Abstract
Surgical correction of craniosynostosis can involve significant blood loss. Rates of allogenic blood transfusion have been reported to approach 100%. Multiple interventions have been described to reduce blood loss and transfusion requirements. The aim of this study was to analyze various approaches over the last 4 decades to optimize blood loss and management during craniosynostosis surgery. PRISMA guidelines for systematic reviews were followed. PubMed and Cochrane database searches identified studies analyzing approaches to minimizing blood loss or transfusion rate in craniosynostosis surgery. Primary outcomes included rate or amount of allogenic or autologous blood transfusion, estimated blood loss (EBL), postoperative hemoglobin (Hg), or hematocrit (Hct) levels. Secondary outcomes were examined when reported. Fifty-two studies met inclusion criteria. There was marked heterogeneity regarding design, inclusion criteria, surgical intervention, and endpoints. The majority of the studies were nonrandomized and noncomparative. Four studies analyzed erythropoietin (EPO), 6 analyzed various cell-saver (CS) technologies, 18 analyzed antifibrinolytics (tranexamic acid [TXA], aminocaproic acid [ACA], and aprotinin [APO]), 8 analyzed various alternatives, and 16 analyzed multimodal pathways & protocols. Some studies analyzed multiple approaches. Although the majority of studies reviewed represent level III/IV evidence, several high-quality level I studies were identified and included. Level I evidence supported an improvement in blood outcomes by utilizing EPO, CS, and TXA, individually or in concert with one another. Thus, this review suggests that a multi-prong approach may be the most effective means to optimize blood loss and transfusion outcomes in craniosynostosis surgery.

Abstract
Although many published studies have investigated the benefits of tranexamic acid (TXA) in reducing perioperative bleeding, no large meta-analysis has been conducted to demonstrate its overall benefit. Methods A systematic review was performed by following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. PubMed, Cochrane, Ovid, Embase, Web of Science, ClinicalTraisl.Gov, and Scopus databases were searched for articles reporting the benefit of TXA in reducing perioperative bleeding in craniosynostosis surgery from establishment through October 2022. The results of our meta-analysis were pooled across the studies using a random-effects model, and presented as a weighted mean difference with 95% confidence interval (95% CI). Results The database search yielded 3207 articles, of which 27 studies with a corresponding number of 9696 operations were eligible. The meta-analysis included only 18 studies, accounting for 1564 operations. Of those operations, 882 patients received systemic TXA, whereas 682 patients received placebo (normal saline), no intervention, low dose TXA, or other control substances. This meta-analysis demonstrated a significant beneficial effect of TXA in reducing perioperative bleeding, particularly when compared with other controlled substances, with a weighted mean difference of -3.97 (95% CI = -5.29 to -2.28). Conclusions To our knowledge, this is the largest meta-analysis in the literature investigating the benefit of TXA in reducing perioperative blood loss in craniosynostosis surgery. We encourage implementing TXA-protocol systems in hospitals after the appraisal of the data presented in this study.

[PMID: 37489171 PMCID: PMC10363360 DOI: 10.5812/aapm-130462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 12/12/2022] [Accepted: 12/26/2022] [Indexed: 07/26/2023] Open
Abstract
Background Open cranial vault reconstruction is the standard technique of craniosynostosis correction that may cause significant blood loss. Objectives The current study aimed at comparing the effect of tranexamic acid (TXA), controlled hypotension, and their combination on perioperative blood loss and transfusion requirement in craniosynostosis surgery. Methods The present randomized, double-blind clinical trial was conducted on 75 infants referred for craniosynostosis surgery during 2017 - 2018. Ten minutes before the start of surgery, 10 mg/kg of TXA was administered intravenously to patients in the first group (TXA group). In the second group, patients were subjected to the controlled hypotension anesthesia (CHA) using intravenous remifentanil 0.1 μ/kg (CHA group). In the third group, the patients underwent CHA similar to that of the second group, along with intravenous injection of 10 mg/kg of TXA (CHA-TXA group). Then, patients' mean arterial pressure (MAP), heart rate (HR), total blood loss, and transfusion volume were evaluated and recorded. Results The results of the present study revealed that although the changes in MAP and HR parameters over time (three hours after surgery) were significant in all three groups, the lowest decrease was observed in the CHA-TXA group (P-value < 0.05). In addition, the total perioperative blood loss in the CHA-TXA group with the mean of 181.20 ± 82.71 cc was significantly less than the total perioperative blood loss in the CHA and TXA groups with the means of 262.00 ± 104.04 cc and 212.80 ± 80.75 cc, respectively (P-value < 0.05). Moreover, the transfusion volume in the CHA-TXA group with the mean of 112.40 ± 53.50 cc was significantly lower than the transfusion volume in the CHA and TXA groups with the means of 174.00 ± 73.93 cc and 160.63 ± 59.35 cc, respectively (P-value < 0.05). In contrast, the total blood loss and transfusion volume were not significantly different between the CHA and TXA groups (P-value > 0.05). Conclusions According to the results of the present study, although the administration of TXA alone could effectively prevent blood loss and was associated with fewer transfusion requirements, the combination of this approach with hypotensive anesthesia resulted in more reduction in perioperative blood loss and transfusion volume as well as better hemodynamic stability.

Effect of administration of tranexamic acid on blood loss and transfusion requirements in children undergoing posterior fossa tumor excision: a retrospective cohort study. Childs Nerv Syst 2022; 39:877-886. [PMID: 36576551 DOI: 10.1007/s00381-022-05758-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 11/11/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Surgical resection of posterior fossa tumors (PFT) in the pediatric age group often results in significant intraoperative blood loss. The primary objective was to assess the effect of tranexamic acid (TXA) on blood loss and transfusion requirement in pediatric patients undergoing excision of PFT. METHODS In this retrospective study, all pediatric patients ≤ 18 years, who underwent PFT resection over a period of 7 years, were included. The patient and surgical characteristics, estimated blood loss (EBL), the need for blood and blood product transfusion, use of crystalloids, vasopressors, and any adverse events like seizures and thromboembolic events were recorded and compared between Group A who received TXA and Group B who did not. RESULTS The study included 50 patients, out of which 36 belonged to Group A and 14 to Group B. The median age was 8 years (IQR, 2-17) and the mean BMI was 16.46 ± 4.11 kg/m2. The mean EBL was 224.29 ± 110.36 ml in group A (n = 36) and 362 ± 180.11 ml in group B (n = 14) (p = 0.007). The intraoperative volume of crystalloid use was significantly higher in group B (p = 0.04). The requirement of blood and blood product transfusion was similar between the groups, but the volume of blood transfusion per kg body weight was higher in group B, 8.3 (IQR, 6.7-11.1) ml/kg in Group A versus 10.5 (IQR, 8.1-16.1) ml/kg in Group B (p-value 0.3). The rates of complications noted in the form of seizures and thromboembolic events were comparable. CONCLUSION The use of TXA in the pediatric population undergoing PFT resection aids in reducing blood loss during the surgery without increasing complications.

Abstract
This study aimed to compare operative time, blood loss, and transfusion requirement in patients receiving a high tranexamic acid (TXA) dose of greater than 10 mg/kg versus those receiving a low dose of 10 mg/kg or less. Methods PubMed, Cochrane Central, and Embase were queried to perform a systematic review with meta-analysis. Studies reporting outcomes of TXA use in craniosynostosis surgery were included. TXA dosing, operative time, blood loss, and transfusion requirement were the primary outcomes studied. Other variables studied included age and types of craniosynostosis. Results In total, 398 individuals in the included articles received TXA for craniosynostosis surgery. TXA loading doses ranged from 10 mg/kg to 50 mg/kg. Overall, administration of TXA was not associated with changes in operative time, but was associated with decreased blood loss and transfusion requirement on meta-analysis. Comparison of high dose TXA (>10 mg/kg) versus low dose (10 mg/kg or less) showed no statistical differences in changes in operative time, blood loss, or transfusion requirement. Conclusions Overall, TXA reduced blood loss and transfusion requirement in patients undergoing surgery for craniosynostosis. There was no difference in outcomes between high dose and low dose regimens amongst those receiving TXA. Low dose TXA appears adequate to achieve clinical efficacy with a low adverse event rate.

Abstract
OBJECTIVE Tranexamic acid (TXA) is an antifibrinolytic drug that has achieved significant reduction in perioperative blood loss and the quantity of blood transfused in many pediatric surgical procedures, without morbidity. Despite the accumulation of evidence regarding its effectiveness in craniosynostosis repair surgery, TXA is not unanimously employed by pediatric neurosurgery teams. The purpose of this study was to evaluate the impact of the routine use of TXA in a homogeneous population of children who underwent open surgery for monosutural craniosynostosis. METHODS The authors retrospectively reviewed 3 cohorts of patients that were subdivided from 2 cohorts surrounding the initiation of TXA (group 1, TXA- [2008-2011] and group 2, TXA+ [2011-2013]) and a third cohort of more recent patients (group 3, TXA+ [2016-2017]). TXA was administered using the same protocol comprising a loading dose of 10 mg/kg over 15 minutes after induction of general anesthesia followed by a 10 mg/kg per hour infusion until skin closure. Patients in all 3 groups underwent similar standardized procedures for scaphocephaly, trigonocephaly, and unicoronal craniosynostosis by the same pediatric neurosurgeon. RESULTS Overall, 102 infants were included in the study: 32 infants in group 1, 36 in group 2, and 34 in group 3. Significant reductions in transfusion of packed erythrocytes (PE) and fresh-frozen plasma (FFP) were observed between the TXA- and TXA+ time periods. The median volume of PE transfusion was reduced by > 50% with the use of TXA (42.8 mL/kg in the TXA- group vs 20.0 in the TXA+ groups, p < 0.0001). Reduction in PE transfusion was 100% postoperatively in the TXA+ groups (20.0 mL/kg in the TXA- group vs 0.0 in the TXA+ groups, p < 0.0001). The median volume of FFP transfusion was reduced by 100% with the use of TXA (12.8 mL/kg in the TXA- group vs 0.0 in the TXA+ groups, p < 0.0001). All children in group 1 received a transfusion, whereas 3 children (8%) and 7 children (20%) in groups 2 and 3, respectively, did not. Significant reductions in postoperative drain output were also noted between the TXA- and TXA+ time periods. The total hospital length of stay was significantly lower in the TXA+ groups (p < 0.0001). CONCLUSIONS Use of TXA reduced blood loss and the need for transfusions but also decreased the hospital length of stay and, thus, minimized overall medical care costs. Intraoperative administration of TXA in craniosynostosis repair surgery should be routinely used in all centers that practice these procedures.

Safety and efficacy of aprotinin versus tranexamic acid for reducing absolute blood loss and transfusion in pediatric patients undergoing craniosynostosis surgery: a randomized, double-blind, three-arm controlled trial. J Neurosurg Pediatr 2022; 29:551-559.

Abstract
OBJECTIVE Craniosynostosis surgery is associated with considerable blood loss and need for transfusion. Considering the lower estimated blood volume (EBV) of children compared to adults, excessive blood loss may quickly lead to hypovolemic shock. Therefore, reducing blood loss is important in craniosynostosis surgery. This study was conducted to evaluate the efficacy of aprotinin or tranexamic acid (TXA) in blood loss reduction in these patients. METHODS In the current randomized controlled trial, 90 eligible pediatric patients with craniosynostosis were randomly divided into three groups to receive either aprotinin, TXA, or no intervention. The absolute blood loss and transfusion amount were assessed for all patients both intraoperatively and 2 and 8 hours postoperatively. RESULTS Although crude values of estimated blood loss were not significantly different between groups (p = 0.162), when adjusted to the patient's weight or EBV, the values reached the significance level (p = 0.018), particularly when the aprotinin group was compared to the control group (p = 0.0154). The EBV losses 2 hours and 8 hours postoperatively significantly dropped in the TXA and aprotinin groups compared to the control group (p = 0.001 and p < 0.001, respectively). Rates of postoperative blood transfusion were significantly higher in the control group (p = 0.024). Hemoglobin and hematocrit 8 hours postoperatively were lower in the control group than in the TXA or aprotinin treatment groups (p < 0.002 and p < 0.001, respectively). There were no serious adverse events associated with the interventions in this study. CONCLUSIONS Aprotinin and TXA can reduce blood loss and blood transfusion without serious complications and adverse events in pediatric patients undergoing craniosynostosis surgery.

Abstract
OBJECTIVE This study aimed to determine the efficacy and harms of using tranexamic acid (TXA) versus placebo/no intervention to reduce blood loss and the need for transfusion in children undergoing surgical correction of craniosynostosis. METHODS We searched MEDLINE (OVID), EMBASE, LILACS, CENTRAL, and other sources. We included clinical trials, prospective, retrospective observational studies, case-control studies, and cohort studies. The primary outcomes were blood loss and the need for a transfusion, and secondary outcomes were hemoglobin, hematocrit, and adverse effects. We assessed the risk of bias with the Cochrane Collaboration tool. We performed the statistical analysis in R and reported information about the mean difference (MD) with a 95% confidence interval (CI). We evaluated heterogeneity with the I2 test. We produced forest plots to show the amount of evidence available for each outcome and made subgroup analyses. RESULTS We included 11 studies in qualitative and quantitative analysis accounting for 752 patients. In general, the risk of all bias was assessed as low for non-randomized studies, and we found high performance and detection bias in one randomized study. TXA significantly reduced blood loss and need for transfusion compared to placebo/no intervention with an MD of -15.47 (95%CI -23.82, -7.11) and -8.18 (95%CI -12.24, -4.11), respectively. These differences were maintained regardless of the type of study, secondary outcomes also favored TXA, and there was no report of adverse effects. CONCLUSIONS TXA reduces blood loss and the need for transfusion when compared to placebo/no intervention. The available studies on this topic suggest its use in these patients and its implementation in surgery protocols.

Abstract
ABSTRACT Minimally-invasive endoscopic-assisted craniectomy (EAC) achieves similar functional and cosmetic outcomes, whereas reducing morbidity risk that is often associated with complex cranial vault reconstruction. Antifibrinolytics (AF) usage to limit blood loss and transfusion requirements during complex cranial vault reconstruction has been studied extensively; however, studies are limited for AF therapy in EAC. The aim of this single-center retrospective observational cohort pilot study was to evaluate whether the use of AF was associated with reduced blood loss in infants undergoing EAC. The authors hypothesized that there would be no difference in blood loss between patients who received AF and those that did not receive AF during EAC. Non-syndromic patients who underwent single-suture EAC were retrospectively evaluated. Primary outcome measure was intraoperative calculated blood loss (mL/kg). Secondary outcome measures included perioperative red blood cells transfusion volumes, number of blood donor exposures, and pediatric intensive care unit and total hospital length of stay. Study cohort demographic and outcome data were analyzed; Fisher exact test was used for categorical data, Student t test was used for continuous data. A P value of < 0.05 was considered statistically significant. Forty-nine EAC patients were included in the study with 34 patients in the AF cohort and 15 patients in the non-AF cohort. There were no significant differences in demographics between the 2 groups. Additionally, there was no significant difference in intraoperative calculated blood loss or any secondary outcome measure. In our single-suture EAC study cohorts, AF administration was not associated with a decrease in blood loss when compared to those that did not receive AF therapy.

Abstract
ABSTRACT Blood loss is a potential cause of morbidity and mortality in craniosynostosis surgery. Recent reports have suggested that the use of tranexamic acid (TXA), an antifibrinolytic agent, mitigates this blood loss. A retrospective cohort study of patients undergoing craniosynostosis surgery at a tertiary craniofacial hospital in Sydney was undertaken. Primary outcomes were blood loss and transfusion requirements. Two groups were compared: those who received intravenous prophylactic TXA and those who underwent surgery without TXA. Statistical analysis was performed with Student t test and the Mann-Whitney U test for nonparametric results. We identified 206 patients who underwent craniosynostosis surgery over an 8 year period; 78 control patients and 128 patients that received TXA. Tranexamic acid was found to result in a weight-adjusted calculated blood loss mean difference of 9.6 ml/kg across all procedures (P = 0.0332 95% confidence interval 0.7734-18.4266). The actual blood loss reduction achieved with TXA was 6.7 ml/kg in spring cranioplasties, compared to 15.2 ml/kg in fronto-orbital remodeling procedures. There was a statistically and clinically significant reduction in postoperative transfusion incidence, with transfusions required in 27% of controls and 6% of TXA patients (P < 0.0001). The number needed to treat to prevent giving a unit of blood postoperatively was 4.8. There wxere no incidences of TXA-specific complications. This study found that TXA is a safe and effective method of decreasing blood loss and transfusion requirements in patients undergoing craniosynostosis surgery. The clinical benefit of TXA is particularly evident in the more invasive craniosynostosis surgeries.

Abstract
ABSTRACT Blood loss is a potential cause of morbidity and mortality in craniosynostosis surgery. Recent reports have suggested that the use of tranexamic acid (TXA), an antifibrinolytic agent, mitigates this blood loss. A comprehensive systematic review and subsequent meta-analysis was undertaken, with the view to clarify the effectiveness of TXA in reducing blood loss and transfusion requirements in craniosynostosis surgery. Medline and PubMed databases were searched using the preferred reporting items for systematic reviews and meta-analyses technique, and 7003 articles were assessed based on predefined selection criteria. Seven trials were identified, of which 2 were randomized controlled trials and the remainder retrospective cohort studies. All trials were assessed using the Jadad and strengthening the reporting of observational studies in epidemiology scores. The meta-analysis found a clear statistical reduction in blood loss in those patients who received TXA perioperatively, with a combined blood loss reduction of 7.06 ml/kg (95% confidence interval -8.97 to -5.15, P < 0.00001). The blood loss reduction was found to extrapolate to a reduction in perioperative transfusion requirements by 8.47 ml/kg in this cohort (95% confidence interval -10.9 to -6.04, P < 00001). There were no TXA-related adverse outcomes recorded in the 258 patients who received TXA across all trials. The trials included in this meta-analysis were limited by underpowered population sizes and significant heterogeneity in blood loss recording techniques. Further, there was significant heterogeneity amongst operations performed. The current literature appears to support the use of TXA in craniosynostosis surgery, but further high quality randomized controlled trials are indicated, ideally including a subgroup analysis between the operations performed.

Abstract
Objective The aim of the present study was to evaluate and select the optimal dosage of tranexamic acid (TXA) to reduce blood loss during cleft palate surgery in children. Materials and Methods This randomized double-blind clinical trial was performed on 80 children under 3 years of age that were candidates for cleft palate surgery. These children were divided into four groups as follows: the first, second, and third groups received 5, 7.5, and 10 mg/kg of TXA, respectively. Moreover, the fourth group was considered as the control group. Before induction of anesthesia and then every 15 min during the surgery, some parameters such as mean arterial pressure, heart rate, SpO2, and ETCO2 were recorded. Moreover, the amount of blood loss during the surgery, the level of surgeon's satisfaction, and incidence rate of complications were assessed and recorded. Results The amount of blood loss during the surgery in TXA groups receiving dosages of 5, 7.5, and 10 mg/kg with the means of 63.75 ± 10.62, 61.25 ± 15.03, and 61.00 ± 14.29, respectively, was significantly lower than that of the control group with the mean of 92.25 ± 19.83 (P < 0.001). Moreover, no significant difference was found between the three groups receiving TXA dosages in terms of the amount of blood loss, the level of surgeon's satisfaction (P > 0.05). Conclusion According to the results of the present study, all three dosages of TXA had a significant role in reducing blood loss in cleft palate surgery. Given the potential for increased risk of side effects from the drug, it seems safe to use the minimal dosage of this drug to control and reduce blood loss during cleft palate surgery in children <3 years of age.

Abstract
INTRODUCTION Craniosysnostosis surgical corrections are routine procedures in the pediatric neurosurgical field. However, these procedures result in significant blood loss. Tranexamic acid (TXA) is an antifibrinolytic drug, which has demonstrated a significant reduction in perioperative blood loss in many pediatric surgical procedures such as cardiac surgery and scoliosis surgery. We conducted a systematic review to evaluate protocols of TXA use in pediatric craniosynostosis procedures and its effect on intraoperative blood loss and transfusions. MATERIAL AND METHODS A comprehensive literature review of the National Library of Medicine (PubMed) database was performed to identify relevant studies. We included any clinical study reporting on blood loss or blood transfusion for pediatric craniosynostosis surgery with intraoperative use of tranexamic acid, with the following limits: publication date from inception to May 2019; reports in English. RESULTS Thirteen studies were eligible for our review. Of the 13 studies, 4 were prospective, randomised, double-blind controlled trials, 9 were retrospective studies, tailored as a "before-after" studies, comparing blood loss and transfusion without/with TXA. TXA significantly decreases the number and volume of packed red blood cell transfusions and the rate of transfusion in children undergoing craniosynostosis surgery. Significantly fewer fresh frozen plasma transfusions were required in the TXA groups in 2 randomised studies. Length of stay in hospital was significantly lower with the use of TXA in three studies. Advantages of TXA administration also include an excellent patient tolerance of side effects, ease of administration and low cost. CONCLUSION TXA significantly reduces blood loss and the need for transfusions in children undergoing craniosynostosis surgery. TXA administration should be a routine part of strategy to reduce blood loss and limit transfusions in these procedures.

Abstract
In the surgical management of craniosynostosis, there is a high red blood cell (RBC) transfusion burden due to the small blood volume of the patients combined with significant blood loss that can occur with open surgery (OS). Tranexamic acid (TXA) is an antifibrinolytic which has been shown to decrease such a burden in particular surgeries. The aim of this study was to compare the operative outcomes of craniosynostosis OS which did and did not utilize TXA. Searches of 7 electronic databases from inception to February 2018 were conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. There were 206 articles screened against selection criteria for inclusion. Relevant data were extracted and analyzed using meta-analysis of proportions. A total of 9 comparative studies were included for meta-analysis. Compared with the control cohort, craniosynostosis OS utilizing TXA demonstrated significantly lower intraoperative RBC transfusion volumes (mean difference, -8.25 mL/kg; P < 0.001), blood loss (mean difference, -10.96 mL/kg; P < 0.001) and postoperative RBC transfusion incidence (odds ratio, OR, 0.12; P = 0.005). Fresh frozen plasma and crystalloid transfusion, operation time, length of stay, and complications were not significantly different with TXA use. Based on the comparative evidence currently available, TXA significantly decreased RBC transfusion burden during craniosynostosis OS without operative compromise. There is significant heterogeneity in reported TXA regimes in the literature. Future studies that are larger, randomized, and account for these factors will further enhance the authors' understanding.

J Oral Maxillofac Surg 2019; 77:1245-1260. [PMID: 30796910 DOI: 10.1016/j.joms.2019.01.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 01/19/2019] [Accepted: 01/21/2019] [Indexed: 12/12/2022]
Abstract
PURPOSE Use of antifibrinolytic drugs in craniofacial and orthognathic surgery seems quite promising and has strong advocates. However, supporting evidence is controversial and limited by a small sample of individual studies. We sought to systematically review and meta-analyze the available data regarding the role of preoperative or intraoperative antifibrinolytic drugs (eg, tranexamic acid, aprotinin, or aminocaproic acid) in craniofacial and orthognathic surgery. MATERIALS AND METHODS We searched PubMed, Scopus, Embase, the Cochrane Library, and Web of Science through April 19, 2018, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcomes of interest included the volume of blood loss, volume of transfusions, and operative time. A meta-analysis was performed with a random-effects model using Review Manager (RevMan) software (The Cochrane Collaboration, Copenhagen, Denmark). RESULTS We identified 32 eligible studies with 749 patients undergoing craniofacial surgery and 546 undergoing orthognathic surgery. Meta-analysis showed that antifibrinolytic use led to statistically significant decreases in blood loss and blood transfusions for craniofacial procedures in adult or pediatric patients and to significantly less blood loss during orthognathic surgical procedures. Operative time did not significantly differ for either type of surgery. CONCLUSIONS Antifibrinolytics can significantly reduce blood loss in craniofacial surgical procedures including pediatric craniosynostosis and adult rhinoplasties and in orthognathic surgical procedures, as well as transfusion requirements in pediatric craniofacial surgical procedures. However, the clinical significance of the medications is still questionable because of the relative paucity of information on adverse effects and the usual small volume loss during those operations.

Abstract
BACKGROUND Minimally invasive approaches for the treatment of single-suture craniosynostosis are sometimes touted as equivalent to cranial vault reconstruction. While techniques for sagittal synostosis have been reviewed previously, evidence regarding open and less invasive surgical techniques for metopic, coronal, and lambdoid synostosis has yet to be reviewed. METHODS Systematic searches were performed using Embase.com and PubMed. Included studies reported short- or long-term outcomes, compared at least 2 standard techniques, discussed single-suture coronal, metopic, or lambdoid craniosynostosis, and enrolled at least 20 study participants. Two authors screened titles and abstracts, and also performed full text review and data extraction. Given heterogeneous outcomes, qualitative synthesis was performed after data extraction. RESULTS The search strategy yielded 2348 articles. Of these, 313 were removed as duplicates, and 1935 were excluded during title/abstract review. After full text review of 100 articles, 19 were selected for data extraction. The heterogeneity of outcomes precluded meta-analysis and required qualitative synthesis. While short-term outcomes indicated decreased morbidity of minimally invasive techniques, only 2 articles presented long-term reoperation rates. One study reported higher reoperation rates in the less invasive technique, and the second reported no reoperations in the median follow-up period of 33 months. CONCLUSION Studies comparing long-term outcomes between different surgical techniques for single-suture craniosynostosis remain deficient. The development of standardized outcome measures is essential, and prospective, multicenter studies are necessary to assess the long-term efficacy of these procedures.

Abstract
BACKGROUND Prevention of blood loss is a chief consideration in plastic and reconstructive surgery. The antifibrinolytic drugs tranexamic acid and ε-aminocaproic acid have emerged as promising agents to reduce both perioperative blood loss and transfusion requirements. However, published reports in the plastic surgery literature are lacking. The authors sought to summarize the current knowledge of the use of antifibrinolytics in plastic surgery by reviewing the existing literature for clinical outcomes and recommendations. METHODS A systematic review of the PubMed, Cochrane, and Google Scholar databases was conducted for publications examining the use of antifibrinolytics in plastic surgery. Studies were abstracted for procedure type, antifibrinolytic dose, time and mode of administration, blood loss, transfusion requirements, and complications. RESULTS Thirty-three studies were deemed eligible for inclusion, comprising a total of 1823 patients undergoing plastic surgical procedures with tranexamic acid (n = 1328) and/or ε-aminocaproic acid (n = 495). CONCLUSIONS Tranexamic acid and ε-aminocaproic acid are widely used to reduce blood loss and transfusion requirements in craniofacial and orthognathic surgery, without an increased risk of adverse events. Intravenous administration is most commonly used, although topical formulations show similar efficacy with a reduced systemic distribution. Tranexamic acid has also emerged as a promising agent in aesthetic surgery and burn care, due to its favorable safety profile and role in reducing blood loss, achieving an improved surgical field, and reducing edema and ecchymosis. Further investigation of these agents in the fields of burn care, aesthetic surgery, and microsurgery is warranted to standardize protocols for clinical use.

Abstract
PURPOSE The aim of this study was to compare the outcome of intracranial volume (ICV) and cephalic index (CI) between two different techniques for surgical therapy of sagittal synostosis. MATERIAL AND METHODS Between 2011 and 2015, all patients scheduled for surgical therapy of sagittal synostosis were consecutively enrolled. All patients younger than 6 months underwent early extended strip craniectomy (ESC group), and patients older than 6 months underwent late modified pi-procedure (MPP group). To measure ICV and CI, data acquisition was performed via three-dimensional photogrammetry, 1 day before (T0) and between 10 and 12 weeks after surgery (T1). Results were compared with an age-matched reference group of healthy children. Perioperative parameters, as duration of surgery and the amount of blood loss of both surgical procedures were analyzed. RESULTS A total of 85 patients were enrolled. Of the patients, 48 underwent an extended strip craniotomy with parietal osteotomies and biparietal widening and 37 patients underwent a late modified pi-procedure. There was no significant difference between the ESC group and the MPP group regarding the efficacy of improving CI (p > 0.05). Both techniques were able to normalize CI and to improve head shape. ICV was normal compared to age-matched norm-groups with both techniques, pre- and postoperatively. However, duration of the surgical procedure and calculated blood loss were significantly lower in the ESC group (p < 0.05). CONCLUSION ESC and MPP were effective techniques to normalize cephalic index (CI) and improve head shape at their recommended time of surgery. Measurement of ICV and CI with 3D photogrammetry is a valid method to objectively evaluate patients before and after surgery without exposing pediatric patients to ionizing radiation.

Abstract
BACKGROUND Antifibrinolytic therapy significantly decreases blood loss and transfusion in pediatric cranial vault reconstructive surgery; however, concern regarding the side effects profile limits clinical use. AIMS The aim was to utilize the Pediatric Craniofacial Surgery Perioperative Registry database to identify the safety profile of antifibrinolytic therapy for cranial vault reconstructive surgery by reporting the incidence of adverse events as they relate to exposure to tranexamic acid and aminocaproic acid compared to no exposure to antifibrinolytics. METHODS The database was queried for cases of open cranial vault reconstructive surgery. Less invasive procedures such as neuro-endoscopic and spring-mediated cranioplasties were excluded. The outcomes evaluated included any perioperative neurological adverse event including seizures or seizure-like movements and thromboembolic events. RESULTS Thirty-one institutions reported a total of 1638 cases from 2010 to 2015. Total antifibrinolytic administration accounted for 59.5% (tranexamic acid, 36.1% and aminocaproic acid, 23.4%), with 40.5% not receiving any antifibrinolytic. The overall incidence of postoperative seizures or seizure-like movements was 0.6%. No significant difference was detected in the incidence of postoperative seizures between patients receiving tranexamic acid and those receiving aminocaproic acid [the odds ratio for seizures being 0.34 (95% confidence interval: 0.07-1.85) controlling for American Society of Anesthesia (ASA) physical class] nor in patients receiving antifibrinolytics compared to those not administered antifibrinolytics (the odds ratio for seizures being 1.02 (confidence interval 0.29-3.63) controlling for ASA physical class). One complicated patient in the antifibrinolytic group with a femoral venous catheter had a postoperative deep venous thrombosis. CONCLUSIONS This is the first report of an incidence of postoperative seizures of 0.6% in pediatric cranial vault reconstructive surgery. There was no significant difference in postoperative seizures or seizure-like events in those patients who received the tranexamic acid or aminocaproic acid vs those that did not. This report provides evidence of the safety profile of antifibrinolytic in children having noncardiac major surgery. Caution should prevail however in using antifibrinolytic in high-risk patients. Antifibrinolytic dosage regimes should be based on pharmacokinetic data avoiding high doses.

Abstract
INTRODUCTION Our center previously reported low transfusion rates for craniosynostosis surgery by two experienced neurosurgeons using standard intraoperative techniques and acceptance of low hemoglobin levels. This study evaluated whether low rates were maintained over the last 10 years and if a less experienced neurosurgeon, trained in and practicing in the same environment, could achieve similar outcomes. METHODS All craniosynostosis operations performed in children between 2004 and 2015 were reviewed retrospectively. Transfusion rates were calculated. Analyses examined the relationship of transfusion to craniosynostosis type, surgical procedure, redo operation, surgeon, and perioperative hemoglobin levels. RESULTS Two hundred eighteen patients were included: 71 open sagittal, 28 endoscopic-assisted sagittal, 32 unicoronal, 14 bicoronal, 42 metopic, and 31 multisuture. Median age at operation was 9.1 months. Overall transfusion rate was 24 %: 17 % open sagittal, 7 % endoscopic-assisted sagittal, 6 % unicoronal, 21 % bicoronal, 45 % metopic, and 45 % multisuture. The timing of transfusions were 75, 21, and 4 % for intraoperative, postoperative, and both, respectively. Patients not receiving transfusion had a mean lowest hemoglobin of 87 g/l (range 61-111) intraoperatively and 83 g/l (range 58-115) postoperatively. Mean lowest hemoglobin values were significantly lower in those necessitating intraoperative (75 g/l, range 54-102) or postoperative (59 g/l, range 51-71) transfusions. There was no significant difference in transfusion rate between less and more experienced surgeons. There were no cardiovascular complications or mortalities. CONCLUSION In craniosynostosis surgery, reproducible, long-term low blood transfusion rates were able to be maintained at a single center by careful intraoperative technique and acceptance of low intraoperative and postoperative hemoglobin levels in hemodynamically stable patients. Furthermore, low rates were also achieved by an inexperienced neurosurgeon in the group. This suggests that these results may be achievable by other neurosurgeons, who follow a similar protocol.

Abstract
Background Intraoperative tranexamic acid (TXA) administration has been used to abate blood loss in a variety of surgical procedures. Several recent studies have supported its efficacy in reducing transfusion requirements in pediatric cranial vault reconstruction (CVR). Objective To conduct a retrospective chart review to determine whether a significant reduction in packed red blood cell (PRBC) and fresh frozen plasma (FFP) transfusions exists when TXA is used. Methods A retrospective cohort study of 28 patients who underwent CVR for sagittal craniosynostosis was performed. Transfusion requirements for 14 patients who did not receive TXA were compared with 14 patients who did. Predictors of increased blood product transfusion were also studied. Results Total volume of PRBC transfusion was reduced by 50% with the use of TXA (P=0.004) with a 34% reduction in intraoperative PRBC transfusion (P=0.017) and a 67% reduction in postoperative PRBC transfusion (P<0.001). Total volume of FFP transfusion was reduced by 46% (P=0.002) and postoperative FFP transfusion was reduced by 100% (P=0.001). The use of TXA was associated with a lower total volume of PRBC (P=0.003) and FFP (P=0.003) transfusions. Older patient age was associated with lower total volume of PRBC transfused (P=0.046 and P=0.002), but not with FFP (P=0.183 and P=0.099) transfusion volumes. Increasing patient weight was associated with lower PRBC (P=0.010 and P=0.020) and FFP (P=0.045 and P=0.016) transfusion volumes. Conclusion TXA decreased blood product transfusion requirements in patients undergoing CVR for sagittal craniosynostosis, and should be a routine part of the strategy to reduce blood loss in these procedures.

Abstract
OBJECTIVE To assess the effect of tranexamic acid on the quality of the surgical field. DESIGN Prospective, randomized, double-blind study. SETTING Institutional, tertiary referral hospital. PARTICIPANTS American Society of Anesthesiologists physical status class I patients, aged 8 to 60 months with Group II or III (Balakrishnan's classification) clefts scheduled for cleft palate repair. INTERVENTIONS Children were randomized into two groups. The control group received saline, and the tranexamic acid group received tranexamic acid 10 mg/kg as a bolus, 15 minutes before incision. MAIN OUTCOME MEASURES Grade of surgical field on a 10-point scale, surgeon satisfaction, and primary hemorrhage. RESULTS Significant improvements were noted in surgeon satisfaction and median grade of assessment of the surgical field (4 [interquartile range, 4 to 6] in the control group vs. 3 [interquartile range, 2 to 4] in the test group; P = .003) in the tranexamic acid group compared to the control group. CONCLUSION Preincision administration of 10 mg/kg of tranexamic acid significantly improved the surgical field during cleft palate repair.

Abstract
OBJECT Children with craniosynostosis may require cranial vault remodeling to prevent or relieve elevated intracranial pressure and to correct the underlying craniofacial abnormalities. The procedure is typically associated with significant blood loss and high transfusion rates. The risks associated with transfusions are well documented and include transmission of infectious agents, bacterial contamination, acute hemolytic reactions, transfusion-related lung injury, and transfusion-related immune modulation. This study presents the Children's Hospital of Richmond (CHoR) protocol, which was developed to reduce the rate of blood transfusion in infants undergoing primary craniosynostosis repair. METHODS A retrospective chart review of pediatric patients treated between January 2003 and Febuary 2012 was performed. The CHoR protocol was instituted in November 2008, with the following 3 components; 1) the use of preoperative erythropoietin and iron therapy, 2) the use of an intraoperative blood recycling device, and 3) acceptance of a lower level of hemoglobin as a trigger for transfusion (< 7 g/dl). Patients who underwent surgery prior to the protocol implementation served as controls. RESULTS A total of 60 children were included in the study, 32 of whom were treated with the CHoR protocol. The control (C) and protocol (P) groups were comparable with respect to patient age (7 vs 8.4 months, p = 0.145). Recombinant erythropoietin effectively raised the mean preoperative hemoglobin level in the P group (12 vs 9.7 g/dl, p < 0.001). Although adoption of more aggressive surgical vault remodeling in 2008 resulted in a higher estimated blood loss (212 vs 114.5 ml, p = 0.004) and length of surgery (4 vs 2.8 hours, p < 0.001), transfusion was performed in significantly fewer cases in the P group (56% vs 96%, p < 0.001). The mean length of stay in the hospital was shorter for the P group (2.6 vs 3.4 days, p < 0.001). CONCLUSIONS A protocol that includes preoperative administration of recombinant erythropoietin, intraoperative autologous blood recycling, and accepting a lower transfusion trigger significantly decreased transfusion utilization (p < 0.001). A decreased length of stay (p < 0.001) was seen, although the authors did not investigate whether composite transfusion complication reductions led to better outcomes.

Abstract
PURPOSE Tranexamic acid (TXA) is prescribed for short term management of haemorrhage. It is also administered prophylatically in surgeries where blood loss is anticipated. Tranexamic mouth washes are also used in oral surgical procedures for patients with coagulopathies. The purpose of this study was to assess the efficiency of the usage of tranexamic acid on reduction of haemorrhage in maxillo mandibular trauma cases. MATERIALS AND METHODS Twelve consecutive male patients, between the ages 20-40 years, with multiple fractures of the facial bones, were included in this study. Six patients were administered either IV tranexamic acid (10 mg/kg- Group 1)and another six placebo (IV normal saline- Group 2) just before induction of anaesthesia. All patients were operated by the same surgical team, using the same standard techniques and the same anaesthetist and the same drugs were used during the surgery. Hypotension was induced for further reduction of intra operative blood loss. Intra and post-operative blood loss, operation time, transfusion of blood products, pre- and post-operative haemoglobin, number of days of hospitalisation and blood count were recorded for both groups. RESULTS Tranexamic acid significantly reduced the volume of blood loss during the surgery when compared with the control group (489.17± 106.7 mL vs 900.83 ± 113.7 mL). Considering the duration of operation and the treatment groups only, the mean total blood loss in the control group was 411.67 mL more than that in the tranexamic acid group. None of the patients of the TXA group required blood transfusion post-operatively. There was no difference in the length of hospital stay between the 2 groups. Two of the patients of the saline group required blood transfusion post-surgery due to significant drop in haemoglobin. The average drop in haemoglobin was 2 ± 1.4 in the tranexamic group and 4 ± 1.09 in the saline group. CONCLUSION Pre-operative intravenous bolus administration of tranexamic acid at 10 mg/kg reduces blood loss compared with placebo during the surgery.
