The VR group used a commercially available VR headset with the HypnoVR application, providing various environments, musical backgrounds, and a guiding voice, while the control group underwent the procedure without VR. Patients with ASA > 3, chronic pain, cognitive issues, and contraindications against VR use were excluded.

However, blood is a scarce resource, and its unavailability has led to the cancellation of many surgeries. This study aims to identify risk factors for perioperative blood transfusion in colorectal surgery, thus providing valuable insights for better blood management and transfusion planning. We conducted a retrospective cohort study of patients who underwent colorectal surgery at King Abdulaziz University Hospital from 2013 to 2022. Data on patient demographics, comorbidities, surgical details, and transfusion outcomes were collected and analyzed. Statistical analyses included logistic regression to identify predictors of transfusion and over-transfusion. We collected data from 434 patients. Women were almost twice as likely (OR = 1.98; 95%CI = 1.35–2.90) as men to receive one or more units of RBCs. Also more likely to be transfused were patients with a higher ASA score; a lower pre-operative serum hemoglobin (Hgb) level; and malignant disease as the reason for surgery (all p < 0.001). On multivariable analysis, receiving a transfusion of packed blood cells (RBCs) was statistically linked to volume of intra-operative blood loss and Hgb level (both p < 0.001); as well as to pre-operative body mass index (BMI), with patients who were under-weight and of normal weight most at risk, and patients with a BMI between 25 and 35 less likely to be transfused. Patients whose pre-operative serum Hgb level was 12 g/dL or higher were more than twice as likely to not receive a transfusion, while those with pre-operative Hgb levels from 8.0 to 9.9 g/dL were three times more likely than not to receive blood, and those with a pre-operative Hgb under 8.0 g/dL almost five times as likely as not. Key risk factors for perioperative blood transfusion in colorectal surgery are preoperative anemia, diabetes, low BMI, and significant blood loss. Addressing these through a multidisciplinary approach and the development of perioperative protocols may reduce transfusion needs. Future prospective studies are needed to validate these findings and refine transfusion risk assessments.","PeriodicalId":19764,"journal":{"name":"Perioperative Medicine","volume":"31 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
