Active clinical trials for "Hemorrhage"

Acute gastrointestinal bleeding is a common medical problem. When patients with gastrointestinal bleeding present with melena (dark, tarry stool) the blood loss is usually originating in the upper gastrointestinal tract (esophagus, stomach or duodenum) and first step in evaluating the patient is an upper endoscopy; which allows direct visualization of the esophagus, stomach and duodenum. However, the cause of bleeding is located in the small bowel or colon in 20-30% of patients who present with melena. Traditionally colonoscopy has been the next test preformed if upper endoscopy does not identify the cause of melena/ gastrointestinal bleeding, however less than 25% of patients who present with melena have bleeding originating in the colon, and the remainder of patients have bleeding originating in the small intestine, which can only be fully evaluated with video capsule endoscopy (a pill camera which is swallowed and takes pictures while it travels thought the small bowel and colon). Currently patients only undergo video capsule endoscopy if colonoscopy does not identify the cause of bleeding. The investigators are preforming a randomized study which seeks to determine if colonoscopy or video capsule endoscopy is a better way to identify the cause of gastrointestinal bleeding in patients who present with melena and have normal findings on upper endoscopy. To do this the investigators will enroll patients who present with melena prior to their upper endoscopy and if the cause of bleeding is not identified at that time patients will be randomized to video capsule endoscopy (with the capsule being placed into the small bowel during the upper endoscopy) or next day colonoscopy.

The present randomized controlled trial evaluates the efficacy and safety of BioFoam® Surgical Matrix in patients undergoing elective liver resection. In contrast to other topical agents, the surgical adhesive BioFoam® Surgical Matrix may not only accelerate hemostasis but also facilitate sealing of bile ducts and thus has the potential to reduce the incidence of postoperative complications. The primary objective of this trial is to show that time-to-complete hemostasis can be reduced using BioFoam® Surgical Matrix as compared to the conventional approach.

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.

Tourniquets are still widely used in total knee arthroplasty, but are associated with several adverse effects. Most of previous studies did not randomize the participants so the baseline difference of the patients might have influenced the outcome. Therefore, investigators conducted a randomized controlled trial, in which all the patients received staged bilateral TKA with two different durations of tourniquet use. Investigators aimed to quantify the effect of tourniquet use on reducing blood loss and to evaluate the impact of tourniquet use on functional and clinical outcome.

Acute upper gastrointestinal bleeding is a common medical emergency. Bleeding peptic ulcers and other non-variceal causes constitute to about 95% of all cases of bleeding. Endoscopic treatment stops active bleeding, reduces rate of further bleeding and leads to improved patients outcomes. Endoscopic treatment can be technically demanding especially with lesions in difficult anatomic positions and to endoscopists with less experience. TC-325 is a propriety mineral blend hemostatic powder used to compress external civilian and military traumatic injuries. Investigators reported the first endoscopic application of TC-325 in 20 patients with actively bleeding gastro-duodenal ulcers. Investigators were able to stop bleeding in 19 of them. Subsequent case series from others reported a similar rate in the acute control of bleeding. To further define the role of TC-325 as a mono-therapy, a comparison to the current standard in endoscopic treatment is required. A non-inferiority randomized trial is being proposed to compare endoscopic use of TC-325 as a mono-therapy to current standards (i.e. hemoclips or thermo-coagulation with or without pre-injection with diluted epinephrine) in hemostatic treatment in patients with acute upper gastrointestinal bleeding from non-variceal causes. The non-inferiority primary endpoint is control of bleeding over 30 days from randomization. Other outcome endpoints include further endoscopic, angiographic or surgical treatments, hospitalization, blood transfusion and mortality. Investigators also compare ease of therapy measured by procedure time and a 10 cm visual analogue scale rated by endoscopists. Endoscopic application of TC-325 is a simple and less skill dependent technique. It may prove useful in bleeding from anatomically challenging sites of the gastro-duodenal tract.

Postpartum hemorrhage (PPH) is responsible for around 25% of maternal mortality worldwide reaching as high as 60% in some countries.PPH can also be a cause of long-term severe morbidity, and approximately 12% of women who survive PPH will have severe anemia. Postpartum hemorrhage has been defined as blood loss in excess of 500 ml in a vaginal birth and in excess of 1 L in a cesarean delivery.For clinical purposes, any blood loss that has the potential to produce hemodynamic instability should be considered a PPH. However, clinical estimates of blood loss are often inaccurate. Primary (immediate) PPH occurs within the first 24 hours after delivery and approximately 70% of these cases are due to uterine atony. Furthermore, uterine tony is defined as the failure of the uterus to contract adequately after the child is born. Guidelines for the management of postpartum hemorrhage (PPH) involve a stepwise approach including the exclusion of retained products of conception and genital tract trauma. Uterine atony, which is the most common cause, the management of uterine atony is an established stepwise protocol that in many international guidelines. Uterine massage is recommended for the treatment of PPH. Initiate uterine massages soon as excessive bleeding/uterine atony is identified. Intravenous oxytocin alone still is the recommended uterotonic drug for the treatment of PPH. If intravenous oxytocin is unavailable or if the bleeding does not respond to oxytocin, intravenous ergometrine, oxytocin-ergometrine fixed dose or a prostaglandin drug (including sublingual misoprostol, 600 mcg) should be given. The use of intrauterine balloon tamponade is recommended for the treatment of primary PPH due to uterine atony in women who do not respond to uterotonics or if uterotonics are not available. Since 1983, when Goldrath published evidence that inserting a Foley catheter in the uterus and inflating it with water could achieve tamponade, case series and other studies have suggested that various uterine balloon tamponade(UBT) devices may be effective in treating PPH. The studies used various types of UBT devices, including a condom catheter, a Foley catheter, the Sengstaken-Blakemore Esophageal Tube, the Rusch Balloon, and the Bakri Uterine Balloon. In 2007, a systematic review of treatment options for PPH found that 84% success rate of UBT does not significantly vary from surgical treatment outcomes.The World Health Organization (WHO), the International Federation of Gynecology and Obstetrics (FIGO), the American College of Obstetricians and Gynecologists(ACOG), the Royal College of Obstetricians and Gynecologists(RCOG), and the International Confederation of Midwives (ICM) recognize balloon tamponade as a method that could significantly improve the management intractable PPH, especially in low-resource areas. In 2012, WHO updated the guidelines for the management of PPH and retained placenta to include: "The use of intrauterine balloon tamponade is recommended for the treatment of PPH due to uterine atony. This recommendation is now stronger than the previous guidelines. It can be used for women who do not respond to uterotonics or if uterotonics are not available. This procedure potentially can avoid surgery and is appropriate while awaiting transfer to a higher-level facility".Furthermore, FIGO included UBT as a recommended second-line intervention for the treatment of PPH in their updated guidelines issued in 2012. Bakri first published the concept of intrauterine balloon technology in the management of hemorrhage secondary to placenta praevia-accreta during caesarean section with or without bilateral hypo gastric arterial ligation.In 2006, the ACOG Practice Bulletin, published by the American College of Obstetricians and Gynecologists, made mention of the Bakri postpartum balloon for its specifically tailored design that enables conservative management of uterine bleeding in cases of uterine atony and other causes of PPH. The idea of using a condom as a balloon tamponade was first generated and evaluated in Bangladesh by Sayeba Akhter to fill a need and in response to the high cost of commercially available UBT devices.

The purpose of this study is to evaluate the impact of early intrauterine tamponade with a Belfort-Dildy balloon catheter in immediate postpartum hemorrhage(IPPH) after vaginal delivery and refractory to first-line uterotonic treatment, ie performed at the same time as second line uterotonic treatment, as compared tolate intrauterine tamponade performed in case of failure of second line uterotonic treatment, on the final severity of PPH. ).

The purpose of this study is to see how much gabapentin will reduce headaches associated with subarachnoid hemorrhage (SAH) and to reduce the amount of narcotic pain medication prescribed.

PostPartum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most commonly used uterotonic drug to prevent and treat PPH in North America. However oxytocin has a very short duration of action, requiring a continuous infusion to achieve sustained uterotonic activity. Moreover large doses are associated with adverse effects like hypotension, nausea, vomiting, dysrhythmias and ST changes. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recommended a single dose of 100 mcg of carbetocin at elective cesarean delivery to promote uterine contraction. In three studies recently performed at Mount Sinai Hospital, the investigators have found no difference in uterine contractility between the doses of 20- 120 mcg carbetocin and that the ED90 is 14.8 mcg. Thus a larger trial comparing the minimum effective dose determined in the previous three trials with the standard 100 mcg dose is necessary to confirm these findings.

There is a marked lack of evidence on the optimal prevention of ischaemic stroke in patients with atrial fibrillation and a recent intracerebral haemorrhage (ICH) during treatment with oral anticoagulation. These patients are currently treated with vitamin K antagonists, DOACs, antiplatelet drugs, or no antithrombotic treatment, depending on personal and institutional preferences. Treatment with a direct oral anticoagulant like apixaban might be an attractive alternative in terms of a low risk of recurrent ICH, while at the same time being effective for the prevention of ischaemic stroke. This study aims to obtain reliable estimates of the rates of vascular death or non-fatal stroke in patients with atrial fibrillation and a recent anticoagulation-associated intracerebral haemorrhage who are treated with apixaban versus those who are treated with antiplatelet drugs or no antithrombotic drug at all. This study has a multi-centre, phase II, randomised, open-label clinical trial with blinded outcome assessment design.
