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.

hem′or·rhag′ic (hĕm′ə-răj′ĭk) adj.

hemorrhage

[hem′ərij]
Etymology: Gk, haima + rhegnynei, to gush
a loss of a large amount of blood in a short period, either externally or internally. Hemorrhage may be arterial, venous, or capillary.
observations Symptoms of massive hemorrhage are related to hypovolemic shock: rapid, thready pulse; thirst; cold, clammy skin; sighing respirations; dizziness; syncope; pallor; apprehension; restlessness; and hypotension. If bleeding is contained within a cavity or joint, pain will develop as the capsule or cavity is stretched by the rapidly expanding volume of blood.
interventions Effort is directed to stopping the hemorrhage. If hemorrhage is external, pressure is applied directly to the wound or to the appropriate pressure points. The part of the body that is wounded may be elevated. Ice, applied directly to the wound, may slow bleeding by causing vasoconstriction. Body temperature may be maintained by keeping the person covered and flat. If an extremity is wounded, and if the bleeding is severe, a tourniquet may be applied proximal to the wound. Also spelled haemorrhage. -hemorrhagic, adj.

hemorrhage

(hem'(o-)raj) [ hem- + -rrhage]
Blood loss. The term is usually used for episodes of bleeding that last more than a few minutes, compromise organ or tissue perfusion, or threaten life. The most hazardous forms of blood loss result from arterial bleeding, internal bleeding, or bleeding into the cranium. The risk of uncontrolled bleeding is greatest in patients who have coagulation disorders or take anticoagulant drugs.hemorrhagic (hem-o-raj'ik), adjective See: table

Symptoms

Orthostatic dizziness, weakness, fatigue, shortness of breath, and palpitations are common symptoms of hemorrhage. Signs of hemorrhage include tachycardia, hypotension, pallor, and cold moist skin.

Treatment

Pressure should be applied directly to any obviously bleeding body part, and the part should be elevated. Cautery may be used to stop bleeding from visible vessels. Ligation of blood vessels, surgical removal of hemorrhaging organs, or the instillation of sclerosants is often effective in managing internal hemorrhage. Procoagulants (such as vitamin K, fresh frozen plasma, cryoprecipitate, desmopressin) may be administered to patients with primary or drug-induced bleeding disorders. Transfusions of red blood cells may be given if bleeding compromises heart or lung function or threatens to do so because of its pace or volume.

For trauma patients with massive bleeding, the experienced nurse or emergency care provider may apply pneumatic splints or antishock garments during patient transportation to the hospital. These devices may prevent hemorrhagic shock.

CAUTION!

Standard precautions should be used for all procedures involving contact with blood or wounds.

antepartum hemorrhage

Excessive blood loss during the prenatal period, most commonly associated with spontaneous or induced abortion, ruptured ectopic pregnancy, placenta previa, or abruptio placentae.

arterial hemorrhage

A hemorrhage from an artery. In arterial bleeding, which is bright red, the blood ordinarily flows in waves or spurts; however, the flow may be steady if the torn artery is deep or buried.

First Aid

Almost all arterial bleeding can be controlled with direct pressure to the wound. If it cannot be controlled with applied pressure, the responsible artery may need to be surgically ligated. See: arterial bleeding for table; pressure point

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.

carotid artery hemorrhage

Bleeding from the carotid artery. This type of hemorrhage can be rapidly fatal because it may be profuse and may deprive the brain of oxygen.

First Aid

The wound should be compressed with the thumbs placed transversely across the neck, both above and below the wound, and the fingers directed around the back of the neck to aid in compression. Urgent surgical consultation is required.

cerebral hemorrhage

Bleeding into the brain, a common cause of stroke. See: stroke

Etiology

It usually results from rupture of aneurysm, extremely high blood pressure, brain trauma, or brain tumors.

Symptoms

Most people with intracerebral bleeding experience headache. This type of hemorrhage may cause symptoms of stroke (such as unconsciousness, apnea, vomiting, hemiplegia) and death. There may be speech disturbance, incontinence of the bladder and rectum, or other findings, depending on the area of brain damage.

Treatment

Supportive therapy is needed to maintain airway and oxygenation. Neurosurgical consultation should be promptly obtained. Hydration and fluid and electrolyte balance should be maintained. Rehabilitation may include physical therapy, speech therapy, and counseling.

choroidal hemorrhage

Bleeding into the choroid of the eye, a complication of systemic anticoagulation, hypertension, macular degeneration, some ocular surgeries, and ocular metastases of malignant tumors. Visual impairment resulting from the bleeding is usually significant.

eight-ball hemorrhage

A hyphema in which the anterior chamber of the eye fills completely with blood.

fetomaternal hemorrhage

Abbreviation: FMH
The transfer of fetal blood cells through the placenta into the maternal circulation, usually at the time of delivery. Less than 1 ml is considered normal, but greater than 30 ml, as in trauma or placental abruption, is a major cause of fetal morbidity and death. The condition often occurs during pregnancy and may result in the immunization of the mother against Rh antigens in the fetus, esp. when the mother is Rh-negative and the child is Rh-positive. See: Kleihauer-Betke test

fibrinolytic hemorrhage

A hemorrhage due to a defect in the fibrin component in blood coagulation.

gastrointestinal hemorrhage

Gastrointestinal bleeding.

internal hemorrhage

Occult bleeding.

intracranial hemorrhage

Abbreviation: ICH
Bleeding into the cranium. It is a devastating form of stroke with a high rate of mortality.

Patient care

Patients with ICH should be treated emergently with infusions of recombinant factor VIIa in an intensive care unit, where minute-to-minute monitoring of intracranial pressures, blood glucose levels, neurological status, and hemodynamics can be carried out. Patients should initially be kept at bedrest with the head of the bed elevated. Fever should be suppressed and seizures prevented with the administration of anticonvulsant drugs. As the patient stabilizes, rehabilitation supervised by occupational therapists, physical therapists, and speech therapists should be initiated.

hemorrhage of the knee

Bleeding from the knee.

Treatment

If the bleeding is at the knee or below, a pad should be applied with pressure. If the bleeding is behind the knee, a pad should be applied at the site and the leg bandaged firmly. The bandage should be loosened at 12-min to 15-min intervals to prevent arterial obstruction.

lung hemorrhage

Hemorrhage from the lung, with bright red and frothy blood, frequently coughed up.

nasal hemorrhage

Epistaxis.

petechial hemorrhage

Hemorrhage in the form of small rounded spots or petechiae occurring in the skin or mucous membranes.

postmenopausal hemorrhage

Bleeding from the uterus after menopause.

postpartum hemorrhage

Abbreviation: PPH
Hemorrhage that occurs after childbirth. It is a major cause of maternal morbidity and mortality in childbirth. Early postpartum hemorrhage is defined as a blood loss of more than 500 ml of blood during the first 24 hr after delivery. The most common cause is loss of uterine tone caused by overdistention. Other causes include prolonged or precipitate labor; uterine overstimulation; trauma, rupture, or inversion; lacerations of the lower genital tract; or blood coagulation disorders. Late postpartum hemorrhage occurs after the first 24 hr have passed. It usually is caused by retained placental fragments.

Patient care

Many instances of PPH can be prevented with the administration of oxytocin, misoprostol, or other uterotonic medications. The woman's prenatal, labor, and delivery records are reviewed. The presence of risk factors is noted, and the woman's pulse, blood pressure, fundal and bladder status, and vaginal discharge are assessed every 15 min. If the fundus is boggy, it is massaged to stimulate uterine contractions, and then the status of the woman's bladder is assessed. If the bladder is distended, the patient is encouraged to void and then postvoiding fundal status is assessed; if the fundus remains firm after massage, the fundus and vaginal flow are reassessed in 5 min. See: fundal massage

If bleeding does not respond to the above measures or if the fundus remains firm and the patient exhibits bright red vaginal discharge, retained placental fragments or cervical or vaginal laceration should be suspected; the practitioner who delivered the baby should be notified. Continued massage at this point is contraindicated; the physician or nurse midwife may order uterotonic agents to stimulate uterine contractions. Vital signs should be closely monitored. Common findings in hemorrhage include an increase in pulse rate, often associated with a drop in blood pressure. Pharmacological agents such as methylergonovine or prostaglandin F2 analogs may be administered intramuscularly or intravenously. If blood loss has been extensive, intravenous infusions or blood transfusion may be needed to combat hypovolemic shock. If the patient exhibits signs of a clotting defect, prompt life-saving treatment is imperative. See: disseminated intravascular coagulation

The patient is prepared for and the primary caregiver is assisted with examination of the uterine cavity, removal of any placental fragments, or repair of any lacerations. To reduce the patient's anxiety, all procedures are explained, support and comfort are provided, and the mother is assured that her newborn is receiving good care.

primary hemorrhage

A hemorrhage immediately following any trauma.

retroperitoneal hemorrhage

Bleeding into the retroperitoneal space.

secondary hemorrhage

1. A hemorrhage occurring some time after primary hemorrhage, usually caused by sepsis and septic ulceration into a blood vessel. It may occur after 24 hr or when a ligature separates, usually between the 7th and 10th days.
2. Bleeding from the mother's uterus or the infant's umbilicus, resulting from a septic infection.

splinter hemorrhage

A small linear hemorrhage under the fingernails or toenails. It may be due to subacute bacterial endocarditis.

subarachnoid hemorrhage

Abbreviation: SAH
Bleeding into the subarachnoid space of the brain, usually because of the rupture of an intracranial aneurysm or arteriovenous malformation, and occasionally because of hypertensive vascular disease. The bleeding causes intense headache pain, often with nausea and vomiting, loss of consciousness, paralysis, and, in some cases, coma, decerebrate posturing, and brain death. About 30,000 Americans are affected annually. Prompt diagnosis is facilitated by neuroimaging or lumbar puncture. A neurosurgical consultation should be obtained.

SUBCONJUNCTIVAL HEMORRHAGE

subconjunctival hemorrhage

Rupture of the superficial capillaries with associated hemorrhage into the subconjunctival space.

Etiology

Subconjunctival hemorrhage can result from blunt trauma to the eye or from increased intracranial or intraocular pressure.

Symptoms

Patients have visible bleeding between the sclera and the conjunctiva.

Treatment

A subconjunctival hemorrhage normally resolves within 1 to 7 days.

illustration

thigh hemorrhage

Bleeding at the upper part of the thigh, near the groin.

Treatment

A pad or gauze should be inserted into the wound and pressure applied. Failure of the bleeding to stop requires surgical consultation.

typhoid hemorrhage

Gastrointestinal (GI) bleeding due to ulceration of the upper GI tract, typically during the second or third week of untreated typhoid.

uterine hemorrhage

Hemorrhage into the cavity of the uterus. The three types of pathologic uterine hemorrhage are essential uterine hemorrhage (metropathia haemorrhagica), which occurs with pelvic, uterine, or cervical diseases; intrapartum hemorrhage, which occurs during labor; and postpartum hemorrhage, which occurs after the third stage of labor. The last may be caused by rupture, lacerations, relaxation of the uterus, hematoma, or retained products of conception, including the placenta or membrane fragments.

Etiology

Common causes are trauma; congenital abnormalities; pathologic processes (such as tumors; infections, esp. of the alimentary, respiratory, and genitourinary tracts); and generalized vascular disorders such as purpuras and coagulation defects. Hemorrhage may also result from premature separation of the placenta, particularly with extravasation into the uterine musculature, and from retained products of conception after abortion or delivery. See: abruptio placentae; Couvelaire uterus

Treatment

An umbrella pack will apply pressure to the uterine arterial supply. When ultrasonography reveals that retained placental fragments are the source of hemorrhage, they are usually removed by suction or surgical curettage. If the uterus is flaccid, it can usually be stimulated to contract by administering intravenous oxytocin. The patient may need transfusion and, in some cases, surgery to prevent fatal hemorrhage.

variceal hemorrhage

See: esophageal varix

venous hemorrhage

Hemorrhage from a vein, characterized by steady, profuse bleeding of rather dark blood.

Patient care

The patient should be reassured while direct pressure to the wound is applied and the affected body part is elevated. If bleeding does not stop after 15 min of direct pressure, evaluation by a health care provider is advisable. Vital signs should be monitored whenever bleeding does not stop with direct pressure, and IV fluids should be initiated as necessary to prevent hypovolemic shock.

vicarious hemorrhage

Hemorrhage from one part as a result of suppression of bleeding in another part.
See: vicarious menstruation.

haemorrhage

The escape of blood from any part of the vascular system. Note: also spelt hemorrhage.
blot haemorrhage A form of intraretinal haemorrhage often noted in background (nonproliferative) diabetic retinopathy, branch retinal vein occlusion, carotid occlusive disease and child abuse. The haemorrhage is located within the inner retina and is limited by the orientation of the inner nuclear and plexiform layers. A small blot haemorrhage is often referred to as a 'dot' haemorrhage.
flame haemorrhage  See preretinal haemorrhage.
preretinal haemorrhage Haemorrhage occurring between the retina and the vitreous body. It is usually large and often shaped like a D with the straight edge at the top. Syn. subhyaloid haemorrhage. Others are flame shaped and occur at the level of the nerve fibre layer and tend to parallel the course of the nerve fibres (flame haemorrhage). Retinal haemorrhages are usually round and originate in the deep capillaries of the retina. Retinal and preretinal haemorrhages usually absorb after a period of time (except those that break into the vitreous), but subarachnoid haemorrhage (which is usually due to a rupture of an aneurysm in an artery of the circle of Willis) must be suspected as they often accompany it. See proliferative retinopathy.
subconjunctival haemorrhage A red patch of blood on the conjunctiva of the eye, due to the rupture of a small blood vessel beneath. The condition is nearly always unilateral and the haemorrhage absorbs spontaneously although it frequently alarms the subject. It may be associated with hypertension, especially in people over 50 years of age. See sickle-cell disease.
subarachnoid haemorrhage; subhyaloid haemorrhage See preretinal haemorrhage.

Patient discussion about hemorrhage

Q. Hi, I´m bleeding when I pee,suggestions? I´m 42 years old,and I had a lot of pain days ago just like before when I had a kidney stone and now I´m bleeding when I pee but I don´t know if could be a different problem

A. Thanks everybody, I´m taking care of the problem, all of you are very nice, God bless you.

Q. Can acupuncture cause bleeding? I’m thinking to try acupuncture for back pain I have for many months (long story, so far nothing helped), but I’m afraid it’ll cause bruises and bleeding – last week when the nurse draw blood from my arm she left a green sign that lasted almost a week. Is it dangerous? Can it cause infection?

A. Has blood drawing ever caused an infection? The same way, if the new and sterile needles are used, the risk is very low.

Take care

Q. My husband has a very small mole that was cut.We can not seem to get it to stop bleeding. Any suggestions? tried a shaving pencil, and band-aids of every size. Just will not stop bleeding.

A. In this case, you should go see the doctor who took the mole out, or any dermatologist actually, that can burn the spot a little bit to help it stop bleeding.
