Filter by:The main objectives are: - To establish the prevalence of major bleeding in patients treated with higher than recommended thromboprophylaxis doses. - To identify variables associated to higher risk of bleeding.
Hypothesis: Patients undergoing pars plana vitrectomy for the indication of diabetic vitreous hemorrhage will have a lower incidence of postoperative vitreous hemorrhaging during the 6-month trial period when vitreous substitution with 20-30% sulfur hexafluoride gas is utilized compared to vitreous substitution with balanced salt solution.
For patients with spontaneous subarachnoid haemorrhage, it remains to be investigated if there is an association between the time from patients call the Emergence Medical Coordination Center to neurosurgical admission and long-term outcome. This is a retrospective cohort study with four-year followup. The primary aim is to determine if the time to neurosurgical admission is associated to labour marked affiliation and mortality after four years.
Obstetric hemorrhage is one of the leading causes of maternal death worldwide. One of the challenges in management of hemorrhage is that young, healthy women compensate for blood loss via peripheral vasoconstriction, so they maintain their blood pressure and heart rate at normal levels even after experiencing significant blood loss. By the time vital sign abnormalities appear, interventions must be performed extremely rapidly to avoid organ damage and maternal death. Clinical methods of estimating blood loss in real time, such as visual estimation, are notoriously unreliable, and changes in laboratory testing such as hemoglobin levels lag hours behind actual blood loss. A tool which can detect and quantify blood loss in real time, before vital sign changes occur, has the potential to allow for earlier mobilization of resources and intervention in these cases, thus saving lives. This device is meant to detect changes in skin blood flow which reflect vasoconstriction. The investigators believe that this device, therefore, has the potential to be able to detect and quantify blood loss in real-time. However, as this novel device has never been used for this purpose, before undertaking a large clinical trial, the investigators feel it is necessary to perform a pilot study to assess the feasibility and tolerability of this device. The investigators plan to test this by asking 50 patients undergoing planned cesarean section to wear the device during their surgery. The device will collect skin perfusion measurements during the surgery, which will not be available to the operating team. The patients will also be asked to complete a survey regarding their experience wearing the device. The investigators will use this information to ensure that the device is transmitting interpretable data, that patients feel the device is tolerable during surgery, and to ensure that the device can be used in the operating room without any unforeseen logistical challenges which would need to be addressed in planning a larger trial. The investigators will perform a preliminary comparison of sensor readings to laboratory findings, to assist in planning a larger trial.
Out-of-hospital care during Chemical-Biological-Radiological-Nuclear-explosive (CBRNe) events have recently evolved, but the available knowledge is still extremely partial. In particular, the debate is still ongoing regarding which life-saving maneuvers should be implemented in the pre-decontamination phase while wearing CBRNe personal protective equipment (PPE). The investigators hypothesized that PPE may lengthen the execution times and worsen the success rate of invasive and non-invasive procedures. This trial involves residents in emergency medicine and anesthesia/critical care of the University of Padova (Italy) with the following procedures performed on high-fidelity manikins, after being divided into two groups (wearing and not wearing PPE): positioning of peripheral venous access; intraosseous access; drug preparation and administration; tension pneumothorax (PNX) needle decompression; tourniquet positioning; chest compressions. The primary outcome was the chest compressions depth mean difference between the two groups. As secondary outcomes, the investigators measured differences between the two groups in: the percentages of correct release during chest compressions; chest compressions rate (beats per minute); and the times needed to complete the above-mentioned procedures (other than chest compressions). The investigators expect that PPE will reduce CPR quality or delay the completion of the procedures.
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: 1. Test the feasibility of NIRS-DCS to monitor cerebral activity, perfusion and oxygen consumption in extremely premature infants during the first week of life. 2. To assess if these baseline values are impacted by intermittent hypoxic episodes. 3. To assess if cerebral blood flow disturbances correlate with incidence of intraventricular hemorrhage. 4. Correlate the NIRS-DCS findings with clinical outcome at hospital discharge.
Endoscopic treatment is recommended for initial hemostasis in nonvariceal upper gastrointestinal bleeding. However, the additional hemostatic efficacy of argon plasma coagulation (APC) has not been widely investigated. We designed a randomized trial comparing APC plus injection therapy vs hemoclipping plus injection therapy for peptic ulcer bleeding.
Unlike upper GI bleeding, for LGIB there is still a paucity of data on clinical presentation, patient characteristics, pathways of care and outcomes for LGIB patients. In-hospital mortality ranges from 1.2% to 8.8% (2-4), according to retrospective studies, but data from prospective series are still limited (5). Present multicentre, prospective, observational study was designed to explore these areas, to assess variations in practice management and to identify factors associated with patient outcomes.
Feasibility trial of the InPress Device to treat postpartum hemorrhage (PPH).
Fundoscopy, optical coherence tomography (OCT) and OCT-angiography (OCTA) are established examinations and bear minimal risks. The recognition of retinal microvascular signs will enhance the pathophysiological understanding of the vasculopathy in patients with intracerebral haemorrhage (ICH) and aneurysmatic subarachnoid hemorrhage (aSAH) and might serve as prognostic and diagnostic indicators.
