Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
There are many causes, which can be broadly grouped into three mechanisms: primary (internal bleeding and swelling); secondary (vigorous fluid replacement as an unintended complication of resuscitative medical treatment, leading to the acute formation of ascites and a rise in intra-abdominal pressure); and recurrent (compartment syndrome that ...
The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
After up to five days of fever, patients begun to suffer damage to their blood vessels, which can cause internal bleeding, psychological symptoms such as confusion and aggression, and persistent ...
Intraocular hemorrhage is classified based on the location of the bleeding: Hyphema (in the anterior chamber) Suprachoroidal hemorrhage (SCH) is a rare complication of intraocular surgery in which blood from the ciliary arteries enters the space between the choroid and the sclera. It is potentially vision-threatening. [3] [4]
Bleeding may not be readily apparent; internal organs such as the liver, kidney and spleen may bleed into the abdominal cavity. The only apparent signs may come with blood loss. Bleeding from a bodily orifice, such as the rectum, nose, or ears may signal internal bleeding, but cannot be relied upon.
An internal bleeding require to call to emergency medical services. In the event of bleeding caused by an external source (trauma, penetrating wound), the patient is usually inclined to the injured side, so that the 'good' side can continue to function properly, without interference from the blood inside the body cavity.

A CT is an imaging technique that allows physicians to see inside the head without surgery in order to determine if there is internal bleeding or swelling in the brain. [31] Computed tomography (CT) has become the diagnostic modality of choice for head trauma due to its accuracy, reliability, safety, and wide availability.
