A
5.6-KG term neonate
was born via spontane-
ous vaginal delivery compli-
cated by shoulder dystocia;
Apgar scores were 5 and 7
at 1 and 5 min. e neonate
received continuous positive
airway pressure for respira-
tory distress, developed cervi-
cal emphysema, and then was
intubated because of hypox-
emia. Although capnogra-
phy appeared to indicate a
successful intubation, breath
sounds were undetectable by auscultation. Chest tubes were placed after a radiograph showed bilateral pneumothoraces.
e neonate arrived at our institution in extremis (heart rate, 59 beats/min; mean arterial pressure, 50 mmHg; SpO
2
, 62%).
Venoarterial extracorporeal membrane oxygenation was initiated via the right internal jugular vein and the right internal
carotid artery. Computed tomography showed absent lung aeration, the arterial cannula (fig. 1A, ac), subcutaneous emphy-
sema (fig. 1A, white arrows), and the endotracheal tube diverging from the midline (fig. 1A, black arrows). Bronchoscopy by
the otorhinolaryngologist confirmed a laryngeal tear with a ruptured anterior commissure (fig. 1B, asterisks) through which
the endotracheal tube traveled into the mediastinum. e otorhinolaryngologist repositioned the endotracheal tube into the
native trachea (fig. 1B). Support was withdrawn 6 days later after progression of hypoxic ischemic injury. Autopsy findings
included a hypoplastic thyroid cartilage that likely resulted in an inherent weakness of the anterior tracheal wall.
Traumatic delivery and endotracheal intubation can cause life-threatening tracheal and laryngeal injuries in neonates.

Develop-
ment of cervical emphysema before intubation suggests that this child’s laryngeal rupture was caused by a difficult delivery rather
than traumatic intubation. Fiberoptic endoscopy should be used to investigate potential airway rupture, with emergent otorhinolar-
yngology consultation and deferral of endotracheal intubation until direct airway visualization has been accomplished.

Extracorpo-
real membrane oxygenation should be considered early if direct airway visualization cannot be performed.
