Final answer:
Thoracentesis, also known as thoracic paracentesis, is a medical procedure used to remove fluid or air from the thoracic cavity. It is performed under ultrasonography to ensure patient safety and is vital in both treatment and diagnosis within the field of systemic anatomy.
Step-by-step explanation:
The term that means the same as thoracentesis and thoracic paracentesis is a medical procedure used to remove fluid or air from the thoracic cavity. The thoracic cavity is the division of the anterior (ventral) cavity that houses vital organs such as the heart, lungs, esophagus, and trachea. This procedure can be necessary when excess fluid, often referred to as pleural effusion, accumulates in this cavity, or when there is air present as in the case of a pneumothorax.
Thoracentesis is generally performed under ultrasonography guidance to ensure accuracy and safety. The process involves inserting a needle through the chest wall to collect the fluid or air that is disrupting normal physiological conditions such as stable blood pressure and homeostasis. During the procedure, the patient may be asked to sit upright and remain still. Post-procedure, the patient is monitored to guarantee vital signs, such as blood pressure, remain stable.
A successful thoracentesis leads to symptom relief and helps in diagnosing the underlying cause of the effusion. It's an important tool in systemic anatomy studies and healthcare, providing insight into the workings of specific body systems.
