Overview
Impacted fetal head refers to a complication during cesarean delivery where the fetal head becomes lodged deeply in the maternal pelvis, complicating delivery and posing significant risks to both maternal and neonatal outcomes 1.Diagnosis
Clinical presentation includes prolonged labor, full cervical dilatation, and difficulty in delivering the fetal head 1.
Obstetric maneuvers and imaging (e.g., ultrasound) may be used to assess the degree of impaction 1.
No specific grading system universally accepted; clinical judgment and imaging findings guide assessment 1.Management
Manual disimpaction techniques by skilled obstetricians are first-line interventions 1.
In cases refractory to manual methods, surgical assistance (e.g., obstetric operative vaginal delivery or cesarean section modifications) may be required 1.
Prophylactic use of tocolytic agents (e.g., oxytocin) to manage uterine contractions and facilitate delivery is common 1.
Neonatal monitoring for skull fractures, brain hemorrhage, and hypoxic-ischemic encephalopathy post-delivery is essential 1.Special Populations
Pregnancy: Increased risk in emergency cesarean deliveries, particularly with prolonged labor 1.
Neonatal outcomes: Higher risk of neonatal complications such as skull fractures and brain injuries 1.Key Recommendations
Prompt recognition and intervention by skilled obstetric personnel are crucial to minimize maternal and neonatal risks (Evidence: Strong 1).
Utilize imaging (ultrasound) to assess the degree of impaction and guide management strategies (Evidence: Moderate 1).
Consider prophylactic neonatal monitoring for potential neurological injuries following delivery (Evidence: Expert opinion 1).References
