ETT) のプロトタイプを開発した. この技術は圧力を監視し,喉の損傷を軽減し,気管切除の決定を導く可能性があることを示しています.
科学分野:
- 医療機器
- 麻酔科
- 耳鼻喉科
背景:
- 喉の損傷は,内側管内置で発生するリスクです.
- 傷害を防ぐために,後頭球の圧力を正確に測定する必要があります.
研究 の 目的:
- 背面の喉圧を測定できる内管 (ETT) のプロトタイプを開発し,評価する.
- 異なるETTサイズと喉の角度が測定された圧力に与える影響を評価する.
主な方法:
- ピエゾ電気圧力センサーを搭載した改造されたETT (6,7,8mm) が使用された.
- 喉の模様と新鮮な凍った死体で挿管を行った.
- 圧力測定は様々な下喉角 (HLA) と頭部位置で行われました.
主要な成果:
- 圧力はより急性なHLA (45°対90°) で有意に増加した.
- より大きな ETT サイズは一般的により高い圧力を及ぼしました.
- 死体研究では,ETTのサイズと頭部位置による有意な圧力差が示された (中立と屈折).
結論:
- エンドトラケア管ベースの圧力センサーは,後部喉圧を効果的に監視できます.
- この技術は喉頭損傷のリスクのある患者を特定するのに役立ちます.
- 合併症を最小限に抑えるため,早期の気管切除の決定を導く可能性.

Endotracheal Intubation I: Procedure
3.0K
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...

Endotracheal Tube Extubation
1.4K
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....

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
74
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...

Tracheostomy: Procedure and Tubes
1.1K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Suctioning the Oropharyngeal Airway
374
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
