Ultrasonographic Measurement of Diaphragmatic Thickness in Adolescents

Status Recruiting

Clinical Trial Summary

Pectus deformities are among the most common anterior chest wall pathologies. Pectus excavatum is the most common chest deformity with an incidence of 0.1-0.3%. In severe deformities, a decrease in lung volume is observed. This can cause decreased pulmonary function and affect the function of the right ventricle. The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. So, investigators aimed to measure diaphragmatic thickness in adolescents with pectus deformity and to show whether diaphragmatic thickness is an early predictor of respiratory disorder in participants who do not show any clinical symptoms or whose respiratory functions are normal.

Clinical Trial Description

Pectus deformities are among the most common anterior chest wall pathologies. Pectus excavatum is the most common chest deformity with an incidence of 0.1-0.3%. It is more common in boys than girls at a ratio of 4:1. This deformity involves the lower part of the body of the sternum; The chest wall has shifted posteriorly. Pectus excavatum is a cosmetic defect that in most cases does not have physiological consequences. In severe deformities, a decrease in lung volume is observed. This can cause decreased pulmonary function and affect the function of the right ventricle. Funnel chest defects can cause chest pain, shortness of breath, decreased cardiac output, and decreased exercise capacity, depending on the depth of the deformity. The alignment of the skeletal system in the chest and its harmony with the compliance of the chest wall are related to respiratory function; changes in the rib cage lead to a decrease in lung capacity. The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. In recent years, ultrasonography (USG) has gained increasing utility for visualizing the diaphragm and assessing its function, with several advantages. Based on this, investigators aimed to measure diaphragmatic thickness in adolescents with pectus deformity and to show whether diaphragmatic thickness is an early predictor of respiratory disorder in participants who do not show any clinical symptoms or whose respiratory functions are normal. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
