Active clinical trials for "Hemorrhage"

This is a single blind, randomized, prospective study comparing SURGICEL Powder with SURGICEL Original (control arm) as an adjunct to achieve hemostasis in the control of capillary, venous, and small arterial hemorrhage when ligation or other conventional methods of control are impractical or ineffective during surgery (open, laparoscopic, or thoracoscopic) in Chinese adult subjects.

Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment). The primary objective of this study is to test the effect of 20% albumin on plasma volume expansion and fluid recruitment in the frame of blood loss replacement during cystectomy using established fluid kinetic models. The investigators expect that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin and be able to recruit fluid into the vascular compartment.

It is unknown whether different end-tidal carbon dioxide pressure levels have a clinically significant effect on bleeding and surgical field quality in septorhinoplasty, especially during controlled hypotension. Therefore, it was aimed to investigate the effect of ventilation strategy with controlled hypocapnia on intraoperative bleeding and surgical field quality for commonly practiced in septorhinoplasty.

Peptic ulcer bleeding is a common emergency for patients who need therapeutic endoscopy. According to international guidelines and Taiwan consensus, the standard therapy included proton pump inhibitor (PPI) and endoscopic therapy. For high-risk peptic ulcers, such as active spurting, oozing bleeding, a nonbleeding visible vessel or ulcers with adherent clots, we apply endoscopic hemostasis with epinephrine injection in combination with either heater probe coagulation, hemoclipping and/or rubber band ligation. Parenteral high-dose PPI is administered after endoscopic hemostasis. Though current standard endoscopic therapy plus PPI infusion are highly effective, 5%-10% of the patients still experience recurrence of bleeding after the initial treatment. It is still an important issue to reduce recurrent peptic ulcer bleeding after standard endoscopic therapy. Tranexamic acid reduces bleeding by inhibiting clot breakdown by inhibiting the degradation of fibrin by plasmin. It is effective to be used topically to reduce bleeding during surgery. However, the effect of application of tranexamic acid orally or intravenously for gastrointestinal bleeding was still controversial, probably because that the route of tranexamic acid use is not precise at the bleeding site. Tranexamic acid has anti-fibrinolytic effects at the bleeding site, so it is possible that use of tranexamic acid locally may have better efficacy than via intravenous or oral route. We propose to investigate the effectiveness and safety when using tranexamic acid locally under endoscopic guidance in patients with peptic ulcer bleeding after standard endoscopic therapy.

Prophylactic tranexamic acid has shown been shown to reduce maternal mortality from postpartum hemorrhage with no adverse effects, but has not been studied to reduce bleeding complications with dilation and evacuation (D&E). We propose a randomized, double-blinded, placebo-controlled pilot study to determine whether routine use of intravenous (IV) tranexamic acid will decrease the need for interventions to control bleeding at the time of D&E at 16 to 24 weeks gestation.

Postpartum hemorrhage continues to be the leading cause of maternal morbidity and mortality worldwide. Successful management of postpartum hemorrhage requires not only administration of the right medicine, but also a rapid and coordinated response from a multi-professional team. A prerequisite for this is that the individuals are well trained, which the investigators believe can be improved by video debriefing of real-life events. The purpose of this study is to improve obstetric teams management of postpartum hemorrhage using video recordings of real-life events in post event debriefings. Cameras are placed in the ceiling of all delivery rooms to record obstetric teams' management of postpartum hemorrhage. Video recording requires informed consent from all participants. After an event, the team will review their own performance on video in a debriefing session to improve future performance.

To evaluate the safety and effectiveness of the Lava LES for the embolic treatment of arterial hemorrhage in the peripheral vasculature.

Fluid intravascular replacement is usually performed with either balanced crystalloids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids, and albumin solutions have been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. The mobilization of extravascular fluid by infusing a hyper-oncotic solution like 20% albumin solution has been shown, causing endogenous fluid recruitment and blood volume expansion. The primary objective of this study is to compare the effect on plasma volume expansion and fluid recruitment of 3 different types of fluids (Albumin 5% and Albumin 20% and Ringer-lactate) during the hemorrhagic phase of the cystectomy procedure. Secondary objectives are the assessment of the hemodynamic parameters during surgery and the follow-up of pro-ANP and pro-BNP peptides. Glycocalyx proteins will be followed to evaluate endothelial wall shedding and microcirculation damages.
