Retrospective study to evaluate if FIBTEM predicts the amount of postoperative bleeding in total knee replacement patients.
After surgical procedures, interventions to reduce postoperative bleeding are of great importance. In this study, the effect will be investigated of administering tranexamic acid, which is designed for injection, directly onto the raw wound surface (topical application) created during surgery. In this way only a small amount of drug is to reach a large wound area. There will be a higher drug concentration of it in the exposed wound surface than after injection, but only a very low concentration in the body, and no risk of injury from needles. The researchers have recently shown that topically applicated tranexamic acid reduces bleeding in women who had two-sided breast reduction surgery. Now it will be studied whether topically applicated tranexamic acid reduces bleeding from superficial wounds, using as a study model the homogenous wounds created by tangential skin excision when harvesting split skin grafts for skin transplants. Two identical wound surfaces in the same patient will serve as case and control.
Total knee arthroplasty (TKA) is one of the most successful procedures in orthopaedic surgery. Nevertheless, significant postoperative blood loss and requirement of blood transfusion are still problematic. Total blood loss in TKA can be divided into visible and invisible blood loss. Visible blood loss (VBL) means blood loss from the surgical field and wound drainage while invisible blood loss (IBL) means residual blood in the knee, extravasation into the tissues and loss due to haemolysis. In usual practice, TKA is performed with a bloodless field using a tourniquet. Thus intraoperative blood loss can be negligible and postoperative drainage is only considered as VBLvisible. In terms of IBL, Sehat et al. found that TKA carried a substantial IBL. Their results shown the mean IBL was 765 ml or 49% of the mean total blood loss after TKA. Therefore, the true total blood loss was underestimated if not takes IBL into account. Modified Robert Jones bandage (MRJB) is a bulky compressive dressing that often used in orthopaedic practice. Various techniques of application have been proposed. From the previous study, MRJB could make and maintain the anterolateral muscle compartment pressure for at least 24 hours after TKA. Therefore, theoretically, this bandage can cause the tamponade effect that helps to reduce tissue edema and postoperative bleeding especially IBL after TKA. However this potential benefit of MRJB is unclear and the use of this bandage after TKA is still controversy in clinical practice.
Hepcifer Trial is designed to assess the value of iv iron administration immediately after liver surgery and consequences of inflammation on iron balance. Fifty patients will be randomized in two treatment groups. Patients will be assigned to receive either iv iron or placebo immediately after liver resection surgery. Biological inflammation parameters, hemoglobin, serum iron and hepcidin levels will be assessed prior to surgery and at day 1, 3, 7, 15 and 30 after surgery.
After surgical procedures, interventions to reduce postoperative bleeding are of great importance. In this study, the effect will be investigated of smearing tranexamic acid, which is designed for injection, directly onto the raw wound surface (topical application) created during surgery. Topical application allows a small amount of drug to reach a large wound area, higher drug concentration in the exposed wound surface but very low concentration in the body, and no risk of injury from needles. The researchers have recently shown that topically applicated tranexamic acid reduces bleeding in women who had two-sided breast reduction surgery. Now it will be studied whether topically applicated tranexamic acid reduces bleeding after breast surgery for breast cancer. After surgery for breast cancer patients may also experience problems with long lasting seroma. Therefore it will at the same time be investigated whether topical tranexamic acid reduces the development of seroma in these patients.
In this randomized, double-blind control trial to evaluate the effect of ketorolac given at the time of cord clamp has on estimated blood loss and postcesarean pain control. Patients will be randomized to either placebo or ketorolac prior to surgery. Those randomized to ketorolac will receive ketorolac at cord clamp and three additional doses every 6 hours (total 4 doses/24 hours). Those in the placebo group will receive normal saline during those time periods. Our primary outcome is to assess whether intra-operative ketorolac increases the estimated blood loss during Cesarean delivery.
A randomized, prospective, placebo-controlled study which aims to evaluate the effect of combined intraarticular and intravenous Tranexamic acid on total blood loss following unilateral knee replacement versus only intravenous tranexamic acid.
The main hypothesis of this clinical trial is that the use of intra-articular tranexamic acid and the fibrin glue plus usual hemostasis will reduce at least a 25% the postoperative blood loss with respect to usual hemostasis in patients undergoing subcapital femoral fractures.
The aim of the work is to evaluate & compare the effectiveness of rectally administered PGE1 synthetic analogue (misoprostol) 400 microgram versus sublingually administered misoprostol before caesarean section to decrease blood loss during and after the operation.
