Differentiaaldiagnose bij patiënten bij wie een anoxisch-ischemisch coma wordt vermoed

Three case studies illustrate that suspected anoxic-ischaemic coma often requires careful differential diagnosis to detect treatable conditions. A 47-year-old man underwent cardiopulmonary resuscitation for ventricular fibrillation caused by myocardial ischaemia. He exhibited rhythmic eyelid movements while in a coma. Epilepsy was suspected, and the patient regained consciousness after being treated with antiepileptic drugs. A 34-year-old man underwent cardiopulmonary resuscitation for multiple episodes of ventricular fibrillation. Treatment was directed toward myocardial ischaemia and included anticoagulants. The patient had bilateral, fixed dilated pupils. A CT of the brain showed traumatic contrecoup haemorrhage in the left temporal lobe with signs of transtentorial herniation. The patient died. A 74-year-old woman was found unconscious at home. An ECG performed by the paramedics showed ST segment elevation in the precordial leads. Anoxic-ischaemic coma following cardiac arrest was suspected. However, a coronary angiogram was normal and a CT of the brain revealed subarachnoid haemorrhage caused by a ruptured intracranial aneurysm. She recovered after cranial surgery.
