RESUMO
Objective To find a more suitable approach for the application of tranexamic acid(TXA)on total knee arthroplas‐ty (TKA) .Methods Totally 60 patients who met the inclusion criteria from January 2014 to August 2015 in the First Affiliated Hospital of Shihezi University were selected and divided into two groups according to the different route of administration .Group A (n=30) was intravenously injected with 100 mL TXA ,and group B(n=30) was locally injected with 100 mL TXA .Three hours drainage tubes occlusion were carried out after operation in the two groups .The intraoperative and postoperative dominant blood loss ,hidden blood loss indexes and the amount of total blood loss were recorded ,and coagulation indexes and D‐2 polymer were reg‐ularly monitored ,the incidence of thrombosis and postoperative adverse events were also observed .Results The amount of total blood loss in group B[(895 .41 ± 239 .02)mL] was lower than that in group A[(1 020 .89 ± 210 .83)mL] ,and the difference was statistically significant (P0 .05) .No blood trans‐fusion ,symptomatic deep venous thrombosis and fatal pulmonary embolism occurred in the two groups .Conclusion The hemostatic effect of local application of TXA is better than that of intravenous injection in patients′initial TKA .
RESUMO
OBJECTIVE: To investigate the clinical characteristics and associated risk factors for emergency peripartum hysterectomy classified by the amounts of blood loss. MATERIAL AND METHODS: We reviewed the medical records of 159 cases of peripartum hysterectomy among 46,666 deliveries, from Jan. 1995 to Dec. 2005 at the Dept. of Ob. & Gy. of Graduate School of Medicine, Gachon University of Medicine and Science. We divided the 159 cases into three groups based on the amounts of blood loss, which were group A as less than 2,000 mL of blood loss, group B as 2,000 to 4,000 mL of blood loss, and group C as more than 4,000 mL. The incidence, the type of delivery, the amounts of transfusion, the operative indication and the complications of peripartum hysterectomy were evaluated. RESULTS: The incidence of peripartum hysterectomy was 0.34% (159/46,666) and 0.47% in cases of cesarean section and 0.19% in vaginal delivery, respectively. There was no meaningful correlation between maternal age, parity, gestational age, hospital stay and amount of blood loss. The increments of blood loss correlated to the frequency of peripartum hysterectomy after cesarean section (p<0.05). The most common operative indication in group A was uterine atony (47.19%), and those in group B and C were adherent placentation (48.08%, 50.00%). Intraoperative and postoperative complications according to excessive bleeding were increased, and DIC, pulmonary infection, urethral and bladder injury were observed more frequently in group C than in group A. CONCLUSION: The emergency peripartum hysterectomy was related to adherent placentation and was accompanied with increased blood loss.
