Filter by:This study will be a prospective cohort study. Patients who meet criteria for inclusion in the study will be approached for participation at same day of admission. Written informed consent will be obtained from the patients by the Co-principal investigator and by the study collaborators. If patients agree to participate, a CBC (complete blood count) will be obtained via venous puncture routine in our facility as part of the admission labs which will be around 10 cc of blood. The device will be used during the delivery in laboring room. The device will be used to assess QBL (quantitative blood loss) by the research staff only and results/ QBL assessment will be masked to the clinical team. Unmasking will only occur following study completion with purpose to perform data analysis. Patient management will be according to the clinical team without the knowledge of the QBL. All patients undergo a CBC postpartum as part of post-partum evaluation, this will also be performed by venipuncture where 10 cc of blood will be collected. The drop in Hgb (hemoglobin) between the pre and post partum CBCs will be calculated for each patient. The post-partum CBC will be collected approximately 24-30 hours from delivery as standard in our unit. The blood will be collected from each patient by the nursing staff who are experienced in withdrawing blood. Patients will be divided into quartiles of Hgb. Cases will be those patients whose Hgb is in the upper quartile, while controls will be those patients whose Hgb is in the lower 3 quartiles. We will be comparing visual EBL (estimated blood loss) by standard clinical assessment versus the QBL result from the device between cases and controls. The Triton L&D (labor and delivery) system which comprises of the device, software analysis and staff training will be supplied by the manufacturer free of charge. Research staff will be trained by the manufacturer. We will be offering our skills, fellows, midwifes and residents, who will be collecting data and we will be performing the data analysis. Results will be available to the manufacturer after results are completed. The results of this study will be presented in conferences or published in a peer-review journal. Demographic information will be obtained from the electronic medical record. The data will be kept on a password secured University of Texas Medical Branch (UTMB) computer. An encrypted USB flash drive will be used to transfer data. The data will be identified and linked to the patient using the medical record number. During data analysis, all patient identifiers will be deleted.
This research study aims to study the use of tranexamic acid (TXA) in total joint replacement (arthroplasty) of the hip (THR) and knee (TKR).
The primary objective of this study is to assess the safety and efficacy of Tranexamic acid (TXA) in reducing blood loss and transfusion requirements for patients with osteoporotic hip fractures. In addition to assessing blood loss in these patients, complications associated with TXA use would be characterized including systemic (pulmonary embolism, deep venous thrombosis, myocardial infarction, stroke) and surgical site (hematoma, infection) events, need for re-hospitalization or re-operation and 30 day mortality.
Massive bone tumour resection is often associated with important postoperative bleeding. This may determine systemic (anaemia), as well as local complications (wound healing, seroma, haematoma). The objective of this study is to determine whether the use of topical tranexamic acid or topical Evicel® will reduce the perioperative bleeding comparing it with usual haemostasis.
The primary purpose of this study is to assess the accuracy of the newly released Masimo SpHb Butterfly Sensor with RevK version and compare the results to a blood hemoglobin level analyzed in the UCSF Clinical Laboratories. A secondary purpose is to assess the blood hemoglobin using the Masimo Pronto-7 hand-held device immediately prior to surgery.
Misoprostol is a medication used extensively in obstetrics and gynecology for its ability to aid in softening the cervix as well as decreasing blood loss after abortion or vaginal delivery. Opinions vary as to its usefulness in aiding in cervical dilation, and in decreasing blood loss. The investigators propose to conduct a randomized, placebo-controlled trial to evaluate whether misoprostol given buccally 2 hours prior to second trimester surgical abortion decreases blood loss from the procedure. The investigators will also assess whether misoprostol improves cervical dilation, changes the length of the procedure, changes the need for additional mechanical dilation, changes the subjective ease of the procedure, and changes a woman's pain.
The purpose of this study is to compare standard of care hemostasis techniques with and without the use of Aquamantys in reducing peri-operative blood loss.
