Journal of clinical medicine. 2022;11(23)
Abstract
BACKGROUND Visual clarity during shoulder arthroscopy can ensure an efficient and effective performance of the procedure, and it is highly related to bleeding without a tourniquet. Tranexamic acid (TXA) is widely used in adult reconstruction procedures; however, its use in shoulder arthroscopic operations is a relatively novel topic. PURPOSE To analyze the available literature on visual clarity, blood loss, pain control, functional outcomes, and complications after the administration of tranexamic acid in shoulder arthroscopic surgery. METHODS A literature search was performed to retrieve randomized controlled trials examining the use of tranexamic acid at the time of shoulder arthroscopic surgery. The literature search included the MEDLINE, Embase, Web of Science, and Cochrane Library databases. The primary outcomes included visual clarity, blood loss, and visual analog scale scores for pain. Secondary outcomes were operative time, irrigation amount used, postoperative shoulder swelling, the need for pressure increase, mean arterial pressure (MAP), functional outcomes, postoperative adverse effects such as deep venous thrombosis, and pulmonary embolism. The outcomes were pooled to perform a meta-analysis. RESULTS Seven prospective randomized controlled trials met the inclusion criteria for analysis. All of the included studies performed arthroscopic rotator cuff repair. No significant difference in visual clarity was observed (SMD (standardized mean difference), 0.45 [95% CI(confidence interval), -0.68, 1.59]; p = 0.44) nor in pain score (MD (mean difference), -0.46 [95% CI, -0.97, 0.05]; p = 0.08) between the TXA group and the control group. Two studies found no significant difference in blood loss between the TXA group and the control group. The meta-analysis from five studies demonstrated no significant difference between the TXA and control groups in operative time (MD, -3.51 [95% CI, -15.82, 8.80]; p = 0.58) or irrigation amount used (MD, -2.53 [95% CI, -5.93, 0.87]; p = 0.14). Two trials reported different statistical results in postoperative shoulder swelling. No significant differences regarding the need for pressure increase and MAP were reported between groups. No wound complications or infections or cardiac, thrombotic, or thromboembolic complications were recorded in either group. CONCLUSION The use of intravenous or local TXA in shoulder arthroscopic surgery did not increase complications or thromboembolic events, but TXA had no obviously effect of reducing bleeding to obtain a clear visual field or pain release in patients undergoing shoulder arthroscopic surgery.

Abstract
OBJECTIVE To evaluate the efficacy and safety of topical glucocorticoids for total hip arthroplasty by meta-analysis. METHODS A computerized search of the Cochrane Library, MEDLINE, EMBASE, and PubMed English databases, as well as Chinese Biomedical Literature Database, vipu Chinese Science and Technology Journal Database, Wanfang database, and Chinese Knowledge Net Database, was performed to include all randomized controlled trials (RCTs) regarding topical glucocorticoid therapy for postoperative bleeding after THA according to the inclusion criteria. The quality evaluation criteria of RCTs, as stated in the Cochrane Handbook for Systematic Reviews of Interventions 4.2.5, were adopted for evaluation, and the meta-analysis was performed using RevMan 5.3. RESULTS A total of 10 articles were included, including 1,112 patients: 566 in the topical glucocorticoid group and 546 in the control group. The transfusion rate was 8.43% for topical glucocorticoids and 30.05% for the control group (P < 0.001), and topical glucocorticoids reduced 317.89 ml total blood loss and 76.82 ml invisible blood loss, with statistically significant differences (P < 0.001). The amount of intraoperative blood loss was reduced by topical glucocorticoids, but the difference was not statistically significant (P=0.83), and the postoperative HB value was increased by topical glucocorticoids, although the difference was statistically significant (P < 0.001). The incidence of DVT and PE after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%), the difference was not statistically significant (P=0.54), and the incidence of infection after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%). The difference was not statistically significant (P=0.39). CONCLUSIONS Topical glucocorticoids can reduce the transfusion rate and blood loss in THA patients without increasing their risk of thrombosis.

Annals of medicine. 2021;53(1):1816-1826
Abstract
OBJECTIVE Total knee replacement (TKA) is an effective way to treat teratogenic and disabling knee diseases such as advanced osteoarthritis. Tourniquets are often used in TKA to reduce bleeding and to get a better visualization of the surgical field, while it is related to safety concerns. We did this network meta-analysis to comprehensively compare the efficacy and safety of various tourniquet application strategies. METHOD PubMed, Embase, Cochrane Library, CNKI, and WanFang Database were systematically searched from January 1990 to May 2020. A network meta-analysis with a frequentist framework was done to assess the relative efficacy and safety by comparing seven clinical important endpoints. RESULTS 38 eligible studies that assessed 3007 participants who underwent TKA were included in this network meta-analysis. Tourniquet inflation before osteotomy then deflation after wound closure effectively reduce perioperative bleeding (WMD compared with control group -234.66, 95% CI [-409.19 to -60.13]), while shortening the operation time (WMD -8.98, 95%CI [-14.07 to -3.88]) and reducing postoperative complications, including DVT (OR -0.58, 95%CI [-1.19 to 0.03]) and minor wound complications (OR -1.38, 95%CI [-3.00 to 0.25]). No difference was found in the late postoperative knee pain and function outcomes. CONCLUSIONS Using tourniquets during the entire operation can effectively reduce blood loss, but it also can cause many safety problems, including DVTs, wound oozing, delayed healing, and serious wound complications. Tourniquet inflation before osteotomy then deflation after wound closure effectively can reduce perioperative bleeding while shortening the operation time and reducing postoperative complications, so it could be the ideal tourniquet application strategy in TKA.Key messagesThis is the first study that comprehensively compared different tourniquet application strategies to evaluate their impact on postoperative recovery following TKA, and five clinically important endpoints were assessed in this study: perioperative blood loss, operation time, postoperative pain and function, and complications.We conclude that tourniquet inflation before osteotomy then deflation after wound closure could be the ideal tourniquet application strategy in TKA.

Chen Z, Ma Y, Li Q, Deng Z, Zheng Q
Annals of palliative medicine. 2020
Abstract
BACKGROUND As Asian populations, Chinese have a lower rate of high-risk gene mutations in venous thrombosis. Therefore, individual patient risk assessment, rather than a "blanket policy", is considered the best thromboembolism prophylaxis for Chinese. The purpose of this study was to evaluate the effectiveness and safety of selective thromboembolism prophylaxis compared with conventional thromboembolism prophylaxis by risk stratification with thromboelastography (TEG) after joint arthroplasty in Chinese. METHODS Between August 2016 to August 2017, Chinese patients who underwent hip or knee arthroplasty were randomly divided into a selective anticoagulation group (SAG) and a conventional anticoagulation group (CAG). Participants and outcome assessors were blinded. In the SAG, an anticoagulant was used when TEG indicated hypercoagulability; while in the CAG, an anticoagulant was regularly used until one month after surgery. Outcome evaluation included effectiveness (defined as the incidence of VTE), and safety (defined as the incidence of bleeding events, poor wound healing, blood loss, and infection). RESULTS A total of 197 patients (79 in the SAG and 118 in the CAG) were included in the study. There was 1 case of deep vein thrombosis (DVT) in the SAG and 2 cases of DVT in the CAG, but there was no significant difference between the two groups. Hidden blood loss in the SAG was 707.4±539.8 mL and hidden blood loss in the CAG was 617±565.0 mL, respectively (P>0.05). No significant difference was observed in perioperative blood loss between the SAG and the CAG (1,024.9±597.9 and 1,139.3±620.9 mL, respectively). Volume of blood transfusion was 92.4±270.2 mL in the SAG and 224.6±416.3 mL in the CAG, respectively, while rate of transfusion was 13.9% in the SAG and 33.9% in the CAG, respectively, which were significantly different between the two groups (P<0.05). CONCLUSIONS In Chinese patients who underwent hip or knee arthroplasty, the efficacy of selective anticoagulation using TEG in risk stratification was comparable to that of conventional anticoagulation. Furthermore, the safety of selective anticoagulant prophylaxis was superior to that of conventional anticoagulant prophylaxis.

Medicine. 2020;99(2):e18577
Abstract
BACKGROUND Autologous blood transfusion helps to avoid or reduce the need for allogenic blood transfusion in patients undergoing major surgery. We examined the value of erythropoietin therapy to support preoperative autologous blood donation (PABD) in patients undergoing orthopedic surgery. METHODS For this systematic review and meta-analysis, Medline, Cochrane, EMBASE, and Google Scholar databases were searched from October 26th, 1989 until September 30th, 2017. Primary outcomes were percentages of patients able to donate ≥4 units of blood for autologous transfusion, amount of allogeneic blood transfused, changes in hematocrit and hemoglobin levels from before PABD to immediately before surgery, and adverse events. RESULTS Of 256 studies identified, 18 studies met the inclusion criteria with a total of 1914 patients (mean age 51-69 years), of whom 1153 were treated with erythropoietin. Erythropoietin was associated with a greater percentage of patients able to donate ≥4 units of blood for autologous use compared to controls (OR = 6.00, 95% CI = 3.97 to 9.09, P < .001). Patients receiving preoperative erythropoietin had significantly less of a reduction in hematocrit and hemoglobin levels from before PABD to immediately before surgery compared with controls (hematocrit: mean differences = -1.438, 95% CI = -2.14 to -0.73, P < .001; hemoglobin: mean differences = -1.426, 95% CI = -1.78 to -1.07, P < .001). No significant differences were observed in the amount of allogenic blood transfused between patients receiving erythropoietin and controls (difference in means = -0.220, 95% CI = -0.536 to 0.097, P = .174). Patients who received erythropoietin were less likely to experience dizziness than controls, but the incidence of nausea or fatigue were similar between groups. CONCLUSION Erythropoietin therapy during the PABD period results in less of a reduction in hematocrit and hemoglobin levels and an increase in the percentage of patients able to donate blood preoperatively.

Wang D, Yang Y, He C, Luo ZY, Pei FX, Li Q, Zhou ZK, Zeng WN
Thrombosis and haemostasis. 2019;119(1):92-103
Abstract
Tranexamic acid (TXA) reduces surgical blood loss and alleviates inflammatory response in total hip arthroplasty. However, studies have not identified an optimal regimen. The objective of this study was to identify the most effective regimen of multiple-dose oral TXA in achieving maximum reduction of blood loss and inflammatory response based on pharmacokinetic recommendations. We prospectively studied four multiple-dose regimens (60 patients each) with control group (group A: matching placebo). The four multiple-dose regimens included: 2-g oral TXA 2 hours pre-operatively followed by 1-g oral TXA 3 hours post-operatively (group B), 2-g oral TXA followed by 1-g oral TXA 3 and 7 hours post-operatively (group C), 2-g oral TXA followed by 1-g oral TXA 3, 7 and 11 hours post-operatively (group D) and 2-g oral TXA followed by 1-g oral TXA 3, 7, 11 and 15 hours post-operatively (group E). The primary endpoint was estimated blood loss on post-operative day (POD) 3. Secondary endpoints were thromboelastographic parameters, inflammatory components, function recovery and adverse events. Groups D and E had significantly less blood loss on POD 3, with no significant difference between the two groups. Group E had the most prolonged haemostatic effect, and all thromboelastographic parameters remained within normal ranges. Group E had the lowest levels of inflammatory cytokines and the greatest range of motion. No thromboembolic complications were observed. The post-operative four-dose regimen brings about maximum efficacy in reducing blood loss, alleviating inflammatory response and improving analgaesia and immediate recovery.

Efficacy and Safety of Tranexamic Acid for Controlling Bleeding During Surgical Treatment of Intertrochanteric Fragility Fracture with Proximal Femoral Nail Anti-rotation: A Randomized Controlled Trial
Luo X, He S, Lin Z, Li Z, Huang C, Li Q
Indian journal of orthopaedics. 2019;53(2):263-269
Abstract
Background: Intertrochanteric fragility fracture (IFF) treated with proximal femoral nail anti-rotation (PFNA) is associated with significant hidden blood loss and high blood transfusion rate. The purpose of the present study was to evaluate the efficacy and safety of tranexamic acid (TXA) in reducing blood loss in these patients. Materials and Methods: Consecutive eligible patients were recruited and randomly assigned to a TXA group or a control group. The TXA group received 15 mg/kg body weight of TXA intravenously 15 min before incision and the same dose 3 h later. The control group received 100 mL of saline intravenously 15 min before incision. The efficacy outcomes included the total perioperative blood loss, postoperative transfusion rate, postoperative hemoglobin level, and length of the hospital stay. The safety outcomes were the incidence of thrombotic events and the mortality rate within 6 weeks after surgery. Results: We had 44 patients in the TXA group and 46 patients in the control group for the final analysis. The TXA group had significantly lower total perioperative blood loss than the control group (384.5 +/- 366.3 mL vs. 566.2 +/- 361.5 mL; P < 0.020). Postoperative transfusion rate was 15.9% in the TXA group versus 36.9% in the control group (P = 0.024). Each group had one patient with postoperative deep venous thrombosis. In the control group, three patients had cerebral infarction, and one patient died within 6 weeks after the operation. Conclusion: Intravenous TXA is effective in reducing total perioperative blood loss and transfusion rate in IFF treated with PFNA. No increased risk of thrombotic events was observed with the use of TXA; however, this study was underpowered for detecting this outcome. Further research is necessary before TXA can be recommended for high-risk patients.

Wang D, Wang HY, Luo ZY, Meng WK, Pei FX, Li Q, Zhou ZK, Zeng WN
Bone & Joint Journal. 2018;100 B.C.((8)):1025-1032.
Abstract
Aims The aim of this study was to identify the most effective regimen of multiple doses of oral tranexamic acid (TXA) in achieving maximum reduction of blood loss in total knee arthroplasty (TKA). Patients and Methods In this randomized controlled trial, 200 patients were randomized to receive a single dose of 2.0 g of TXA orally two hours preoperatively (group A), a single dose of TXA followed by 1.0 g orally three hours postoperatively (group B), a single dose of TXA followed by 1.0 g three and nine hours postoperatively (group C), or a single dose of TXA followed by 1.0 g orally three, nine, and 15 hours postoperatively (group D). All patients followed a routine enhanced-recovery protocol. The primary outcome measure was the total blood loss. Secondary outcome measures were hidden blood loss (HBL), reduction in the level of haemoglobin, the rate of transfusion and adverse events. Results Groups C (661.1 ml, sd 262.4) and D (597.7 ml, sd 219.6) had significantly lower mean total blood loss compared with groups A and B. The mean HBL was significantly lower in groups B (699.2 ml), C (533.1 ml) and D (469.9 ml) than in group A (p = 0.006, p < 0.001, and p < 0.001, respectively). Groups C (2.22 ml, sd 0.91) and D (2.04 ml, sd 0.95) had a lower reduction in the level of haemoglobin than groups A and B. However, there were no differences between groups C and D in relation to the three parameters. Conclusion The addition of two or three postoperative doses of TXA to one preoperative dose produced a significant reduction in blood loss. The two-dose postoperative regimen is the least necessary regimen for clinical efficacy in primary unilateral TKA. The three-dose regimen produced maximum reduction of blood loss.

Comparison of oral versus intra-articular tranexamic acid in enhanced-recovery primary total knee arthroplasty without tourniquet application: a randomized controlled trial
Wang D, Zhu H, Meng W K, Wang H Y, Luo Z Y, Pei F X, Li Q, Zhou Z K
Bmc Musculoskeletal Disorders. 2018;19((1)):85.
Abstract
BACKGROUND Although randomized controlled trials have confirmed oral tranexamic acid (TXA) can provide similar blood-sparing efficacy compared with intravenous (IV) TXA in total knee arthroplasty (TKA), some concerns do remain about thromboembolic events after such systemic administration. Many studies have confirmed that intra-articular (IA) application of TXA can show similar blood-saving efficacy with minimal levels of systemic absorption compared with IV TXA. However, it remains unclear whether the efficacy and safety of oral TXA administration is equal to or less than that of IA administration in TKA without the use of a tourniquet and drain. Thus, this study was to verify non-inferior efficacy and safety of oral TXA compared with IA TXA in primary TKA. METHODS A double-blind, randomized, controlled trial was performed to compare three oral doses of TXA (2 g of TXA 2 h before incision, and 1 g of TXA 6 and 12 h after surgery, respectively) with IA TXA (3 g of TXA in 100 mL of saline solution). One hundred forty-seven patients scheduled for TKA were randomized to one of the two interventions. The primary outcome was total blood loss. The secondary outcomes included reduction of hemoglobin concentration, clinical outcomes, blood coagulation values, thromboembolic complications, and transfusion rates. RESULTS The mean total blood loss was 788.8 mL in the oral TXA group compared with 872.4 mL in the IA TXA group, with no statistical significance (p > 0.05). There were no significant differences in reduction of hemoglobin level, blood coagulation level, and clinical outcomes. The transfusion rates were 4% in oral group and 5% IA group, respectively. Also, no significant differences were identified in thromboembolic complications. CONCLUSION Oral TXA according to the described protocol demonstrated non-inferiority for primary TKA, with no safety concerns and a greatly reduced cost, compared with the IA TXA. This randomized controlled trial supports the oral administration of TXA in TKA. TRIAL REGISTRATION The trial was registered in the Chinese Clinical Trial Registry ( ChiCTR-INR-17010968 ) dated 23rd March 2017.

Abstract
BACKGROUND The objective of this meta-analysis was to evaluate the efficacy and safety of tranexamic acid (TXA) in shoulder arthroplasty (SA). METHODS Academic articles were identified from the Cochrane Library, Medline (1966-2017.2), PubMed (1966-2017.2), Embase (1980-2017.2), and ScienceDirect (1966-2017.2). Randomized controlled trials (RCTs) and non-RCTs studying TXA in SA were included. Two independent reviewers conducted independent data abstraction. The I statistic was used to assess heterogeneity. Fixed- or random-effects models were used for meta-analysis. RESULTS Two RCTs and 2 non-RCTs met the inclusion criteria. This meta-analysis found significant differences in postoperative hemoglobin reduction (MD = -0.71 g/dL), drainage volume (MD = -133.21 mL), and total blood loss (MD = -226.82 mL) between TXA groups and controls. There were no significant differences in blood transfusion requirements, operation time, or length of hospital stay. CONCLUSIONS The use of TXA in SA decreases postoperative hemoglobin reduction, drainage volume, and total blood loss and does not increase the risk of complications. Because of the limited high-quality evidence currently available, additional randomized controlled trials are required.
