まとめ
食道切除術後の術後の肺合併症 (PPC) は,特定の呼吸環境と関連しています. プラトウ圧力,ドライビング圧力,および1肺および2肺換気中の呼吸速度は,PPCリスクに影響を与える重要な要因です.
科学分野:
- アネステシオロジー アネステシオロジー
- 胸腔外科手術について
- クリティカルケア・メディシン
背景:
- 手術後の肺合併症 (PPC) は,食道切除術後の重大なリスクです.
- PPCに関連した手術中の要因を特定することは,患者のアウトカムにとって極めて重要です.
研究 の 目的:
- 一肺換気 (OLV) と二肺換気 (TLV) の間,PPCに関連した手術内換気パラメータを決定する.
- 換気戦略に基づくPPCの予測モデルを確立する.
主な方法:
- 選択性食道切除術を受けた454人の患者の遡及的なコホート研究.
- 多変数ロジスティック回帰分析により,OLVとTLVの段階でPPCの予測要因を特定します.
- プレート圧力,運転圧力,呼吸率,潮量,PEEP,機械力などの換気装置のパラメータを分析した.
主要な成果:
- PPCは患者の42.7%で発生しました.
- プレートプレッシャー (Pplat) とドライビングプレッシャー (DP) は,OLVとTLVの両方で独立してPPCと関連していました.
- 呼吸率 (RR) もPPCと関連していました. TLVでは,換気期間がPPCリスクを増加させ,PEEPは保護的であった. OLVでは,高潮量 (VTe) と機械力 (MP) がPPCと関連していた.
結論:
- Pplat,RR,DPはOLVとTLVの両方で一貫してPPCと関連付けられています.
- 換気期間とPEEPは,TLVとOLVの間にPPCリスクに異なる影響を及ぼします.
- OLV中のVTeとMPのような特定のパラメータは,PPCリスクを軽減するために注意が必要です.

Factors Affecting Pulmonary Ventilation
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
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 to...

Endoscopic Studies II: Thoracocentesis
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...

Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:
Clinical Manifestations:
Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
Pneumothorax II: Pathophysiology
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
