Project # 1 title: Endo Pharmaceuticals - An Open-Label, Ascending, Two-part, Single and Multiple-Dose evaluation of the Safety, Pharmacokinetics, and Effectiveness of Oxymorphone for Acute Postoperative Pain in Pediatric Subjects: EN3203-010
Human subjects IRB approved project number: 102008-028

Project Type
Patient-based research

Brief Description of Project:
Oxymorphone hydrochloride is a semisynthetic opioid agonist derived from thebaine with more rapid onset of action and a significantly higher analgesic potency compared to the structurally-related compound morphine. Oxymorphone was first synthesized and developed in the 1950s and oxymorphone-containing products were first approved by the FDA in 1959. Up to now it was not evaluated in pediatric patients.

This study is evaluating the safety, pharmacokinetics and effectiveness of oxymorphone for acute postoperative pain in pediatric subjects. We plan to enroll a total of 15 subjects in our center.
The student will participate in the subject selection, enrollment and consent procedures and postoperatively will assist in evaluation of pain, PKA blood sample collection and data recording.

Project # 2 title: Changes in Intraocular Pressure during Surgery in Prone Position in Pediatric Patients

Human subjects IRB approved project number (where applicable): 012008-067

Project Type - Patient-based research

Brief Description of Project:

This is a full board review, active study in which we are recording the eye pressures a minimum of 4 instances intraoperatively during neurological surgery cases for prone position patients.
Vision loss or impairment after spine surgery is a devastating problem with an overall incidence variance in adult patients between 0.1 to 1 %. The incidence of vision loss or impairment in the postoperative period in the pediatric population is less prevalent than in adults and the exact numbers are unknown.
The IOP values and the magnitude of the IOP change over the duration of surgery in children operated in prone position have never been measured in pediatric patients. In consequence, we propose to determine time-dependent changes in IOP in children undergoing prone surgery. At the time we have 21 subjects enrolled and needing another 20.
The student will be involved in the identification of suitable subjects from the preoperative surgery lists, will participate in the consenting process and will help with data collection during neurosurgery. Finally, the student will be responsible with transferring the study data in the database.

Project #3 title: Multicenter Study of Use and Complication in Pediatric Regional Anesthesia

Human subjects IRB approved project number (where applicable): 062008-064

Project Type

Patient-based research

Brief Description of Project:
The aim of this study is to collect de-identified, prospective data on the use of regional anesthesia in pediatrics, to determine the incidence and nature of complications of these blocks and to develop benchmark data to allow institutions to compare their performance to an aggregate national standard. Our center is part of this national study which intends to enroll up to 50,000 prospective subjects (becoming the largest pediatric anesthesia study in US).
The student will be assisting the anesthesiologists performing the regional blocks with completing the data, performing follow-up in patients with continuous blocks (epidural blocks) and entering the data in the secure database.

Project #4 title: Use of Vein Viewer for Insertion of Peripheral Venous Cannula in Pediatric Patients with Difficult Intravenous Access

Human subjects IRB approved project number: 112008-041

Project Type Patient-based research

Brief Description of Project:
Even experienced clinicians fail to insert venous catheters in some patients. Failed cannulations are uncomfortable for patients, embarrassing for the clinician, and can delay needed medical treatments. We therefore are testing the hypothesis that use of Vein Viewer (a new device which utilizes near infrared light and patented technologies to illuminate subcutaneous vasculature by imaging their location on the surface of the skin) improves cannulation success rate and decreases the cannulation time.
The study is performed in conjunction with the intravenous nurse team at Children's.
The student will be following the IV nurse team, participate in the enrolling process by evaluating the inclusion/exclusion criteria, record the data and finally introduce the data in the database.

Project #5 title: Early clinical experience with the GlideScope Cobalt Video Baton in neonates and infants

Protocol is submitted for IRB approval.

Project Type
Patient-based research

Brief Description of Project:
The GlideScope video laryngoscope (Verathon Inc, Bothell, WA) is a new device for assisting intubation that is designed to allow a view of the glottis without the need for aligning the oral, pharyngeal, and tracheal axes.
This will be a clinical study looking into the ease and efficacy of the new GlideScope Cobalt Video Baton for intubation in neonates and infants. The laryngoscopy in all the consecutive cases presenting to the operating room at Children Medical Center for general anesthesia with endotracheal intubation, will be performed with the GlideScope Cobalt Video Baton. As outcome measurements, we will specifically measure the time to intubation, laryngoscopic views, number of attempts, and the success rate.
We intend to enroll 200 patients.
The student will be involved with patient enrollment, collecting the data and introducing it in the database.
