Summary
Increased intracranial pressure (ICP) is likely linked to mastoid effusions (ME), a condition often seen after brain surgery. This study found a significant association between higher ICP levels and the development of ME.
Area of Science:
- Neurosurgery
- Otolaryngology
- Critical Care Medicine
Background:
- Mastoid effusions (ME) are common findings in patients post-intracranial surgery.
- The relationship between intracranial pressure (ICP) and ME remains unclear.
Purpose of the Study:
- To investigate the association between increased intracranial pressure (ICP) and the occurrence of mastoid effusions (ME) in patients undergoing intracranial surgery.
Main Methods:
- A prospective study enrolled 115 patients with ICP monitoring catheters between January 2015 and October 2018.
- Hourly ICP data and clinical factors were collected; ME was identified via imaging.
- Univariate and multivariable logistic regression analyses were used to assess predictors of ME.
Main Results:
- 61% of patients developed ME, with 94% showing ipsilateral effusion in unilateral brain lesions.
- Higher mean and peak ICP, age, trauma, CRP, ICU stay, mechanical ventilation, ETT, and NGT were associated with ME.
- ICP variables significantly improved ME prediction in multivariable analysis.
Conclusions:
- Increased intracranial pressure (ICP) is a probable contributing factor to mastoid effusions (ME).
- Further research is required to elucidate the mechanistic link between ICP and middle ear pressure.

3.3K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.

1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:24Pressure Relationships in Thoracic Cavity
5.1K
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

01:19Cranial and Spinal Meninges
3.1K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:19Veins of Head and Neck
4.5K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
