A Parallel-Group Randomized Controlled Trial Of The Boa®-Constricting Iv Band, Richard N. Bradley Dec 2015

A Parallel-Group Randomized Controlled Trial Of The Boa®-Constricting Iv Band, Richard N. Bradley

Richard N Bradley

Background. Few studies have demonstrated the ideal technique for placement of peripheral venous access.

Objectives. The purpose of this study was to conduct a randomized, controlled trial to determine if there was a difference in success rates for establishing peripheral intravenous lines (IVs) when using the BOA® Constricting Band (BOA) compared to a standard elastic tourniquet.

Methods. Eligible participants were paramedics working in the out-of-hospital setting and nurses working in a trauma center. The intervention group intended to use the BOA® for all IV attempts, while the control group intended to use standard elastic tourniquets. The primary outcome was success …


Collaborative Diagnosis: Interdisciplinary Problem-Solving Between Physicians And Lawyers, Robert Pettignano, Lisa Bliss, Sylvia Caley Nov 2015

Collaborative Diagnosis: Interdisciplinary Problem-Solving Between Physicians And Lawyers, Robert Pettignano, Lisa Bliss, Sylvia Caley

Patient and client-centered practice and accurate problem diagnosis require that we understand the context within which the patient/clients’ problem originated. Effective problem solving depends upon context-specific solutions. This article describes the interaction of a medical clinician/educator and two legal clinicians/educators who work and teach together as part of an interdisciplinary community collaboration. We demonstrate how a pediatric hospital and two medical schools that treat acutely and chronically ill children collaborate with a legal services clinic based in a law school to provide interdisciplinary clinical education for students and engage in interdisciplinary problem solving for the benefit of patients and clients. …


The Historical Evolution Of Endoscopy, Sarah Ellison Apr 2015

The Historical Evolution Of Endoscopy, Sarah Ellison

Honors Theses

INTRODUCTION: Minimally invasive surgery is on the rise and is becoming more common. Its advantage over traditional open surgery is a quicker recovery time and minimized risk of infection along with an aesthetically more pleasing smaller scar. Although many different scopes and instruments perform minimally invasive techniques, all minimally invasive instruments evolved from endoscopy. It wasn’t until the 20th century that they began to diverge to separate studies. Therefore endoscopy is considered in regards to instrument evolution. History is full of twists and turns as different pieces of the scope progressed so its advancement has been separated into the …

Visualizing the movement of angiocatheters during endovascular interventions is typically accomplished using x-ray fluoroscopy. There are many potential advantages to developing magnetic resonance imaging-based approaches that will allow three-dimensional imaging of the tissue/vasculature interface while monitoring other physiologically-relevant criteria, without exposing the patient or clinician team to ionizing radiation. Here we introduce a proof-of-concept development of a magnetic resonance imaging-guided catheter tracking method that utilizes hyperpolarized silicon particles. The increased signal of the silicon particles is generated via low-temperature, solid-state dynamic nuclear polarization, and the particles retain their enhanced signal for ≥40 minutes—allowing imaging experiments over extended time durations. The …
