Capital Medical University30 enrolled

Overview

This was a single-center, observational study. Patients with successful cardiopulmonary resuscitation (CPR) will be transferred to the emergency intensive care unit for further standardized management. After successful return of spontaneous circulation (ROSC) for 72 hours and hemodynamic stability for 24 hours, the patients underwent positron emission computed tomography (PET-CT) examination after resuscitation. The supervising physician accompanied the patient and used monitors to monitor vital signs during the examination. Patients who were on ventilators were mechanically ventilated with a magnetic ventilator (HAMILTON-MRI, United States). In addition to conventional cerebral oxygen metabolism, cerebral blood flow, oxygen extraction fraction, cerebral blood volume and other indicators were added in this experiment. These indicators can evaluate the patient's cerebral metabolism, cerebral blood flow and cerebral blood oxygen damage degree. The neurological outcome was followed up 6 months after onset according to the cerebral performance category（CPC）.

Outcomes

Primary Outcomes

Neurologic prognosis

Patients will be followed up for neurologic prognosis according to the Cerebral Performance Category Scale（CPC）at 6 months after disease onset.The CPC score was divided into five grades. Grade 1 represented intact brain function, the patient was awake and alert, and had the ability to live and work normally. Grade 2 represents moderate cerebral disability, in which the person is awake and able to work part of the time in a specific environment or perform daily activities independently; Grade 3, severe cerebral disability: the person is awake but dependent on others for daily assistance and retains limited cognition; Grade 4 represents coma and vegetative state, the patient is unconscious, unconscious to the environment, and has no cognitive ability; Level 5 represents death, with the patient confirmed as brain death or death by traditional criteria. According to the CPC score, grade 1-2 was defined as good neurological outcome, and grade 3-5 was defined as poor neurological outcome.
