Subgaleal Hemorrhage in Newborns

Subgaleal hemorrhage is a rare but serious condition in newborns. It involves bleeding under the scalp, causing swelling and other symptoms. This usually happens during birth, often due to the use of forceps or vacuum extraction.

It’s important to quickly diagnose and treat subgaleal hemorrhage to avoid serious problems. Doctors need to watch for signs of bleeding and swelling in newborns, mainly those who had a tough delivery. Treatment may include supportive care, monitoring, and sometimes blood transfusions or surgery.

This article covers subgaleal hemorrhage in newborns. We’ll look at its causes, symptoms, how it’s diagnosed, and treatment options. Understanding this condition helps healthcare providers and parents work together for the best care of affected babies.

What is Subgaleal Hemorrhage?

Subgaleal hemorrhage is a bleeding disorder found in newborns. It happens due to birth trauma or delivery issues. This condition causes bleeding in a space between the skull and scalp.

It’s different from other bleeding issues like subdural or epidural hematomas. Subgaleal hemorrhage happens outside the skull but under the scalp. The space can hold a lot of blood, causing big problems for newborns.

Anatomy of the Scalp and Skull

To understand subgaleal hemorrhage, knowing the scalp and skull anatomy is key. The scalp has several layers:

• Skin
• Connective tissue
• Aponeurosis (epicranial aponeurosis)
• Loose areolar tissue (subgaleal space)
• Periosteum
• Skull bones

The subgaleal space is between the skull periosteum and the scalp aponeurosis. It has veins that connect the brain’s veins to the scalp’s veins. Damage during birth can cause blood to build up, leading to subgaleal hemorrhage.

Causes of Subgaleal Hemorrhage in Newborns

Subgaleal hemorrhage in newborns can happen for many reasons. Birth trauma and delivery issues are the top causes. Knowing these risks helps prevent and treat this serious condition.

Birth Trauma and Delivery Complications

Hard or long labors, and tools used in delivery, raise the risk of subgaleal hemorrhage. Forceps delivery and vacuum extraction are two big issues.

Forceps help guide the baby’s head during birth. But, misuse can hurt the scalp and skull, causing bleeding. Vacuum extraction, which uses suction, can also lead to scalp injuries and bleeding.

Risk Factors for Developing Subgaleal Hemorrhage

Other factors can also raise a newborn’s risk of subgaleal hemorrhage:

• Macrosomia (high birth weight)
• Prolonged second stage of labor
• Cephalopelvic disproportion (baby’s head is too large to pass through the mother’s pelvis)
• Abnormal fetal presentation (breech or face presentation)
• Prematurity
• Coagulation disorders in the newborn

Head trauma during birth, like skull fractures, can also cause subgaleal hemorrhage. Healthcare providers must watch for these risks to prevent this severe condition.

Signs and Symptoms of Subgaleal Hemorrhage

Subgaleal hemorrhage in newborns shows different signs and symptoms that need quick action. A key sign is scalp swelling, which can spread and feel soft. This swelling can grow fast, sometimes reaching the neck and feeling like it’s floating when touched.

Newborns with subgaleal hemorrhage may also show signs of shock from losing a lot of blood. These signs include pale skin, feeling tired, fast heart rate, and weak blood flow. They might also have trouble breathing, be irritable, and have trouble eating.

The bleeding in the skull can also cause a drop in blood counts and an increase in bilirubin. Here’s a table showing common lab findings in newborns with subgaleal hemorrhage:

Healthcare providers must watch newborns closely, even more so if they’re at risk for subgaleal hemorrhage. Catching it early and treating it can stop serious problems from happening.

Diagnostic Tests for Subgaleal Hemorrhage

Quickly finding out if a newborn has a subgaleal hemorrhage is very important. Doctors use a few key methods to spot this serious issue. These include checking the baby physically, using imaging studies, and doing lab tests.

Physical Examination

The first step is a detailed physical check. Doctors look for signs like swelling on the skull, pale skin, and shock. They might find:

Imaging Studies

Imaging is key in diagnosing subgaleal hemorrhage. It helps rule out other serious brain bleeds. The main imaging tools are:

• Cranial ultrasound: A bedside test that can detect fluid collections in the subgaleal space
• Computed tomography (CT) scan: Provides detailed images of the brain and skull, helping to differentiate subgaleal hemorrhage from other intracranial bleeds
• Magnetic resonance imaging (MRI): Reserved for complex cases or to assess long-term effects on brain development

Laboratory Tests

Blood tests are vital for checking how bad the hemorrhage is. They help doctors decide the best treatment. Important tests include:

• Complete blood count (CBC): Assesses the degree of anemia and thrombocytopenia resulting from blood loss
• Coagulation studies: Evaluate the newborn’s clotting function to rule out underlying coagulopathy that may exacerbate bleeding
• Metabolic panel: Monitors electrolyte imbalances and organ function, which can be impacted by severe hemorrhage

By using physical checks, imaging, and lab tests together, doctors can spot subgaleal hemorrhage right away. This helps start the right treatment quickly. It’s all about making sure the baby gets the best care possible.

Treatment Options for Subgaleal Hemorrhage in Newborns

Quick action is key for newborns with subgaleal hemorrhage, a serious bleeding issue. The main goal is to keep the baby stable, stop more bleeding, and handle any problems that come up. Treatment usually includes supportive care, watching the baby closely, and medical steps based on how bad the bleeding is.

Supportive Care and Monitoring

First, treatment focuses on keeping the newborn’s basic functions going. This includes:

It’s also important to watch the baby’s brain function, head size, and how the swelling is doing. This helps track how the bleeding and swelling are changing.

Blood Transfusions

Many newborns with subgaleal hemorrhage need blood transfusions. This is to replace lost blood and keep blood flowing well. They usually get packed red blood cells to carry more oxygen. Fresh frozen plasma and platelets might also be given to fix any bleeding problems.

Surgical Intervention

In very bad cases, surgery might be needed to stop the bleeding or ease brain pressure. Procedures could include:

• Drainage of the subgaleal space: Taking out the blood to lower pressure and stop more bleeding
• Ligation of bleeding vessels: Finding and tying off the blood vessels to stop the bleeding
• Decompressive craniectomy: Taking part of the skull off to reduce brain pressure in very bad cases

Whether or not to have surgery depends on how sick the baby is, how bad the bleeding is, and if there are serious complications. It’s important for doctors, including neonatologists and neurosurgeons, to work together to help the baby.

Complications of Subgaleal Hemorrhage

Subgaleal hemorrhage in newborns can often be managed well with quick diagnosis and treatment. But, there are serious complications that can happen. One major issue is hypovolemic shock, caused by too much blood loss. This can harm organs and is very dangerous if not treated fast.

Another problem is anemia, caused by blood loss. This can make the skin look pale, make the baby tired, and cause a fast heartbeat. Jaundice, or yellow skin and eyes, might also happen because of broken-down red blood cells.

In some cases, subgaleal hemorrhage can lead to intracranial hemorrhage, or bleeding in the brain. This can happen if the bleeding spreads and presses on the brain. Symptoms include seizures, being very sleepy, and odd neurological signs. Quick imaging with CT or MRI can spot this problem.

Also, newborns with severe subgaleal hemorrhage might face skull fractures if there was a lot of trauma during birth. Skull fractures can make things worse and might need surgery or more treatment.

To avoid these complications, it’s key to spot and treat subgaleal hemorrhage right away. Keeping a close eye on the baby’s vital signs, brain function, and lab results can catch any problems early. With the right care, many babies with subgaleal hemorrhage can get better without lasting harm.

Prognosis and Long-term Outlook for Newborns with Subgaleal Hemorrhage

The future for newborns with subgaleal hemorrhage can vary. Most infants get better with quick treatment. But, some may face lasting effects from this birth injury. It’s important for families and doctors to understand this.

Factors Influencing Prognosis

Several factors affect a newborn’s future with subgaleal hemorrhage. The size of the hemorrhage is a big factor. Babies with bigger hemorrhages might have a harder time recovering. Also, how fast they get treated matters a lot.

Early treatment helps reduce neonatal head trauma and aids in recovery.

Potential Long-term Effects

Some newborns with subgaleal hemorrhage may face long-term challenges. These can include:

• Developmental delays in motor skills, language, or cognitive abilities
• Learning difficulties or intellectual disabilities
• Seizures or epilepsy
• Cerebral palsy or other neurological disorders

It’s key to keep up with regular check-ups. This helps spot any long-term issues early. With the right support, families can help their children overcome these challenges.

Prevention of Subgaleal Hemorrhage in Newborns

It’s very important to prevent subgaleal hemorrhage in newborns. Healthcare providers must identify high-risk pregnancies and use safe delivery methods. This can greatly lower the risk of this serious condition.

Identifying High-risk Pregnancies

Knowing early if a pregnancy is at higher risk helps a lot. This allows for better planning and care during delivery. Some things that might raise the risk include:

Safe Delivery Practices

Safe delivery practices are key to avoiding birth trauma and subgaleal hemorrhage. Important steps include:

• Using forceps delivery and vacuum extraction wisely, only when really needed
• Using the right technique and position during instrumental deliveries to avoid harm
• Keeping a close eye on the baby’s health during delivery to catch any problems early
• Having skilled doctors and teams ready to help if needed

By focusing on prevention and safe delivery, we can lower the risk of subgaleal hemorrhage. This helps keep newborns safe and healthy.

Coping and Support for Families Affected by Subgaleal Hemorrhage

When a newborn is diagnosed with subgaleal hemorrhage, it’s a tough time for the whole family. This neonatal head trauma can be overwhelming. Families need a strong support system and access to helpful resources.

Parents and caregivers might feel scared, guilty, or anxious. It’s important to know that subgaleal hemorrhage isn’t anyone’s fault. Seeking support shows strength. Talking to loved ones, friends, or a mental health professional can help.

Meeting other families who’ve faced similar challenges can offer comfort and insights. Support groups, both in-person and online, are great for sharing stories and finding understanding. Organizations like:

• The Brain Injury Association of America
• The March of Dimes
• The Neonatal Brain Injury Foundation

Families may also need help with practical things like insurance and medical appointments. Social workers and case managers can guide them. They help find the resources needed.

As the newborn recovers, ongoing support and monitoring are key. Early intervention services like physical and occupational therapy can help. Regular check-ups with specialists ensure the child gets the best care.

No family has to face subgaleal hemorrhage alone. With the right support, families can manage its impact. They can focus on their child’s health and well-being.
