Quantitative estimation of intraoperative blood loss volume in surgical correction of idiopathic ... more Quantitative estimation of intraoperative blood loss volume in surgical correction of idiopathic scoliosis with patient's positioning ensuring complete decompression of the anterior abdominal wall. Material and Methods. Results of surgical correction of idiopathic scoliosis in 122 patients who underwent surgery involving skeletal traction and posterior correction with hybrid instrumentation in the prone position were analyzed. Posterior correction in 60 patients from Group I was performed on a standard orthopedic table, and in 62 patients from Group II-on a modular operating table for spinal surgery providing complete decompression of the anterior abdominal wall. Results. The studied parameters in groups were as follows: deformity magnitude-54.7° ± 16,3° in Group I vs 61.5° ± 19.4° in Group II, the length of the posterior spinal fusion-12.5 ± 1.1 vs 12.8 ± 0.9 segments, the number of levels in transpedicular fixation-4.1 ± 1.1 vs 4.2 ± 1.8, and surgery duration-169.4 ± 30.3 min vs 159.0 ± 31.6 min, respectively. The volume of intraoperative blood loss showed significant difference between groups: 1024.9 ± 409.2 ml (28.6 ± 12.3 % of circulating blood) in Group I, and 595.2 ± 208.6 ml (16.7 ± 6.2 % of circulating blood) in Group II. Conclusion. Complete decompression of the anterior abdominal wall during surgical correction of idiopathic scoliosis allowed reducing intraoperative blood loss by 41.6 % and ensuring the absence of indications for blood transfusion in 48.4 % of operated patients.

To perform quantitative assessment of intraoperative blood loss volume and severity during stages... more To perform quantitative assessment of intraoperative blood loss volume and severity during stages of idiopathic scoliosis surgical correction. Material and Methods. Data of intraoperative blood loss during stages of surgical correction of idiopathic scoliosis were analyzed in 1241 operated patients. Multi-stage surgical interventions were performed in 581 (46.8 %) patients, posterior fusion-in 660 (53.2 %), and multilevel corrective vertebrectomy-in 72 (12.4 %) patients. Two methods of general anesthesia were used: TIVA with propofol, fentanyl, tracrium, and with inhaled sevoflurane, fentanyl, and tracrium. Volumes of intraoperative blood loss were assessed at main stages of surgery. Results. Total intraoperative blood loss during multistage surgical treatment with segmental hook instrumentation was 967.4 ± 43.6 ml, and with hybrid instrumentation-1135.9 ± 139.5 ml. Blood loss during posterior only fusion procedure was 865.5 ± 40.1 ml with segmental hook instrumentation, and 1049.9 ± 75.5 ml with hybrid instrumentation. Multilevel vertebrectomy was associated with maximum intraoperative blood loss of 1242.9 ± 121.8 ml. Conclusion. Intraoperative blood loss during surgical correction of idiopathic scoliosis varies considerably and averages from 20.0 to 40.0 % of the circulatory blood volume. The duration of surgical intervention is the main proved factor influencing the volume of blood loss.
