Filter by:Although blood transfusion is a representative treatment for acute anemia due to blood loss during surgery, it is also a powerful risk factor for postoperative cognitive dysfunction. 'Restrictive transfusion', which transfusions minimal red blood cells, is not only useful for conserving limited blood resources, but also does not worsen prognosis or mortality after surgery. Research has also been reported that severe restrictive transfusion has improved prognosis and mortality. However, anemia is also one of the risk factors for postoperative complications, including neurocognitive impairment, it is still controversial how much anemia should be allowed in elderly people who are sensitive to ischemia or heart disease. The purpose of this study is to determine whether the restrictive transfusion policy reduces the frequency of postoperative cognitive dysfunction than the liberal transfusion policy in patients aged 65 years or older who undergo lumbar interbody fusion. Restrictive transfusion strategy (which initiates transfusion when hemoglobin level is less than 8 g / dL during perioperative period) // liberal transfusion strategy (which initiates transfusion when hemoglobin level is less than 10 g / dL during perioperative period)
This study use Loewenstein cognitive function rating scale to meet the standards of the elderly cognitive function assessment. POCD diagnostic criteria used is the recommended value Z current international law, in order to reduce the effects of exercise, we selected 50 cases of patients with age-matched healthy control group as a spouse, the same scale testing. And Loewenstein Assessment Scale cognitive function after some domestic research proved to have good sensitivity, and easy to test small changes in cognitive ability. Before the investigation began strict inclusion and exclusion criteria, the use of simple intelligence scale exclude preoperative cognitive decline in the elderly significantly, the use of depression rating scale for anxiety rating scale before surgery to exclude severe depression and severe anxiety in elderly self self patient. Testing by the same person in the same way neurocognitive assessment test twice, 7 days apart. Studies in Chinese population, susceptibility SNPs and genetic POCD but there are few reports of this project uses 1: 1 matched case-control study, by comparison POCD SNPs and control groups of different polymorphisms, polymorphisms Discussion Han population of postoperative cognitive dysfunction associated with susceptibility to find Chinese Han population of postoperative cognitive disorders genetic susceptibility markers, which provide scientific screening and early diagnosis of postoperative cognitive impairment at high risk in accordance with
