Active clinical trials for "Blood Loss, Surgical"

The effect of tranexamic acid (TXA) on bleeding and improvement of surgical field during ear exploration surgery is not clear yet. This study will conducted to answer this question.

Decompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. However, it might be underestimated if the course of cognitive functions before and after cranioplasty were insufficiently documented.

Comparative study on efficacy of haemostatic therapy guided either by standard laboratory coagulation parameters or point-of-care testing in patients undergoing vascular surgical procedures. We investigate the amount of perioperative bleeding and the number of blood product used. Inclusion criteria Patients scheduled for elective and acute open aorta surgery or undergoing acute aorta surgery with minimally invasive techniques and were provided treatment in the operating theatre and/or ICU attached to perioperative care, they must be at least 18 years of age and written informed consent was obtained from the patient or his/her legal representative. Randomisation technique Patients will be randomly assigned to each of two treatment groups using sealed envelopes. In group 1 (G1) haemostasis strategy guided by conventional coagulation tests, while in group 2 (G2) transfusion algorithms guided by point-of-care (POC) tests will be carried out. Sampling techniques and measurements For assessment of monitored parameters shall be used arterial or venous blood depending on the catheter placed preoperatively. In case of the above mentioned vascular surgical procedures, all patients will receive arterial cannula routinely, and, depending on the extension of procedure, as appropriate, a central venous catheter will be inserted as well. Sampling in the patient groups shall be performed as follows: pre- and postoperative evaluation of standard laboratory parameters in all patients evaluation of standard laboratory parameters and arterial Astrup test during and after surgery in group 1, if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes in case of elective surgery: thromboelastometry and arterial Astrup test during and after surgery in group 2 if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes in case of acute surgery: thromboelastometry and arterial Astrup test before, during and after surgery in group 2 in case of positive anamnesis, preoperative platelet aggregation test in both groups Besides the above samplings, routine lab tests (blood gas, blood count, sodium (Na), potassium (K), parameters of renal and liver function, clotting and inflammation, lactic acid, blood sugar) will be performed every day as usual during intensive therapy.

This will be a multicentre, randomised, controlled and prospective clinical trial. All participants provided their written informed consent to participate in a randomized trial that examined the effects of low-level MAP (60-70 mmHg) vs. high-level MAP (90-100 mmHg) in elderly patients (65 or more years of age) during noncardiothoracic surgery under general anesthesia. The investigators hypothesise high-level blood presure of the intervention for reducing the incidence of post-operative complications.

This randomised controlled trial has a non-inferiority design. The aim is to test if the blood loss (volume in mL and hemoglobin) is effected by heart and lung cardiotomy retransfusion, or not? Forty CABG (Coronary Artery By pass Grafting) patients will be allocated to either receive retransfusion (n=20) of cardiotomy blood via the heart and lung mashine, or no retransfusion (n=20).

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.

A full medical history will be obtained from all participants. Obstetric ultrasonography and laboratory tests will be performed.According to group assignment, either 1 g(10 mL) tranexamic acid stored in a dry container at 15 °C-30 °C) diluted in 20 mL of 5% glucose or 30 mL of 5% glucose will be slowly administered intravenously 15 minutes before skin incision over a 5-minute period. Following delivery, patients in both groups will receive an intravenous bolus of 5 IU oxytocin , 1 mL(0.2 mg) intramuscular ergometrine , and 20 IU oxytocin in 500 mL lactated Ringer's solution(infused at a rate of 125 mL/h)

A phase 3 multicenter unblinded randomized controlled trial comparing the temporary uterine blood supply occlusion with conventional approach during laparoscopic myomectomy in patients with uterine leiomyoma.

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).

The purpose of this study is to assess if aprotinin (BAY A0128), given intravenously during surgery, is safe and can help reduce the amount of bleeding and the need for a blood transfusion during hip replacement surgery. Patients undergoing major surgery are at risk for significant blood loss. Because of this, there is a need for drugs that will help slow the amount of bleeding during surgery.
