Active clinical trials for "Hemorrhage"

Postpartum hemorrhage is the leading cause of maternal, uterine atony accounts for 75-90% of primary postpartum hemorrhage. The efficacy of the Uterine compression suture in the treatment of atonic postpartum hemorrhage is time-tested and can be said to be almost established .The aim of this study was to assess the role of the Mansoura-VV uterine compression suture as an early intervention in the management of primary atonic postpartum hemorrhage.

Rationale: Approximately 10% of neonates admitted to neonatal intensive care units develop a major hemorrhage. In an attempt to avert this severe complication various preventive measures have been implemented. One of these is the transfusion of platelets to premature neonates with low platelet counts. However, this practice is not supported by scientific evidence. Most neonates with low platelet counts never experience a major bleeding and platelet transfusions may carry risks of volume overload or infection. Therefore, it is important to treat only those patients that truly benefit from this intervention. We urgently need a scientifically based tool to predict which premature neonates are at risk for major bleeding. A few prediction models do exist, but these only allow assessment of bleeding risk at baseline, and do not correct for changes in clinical status during the admission period. We believe that adding this feature to our prediction model will significantly improve our ability to predict bleeding. The prediction model will also be helpful in developing individualized transfusion guidelines as it helps us to predict which neonates would benefit from prophylactic platelet transfusions. Main objective: to develop a dynamic prediction model for bleeding in preterm neonates with low platelet counts. Study design: retrospective observational cohort study. Study population: neonates with a gestational age at birth of < 34 weeks admitted to a neonatal intensive care unit (NICU), with a thrombocyte count of less than 50x109/L will be included. Assessments: only data generated through standard care will be collected. This includes platelet counts, cerebral ultrasounds, information about bleeding and transfusions, and multiple clinical variables. Main study endpoint: major bleeding during admission Statistical analyses: dynamic prediction model using landmarking.

This study investigate associations between mild hypothermia (patients' core temperature ≤ 36.0 degrees Celsius) and intra-operative blood loss and surgical site infections (SSI) in patients undergoing major abdominal surgery.

To compare the two administration methods of tranexamic acid for patients undergoing the first unilateral THA, to explore the effects of tranexamic acid on perioperative blood loss from the aspects of dominant blood loss, hidden blood loss, blood transfusion rate, mean blood transfusion volume and safety so as to further clarify what kind of medication is more effective.

Anti-Mullerian hormone (AMH) is a marker for ovarian reserve. There are many studies about AMH changes in ovarian surgery, but little is known for other surgeries. We seek to investigate the hormone variations before and after uterine artey ligation for postpartum hemorrage (PPH)

This clinical trial is a retrospective single-centre study. Research data will be acquired via patient histories stored in the hospital data system. Data of patients who received a Transjugular Intrahepatic Portosystemic Shunt (TIPS) at the University Hospital Graz between 1.1.2004 and 31.12.2017 will be included into the study. The aim is to investigate the outcome (transplantation free survival, time to (re)occurrence of ascites, occurrence of hepatic encephalopathy) of patients with portal hypertension after TIPS.

Post sphinterotomy-bleeding (PSB) occurs in 1-2 % of Endosocpic Retrograde Cholangiopancreaticography (ERCP) and usually needs no blood transfusion after endoscopic therapy but can be life-threatening in some rare cases. There are no prospective comparative studies concerning the endoscopic treatment of PSB due to the rarity of the incident. Insertion of an endoprosthesis in the common bile duct may be more effective than Epinephrin-injection into the papilla which is the therapy of first choice. A retrospective single centre analysis on both used methods over a study period of 16 years shall be performed.

Bladder cancer is one of the most common cancers of the genitourinary tract in adults, and its incidence distinctly increases with age . In almost two-thirds of cases, the disease is superficial at presentation and involves the mucosal and sub mucosal layers or the lamina propria of the bladder, whereas ∼20% to 30% of patients have muscle-invasive tumors. Superficial bladder cancer is treated by transurethral endoscopic resection, which can be followed by endovesical therapy for patients at risk of disease recurrence and progression . In contrast, muscle-invasive bladder cancer is generally treated by radical cystectomy with pelvic lymph node dissection and then creation of urinary diversion to create an alternate route for urine passage, which demonstrates 10-year recurrence-free survival rates of 50% to 59% and overall survival rates of ∼45% . These major surgeries have a prolonged operative times and are associated with significant risk of complications including high risk of perioperative bleeding and subsequent need for blood transfusion with significant postoperative complications, which are reportedly in the range of 24% to 64% .

In the present study will be compared Carbetocin with ergometrin in the prevention of postpartum haemorrhage (PPH) in parturients that are undergoing caesarean section and are not presenting risk factors for PPH. As indicators will be used intraoperative blood loss, as well as the value of hemoglobin and hematocrit 24 hours after the caesarian section.

We are attempting to improve the cerebral monitoring of extremely low gestational age (ELGA) infants, such that in the future, real-time monitoring will be possible, to aid clinicians in their management of these infants. We wish to establish a new NIRS device, diffuse correlation spectroscopy (DCS), as a safe, noninvasive and informative bedside tool for assessing and monitoring brain health in ELGA infants during the first few days of life. It is hoped that this method will provide detailed information on changes in oxygen consumption and metabolism, and cerebral perfusion. This technique will have wide applicability, but for this research study we wish to focus on the effect of blood flow instabilities, intermittent hypotension and hypoxic episodes, pressure passive CBF periods, and hypoperfusion on the preterm brain during the first days of life, and their relationship with incidence of intraventricular hemorrhage (IVH). We aim to recruit 100 premature infants to obtain data to: Test the feasibility of NIRS-DCS to monitor cerebral activity, perfusion and oxygen consumption in extremely premature infants during the first week of life. To assess if these baseline values are impacted by intermittent hypoxic episodes. To assess if cerebral blood flow disturbances correlate with incidence of intraventricular hemorrhage. Correlate the NIRS-DCS findings with clinical outcome at hospital discharge.
