Randomized Controlled Trial Clinical Trial
[Changes in dementia rating scale scores of elderly patients with femoral neck fracture during perioperative period].
We evaluated changes in dementia rating scale scores in the revised version of Hasegawa's dementia scale (HDS-R), and rated dementia, 2 days before and 7 days after surgery in the elderly patients with femoral neck fracture. The 50 patients examined ranged in age from 70 years to 101 years. A perfect score in the HDS-R is 30 points, and a score below 20 points strongly suggests dementia. ⋯ In octogenarian patients, there was a negative correlation between "postoperative score minus preoperative score" and "the number of the days from suffering fracture to surgery". These results showed that general anesthesia is more advantageous than epidural anesthesia from the viewpoint of the intellectual faculty in septuagenarian and octogenarian patients with femoral neck fracture, and it is within the bounds of possibility that the intellectual faculty may decline if an octogenarian patient is operated after a long delay from the occurrence of fracture. To prevent this decline, patients must be operated on as soon as possible.

We aimed to describe the frequency of atelectasis occurring during anaesthesia, to describe the size and pattern of the atelectasis, and to standardise the method of identifying the atelectasis and calculate its area. ⋯ On the basis of the present findings, we defined atelectasis as pulmonary dependent densities with attenuation values of -100 to +100 HU.

Care of patients with subarachnoid haemorrhage caused by ruptured cerebral artery aneurysm requires careful assessment of neurological function and prevention of rebleeding and ischaemia throughout the perioperative period. An understanding of the cerebral protection techniques used during periods of ischaemia or circulatory arrest will assist the provision of optimal conditions for successful surgical treatment of the aneurysm.
