Efficacy and utility of antifibrinolytics in pediatric spine surgery: a systematic review and network meta-analysis. Neurosurg Rev 2024; 47:177. [PMID: 38644447 DOI: 10.1007/s10143-024-02424-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 01/09/2024] [Accepted: 04/16/2024] [Indexed: 04/23/2024]
Abstract
Antifibrinolytics have gained increasing attention in minimizing blood loss and mitigating the risks associated with massive transfusions, including infection and coagulopathy in pediatric patients undergoing spine surgery. Nevertheless, the selection of optimal agent is still a matter of debate. We aim to review the utility of these agents and compare the efficacy of antifibrinolytics in pediatric and adolescent spine surgeries. A comprehensive search was performed in Scopus, Web of Science, and MEDLINE databases for relevant works. Studies providing quantitative data on predefined outcomes were included. Primary outcome was perioperative bleeding between the groups. Secondary outcomes included transfusion volume, rate of complications, and operation time. Twenty-eight studies were included in the meta-analysis incorporating 2553 patients. The use of Tranexamic acid (RoM: 0.71, 95%CI: [0.62-0.81], p < 0.001, I2 = 88%), Aprotinin (RoM: 0.54, 95%CI: [0.46-0.64], p < 0.001, I2 = 0%), and Epsilon-aminocaproic acid (RoM: 0.71, 95%CI: [0.62-0.81], p < 0.001, I2 = 60%) led to a 29%, 46%, and 29% reduction in perioperative blood loss, respectively. Network meta-analysis revealed higher probability of efficacy with Tranexamic acid compared to Epsilon-aminocaproic acid (P score: 0.924 vs. 0.571). The rate of complications was not statistically different between each two antifibrinolytic agent or antifibrinolytics compared to placebo or standard of care. Our network meta-analysis suggests a superior efficacy of all antifibrinolytics compared to standard of care/placebo in reducing blood loss and transfusion rate. Further adequately-powered randomized clinical trials are recommended to reach definite conclusion on comparative performance of these agents and to also provide robust objective assessments and standardized outcome data and safety profile on antifibrinolytics in pediatric and adolescent pediatric surgeries.

BMC Musculoskelet Disord 2023; 24:686. [PMID: 37644447 PMCID: PMC10463947 DOI: 10.1186/s12891-023-06811-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 08/18/2023] [Indexed: 08/31/2023] Open
Abstract
BACKGROUND Tranexamic acid (TXA) has been widely used in orthopedic surgery, but its efficacy in adolescent scoliosis (AS) surgery remains unclear in the literature. The purpose of this systematic review and meta-analysis is to evaluate the safety and efficacy of TXA compared to placebo treatment during or after AS surgery, by gathering data from randomized both controlled trials (RCTs) and non-RCTs. METHODS English and Chinese electronic databases including PubMed, Web of Science, Embase, Cochrane, CNKI, and Wan Fang database were searched to identify the relevant literature up until August 2022. The primary outcomes were intraoperative blood loss and total blood loss. The secondary outcomes included the need for transfusion, postoperative hemoglobin (Hb) level, and change in Hb level. Stata 17 was used for data analysis and the risk of bias was assessed. We followed the PRISMA checklist to ensure the quality of this article. RESULTS Twelve studies (795 participants) were included in the meta-analysis for intraoperative blood loss during surgery. The results suggest that TXA can reduce the intraoperative blood loss of the patients (MD = -306.40ml, 95%CI = -404.04ml to -208.77ml, p < 0.001). Six studies (2027 patients) were included in the meta-analysis for total blood loss. The pooled result shows that the total blood loss of the TXA group was significantly lower than that of the control group (MD = -779.24ml, 95% CI = -1157.10ml to -410.39ml, p < 0.001). Five studies (419 patients) were included in the meta-analysis for postoperative Hb level and shows a non-significant outcome (MD = 5.09 g/l, 95%CI = 2.92 g/l to 7.25 g/l, p = 0.611). Three studies (268 patients) were included in the meta-analysis for the postoperative Hb level. There is a non-significant decrease in the TXA group (MD = -0.23 g/l, 95%CI = -0.48 g/l to 0.01 g/l, p = 0.319). Eight studies (670 patients) reported data on the need for transfusion after surgery. The overall relative risks (RR) showed a significant difference between the TXA and control group, with a lower risk of transfusion in the TXA group (RR = 0.547, 95%CI = 0.308 to 0.972, p = 0.04). CONCLUSIONS The meta-analysis of the data reveals that TXA usage is associated with a significant reduction in intraoperative and total blood loss, a lower risk of transfusion, and a non-significant change in postoperative Hb levels in AS surgery However, it should be noted that the surgical operation situations varied across different studies. Therefore, further research is required to investigate the effects of TXA on specific subgroups of gender, operation time, and blood transfusion indicators. Overall, our study provides valuable evidence for the clinical management of AS surgery and may inform the development of practice guidelines and protocols for the use of TXA in this setting.

Abstract
BACKGROUND Significant blood loss is still one of the most frequent issues in spinal surgery. There were different hemostatic methods to prevent blood loss during spinal surgery. However, the optimal hemostatic therapy for spinal surgery is controversial. The purpose of this study was to assess the efficacy and safety of different hemostatic therapies in spinal surgery. METHODS Two independent reviewers conducted electronic literature searches in 3 electronic databases (PubMed, Embase, and Cochrane library database) as well as a manual search to identify eligible clinical studies from inception to Nov 2022. Studies that including different hemostatic therapy (tranexamic acid [TXA], epsilon-acetyl aminocaproic acid [EACA], and aprotinin [AP]) for spinal surgery were included. The Bayesian network meta-analysis was performed with a random effects model. The surface under the cumulative ranking curve (SUCRA) analysis was performed to determine the ranking order. All analyses were performed by R software and Stata software. P value less than .05 was identified as statistically significant. RESULTS Finally, a total of 34 randomized controlled trials met the inclusion criteria and finally included in this network meta-analysis. The SUCRA shows that TXA ranked first (SUCRA, 88.4%), AP ranked second (SUCRA, 71.6%), EACA ranked third (SUCRA, 39.9%), and placebo ranked the last (SUCRA, 0.3%) as for total blood loss. The SUCRA shows that TXA ranked first (SUCRA, 97.7%), AP ranked second (SUCRA, 55.8%), EACA ranked third (SUCRA, 46.2%), and placebo ranked the last (SUCRA, 0.2%) for need for transfusion. CONCLUSIONS TXA appears optimal in the reduction of perioperative bleeding and blood transfusion during spinal surgery. However, considering the limitations in this study, more large-scale, well-designed randomized controlled trials are needed to confirm these findings.

The Effect of Tranexamic Acid on Operative and Postoperative Blood Loss in Transforaminal Lumbar Interbody Fusions. World Neurosurg 2022; 166:e443-e450. [PMID: 35840090 DOI: 10.1016/j.wneu.2022.07.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/05/2022] [Accepted: 07/06/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The purpose of this retrospective cohort study was to evaluate the effect of tranexamic acid (TXA) on reducing perioperative blood loss and length of stay after transforaminal lumbar interbody fusion (TLIF). Spine surgery is associated with the potential for significant blood loss, and adequate hemostasis is essential to visualizing crucial structures during the approach and procedure. Although TXA use has been extensively studied in the pediatric and adult spinal deformity literature, there is a dearth of literature on its efficacy in reducing blood loss for patients who undergo 1- to 3-level TLIF. METHODS All patients requiring 1- to 3-level TLIF who received a preoperative loading dose of TXA were grouped and compared with patients who didn't receive TXA. Demographic, surgical, and laboratory values were collected and analyzed. Continuous and categorical variables were analyzed with χ2, Kruskal-Wallis, or analysis of variance tests, depending on normality and data type. Multiple linear regressions were developed to determine independent predictors of the estimated blood loss (EBL), total blood loss, drain output, and length of stay. Statistical significance was set at P < 0.05. RESULTS Patients who received preoperative TXA had more comorbidities (P = 0.006), longer surgery length (P < 0.001), and longer length of stay (P = 0.004). TXA was independently associated with a decreased day 0, 1, 2, and total drain output (P < 0.001, P = 0.001, P = 0.007, P < 0.001, respectively), but was not associated with a change in EBL, total blood loss, or length of stay. CONCLUSIONS The application of preoperative TXA for patients undergoing 1- to 3-level TLIF reduced drain output in the first 2 postoperative days, but it did not affect hospital length of stay, total blood loss, or EBL.

Abstract
Background Topical hemostatic agents are an option for controlling bleeding during cardiovascular surgery. Previous studies comparing topical hemostatic agents in cardiovascular surgery predate the 2012 reformulation of Surgiflo®, which had been re-engineered to increase paste viscosity and thus be more adherent to the bleeding surface. Objective To compare clinical and economic outcomes in patients receiving the current formulation of Surgiflo vs Floseal during cardiovascular surgeries. Methodology A retrospective analysis was conducted using the Premier Healthcare Database. Eligible patients had an inpatient cardiovascular surgery between 1/1/2013 and 6/1/2018, were ≥18 years old and received the current formulation of Surgiflo or Floseal during surgery. Propensity score matching was performed, with exact matching on the surgery year and surgery type (aortic, coronary artery bypass grafting, valve, or other). Descriptive analysis and generalized estimating equations models compared outcomes between the Surgiflo and Floseal groups. Results The matched sample included 5768 patients in each group (mean age: 66.5 years; 66.3% male). In the matched sample, rates of any documented bleeding event were similar in Surgiflo and Floseal groups (6.9% vs 7.2%; P = 0.576). Differences in transfusion rates between patients receiving Surgiflo vs Floseal varied by operational definition and timing of measurement but did not differ by >2 percentage points. Compared to Floseal, patients who received Surgiflo experienced longer surgery duration (306.0 vs 299.4 minutes), lower hospitalization cost ($44,146 vs $46,812), and lower odds of readmission at 30, 60, and 90 days post-discharge (all P < 0.05). Inpatient mortality and LOS were comparable between Surgiflo and Floseal (all P > 0.05). Conclusion In this large study of real-world clinical and economic outcomes after cardiovascular surgery involving the current formulation of Surgiflo vs Floseal, Surgiflo was associated with mostly similar clinical outcomes as compared with Floseal. Differences in selected economic/resource use outcomes were also observed, for which root-cause analysis in future research would be informative.

Abstract
Abstrakt
W ostatnich latach istotnym obszarem zastosowania fibryny stała się inżynieria tkankowa, w której wykorzystuje się naturalne właściwości biostatyczne i bioaktywne fibryny, a także możliwość pułapkowania i wiązania w jej strukturze czynników wzrostu. Fibryna jest najczęściej stosowana w postaci żeli i dysków. Jednak każda postać wskutek pochłaniania wody docelowo przyjmuje postać żelu. Białko to w warunkach in vivo spełnia rolę rusztowania dla komórek, a także może być aplikowane w miejsca trudno dostępne – może wypełniać ubytki tkanek i podtrzymywać tkanki okalające, zapobiegając ich zapadaniu się. Ponadto fibryna hamuje krwawienie i inicjuje proces odnowy, jak również pełni rolę stymulatora wzrostu komórek. Przez modyfikacje struktury fibryny cząsteczkami adhezyjnymi, można przyspieszyć odbudowę prawidłowej struktury tkanek. Jej właściwości strukturalne mogą być także wykorzystywane jako rezerwuar czynników wzrostu i system ich przedłużonego uwalniania. Fibryna jest materiałem biodegradowalnym, umożliwiając skorelowanie ubytku matrycy fibrynowej z odbudową tkanek własnych pacjenta. Wprowadzenie metod druku 3D i elektroprzędzenia umożliwia formulację dopasowanych do uszkodzeń kształtek oraz włóknin bez utraty bioaktywnych funkcji fibryny. Metody te umożliwiają także poprawę właściwości mechanicznych przez otrzymywanie m.in. włóknin fibryny z innymi polimerami, co jest szczególnie uzasadnione w przypadku materiałów stosowanych w odbudowie takich struktur jak ścięgna czy kości. Biotechnologiczna synteza fibrynogenu może w przyszłości uniezależnić pozyskiwanie go z krwi i zwiększyć popularność wyrobów medycznych otrzymywanych z fibryny.

Abstract
The analysis of the mechanisms of the formation of a rare clinical combination of pulmonary embolism (PE) and diffuse alveolar hemorrhage (DAH), which are complications of systemic vasculitis associated with antibodies to the cytoplasm of neutrophils (primarily granulomatosis with polyangiitis), systemic lupus erythematosus and secondary antiphlogistic syndrome primary antiphospholipid syndrome and Goodpastures syndrome. Taking into account the chronological sequence of the occurrence of PE and DAH, 3 variants of the onset of these potentially fatal additions to the underlying disease were considered: the anticipatory DAH development of PE, delayed from DAH PE and joint (within 24 hours) formation of PE and DAH. A review of single descriptions of such a combination of complications of granulomatosis with polyangiitis is carried out, criteria are indicated, a working classification of severity is given and, taking this into account, a modern program of therapy for DAH as an independent event and in combination with PE.

Abstract
STUDY DESIGN Retrospective. OBJECTIVES Evaluate the role and effectiveness of ICS in primary posterior spinal fusion (PSF) for idiopathic scoliosis (IS). Intraoperative cell salvage (ICS) minimizes blood loss and need for allogeneic transfusions. However, it adds substantial charges ($800-1200 US) and may be of less clinical benefit in some PSF for IS. MATERIALS AND METHODS This was a single-hospital, retrospective analysis of 178 consecutive IS cases (10-18 years of age) who underwent primary PSF by a single pediatric spine surgeon. RESULTS Overall, 41% of cases received a mean 167 cc of ICS blood, after a mean EBL of 528 mL (range 200-1800 mL). No blood was returned in 59% of cases, with a mean EBL of 293 mL (range 75-700 mL). Only 6.5% of the entire cohort received > / = 250 cc via ICS, after a mean EBL of 773 mL. A positive correlation exists between EBL and vertebral levels fused, preoperative major Cobb angle, and length of anesthesia (p < 0.001). ICS may be more efficacious at an inflection point of 12 vertebral fusion levels, preoperative major Cobb angles > / = 55°, anesthesia exposure > / = 6 h, and with use of posterior column osteotomies (PCOs) (p < 0.05). In addition, lack of tranexamic acid use lead to greater EBL (p < 0.0001) and ICS volumes (p = 0.008). CONCLUSION The use of ICS in IS patients undergoing PSF resulted in the return of > / = 250 cc of ICS blood (similar volume to one allogeneic unit) in only 6.5% of cases. Charges for ICS set-up and processing of one bowl of ICS is much higher than for one allogeneic unit ($1200 vs. $462 US), hence transfusing lower volumes of autologous ICS blood is not cost-effective for all PSF for IS.

Efficacy of Intravenous Tranexamic Acid in Reducing Perioperative Blood Loss and Blood Product Transfusion Requirements in Patients Undergoing Multilevel Thoracic and Lumbar Spinal Surgeries: A Retrospective Study. Front Pharmacol 2020; 11:566956. [PMID: 33424584 PMCID: PMC7793852 DOI: 10.3389/fphar.2020.566956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 10/15/2020] [Indexed: 11/27/2022] Open
Abstract
Introduction: Acute perioperative blood loss is a common and potentially major complication of multilevel spinal surgery, usually worsened by the number of levels fused and of osteotomies performed. Pharmacological approaches to blood conservation during spinal surgery include the use of intravenous tranexamic acid (TXA), an anti-fibrinolytic that has been widely used to reduce blood loss in cardiac and orthopedic surgery. The primary objective of this study was to assess the efficacy of intraoperative TXA in reducing estimated blood loss (EBL) and red blood cell (RBC) transfusion requirements in patients undergoing multilevel spinal fusion. Materials and Methods: This a single-center, retrospective study of subjects who underwent multilevel (≥7) spinal fusion surgery who received (TXA group) or did not receive (control group) IV TXA at The Ohio State University Wexner Medical Center between January 1st, 2016 and November 30th, 2018. Patient demographics, EBL, TXA doses, blood product requirements and postoperative complications were recorded. Results: A total of 76 adult subjects were included, of whom 34 received TXA during surgery (TXA group). The mean fusion length was 12 levels. The mean total loading, maintenance surgery and total dose of IV TXA was 1.5, 2.1 mg per kilo (mg/kg) per hour and 33.8 mg/kg, respectively. The mean EBL in the control was higher than the TXA group, 3,594.1 [2,689.7, 4,298.5] vs. 2,184.2 [1,290.2, 3,078.3] ml. Among all subjects, the mean number of intraoperative RBC and FFP units transfused was significantly higher in the control than in the TXA group. The total mean number of RBC and FFP units transfused in the control group was 8.1 [6.6, 9.7] and 7.7 [6.1, 9.4] compared with 5.1 [3.4, 6.8] and 4.6 [2.8, 6.4], respectively. There were no statistically significant differences in postoperative blood product transfusion rates between both groups. Additionally, there were no significant differences in the incidence of 30-days postoperative complications between both groups. Conclusion: Our results suggest that the prophylactic use of TXA may reduce intraoperative EBL and RBC unit transfusion requirements in patients undergoing multilevel spinal fusion procedures ≥7 levels.

Abstract
Background: Intraoperative antifibrinolytic drug administration is a safe and effective method of reducing blood loss and allogenic transfusions in patients undergoing spine deformity correction. Aim: This study aimed to compare the effectiveness of two antifibrinolytic drugs tranexamic acid (TXA) and epsilon amino caproic acid (EACA) in reducing peri-operative blood loss and transfusion requirements against a placebo control in patients with idiopathic scoliosis undergoing correction surgery. Setting and Design: This is a prospective, randomized, double-blinded, controlled comparative study. Methodology: Patients in TXA group received 50 mg.kg−1 bolus and 10 mg.kg−1.h−1 infusion as against 100 mg.kg−1 and 10 mg.kg−1.h−1 infusion in EACA group. The placebo group had saline bolus and infusion. Parameters observed included baseline demographic and deformity data, duration of surgery, total peri-operative blood loss, and allogenic packed red cell transfusion requirements. Statistical Analysis: Mean and standard deviation were used to represent the quantitative continuous data, and percentage was used to represent categorical data. The Student's t-test and ANOVA were used to compare means between groups. Bonferroni's multiple comparison test was used to find out the association between categorical variables. Results: A total of 36 patients were enrolled with 12 patients in each group. Peri-operative blood loss was 50.1% lower in patients receiving TXA and 17.7% lower in patients receiving EACA compared with the placebo group. The volume of total packed red cell transfusion was 66.7% lower in patients receiving TXA and 45.6% lower in patients receiving EACA compared with placebo. Conclusion: TXA was more effective in reducing total peri-operative blood loss and allogenic transfusion requirement in idiopathic scoliosis correction surgery compared to EACA.

Abstract
BACKGROUND The prevalence of adolescent idiopathic scoliosis (AIS) in diverse regions of the world has been studied. Access to care varies widely, and differences in disease severity and operative treatment outcomes are not well understood. This study aimed to determine variation in disease presentation and operative complications for AIS patients from an international cohort. METHODS This is a retrospective study carried out at seven surgical centers in the United States (Manhattan and Miami), Ghana, Pakistan, Spain, Egypt, and China. A total of 541 consecutive patients with AIS were evaluated. Preoperative major curve magnitude, operative parameters, and complications were compared among sites using analysis of variance with post hoc tests and Pearson correlation coefficients. Univariate and multivariate forward stepwise binary logistic regressions determined the variables most predictive of complications. RESULTS Countries with lowest-access to care (Ghana, Egypt, and Pakistan) displayed larger curves, more levels fused, longer operative time (OT), and greater estimated blood loss (EBL) than the other countries (p ≤ .001). Increasing curve magnitude was correlated with greater levels fused, longer OT, and greater EBL in all groups (p = .01). In the univariate regression analysis, Cobb magnitude, levels fused, EBL, and OT were associated with complication occurrence. Only OT remained significantly associated with complication occurrence after adjusting for Cobb magnitude, levels fused, and site (odds ratio [OR] = 1.005, 95% confidence interval 1.001-1.007, p = .003). Complications were greatest in Pakistan and Ghana (21.7% and 13.5%, respectively) and lowest in Miami (6.5%). CONCLUSIONS Larger curve magnitudes in the least-access countries correlated with more levels fused, longer OT, and greater EBL, indicating that increased curve magnitude at surgery could explain the difference in operative morbidity between low- and high-access countries. With OT as the prevailing predictive factor of complications, we suggest that increased curve magnitude leads to longer OTs and more complications. A lack of access to orthopedic care may be the largest contributor to the postponement of treatment. LEVEL OF EVIDENCE Level II.

Abstract
Significant blood loss is often seen in orthopedic surgeries, especially complex spinal procedures that constitute long surgical times, large incisions, and rich blood supplies. Tranexamic acid (TXA), a synthetic analog of the amino acid lysine, has proven to be a cost-effective method in decreasing transfusion rates and avoiding complications associated with low blood volume. Recent data on TXA's use in spine surgery suggest that TXA remains both efficacious and safe, although the ideal dosing and timing of administration is still a point of disagreement. The purpose of this study is to review the literature for the use of TXA in spine surgery to better understand its safety profile and ideal dosage. This narrative review on TXA was conducted on prospective orthopedic studies that used TXA in spine deformity surgery. TXA in adult and pediatric spine surgery has decreased intraoperative and postoperative blood loss, decreasing the need for blood transfusions. The most common dose in the literature is a 10 mg/kg loading dose, followed by 1 mg/kg per hour. Although the proper dosing of TXA for spine surgery remains debatable, studies have proven that TXA is effective at reducing blood loss without increasing the risk of thrombotic events.

Abstract
STUDY DESIGN Delphi process with multiple iterative rounds using a nominal group technique. OBJECTIVE The aim of this study was to use expert opinion to achieve consensus on various methods for minimizing blood loss in patients undergoing posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). BACKGROUND DATA Perioperative blood loss management represents a critical component of safely performing PSF in children with AIS. Little consensus exists on ways to mitigate excessive blood loss after PSF. METHODS An expert panel composed of 21 pediatric spine surgeons was selected. Using the Delphi process and iterative rounds using a nominal group technique, participants in this panel were presented with a detailed literature review and asked to voice opinion collectively during three rounds of voting. Agreement >80% was considered consensus. Interventions without consensus were discussed and revised, if feasible. RESULTS Consensus was reached to support 21 best practice guideline measures for perioperative management of blood loss in patients undergoing PSF for AIS. Areas included preoperative assessment and preparation, intraoperative strategies to decrease blood loss, and postoperative transfusion indications. CONCLUSION We present a consensus-based best practice guideline consisting of 21 recommendations for strategies to minimize and manage blood loss during PSF. This can serve to reduce variability in practice in this area, help develop hospital specific protocols, and guide future research.

Abstract
STUDY DESIGN Retrospective review of a prospective adolescent idiopathic scoliosis (AIS) registry. OBJECTIVE To study the evolution of the operative approach, outcomes, and complication rates in AIS surgery over the past 20 years. SUMMARY OF BACKGROUND DATA Surgical techniques in AIS surgery have evolved considerably over the past 20 years. We study the trends in the operative management of AIS over this period and their impact on perioperative outcomes. METHODS A total of 1819 AIS patients (1995-2013) with 2-year F/U were studied. Operative approach, perioperative parameters, major complication rates, and SRS outcomes were assessed. Linear regression was used to assess the trend of changes over 5-year quartiles. RESULTS Mean age at surgery was 14.6 ± 2.1 years, 80.2% were females, and this remained consistent throughout. Operative time, EBL/level, and LOS decreased over the 20 years (P < 0.0001). The use of antifibrinolytic (AF) increased from 6.7% to 68.8% in the past 10 years (P < 0.0001). Number of levels fused increased and LIV was more distal (in relation to stable vertebrae) over time in Lenke 1 and 2 curves (levels fused 7.97-9.94, P < 0.0001 and 9.8-11.0, P=0.0134, respectively). Anterior spinal fusion (ASF) in Lenke 1 curves decreased from 81% in the first quartile to 0% in the last (P = 0.0429). ASF for Lenke 5 curves evolved from 78% in the second quartile to 0 in the last. Thoracoplasty performance decreased from 76% to 20.3% (P = 0.1632). All screw constructs in PSF cases increased from 0% to 98.4% (P = 0.0095). Two-year major complication rates decreased over time (18.7%-5.1%; P = 0.0173). Increased improvement in SRS scores were observed in pain, image, function, and total domains. CONCLUSION Evolution of surgical technique in AIS over the past 20 years has resulted in a cessation of anterior only surgery, increasing use of all screw constructs, less blood loss, greater use of AF, shorter operative times and LOS, lower major complications rates, and greater improvements in SRS scores.

Abstract
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 = 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 = 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.

Abstract
BACKGROUND Reducing perioperative blood loss and the need for transfusions in patients undergoing spinal surgery is especially important for those with neuromuscular disorders. These patients require extensive spino-pelvic exposure and are often medically fragile. We have used Amicar to decrease blood loss since 2001. As an effort to further reduce blood loss and transfusions, we use a bipolar sealer device (Aquamantys) as an adjunct to electrocautery. We present the results of our first 64 neuromuscular patients to show the efficacy of the device. METHODS Using a prospectively maintained database we reviewed the operative time, estimated perioperative blood loss, cell saver use, and intraoperative and postoperative transfusion rate in patients who underwent posterior spinal fusion for neuromuscular scoliosis. Sixty-four patients were identified who fit these criteria since the use of the bipolar sealer device was instituted.We compared these patients with a control group of the preceding 65 patients in whom this device was not used for hemostasis. All patients, including those in the study group, received Amicar (infusion of 100 mg/kg over 15 to 20 min, then 10 mg/kg/h throughout the remainder of the procedure). The surgical technique did not differ between the 2 groups. RESULTS Baseline characteristics between the 2 groups were similar except for the number of patients having an all-screw construct which was larger in the investigational group (25% vs. 8%, P=0.03). There were no significant differences in operative time or duration of hospital stay. Intraoperative blood loss was lower in the study group (741 mL) as compared with the control group (1052 mL, P=0.003). Total perioperative blood loss, however, showed no significant difference. Thirty-five (55%) patients in the study group and 50 (77%) patients in the control group required additional intraoperative or postoperative transfusions (P=0.01). The number of packed red cell units transfused per patient was 0.81 in the study group and 1.57 in the control group (P=0.001). Although the intraoperative cell saver transfusion was same, the total blood volume transfused, which includes cell saver and any other transfusions, was significantly lower in the study group, 425 mL versus 671 mL (P=0.002). CONCLUSIONS Use of a bipolar sealer device in posterior spinal fusion for neuromuscular scoliosis significantly reduced intraoperative blood loss and transfusion rate when compared with a control group in this retrospective review.

Prevalence and Predictors of Pressure Injuries From Spine Surgery in the Prone Position: Do Body Morphological Changes During Deformity Correction Increase the Risks? Spine (Phila Pa 1976) 2017; 42:1730-1736. [PMID: 28368987 DOI: 10.1097/brs.0000000000002177] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
MINI: Pressure injuries are prevalent in patients undergoing spine surgery while prone. Multiple risk factors exist and should be addressed. We found that patients undergoing spinal deformity correction surgery are at unique risk (odds ratio 3.31, P = 0.010) due to body morphological changes occurring secondary to intraoperative changes in spinal alignment. STUDY DESIGN Review of data and prospective study. OBJECTIVE To investigate the prevalence and predictive factors of pressure injuries in spine surgery performed in the prone position, and to determine whether morphological changes and truncal shifts occurring during deformity correction predispose to this complication. SUMMARY OF BACKGROUND DATA Spine surgery performed in the prone position presents the risk of developing pressure injuries. This risk is potentially increased in deformity correction, because it tends to involve more extensive procedures, with associated longer operating times. METHODS Cases of pressure injuries after spine surgery in the prone position were reviewed to ascertain prevalence and determine risk factors. Data including patient factors (age, sex, height, weight, body mass index, American Society of Anesthesiologists grade, comorbidities, Braden scale, neurological status, spinal pathology) and surgical factors (approach, procedure type, number of screws, operated levels, operative time) were collected. Independent risk factors were identified via multivariate analysis. A subsequent prospective analysis of all patients undergoing spinal deformity correction was conducted by performing intraoperative measurements of body morphological changes and shifts in truncal positions. Statistical correlation was performed to determine whether positional shifts cause pressure injuries. RESULTS The prevalence of pressure injuries was 23.0%. Previous skin problems (P = 0.034), myelopathy (P = 0.013), operative time >300 minutes (P = 0.005), and more than four operated levels (P = 0.006) were independent predictors of pressure injuries. Being a spinal deformity patient was also an independent risk factor for developing pressure injuries (odds ratio 3.31, P = 0.010). Significant changes in body measurements during deformity correction were predictive of pressure injuries. CONCLUSION Pressure injuries are prevalent in patients undergoing spine surgery while prone. Future studies should investigate strategies to prevent this complication based on the multiple risk factors identified in the present study. Patients undergoing spinal deformity correction surgery are particularly at risk due to intraoperative body morphological changes. Improved padding methods should be trialed in future studies.

Abstract
INTRODUCTION Recent healthcare reforms have raised the importance of cost and value in the management of disease. Value is a function of benefit and cost. Understanding variability in resources utilized by individual surgeons to achieve similar outcomes may provide an opportunity for cutting costs though greater standardization. The purpose of this study is to evaluate differences in use of implants and hospital resources among surgeons performing adolescent idiopathic scoliosis (AIS) surgery. METHODS A multicenter prospective AIS operative database was queried. Patients were matched for Lenke curve type and curve magnitude, resulting in 5 surgeons and 35 matched groups (N = 175). Mean patient age was 14.9 years and curve magnitude 50°. Parameters of interest were compared between surgeons via ANOVA and Bonferroni pairwise comparison. RESULTS There was no significant difference in percentage curve correction or levels fused between surgeons. Significant differences between surgeons were found for percentage posterior approach, operative time, length of stay (LOS), estimated blood loss (EBL), cell saver transfused, rod material, screw density, number of screws, use of antifibrinolytics, and cessation of intravenous analgesics. Despite differences in EBL and cell saver transfused, there were no differences in allogenic blood (blood bank) use. CONCLUSION Significant variability in resource utilization was noted between surgeons performing AIS operations, although radiographic results were uniform. Standardization of resource utilization and cost containment opportunities include implant usage, rod material, LOS, and transition to oral analgesics, as these factors are the largest contributors to cost in AIS surgery.

Abstract
BACKGROUND Pre-donation of autologous blood prior to spine fusion for adolescent idiopathic scoliosis (AIS) has been used in deformity surgery. The effect of pre-donation on pre-operative hematocrit (Hct) remains debated. Multiple factors may influence pre-operative Hct including intravascular volume status, patient factors, and timing of pre-operative blood donation. The purpose of this study was to determine if pre-donation significantly lowers pre-incision Hct in AIS patients. METHODS A retrospective cohort study of a Level-1 prospective randomized trial was conducted. 125 patients from the homogeneous population were included. AIS patients undergoing a posterior only spinal fusion for AIS were separated into two groups based on their pre-operative blood donation history. Demographic variables, pre-incision Hct, and transfusion rates were compared between the two groups using the Student's T-test. RESULTS Pre-donation and non pre-donation groups had 28 and 97 patients, respectively. Pre-donation group was 75% female (21F, 7M) and non pre-donation group was 78% female (76F, 21M). There was no difference between pre-donation and non pre-donation groups in mean age (15.6 ± 2.2 vs 14.8 ± 2.2, p = 0.081), BMI (23.1 ± 4.2 vs 21.7 ± 5.3, p = 0.219), and pre-incision Hct (32.8 ± 3.4 vs 33.8 ± 3.1, p = 0.628). The overall transfusion rates were equivalent (32.1± 48.0% vs 25.8 ± 44.0%, p = 0.509), however, the rate of allogenic transfusion for the pre-donation group was significantly lower (3.6 ± 18.9% vs 25.8 ± 44.0%, p = 0.011). CONCLUSIONS This study supports the use of pre-donation for AIS, without a significant drop in pre-incision Hct. Patients that donate are also much less likely to be exposed to allogenic blood. There may be a surgeon bias to recommend pre-donation in patients with a larger BMI and older age. Future studies are needed from a larger population of patients including those with non-AIS pathology. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND This is an updated version of the original Cochrane review first published in 2008. Scoliosis surgery is often associated with substantial blood loss and potentially detrimental effects in children. Antifibrinolytic agents are often used to reduce perioperative blood loss. Clinical trials have evaluated their efficacy in children undergoing surgical correction of scoliosis, but no systematic review has been published. This review was first published in 2008 and was updated in 2016. OBJECTIVES To assess the efficacy and safety of aprotinin, tranexamic acid and aminocaproic acid in reducing blood loss and transfusion requirements in children undergoing surgery for correction of idiopathic or secondary scoliosis. SEARCH METHODS We ran the search for the previous review in June 2007. For this updated version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 7), MEDLINE (1946 to August week 1 2015), Embase (1947 to 2015 week 38), Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 14 August 2015), Database of Abstracts of Reviews of Effects (DARE; 2015, Issue 2) and reference lists of reviews and retrieved articles for randomized controlled trials in any language. We also checked the clinical trial registry at http://www.clinicaltrials.gov on 8 October 2015. SELECTION CRITERIA We included blinded and unblinded randomized controlled trials (RCTs) that evaluated the effects of antifibrinolytics on perioperative blood loss in children 18 years of age or younger and undergoing scoliosis surgery. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data. The primary outcome was total blood loss (intraoperative and postoperative combined). Secondary efficacy outcomes were the number of participants receiving blood transfusion (both autologous and allogeneic) or receiving allogeneic blood transfusion alone, and the total amount of blood transfused. Safety outcomes included the number of deaths, the number of participants reporting any adverse event or a serious adverse event, withdrawals due to adverse events and the number of participants experiencing a specific adverse event (i.e. renal insufficiency, hypersensitivity or thrombosis). We assessed methodological risk of bias for each included study and employed the GRADE approach to assess the overall quality of the evidence. MAIN RESULTS We included three new studies (201 participants) in this updated review, for a total of nine studies (455 participants). All but one study employed placebo as the control group intervention. For the primary outcome, antifibrinolytic drugs decreased the amount of perioperative blood loss by 427 mL (95% confidence interval (CI) 251 to 603 mL), for a reduction of over 20% versus placebo. We rated the quality of evidence for our primary outcome as low on the basis of unclear risk of bias for several domains in most studies and the small total number of participants.For secondary outcomes, fewer participants receiving antifibrinolytic drugs received transfusion (allogeneic or autologous) versus those receiving placebo (risk ratio (RR) 0.65, 95% CI 0.50 to 0.85, number needed to treat to prevent one additional harmful outcome (NNTp) 5; very low-quality evidence). Only two studies specifically evaluated the number of participants transfused with only allogeneic blood (risk difference (RD) -0.15, 95% CI -0.26 to -0.03, NNTp 7; very low-quality evidence). Antifibrinolytic drugs decreased the volume of blood transfused by 327 mL (95% CI -186 to -469 mL; low-quality evidence).No study reported deaths in active or control groups. Data were insufficient to allow performance of meta-analysis for any safety outcome. No studies adequately described their methods in assessing safety. The only adverse event of note occurred in one study, when three participants in the placebo group developed postoperative deep vein thrombosis. AUTHORS' CONCLUSIONS Since the last published version of this review (2008), we have found three new studies. Additional evidence shows that antifibrinolytics reduce the requirement for both autologous and allogeneic blood transfusion. Limited evidence of low to very low quality supports the use of antifibrinolytic drugs for reducing blood loss and decreasing the risk, and volume, of transfusion in children undergoing scoliosis surgery. Evidence is insufficient to support the use of a particular agent, although tranexamic acid may be preferred, given its widespread availability. The optimal dose regimen for any of these three agents has not been established. Although adverse events appear to occur infrequently, evidence is insufficient to confirm the safety of these agents, particularly for rare but potentially catastrophic events. No long-term safety data are available.

Abstract
Background Open heart surgeries under cardiopulmonary bypass are associated with excessive perioperative bleeding that often requires reoperation. Antifibrinolytics like epsilon aminocaproic acid and tranexamic acid are widely used to control bleeding. There are limited studies primarily showing the impact of these drugs on the incidence of reopening following open heart surgical procedures. The goal of this study was to compare incidence of reopening following open heart surgeries in patients who were administered either epsilon amino caproic acid or tranexamic acid for control of perioperative bleeding. Methods A prospective, randomized, controlled trial was performed among seventy-eight patients of either sex in the age group of 18 to 65 years scheduled for open heart surgeries under cardiopulmonary bypass. They were randomly allocated into three groups where group A (n=26) received epsilon aminocaproic acid, group B (n=26) received tranexamic acid and group C (control group, n=26) received intravenous 0.9% normal saline. Patients had similar anaesthetic protocols, and were monitored for twenty-four hours postoperatively to assess reopening rates because of excessive bleeding. Results Two patients in each group receiving either tranexamic acid or epsilon aminocaproic acid had excessive bleeding requiring reopening after surgery whereas three patients in the control group had undergone reopening for excessive bleeding (p>0.05). Conclusions Epsilon aminocaproic acid and tranexamic acid exhibit similar and comparable effect to placebo on incidence of reopening for excessive bleeding following open heart surgeries under cardiopulmonary bypass

Abstract
STUDY DESIGN Prospective clinical study. OBJECTIVE To analyze the amount of blood loss at different stages of Posterior Instrumented Spinal Fusion (PSF) surgery in adolescent idiopathic scoliosis (AIS) patients. SUMMARY OF BACKGROUND DATA Knowing the pattern of blood loss at different surgical stages may enable the surgical team to formulate a management strategy to reduce intraoperative blood loss. METHODS One hundred AIS patients who underwent PSF from January 2013 to December 2014 were recruited. The operation was divided into six stages; stage 1-exposure, stage 2-screw insertion, stage 3-release, stage 4-correction, stage 5-corticotomies and bone grafting, and stage 6-closure. The duration and blood loss at each stage was documented. The following values were calculated: total blood loss, blood loss per estimated blood volume, blood loss per minute, blood loss per vertebral level fused, and blood loss per minute per vertebral level fused. RESULTS There were 89 females and 11 males. The mean age was 17.0 ± 5.8 years old. Majority (50.0%) were Lenke 1 curve type. The mean preoperative major Cobb angle was 64.9 ± 15.0°. The mean number of levels fused was 9.5 ± 2.3 levels. The mean operating time was 188.5 ± 53.4 minutes with a mean total blood loss 951.0 ± 454.0 mLs. The highest mean blood loss occurred at stage 2 (301.0 ± 196.7 mL), followed by stage 4 (226.8 ± 171.2 mL) and stage 5 (161.5 ± 146.6 mL). The highest mean blood loss per minute was at stage 5 (17.1 ± 18.3 mL/min), followed by stage 3 (12.0 ± 10.8 mL/min). The highest mean blood loss per vertebral levels fused was at stage 2 (31.0 ± 17.7 mL/level), followed by stage 4 (23.9 ± 18.1 mL/level) and stage 5 (16.6 ± 13.3 mL/level). CONCLUSION All stages were significant contributors to the total blood loss except exposure (stage 1) and closure (stage 6). Blood loss per minute and blood loss per minute per level was highest during corticotomies (stage 5), followed by release (stage 3). However, the largest amount of total blood loss occurred during screw insertion (stage 2). LEVEL OF EVIDENCE 2.

Abstract
Study Design Combination of narrative and systematic literature reviews. Objectives Massive perioperative blood loss in complex spinal surgery often requires blood transfusions and can negatively affect patient outcome. Systemic use of the antifibrinolytic agent tranexamic acid (TXA) has become widely used in the management of surgical bleeding. We review the clinical evidence for the use of intravenous TXA as a hemostatic agent in spinal surgery and discuss the emerging role for its complementary use as a topical agent to reduce perioperative blood loss from the surgical site. Through a systematic review of published and ongoing investigations on topical TXA for spinal surgery, we wish to make spine practitioners aware of this option and to suggest opportunities for further investigation in the field. Methods A narrative review of systemic TXA in spinal surgery and topical TXA in surgery was conducted. Furthermore, a systematic search (using PRISMA guidelines) of PubMed (MEDLINE), EMBASE, and Cochrane CENTRAL databases as well as World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov (National Institutes of Health), and International Standard Randomized Controlled Trial Number registries was conducted to identify both published literature and ongoing clinical trials on topical TXA in spinal surgery. Results Of 1,631 preliminary search results, 2 published studies were included in the systematic review. Out of 285 ongoing clinical trials matching the search criteria, a total of 4 relevant studies were included and reviewed. Conclusion Intravenous TXA is established as an efficacious hemostatic agent in spinal surgery. Use of topical TXA in surgery suggests similar hemostatic efficacy and potentially improved safety as compared with intravenous TXA. For spinal surgery, the literature on topical TXA is sparse but promising, warranting further clinical investigation and consideration as a clinical option in cases with significant anticipated surgical site blood loss.

Abstract
STUDY DESIGN A prospective, randomized, controlled clinical study. OBJECTIVE To determine the efficacy of bipolar sealer device in reducing perioperative blood loss and transfusions in degenerative lumbar scoliosis patients undergoing primary posterior spinal fusion. BACKGROUND It has recently been used successfully in pediatric spine surgery, particularly in idiopathic and neuromuscular deformities. However, there is a dearth of literature on prospective study of the efficacy of bipolar sealer device in reducing perioperative blood loss and transfusions in patients undergoing degenerative lumbar scoliosis surgery. METHODS A total of 100 consecutive degenerative lumbar scoliosis patients who had undergone primary decompression and posterior spinal fusion with segmental spinal instrumentation between June 2010 and June 2012 were prospectively randomized into 1 of 2 groups according to whether bipolar sealer device for intraoperative/postoperative blood management was used or not. Demographic distribution, perioperative blood loss, blood transfusion rate, the length of stay, and postoperative complications were analyzed. RESULTS The operation time was significantly shorter in the study group than in the control group, 223.4 versus 248.9 minutes (P=0.026). There was significantly lower intraoperative estimated blood loss in the bipolar sealer group, 407 versus 696 mL (P=0.000). Of the patients with the use of bipolar sealer device, the mean red blood cell transfusion requirement during hospitalization was significantly less than the control group, 0.4 versus 1.1 U/patient (P=0.003). Furthermore, significant difference existed in allogenic blood transfusion rate between the 2 cohorts. Within the study group (with the use of bipolar sealer device), the entire perioperative allogenic blood transfusion rate was 18.0% compared with 40.0% of the control group (P=0.015). There were no complications related directly to the use of the bipolar sealer. CONCLUSIONS Utilization of a bipolar sealer during correction of lumbar degenerative scoliosis may offer comparable hemostatic effects, without prohibitive cost or adverse drug-related risks.

Abstract
Background Many reports had been received on the application of antifibrinolytic medications on spinal corrective surgery and the surgical outcome evaluations of its efficacy on reducing blood loss. This study aimed to assess the efficacy of tranexamic acid (TXA) in reducing operative blood loss during posterior spinal fusion for the treatment of severe adolescent idiopathic scoliosis (AIS). Methods A retrospective cohort study was carried out on 90 (TXA = 55, Control = 35) AIS girls undergoing posterior spinal surgery. Patients in TXA group used TXA as an antifibrinolytic agent to reduce blood loss, while control group did not. Blood loss, haemoglobin change and amount of blood transfused was estimated from intraoperative measurement by anaesthesiologists. Demographics were compared using Student’s T-test or Chi-square test where appropriate. Linear regression modelling was carried out between the use of TXA and total blood loss with controlling of confounding factors. Results Mean age and mean maximum major curve were 15.2 and 73°, and 15.3 and 63° in TXA and control groups respectively. TXA group showed significantly less intra-operative blood loss than the control group from intraoperative measurement (1.8 L vs. 3.9 L, p < 0.01) and volume of cell saver blood transfused back to patients (0.6 L vs. 1.7 L, p < 0.01). TXA group also showed significantly shorter total time taken for surgery (437 min vs. 502 min, p < 0.01), and total blood loss per surgical segment level (0.1 L vs. 0.3 L, p < 0.01). Regression models showed that the use of TXA decreased total blood loss by 794.3 ml after adjusting for maximum major curve, age, number of segments fused, bone graft, clotting capability, and infusion of coagulation factors. Conclusions Patients undergoing posterior spinal corrective surgery with the use of TXA showed much reduced total blood loss, reduced use of transfused blood, much less cell saver blood transfused back to the patient. The total blood loss was decreased by after using TXA after controlling for maximum major curve, age, surgical parameters, clotting capability, and infusion of coagulation factors.

Abstract
OBJECTIVE Our objective was to evaluate the efficacy and safety of Batroxobin on blood loss during spinal operations. METHODS After obtaining approval from the ethics committee at the hospital along with informed written consent, we performed a double-blind, randomized, placebo-controlled study with 100 patients who were randomized equally into 2 groups (Batroxobin and placebo). Patients received either 2 ku IV 15 min before surgery and followed 1 ku IM of Batroxobin following surgery, or an equivalent volume of placebo (normal saline). Cost of Batroxobin treatment is amounted to 84.75 euros. The primary outcomes were intraoperative, 24 h postoperative, and total perioperative blood loss. Secondary outcomes were hemoglobin (Hb), red blood cell count (RBC), the volume of blood/fluid transfusion intraoperatively, and 24 h postoperatively. Safety evaluation parameters were the incidence of venous thrombosis in the lower extremities, active partial thromboplastin time, prothrombin time, thrombin time, and fibrinogen. The data were analyzed using the Statistical Package for the Social Science Version 12.0. The results were presented as mean ± SEM. The Mann-Whitney test and Independent Student t test, when appropriate, were used to compare the 2 groups, and differences were considered significant if the P value was <0.05. RESULTS 88 patients were included in the analysis while 12 patients were withdrawn from the study due to extended surgical duration, change of surgical procedure, or after the patients' request. The total perioperative blood loss was approximately 31% lower in patients given Batroxobin versus placebo (700.5 ± 45.81 vs 485.7 ± 30.01 mL, P = 0.001). The Batroxobin group had significantly less intraoperative blood loss (326.1 ± 24.16) compared to the placebo group (556.0 ± 43.58), but there was no difference in the amount of blood/fluid transfused, postoperatively Hb, or RBC between the two groups. After the operation, coagulation parameters were not significantly different between the 2 groups at the days 1 or 3 postoperatively. No adverse events related to the use of Batroxobin were recorded. There were no cases of superficial wound infection. None of the subjects died during the study. CONCLUSIONS In this study, prophylactic use of Batroxobin provided an effective and cheap method for reducing blood loss without coagulopathy during or after operations. The use of Batroxobin for patients undergoing one-level PLIF surgery safely and effectively reduced the total amount of perioperative blood loss.

Abstract
BACKGROUND Rett syndrome is a rare genetically inherited neuromuscular disorder exclusively affecting female patients. Progressive scoliosis is one of the main features of the disease and affected individuals are very likely to need spine correction surgery. METHODS We undertook a retrospective notes review of patients with Rett syndrome who had undergone spine surgery from 2005 to 2013. Patients were identified through the hospital's electronic records. The aim of the present study was to identify the anesthetic implications encountered and the perioperative adverse events, in an effort to improve perioperative management and reduce complications. RESULT We identified twenty-four children who had 29 procedures in total in this period. Frequent chest infections and poorly controlled epilepsy were the main preoperative findings. There were no adverse events during induction and intubation. Common anesthetic/analgesic drugs were used throughout. Postoperatively, gastrointestinal and respiratory tract complications were the most common. Mean intensive care unit stay was 8.1 days and mean time to discharge from hospital was 26.5 days. We had one in-hospital death. CONCLUSIONS Our case series demonstrates a high incidence of complications in this subpopulation, mainly postoperative. Extreme postoperative vigilance is required and recovery in a high dependency unit is highly recommended.

Abstract
STUDY DESIGN Retrospective uncontrolled case series. OBJECTIVE The purpose of this study was to determine the association, if any, between intraoperative blood loss and need for transfusion with the use of periapical (Ponte) osteotomies, as well as other patient and surgical variables among patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal instrumentation and fusion. SUMMARY OF BACKGROUND DATA Blood loss during posterior spinal fusion for AIS can be substantial. Numerous techniques are used to minimize intraoperative blood loss and the need for allogeneic transfusion. However, it is unclear which patient and surgeon variables affect blood loss most significantly. METHODS A review was conducted on consecutive patients with AIS who had undergone posterior spinal fusion from July 1997 to February 2013 by a single primary surgeon at 1 institution. The relationship of estimated blood loss, normalized blood loss (normalized blood loss = estimated blood loss/number of levels fused/patient's weight in kilograms), autologous blood retrieved, and allogeneic transfusion received with various patient- and procedure-related variables were analyzed. RESULTS Estimated blood loss, normalized blood loss, and autologous blood retrieved were higher in patients who underwent periapical Ponte osteotomies (n = 38) (P < 0.0001, P < 0.001, P < 0.01, respectively). The mean major curve correction was 64% in patients without osteotomies, and 65% in patients with osteotomies (P = 0.81). All patients who underwent osteotomies (38/38) received allogeneic transfusion versus 26% (19/73) of those without osteotomies (P < 0.001). The likelihood of transfusion correlated with increasing number of osteotomies and a lower preoperative hemoglobin level (odds ratio, 3.34; P = 0.003; and odds ratio, 0.51; P = 0.02, respectively). CONCLUSION In patients with AIS undergoing posterior spinal fusion with instrumentation, performing periapical osteotomies increased all measures of intraoperative blood loss and need for transfusion without substantially improving major curve correction. As expected, a lower preoperative hemoglobin level was observed in patients who received a blood transfusion after posterior instrumentation and fusion. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND Antifibrinolytics can reduce intraoperative blood loss. The primary aim of this study was to determine the efficacy of intraoperative tranexamic acid, epsilon-aminocaproic acid, and placebo at reducing perioperative blood loss and the transfusion rate in patients with adolescent idiopathic scoliosis undergoing posterior spinal arthrodesis. METHODS This is a prospective, randomized, double-blind comparison of tranexamic acid, epsilon-aminocaproic acid, and placebo used intraoperatively in patients with adolescent idiopathic scoliosis. One hundred and twenty-five patients with adolescent idiopathic scoliosis were randomly assigned to the tranexamic acid, epsilon-aminocaproic acid, or control groups. Parameters recorded included estimated blood loss, hematocrit, blood product usage, drain output, and total blood losses. The primary outcomes were intraoperative blood loss and postoperative drainage. Secondary outcomes were transfusion requirements and hematocrit changes both intraoperatively and postoperatively. RESULTS One hundred and twenty-five patients (ninety-seven female and twenty-eight male, with a mean age of fifteen years) were randomized to receive tranexamic acid (thirty-six patients), epsilon-aminocaproic acid (forty-two patients), or saline solution (forty-seven patients). The groups were similar at baseline, with one exception: the saline solution group had a higher estimated blood volume at baseline than the tranexamic acid group. Both tranexamic acid and epsilon-aminocaproic acid reduced the estimated blood loss per degree and estimated blood loss per pedicle screw. Epsilon-aminocaproic acid, but not tranexamic acid, reduced estimated blood loss and estimated blood loss per level. Tranexamic acid also reduced total blood losses compared with epsilon-aminocaproic acid or saline solution. In an analysis controlling for level, degree, and number of anchors, tranexamic acid reduced drain output and total blood losses. Tranexamic acid or epsilon-aminocaproic acid had a smaller decrease in hematocrit postoperatively. In an analysis controlling for the mean arterial pressure during surgical exposure, tranexamic acid reduced estimated blood loss and total blood losses. Overall, antifibrinolytics (tranexamic acid or epsilon-aminocaproic acid) reduced estimated blood loss, total blood losses, and the decline in hematocrit postoperatively compared with saline solution. There was no difference among the groups with respect to the transfusion rate, duration of surgery, levels fused, or pedicle screws placed. CONCLUSIONS Tranexamic acid and epsilon-aminocaproic acid reduced operative blood loss but not transfusion rate. Tranexamic acid is more effective at reducing postoperative drainage and total blood losses compared with epsilon-aminocaproic acid. Maintenance of the mean arterial pressure at <75 mm Hg during surgical exposure appears to be critical for maximizing antifibrinolytic benefit. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
There are 3 surgical procedures that patients with cerebral palsy (CP) undergo that may be considered major procedures: femoral osteotomies combined with pelvic osteotomies, spine fusion, and intrathecal baclofen pump implant for the treatment of spasticity. Many complications are known to occur at a higher rate in this population, and some may be avoided with prior awareness of the preoperative pathophysiology of the patient with CP.

Abstract
STUDY DESIGN Retrospective case report of 2 cases. OBJECTIVE To describe 2 cases of cervical spinal cord injury/vascular insult after posterior instrumentation of thoracic/thoracolumbar scoliosis. SUMMARY OF BACKGROUND DATA Spinal cord injury is an uncommon but well-documented complication associated with spinal deformity surgery. The midthoracic spinal cord is most vulnerable to these presumed vascular insults. Injuries above the level of instrumentation are rare. METHODS In this report, we review the clinical histories of 2 adolescent females undergoing posterior spinal fusion with subsequent cervical spinal cord injuries. RESULTS In both cases, intraoperative cervical alignment appeared neutral and all hardware appeared appropriately positioned. Spinal cord monitoring demonstrated changes in 1 patient but not in the other. With time, both patients improved clinically. CONCLUSION Cervical spinal cord injuries may occur after distal deformity correction.

Abstract
PURPOSE Spine surgery, particularly reconstructive surgery, can be associated with significant blood loss, and blood transfusion. Antifibrinolytic agents are used routinely to reduce bleeding in cardiac, orthopaedic, and hepatic surgery. The purpose of this study was to assess the efficacy and safety of using antifibrinolytic agents in reducing blood loss and blood transfusions in spine surgery. METHODS A systematic search of all related studies written in English published by October 2012 was conducted using the MEDLINE, EMBASE and the Cochrane Library databases. Randomized controlled trials that reported the drug dosage, total blood loss, blood transfusion and incidence of deep vein thrombosis as the primary outcome were included. RESULTS Nine studies involving 482 patients were identified. Patients receiving antifibrinolytic agents had reduced blood loss (WMD =-288.8, 95 % CI - 46.49, - 110.19; P = 0.002), reduced blood transfusion (WMD =-242.7, 95 % CI - 422.57, - 62.95; P = 0.008), reduced blood transfusion rate (RR 0.73, 95% CI 0.58, 0.93; p = 0.010) and no increase (RR 0.25, 95 % CI 0.03, 2.22; P = 0.21) in the risk of deep vein thrombosis. CONCLUSIONS We conclude that antifibrinolytic agents significantly decrease blood loss, blood transfusion, and there is no increase in the risk of deep vein thrombosisfor transfusion requirements in spine surgery.

Abstract
Antifibrinolytic drugs have become almost ubiquitous in their use during major surgery when bleeding is expected or commonplace. Inhibition of the fibrinolytic pathway after tissue injury has been consistently shown to reduce postoperative or traumatic bleeding. There is also some evidence for a reduction of perioperative blood transfusion. However, evidence of complications associated with exaggerated thrombosis also exists, although this appears to be influenced by the choice of the individual agent and the dose administered. There is controversy over the use of the serine protease inhibitor aprotinin, whose license was recently withdrawn but may shortly become available on the market again. In the UK, tranexamic acid, a tissue plasminogen and plasmin inhibitor, is most commonly used, with evidence for benefit in cardiac, orthopaedic, urological, gynaecological, and obstetric surgery. In the USA, ε-aminocaproic acid, which also inhibits plasmin, is commonly used. We have reviewed the current literature for this increasingly popular class of drugs to support clinical judgement in daily anaesthetic practice.

Which is more effective in adolescent idiopathic scoliosis surgery: batroxobin, tranexamic acid or a combination? Arch Orthop Trauma Surg 2012; 132:25-31.

Abstract
BACKGROUND Adolescent idiopathic scoliosis surgery is often associated with significant blood loss and blood transfusion. In this clinical trial, the authors investigated the efficacy of reducing blood loss and allogeneic blood transfusion by using batroxobin, tranexamic acid (TXA) and the combination of the two agents. METHODS 80 adolescent patients undergoing scheduled idiopathic scoliosis surgery were randomly divided into four groups to receive 0.9% saline (group A), batroxobin (group B), TXA (group C), and both two agents in the same manner (group D). The amounts of blood loss, transfusion requirements, frozen fresh plasma (FFP) and overall drainage were assessed. The hemoglobin concentration (Hb), hematocrit and platelet counts were recorded preoperative y, postoperatively and on the first operative day. The coagulation parameters were measured meanwhile. Deep vein thrombosis (DVT) was diagnosed by ultrasound. RESULTS Blood loss of group B and group C decreased similarly by 35.3 and 42.8% (p = 0.212) compared with group A, while group D was reduced by 64.5, 45.1 and 37.8% compared to group A, B and C, respectively. The amount of allogeneic blood transfusion of group B and group C was comparably reduced by 57.6 and 72.4% compared to group A (p = 0.069), while group D decreased by 94.7, 87.5 and 80.9% compared to group A, B and C. Overall drainage of group B, C and D decreased by 23.0, 45.1 and 67.9% compared with group A, respectively, while group C was reduced by 28.7% compared with group B (p < 0.001). The FFP of group B, C and D was reduced by 63.4, 80.2 and 95.0% as compared with group A, while group C decreased by 45.9% as compared to group B (p = 0.025). There were no urgent coagulation disorders or DVT reported. CONCLUSIONS In our study, batroxobin and TXA can markedly reduce the blood loss and the transfusion requirements equivalently. However, TXA performs better in minimizing FFP and the overall drainage than batroxobin. The combination seems to achieve best results and was more effective than either of the two drugs alone. No apparent adverse events were detected in these groups.

Abstract
BACKGROUND Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. METHODS This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments). Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. RESULTS The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39). The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units) was needed for eight patients in the tranexamic acid group and nine in the control group because of postoperative anemia. Complications associated with the administration of tranexamic acid, e.g. renal failure, deep vein thrombosis or pulmonary embolism did not occur. CONCLUSIONS This study suggests a less blood loss when administering tranexamic acid in posterior lumbar spine surgery as demonstrated by the higher postoperative hemoglobin concentration and the less blood loss. But given the relatively small volume of blood loss in the patients of this study it is underpowered to show a difference in transfusion rates.

Abstract
BACKGROUND Concerns regarding the safety of transfused blood have led to the development of a range of interventions to minimise blood loss during major surgery. Anti-fibrinolytic drugs are widely used, particularly in cardiac surgery, and previous reviews have found them to be effective in reducing blood loss, the need for transfusion, and the need for re-operation due to continued or recurrent bleeding. In the last few years questions have been raised regarding the comparative performance of the drugs. The safety of the most popular agent, aprotinin, has been challenged, and it was withdrawn from world markets in May 2008 because of concerns that it increased the risk of cardiovascular complications and death. OBJECTIVES To assess the comparative effects of the anti-fibrinolytic drugs aprotinin, tranexamic acid (TXA), and epsilon aminocaproic acid (EACA) on blood loss during surgery, the need for red blood cell (RBC) transfusion, and adverse events, particularly vascular occlusion, renal dysfunction, and death. SEARCH STRATEGY We searched: the Cochrane Injuries Group's Specialised Register (July 2010), Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 3), MEDLINE (Ovid SP) 1950 to July 2010, EMBASE (Ovid SP) 1980 to July 2010. References in identified trials and review articles were checked and trial authors were contacted to identify any additional studies. The searches were last updated in July 2010. SELECTION CRITERIA Randomised controlled trials (RCTs) of anti-fibrinolytic drugs in adults scheduled for non-urgent surgery. Eligible trials compared anti-fibrinolytic drugs with placebo (or no treatment), or with each other. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. This version of the review includes a sensitivity analysis excluding trials authored by Prof. Joachim Boldt. MAIN RESULTS This review summarises data from 252 RCTs that recruited over 25,000 participants. Data from the head-to-head trials suggest an advantage of aprotinin over the lysine analogues TXA and EACA in terms of reducing perioperative blood loss, but the differences were small. Compared to control, aprotinin reduced the probability of requiring RBC transfusion by a relative 34% (relative risk [RR] 0.66, 95% confidence interval [CI] 0.60 to 0.72). The RR for RBC transfusion with TXA was 0.61 (95% CI 0.53 to 0.70) and was 0.81 (95% CI 0.67 to 0.99) with EACA. When the pooled estimates from the head-to-head trials of the two lysine analogues were combined and compared to aprotinin alone, aprotinin appeared more effective in reducing the need for RBC transfusion (RR 0.90; 95% CI 0.81 to 0.99).Aprotinin reduced the need for re-operation due to bleeding by a relative 54% (RR 0.46, 95% CI 0.34 to 0.62). This translates into an absolute risk reduction of 2% and a number needed-to-treat (NNT) of 50 (95% CI 33 to 100). A similar trend was seen with EACA (RR 0.32, 95% CI 0.11 to 0.99) but not TXA (RR 0.80, 95% CI 0.55 to 1.17). The blood transfusion data were heterogeneous and funnel plots indicate that trials of aprotinin and the lysine analogues may be subject to publication bias.When compared with no treatment aprotinin did not increase the risk of myocardial infarction (RR 0.87, 95% CI 0.69 to 1.11), stroke (RR 0.82, 95% CI 0.44 to 1.52), renal dysfunction (RR 1.10, 95% CI 0.79 to 1.54) or overall mortality (RR 0.81, 95% CI 0.63 to 1.06). Similar trends were seen with the lysine analogues, but data were sparse. These data conflict with the results of recently published non-randomised studies, which found increased risk of cardiovascular complications and death with aprotinin. There are concerns about the adequacy of reporting of uncommon events in the small clinical trials included in this review.When aprotinin was compared directly with either, or both, of the two lysine analogues it resulted in a significant increase in the risk of death (RR 1.39, 95% CI 1.02, 1.89), and a non-significant increase in the risk of myocardial infarction (RR 1.11 95% CI 0.82, 1.50). Most of the data contributing to this added risk came from a single study - the BART trial (2008). AUTHORS' CONCLUSIONS Anti-fibrinolytic drugs provide worthwhile reductions in blood loss and the receipt of allogeneic red cell transfusion. Aprotinin appears to be slightly more effective than the lysine analogues in reducing blood loss and the receipt of blood transfusion. However, head to head comparisons show a lower risk of death with lysine analogues when compared with aprotinin. The lysine analogues are effective in reducing blood loss during and after surgery, and appear to be free of serious adverse effects.

Abstract
OBJECTIVE The aim of this study is critically to review the available evidence regarding the use, efficacy and safety of tranexamic acid in the management of hemorrhage during pregnancy and for prevention and treatment of postpartum hemorrhage. RESEARCH DESIGN AND METHODS We performed a systematic search of electronic literature (PubMed, Embase, CINAHL, Scopus, Cochrane, DARE) to review all studies looking at the use of tranexamic acid during pregnancy and puerperium. We did a meta-analysis on three randomized controlled trials that evaluated reduction in blood loss in women undergoing cesarean sections with the use of tranexamic acid. RESULTS An electronic search yielded 34 articles, the studies dating from 1976 to 2010, five randomized controlled trials, seven observational studies, and twenty-two case reports. Meta-analysis showed that the estimate of the combined effect of tranexamic acid compared with placebo was a difference of 32.5 ml reduction in blood loss (95% CI -4.1-69.13; p = 0.08). Tranexamic acid was also used successfully to prevent and treat bleeding in observation studies and case reports. Pulmonary embolism was reported in two cases; however, the possible involvement of tranexamic acid in these thrombotic episodes could neither be confirmed nor excluded. CONCLUSIONS The clinical studies suggest that tranexamic acid reduces the amount of blood loss after delivery during cesarean sections and vaginal deliveries, and reduces the requirement for blood transfusion. Tranexamic acid seems to be safe and effective in the prevention and management of bleeding during pregnancy. Further investigation and larger clinical trials with better design and methodological quality are required to confirm these findings.

The blood transfusion data were heterogeneous and funnel plots indicate that trials of aprotinin and the lysine analogues may be subject to publication bias.When compared with no treatment aprotinin did not increase the risk of myocardial infarction (RR 0.87, 95% CI 0.69 to 1.11), stroke (RR 0.82, 95% CI 0.44 to 1.52), renal dysfunction (RR 1.10, 95% CI 0.79 to 1.54) or overall mortality (RR 0.81, 95% CI 0.63 to 1.06). Similar trends were seen with the lysine analogues, but data were sparse. These data conflict with the results of recently published non-randomised studies, which found increased risk of cardiovascular complications and death with aprotinin. There are concerns about the adequacy of reporting of uncommon events in the small clinical trials included in this review.When aprotinin was compared directly with either, or both, of the two lysine analogues it resulted in a significant increase in the risk of death (RR 1.39, 95% CI 1.02, 1.89), and a non-significant increase in the risk of myocardial infarction (RR 1.11 95% CI 0.82, 1.50). Most of the data contributing to this added risk came from a single study - the BART trial (2008). AUTHORS' CONCLUSIONS Anti-fibrinolytic drugs provide worthwhile reductions in blood loss and the receipt of allogeneic red cell transfusion. Aprotinin appears to be slightly more effective than the lysine analogues in reducing blood loss and the receipt of blood transfusion. However, head to head comparisons show a lower risk of death with lysine analogues when compared with aprotinin. The lysine analogues are effective in reducing blood loss during and after surgery, and appear to be free of serious adverse effects.

Abstract
Patients undergoing total hip or knee arthroplasty often sustain significant decreases in hemoglobin and hematocrit, despite modern techniques and shorter operating times. Reasons for the blood loss include raw bony surfaces, vascular inflammatory tissue, and fragile vessels in elderly patients. Acute postoperative anemia has numerous deleterious effects on patients, including delayed rehabilitation, exposure to allogeneic blood transfusions, higher complication rates, and increased pain. The ability to limit the amount of postoperative bleeding may reduce the amount of postoperative pain that patients experience, ultimately resulting in greater patient satisfaction and smoother postoperative rehabilitation. This article focuses on intraoperative techniques available to limit bleeding, thereby minimizing pain and the need for postoperative transfusion.
