Overview
Phrenic nerve paralysis, a rare complication of birth trauma, can lead to diaphragmatic dysfunction. This can manifest as respiratory distress in neonates due to the inability of the diaphragm to contract properly.Diagnosis
Diagnosis is often suspected based on clinical presentation of respiratory distress and unilateral absence of diaphragmatic movement on imaging 1.
Diaphragmatic excursion can be assessed via fluoroscopy or ultrasound 1.
Electromyography (EMG) can confirm phrenic nerve dysfunction 1.Management
Management is primarily supportive and depends on the severity of respiratory compromise 1.
Mild cases may resolve spontaneously with observation 1.
Severe cases may require mechanical ventilation 1.
Surgical plication of the diaphragm can be considered for persistent, symptomatic paralysis 1.Special Populations
Neonates are the primary population affected by phrenic nerve paralysis as a birth trauma 1.Key Recommendations
Diagnosis of phrenic nerve paralysis should be considered in neonates with unexplained respiratory distress and unilateral diaphragmatic paralysis 1. (Evidence: Expert opinion)
Diaphragmatic excursion should be assessed using imaging modalities such as fluoroscopy or ultrasound 1. (Evidence: Expert opinion)
Management should be tailored to the severity of respiratory compromise, ranging from observation to mechanical ventilation 1. (Evidence: Expert opinion)
Surgical diaphragm plication may be an option for neonates with persistent, symptomatic phrenic nerve paralysis 1. (Evidence: Expert opinion)References
