capillary hemorrhage

hemorrhage

 [hem´ŏ-rij]

the escape of blood from a ruptured vessel; it can be either external or internal. Blood from an artery is bright red in color and comes in spurts; that from a vein is dark red and comes in a steady flow. Aside from the obvious flow of blood from a wound or body orifice, massive hemorrhage can be detected by other signs, such as restlessness, cold and clammy skin, thirst, increased and thready pulse, rapid and shallow respirations, and a drop in blood pressure. If the hemorrhage continues unchecked, the patient may complain of visual disturbances, ringing in the ears, or extreme weakness.

capillary hemorrhage oozing of blood from minute vessels.

cerebral hemorrhage a hemorrhage into the cerebrum; one of the three main causes of cerebral vascular accident (stroke syndrome).

concealed hemorrhage internal hemorrhage.

fibrinolytic hemorrhage that due to abnormalities of fibrinolysis and not hypofibrinogenemia.

internal hemorrhage that in which the extravasated blood remains within the body.

intracranial hemorrhage bleeding within the cranium, which may be extradural, subdural, subarachnoid, or cerebral.

petechial hemorrhage subcutaneous hemorrhage occurring in minute spots.

postpartum hemorrhage that which follows soon after labor.

primary hemorrhage that which soon follows an injury.

secondary hemorrhage that which follows an injury after a considerable lapse of time.

capillary hemorrhage

an oozing of blood from the capillaries.

capillary hemorrhage

Bleeding from minute blood vessels, present in all bleeding. When large vessels are not injured, capillary bleeding may be controlled by simple elevation and pressure with a sterile dry compress.

hemorrhage

the escape of blood from a ruptured vessel. Hemorrhage can be external, internal, or into the skin or other tissues. Blood from an artery is bright red in color and comes in spurts; that from a vein is dark red and comes in a steady flow.

Hemorrhages in particular anatomical sites may be found under their specific anatomical headings.

fibrinolytic hemorrhage

that due to abnormalities in the fibrinolytic system and not dependent on hypofibrinogenemia.

internal hemorrhage

that which occurs into cavities, e.g. hemoperitoneum, or into tissues, e.g. vulvar hematoma in mares. The only evidence of illness may be extreme pallor and weakness. There may be moderate dyspnea and other signs related to the distention of individual organs.

see hemoperitoneum.

intra-articular hemorrhage

intracranial hemorrhage

bleeding within the cranium, which may be extradural, subdural, subarachnoid or cerebral.

intraocular hemorrhage

see hyphema.

mesenteric hemorrhage

uncommon syndrome caused by leakage of blood into the potential space between the two serosal layers of the mesentery. An extensive hemorrhage causes severe abdominal pain, shock, some blood-staining of peritoneal fluid and leakage of blood into the intestinal lumen.

paraneoplastic hemorrhage

a variety of hemostatic disorders develop in association with neoplasia in animals and may result in disseminated intravascular coagulation and hemorrhage. Called also cancer-associated hemorrhage.

peritoneal hemorrhage

see hemoperitoneum.

petechial hemorrhage

subcutaneous hemorrhage occurring in minute spots.

postpartum hemorrhage

that which follows soon after parturition.

primary hemorrhage

that which soon follows an injury.

secondary hemorrhage

that which follows an injury after a considerable lapse of time.

subcutaneous hemorrhage

causes a soft, painless fluctuating swelling capable of being moved easily. Paracentesis reveals the presence of whole blood.
