まとめ
肺内ガスのモニタリングは,肺手術後の空気漏れを検出する新しい方法を提供し,従来の水浸し試験を改善する可能性があります. 酸素のようなガスを測定することで,特に高酸素濃度を使用すると,漏れを効果的に検出できます.
科学分野:
- 胸部 外科
- 麻酔科
- 肺医学
背景:
- 水浸し試験 (W試験) は,肺切除中に空気漏れを検出するための標準ですが,微妙な漏れを見逃すことができます.
- 手術中の空気の漏れは 患者の回復と手術の結果に リスクをもたらします
研究 の 目的:
- 肺切除時に胞空気の漏れを検出するための新しい方法として胸内ガス濃度を評価する.
- 胸内ガスモニタリングの有効性を従来のWテストと比較する.
主な方法:
- 肺切除を受けた88人の患者を対象とした前向きな研究.
- デスフルラン,酸素 (O2),二酸化炭素 (CO2) の胸内濃度は,麻酔器のガス分析器を使用して測定された.
- 結果は,肺切除と修復前と後のWテスト結果と比較した.
主要な成果:
- 3つのガスの濃度の上昇は,Wテストで陽性だった31/32人の患者で観察された.
- 8人のWテストの陰性患者は高気圧を示し,再確認で陽性でした.
- 空気漏れと相関する胸内O2増加; O2なしでは漏れは検出されていません.
- W試験におけるバブル数とガス濃度 (デスフルランはr=0.84,O2はr=0.77,CO2) の間で強い正の相関が認められた.
結論:
- 胸内ガスの濃度測定は,手術中のアルベオラ空気の漏れを検出するための実行可能な代替または補完的なツールです.
- 胸内酸素のモニタリングは特に効果的であり,特に肺を再膨らませるために高濃度を使用する場合です.

Pneumothorax-II
352
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

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...

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,...

Oxygen Delivering System III: Tracheostomy and T-piece
2.3K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

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...

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....
