Abstract
OBJECTIVE For elderly femoral neck fracture patients, anemia is one of the most common complications, increasing the risk of postoperative adverse events. Tranexamic acid (TXA) has been widely applied to the perioperative blood management. However, the optimal route of TXA administration in elderly femoral neck fracture remains unclear. The aim of this study is to evaluate the efficacy and safety of oral and intravenous (IV) application of TXA in elderly patients with femoral neck fracture undergoing total hip arthroplasty (THA) and hemiarthroplasty (HA). METHODS All elderly patients aged over 65 years old diagnosed with femoral neck fracture admitted to the trauma orthopedics from August 1, 2020 to February 28, 2022 were enrolled in this prospective cohort study. Participants were divided into three groups: oral group: TXA 2g orally 2 h before incision; IV group: intravenous infusion of TXA 1g 15 min before incision; and control group: usual hemostatic method. The primary outcomes were total blood loss, allogeneic transfusion rate, and postoperative thromboembolic events. SPSS 23.0 (IBM, Armonk, NY, USA) was used for statistical analysis, and p ≤ 0.05 was considered statistically significant. RESULTS A total of 100 patients were enrolled, including 32 cases in the oral group, 34 cases in the IV group and 34 cases in the control group. Compared with the control group, the total perioperative blood loss in the oral and IV groups was significantly decreased (763.92 ± 358.64 mL vs 744.62 ± 306.88 mL vs 1250.60 ± 563.37 mL, p = 0.048). No significant difference was identified between the oral and IV groups (p = 0.970). The rate of allogeneic transfusion was lower in the oral and IV groups than in the control group, but the difference had no statistical significant (6 vs 5 vs 12, p = 0.108), However, subgroup analysis showed that the IV and oral groups in patients who underwent THA have significant lower transfusion rate compared with the control group (1 vs 3 vs 7, p = 0.02). During 6 months follow-up, no thromboembolic events were identified. Two patients (one from the oral group and one from the control group) died of respiratory failure. The cost of blood management from the oral group was significantly lower than IV (p < 0.001) and control groups (p = 0.009). CONCLUSION Elderly patients with femoral neck fracture undergoing THA can benefit from both IV and oral administration of tranexamic acid. The results of these two administration routes are similar in safety and effectiveness. A similar tendency was observed in patients undergoing HA. Oral TXA is more cost-benefit compared with intravenous applications.

Efficacy and safety of tranexamic acid in elderly patients with femoral neck fracture treated with hip arthroplasty: A systematic review and meta-analysis. J Orthop Sci 2024; 29:542-551. [PMID: 36797125 DOI: 10.1016/j.jos.2023.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 01/14/2023] [Accepted: 01/16/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND Elderly patients with femoral neck fracture have high perioperative blood loss according to the trauma and hip arthroplasty surgery. Tranexamic acid is a fibrinolytic inhibitor and has been widely used in hip fracture patients to against perioperative anemia. The aim of the present meta-analysis was to evaluate the efficacy and safety of Tranexamic acid (TXA) in elderly patients with femoral neck fracture undergoing hip arthroplasty. METHODS We performed search using Pubmed, EMBASE, Cochrane Reviews, and Web of Science databases to identify all relevant research studies published from inception to June 2022. Randomized controlled studies and high-quality cohort studies that reported the perioperative use of TXA in patients with femoral neck fractures treated with arthroplasty, and made a comparison with the control group were included. Meta-analysis was performed using Review Manager 5.3 to assess the efficacy and safety of TXA. Subgroup analysis was conducted to further investigate the impact caused by surgery types and administration routes on the efficacy and safety outcomes. RESULTS Five randomized controlled trials (RCTs) and eight cohort studies published from January 2015 to June 2022 were included in this meta-analysis. The results showed significant reductions in the rate of allogeneic blood transfusion, total blood loss (TBL) and postoperative hemoglobin (Hb) drop in the TXA group compared with the control group, while no significant difference was found in the intraoperative blood loss, postoperative drainage, hospital length of stay (LOS), re-admission rate, and wound complications between the two groups. The incidence of thromboembolic events and mortality showed no significant difference. Subgroup analysis indicated that surgery types and administration routes did not change the overall tendency. CONCLUSION The current evidence shows that both intravascular administration (IV) and topical administration of TXA can significantly decrease the perioperative transfusion rate and TBL without increasing the risk of thromboembolic complications in elderly patients with femoral neck fracture.

Intramedullary administration of tranexamic acid reduces bleeding in proximal femoral nail antirotation surgery for intertrochanteric fractures in elderly individuals: A randomized controlled trial. Chin J Traumatol 2024:S1008-1275(24)00006-3. [PMID: 38429175 DOI: 10.1016/j.cjtee.2024.01.006] [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: 08/01/2023] [Revised: 12/15/2023] [Accepted: 01/02/2024] [Indexed: 03/03/2024] Open
Abstract
PURPOSE Intertrochanteric fractures undergoing proximal femoral nail antirotation (PFNA) surgery are associated with significant hidden blood loss. This study aimed to explore whether intramedullary administration of tranexamic acid (TXA) can reduce bleeding in PFNA surgery for intertrochanteric fractures in elderly individuals. METHODS A randomized controlled trial was conducted from January 2019 to December 2022. Patients aged over 60 years with intertrochanteric fractures who underwent intramedullary fixation surgery with PFNA were eligible for inclusion and grouped according to random numbers. A total of 249 patients were initially enrolled, of which 83 were randomly allocated to the TXA group and 82 were allocated to the saline group. The TXA group received intramedullary perfusion of TXA after the bone marrow was reamed. The primary outcomes were total peri-operative blood loss and post-operative transfusion rate. The occurrence of adverse events was also recorded. Continuous data was analyzed by unpaired t-test or Mann-Whitney U test, and categorical data was analyzed by Pearson Chi-square test. RESULTS The total peri-operative blood loss (mL) in the TXA group was significantly lower than that in the saline group (577.23 ± 358.02 vs. 716.89 ± 420.30, p = 0.031). The post-operative transfusion rate was 30.67 % in the TXA group and 47.95 % in the saline group (p = 0.031). The extent of post-operative deep venous thrombosis and the 3-month mortality rate were similar between the 2 groups. CONCLUSION We observed that intramedullary administration of TXA in PFNA surgery for intertrochanteric fractures in elderly individuals resulted in less peri-operative blood loss and decreased transfusion rate, without any adverse effects, and is, thus, recommended.

Lewis SR, Pritchard MW, Estcourt LJ, Stanworth SJ, Griffin XL. Interventions for reducing red blood cell transfusion in adults undergoing hip fracture surgery: an overview of systematic reviews. Cochrane Database Syst Rev 2023; 6:CD013737. [PMID: 37294864 PMCID: PMC10249061 DOI: 10.1002/14651858.cd013737.pub2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
BACKGROUND Following hip fracture, people sustain an acute blood loss caused by the injury and subsequent surgery. Because the majority of hip fractures occur in older adults, blood loss may be compounded by pre-existing anaemia. Allogenic blood transfusions (ABT) may be given before, during, and after surgery to correct chronic anaemia or acute blood loss. However, there is uncertainty about the benefit-risk ratio for ABT. This is a potentially scarce resource, with availability of blood products sometimes uncertain. Other strategies from Patient Blood Management may prevent or minimise blood loss and avoid administration of ABT. OBJECTIVES To summarise the evidence from Cochrane Reviews and other systematic reviews of randomised or quasi-randomised trials evaluating the effects of pharmacological and non-pharmacological interventions, administered perioperatively, on reducing blood loss, anaemia, and the need for ABT in adults undergoing hip fracture surgery. METHODS In January 2022, we searched the Cochrane Library, MEDLINE, Embase, and five other databases for systematic reviews of randomised controlled trials (RCTs) of interventions given to prevent or minimise blood loss, treat the effects of anaemia, and reduce the need for ABT, in adults undergoing hip fracture surgery. We searched for pharmacological interventions (fibrinogen, factor VIIa and factor XIII, desmopressin, antifibrinolytics, fibrin and non-fibrin sealants and glue, agents to reverse the effects of anticoagulants, erythropoiesis agents, iron, vitamin B12, and folate replacement therapy) and non-pharmacological interventions (surgical approaches to reduce or manage blood loss, intraoperative cell salvage and autologous blood transfusion, temperature management, and oxygen therapy). We used Cochrane methodology, and assessed the methodological quality of included reviews using AMSTAR 2. We assessed the degree of overlap of RCTs between reviews. Because overlap was very high, we used a hierarchical approach to select reviews from which to report data; we compared the findings of selected reviews with findings from the other reviews. Outcomes were: number of people requiring ABT, volume of transfused blood (measured as units of packed red blood cells (PRC)), postoperative delirium, adverse events, activities of daily living (ADL), health-related quality of life (HRQoL), and mortality. MAIN RESULTS We found 26 systematic reviews including 36 RCTs (3923 participants), which only evaluated tranexamic acid and iron. We found no reviews of other pharmacological interventions or any non-pharmacological interventions. Tranexamic acid (17 reviews, 29 eligible RCTs) We selected reviews with the most recent search date, and which included data for the most outcomes. The methodological quality of these reviews was low. However, the findings were largely consistent across reviews. One review included 24 RCTs, with participants who had internal fixation or arthroplasty for different types of hip fracture. Tranexamic acid was given intravenously or topically during the perioperative period. In this review, based on a control group risk of 451 people per 1000, 194 fewer people per 1000 probably require ABT after receiving tranexamic acid (risk ratio (RR) 0.56, 95% confidence interval (CI) 0.46 to 0.68; 21 studies, 2148 participants; moderate-certainty evidence). We downgraded the certainty for possible publication bias. Review authors found that there was probably little or no difference in the risks of adverse events, reported as deep vein thrombosis (RR 1.16, 95% CI 0.74 to 1.81; 22 studies), pulmonary embolism (RR 1.01, 95% CI 0.36 to 2.86; 9 studies), myocardial infarction (RR 1.00, 95% CI 0.23 to 4.33; 8 studies), cerebrovascular accident (RR 1.45, 95% CI 0.56 to 3.70; 8 studies), or death (RR 1.01, 95% CI 0.70 to 1.46; 10 studies). We judged evidence from these outcomes to be moderate certainty, downgraded for imprecision. Another review, with a similarly broad inclusion criteria, included 10 studies, and found that tranexamic acid probably reduces the volume of transfused PRC (0.53 fewer units, 95% CI 0.27 to 0.80; 7 studies, 813 participants; moderate-certainty evidence). We downgraded the certainty because of unexplained high levels of statistical heterogeneity. No reviews reported outcomes of postoperative delirium, ADL, or HRQoL. Iron (9 reviews, 7 eligible RCTs) Whilst all reviews included studies in hip fracture populations, most also included other surgical populations. The most current, direct evidence was reported in two RCTs, with 403 participants with hip fracture; iron was given intravenously, starting preoperatively. This review did not include evidence for iron with erythropoietin. The methodological quality of this review was low. In this review, there was low-certainty evidence from two studies (403 participants) that there may be little or no difference according to whether intravenous iron was given in: the number of people who required ABT (RR 0.90, 95% CI 0.73 to 1.11), the volume of transfused blood (MD -0.07 units of PRC, 95% CI -0.31 to 0.17), infection (RR 0.99, 95% CI 0.55 to 1.80), or mortality within 30 days (RR 1.06, 95% CI 0.53 to 2.13). There may be little or no difference in delirium (25 events in the iron group compared to 26 events in control group; 1 study, 303 participants; low-certainty evidence). We are very unsure whether there was any difference in HRQoL, since it was reported without an effect estimate. The findings were largely consistent across reviews. We downgraded the evidence for imprecision, because studies included few participants, and the wide CIs indicated possible benefit and harm. No reviews reported outcomes of cognitive dysfunction, ADL, or HRQoL. AUTHORS' CONCLUSIONS Tranexamic acid probably reduces the need for ABT in adults undergoing hip fracture surgery, and there is probably little or no difference in adverse events. For iron, there may be little or no difference in overall clinical effects, but this finding is limited by evidence from only a few small studies. Reviews of these treatments did not adequately include patient-reported outcome measures (PROMS), and evidence for their effectiveness remains incomplete. We were unable to effectively explore the impact of timing and route of administration between reviews. A lack of systematic reviews for other types of pharmacological or any non-pharmacological interventions to reduce the need for ABT indicates a need for further evidence syntheses to explore this. Methodologically sound evidence syntheses should include PROMS within four months of surgery.
