Filter by:Subarachnoid hemorrhage (SAH) is a frequent and severe disease. Mortality can reach 40%. The most frequent complication of SAH is arterial vasospasm, with estimated incidence as high as 70%. Vasospasm is responsible for cerebral ischemia leading to severe morbidity, poorer quality of life and increased mortality. Intravenous Milrinone, because of vasodilatory properties could be a therapeutic option. We hypothesize that intravenous infusion of Milrinone will improve the neurological recovery of patients with vasospasm following aneurysmal SAH at 3 months. This is a Phase III, multi-center, randomized, double-blinded, placebo-controlled study. The primary outcome will be the proportion of patients with a good outcome 3 months (defined as a modified rankin score ≤2).
Aneurysmal subarachnoid hemorrhage (aSAH) is a common type of acute hemorrhagic stroke. One of its complications, cerebral vasospasm (CVS), is the main cause of death and disability, with an incidence of up to 30%-90%. Blood and its metabolites are vital reasons for CVS. Normal saline, as an intraoperative irrigation fluid for the surgery of aneurysm clipping, can induce secondary damage to the brain. In this study, a new type of magnesium-rich artificial cerebrospinal fluid (MACSF) has been designed, which has similar ionic concentration, pH value and osmotic pressure compared with the physiological cerebrospinal fluid. It has been confirmed by animal experiments that MACSF can relieve the hyper-responsiveness of cerebral arteries to ET and 5-HT induced by hemorrhagic CSF from patients with aSAH by down-regulating the expression of ETA, contractile ETB and 5-HT1B receptors in the previous research. Therefore, MACSF may have potential effects on preventing and treating CVS. In this study, we plan to apply MACSF as an intraoperative irrigation fluid for the surgery of aneurysm clipping (MACSF group), which is compared with normal saline (historical control group). To evaluate the effects of MACSF on reducing the incidence of CVS and improving the clinical prognosis of patients with aSAH, the occurrence of CVS within 14 days after aneurysm clipping, NIHSS score, as well as mRS scores at 1, 3 and 6 months after aSAH will be recorded and compared. CVS related biomarkers will be used to evaluate the relationship between the occurrence of CVS and the levels of biomarkers in both CSF and blood samples from MACSF group.
The investigators studied the renal function index level in terlipressin treated cirrhotic patients with upper-gastrointestinal bleeding at different time point.
A retrospective, observational single centre study of electronic medical records of discharged patients who were admitted to from 1 January 2015 to 31 December 2018. Period of data collection was from 5 August 2019 to 15 September 2019.
A pilot trial for assessing early microvascular alterations after aneurysmal subarachnoid hemorrhage using dynamic 18F-FDG PET/CT. The primary endpoint will be the measure of early changes in cerebral glucose uptake reflecting microperfusion.
The study aims to compare the effect of addition of verapamil and Bisoprolol to general anasthesia aimed reduction in heart rate and blood loss during endoscopic sinus surgery.
Policies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds aLer birth, whereas latercord clamping usually involves clamping the umbilical cord greater than one minute after the birth or when cord pulsation has ceased
Prophylactic tranexamic acid will reduce blood loss during Caesarean section for placenta praevia
The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
This is a single-center randomized phase III clinical trial, the VWD-Woman Trial, in which 20 pregnant subjects with von Willebrand disease (VWD), defined as VWF ristocetin co-factor activity (VWF:RCo) <0.50 IU/ml (historic) and previous history of bleeding are enrolled. Subjects will include women with VWD age 18 years and older, excluding those who have a bleeding disorder other than VWD. Once enrolled, subjects who meet all of the inclusion and none of the exclusion criteria will be randomized to recombinant Von Willebrand factor (rVWF, Vonvendi ®) with Tranexamic Acid (TA, Cyclokapron®); or recombinant Von Willebrand factor (rVWF, Vonvendi®) alone to prevent postpartum hemorrhage after vaginal or caesarean delivery. The primary endpoint is quantitative blood loss (QBL) by a labor suite nurse at delivery. Secondary endpoints include safety assessment for postpartum lochial blood loss by Pictorial Blood Assessment Chart (PBAC), transfusion, blood products, thromboembolic events, and hysterectomy within 21 days; and mechanism of PPH reduction by VWF assays (VWF:RCo, VWF:Ag, VIII:C), fibrinogen, and d-dimer. Blood draws are at 5 time points, including at 36 weeks' gestation (screening), on admission for childbirth, and at 1 day, 2 days, and 21 days after delivery. The VWD-Woman Trial is considered greater than minimal risk as study drugs are given at delivery and special coagulation studies are obtained.
