The purpose of this study is to investigate the possible relationship of microRNA and postoperative delirium.
Postoperative delirium is one of the most common postoperative complications in elderly patients.It has been shown that postoperative delirium has independent adverse effects on short and long-term mortality and morbidity, including poor functional recovery, postoperative cognitive dysfunction, deterioration in quality of life, and increased costs. However, at the present time, postoperative delirium is a clinical phenomenon, and its neuropathogenesis remains unknown. This gap in knowledge has become a barrier that limits further studies, including the development of potential interventions for postoperative delirium.
Study Type
OBSERVATIONAL
Enrollment
52
Trained clinical research assistants interviewed the patients on the first and second day post surgery. The interview included the Confusion Assessment Method (CAM) and MDAS. CAM is a diagnostic algorithm used to determine the presence or absence of delirium.
The level of microRNA in cerebrospinal fluid and serum
All of the participants had spinal anesthesia for the scheduled surgery. Two milliliter of CSF was collected from a spinal needle by anesthesiologists during the spinal anesthesia before the administration of the local anesthetic. Blood samples were collected from patients prior to spinal anesthesia.
Time frame: through study completion, an average of 1 year
