Hemorrhages are serious medical conditions that can have life-threatening consequences if left untreated. These occur when blood vessels rupture, causing blood to leak into surrounding tissues or organs. Understanding the signs, causes, and treatment options for hemorrhages is crucial for prompt medical intervention and improved outcomes.
This guide delves into the various aspects of hemorrhages, covering their symptoms, underlying causes, and available treatment approaches. It aims to provide readers with essential knowledge to recognize potential hemorrhages and seek timely medical attention. By exploring these key areas, individuals can better understand the importance of early detection and appropriate management of hemorrhages to minimize potential complications and promote recovery.
Understanding Hemorrhages
Hemorrhage refers to the acute loss of blood from a damaged blood vessel, which can be either external or internal. External bleeding occurs from a body orifice or a traumatic wound, while internal bleeding requires a high level of clinical suspicion obtained through a thorough history and physical, laboratory tests, imaging, and close monitoring of vital signs. Hemorrhage has a significant impact on mortality, especially in the acute trauma population.
The pathophysiology of hemorrhage involves damage to one or more blood vessels, leading to blood loss. The severity depends on the location and size of the affected blood vessel(s). In a healthy adult, there is an average of 4.5 to 5.5 liters or 70 to 90 ml/kg of circulating blood. Most adults can tolerate losing up to 14% of their blood volume without physical symptoms or deviations in vital signs. The severity of hemorrhage is divided into a class system organized by the percent of blood volume loss, ranging from Class I (up to 15% blood volume loss) to Class IV (greater than 40% blood volume loss).

Hemorrhages can be classified based on their anatomic location:
- Epidural hemorrhage: Bleeding into the potential space between the dura and the inner table of the skull, commonly caused by skull fractures damaging arterial or venous vessels.
- Subdural hemorrhage: Bleeding into the subdural space, often due to stretching, breaking, or tearing of vessels traversing between the brain and skull.
- Subarachnoid hemorrhage (SAH): Bleeding into the subarachnoid space, which can be traumatic or non-traumatic (e.g., aneurysmal rupture).
- Intraparenchymal hemorrhage: Bleeding involving the cerebral hemispheres, caused by various factors such as hypertension, arteriovenous malformation (AVM), amyloid angiopathy, aneurysm rupture, tumor, coagulopathy, infection, vasculitis, and trauma.
Prompt recognition and appropriate management of hemorrhages are crucial to minimize potential complications and promote recovery.
Recognizing Hemorrhage Symptoms
Recognizing the signs and symptoms of hemorrhage is crucial for prompt medical intervention. Hemorrhage symptoms can vary depending on whether the bleeding is external or internal.
External Bleeding Signs
External bleeding is visible and can be identified by the following signs:
- Blood volume equal to about half a soda can (less in a small child or infant)
- Blood flowing continuously or spurting
- Signs and symptoms of shock
To recognize life-threatening external bleeding, look at the amount of blood (volume) and how the blood moves (flow).
Internal Bleeding Symptoms
Internal bleeding occurs within the body and can be more challenging to identify. Symptoms may include:
- Pain at the injured site
- Swollen, tight abdomen
- Nausea and vomiting
- Pale, clammy, sweaty skin
- Breathlessness
- Extreme thirst
- Unconsciousness
Specific symptoms may vary depending on the location of the internal bleeding:
- Head: weakness, numbness, tingling, severe headache, difficulty swallowing or speaking, altered consciousness
- Chest or abdomen: abdominal pain, shortness of breath, chest pain, dizziness, bruising around the navel or sides of the abdomen
- Muscles or joints: pain, swelling, limited mobility

Hypovolemic Shock
Hemorrhage can lead to hypovolemic shock, a life-threatening condition caused by significant blood loss. Signs and symptoms of hypovolemic shock include:
- Rapid, weak heartbeat
- Rapid breathing
- Pale, gray, or cool moist skin
- Altered level of responsiveness
- Excessive thirst
Recognizing these symptoms and seeking immediate medical attention is essential for the proper management of hemorrhage and the prevention of complications.
Common Causes of Hemorrhages
Hemorrhages can have various causes, ranging from traumatic injuries to underlying medical conditions and medication side effects. Understanding these causes is crucial for prompt recognition and appropriate management.
Trauma and injuries are among the leading causes of hemorrhage. Blunt or penetrating trauma to the head, neck, chest, abdomen, or pelvis can result in significant bleeding. Damage to blood vessels outside the bone but coursing with it anatomically can also lead to hemorrhage if injured. Hemorrhage secondary to traumatic injury is a major cause of death in Americans up to age 46.
Medical disorders can also contribute to hemorrhages. Coagulation disorders, platelet disorders, liver disease, and vitamin deficiencies can impair the body’s ability to form clots and stop bleeding. Malignancies and gastrointestinal conditions such as varices, ulcers, esophagitis, gastritis, and duodenitis can cause bleeding in the digestive tract. Aortic dissection, gastrointestinal neoplasms, angiodysplasias, diverticula, and hemorrhoids are other potential causes of hemorrhage.
Medication side effects can increase the risk of bleeding. Anticoagulant medications like warfarin (Coumadin®) and antiplatelet drugs such as aspirin, clopidogrel (Plavix®), and apixaban (Eliquis®) can potentiate bleeding. These medications interfere with the body’s clotting mechanisms and may cause excessive bleeding in case of injury or underlying medical conditions.
Recognizing the common causes of hemorrhage is essential for effective prevention, early detection, and timely intervention. Healthcare providers should assess patients for risk factors such as trauma history, medical conditions, and medication use to identify those at higher risk of bleeding complications.
Treatment Approaches
The management of hemorrhage depends on its anatomic location, severity, patient presentation, and available resources. Resuscitation with IV fluids is necessary if the patient shows signs of hypovolemia. Basic fluid resuscitation involves placing two large bore IVs, infusing normal saline or lactated ringer, and beginning a transfusion protocol. Blood products should be administered in equivalent amounts (1:1:1 PRBCs, FFP, platelets) and transfused as needed. The goals of treatment are to restore intravascular volume and maintain oxygen delivery until the source of bleeding can be resolved.
Emergency First Aid
For traumatic external wounds, direct pressure and placement of tourniquets proximal to the source of the hemorrhage can be life-saving interventions. If you can’t stop external bleeding or suspect internal bleeding, get immediate medical help.
Medical Interventions
Treatment for a hemorrhage depends on its location, severity, underlying cause, and presence of other conditions or injuries. If the cause is unknown and/or the bleeding is severe, hospital treatment is necessary. The healthcare team will find the cause and treat it appropriately. Treatment may include:
- IV fluids
- Blood transfusions
- Vitamin K injections (to help stop bleeding if it’s caused by medication like warfarin)

Surgical Procedures
Surgery may be required to control the bleeding and reduce pressure in the brain caused by excess fluid. After a hemorrhagic stroke, craniotomy might be necessary to remove the blood and relieve pressure on the brain if the area of bleeding is large enough. Surgery may also be used to repair blood vessel problems associated with hemorrhagic strokes, such as:
- Surgical clipping for aneurysms
- Surgical AVM removal
- Angioplasty and stents
Recovery and Aftercare
Following a hemorrhage, patients need education on what to expect during recovery and how to avoid future recurrence. Taking the time needed to rest is important. Don’t be afraid to ask for help from friends and family. Arrange for assistance with housework, cooking, and childcare. Have reasonable expectations, as recovery from a hemorrhage takes longer than recovery from a birth with normal blood loss.
Conclusion
Hemorrhages are serious medical conditions that demand swift action and proper care. This guide has shed light on the various types of hemorrhages, their symptoms, underlying causes, and available treatment options. Understanding these aspects is crucial to recognize potential bleeding problems and seek timely medical help, which can make a big difference in the outcome.
Proper management of hemorrhages involves a mix of emergency first aid, medical interventions, and sometimes surgical procedures. The road to recovery after a hemorrhage can be challenging, but with the right care and support, patients can bounce back. By staying informed about the risks and knowing what to look out for, we can better protect ourselves and our loved ones from the potentially life-threatening consequences of hemorrhages.
