まとめ
ハイパーアンギュレートビデオ喉鏡検査は,直接喉鏡検査と比較して,外科患者の内側管内挿管の試行回数を有意に減少させた. このアプローチは,手術中の呼吸道管理に好ましいかもしれません.
科学分野:
- 麻酔科
- 呼吸道管理
- 外科 術
背景:
- 直接喉鏡検査は手術室での 腸内管管注入の標準です
- ビデオ・ラーリンゴスコーピーは呼吸道視覚化を改善しますが,外科での挿管試行への影響は十分に確立されていません.
研究 の 目的:
- 成人手術患者におけるビデオ喉鏡検査と直接喉鏡検査による内腔管内注入の試行回数を比較する.
主な方法:
- 心臓,胸部,血管の手術を受けた成人の患者を対象としたクラスターランダム化クロスオーバー試験.
- 手術室は,毎週ランダムに,ハイパーアンギュレートビデオ喉鏡検査または直接喉鏡検査を使用して,最初の挿管を試みました.
- 8429件の手術のデータを用いて治療意図分析を行った.
主要な成果:
- ビデオ喉鏡検査では,直接喉鏡検査 (7. 6%) に比べて,挿管の試みが少なかった.
- 静脈管内検査の失敗率は,直接喉鏡検査 (4. 0%) よりもビデオ喉鏡検査 (0. 27%) で有意に低かった.
- 2つの方法では呼吸道と歯の損傷の割合は似ています.
結論:
- ハイパーアンギュレート・ビデオ・ラーリンゴスコーピーは,手術中の患者の内側管内挿管の試みと失敗の数を減少させます.
- この患者集団において,ビデオ喉鏡検査は,内側管内置のためのより効果的なアプローチであるようです.
- 更に研究が進めば,手術による呼吸道管理の好ましい方法として,ビデオ・ラーリンゴスコーピーを支持できるかもしれません.

Endotracheal Intubation I: Procedure
1.2K
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 Intubation II: Nursing Management
619
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 Tube Extubation
643
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....

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
192
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Tracheostomy: Procedure and Tubes
556
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...

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...
