ObjectiveTo compare the effectiveness of haemocoagulase agkistrodon and tranexamic acid and sodium chloride in the prevention and treatment of perioperative bleeding in a real world setting. MethodsA research database was constructed based on the records of inpatient visits using haemocoagulase agkistrodon and tranexamic acid and sodium chloride according to the SuValue? database from January 1, 2016 to December 31, 2020. The patients were divided into two groups according to the different interventions. After matching with a 1∶1 propensity score, the effectiveness of two groups was compared. ResultsA total of 858 patients were included in each of the two groups, and there was no statistically significant difference in baseline characteristics between the two groups (P>0.05). Research results showed that patients using haemocoagulase agkistrodon had significantly reduced length of hospital stay, decrease in hematocrit, average estimated surgical bleeding, and decrease in hemoglobin (P<0.01). ConclusionHaemocoagulase agkistrodon has better effectiveness than tranexamic acid and sodium chloride for reducing perioperative blood loss based on current real world evidence.
ObjectiveTo evaluate the efficacy and safety of all kinds of hemocoagulase on operative incisions.
MethodsDatabases including Web of Science, MEDLINE, EMbase, EBSCO, PubMed, CNKI, WanFang Data and VIP were electronically searched to collect randomized controlled trials (RCTs) about hemocoagulase on operative incisions from the inception to June 20th, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.2 software.
ResultsA total of 16 RCTs involving 1 867 patients were included. The results of meta-analysis showed that, compared with the control group, the hemostatic time (MD=-37.84, 95%CI -52.72 to -22.96, P<0.000 01), blood loss volume per unit area (MD=-0.09, 95%CI -0.10 to -0.07, P<0.000 01), PT of the first postoperative day (MD=-0.37, 95%CI -0.65 to -0.09, P=0.009) were significantly shorter in the hemocoagulase group. However, no significant differences were found in APTT, TT and FIB between two groups.
ConclusionHemocoagulase can reduce hemostatic time and blood loss volume in surgical incisions. Due to the limited quantity and quality of the included studies, the above conclusion needs to be further verified by more high quality studies.
