まとめ
高流量鼻カヌーラ (HFNC) は,従来の鼻カヌーラ (NC) と比較して,エンドブロンキアル超音波 (EBUS) 誘導トランスブロンキアル針吸入 (TBNA) 中の低血圧現象を著しく減少させた. HFNCは手術中の患者の快適さも改善しました.
科学分野:
- 肺科
- 呼吸器のケア
- 医療機器
背景:
- 酸素不飽和は,意識的な鎮静下での,内支管超音波 (EBUS) 誘導トランス支管針吸入 (TBNA) 時に一般的です.
- 通常の鼻カヌーラ (NC) による酸素供給は,これらの処置中に低酸素症を予防するのに不十分かもしれません.
研究 の 目的:
- EBUS- TBNA中の酸素不飽和を防ぐために,高流量鼻カヌラ (HFNC) とNCの有効性を比較する.
- EBUS-TBNAの患者快適性に対するHFNCの影響を評価する.
主な方法:
- EBUS-TBNAを受けた300人の成人を対象としたランダム化試験です.
- 被験者はHFNCまたはNCで酸素を受けることを割り当てられました.
- 主要アウトカム:酸素不飽和 (SpO2 < 90% ≥30秒) の被験者の割合 二次的アウトカム: 脱飽和事件の数と患者の快適さ (VAS).
主要な成果:
- HFNCの使用は,低血量エピソードを経験した被験者の割合を大幅に低下させた (20% 対 42. 7%, P < 0. 0001).
- HFNCグループでは不飽和が少なく,患者の快適性が向上した (VASスコア差は7. 1mm).
- 合併症率の有意な違いは観察されなかった.
結論:
- HFNCは,EBUS- TBNAにおける臨床的に有意な低酸素症の減少において,NCよりも優れている.
- HFNCは患者の快適さを向上させ,この環境で不飽和現象の頻度を下げます.
- HFNCは,EBUS-TBNAの手順の従来の酸素療法に価値ある代替品です.

Administering Oxygen by Nasal Cannula
1.0K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Oxygen Delivering System I: Nasal Cannula and Face Mask
582
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

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...

Assessment of Diffusion and Perfusion
1.1K
Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
951
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Endoscopic Studies II: Thoracocentesis
495
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
