Filter by:Non-invasive monitoring to measure changes in blood volume.
To determine if a manual blood loss can be detected using the non-invasive blood monitor.
Zynex's blood volume monitor (BVM) is a non-invasive monitoring device to monitor blood volume and blood loss of a patient during surgery, post operatively and/or in recovery. This monitoring device will identify baseline blood volume and relative changes in blood volume using a specific algorithm to compare and review data already monitored during surgery, displaying blood volume and blood loss in real-time.
There is no study hypothesis. The purpose of this study is to compare the accuracy of the: 1) SpHb (Radical 7 Pulse Co-Oximetry with SpHb™) RevF sensor (currently marketed), 2) the SpHb RevG sensor (a new, limited release version), and 3) the Pronto-7 sensor (currently marketed version) in patients undergoing spine surgery.
Total knee arthroplasty is often associated with excessive postoperative bleeding due to increased fibrinolysis. Hence, the objective of the proposed of this multicentre study is to determine the peri-operative bleeding comparing the application of topical and intravenous tranexamic acid with the habitual surgical haemostasis.
This study was designed to evaluate the efficacy of leucocyte free autologous platelet rich plasma on blood loss, pain, wound healing and functional outcome after total knee arthroplasty. The investigators hypothesized that application of platelet rich plasma would help in reducing blood loss, postoperative pain and expedite wound healing and better short-term functional outcome following total knee arthroplasty.
The purpose of this study is to measure the effect of fibrin sealant on reducing blood loss, pain and swelling when operated for bilateral total knee arthroplasty. Likewise the effect on Range Of Movement (ROM) and strength is examined.
In order to prevent excessive blood loss during liver surgery, an intermittent Pringle manoeuvre (IPM) can be applied. This implies a temporary clamping of the portal vein and hepatic artery in the hepatoduodenal ligament in order to occlude hepatic inflow. The optimal duration of the IPM is unknown. This randomized controlled trial aimed to analyse differences in hepatocellular damage after 15 minutes or 30 minutes IPM during liver surgery for primary or secondary liver tumours.
Sevoflurane is an FDA-approved anesthetic drug commonly used for anesthesia during second trimester abortion procedures. It has a few advantages, including ease of use by the anesthesia provider. However, the literature suggests that when used in doses higher than those used at Oregon Health & Science University (OHSU) and Lovejoy, it is associated with an increase in the risk of bleeding. The investigators study aims to test whether the lower dose used at OHSU and Lovejoy during second trimester abortion procedures causes any difference in blood loss, when compared to similar abortion procedures for which this drug is not used.
The purpose of this study is to look at red blood cell (RBC) transfusions in trauma patients and evaluate for any differences between the age of the RBCs and how they were stored. The investigators will specifically look for the following differences between study groups: 1. the transfused red blood cells' ability to delivery oxygen to the tissues 2. differences in biochemical markers in subjects and units transfused, and 3. how the subject's internal organs are working and if they develop any infections
