Filter by:Randomized clinical trial , with a sample of 60 children with atypical swallowing, class II and with SN1 orthopedic appliances these patients were randomly divided into, group 1: 30 patients with SN1 orthopedic appliances and myofunctional therapy and group 2: 30 patients with SN1 orthopedic appliances and without myofunctional therapy.
Our study focuses on reducing the use of CT (Computer Tomography) for pedicle screw instrumentation, replacing CT with X-ray. We are writing a program to measure the position on X-ray seeing whether the position meets that on CT after operation. In the future,our method can be used in fluoroscopy, helping us detecting screw malposition efficiently during the surgeries, and hoping reduce complications.
In this study, investigators will demonstrate and prove a ellipse method (Liaw's version) for measurement and detection of acetabulum cup retroversion.
This study mainly measures the orientation of acetabulum cup post total hip arthroplasty. Using "Liaw's Version", a new and accurate standardization method, investigators are trying to analyze acetabulum cup anterversion change postoperatively.
Study hypothesis: The Cardiotronic ICON non-invasive cardiac output monitor gives accurate information when placed on a patient's Right or Left side. Summary: To simultaneously compare physiologic data collected from two non-invasive cardiac output monitors placed bilaterally on pediatric patients undergoing general anesthesia. The FDA approved Cardiotronic ICON non-invasive cardiac output monitor has been validated by the manufacturer in pediatric and adult patients with leads placed on the left side. However, sometimes the surgical site and/or patient position precludes placement of the monitor leads on the left side. In such situations it would be useful to know whether placement of the monitor's leads on a patient's right side gives accurate cardiac output data. We will prospectively collect, and compare, simultaneous physiologic data for all enrolled children using two monitors, one on the patient's right side and one on the patient's left side.
