Abstract
Background Postoperative cognitive dysfunction (POCD) refers to disorders affecting orientation, attention, perception, consciousness, and judgment that develop after geriatric orthopedic surgery. Cerebral blood oxygen saturation detection is a way to diagnose cerebral oxygen supply during operation. At present, more and more applications are used for early diagnosis of postoperative cognitive function. Therefore, the present study is to analyze the relationship between postoperative cognitive dysfunction and cerebral blood oxygen saturation in elderly orthopedic patients. Methods This study enrolled 90 elderly patients undergoing orthopedic surgery in our hospital. According to the postoperative cognitive dysfunction, they were divided into POCD group (N = 45) and no-POCD (N = 45) group. The cognitive and psychological function and cerebral blood oxygen saturation were analyzed before and 3 months after the operation. Finally, the indicators of cognitive psychological function and the indicators of cerebral blood oxygen saturation are correlated and analyzed. Results Compared with the normal group, patients with cognitive dysfunction at 3 months after surgery time below preoperative rScO2, time below a 10% decrease from preoperative rScO2, CDL preoperative, minimum rScO2 value, and maximum rScO2 value have significant changes. The results of the correlation analysis found that there is also a significant correlation between the postoperative cognitive and psychological function of the patient and the cerebral blood oxygen saturation at 3 weeks after the operation. Conclusion In elderly orthopedic patients, there is a significant relationship between cerebral blood oxygen saturation detection and cognitive function 3 months after surgery.
Highlights
Postoperative cognitive dysfunction (POCD) refers to disorders affecting orientation, attention, perception, consciousness, and judgment that develop after surgery
The 90 selected patients were divided into two groups according to the postoperative cognitive dysfunction, and 45 people were selected in each group
We analyzed the relationship between inoperative cerebral oxygen and degree testing and postoperative cognitive dysfunction and found a clear correlation between the effects of inoperative cerebral oxygenation testing three months after surgery and postoperative cognitive dysfunction
Summary
Postoperative cognitive dysfunction (POCD) refers to disorders affecting orientation, attention, perception, consciousness, and judgment that develop after surgery. Short-term or long-term postoperative cognitive dysfunction (POCD) occurs after surgery in elderly patients [4] This may be related to an increase in endotoxins during surgery, the formation of blood clots, and the release of endotoxins which mean that systemic inflammation plays important role in progress of POCD [5]. The present study is to analyze the relationship between postoperative cognitive dysfunction and cerebral blood oxygen saturation in elderly orthopedic patients. The results of the correlation analysis found that there is a significant correlation between the postoperative cognitive and psychological function of the patient and the cerebral blood oxygen saturation at 3 weeks after the operation. There is a significant relationship between cerebral blood oxygen saturation detection and cognitive function 3 months after surgery
