Blood Loss Volume

Introduction: Surgical correction of adolescent idiopathic scoliosis is inevitably accompanied by blood loss. About 37–85% of patients undergo allogeneic transfusions associated with a risk of serious complications. Prediction of the expected blood loss volume remains a topical problem. In this regard, there is a need to clarify predictors of increased blood loss. Aim: To assess the effect of vertebrectomy on the intraoperative blood loss volume during surgical correction of adolescent idiopathic scoliosis. Materials and methods: A retrospective study included 511 adolescents who underwent posterior correction of spinal deformity. Two groups were allocated: Group I consisted of 303 patients who underwent multilevel transpedicular fixation; Group II included 208 patients who underwent multilevel transpedicular fixation combined with Smith-Peterson osteotomy. Results: Intergroup comparisons revealed significant differences in the number of transpedicular fixation levels and the volume of blood loss, which were higher in Group II. After aligning the groups by the number of transpedicular fixation levels using the Propensity Score Matching method, no statistically significant difference was observed. We derived formulas for calculating the expected blood loss volume in Groups I and II. Comparison of the formulas revealed that the formula for Group II predicted a significantly lower volume of blood loss, by 2.51%, while the formula for Group I predicted a significantly higher volume of blood loss, by 3.27%. In our opinion, application of the formula that overestimates expected intraoperative blood loss is most reasonable due to a possibility of the worst case scenario during surgery; therefore, the formula for Group I approaches a universal model for use. Conclusion: Smith-Peterson osteotomy did not affect the amount of blood loss during surgical correction of adolescent idiopathic scoliosis, considering the number of transpedicular fixation levels.

Abstract Background Adolescent idiopathic scoliosis (AIS) is a common spinal deformity. Posterior spinal fusion remains an important surgical treatment for AIS. This study aims to determine the predictive factors for intraoperative blood loss in AIS surgery. Methods Patients who had undergone posterior spinal fusion for adolescent idiopathic scoliosis in a single university hospital were reviewed over a 7-year period. Predictive factors for intra-operative blood loss were studied by multivariate analysis to derive a regression model. Receiver operating characteristic analysis was performed to determine the cut-off values of factors contributing to significant intraoperative blood loss (≥500 ml). Results Two hundred and twelve patients were included. Intraoperative blood loss was found to be correlated with gender (rs = 0.30 (0.17–0.43)), preoperative hemoglobin level (rs = 0.20 (0.04–0.31)), preoperative Cobb angle (rs = 0.20 (0.02–0.29)), number of fused levels (rs = 0.46 (0.34–0.58)), operation duration (rs = 0.65 (0.54–0.75)), number of anchors (rs = 0.47 (0.35–0.59)), and p-value ranged from < 0.001 to < 0.05. Significant intraoperative blood loss was influenced by the male gender, operation duration greater than 257.5 min and more than 10 anchors used. Conclusions Male gender, increased operation duration and higher number of anchors predicted higher intra-operative blood loss.

Background. In surgical treatment of adolescent idiopathic scoliosis (AIS), hybrid universal clamp system has been used by some authors. We aimed to compare the clinical and radiologic outcome of hybrid universal clamp with hybrid thoracic hook lumbar screw. Methods. A prospective study was performed on 56 consecutive patients with AIS, who had alternatively undergone a posterior spinal fusion and instrumentation with hybrid thoracic hook lumbar screw system (28 patients: group A) and hybrid universal clamp system (28 patients: group B) between June 2006 and January 2014 at Imam Reza University Hospital and had been followed up for more than two years. The comparison was according to radiographic changes, operative time, intraoperative blood loss, complications, and Scoliosis Research Society (SRS-22) outcome scores. Results. The preoperative mean curve Cobb angle was 58°±7° (42°–74°) in group A and 60°±9° (46°–75°) in group B. The mean final coronal curve correction was 60.4% and 75.5% in groups A and B, respectively (P=0.001). Postoperative SRS outcome scores were also comparable. Conclusion. Universal clamp instrumentation had a significantly better curve correction and lower complication rate compared with hybrid thoracic hook lumbar screw. Both instrumentation methods had similar operative time, intraoperative blood loss, and postoperative SRS outcome scores.

Abstract BACKGROUND: Sixty percent of paragangliomas are located unilaterally at the carotid bifurcation. These are referred to as carotid body tumors (CBTs). OBJECTIVE: To present our 10-year experience in the management of patients with CBTs, and to evaluate the efficacy of angiography and preoperative embolization technique in this retrospective study. METHODS: Sixty-two patients with surgically removed CBTs (Shamblin class II and III), were divided into two groups. Group I, the preoperative embolization group, included 33 patients with 11 class II lesions and 25 class III lesions. Group II, the group that had surgery only, without preoperative embolization, included 29 patients with 9 class II lesions and 21 class III lesions. Comparisons were made between the groups in terms of mean intraoperative blood loss, mean operation time, mean postoperative hospital stay, and clinical complications. RESULTS: In group I, post-embolization angiography demonstrated complete tumor devascularization in 25 (76%) lesions and partial devascularization in 11 (24%) lesions. All but 1 (2%) lesion were completely excised. Mean intraoperative blood loss, mean operation time, and mean hospital stay were 354.8 ± 334.4 mL, 170.3 ± 75.4 min, 8.0 ± 2.1days in group I and 656.4 ± 497.4 mL, 224.6 ± 114.0 min, 9.5 ± 3.5days in group II, respectively. In group II, 27 lesions (91%) were completely removed. The transient ischemic attack (TIA) and cranial nerve injury incidence rates were 10.3% and 13.8% in group II and only 3% for TIA in group I. CONCLUSION: These results suggest angiography is highly valuable for the diagnosis of CBT. Preoperative selective embolization of CBT is an effective and safe adjunct for surgical resection, especially for Shamblin class II and III tumors.

Background: Herniated lumbar disc is a common cause of lumbosacral pain. Endoscopic interlaminar lumbar discectomy (ILD) is a well-established technique that provided comparable results to micro-discectomy. The aim of the study is to describe the learning curve of endoscopic ILD and explore measures that could improve effectiveness and decrease blood loss and operative time with accumulation of reasonable experience. Methods: This retrospective cohort study included 65 patients presenting with symptomatic herniated lumbar disc who underwent endoscopic ILD. Patients were divided into two groups: Group I (standard technique) and Group II (modified technique). Collected data included patients’ age, gender, preoperative manifestations, visual analog score (VAS) for pain, Oswestry Disability Index (ODI), disc level, operative time, intraoperative blood loss, complications, and follow-up data at 1, 6, and 12 months postoperatively. Primary outcomes included total operative time, amount of intraoperative blood loss, and post-operative improvement in pain. Secondary outcomes included intraoperative complications, rate of conversion to open surgery, and recurrence. Results: Post-operative VAS and ODI improved significantly in both groups. Mean total surgical time and intraoperative blood loss were significantly lower in Group II compared to Group I (P < 0.001). The learning curves for operative time and intraoperative blood loss were shallow in Group I, and almost flattened in Group II. Complications were recorded in only three cases, and no symptomatic recurrences were reported. Conclusion: The learning curve of endoscopic ILD was shallow with standard technique, indicating difficulties in mastering the procedure. The proposed modified technique helped reaching the required level of proficiency in the early phase of the curve, providing a significant reduction in operative time and blood loss, with comparable effectiveness and safety as the standard technique.

Objective: The aim of this study is to determine the efficacy of preoperative misoprostal in reducing hemorrhage during abdominal myomectomy. Study Design: Prospective comparative randomized double blinded Place and Duration: Conducted at DHQ Zanana hospital Dera Ismail Khan for one year duration from January 2019 to December 2019. Methods: Total 100 patients underwent abdominal myomectomy were presented in this study. Patients were aged between 18-45 years of age. Patients’ detailed demographics including age, body mass index and parity were recorded after taking informed written consent. Patients were categorized equally into two groups, I and II. Group I had 50 patients and received single dose 400 micrograms of misoprostol transrectally one hour preoperatively and group II had 50 patients and received 2-tablets of placebo preoperatively. Outcomes intraoperative blood loss, blood transfusion, hysterectomy and complications among both groups were assessed. Complete data was analyzed by SPSS 23.0 version. Results: Mean age of the patients was 32.16±9.44 with mean BMI 26.07±10.44 kg/m2. There were no significantly difference among age and body mass among both groups. 60 Patients had 0 parity, 30 patients had parity 1 and the rest were had parity 2. Mean pre-operative hemoglobin in group I was 13.64±8.55 and post-operative was 9.88±8.55 and in group II mean pre-operative hemoglobin was 13.55±8.55 and post-operative was 9.12±5.55. Mean intraoperative blood loss in group I was 388.17±37.18 ml and in group II was 501.16±17.64 ml. Post-operatively blood transfusion in group I was among 2(4%) cases and 3 (6%) in group II. Mean hospital stay in group II was greater as compared to group I. Nausea, vomiting and shivering were the complications found in this study. Conclusion: We concluded in this study that the use ofmisoprostol preoperatively during abdominal myomectomy was effective safe and useful in reduction of intraoperative blood loss and post-operatively blood transfusion among patients.

Study Design: Prospective randomized clinical trial. Objectives: To assess the effectiveness of PEAK Plasmablade (PPB), compared with bipolar sealer and standard electrocautery, in the posterior spinal instrumentation and fusion (PSF) surgery performed for adolescent idiopathic scoliosis (AIS). Methods: Ninety-three patients undergoing PSF surgery for AIS were randomized in 2 groups: group-A patients (n = 45) underwent PSF surgery using PPB; group-B patients (n = 48) were treated with bipolar sealer and standard electrocautery. Demographic and surgical data was recorded. All the patients underwent serial blood tests on the day before surgery (T0) and at 24 (T1), 48 (T2), 72 (T3), and 96 (T4) hours postoperatively. Visual analogue scale for pain (VAS) score, the percentage of paracetamol assumption, and the blood transfusion rate were recorded in the time-lapse T1 to T4. Intergroup variability was assessed. Pearson correlation test was performed. A P value <.05 was considered significant. Results: In group A, a significantly shorter total operative time ( P = .0087), a significantly lower total intraoperative blood loss (TBL) ( P = .001), and a higher postoperative hemoglobin (Hb) ( P = .01) were recorded. A significant higher mean Hb concentration and mean albumin value was recorded in group A at 24 and 48 hours postoperatively. A significant correlation between TBL and hospital stay was recorded in both groups (group A, P = .00 001; group B, P = .00 006); moreover, in both groups, a significant correlation was observed between TBL and mean VAS at 72 hours postoperatively (group A, P = .0009; group B, P = .0001) and at 96 hours postoperatively (group A, P = .000 044; group B, P = .00 001). Conclusions: PPB reduces the intraoperative blood loss in PSF performed for AIS, thus allowing a patient’s faster recovery.

Post partum hemorrhage (PPH) is defined as the loss of greater than 500ml of blood from the genitaltract in the first 24 hours following delivery. PPH occurs in 2-11% of all deliveries. Objective: To compare the efficacyof misoprostol and ergometrine for the prophylaxis of Post Partum Haemorrhage. Design: Prospective study. Setting:Gynaecology and Obstetrics Department Military Hospital Rawalpindi. Period: From 01 July 2006 to 31 Dec 2006.Patients & Methods: A total of 200 patients were recruited in the study, they were divided in two groups, group – I (n100) included those patients who were administered ergometrine intravenously at the time of delivery of head for theprophylaxis of post partum haemorrhage, Group – 2 (n-100) included those patients who were administered Misoprostol800 microgram per rectally just before the start of cesarean section for the same purpose. Blood loss was calculatedobjectively by squeezing the soaked pads and quantifying the amount of clots in a kidney tray of standard size to beequal to 500ml.Results: In group I (n-100) 15 patients had mild PPH blood loss >500ml, out of them 03 had severePPH requiring bimanual message and 02 patients required blood transfusion, in group II( n-100). 08 patients had PPH,blood loss >500 ml, out of them 01 patient required uterine message and none required blood transfusion. Chi-squaretest was applied to compare the efficacy of the two groups, P>0.05 showed no significant difference in the efficacy ofthe two groups but the side effects were obviously less in the Misoprostol group. No patient in group II had GI symptomswhile 36 patient in group I had retching and, vomiting and 03 patients had raised B.P after the administration ofergometrine. Conclusion: Misoprostol administered per rectally has equal efficacy to ergometrine given intravenouslyfor the prophylaxis of post partum haemorrhage but the side effect profile and patient tolerability is better withMisoprostol.
