Filter by:The purpose of this research is to determine if the oral form of a medication (tranexamic acid) to reduce bleeding can be used in place of an intravenous (IV) form, to learn the best way to give tranexamic acid: either a pill by mouth, or a solution by vein.
Randomized study evaluating the role of tranexamic acid in reducing intraoperative bleeding in palatoplasty.
The primary purpose of this study is to evaluate the quality of blunt dissection during abdominal and pelvic surgery involving dissection of adhesions, separation of blood vessels and neurovascular structures while preserving the integrity of these structures.
The purpose of the present study was to compare some hematologic parameters and operation time in patients who underwent esthetic bimaxillary surgery under hypotensive anesthesia.
This is a prospective, multicenter, multidisciplinary, controlled clinical investigation evaluating the safety and efficacy of PerClot in achieving intraoperative hemostasis compared to a similar marketed hemostatic device. Three hundred and twenty four subjects across a maximum of 25 investigational sites undergoing open elective cardiac, general, or urological surgical procedures who meet the eligibility criteria will be intraoperatively randomized to receive no more than the entire contents of up to two 5 gram bellows of either the investigational device or a control hemostatic agent on a bleeding site, whose anatomic site is smaller than or equal to 25cm² and whose anatomic application site is smaller than or equal to 47cm², when bleeding is within the pre-defined bleeding severity range after any applicable conventional means for hemostasis are attempted as specified in the intraoperative procedures. Each investigational site is expected to enroll approximately 13-40 subjects. All investigational sites will be located in the U.S. Follow-up will occur at hospital discharge and 6 weeks post-device application. For oncologic subjects, an additional follow up will occur at 24 months post device application.
The purpose of this study is to determine whether tranexamic acid is effective in reducing intraoperative blood loss and necessity for haemotransfusion in patients undergoing open abdominal aortic aneurysm repair
Purpose of the study: - To evaluate the effect of tranexamic acid (TXA) of intraoperative blood loss in patients subjected to bi-maxillary orthognathic surgery - To evaluate the potential effect of TXA on fibrin structure - To evaluate the potential effect of TXA of binding of plasminogen to fibrin - To evaluate the potential effect of TXA on postoperative edema formation. Hypothesis: H0: Intraoperative bleeding cannot be significantly reduced by preoperative administration of tranexamic acid H0,1: Postoperative edema cannot be significantly reduced by preoperative administration of tranexamic acid
Gastric cancer as one of the most common gastrointestinal cancers, radical resection of primary lesions combined with dissection of regional lymph-nodes is acknowledged by surgeons all over the world. By the invented and adopted energy surgical instruments, surgical procedure is safer and easier than before. The newly surgical instruments reduce the post-operative mortality and morbidity combined easy procedures of surgery. As the most popular instruments used in the gastric surgery, ultrasonic scalpel and monopolar electrocautery were received lots of attention and concern. Some studies have shown some advantage of the two instruments, which were they can facilitate the surgical treatment and make the surgery safer and more effective. Although, some small retrospective sample reports claimed that ultrasonic scalpel brought benefit in blood loss, dissection lymph-node intraoperative complications and even postoperative complications. And Korea small sample randomized controlled trail presentation that ultrasonic scalpel can reduced blood loss and surgical duration. However, postoperative complications were with no statistical significance between the two instruments. Cost- effective analysis of the energy instruments is still controversial. Large sample randomized control trail with high quality is needed. By the reasons above, a multicenter randomized controlled trial conducted by 9 hospitals from North to South in China aims to compare the clinical characteristics and outcomes, when using of the ultrasonic scalpel or monopolar electrocautery in traditional open gastrectomy. The aim of this study is to evaluate the outcomes of ultrasonic scalpel compared with monopolar electrocautery in D2 distal gastrectomy, include, intraoperative parameters, postoperative complications, cost data, and post-operative quality of life.
To the Investigators' knowledge, TXA has not been studied in the setting of reverse total shoulder arthroplasty. We propose a double-blinded, randomized, controlled trial comparing perioperative administration of TXA to placebo in the setting of RTSA. The purpose of this study is to examine the efficacy of TXA in reducing overall blood loss and transfusion rates in patients undergoing reverse total shoulder arthroplasty.
The purpose of the present study is the clinical assessment of the efficacy of preincisional peritonsillar infiltration of dexmedetomidine on postoperative pain relief in children undergoing adenotonsillectomy.
