Understanding Subgaleal Haemorrhage: Causes, Symptoms, And Treatment

Subgaleal haemorrhage is a rare but potentially life-threatening condition that involves bleeding between the scalp and the skull. This medical emergency often occurs in newborns but can also affect adults due to trauma or other underlying conditions. Recognizing the signs and symptoms early can make a significant difference in the outcome. Subgaleal haemorrhage requires prompt medical attention to prevent complications such as severe blood loss, shock, or even death. Understanding its causes, risk factors, and treatment options is crucial for both healthcare professionals and the general public.

Although subgaleal haemorrhage is uncommon, it is essential to be aware of its potential causes, which include traumatic injuries, complications during childbirth, or the use of medical instruments like forceps or vacuum extractors. In newborns, this condition can develop quickly and may present as swelling or a "boggy" feeling on the scalp. For adults, trauma to the head, such as from a fall or car accident, can lead to this condition. Early diagnosis and intervention are critical to ensure the best possible recovery.

Subgaleal haemorrhage is not widely discussed in mainstream health conversations, but its severity demands attention. Whether you're a parent, caregiver, or healthcare provider, knowing how to identify and respond to this condition can save lives. In this article, we will explore the causes, symptoms, and treatment options for subgaleal haemorrhage, as well as answer frequently asked questions about this condition. By the end of this guide, you'll have a comprehensive understanding of subgaleal haemorrhage and its implications.

What is Subgaleal Haemorrhage?

Subgaleal haemorrhage refers to bleeding that occurs in the potential space between the scalp's galea aponeurotica and the periosteum of the skull. This area, known as the subgaleal space, can accumulate a significant amount of blood due to its loose connective tissue. In severe cases, the blood loss can lead to hypovolemic shock, a condition where the body loses too much blood to maintain normal circulation.

While subgaleal haemorrhage is most commonly associated with newborns, it can also occur in adults who experience blunt force trauma to the head. The condition is often underdiagnosed because its symptoms can mimic other less severe conditions. Understanding what subgaleal haemorrhage is and how it develops is the first step in ensuring timely intervention and treatment.

What Causes Subgaleal Haemorrhage?

The causes of subgaleal haemorrhage vary depending on the age group affected. In newborns, the condition is often linked to complications during delivery, particularly when medical instruments such as forceps or vacuum extractors are used. These tools can inadvertently cause trauma to the scalp, leading to bleeding in the subgaleal space.

In adults, subgaleal haemorrhage is typically the result of blunt force trauma to the head, such as from a fall, car accident, or assault. Other contributing factors may include blood clotting disorders or the use of blood-thinning medications. Understanding the causes of subgaleal haemorrhage can help healthcare providers take preventive measures and reduce the risk of complications.

How is Subgaleal Haemorrhage Diagnosed?

Diagnosing subgaleal haemorrhage requires a combination of clinical evaluation and imaging tests. In newborns, doctors may notice swelling or a "boggy" feeling on the scalp during a physical examination. For adults, symptoms such as severe headache, dizziness, or loss of consciousness may prompt further investigation.

Imaging tests such as CT scans or MRIs are often used to confirm the diagnosis. These tests can help identify the extent of the bleeding and determine whether surgical intervention is necessary. Early and accurate diagnosis is critical to preventing complications and ensuring a positive outcome.

What Are the Symptoms of Subgaleal Haemorrhage?

The symptoms of subgaleal haemorrhage can vary depending on the severity of the condition and the age of the patient. In newborns, common symptoms include:

• Swelling or a "boggy" feeling on the scalp
• Pallor or paleness of the skin
• Rapid heart rate
• Low blood pressure

In adults, symptoms may include severe headache, nausea, vomiting, dizziness, or loss of consciousness. Recognizing these symptoms early can help ensure prompt medical attention and treatment.

Is Subgaleal Haemorrhage Treatable?

Yes, subgaleal haemorrhage is treatable, but the approach depends on the severity of the condition. In mild cases, conservative treatment such as close monitoring and supportive care may be sufficient. However, in severe cases, surgical intervention may be necessary to stop the bleeding and prevent further complications.

Treatment options may include blood transfusions to replace lost blood, medications to stabilize blood pressure, or surgical procedures to evacuate the hematoma. The key to successful treatment is early diagnosis and intervention. With proper care, most patients can recover fully from subgaleal haemorrhage.

Subgaleal Haemorrhage in Newborns

Subgaleal haemorrhage is most commonly observed in newborns, particularly those who experience complications during delivery. The use of medical instruments such as forceps or vacuum extractors increases the risk of this condition. In some cases, the bleeding may not become apparent until several hours after birth.

Parents and caregivers should be vigilant for signs of subgaleal haemorrhage, such as swelling on the scalp, pallor, or rapid heart rate. Early medical intervention can prevent complications and ensure the best possible outcome for the newborn.

Risk Factors for Subgaleal Haemorrhage

Several factors can increase the risk of subgaleal haemorrhage, including:

• Use of forceps or vacuum extractors during delivery
• Difficult or prolonged labor
• Blood clotting disorders
• Blunt force trauma to the head

Understanding these risk factors can help healthcare providers take preventive measures and reduce the likelihood of subgaleal haemorrhage.

How Can Subgaleal Haemorrhage Be Prevented?

Preventing subgaleal haemorrhage involves minimizing risk factors and ensuring proper care during delivery. Healthcare providers should use medical instruments such as forceps or vacuum extractors with caution and only when necessary. Additionally, educating parents and caregivers about the signs and symptoms of subgaleal haemorrhage can help ensure early detection and treatment.

For adults, wearing protective headgear during activities that pose a risk of head injury can help prevent subgaleal haemorrhage. Regular medical check-ups and managing underlying conditions such as blood clotting disorders can also reduce the risk.
