Sakhariya SV, Waknis PP, Setiya S, Tidke SS. Effect of Induced Hypotensive Anesthesia and Normotensive Anesthesia on Intraoperative Blood Loss During Orthognathic Surgery: A Systematic Review. J Maxillofac Oral Surg 2024; 23:1127-1137. [PMID: 39376768 PMCID: PMC11456043 DOI: 10.1007/s12663-023-02034-y] [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: 04/03/2023] [Accepted: 10/18/2023] [Indexed: 10/09/2024] Open
Abstract
Background Orthognathic surgery involves significant bleeding from both soft tissues and bones due to rich blood supply to areas involved. In addition, limited access along with poor visibility and difficulty to isolate or ligate adds to the problem of bleeding during surgery. As a result, to counter drawbacks of intraoperative bleeding, method of induced hypotension stands out. Hypotensive anesthesia is a method through which blood pressure is decreased in a controlled manner. Various studies have been conducted that compared multiple methods to reduce intraoperative blood loss and improve visibility of surgical field. Hence, need for a systematic review to study the effects of hypotensive anesthesia on intraoperative blood loss, duration of the surgery and quality of surgical field. Methods An electronic search was conducted to cumulate data from PubMed, Google scholar and institutional library from 2000 to 2020. In addition, bibliographies of included studies were hand searched to identify potentially eligible studies to append to the data and reach a conclusion. Results Comparative study of the data available indicates that controlled hypotension during general anesthesia is safe for young healthy patients undergoing orthognathic surgeries. Conclusion This information could be of key importance to aid in reducing intraoperative blood loss and which improves the observability of the surgical field; lessen the chances of need for blood transfusion; and eventually shorten the length of stay in hospital.

J Maxillofac Oral Surg 2024; 23:229-234. [PMID: 38601251 PMCID: PMC11001797 DOI: 10.1007/s12663-024-02119-2] [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: 08/10/2022] [Accepted: 01/19/2024] [Indexed: 04/12/2024] Open
Abstract
Background Tranexamic acid (TXA) is utilized frequently in orthognathic surgery to limit blood loss and improve surgical field visualization. This antifibrinolytic has been proven effective with use of concomitant hypotensive anesthesia. Despite proven efficacy, there is a recent push to avoid perioperative hypotensive anesthesia due to risks of organ hypoperfusion, cardiac ischemia and postoperative nausea. Aims The aim is to study the efficacy and safety of utilizing TXA without controlled hypotensive anesthesia. Methods The authors identified two cohorts of subjects that underwent bimaxillary orthognathic surgery both with and without TXA administration and compared operative and perioperative variables. A retrospective analysis was completed evaluating intraoperative MAP measurements in subjects treated both with and without TXA using descriptive and bivariate analysis. Results and conclusion Sixty-three subjects met inclusion criteria. The TXA cohort experienced 11.5% less time under hypotensive anesthesia when compared to the group that did not receive TXA. Additionally, surgical length was decreased by more than 28 min when subjects received TXA. No subjects required a blood transfusion or experienced any TXA-related complications. Given the recommendations to limit hypotensive anesthesia perioperatively, TXA is a useful adjunct in orthognathic surgery to limit controlled hypotensive anesthesia.

Abstract
OBJECTIVE This study aimed to comprehensively review the literature and provide a practical guide for optimizing drug regimens and supplementation related to orthognathic surgery. METHODS The authors conducted a thorough review of the existing literature, following the PRISMA-ScR guidelines. Various types of studies except case reports and reviews were included. The study applied specific inclusion criteria, focusing on perioperative and/or postoperative drugs, medications, or supplementation related to orthognathic surgery. RESULTS This guide included 78 studies on various medications in orthognathic surgery. It encompasses clinical trials, cohort studies, cross-sectional studies, prospective and retrospective studies. The topics covered include antibiotics, analgesics, corticosteroids, antiemetics, hemostatic agents, local anesthetics, herbal medicine, and botulinum toxin. Pain and edema control involved specific medications, while local anesthesia utilized ropivacaine and bupivacaine. The guide also discusses mineral and vitamin supplementation. The effectiveness of hemostatic agents and antiemetics was highlighted. CONCLUSION Pain management, reduced swelling, enhanced wound healing, and faster recovery are among the advantages. In addition to the standard drugs and medications, the inclusion of vitamin and mineral supplements, tranexamic acid, postoperative anesthetic blocks, and preemptive antiemetics is anticipated to offer various benefits in orthognathic surgery, despite the limited available evidence.

Abstract
Objectives Orthognathic surgery is a corrective intervention for maxillofacial deformities. Bleeding is a major concern for oral and maxillofacial surgeons. Various agents, such as hemocoagulase, tranexamic acid, and aprotinin have been developed to reduce intraoperative bleeding and transfusion requirements. Therefore, in this study we aimed to investigate the effects of hemocoagulase and tranexamic acid, as well as their simultaneous use, to reduce bleeding during orthognathic surgery. Patients and. Methods This retrospective study included patients who had undergone simultaneous orthognathic surgery of the maxilla and mandible between January 2013 and September 2022 and were classified into three groups based on drugs administered: hemocoagulase (Botropase), tranexamic acid, and a combination of both drugs. We recorded patient age, sex, weight, blood loss, and duration of surgery. Red blood cell (RBC), hemoglobin, hematocrit, and platelet levels were measured before, immediately after, and one day after surgery. Results No statistically significant differences were found in blood loss, RBC, hemoglobin, hematocrit, or platelet levels between any of the groups. There were no differences in the drug effects between Le Fort I and bilateral mandibular sagittal split osteotomies, with or without double genioplasty. However, there were significant reductions in RBC, hemoglobin, hematocrit, and platelet levels during genioplasty. Conclusion Tranexamic acid, hemocoagulase, and their combination had similar efficacy in patients who underwent Le Fort Ⅰ and bilateral mandibular sagittal split osteotomies with and without genioplasty.

Abstract
The midface skeleton provides structural scaffolding to the middle third of the face. Complications associated with fracture repair in these regions can result from incomplete, inaccurate, or delayed assessment, poor initial and subsequent reduction and fixation, infection, uncontrolled hemorrhage, hardware failure and associated soft tissue injuries. A systematic approach to managing the patient with facial trauma that includes Acute Trauma Life Support principles, early reconstruction, and precise reduction and fixation is essential to reducing the short-term and long-term risks of complications.

Abstract
STUDY DESIGN Systematic mapping review AIM AND SCOPE: The objective of this mapping review was to identify, describe, and organize clinical research currently available from systematic reviews and primary studies regarding co-interventions and different surgical modalities used in orthognathic surgery (OS) and their outcomes. METHODS Systematic reviews (SRs), randomized controlled trials, and observational studies that evaluated perioperative OS co-interventions and surgical modalities were identified in an exhaustive search of MEDLINE, EMBASE, Epistemonikos, Lilacs, Web of Science, and CENTRAL. Grey literature was also screened. RESULTS Included were 35 SRs and 253 primary studies, 103 from SRs, and another 150 identified in our search. Overall, SR quality was rated as critically low, with only two SRs rated as of high quality. 19 questions on population, interventions, comparisons, and outcomes (PICO) extracted from the SRs focused on osteosynthesis methods, surgical cutting devices, and use of antibiotics, corticosteroids, and induced hypotension. Also identified were 15 research gaps. Evidence bubble maps were created to graphically depict the available evidence. CONCLUSION Future high-quality research, both primary and secondary, is needed to address the knowledge gaps identified in this systematic mapping review.

Abstract
BACKGROUND In facial contour surgery, due to the narrow field of vision in the oral approach and the abundant blood supply to the maxillofacial area, hemostasis is not easy. The purpose of this study was to evaluate the hemostatic effect of soluble hemostatic gauze. METHODS We organized a prospective randomized study of 282 patients receiving facial contouring surgery (4 types of procedures in total) during 2016.1.1 to 2018.12.30. For each type of procedure, patients were randomly divided into study group (received hemostatic gauze) and control group (received sterile gauze). Two groups were compared for each type of procedure regarding 5 major perioperative variables: intraoperative blood loss, operation time, 24-hour postoperative drainage volume, total postoperative drainage volume, and postoperative drainage time. Correlation between variables was analyzed. RESULTS Compared with control group, the study group had higher amount of intraoperative blood loss in mandibular angle ostectomy (MAO) (P < .01) and mandibular angle-body-chin curved ostectomy procedures (P < .05), less total postoperative drainage volume in MAO (P < .01) but not in malarplasty with MAO and partial masseter muscle resection along with MAO procedures. No significant difference was observed between respective study and control groups regarding operation time, 24-hour postoperative drainage volume, and postoperative drainage time in any of the 4 types of surgery. In all 4 types of procedures, a strongly positive correlation was observed between total drainage volume and 24-hour drainage volume in both the study and control groups (r: 0.88-0.97, P < .01). CONCLUSION The effect of hydroxyethyl cellulose soluble hemostatic gauze on hemostasis in facial contouring surgery is associated with the type of surgery, which can reduce the risk of postoperative bleeding in MAO. However, for surgery with relatively large amount of intraoperative and postoperative bleeding, the hemostatic gauze had a limited postoperative hemostasis efficacy, which needs further evaluation.

Abstract
Background: Orthognathic surgery requires red blood cell (RBC) transfusions more frequently than other oral and maxillofacial surgeries. The purpose of this study was to identify reliable predictors for RBC transfusion during bimaxillary orthognathic surgery (BOS). Methods: This retrospective study reviewed 1,616 electronic medical records of patients who underwent BOS during a 5-year period at Seoul National University Dental Hospital. The perioperative variable data were collected from electronic medical records and analyzed by dividing patients into the two groups (non-transfusion and transfusion group). Results: Of the 1,616 patients, 1,311 patients were excluded. The remaining 305 patients were divided into non-transfusion (NTF, n = 256) and transfusion (TF, n = 49) groups. Univariate logistic regression analysis revealed that age, body mass index, the presence of several adjunctive surgeries (including genioplasty, extraction, and mandibular angle reduction), preoperative hemoglobin (Hb) and prothrombin time, surgical time, amount of fluid infusion and blood loss, and mean pulse rate during surgery were significant factors predicting RBC transfusion. Multivariate logistic regression analysis revealed that preoperative Hb and blood loss amount during surgery were significantly related to RBC transfusion in BOS patients. Conclusion: Since blood loss amounts could not be measured preoperatively, we found that the independent predictor associated with RBC transfusion during BOS was a low preoperative Hb level.

Abstract
The aim of this prospective observational study was to investigate the parameter 'hidden blood loss' (HBL) in the context of orthognathic surgery, incorporating undetected bleeding volumes occurring intra- and postoperatively. Orthognathic bleeding volumes were recorded at three different time points. At the end of the operation the visible intraoperative blood loss (VBL) was measured. Additionally, the perioperative blood loss was calculated 24 h and 48 h postoperatively using the 'haemoglobin balance method'. Analysis of the HBL was based on the difference between the visible intraoperative blood loss (VBL) and calculated blood loss (CBL), determined 48 h after surgery. 82 patients (male 33, female 49) were included in this study, of whom 41 underwent bimaxillary surgery and of whom 41 underwent Bilateral Sagittal Split Osteotomy (BSSO). Statistically significant differences with reference to the absolute bleeding volumes were found when comparing the two treatment modalities. In terms of HBL, a bleeding volume of 287.2 ml (±265.9) in the bimaxillary group and 346.9 ml (±271.3) in the BSSO cohort was recorded. This accounted for 32.2% (bimaxillary surgery) and 62.6% (BSSO) of the CBL after 48 h (BIMAX vs. BSSO, p < 0.001). HBL is a valuable adjunct to record within the perioperative management of orthognathic surgery to further improve patient safety and postoperative outcomes.

Abstract
PURPOSE In the past, both tranexamic acid and dexmedetomidine have been used separately to decrease intraoperative blood loss during orthognathic surgery. However, their combined use in the same setting has never been prospectively evaluated. The present study was conducted to evaluate the effect of tranexamic acid on operative field visibility and blood loss during orthognathic surgery after dexmedetomidine-induced hypotensive anesthesia. PATIENTS AND METHODS The present prospective, randomized clinical trial included patients who had undergone orthognathic surgery under general anesthesia. The patients were divided into 2 groups. The dexmedetomidine and tranexamic (DT) group received an intravenous bolus of tranexamic acid (15 mg/kg) and intravenous dexmedetomidine (0.25 to 0.7 μg/kg/hr) as maintenance infusion. The dexmedetomidine (DS) group received only intravenous dexmedetomidine at the same dosage. All the patients received a bolus dose of intravenous dexmedetomidine (1 μg/kg) before the start of anesthesia induction. The operating surgeon rated the quality of the surgical visual field every 15 minutes using the Fromme ordinal scale. Intraoperative blood loss was estimated using the modified gross formula. The operating surgeon's satisfaction was assessed using a Likert scale. Data were analyzed using SPSS, version 22.0 (IBM Corp, Armonk, NY). Kolmogorov-Smirnov tests were used to assess the normality of the measured data, and categorical variables were analyzed using the χ2 or Fischer exact test. RESULTS The study sample included 36 patients, with a mean age of 23.67 ± 11.298 years in the DS group and 20.28 ± 3.286 years in the DT group. Of the patients in the DS and DT groups, 66.66 and 61.11% were male, respectively. No statistically significant differences were found in the baseline characteristics between the 2 treatment groups. The surgeon reported a significantly better surgical visual field in the DT group compared with that in the DS group (P = .001). Also, the intraoperative blood loss significantly less in the DT group (231.11 ± 137.64 mL vs 360.17 ± 187.86 mL; P = .025). CONCLUSIONS Tranexamic acid improved surgical field visibility and reduced intraoperative blood loss when administered in conjunction with dexmedetomidine during orthognathic surgery under controlled hypotensive anesthesia.

Abstract
Introduction Orthognathic surgery can account for a considerable amount of blood loss since the vascularization of maxillofacial region is such that major bleeding can occur. Intra-bony bleed is often involved as a major aspect of blood loss associated with osteotomies, especially LeFort I osteotomy when performed during orthognathic surgery. This study evolved as a result of the increasing concern to attain a clear surgical field and reduce the duration of surgical procedure and the amount of blood loss associated with orthognathic surgery with the use of controlled hypotension. Method Twenty patients planned for undergoing LeFort I osteotomy were randomly allocated into two groups (Group 1-normotensive anesthesia; Group 2-hypotensive anesthesia). The amount of blood loss, mean difference between hemoglobin and hematocrit in the preoperative and postoperative period, and quality of surgical field were evaluated for patients in the two groups. Conclusion Comparative analysis of the various parameters showed a statistically significant improvement in the hypotensive group when compared to normotensive group, although the duration of surgery and postoperative morbidity were not significantly affected when controlled hypotension was used.

Abstract
The efficacy of tranexamic acid in orthognathic surgery remains controversial. We conducted a systematic review and meta-analysis to explore the influence of tranexamic acid on blood loss for orthognathic surgery. We performed a search of PubMed, Embase, Web of science, EBSCO, and Cochrane library databases through October 2017 for randomized controlled trials (RCTs) assessing the effects of tranexamic acid versus placebo on orthognathic surgery. Meta-analysis was performed using the random-effects model. Six RCTs were included in the meta-analysis. Overall, compared with placebo in orthognathic surgery, tranexamic acid administration results in significantly decreased blood loss [mean difference (MD)=-159.73; 95% confidence interval (CI)=-236.42 to -83.03; P<0.0001], and higher postoperative haemoglobin (MD=0.71; 95% CI=0.11 to 1.31; P=0.02), but has no remarkable impact on postoperative haematocrit (MD=1.23; 95% CI=-1.22 to 3.69; P=0.33) and operation time (MD=-2.35; 95% CI=-18.05 to 13.36; P=0.77). In addition, patients with orthognathic surgery need decreased amounts of irrigant fluid (MD=-229.23; 95% CI=-399.63 to -58.83; P=0.008) after using tranexamic acid. We concluded that tranexamic acid promotes the bleeding control in orthognathic surgery.

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 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
Deep vein thrombosis (DVT) is caused primarily by obstruction of blood flow in the deep veins in the lower limbs. It is a form of thrombophlebitis and can be a major cause of morbidity and mortality in hospitalized patients. This report describes an unusual case of DVT in a 21-year-old woman with Class III malocclusion who underwent bimaxillary orthognathic surgery (bilateral sagittal split osteotomy and Le Fort I osteotomy) under general anesthesia. She developed DVT unexpectedly 1 week after surgery, with episodes of sweating and chills in addition to lower limb edema, tenderness, and rigidity. D-dimer laboratory testing and venous Doppler sonography were performed and the DVT diagnosis was confirmed; therefore, the patient was admitted to the intensive care unit for anticoagulant and supportive therapy. Although the incidence rate of thromboembolism in hospitalized patients undergoing oral and maxillofacial surgery is low, it is not an operation without risk of DVT. This complication can cause fatal acute pulmonary thromboembolism and death. This case study illustrates that pharmacologic treatment of menorrhagia with mefenamic acid combined with intraoperative use of tranexamic acid for control of blood loss might put the patient at increased risk of DVT. Hence, maxillofacial surgeons should assess all their patients preoperatively for thromboembolism risk; if they suspect any risk factors in the patient, prompt diagnostic tests and management should be ordered.

Abstract
Purpose: The purpose of this study was to evaluate the efficacy of tranexamic acid (TXA) in reducing blood loss during surgically assisted
rapid palatal expansion (SARPE) procedure. Subjects and Methods: A total of 34 patients (12 male, 22 female) who had been treated surgically under general anesthesia with SARPE
including pterygoid disjunction for transverse maxillary deficiency (TMD) were included in this study. The study group (n=17) received intravenous (IV)
TXA 10 mg/kg as a preoperative bolus; the control group (n=17) received normal saline solution. Preoperative and postoperative haemoglobin and haematocrit
values, intraoperative blood loss, and any blood product transfusion were recorded. Results: Blood loss during SARPE was statistically significantly less in the study group than the control group (p=0.0001). Conclusion: Preoperative IV administration of TXA can effectively control blood loss during when SARPE with pterygoid disjunction is performed.

Abstract
The purpose of this study was to compare the effects of three dosage regimens of intravenous tranexamic acid and normal saline placebo on blood loss and the requirement for transfusion during bimaxillary osteotomy. A prospective, randomized, double-blind, placebo-controlled study was performed. Eighty patients scheduled for elective bimaxillary osteotomy were divided into four groups: a placebo group and three groups receiving a single dose of tranexamic acid 10, 15, or 20mg/kg body weight after the induction of anaesthesia. Demographic data, the anaesthetic time, the operative time, and the experience of the surgical team were similar in the four groups. Patients receiving placebo had increased blood loss compared to those receiving tranexamic acid. No significant difference in blood loss was found among those who received 10, 15, or 20mg/kg body weight of tranexamic acid. There was no significant difference in transfusion requirement, amount of 24-h postoperative vacuum drainage, length of hospital stay, or complications among the four groups. Prophylactic tranexamic acid decreased bleeding during bimaxillary osteotomy. Of the three dosages of tranexamic acid studied, the most efficacious and cost-effective dose to reduce bleeding was 10mg/kg body weight.

Abstract
The aim of this study was to quantitatively evaluate the efficacy of induced hypotensive anesthesia in decreasing facial soft tissue perfusion during orthognathic surgery using laser-assisted indocyanine green fluorescence angiography. This retrospective study involved the evaluation of 16 patients who underwent orthognathic surgery. Data collection included facial tissue perfusion of the bilateral cheeks and chin at normotension and with pharmacologically induced hypotensive anesthesia. There were statistically significant differences in the facial tissue perfusion at normal and depressed levels of blood pressure (P<0.001). This study used an objective measure to demonstrate the long-standing belief that hypotensive anesthesia is efficacious in reducing tissue perfusion in the surgical field. The data suggest that pharmacologically depressing the level of mean arterial pressure by 18% may result in a 41-52% decrease in facial soft tissue perfusion. This study reports a novel method of quantitative analysis.

Abstract
In the field of orofacial surgery, a red blood cell transfusion (RBCT) is occasionally required during double jaw and oral cancer surgery. However, the question remains whether the effect of RBCT during the perioperative period is beneficial or harmful. The answer to this question remains challenging. In the field of orofacial surgery, transfusion is performed for the purpose of oxygen transfer to hypoxic tissues and plasma volume expansion when there is bleeding. However, there are various risks, such as infectious complications (viral and bacterial), transfusion-related acute lung injury, ABO and non-ABO associated hemolytic transfusion reactions, febrile non-hemolytic transfusion reactions, transfusion associated graft-versus-host disease, transfusion associated circulatory overload, and hypersensitivity transfusion reaction including anaphylaxis and transfusion-related immune-modulation. Many studies and guidelines have suggested RBCT is considered when hemoglobin levels recorded are 7 g/dL for general patients and 8-9 g/dL for patients with cardiovascular disease or hemodynamically unstable patients. However, RBCT is occasionally an essential treatment during surgeries and it is often required in emergency cases. We need to comprehensively consider postoperative bleeding, different clinical situations, the level of intra- and postoperative patient monitoring, and various problems that may arise from a transfusion, in the perspective of patient safety. Since orofacial surgery has an especially high risk of bleeding due to the complex structures involved and the extensive vascular distribution, measures to prevent bleeding should be taken and the conditions for a transfusion should be optimized and appropriate in order to promote patient safety.

Abstract
BACKGROUND Perioperative bleeding is a common side effect of rhinoplasty which may impose the blood transfusion to the patients. As a result of risks and cost of blood transfusion, this study is planned to reduce blood loss in these surgeries. Since tranexamic acid (TXA) has been reported to reduce bleeding and subsequent possible need for blood transfusion, the purpose of this study was to evaluate the efficacy of oral TXA on blood loss during rhinoplasty. METHODS AND MATERIALS In this double-blind, randomized, placebo-controlled clinical trial, 50 participants underwent rhinoplastic surgery. These participants were divided into 2 groups; 25 were randomly assigned to each 1. The patients in the first group received 1 g (2 × 500 mg) tranexamic acid tablets, and the patients in the second group received placebo 2 hours before starting the surgery. All patients were operated by the same surgical team and the same anesthetic techniques were used during the surgery. Gender, age, BMI, duration of operation, the amount of blood loss, and surgeon's satisfaction rate were the variables studied. RESULTS The first group (TXA group) consisted of 11 males (44%) and 14 females (56%) and the second group consisted of 13 males (52%) and 12 females (48%). There was no statistical difference in the distribution of the variables between the 2 groups, except for the blood loss, duration of operation, and surgeon's satisfaction. The mean total blood loss was 144.6 ± 60.28 mL in "group 1" and 199.6 ± 73.05 mL in "group 2" (P < 0.05). Duration of operation in the first group was less than the second group (2.60 ± 0.53 hours vs. 2.99 ± 0.59 hours) (P = 0.017). The surgeon was more satisfied with the quality of surgical field and visualization in "group 1" (3.76 ± 0.72) than "group 2" (2.16 ± 0.50) (P = 0.001). CONCLUSION The preoperative administration of 1 g oral tranexamic acid significantly decreased the blood loss in patients undergoing rhinoplastic surgery without any significant adverse effects.Iranian registry no:IRCT201312271674N10 (www.irct.ir).

Abstract
This retrospective study aimed to identify factors of importance for intraoperative blood loss relative to total blood volume in patients undergoing orthognathic surgery. The study included 356 patients treated consecutively at a Danish university hospital between 1 January 2010 and 31 December 2012. Inclusion criteria were (1) patient age ≥18 years and (2) patient undergoing a three-piece Le Fort I osteotomy, a bilateral sagittal split osteotomy, or a combination of the two. The patient-specific relative blood loss was calculated as a percentage by dividing the intraoperative blood loss by the estimated preoperative total blood volume, and then correlated with body mass index (BMI), age, sex, operating time, and treatment modality in a multivariate stepwise regression analysis. Operating time (P<0.001), BMI (P<0.001), and treatment modality (P<0.001) had a significant impact on relative blood loss; no significant effect of age or sex was observed. The coefficient of determination of relative blood loss was R(2)=0.34. In conclusion, this study introduces relative blood loss as a patient-specific measure of intraoperative blood loss. Average relative blood loss in this patient sample was 6.5%. Extensive surgery, a prolonged operating time, and reduced BMI significantly increase the intraoperative relative blood loss in patients undergoing orthognathic surgery.

Abstract
PURPOSE The objective of the study was to correlate different orthognathic surgical procedures with operating time and blood loss, reported from an accredited resident training institution. METHODS Ninety-five patient records were evaluated retrospectively. Individual blood volume, percent blood volume lost (BVL), and estimated blood loss (EBL) for each patient were recorded and correlated with operating time (OT). Statistics included independent t tests, one-way analysis of variance, and linear regression. RESULTS The mean OT for all procedures was 203 min with mean blood loss 556 ml. Mean EBL for males was 676 ml versus 468 ml for females. Overall BVL was 12.4 %, while for males, BVL was 13.3 % compared to 11.8 % for females. For a single orthognathic procedure (n = 45), mean OT 145 min., EBL 414 ml, and BVL 9.0 %; two procedures (n = 41), mean OT was 239 min., EBL 659 ml, and BVL 15 %; three procedures (n = 9), mean OT 328 min, EBL 793 ml, and BVL was 17 %. CONCLUSION Examination of individual procedures suggests a shorter OT for Le Fort I procedures with slightly greater EBL. Concomitant orthognathic procedures are associated with greater OT and EBL. Blood volume should be calculated for male and female patients separately. Percent BVL can be predicted based on OT using a basic equation.

Abstract
PURPOSE The purpose of the study was to evaluate changes of hematologic parameters in bimaxillary surgery. METHODS Fifty-three patients were prospectively evaluated and divided into groups based on the surgical procedure and sex (predictor variables). Hemoglobin, red blood cells, hematocrit, and platelet were the primary outcome variables, operation time the secondary outcome, and the patients' age and weight the other variables. TRIAL REGISTRATION NCT02364765 (U.S. National Institutes of Health, clinicaltrials.gov). RESULTS There was statistically significant difference between all hematologic parameters before and after surgery, for both men and women, and for all surgical groups. There was a positive correlation between operative time and the decrease (in %) of the hematologic parameters. Linear regression analysis suggested that the Hb values decrease 0.083 % for every minute increase in the operation time, and 0.066, 0.066, and 0.010 % for RBC, Hct, and platelet count, respectively. There was a negative correlation between weight and all hematologic parameters. Correlations between age and hematologic parameters were not statistically significant. Almost all correlations between age, weight, sex, and the surgery group and the hematologic parameters were considered as very weak. Only one patient was transfused. CONCLUSIONS It is suggested that operation time and patient's weight play a bigger role than patient's age and sex in the decrease of hematologic parameters after bimaxillary surgery.

Abstract
Objectives The purpose of this retrospective study was to compare the amount of postoperative drainage via closed suction drainage system after intraoral vertical ramus osteotomy (IVRO) and sagittal split ramus osteotomy (SSRO). Materials and Methods We planned a retrospective cohort study of 40 patients selected from a larger group who underwent orthognathic surgery from 2007 to 2013. Mean age (range) was 23.95 (16 to 35) years. Patients who underwent bilateral IVRO or SSRO were categorized into group I or group II, respectively, and each group consisted of 20 patients. Closed suction drainage system was inserted in mandibular osteotomy sites to decrease swelling and dead space, and records of drainage amount were collected. The data were compared and analyzed with independent t-test. Results The closed suction drainage system was removed at 32 hours postoperatively, and the amount of drainage was recorded every 8 hours. In group I, the mean amount of drainage was 79.42 mL in total, with 31.20 mL, 19.90 mL, 13.90 mL, 9.47 mL, and 4.95 mL measured at 0, 8, 16, 24, and 32 hours postoperatively, respectively. In group II, the mean total amount of drainage was 90.11 mL, with 30.25 mL, 25.75 mL, 19.70 mL, 8.50 mL, and 5.91 mL measured at 0, 8, 16, 24, and 32 hours postoperatively, respectively. Total amount of drainage from group I was less than group II, but there was no statistically significant difference between the two groups (P=0.338). There was a significant difference in drainage between group I and group II only at 16 hours postoperatively (P=0.029). Conclusion IVRO and SSRO have different osteotomy design and different extent of medullary exposure; however, our results reveal that there is no remarkable difference in postoperative drainage of blood and exudate.

Abstract
Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p < 0.05). Mean hematocrit values were 41.53 % preoperatively (range 31.3-50.0 %) and 36.56 % postoperatively (range 25-43.8 %) (p < 0.05). Mean blood loss was 274.60 mL (range 45-855 mL). Only two patients required blood transfusion. Although blood loss and transfusion requirements were minimal in the present study, surgical teams should monitor the duration of surgery and follow meticulous protocols to minimize the risks.

Abstract
PURPOSE Perioperative hemorrhage is an important concern during orthognathic surgery. The purpose of this study was to assess the effect of tranexamic acid (TXA) irrigation on perioperative hemorrhage during orthognathic surgery. MATERIALS AND METHODS In this double-blind, randomized controlled clinical trial, 56 participants who underwent orthognathic surgery were divided into 2 groups. The patients in the first group received TXA irrigation with normal saline (1 mg/mL), and the patients in the second group had normal saline for irrigation during orthognathic surgery. Age, gender, operation duration, the amount of irrigation solution used, and preoperative hemoglobin, hematocrit, and weight were the variables that were studied. The use of TXA solution for irrigation was the predictive factor of the study. RESULTS Each group consisted of 28 patients. Group 1 consisted of 15 male patients (53.6%) and 13 female patients (46.4%) and group 2 consisted of 14 male patients (50%) and 14 female patients (50%). There was no difference in the distributions of the variables between the 2 groups, except for the duration of the operation. The mean duration of the operation was 3.94 ± 0.61 hours in group 1 and 4.17 ± 0.98 hours in group 2, and the difference in this respect between the 2 groups was statistically significant (P < .05). The mean intraoperative blood loss was 817.85 ± 261.83 mL in group 1 and 575.00 ± 286.90 mL in group 2 (P < .05). The mean volume of irrigation was 1,057.14 ± 407.04 mL in group 1 and 843.57 ± 275.48 mL in group 2 (P > .05). CONCLUSIONS TXA is effective in reducing intraoperative blood loss in patients for whom substantial blood loss is anticipated.

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.

Abstract
The purpose of this prospective, randomized, double blind study was to assess the effect of tranexamic acid on blood loss, quality of surgical field and duration of surgery in adolescent orthognathic surgery patients. 50 consecutive patients, scheduled for orthognathic surgery were included. The study group (n=25) received tranexamic acid 10mg/kg as a bolus preoperatively followed by 1mg/kg as a maintenance dose intra operatively; the control group (n=25) received placebo (normal saline). All patients received moderate hypotensive anaesthesia with nitroglycerin and had surgery according to a standard protocol. Intra operative blood loss, duration of surgery, quality of surgical field, blood transfusion and complications, if any, were recorded. The mean total blood loss was 166.1±65.49ml in the study group and 256.4±77.80ml in the control group. The results showed statistically significant reduction in blood loss (p<0.001) and improved quality of surgical field (p<0.001) in the study group. There was no significant difference in duration of surgery and transfusion requirements between the two groups. In conclusion, preoperative and intra operative administration of the antifibrinolytic agent, tranexamic acid, is effective in controlling blood loss and improving the quality of the surgical field.

Abstract
PURPOSE To define factors that influence blood loss in bimaxillary osteotomies and the need for blood preparation at the Faculty of Dentistry, Mahidol University, Bangkok, Thailand. PATIENTS AND METHODS We retrospectively studied 208 patients who underwent bimaxillary osteotomies during 2005 to 2009. Possible factors for intraoperative blood loss such as age, body weight, gender, operative time, experience of the surgeons, and different operative procedures were statistically analyzed. RESULTS Female patients had a significantly higher percentage of blood loss from allowable blood loss than male patients (P = .006). Experience of the surgeons had a significant influence on blood loss (P = .02) and operative time (P < .001). No significant difference in blood loss was found among the 4 groups classified by operation (P = .852). Simple regression analysis showed a significantly positive correlation between blood loss and duration of operation (R(2) = 0.15, P < .001). There was no correlation between blood loss and patient age (P = .35). CONCLUSION The factors that influence blood loss include patient gender, experience of the surgeon, and operative time. Blood preparation should be considered in women, especially small individuals in whom a long operative time is expected and who are being operated on by an inexperienced surgeon. Because of the low rate of transfusion, a group-and-save policy is appropriate.

Abstract
Induced hypotensive anaesthesia and isovolaemic haemodilution are well-established blood-sparing techniques in major surgery. This prospective study compared them for blood loss, transfusion requirements, and surgical field quality during standardized orthognathic operations. In a surgeon-blinded trial, 60 healthy patients requiring either Le Fort I osteotomy or bimaxillary surgery were randomly allocated to receive normotensive anaesthesia, induced hypotensive anaesthesia, or induced hypotensive anaesthesia combined with isovolaemic haemodilution. Blood loss and haemoglobin level were measured intraoperatively and calculated on postoperative day 3. The surgeons rated surgical field quality. Mean blood loss was 1021.63, 392.38 (p<0.05) and 1191.65ml in the normotensive, hypotensive and haemodilution groups, respectively. Mean haemoglobin level immediately after surgery was 9.3, 10.3, and 7.4g/dl (p<0.05), respectively. No hypotensive group patients received transfusions; four normotensive group patients required allogenic transfusions; seven haemodilution group patients needed autogenous retransfusions (p<0.05). Surgical field quality was significantly better in the hypotensive than in the normotensive (p<0.05) or haemodilution (p<0.05) groups. In orthognathic surgery, hypotensive anaesthesia significantly reduces blood loss and transfusion requirements and minimizes allogenic transfusions risks. Induced hypotensive anaesthesia combined with isovolaemic haemodilution has no additional blood-sparing effects but impairs surgical field quality.
