Objective To investigate the effect of preoperative anemia on postoperative outcome of acute craniocerebral patients undergoing intraoperative blood exchange. Methods A retrospective analysis was conducted on 297 patients who were admitted to our hospital from January 2019 to March 2023 for intraoperative blood transfusion, and 168 patients were included in this study. All patients were divided into anemia group (n=120) and non-anemia group (n=48) according to whether they were anemic before surgery. The clinical data, intraoperative blood transfusion, postoperative hospitalization days, in-hospital mortality and other related data of the two groups were analyzed in detail. Results The incidence of anemia in patients with acute craniocerebral surgery was 16.16%. There were significant differences between the two groups in intraoperative blood loss, red blood cell transfusion, platelet count 24 hours after surgery and other indicators (P<0.05). There were no significant differences between the two groups in postoperative hospitalization days and postoperative ICU stay (P>0.05). Compared with the non-anemia group, the hospitalization mortality in the anemia group was significantly higher, with significant differences. P<0.05. Conclusion The in-hospital mortality of patients with acute craniocerebral transfusion is affected by preoperative anemia, cerebral hernia and other related factors. If the patient has preoperative anemia symptoms, the amount of intraoperative blood transfusion and red blood cell transfusion will be significantly increased, and the length of ICU stay and postoperative hospitalization will not be significantly changed.
