“…9 Only very few studies were performed to assess the benefit of ANH or ICS in scoliosis surgery, and the results were conflicting. [10][11][12][13][14] In this prospective randomized study, we compared the perioperative hemoglobin levels in patients who had both the ANH and ICS technique against those who only had ICS technique during PSF surgery.…”

Background: Massive blood loss during posterior spinal fusion for adolescent idiopathic scoliosis remains a significant risk for patients. There is no consensus on the benefit of acute normovolemic hemodilution (ANH) or intraoperative cell salvage (ICS) in scoliosis surgery. Methods: Patients were randomized to one of two groups. Group A received ANH and ICS during operation, while group B received only ICS. Patients' age, sex, height, weight, body blood volume, number of fusion level, Cobb angle, number of screws, duration of surgery, and skin incision length were recorded. Hemoglobin and hematocrit levels were obtained preoperatively and postoperatively (0 h and 24 h). Results: There were 22 patients in each group. There was no significant difference in total blood loss. The perioperative decrease in hemoglobin levels between preoperation and postoperation 24 h (group A 2.79 + 1.15 and group B 2.76 + 1.00) showed no significant difference (p ¼ 0.93). Group A observed a larger decrease in hemoglobin levels at postoperative 0 h relative to preoperative level (2.57 + 0.82 g/dl), followed by a smaller decrease within the next 24 h (0.22 + 1.33 g/dl). Group B showed a continued drop in hemoglobin levels of similar magnitude at postoperation 0 h (1.60 + 0.67 g/dl) and within the next 24 h (1.16 + 0.78 g/dl). One patient from group B received 1 unit of allogenic blood transfusion (p ¼ 0.33). Conclusions: The addition of ANH to ICS in posterior spinal fusion surgery for AIS resulted in a similar decrease in hemoglobin levels between preoperative values and at 24 h postoperatively.

“…Other researchers 6 have evaluated the benefit of IBS in surgery for scoliosis comparing two groups; one with 58 patients, in which this method was used, and another with 37 patients in which it was not used. Those authors found that the volume of blood that needs to salvaged by IBS to justify its use in surgery is at least 500 ml.…”

Objective: To evaluate the effectiveness of intraoperative blood salvage (IBS) in reducing allogeneic transfusion in patients undergoing surgery for scoliosis. Methods: Retrospective case-control study with 69 patients who underwent surgical treatment for scoliosis correction from August 2008 to December 2014 in a teaching hospital. We used the IBS in 43 patients and it was not used in 26. The groups were compared according to the medical records, and the data were processed on SPSS 20.0. For the associations between the variable IBS and non-IBS and the independent variables we applied the χ 2 and the likelihood ratio tests, and the strength of which was calculated by their 95% CI. The means were compared by Student's t and Mann-Whitney tests. The confidence level was 0.05. Results: There were no significant differences between groups with the variables age, sex, preoperative weight, postoperative blood drainage and surgical time. There was a significant reduction of intraoperative allogeneic transfusion in the IBS group submitted to posterior arthrodesis compared with the control group, with no difference in the transfusion of red blood cells between the two groups postoperatively. In the 24 patients who underwent combined arthrodesis, there was no significant difference in allogeneic transfusion in the intra-and postoperative periods between the groups. Conclusion: The system proved to be effective in reducing allogeneic transfusion during surgery in patients undergoing posterior arthrodesis for scoliosis, but it was not effective in reducing allogeneic transfusion in the intra-and postoperative periods of those undergoing combined arthrodesis.Keywords: Spinal fusion; Scoliosis; Blood transfusion, autologous; Operative blood salvage; Erythrocytes. RESUMO

“…At our and other institutions, at least 250 cc of blood must be collected to wash and process the blood for approximately a third of its return to the patient. There has been controversy regarding its "added value" [12][13][14] due to these minimum blood loss requirements, as well as inconsistencies in reports on cell saver reducing the rate of transfusion. However, these studies referred to more limited lumbar procedures, in contrast to the more extensive posterior spinal fusion performed in our series of scoliosis cases, which involved an average of 11.5 levels and longer operative times with higher risk of increased blood loss, in a population in which blood transfusion was not an option.…”
