Why are Patients with Acute Middle Cerebral Artery Infarction Being Intubated?

Abstract

Objective: To describe the causes of intubation in patients who have been diagnosed with middle cerebral artery (MCA) infarction requiring mechanical ventilation (MV) by evaluating the clinical and radiologic features in the neurological intensive care unit (NICU). Materials and Methods: The patients with MCA infarction who required MV in the NICU were evaluated retrospectively. All patients’ age, sex, risk factors of stroke, lesion topography, etiology and treatment of stroke, cause of intubation, percentage of extubation, death/discharge status were recorded. Results: It is found that between June 1st, 2009, and December 31st, 2015, 91 patients with stroke with MCA infarction were mechanically ventilated in the NICU. Fifty patients were intubated with neurologic causes and 40 patients needed intubation due to cardiopulmonary problems. One patient was treated in the NICU after surgery for a diaphragmatic hernia. Conclusion: The patients with MCA infarction who are followed up on a mechanical ventilator have poor prognosis. This group of patients constitutes elderly individuals who are at risk for vascular and organ failure. Their follow-up must be conducted in NICUs.
