Nerve injuries due to obstetric trauma

Area of Science:

• Obstetrics
• Neonatal Neurology
• Pediatric Surgery

Background:

• Nerve injuries during childbirth are a significant concern, impacting neonatal health.
• Brachial plexus and facial nerve injuries are the most common types, with varying incidence rates.
• Understanding risk factors is crucial for prevention and management strategies.

Purpose of the Study:

• To determine the incidence and types of nerve injuries in newborns over a ten-year period.
• To identify risk factors associated with obstetric nerve injuries.
• To evaluate the outcomes and potential for residual defects in affected infants.

Main Methods:

• Retrospective analysis of 32,637 deliveries over ten years.
• Data collection on nerve injury incidence, type, and affected nerve (brachial plexus, facial nerve).
• Statistical analysis to identify risk factors such as antenatal care, macrosomia, delivery type, and maternal parity.

Main Results:

• Overall nerve injury incidence was 1.81/1000 deliveries.
• Brachial plexus (1/1000) and facial nerve (0.74/1000) injuries constituted 98% of cases.
• Lack of antenatal care, macrosomia, abnormal presentations, and operative vaginal deliveries were significant risk factors.
• Injuries occurred even in C-sections for obstructed labor; no residual defects were noted in followed-up cases.

Conclusions:

• Obstetric nerve injuries, particularly brachial plexus and facial nerve palsies, are associated with specific risk factors.
• Timely detection of cephalopelvic disproportion and abnormal lie can significantly reduce the incidence of these injuries.
• Effective management and intervention are key to preventing long-term neurological deficits in newborns.
