Abstract Background This meta-analysis was conducted to investigate the evidence for the efficacy and safety of intrapericardial tranexamic acid (TXA) in cardiac surgery. Methods We searched MEDLINE from 2000 to 2017 for randomized controlled trials that compared intrapericardial TXA to placebo. We performed a meta-analysis for the eligible trials that focused on chest tube drainage measured during the first 24 hours after surgery as a primary outcome. We also examined the secondary outcome measures of these trials such as the incidence of transfusion requirements following surgery and the evidence for any increase in complication rates. Results A total of seven randomized controlled trials (six on-pump and one off-pump) comparing topical application of TXA to placebo in 692 patients were eligible for the blood loss outcome data. These trials randomized 372 patients to receive TXA and 320 patients as controls. The use of intrapericardial TXA was associated with a considerable reduction in 24-hour blood loss in all seven studies and a weighted mean difference of −343.56 mL (95% confidence interval: −316.41, −370.72) significantly differed from zero (p = 0.005) with a heterogeneity of I 2 = 0%. The incidence of packed RBC transfusion in TXA patients was significantly lower in one study and was not significant but with trend in favor of TXA in five out of the six studies in which it was reported. In one trial, TXA was not detected in any patient and in another the studied groups were similar in postoperative complications, such as graft patency, myocardial infarction, cerebral infarction, atrial fibrillation, seizures, and infections. Conclusions Findings from this meta-analysis suggest that intrapericardial use of TXA in patients undergoing cardiac surgery can decrease postoperative bleeding without increasing the risk of postoperative seizures. Future large randomized, double-blind, controlled clinical trials are needed to confirm these promising findings.

Abstract PurposeThe efficacy and safety of topical fibrin sealant (FS) compared with tranexamic acid (TXA) to reduce blood loss after total hip arthroplasty (THA) is not clear. A meta-analysis was conducted to evaluate the efficacy and safety of topical FS versus topical or intravenous TXA for treatment of primary THA.MethodWe searched electronic databases, including PubMed, Embase, and the Cochrane Library to identify studies up to March 2020. The references included in articles were also checked for additional potentially-relevant studies. The language of publication was limited to English. The endpoints included the mean difference (MD) of blood loss, hemoglobin value, and odds ratios (ORs) of transfusion requirements and thrombotic events. Our meta-analysis was performed according to the Guidelines of the Cochrane Reviewer's Handbook and the PRISMA statement. The data of the included studies were analyzed using RevMan 5.3.ResultsA total of four studies (two randomized controlled trials and two non-randomized controlled trials) met the inclusion criteria. Our meta-analysis demonstrated that TXA administration led to significantly different outcomes in terms of transfusion rate (RD = -0.12, 95% CI (-0.23, -0.00), P = 0.05, I2 = 74%) and postoperative hemoglobin levels (WMD = -0.47, 95% CI (-0.74, -021), P = 0.0005, I2 = 3%) compared with topical application of FS in patients undergoing THA. No significant difference was seen in total calculated blood loss (WMD = -86.22, 95% CI (-99.13, -73.31), P < 0.00001, I2 = 96%) or complication rate (RR = 0.98, 95% CI (-99.13, -73.31), P = 0.45, I2 = 0%) between the two groups.ConclusionsTXA administration can effectively decrease the transfusion rate and result in higher postoperative hemoglobin levels without increasing the rate of infection.

Objective. To systematically evaluate the clinical efficacy of Xueshuantong injection (Panax notoginseng saponins) in preventing deep venous thrombosis (DVT) of lower extremity after orthopedic surgery. Methods. The randomized controlled trials (RCTs) of Xueshuantong injection in prevention of lower extremity DVT after orthopedic surgery were retrieved from CNKI, Wanfang database, VIP, PubMed, and Cochrane Library by August 2020. Revman5.2 was used to analyze the results. Results. A total of 20 articles including 2336 patients were included. The results of meta-analysis showed that the incidence of DVT in the experimental group was lower than that in the control group; after operation, the D-dimer (Ddimer), thrombin time (APTT), and prothrombin time (PT) in the experimental group were significantly improved compared with those in the control group, and the difference between the two groups was statistically significant. Conclusion. Xueshuantong injection can effectively prevent the formation of lower extremity DVT after orthopedic surgery and antagonize the postoperative hypercoagulable state of blood, which has high clinical value.
