Filter by:The investigators want to know whether the intravenous ascorbic acid would reduce the blood loss during laparoscopic myoma surgery. The investigators randomized patients into intravenous ascorbic acid group and placebo group and examined the blood loss in both groups.
This is a large, community-based, cluster-randomized trial to compare routine prophylactic use of 600 mcg oral misoprostol and 10 IU oxytocin delivered by UnijectTM intramuscularly during the third stage of labor
The investigators hypothesize that octreotide LAR (Long Acting Release) safely decreases GI bleeding in patients with a left ventricular assist device (LVAD). Patients undergoing implantation of non-pulsatile, continuous-flow LVAD have a higher incidence of gastrointestinal bleeding. This is a significantly associated morbidity and can threaten a patient's life as well as their ability to undergo eventual heart transplantation secondary to both general health/strength and the potential development of antibodies to blood products that would make future transfusions and transplantations more difficult. If this research finds that use of octreotide LAR can decrease the incidence of gastrointestinal bleeding in this patient population, it will revolutionize the manner in which these patients are managed. The finding of reduced GI bleeding would allow the patient to have less exposure to blood products, reduce hospitalizations, and ensure that subsequent transplant planning not be delayed. This would not only be of great benefit to the patient, but would significantly decrease health-care costs through preventive measures. The goal of this project is to study whether the regular administration of monthly octreotide LAR is safe and if it will decrease the incidence of gastrointestinal bleeding in patients undergoing implantation of non-pulsatile, continuous flow left ventricular assist devices (LVAD).
The aim of the study is to test if intracerebral haemorrhage (ICH) patients who have contrast extravasation on computed tomography angiography, the "spot sign", have lower rates of haematoma growth when treated with tranexamic acid within 4.5 hours of stroke onset, compared to placebo.
This study was done to determine if the use of a combination of preoperative rectal misoprostol 400µg used with intraoperative perivascular vasopressin is better than perivascular vasopressin used alone to decrease bleeding at myomectomy.
The upper and lower gastrointestinal bleeding, not related to portal hypertension, is a common disorder in the elderly. Indeed, in 1996, in a French study, the median age of patients hospitalized for upper gastrointestinal bleeding was 68. During the same period in the studies reported in English the median age was 71. If epidemiological data concerning lower gastrointestinal bleeding are rare, the average age of hospitalized patients varies from 63 to 77 depending on the study. Due to improvement in endoscopic haemostatic procedures and current resuscitation methods, gastrointestinal bleeding prognosis has greatly improved, whereas anaemia related to a bleeding episode remains a frequent complication of gastrointestinal bleeding in elderly patients. Among elderly patients over 65, the prevalence of anaemia varies from 8 to 44% depending on the criteria used and populations studied. The occurrence of a bleeding episode can either induce anaemia or exacerbate pre-existing anaemia. Physicians in charge of gastrointestinal bleeding are often unaware of anaemic consequences in the elderly patients which can often be serious. Various studies have shown that anaemia increases morbidity and mortality rates in the elderly. Life expectancy is independently significantly lower for anaemic patients over 65, than for non-anaemic subjects. Anaemia is also a risk factor for the occurrence of cardiovascular and neurological complications, impairment in cognitive function and increased risk of falling. Iron deficiency and anaemia induced by bleeding episodes in patients over 65 hospitalized for upper or lower gastrointestinal bleeding should be corrected rapidly and effectively. Currently, the cost and risks of infection or cardiovascular-related complications of transfusions lead to limiting red blood cell transfusion with a goal average of 9 g/dL haemoglobin. It is also necessary to develop alternatives to massive transfusions. The correction of iron deficiency promotes erythropoiesis and can quickly correct anaemia. In clinical practice, the effectiveness of iron intake by the oral route is limited by the frequent occurrence of significant gastrointestinal side effects that limit patient compliance and limited absorption necessitating prolonged treatment to correct iron deficiency. The black colour of stools caused by taking oral iron supplements also makes it difficult to detect a possible recurrence of bleeding after hospitalization. The prescription of intravenous iron seems more suitable for a rapid and complete correction of iron deficiency after gastrointestinal bleeding. The main objective of our study is to evaluate efficacy of intravenous iron for the correction of anaemia, measured by haemoglobin at week 6 (W6) in patients aged over 65, after gastrointestinal bleeding. Secondary objectives were to assess the speed of anaemia correction, the tolerance of intravenous iron supplementation, the rate of re-hospitalization within 6 months after discharge and patients quality of life. This is a prospective multicenter randomized study versus placebo. After obtaining informed consent, all patients aged over 65 admitted with upper or lower gastrointestinal bleeding, with successful outcome, not related to portal hypertension, responsible for persistent anaemia (definition: Hb < 11 g / dL) after hospitalization will be included in the study. Patients will be treated for their bleeding event in the usual manner of each centre with target for transfusion of 9 g / dL haemoglobin. The absence of external bleeding and haematocrit and/or constant haemoglobin levels will be considered as the end of bleeding. Day 1 was arbitrarily defined as the day the patient left hospital. The protocol at Day - 1 included: obtaining informed consent of the patient, determination of iron and ferritin blood levels and complete blood count. and randomization intravenous iron injection , (Ferinject) versus Placebo. Intravenous iron injection will be performed at Day 0. A complete blood count will be performed at week 6 and month 6. Patients will be reviewed in consultation at week 6 and at month 6 to obtain related intercurrent events and assess their quality of life. The results of this study could lead to changes in the care of older patients hospitalized for gastrointestinal bleeding.
What happens in the borderzone of a cerebral hemorrhage remains widely onknown and furhter the best timing for doing MR to look for vascular pathology in cerebral hemorrhage has not yet been determined. In this study we do acute MRS, a non-invasive imaging mathod to detemine the biochemsty in the border zone and structural MRI for vascular malformation. We repeat structural MRI after 8 weeks.
Endothelin-1 (ET-1) seems to be involved in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage. However measurements of cerebrospinal fluid concentrations (CSF) of ET-1 are not sensitive enough to predict the development of vasospasm representing the average value throughout the entire cerebral circulation. Cerebral microdialysis (MD) is a technique able to detect molecule concentrations in a small perivascular area. The investigators performed a prospective observational clinical study to test the hypothesis that MD ET-1 concentrations should be a sensitive predictor for vasospasm. Patients with subarachnoid hemorrhage at high risk for vasospasm according to Fisher scale admitted to the ICU were consecutively studied. All patients received surgery within 48 hours from the bleeding; MD probe was placed in the area at risk for vasospasm after surgery and samples were hourly collected and analysed to measure lactate, piruvate and glutamate levels; ET-1 levels in CSF and MD fluids were measured from admission until day 7. At admission and after 7 days two angiographies were performed to detect the degree and extent of vasospasm, Transcranial Doppler and neurological evaluation were daily performed. Patients were then classified according to the presence of vasospasm in 3 groups: absence of vasospasm (NV), presence of vasospasm (CV), acute neurological deterioration (AND).
This study aims to assess postoperative blood loss and transfusion rates in total hip replacement after one-time administration of topical tranexamic acid.
