The purpose of this study was to compare the efficacy of intravenous and topical tranexamic acid (TXA) versus control group for reduction in blood loss following primary total knee arthroplasty (TKA). A total of 90 patients were prospectively allocated to each of three groups (control, intravenous IV and intra-articular) and underwent unilateral total knee arthroplasty. In the IV group, patients received one dose of TXA of 15 mg/kg before deflation of the tourniquet, while in the intra-articular group patients received 2 g TXA via the drain retrogradely after closure of the wound. The mean drained blood loss in control, IV and intra-articular groups was 415 ± 24, 192 ± 21 and 121 ± 17 ml, respectively. About 43 % (control), 23 % (IV) and 17 % (intra-articular) of each group required transfusion, and the mean transfusion was 338, 168 and 79 ml, respectively. Preoperative hemoglobin values decreased at 24 h by 2.80 ± 0.14, 2.24 ± 0.17 and 2.26 ± 0.18 mg/dl, respectively. TXA reduced blood loss and transfusion requirement. Compared with one-dose intravenous administration, intra-articular administration of TXA seems to be more effective in terms of reducing drained blood loss and transfusion frequency. We recommend administration of topical TXA in primary TKA in healthy patients to decrease perioperative blood loss.

“…Second, a proportion of blood loss after surgery is hidden. The volume of hematomas is difficult to estimate clinically or by ultrasonography, although several methods and indices for calculation of hidden blood loss have been proposed [20,26]. However, any underestimation of such masked blood loss should be equally distributed randomly in groups.…”

“…We recorded the number of blood transfusions and plasma substitutes. The primary outcome was the volume of blood loss measured by weighing sponges and drapes (1 mg = 1 mL), volume in suction drains during surgery, and wound drains until removal 24 hours postoperatively [20]. We also recorded the number of patients who received transfusions, consumption of units of allogeneic leukodepleted erythrocyte concentrate, and decrease in hemoglobin concentration postoperatively in the two groups.…”

Background Thrombin formation commences perioperatively in orthopaedic surgery and therefore some surgeons prefer preoperative initiation of pharmacologic thromboprophylaxis. However, because of the potential for increased surgical bleeding, the postoperative initiation of thromboprophylaxis has been advocated to reduce blood loss, need for transfusion, and bleeding complications. Trials on timing of thromboprophylaxis have been designed primarily to detect thrombotic events, and it has been difficult to interpret the magnitude of blood loss and bleeding events owing to lack of information for bleeding volume and underpowered bleeding end points. Questions/purposes We therefore asked whether there are differences in blood loss, transfusion requirements, and other postoperative clinical complications with preoperative versus postoperative start of thromboprophylaxis with dalteparin. Methods In a double-blind, randomized controlled trial, 80 patients undergoing primary cemented THA were allocated to dalteparin injections starting 12 hours before or 6 hours after surgery. Blood loss was measured by weighing sponges and drapes, volume in suction drains during surgery, and wound drains until removal 24 hours postoperatively. Hemoglobin and hematocrit were recorded at predefined times during and after surgery. Results We found no differences in blood loss (1081 mL ± 424 mL versus 1023 mL ± 238 mL), bleeding-related events (10% versus 17%), or number of patients who had transfusions (12 versus five) with preoperative and postoperative thromboprophylaxis, respectively. Other complications were few in both groups. Conclusions Our data suggest blood loss is similar with preoperative and postoperative initiation of dalteparin thromboprophylaxis, but indicate a trend toward fewer transfusion requirements which might favor postoperative start of thromboprophylaxis.

Ovarian cysts are benign tumors in women of childbearing age, and symptomatic ovarian cysts account for about 7%. 1 Asymptomatic or small ovarian cysts do not usually require clinical intervention.However, when an ovarian cyst ruptures, undergoes torsion, or has adverse effects such as infertility, it requires surgical intervention. 2,3 Laparoscopic cystectomy has become a recognized treatment for ovarian cysts. 4 The advantages of laparoscopic surgery over laparotomy have been well demonstrated, including better intraoperative visualization, smaller incision, less blood loss, fewer postoperative complications such as wound infection, shorter hospital stay, and faster recovery. 5 Laparoendoscopic single-site surgery (LESS) has been developed and gradually applied in clinical practice. One of the obvious advantages of LESS is that the larger umbilical incision is helpful for the surgeon to remove the cysts from the abdominal cavity. 6 It
