Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.7K
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...

Ultrasonography

8.2K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Ultrasound I: Abdominal Ultrasonography

2.1K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Assessment of the Abdomen III: Palpation

4.1K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Area of Science:

  • Obstetrics and Gynecology
  • Biomedical Engineering
  • Medical Imaging

Background:

  • The uterine cervix maintains pregnancy by remaining long and firm, with a closed internal os.
  • Cervical mechanical properties change during pregnancy, a process known as ripening, effacement, and dilation.
  • Traditional assessment of cervical ripening includes the Bishop score and ultrasound, but manual consistency assessment is subjective.

Purpose of the Study:

  • To explore the application of elastography in assessing cervical consistency during pregnancy.
  • To evaluate elastography as a tool for predicting pregnancy outcomes like preterm delivery and labor induction success.
  • To highlight the potential of objective elastographic methods for improved pregnancy management.

Main Methods:

  • Elastography, a technique measuring tissue deformation under pressure, was used to assess cervical properties.
  • Both static (measuring displacement) and dynamic (measuring shear wave speed) elastography methods were considered.
  • Focus was placed on assessing the stiffness of the internal os, a parameter not manually measurable.

Main Results:

  • Elastography provides information on internal os stiffness, which is crucial for pregnancy management.
  • Internal os stiffness, assessed via elastography, correlates with pregnancy outcomes.
  • This parameter is a strong predictor of preterm delivery and successful labor induction.

Conclusions:

  • Elastography is a promising diagnostic option for objective assessment of cervical mechanical properties.
  • Further research is needed to establish a consensus on the optimal elastographic method for uterine cervix assessment.
  • Identifying the most effective elastographic method could lead to novel tools for preventing adverse pregnancy events.
