Relationship between postoperative delirium and reduced brain oxygen saturation in elderly heart surgery patients

The relationship Between Postnyn Delirium and Postnum Cerebral Oxygen Desaturation in Older Patients After Stalking Surgerybackground and objective
hypothalamus reduction inis associated with neurological complicationsWe use the near-infrared spectrum to measure local brain oxygen saturation non-invasivelyThe study looked at whether the decrease in brain oxygen saturation in elderly patients after heart surgery was associated with postoperative neurological complicationswe included patients 70 and older planning for heart surgery in a single-center, forward-looking, observational study between2015 and 2017The basic value of oxygen saturation in all patients was measured the day before surgeryIn surgery and ICU continuousmonitoring of the patient's brain oxygen saturation to 72h after surgeryuse the ICU Patient Awareness Fuzzy Assessment Form (Confusion assessment method for the ICU, CAM-ICU) to assess delirium,using non-corrective analysis and multivariate Logistic regression analysis to evaluate its relevance to deliriumResultsa total of 103 patients were included in this prospective observational study, excluding patients who did not meet the conditions of a total of 96 patients were included in the data analysis, of which 29 (30%) patients developed postoperative deliriumThere was no significant correlation between the decrease of brain oxygen saturation in surgery and postoperative delirium Compared with the patients without delirium, the minimum brain oxygen saturation is lower after operativeness, and the absolute value of brain oxygen saturation is more obvious after operative patients, and other differences between patients are not obvious after the factor of brain oxygen saturation is excluded The advanced age, stroke history, higher EuroSCORE II score, preoperative MMSE score is lower
, postoperative more obvious absolute decrease in brain oxygen saturation is independently related to the occurrence of postoperative delirium concluding Postoperative delirium in elderly patients who underwent in vitro circulatory heart surgery was associated with reduced brain oxygen saturation, especially after the onset of delirium original literature abstract
