Ultrasound and Respiratory Physiological Signals in Lung Diseases

The use of lung ultrasound is instrumental in the evaluation of many chest pathologies and its ability to detect pleuro-pulmonary pathology is widely accepted. However, the use of ultrasound to explore the state of the peripheral lung parenchyma, when the organ is still aerated, is a relatively new application. Horizontal and vertical artifacts are separate and distinct artifacts that can be seen during ultrasound examination of the lungs. While the practical role of lung ultrasound artifacts is accepted to detect and monitor many conditions, further research is needed for the physical interpretation of ultrasound artifacts. These artifacts are diagnostic signs, but we don't fully understand their origin. The artifactual information deriving from the surface acoustic interaction, beyond the pleural line, in the ultrasound images of the normally aerated and non-deflated lung, represents the final result of complex interactions of acoustic waves with a specific three-dimensional structure of the biological tissue. Thus, the umbrella term "vertical artifacts" oversimplifies many physical phenomena associated with a pathological pleural plane. There is growing evidence that vertical artifacts are caused by physiological and pathological changes in the superficial lung parenchyma. Therefore, the need emerges to explore the physical phenomena underlying the artifactual ultrasound information deriving from the surface acoustic interaction of ultrasound with the pleuro-pulmonary structures.

Perioperative Risk Factors Related to the Prognosis of Lung Transplantation: A Retrospective Study

This study analyzes patients who underwent lung transplantation at the First Affiliated Hospital of Zhejiang University from 2017 to 2024, focusing on anesthesia's impact on post-op results. It gathers patient data from hospital and Mediston systems, with main focus on in-hospital complications and secondary focus on ICU stay, post-op hospitalization, mortality, and intubation time. The research aims to deepen understanding of anesthetic management's role in lung transplant outcomes and guide improvements in perioperative anesthesia protocols.
