Filter by:The study´s aim is to evaluate the clinical applicability of the Feature Extraction Technology (FET) during a simulated blood loss scenario.
Exploratory tympanotomy is surgical access to the middle ear, made for diagnosis and management of unexplained conductive hearing loss, performed under an oto-microscope across the external auditory canal after tympanic membrane elevation to explore the middle ear structures
This study compares two oral medications (tranexamic acid and aminocaproic acid) as hemostatic agent administered in patients undergoing primary total hip replacement
The objective of this research is to compare the effect of irrigation during impacted mandibular third molar surgery, with normal saline of 25 ± 2 ° C and 37 ± 1 ° C for control and experimental sides, respectively.
This study will monitor coagulation parameters during the perioperative course of cancer surgical procedures using the Quantra System with the QPlus Cartridge.
This study will assess the clinical performance of the Quantra System with the QStat Cartridge in the liver transplant population.
Middle ear surgeries utilizes microscope in a narrow field. They are better performed under controlled hypotension, to minimize bleeding and improve surgical field visualization and hence improve results.Head-up or anti-trendelenburg position influences intraoperative bleeding by generating regional ischaemia in sites elevated above the level of the heart. Also by augmenting the effect of vasodilators through pooling of blood in dilated veins.
Preoperative anemia is associated with an important increase in transfusions of red blood cells (RBC) compared to a non-anemic patient in cardiac and non cardiac surgery. Furthermore transfusion is also an independent factor of morbi-mortality with notably an increase in the infectious risk, immunological, an increase of the risk of cardiac decompensation, respiratory decompensation Transfusion Related Acute Lung Injury (TRALI) or Transfusion Associated Cardiac Overload (TACO), and an increase in mortality of 16%. Management of perioperative transfusion is therefore a public health issue. Since 2010, the World Health Organization (WHO) has been promoting a systematic approach to implement blood management programs for the patient to optimize the use of resources and promote quality and safety of care. Improving the relevance of transfusion in cardiac surgery could be achieved by optimizing the management of patients around 2 axis: A:non-drug intervention : Review of Practices to Improve the Management of Perioperative RBC Transfusion B:drug intervention : Systematic correction of pre- and postoperative iron, vitamin deficiencies and anemia The aim of this program is to improve the relevance of transfusion in cardiac surgery and to limit the morbidity and mortality induced by transfusion. This program is part of a global project of pre, per and postoperative management of the patient undergoing cardiac surgery programmed under extracorporeal circulation (ECC). It requires a multidisciplinary approach between cardiologists, anesthesiologists and intensivists, perfusionists, cardiac surgeons and paramedical teams to optimize the management of the patient.
Purpose: The study aimed to determine whether intravenous administration of tanexamic acid (TXA) before shoulder arthroscopic rotator cuff repair surgery can improve arthroscopy visual clarity. Methods: This is a prospective, double-blinded, randomized and placebo-controlled study. From May 2016 to April 2018, patients requiring arthroscopic rotator cuff repair were enrolled and randomly assigned to either the TXA group that received 1000mg tranexamic acid intravenously 10 minutes before surgery or the placebo group that received the same volume of plain saline. Patients with pre-existing liver/renal disease, coagulopathy, or concurrent use of anti-coagulation medications were excluded. The visual clarity was rated by a numeric rating scale from grade 1(poor) to grade 3(clear) every 15 minutes throughout the surgery. Secondary outcomes included estimated perioperative blood loss, operative time, degree of shoulder swelling, postoperative subjective pain score, inpatient duration and associated comorbidities were recorded. Both parametric and nonparametric methods were used for statistical analysis.
Need for perioperative blood transfusion is still high in certain types of oncological abdominal surgery. Allogeneic blood transfusion may be detrimental in cancer patients undergoing a potentially curative resection of malignant tumor, although the detailed mechanism of this effect is still under debate. We plan to evaluate whether a new, rotational thromboelastography-guided algorithm (ROTEM) to guide hemostatic resuscitation intra-operatively decreases the use of allogeneic blood products, the total amount of bleeding, transfusion related side effects, thromboembolic complications and costs. Its effect on each patient's post-operative hemostatic profile is also measured. 60 patients having a potentially curative pancreaticoduodenectomy (or resection of cauda of pancreas), total removal or partial resection of kidney and open radical cystectomy are recruited when an active blood loss of more than 1500 ml is estimated and/or measured and are randomized into two groups: one will be treated conventionally, ie. using massive transfusion protocol (MTP) if necessary, clinical judgement and conventional coagulation tests, the other treated using a ROTEM-based algorithm.
