عنوان انگلیسی Predictive Factors of Hospital Stay and Blood Loss in Minor Lumbosacral Surgery: Multi-Centric, Prospective, Cross-Sectional Survey
چکیده انگلیسی مقاله Background: The aim of this study was to determine predictive factors of blood transfusion and the length of hospital stay in patients who underwent spinal surgery that required discectomy or decompression with laminectomy, without segmental instrumentation. Materials and Methods: The purpose of this multi-center, prospective cross-sectional survey study was to determine predictive factors of blood transfusion and the length of hospital stay in 252 adults’ patients who underwent spinal surgery that required discectomy or decompression with laminectomy, without segmental instrumentation. Descriptive analysis, univariate and multivariate analysis were used to describe the predictive factors of blood transfusion requirement and the length of hospital stay (LOS). Results: According to our statistical analysis the length of operation (R2: 0.65 and p< 0.001) and the volume of intra-operative blood loss (R2: 0.66 and p=0.033) significantly predict the postoperative LOS in patients who had had the lumbar discectomy. Additionally major predictors for intra-operative blood loss were the length of operation (R2:0.30 and p< 0.001) and much more comorbid conditions (R2:0.34 and p=0.002).The considerable predictors for postoperative LOS in patients who had had laminectomy without instrumentation were the length of the operation (R2: 0.34 and p< 0.001), perioperative blood loss (R2: 0.44 and p=0.042) and also age >50 (R2: 0.42 and p< 0.001). As well, the length of operation (R2: 0.27 and p< 0.001), mean of perioperative systolic blood pressure (R2: 0.31 and p< 0.001) and the co-morbidities (R2: 0.42 and p< 0.001) were the significant predictors for perioperative blood loss.Conclusion: In order to our study, in discectomy and laminectomy without instrumentation, length of operation and the volume of perioperative blood loss seem to be the significant predictors for length of hospital stay.
