Filter by:Although, suction drainage is routinely used in orthopedic clinical practice, there are still no precise guidelines on its use in total joint arthroplasty, particularly in total as well as unicompartmental knee arthroplasty. In fact, drain use is likely associated to an increased risk of blood transfusion due to the lack of tamponade effect, as well as a higher infection rate. Furthermore, the drain itself could interfere with knee mobilization, delaying its functional recovery. Thus, the aim of this study was to investigate the real usefulness of suction drainage in perioperative bleeding control in the management of total as well as unicompartmental knee arthroplasty.
The primary objective of this multicentric observational study is to define the role of intraoperative temperature decrease (defined as reduction of at least 1 ° C during surgery) as haemorrhagic risk factor, evaluated as reduction of at least 1 gr / dl of hemoglobin, and to correlate it with the need for transfusion. Secondary objectives are infections and complications affecting other organs and systems incidence in the first week after surgery.
- The primary endpoint is the effect of the addition of oral Diltiazem and Tranexamic Acid to general anesthesia aided reduction in blood loss during functional endoscopic sinus surgery (FESS). - The secondary endpoint is surgeon's assessment of the surgical field and hemodynamics.
Study Design: Randomized Controlled Clinical Trial. Study Population: The study population will be a consecutive series of participants attending the Early Cancer Detection Unit (ECDU) at Ain Shams University Maternity Hospital. 80 women who are scheduled to undergo a hysteroscopic myomectomy will be included and will be randomized into two groups: Group A: women will undergo a hysteroscopic myomectomy with the use of (TXA) Kapron in the distention medium Group B: women will undergo hysteroscopic myomectomy with the use of placebo(normal saline in the distention medium). Randomization will be performed using a Computer-generated randomization system. The allocated groups will be concealed in serially-numbered sealed opaque envelopes that will only be opened after recruitment. Patient allocation will be performed prior to the induction of anesthesia by an independent person, who will not otherwise be involved in this study. The trial will be appropriately blinded; the participants, outcome assessors and the surgeon performing the procedure will be blinded to the medication type, which will be used inside the distention medium. Therefore, this study will be a randomized double blind prospective clinical Methodology: 1. Informed written consent obtained from the participant. 2. History 1. Personal history 2. Menstrual history 3. Detailed obstetric history 4. Surgical intervention especially uterine surgeries and any post-operative complication 5. History of drug intake, especially hormonal treatment or anticoagulant therapy. 3. Routine preoperative investigations in addition to a serum pregnancy test if pregnancy is suspected. 4. Physical examination including general, abdominal and pelvic examination. 5. Hysteroscopy will be performed in the early proliferative phase using normal saline as a distention medium. 6. Only in intervention group (TXA group) KAPRON (Tranexamic acid) will be added to the injected media. - In intervention group 500 mg of Kapron for every 500 ml of distending media will be added. - In the control group, placebo .i.e. ,normal saline in the same form will be injected inside every 500 ml of the distention medium. 7. The trial will be appropriately blinded; the participants, outcome assessors and the surgeon performing the procedure will be blinded to the medication type, which will be used inside the distention medium. Therefore, our study will be a randomized double blind prospective clinical trial. 8. Intraoperative bleeding and quality of view will be observed. 9. A blood sample will be taken from each participant in both groups after 24 hours from the end of the operation for both hemoglobin and hematocrit levels. Types of outcome measures: Primary outcome measures: Estimated Blood loss defined as comparing the hematocrit and hemoglobin at base line (preoperative ) and 24 hours after surgery with the Tranexamic acid compared to the control group. Secondary outcome measures: The quality of view, duration of surgery, the volume of injected media, intraoperative complications and the success of the completion of the operation will be secondary outcomes.
Major lung resection is one of the most common procedures performed in thoracic surgery, but it may involve considerable bleeding and the occasional need for a transfusion and/or reoperation for bleeding in specific cases. In addition, lysis of pleural-parenchymal adhesions and dissection can represent a challenge in patients who have undergone chemotherapy and/or radiation therapy, and in patients with bronchiectasis or COPD. Several intraoperative methods have been used to manage blood loss, including topical haemostatic agents, bipolar sealers or electrocautery. Transcollation technology (TT) consists of a disposable bipolar sealer that uses a radiofrequency coagulation system to deliver a saline solution that provides haemostatic sealing of soft tissue and bone and provides localized cooling without charring. Blood loss reduction has been previously described in several fields of surgery. The primary end-point of the proposed trial is to assess if the ability of Transcollation Technology in reducing the proportion of patients showing bleeding perioperatively within the setting of a prospective randomized controlled trial. The secondary end-point is to assess if Transcollation Technology is able to improve postoperative outcomes reducing the length of hospital stay.
The purpose of the study is to determine whether volume therapy with a solution of gelatine has negative impact on coagulation, platelet function, renal function in comparison with crystaloid solution (Ringerfundin).
