Posttraumatic Tension Pneumocephalus Causing Atropine-Resistant Bradycardia

Abstract

Pneumocephalus is a serious complication following brain trauma. Tension pneumocephalus (TP) is entrapment of a large volume of air in the cranial vault causing mass effect on the brain parenchyma. It is the intracranial counterpart of tension pneumothorax and if neglected, can be life threatening. TP should be timely differentiated from benign pneumocephalus owing to its various nonspecific and lethal complications. Our patient is a 37-year-old male with a history of road traffic accident who presented to our hospital with headache and nasal discharge for the last two days. Computed tomography showed multiple skull fractures and extensive pneumocephalus. His preoperative heart rate was 38 beats per minute that was resistant to pharmacological interventions and required a temporary pacemaker for surgery. He underwent uneventful craniotomy for dura repair and was discharged home with no neurological deficit.
