A wide number of osteopathic techniques focusing on diaphragm have been proposed but, although systematically and efficiently used, there is a general lack of evidences able to clarify how and to which extent osteopathic manipulative treatment (OMT) on diaphragm is effective and determines a modification in muscles contractility and motion as well as an objective determination of the benefit on the patients receiving treatment. This study therefore aims at investigating whether, and how, a single session of selected osteopathic diaphragmatic techniques are able to affect muscle motility and thickness, assessed by ultrasounds, in a sample of healthy subjects and to compare results versus a group receiving a sham therapy and another one of non-treated subjects.
Central venous catheter placement is a common procedure in the intensive care unit and is a required skill for all residents working in the critical care setting. Central venous catheters (CVC) are placed for a variety of reasons including administration of caustic medications, administration of fluids or blood products for rapid resuscitation, access for hemodynamic monitoring or transvenous pacing, temporary vascular access for dialysis, or inability to obtain peripheral IV access. CVC's are routinely placed in the internal jugular vein in the Vanderbilt medical ICU and ultrasound guidance is used. Placement of the CVC on the right IJ instead of the left IJ is commonly preferred due to the more direct path to the superior vena cava. However, placement in the left IJ may be necessary for a variety of reasons. The investigators intend to compare the standard practice of residents and nurse practitioners placing IJ CVCs in the medical ICU against mandatory screening of the right and left IJ prior to selection of the CVC placement site. The investigators will accomplish this by assessing the relative first pass stick and overall success rates, the rate of aborted procedures, and the rate of complications between standard practice and mandatory screening of bilateral internal jugular veins prior to CVC site selection.
Investigators hypothesized that perioperative lung ultrasound would be beneficial in pediatric patients undergoing cardiac surgery compared to those who did not receive lung ultrasound.
This study explores the effect of a four-hour ultrasound course on physicians' point-of-care ultrasound performance on patients representing acute abdominal surgical conditions.
We aimed to verify the potencial role of bedside lung ultrasound findings of critically ill patients candidates to liberation from mechanical ventilation in predicting weaning outcomes. The analysis will be taken in two times: immediately before and at the and spontaneous breathing trial.
Previous studies have demonstrated that an experienced ultrasound operator is able to efficiently perform radial arterial puncture on patients where an initial operator failed to puncture arteries via simple palpation. The objective of this study is to compare "difficult-to-puncture" patients randomized into two groups: one group where ultrasound is used to aid artery localisation, and one group where only palpation is used.
This study will determine the efficacy of a teaching program incorporating hybrid simulation in training practicing anesthesiologists on ultrasound (US)-guided continuous peripheral nerve block (CPNB). This study will also examine the extent of practice change following participation in a regional anesthesia teaching program incorporating hybrid simulation. In addition, this study will assess remaining obstacles to incorporating the use of US-guided perineural catheters through identifying potential future interventions and "tool-kits" for setting up perineural catheter programs.
Patients with spondylarthritis (SpA) (including ankylosing spondylitis, psoriatic arthritis, arthritis as part of inflammatory bowel disease and reactive arthritis) have axial involvement (the spine) as well as peripheral inflammation in joints and entheses (where the tendons and ligaments are anchored to the bone). Patients with high disease activity of SpA may need biological treatment (anti-TNF alpha), which are very expensive medications. Thus it is necessary to have a sensitive method for assessing the response to treatment. Ultrasonography (US) is a validated and reliable method for assessing disease activity in joints and tendons, and may be used to follow the treatment response. The present study will include patients with SpA starting on anti-TNF alpha treatment (as first biologic medication or when switching to a new biologic treatment). The study is an extension of the ongoing NORDMARD study (Norwegian longitudinal observational study of arthritic patients starting disease-modifying treatment). The patients will be examined by use of US of 38 joints and 14 entheses at baseline and after 3, 6 and 12 months. The objectives are to explore US as a method to assess peripheral inflammatory activity for evaluation of response to medication as well as to compare the US pathology with clinical and laboratory findings.
The investigators aim to determine if ultrasound guidance results in improved technique when drawing blood via a radial artery puncture.
