Birth Trauma Flashcards
What is subgaleal hemorrhage?
Bleeding into the potential space of the gala aponeurotica or subaponeurotic area
Associated with vacuum-assisted delivery and can lead to severe hypovolemia and DIC risk.
What are the types of skull fractures?
Linear and depressed
Linear fractures are often asymptomatic and heal spontaneously, while depressed fractures may require surgical intervention.
What is the prognosis for a depressed skull fracture?
Excellent prognosis
Surgical elevation of skull is performed to prevent brain compression.
What causes subarachnoid hemorrhage?
Rupture of bridging veins leading to bleeding into the subarachnoid space
Rare complications include seizures and massive hemorrhage requiring craniotomy.
What is the common cause of facial nerve injury during birth?
Compression of the facial nerve against maternal sacral promontory
Can occur due to incorrect forceps applications or in utero compression.
What are the symptoms of facial nerve injury?
Facial asymmetry
Mild cases resolve in a few days, while full recovery may take weeks to months.
What is caput succedaneum?
Accumulation of serum above the periosteum
Commonly occurs during delivery.
What is cephalohematoma?
Ruptured blood vessels between the periosteum and skull
Accumulates beneath the periosteum.
What constitutes a sentinel event according to JCH?
Any perinatal death or major permanent loss of function unrelated to a congenital condition in an infant >2500g
Highlights the severity of birth trauma.
What are maternal risk factors for birth trauma?
- Diabetes
- Obesity
- Prolongation of pregnancy > 298 days
- Short maternal stature
- Instrumented delivery
These factors increase the risk of birth-related injuries.
What are infant risk factors for birth trauma?
- Macrosomia
- Abnormal presentation
- Large weight gain
- Shoulder dystocia
- History of macrosomic infant
These factors contribute to the likelihood of injury during delivery.
What are the characteristics of superficial lesions in birth trauma?
Bruising and abrasions that are usually benign
Can include lacerations to the scalp, face, cheek, or ear.
What is the significance of subdural hemorrhage?
Bleeding between the dura and arachnoid
Can present asymptomatically or with severe symptoms like seizures and brain stem compression.
What is a common eye injury related to forceps delivery?
Corneal damage
Can lead to permanent vision impairment.
What is a common form of peripheral nerve injury during birth?
Brachial plexus injury
Occurs from lateral traction applied to the infant’s neck.
What are the symptoms of phrenic nerve injury?
- Cyanosis
- Respiratory distress
- Asymmetric chest movement
Indicates potential diaphragm paralysis.
What is a common sign of vocal cord paralysis?
Unilateral paralysis leading to a hoarse or breathy cry
Can present with aspiration risk and GERD.
What is a common complication of intraabdominal organ injuries during birth?
Hematoma formation and risk of rupture
Typically involves the spleen, adrenal glands, and liver.
What is a potential sign of adrenal hemorrhage in infants?
Discoloration of the scrotum
Can be mistakenly evaluated as testicular torsion.
What is the treatment for hematoma in the liver due to birth trauma?
Avoid surgery if possible and manage coagulopathies
Liver injuries can be life-threatening due to vascularity.
