The Head Injury-associated Photosensitivity and Pupillary Function (HIPP) Study
Head InjuryTraumatic Brain Injury (TBI)2 moreAfter a head injury, many people find that exposure to light causes them increased discomfort. By measuring how the pupil in the eye constricts to flashes of red and blue light, this study will investigate whether this phenomenon is due to a change in the eye's sensitivity to light.
Inferior Vena cavaCollapsibility Index in Patients With Acute Kidney Injury
Acute Kidney InjuryThis is an observational study that will examine the possibility of determining the type of Acute Kidney Injury (AKI) using bedside ultrasound machines.
Anterior Segment Spectral-domain Optical Coherence Tomography in Patients With Closed Globe Injury...
Eye InjuriesThis study use anterior segment spectral-domain optical coherence tomography (SD-OCT) to exam patients with closed globe injury, and compared with slit lamp examination. The results showed that OCT can identify features of closed globe injury that were otherwise not visible on slit lamp biomicroscopy.
Emergent Expanded Access for ahSC Augmentation of Nerve Autografts After Severe Peripheral Nerve...
Sciatic Nerve InjuryThe primary purpose of this research study is to determine the safety of injecting ones own Schwann cells to augment sural nerve autografts after a severe, non-lacerating injury to the sciatic nerve has occurred.
Prehospital Resuscitation On Helicopter Study
Traumatic InjuriesThe Prehospital Resuscitation On Helicopter Study (PROHS) is a pragmatic, multicenter, prospective observational study of air ambulance-based prehospital resuscitation regimens currently utilized at the participating sites. Patients will be enrolled at participating sites that currently have blood products available on air ambulances and other sites that do not. This study will not change the current prehospital standard of care for resuscitation. The primary outcome will be in-hospital mortality and the primary unit of analysis will be the patient. Other outcomes of interest will include time to hemostasis, hospital length-of-stay, number of ventilator-free and ICU-free days, incidence of major surgical procedures, complications (transfusion-related acute lung injury [TRALI], acute kidney injury [AKI], multiple organ failure [MOF], acute respiratory distress syndrome [ARDS], sepsis, intra-abdominal complications, thromboembolic complications, compartment syndromes), lifesaving interventions, the amount and type of blood products and concentrates transfused (including prehospital), wastage of prehospital blood products and concentrates, use of external and internal hemostatic devices, and functional status at discharge/discharge destination.
Extracardiac Complications After Cardiac Surgery
Acute Lung InjurySepsis2 moreHypothesis of the study is that patients undergoing major cardiac surgery can develop extracardiac complications correlated to cardiopulmonary by pass.
Evaluation of Biomarkers of Traumatic Brain Injury
Traumatic Brain InjuryThe primary objective of this study is to evaluate the utility of the Banyan UCH-L1/GFAP Detection Assay as an aid in the evaluation of suspected traumatic brain injury (Glasgow Coma Scale score 9-15) in conjunction with other clinical information within 12 hours of injury to assist in determining the need for a CT scan of the head.
Imaging of Traumatic Brain Injury
Traumatic Brain InjuryThis project aims to study the prognostic ability of various MRI imaging markers in the evaluation of TBI patients. Cognitive, social, and occupational recovery will be measured at each time point, and compared to MRI findings. Healthy volunteers will serve as a comparison to the TBI patients. It is hypothesized that novel MRI markers of metabolism, hemodynamics, functional connectivity, and tissue microstructure will be related to the clinical status of the patient, as well as their social and occupational outcomes.
Scoring System for Inhalation Injury
Inhalation InjuryThe goal of this multicenter study is to develop a standardized scoring system for inhalation injury that can be used both to quantify and predict injury severity inhalation injury in adults over 18 years of age. A model will be developed based on clinical, radiographic, bronchoscopic, and biochemical parameters that will predict the severity of inhalation injury with greater than 80% predictive accuracy
Heart Rate Variability in Trauma Patients
TraumaThe purpose of this study is to develop new triage tool for trauma patients based on HRV. EKG will be prospectively measured in trauma patients in two locations: in the prehospital setting (the field and during transport by helicopter) and in the hospital setting. In each case HRV will be derived from the EKG signal, will be correlated with other non-invasive signals (e.g. near infrared spectroscopy (NIR), and bispectral EEG (BIS)), along with other routinely measured variables (blood pressure, respiratory rate, pulse oximetry, etc), will be correlated with injury severity and day of discharge. An algorithm will be constructed using multiple linear regression. The hypotheses are: reduced HRV in the field correlates with bad outcome; the specificity and efficiency of HRV as a screening tool can be improved by controlling factors such as heart rate, age, gender, respiratory rate, and pulse oxygen saturation; an easy to interpret HRV index can be derived that can be used for trauma triage or diagnosis.
