Filter by:This is a study of patients admitted with major traumatic injuries. Such patients may develop inadequate circulation to the organs as a result of internal blood loss. Early detection of internal blood loss can be difficult as physical examination alone may miss patients with significant blood loss. Some patients with internal bleeding will arrive with low blood pressure; these patients are usually given 2 liters of intravenous fluid to determine if their blood pressure will recover. If the blood pressure does not rise or if it drops again later, the blood loss can be assumed to be severe, and the patient will likely need transfusions, surgery and other interventions. However, this fluid treatment method can lead to delays and complications as some patients may initially respond but then continue to bleed. The inferior vena cava (IVC) is the large vein draining blood from the lower body to the heart. The inferior vena cava is known to empty when the patient has had significant blood loss. The vena cava diameter can be seen using ultrasound. This study intends to perform ultrasound to examine the vena cava diameter on patients just after arriving with major trauma. The hypothesis of the proposed study is that an ultrasound assessment protocol of inferior vena cava diameter and collapsibility can detect and aid management of non-compressible hemorrhage in major trauma victims. After the patient has been given the 2 liter intravenous fluid treatment, the inferior vena cava diameter will be measured again. A third examination 8-24 hours after admission will determine if the inferior vena cava diameter has returned to normal. We propose that measuring the inferior vena cava in this manner can predict those patients who are likely to continue bleeding and require interventions such as surgery. Early detection in these patients may avoid delays in treatment, complications and excess mortality. Because this examination is done with handheld ultrasound machines, it could be done outside hospitals and in military combat casualty care.
This research study seeks to explore the effects of massage techniques on pain and anxiety relief among patients with subarachnoid hemorrhages in the ICU setting in comparison to subarachnoid hemorrhagic patients using standard medical therapy. In addition, our aim is to decrease the overall medication use to treat pain and anxiety, and to determine the impact of massage on sleep duration, quality, and breathing. Our goal is to improve and promote comfort during the ICU stay as well as decrease the need for narcotic medication usage.
Up to now, only data about early and single coagulation screening exist in extreme low birth weight infants (ELBW) infants. In neonatal practice, coagulation abnormality in preterm babies is primarily investigated by measuring prothrombin time (PT). In fact, FVII activity, which is an important determinant of PT, is strongly associated with bleeding risk. Thus, a method to measure PT with small volume samples (10μL) provides the possibility for serial monitoring even in ELBW infants (CoaguChek®XS, Roche Diagnostics, Vienna, Austria)). Substitution of fesh frozen plasma seemed beneficial in ELBW infants and first trials with rFVII revealed promising results in this patient population. Thus, coagulation monitoring might lead to early and adequate therapy and therefore to a better outcome. The investigators hypothesize that ELBW infants (<1000g birth weight) with primary severe prolongation of prothrombin time or development of severe prothrombin prolongation during sequential monitoring may have more frequent and more severe bleeding incidents (Intraventricular haemorrhage and pulmonary haemorrhage). The investigators aim to explore whether monitoring of PT can predict bleeding events in ELBW children.
This study is determining the clinical outcomes, based on neurological testing, for the parafascicular minimally invasive clot evacuation technique. We will collect data from the time of surgery up until 90 days post procedure. We will also be looking at financial data as well. - H(0): there is no economic benefit to the system with early surgical intervention for ICH - Alternative Hypothesis:H(1) Assuming clinical equipoise, i.e., no benefit in clinical outcome with early surgical intervention (null hypotheses) H(0) is correct), the ability to accelerate the patients care from the entry point to the exit point will result in a significant economic advantage to the system through cost reduction.
Normal human adult volunteers wereused to investigate the performance of medical devices intended to stop junctional bleeding on the battlefield.
After surgical procedures, interventions to reduce postoperative pain and bleeding are of great importance. In this study, the effect will be investigated of smearing common drugs, which are designed for injection, directly onto the raw wound surface (topical application) created during surgery. Topical application allows a small amount of drug to reach a large wound area, higher drug concentration in the exposed wound surface but very low concentration in the body, and no risk of injury from needles. Although beneficial effects of such an easy and low-cost intervention would be expected, the investigators have found no previous reports on blinded and controlled studies.
It is very important to decrease the bleeding during functional endoscopic sinus surgery (FESS) in order to increase the visibility of the surgical site. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on visibility of surgical site.
To investigate safety, tolerability, PK and PD of BI 655075 and to establish the BI 655075 dose(s) effective to reverse prolongation of blood coagulation time by dabigatran
This study is designed to validate implementation of the CRI algorithm in the CypherOx CRI system. Healthy human subjects will undergo progressive reduction in central blood volume to the point of hemodynamic instability (defined by a precipitous fall in systolic blood pressure (SBP) below 70 mmHg and/or voluntary subject termination due to discomfort (such as sweating, nausea, or dizziness) to validate the following hypotheses: The CypherOx CRI system will A. Trend intravascular volume changes (hemorrhage) B. Trend stroke volume changes and C. The CRI trend value is not relative to an initial CRI reading, instead it is an actual CRI trend value that does not require calibration or being placed during normal physiological conditions.
The investigators hypothesis in this study is that administration of rectal and sublingual misoprostol decreases intrapartum and postpartum haemorrhage.
