Comparison of therapeutic effects between drainage blood reinfusion and temporary clamping drainage after total knee arthroplasty in patients with rheumatoid arthritis

Comparative study of carbazochrome sodium sulfonate and tranexamic acid in reducing blood loss and inflammatory response following direct anterior total hip arthroplasty: a prospective randomized controlled trial

PURPOSE

Carbazochrome sodium sulfonate (CSS) is a haemostatic agent. However, its hemostatic and anti-inflammatory effects in patients undergoing total hip arthroplasty (THA) via a direct anterior approach (DAA) are unknown. We investigated the efficacy and safety of CSS combined with tranexamic acid (TXA) in THA using DAA.

METHODS

This study enrolled 100 patients who underwent primary, unilateral THA through a direct anterior approach. Patients were randomly divided into two groups: Group A used a combination of TXA and CSS, while Group B used TXA only. The primary outcome was total perioperative blood loss. The secondary outcomes were hidden blood loss, postoperative blood transfusion rate, inflammatory reactant levels, hip function, pain score, venous thromboembolism (VTE), and incidence of associated adverse reactions.

RESULTS

The total blood loss (TBL) in group A was significantly lower than in group B. The levels of inflammatory reactants and the rate of blood transfusion were also significantly lower. However, the two groups had no significant differences in intraoperative blood loss, postoperative pain score, or joint function. There were no significant differences in VTE or postoperative complications between the groups.

CONCLUSION

As a haemostatic agent, CSS combined with TXA can reduce postoperative blood loss in patients undergoing THA via DAA and seems to have an anti-inflammatory effect. Moreover, it did not increase the incidence of VTE or its related complications.

The efficacy and safety of tranexamic acid in rheumatoid arthritis patients undergoing simultaneous bilateral total knee arthroplasty: a multicenter retrospective study

BACKGROUND

The efficacy and safety of tranexamic acid (TXA) in reducing blood loss following total knee arthroplasty (TKA) in patients with osteoarthritis have been widely confirmed. However, there is still a paucity of the evidences regarding the effectiveness of TXA in patients with rheumatoid arthritis (RA). The purpose of the study is to explore the efficacy and safety of intravenous TXA on blood loss and transfusion risk following simultaneous bilateral TKA (SBTKA) in patients with RA.

METHODS

As a multicenter retrospective study, a total of 74 patients diagnosed with RA who underwent SBTKA were assigned into TXA group (15 mg/kg intravenous TXA before skin incision, n = 50) and control group (no TXA use, n = 24). The primary outcomes were total blood loss (TBL) and intraoperative blood loss (IBL). The secondary outcomes were hemoglobin (Hb) and hematocrit (Hct) drop on postoperative day 3, transfusion rate and volume, ambulation time, length of stay, hospitalization expenses and the incidence of complications.

RESULTS

The mean TBL, IBL and transfusion volume in TXA group were significantly lower than those in control group. The Hb and Hct drop on postoperative day 3 in control group were higher than those in TXA group (p<0.05). The similar trend was detected on transfusion rate, ambulation time and length of stay. The incidence of complications and hospitalization expenses did not differ significantly between the two groups (p>0.05).

CONCLUSIONS

TXA could effectively reduce blood loss, decrease transfusion risk, shorten ambulation time and length of stay following SBTKA in patients with RA, without increasing the risk of complications.

Is there a role of tranexamic acid in rheumatoid arthritis with total knee arthroplasty? Findings from a multicenter prospective cohort study in China

BACKGROUND

Tranexamic acid (TXA) has proven to be effective in reducing the blood loss associated with total knee arthroplasty (TKA) in patients with osteoarthritis. However, there still exists a paucity of evidence regarding the effectiveness of intravenous TXA in patients with rheumatoid arthritis. The aim of this study was to explore the efficacy and safety of intravenous TXA on blood loss after TKA in Chinese patients with rheumatoid arthritis.

MATERIALS AND METHODS

A total of 405 patients with rheumatoid arthritis who had undergone TKA were categorized into two groups based on the protocol of TXA use. TXA group (n = 248): patients received 15 mg/kg TXA prior to operation. Control group (n = 157): patients received no TXA. The outcome measurements such as, total blood loss (TBL), intraoperative blood loss (IBL), hidden blood loss (HBL), transfusion, drainage, the timing of first ambulation, the length of stay (LOS), total hospitalization costs, the results of 12-Item Short Form Survey (SF-12), the incidence of thromboembolic events and other complications were recorded and compared.

RESULTS

The mean TBL, IBL, HBL, volume of transfusion and drainage were significantly lower in TXA group than in Control group. The rate of transfusion was significantly lower in TXA group than in Control group. There was a favorable effect in early ambulation for patients in TXA group, compared with patients in Control group. In addition, TXA group had shorter LOS, lower hospitalization costs and higher postoperative SF-12 score than Control group. The incidence of deep venous thrombosis and other complications did not differ between the two groups.

CONCLUSION

TXA can effectively diminish blood loss, reduce transfusion, shorten LOS and decrease hospitalization costs after TKA in Chinese patients with rheumatoid arthritis, without increasing the risk of complications.

Effectiveness of preemptive antifibrinolysis with tranexamic acid in rheumatoid arthritis patients undergoing total knee arthroplasty: a study protocol for a randomized controlled trial

BACKGROUND

Patients with rheumatoid arthritis (RA) who have undergone total knee arthroplasty are at increased risk of requiring a blood transfusion. This study is designed to compare the effects of preemptive antifibrinolysis of single-dose and repeat-dose tranexamic acid (TXA) in in RA patients undergoing total knee arthroplasty (TKA).

METHODS/DESIGN

The study will be a double-blind randomized controlled trial with two parallel groups of RA patients. Group A will be given 100 ml normal saline twice daily starting from 3 days before the operation, Group B will be given TXA 1.5 g twice daily starting from 3 days before the operation. All patients will be given TXA 1.5 g 30 min before the operation. The primary outcomes will be evaluated with total blood loss and hidden blood loss. Other outcome measurements such as, fibrinolysis parameters, inflammatory factors, visual analogue scale for post-operative pain, analgesia usage, coagulation parameters, transfusion, the length of stay (LOS), total hospitalization costs, the incidence of thromboembolic events and other complications will be recorded and compared. Recruitment is scheduled to begin on 1 August 2020, and the study will continue until 31 May 2021.

DISCUSSION

In current literature there is a lack of evidence with regard to the efficacy of TXA in RA patients. The findings of this study, whether positive or negative, will contribute to the formulation of further recommendations on the use of TXA in RA patients undergoing TKA.

Tranexamic acid plus drain-clamping can reduce blood loss in total knee arthroplasty: A systematic review and meta-analysis

BACKGROUND

The efficacy of tranexamic acid (TXA) plus drain-clamping in reducing blood loss after total knee arthroplasty (TKA) is controversial. This meta-analysis aimed to identify whether combined tranexamic acid and drain-clamping was superior to TXA alone, drain clamping alone and control treatments.

METHODS

We searched the PubMed, EMBASE, Web of Science and Google databases and the Cochrane Database of Systematic Reviews. Patients prepared for primary TKA and who underwent TXA plus drain-clamping for blood loss were included in this meta-analysis. Outcomes included the need for transfusion, total blood loss, blood loss in drainage, a decrease in hemoglobin and the occurrence of deep venous thrombosis (DVT). Stata 12.0 was used for meta-analysis.

RESULTS

Finally, 7 clinical studies with 839 patients were included in this meta-analysis. Compared with the control group, TXA group and drain clamping group treatments, TXA plus drain-clamping could reduce the need for transfusion, total blood loss, blood loss in drainage and the decrease in hemoglobin with statistically significance.

CONCLUSIONS

TXA plus drain-clamping is an efficient method for controlling blood loss after TKA, and more studies should focus on the optimal clamping duration.

Perioperative Blood Management Strategies for Total Knee Arthroplasty

Total knee arthroplasty (TKA) often causes a significant amount of blood loss with an accompanying decline in hemoglobin and may increase the frequency of allogeneic blood transfusion rates. Unfortunately, allogeneic blood transfusions have associated risks including postoperative confusion, infection, cardiac arrhythmia, fluid overload, increased length of hospital stay, and increased mortality. Other than reducing the need for blood transfusions, reducing perioperative blood loss in TKA may also minimize intra-articular hemorrhage, limb swelling, and postoperative pain, and increase the range of motion during the early postoperative period. These benefits improve rehabilitation success and increase patients' postoperative satisfaction. Preoperative anemia, coupled with intraoperative and postoperative blood loss, is a major factor associated with higher rates of blood transfusion in TKA. Thus, treatment of preoperative anemia and prevention of perioperative blood loss are the primary strategies for perioperative blood management in TKA. This review, combined with current evidence, analyzes various methods of blood conservation, including preoperative, intraoperative, and postoperative methods, in terms of their effectiveness, safety, and cost. Because many factors can be controlled to reduce blood loss and transfusion rates in TKA, a highly efficient, safe, and cost-effective blood management strategy can be constructed to eliminate the need for transfusions associated with TKA.

Efficacy of tranexamic acid plus drain-clamping to reduce blood loss in total knee arthroplasty: A meta-analysis

BACKGROUND

Perioperative blood loss is still an unsolved problem in total knee arthroplasty (TKA). The efficacy of the preoperative use of tranexamic acid (TXA) plus drain-clamping to reduce blood loss in TKA has been debated. This meta-analysis aimed to illustrate the efficacy of TXA plus drain-clamping to reduce blood loss in patients who underwent a TKA.

METHODS

In February 2017, a systematic computer-based search was conducted in PubMed, EMBASE, Web of Science, the Cochrane Database of Systematic Reviews, and Google Scholar. Data from patients prepared for TKA in studies that compared TXA plus drain-clamping versus TXA alone, drain-clamping alone, or controls were retrieved. The primary endpoint was the need for transfusion. The secondary outcomes were total blood loss, blood loss in drainage, the decrease in hemoglobin, and the occurrence of deep venous thrombosis. After testing for publication bias and heterogeneity between studies, data were aggregated for random-effects models when necessary.

RESULTS

Ultimately, 5 clinical studies with 618 patients (TXA plus drain-clamping group = 249, control group = 130, TXA-alone group = 60, and drain-clamping group = 179) were included. TXA plus drain-clamping could decrease the need for transfusion, total blood loss, blood loss in drainage, and the decrease in hemoglobin than could the control group, the TXA-alone group, and the drain-clamping group (P < .05). There was no significant difference between the occurrence of deep venous thrombosis between the included groups (P > .05).

CONCLUSIONS

TXA plus drain-clamping can achieve the maximum effects of hemostasis in patients prepared for primary TKA. Because the number and the quality of the included studies were limited, more high-quality randomized controlled trials are needed to identify the optimal dose of TXA and the clamping hours in patients prepared for TKA.

Improved Intermittent-clamped Drainage in Lower Lumbar Internal Fixation: A Randomized Prospective Study

Background:

Continuous negative pressure drainage (CNPD) is widely used after lower lumbar internal fixation; however, it may cause tremendous blood loss and lead to postoperative hemorrhagic anemia. The present study explored the efficacy and safety of improved intermittent-clamped drainage (ICD) for lower lumbar internal fixation.

Methods:

This was a prospective study that included 156 patients with decompression of the spinal canal and internal fixation for the first time from January 2012 to December 2014. The patients were randomly divided into ICD group and CNPD group, and each group had 78 cases. A drainage tube was placed under the deep fascia in all patients within 10 min after the commencement of wound closure. The postoperative drainage amount at different time points, the hemoglobin level, and postoperative complications were recorded and compared between the two groups. Shapiro-Wilk test, independent samples t-test, and Mann-Whitney U-test were used in this study.

Results:

The drainage amount was significantly reduced in the ICD group, as compared with the CNPD group (Z = 10.74, P < 0.01). The mean total drainage amount (in ml) of the single-segment and two-segment procedures was significantly greater in the CNPD group than the ICD group (Z = 10.63 and 10.75, respectively; P < 0.01). For the adverse events, there was no significant difference in postoperative temperature, wound problem, and complications between the two groups.

Conclusions:

The present study showed a statistically significant reduction in postoperative drainage amount between ICD and CNPD groups, and ICD is an effective, convenient, and safe method for routine use in lower lumbar surgery. It is essential to focus on the effect of clamping drainage with long-segment surgical procedure and complex lumbar disease in the further investigation, as well as the effect of clamping on long-term functional outcomes.
