Summary
After lung lobectomy, emphysematous changes significantly increased in the remaining lung on the operated side. Respiratory function, measured by forced expiratory volume in one second (FEV1.0%), did not show significant changes post-surgery.
Area of Science:
- Pulmonary Medicine
- Thoracic Surgery
- Radiology
Context:
- Lung lobectomy is a common surgical procedure for various lung conditions.
- Post-operative changes in the remaining lung parenchyma after lobectomy require careful monitoring.
- Quantitative computed tomography (CT) and pulmonary function tests are crucial for assessing lung health.
Purpose:
- To quantitatively assess the progression of emphysematous changes in the remaining lung after lobectomy.
- To evaluate the impact of lobectomy on the contralateral lung.
- To correlate changes in emphysema with respiratory function tests, specifically percent forced expiratory volume in one second (FEV1.0%).
Summary:
- This study analyzed 14 patients who underwent lung lobectomy, using high-resolution CT scans and pulmonary function tests before and after surgery.
- Results indicated a significant increase in emphysema in the remaining lung on the operated side (p=0.02) but no significant change in the contralateral lung (p=0.25).
- Percent forced expiratory volume in one second (FEV1.0%) showed no significant change post-operation (p=0.60), despite the observed increase in emphysema.
Impact:
- Highlights the need to monitor emphysema progression in the remaining lung tissue after lobectomy.
- Suggests that increased emphysema in the remaining lung may not immediately impact overall FEV1.0%.
- Informs surgical and clinical management strategies for patients undergoing lung lobectomy, emphasizing long-term pulmonary health assessment.

01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:27Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

01:10Atelectasis II: Pathophysiology
Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

01:27Pneumothorax-II
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.

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...
