Filter by:First seconds after birth, new born baby go through physiologic changes to successfully adjust to the external environment specially establishment of independent respiration. Majority of the organ systems adaptation in newborns occur gradually, but radical and rapid cardiopulmonary adaptation must occur for neonates to survive. It is during this period that approximately 10% neonates require some level of support in the form of resuscitation. A knowledgeable, quick and skillful response by all caregivers is crucial for extra uterine survival. Tracheal intubation is performed frequently in the Neonatal Intensive Care Units (NICU) and delivery rooms. Neonatal intubation is a critical and time-sensitive procedure, and failure deprives the sickest newborns of oxygen. Current methods to detect a misplaced esophageal ETT in newborns are suboptimal. Physical examination findings are often unreliable, exhaled carbon-dioxide testing is often unavailable outside of resource-rich facilities and can lead to false positive results ,while chest radiographs are not only time consuming ,labor intensive but also expose vulnerable newborn babies to significant radiation However portable ultrasound machines are relatively available even in small centers mostly being used in the maternity units, being an indispensable tool for managing obstetrics, gynecology and trauma cases. POCUS methods of assessing ETT position offer an alternative that is time saving, cheap and safe, thereby of critical importance in the neonatal "time-is-brain" scenario. Our project aims to demonstrate that POCUS can effectively and accurately detect esophageal intubations, and in shorter period of time than current standard-of-care methods that are colorimetric end- tidal carbon-dioxide (CO2) detector and chest x-ray.
Introduction Undiagnosed deep vein thrombosis (DVT) can lead to significant morbidity and mortality, including death from DVT-associated massive pulmonary embolism (PE). While several validated clinical prediction rules, blood test and imaging modalities exist to investigate a potential DVT, there is currently a lack of rapid, accessible and reliable methods to exclude the possibility of DVT without resorting to formal venous duplex scanning. Currently, the use in the ED of a validated clinical prediction rule combined with high-sensitivity D-dimer test has a poor predictive value, as 75-90% of patients suspected of DVT have a negative formal venous duplex scan. Compression bedside ultrasound has however recently been shown to be a safe, rapid and accurate method for the diagnosis of proximal DVT in the emergency department with a high sensitivity and specificity (combined sensitivity and specificity of 96.1% and 96.8%, respectively1). Research Question In the present study, the investigators will primarily assess whether two-site compression POCUS combined with a negative age-adjusted D-dimer test can accurately rule out DVT in ED patients regardless of the Wells criteria. Methods This is a single-center, prospective, observational study carried out over one year in the Emergency Department of the Jewish General Hospital in Montreal, Quebec. The investigators aim to enroll a convenience sample of 475 patients aged 18 years and older presenting to the ED with symptoms suggestive of a DVT. All enrolled patients will receive the standard of care required for a lower leg DVT presentation. After calculating Patients DVT risk using modified wells criteria, all patients will undergo POCUS for DVT followed by a D-dimer test. Based on their results, patients will either undergo formal duplex scanning, or will be discharged without further testing and receive a three-month phone follow-up. A true negative lower leg DVT will be defined as follows: 1. Negative follow-up phone questionnaire for patients who were sent home with no formal duplex venous scanning. 2. Negative formal duplex venous scanning for patients who were deemed likely to have lower leg DVT using the Wells score, with a negative D-dimer and POCUS Age-adjusted DVT was added to account for below knee DVT and avoid the need for patients to return for fellow up duplex study in 1 week. To estimate our technique's sensitivity with a 4% margin of error with 95% confidence intervals, 92 confirmed DVT patients are needed. The investigators expect to recruit a total 475 patients within one-year period at the JGH (95 DVT-positive patients and 380 DVT-negative patients). Impact The use of compression bedside ultrasound with a negative age-adjusted D-dimer test to rule out DVT in the ED may accelerate the decision regarding patient disposition and significantly decrease the length of patient stay in the ED. In addition, it may help avoid unnecessary medical interventions and diagnostic tests, thus representing potential quality of care and cost-saving improvements as well.
PURPOSE: to evaluate the utility of bedside ultrasound performed by emergency physicians in the evaluation and reduction of colles fractures as compared with traditional pre and post reduction radiographs. With the objectives of assessing Emergency Ultrasounds (EU) utility in guiding reduction attempts of Colles fractures and to compare EU to x-ray for the final assessment of reduction adequacy.
This study is designed to determine if there is any relationship between performing an abdominal ultrasound on patients who present with hypotension and their clinical outcomes (as measured by 7, 30 day and discharge mortality).
