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.

OBJECTIVE: To evaluate the early efficacy of local application of tranexamic acid on the osteotomy surface during hallux valgus surgery in reducing postoperative occult blood loss and thus postoperative swelling. METHODS: The data of 40 cases with hallux valgus osteotomy admitted to the Department of Foot and Ankle Surgery of Jishuitan Hospital from July 11, 2022 to October 8, 2022, including 5 males and 35 females were retrospectively analyzed. According to the inclusion and exclusion criteria, 32 cases were finally divided into 16 cases in the observation group (application of tranexamic acid) and 16 cases in the control group (no application of tranexamic acid). The observation group was paired with the control group one by one in accordance with the operation style, and the change in the anterior and posterior diameter of the first metatarsal head, the change in the circumferential diameter of the foot, the length of the first metatarsal midline and the length of the plumbline of the foot measured by postoperative CT were compared between the two groups before and after surgery, in order to evaluate the degree of swelling around the incision after the surgery. The first metatarsal midline and plumb line were measured by reference to the two auxiliary lines that intersect the soft tissue border in the sesamoid bone position to measure the rotation angle of the first metatarsal. A total of three clinicians completed the measurements of these two line segments and interobserver comparisons were performed. RESULTS: By interobserver comparison, the consistency of the length of the midline of the first metatarsal and the plumbline measured by CT was high and could be considered a reliable measurement. After the paired t-test, there was no statistical difference in the amount of changes in the anteroposterior diameter of the first metatarsal before and after surgery between the observation and control groups (P>0.05), and the amount of changes in the circumferential diameter of the foot before and after surgery was smaller in the observation group than in the control group, which was statistically significant (P < 0.05); the length of the midline of the first metatarsal and the plumbline of the foot measured by CT after surgery was smaller in the observation group than in the control group, which was statistically significant (P < 0.05). CONCLUSION Local application of tranexamic acid on the osteotomy surface during hallux valgus osteotomy can relieve postoperative swelling to some extent, which may be related to the fact that tranexamic acid reduces occult blood loss in the postoperative period.

INTRODUCTION: The use of periarticular (PA) tranexamic acid (TXA) and its efficacy in comparison with intra-articular (IA) TXA have not been well explored in the literature. This retrospective cohort study aimed to compare the effects of IA and PA TXA with analgesic components in reducing blood loss and improving immediate postoperative pain relief and functional outcomes in patients after unilateral primary total knee arthroplasty (TKA). METHODS: A total of 63 patients underwent TKA, and they were divided into the IA TXA delivery group ( n = 42) and PA TXA delivery group ( n = 21). All patients were administered 1 g of TXA. They also received pericapsular infiltration consisting of 0.5 mL of adrenaline, 0.4 mL of morphine, 1 g of vancomycin, 1 mL of ketorolac and 15 mL of ropivacaine. Outcomes for blood loss and surrogate markers for immediate functional recovery were measured. RESULTS: Of the 63 patients, 54% were female and 46% male. The mean drop in postoperative haemoglobin levels in the PA and IA groups was 2.0 g/dL and 1.6 g/dL, respectively, and this was not statistically significant ( P = 0.10). The mean haematocrit drop in the PA and IA groups was 6.1% and 5.3%, respectively, and this was also not statistically significant ( P = 0.58). The postoperative day (POD) 1 and discharge day flexion angles, POD 1 and POD 2 visual analogue scale (VAS) scores, gait distance on discharge and length of hospitalisation stay were largely similar in the two groups. CONCLUSION Our study showed that both IA and PA TXA with analgesic components were equally efficient in reducing blood loss and improving immediate postoperative pain relief and functional outcomes.

OBJECTIVE: To explore the effect of intravenous tranexamic acid on postoperative drainage and elbow joint function after traumatic elbow stiffness release. METHODS: The clinical data of 44 patients with elbow joint stiffness who were treated with release surgery between March 2022 and December 2023 and met the selection criteria were retrospectively analyzed. Among them, 20 patients were given intravenous infusion of 100 mL (1 g/100 mL, once a day) of tranexamic acid solution for 3 consecutive days after surgery (group A), and 24 patients were not treated with tranexamic acid after surgery (group B). There was no significant difference in baseline data such as gender, age, side, body mass index, initial injury, and preoperative hemoglobin, visual analogue scale (VAS) score, and Mayo elbow function score (MEPS), elbow flexion and extension activity between the two groups ( P>0.05). The drainage volume at 1 day and 3 days after operation, total drainage volume, drainage tube indwelling time, postoperative hospital stay, VAS score before operation and at 1, 2, and 3 days after operation, MEPS score before operation, at 3 months after operation, and at last follow-up, and elbow flexion and extension activity before operation and at last follow-up were recorded and compared between the two groups. RESULTS: Both groups of patients successfully completed the operation, and there was no significant difference in operation time ( P>0.05). The drainage volume at 1 day and 3 days after operation, total drainage volume, drainage tube indwelling time, and postoperative hospital stay in group A were significantly less than those in group B ( P<0.05). Both groups of patients were followed up 6-12 months, with an average of 8.6 months. No complications such as wound infection, elbow joint varus and varus instability or dislocation, and pulmonary embolism or other thromboembolic events occurred in either group. The VAS scores of both groups were significantly higher at 1 day and 2 days after operation than before operation ( P<0.05); the VAS score of group A was significantly lower than that of group B ( P<0.05). The VAS scores of both groups decreased to the preoperative level at 3 months after operation, and there was no significant difference between the two groups ( P>0.05). At 3 months after operation and at last follow-up, the MEPS scores of both groups significantly improved when compared with those before operation ( P<0.05); there was no significant difference between the two groups ( P>0.05). At last follow-up, the postoperative elbow flexion and extension activity of the two groups significantly increased when compared with that before operation ( P<0.05); there was no significant difference in change of elbow flexion and extension activity between the two groups ( P>0.05). CONCLUSION Intravenous tranexamic acid for 3 consecutive days after release of traumatic elbow stiffness can significantly reduce postoperative drainage volume, shorten drainage tube indwelling time and hospital stay, and relieve early postoperative pain, but it has no effect on the risk of thrombotic and embolic events and postoperative elbow function.

OBJECTIVE: To systematically evaluate the hemostatic efficacy of tranexamic acid and ε-aminocaproic acid in total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: Randomized controlled trials (RCT) and retrospective case-control studies about tranexamic acid and ε-aminocaproic acid for the comparison of THA or TKA were searched electronically in PubMed, EMbase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP from the time of building databases to July 2020. Two investigators carried out literature screening and data extraction according to the inclusion and exclusion criteria respectively. The methodological quality of the included randomized controlled studies was evaluated through the Cochrane Handbook, and the methodological quality of the included retrospective case-control studies was evaluated through the NOS scale. Blood loss, the incidence of thrombosis complications, per capita input of hemoglobin were Meta-analyzed by Review Manager 5.3 software. RESULTS: A total of 6 articles were included, including 4 RCTs and 2 retrospective case-control studies. A total of 3 174 patients, including 1 353 in the tranexamic acid group and 1 821 in the ε-aminocaproic acid group. Meta-analysis results showed that there were no difference statistical significance in blood loss [MD=-88.60, 95%CI(-260.30, 83.10), P=0.31], blood transfusion rate [OR=1.48, 95%CI(0.96, 2.27), P=0.08], thrombotic complications [OR=0.80, 95%CI(0.07, 8.83), P=0.85], per capita hemoglobin input [MD=0.04, 95%CI(-0.02, 0.10), P=0.18] between tranexamic acid group and ε-aminocaproic acid group during THA. While in TKA, the blood loss of the tranexamic acid group was less than that of the ε-aminocaproic acid group [MD=-147.13, 95%CI(-216.52, -77.74), P<0.0001], the difference was statistically significant. The blood transfusion rate [OR=1.30, 95%CI(0.74, 2.28), P=0.37], thrombotic complications [OR=0.95, 95%CI(0.38, 2.36), P=0.92], per capita hemoglobin input [MD=-0.00, 95%CI(-0.05, 0.06), P=0.48], tourniquet time [MD=1.54, 95%CI(-2.07, 5.14), P=0.40] were similar between two groups, the difference was not statistically significant. CONCLUSION In THA, tranexamic acid and ε-aminocaproic acid have similar hemostatic effects, while in TKA, tranexamic acid can effectively reduce the patient's blood loss and has a better hemostatic effect. Tranexamic acid is recommended as one of the first choice hemostatic drugs for TKA.

OBJECTIVE: To explore the effects of different administration methods of tranexamic acid(TXA) on the perioperative blood loss, hidden blood loss, transfusion rate and adverse reactions in lumbar spinal decompression and fusion. METHODS: Sixty patients who received lumbar spinal canal decompression and fusion from July 2019 to July 2020 were enrolled and divided into observation group and control group, with 30 cases in each group. The observation group was given 2 g TXA orally at 2 hours before operation, control group was given 1 g TXA for 5-10 min before skin incision and 6 hours after operation intravenously. The intraoperative blood loss, postoperative drainage, total blood loss, hidden blood loss, drainage tube removal time, blood transfusion rate, venous thrombosis rate, adverse event rate were recorded respectively. The changes of hemoglobin(Hb) and hematocrit (HCT) were observed before operation and 1, 3 days after operation. RESULTS: Hb and HCT at 1 and 3 days after operation were significantly improved compared with those before operation(P<0.01). However, there was no significant difference between the groups(P>0.05). There were no significant difference in amount of blood loss, postoperative drainage, total blood loss, intraoperative blood loss, hidden blood loss, postoperative drainage time, and blood transfusion rate between two groups (P>0.05). There were no venous thrombosis and adverse events occurred in both groups. CONCLUSION During the perioperative period of lumbar spinal decompression and fusion, oral TXA and intravenous TXA have the same effect in reducing perioperative blood loss and are safe and reliable. It is recommended that oral TXA be used to save medical costs and convenience.

OBJECTIVE: To investigate the application of tranexamic acid in the treatment of intertrochanteric fracture. METHODS: From January 2017 to October 2019, 100 patients with intertrochanteric fracture were randomly divided into observation group (48 cases) and control group(52 cases). All patients received the same surgical treatment. The control group was given tranexamic acid 20 minutes before operation, and 15 mg/kg diluted in 250 ml sodium chloride injection, intravenous drip;the observation group was given tranexamic acid 0.5 g dissolved in 20 ml normal saline injected into femoral bone marrow cavity for local treatment on the basis of the control group. The blood loss, operation time and postoperative hospital stay were compared between two groups. Hematocrit, hemoglobin, D-dimer and fibrinogen levels were analyzed before and after operation, and the incidence of thrombotic complications was observed. RESULTS: The total blood loss, dominant blood loss, hidden blood loss and postoperative drainage volume of the observation group were significantly lower than those of the control group ( CONCLUSION Tranexamic acid combined with systemic and local application has important clinical significance in reducing perioperative blood lossand blood cell loss in patients with intertrochanteric fracture, and has good safety.

OBJECTIVE: To evaluate the efficacy and safety of local application of tranexamic acid (TXA) in reducing perioperative blood loss in total hip arthroplasty via direct anterior approach (DAA). METHODS: From July 2013 to September 2018, 46 patients with avascular necrosis of the femoral head were divided into tranexamic acid group ( RESULTS: The incision healed well and no obvious complications occurred in the two groups. All patients were followed up for 12 to 59 months(averaged 31.11 months). No hip pain was found in the follow-up patients. Hip joint function was improved effectively and no prosthesis loosening occurred. The total perioperative blood loss in tranexamic acid group and normal saline group was(740.09±77.14) ml and (1 069.07±113.53) ml respectively, 24 hours after operation, the drainage volume was (87.61±9.28) ml, (233.83±25.62) ml, the hidden blood loss was (409.65±38.01) ml and (588.33±57.16) ml. the difference of hemoglobin before and after operation was (24.78±2.19) g / L and (33.57±2.95) g / L, the difference was statistically significant ( CONCLUSION local application of tranexamic acid in total hip arthroplasty through direct anterior approach can safely and effectively reduce perioperative blood loss, and does not increase the risk of thrombosis, and does not affect the normal recovery of joint function.
