Thermoregulation In Colorectal Patients: Heating Co2 Insufflation Gas, Alejandro Conde, Alieu Jawara, Laura Savage, James Alberding Dnp, Michael Godbold

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

BACKGROUND: 600,000 colorectal surgeries are performed annually in the United States, with 26-90% experiencing some form of unintended hypothermia. Consequences of hypothermia include surgical site infections (SSIs), delayed wound healing, cardiac dysrhythmias, and increased hospital length of stay. Utilization of the laparoscopic approach to intra-abdominal colorectal surgery uses un-warmed CO₂ gas. Multiple studies demonstrate the addition of heated CO₂, for insufflation, reduces intraoperative hypothermia.

LOCAL PROBLEM: This project was implemented at a facility in Tennessee. On average, 250 laparoscopic colorectal cases are performed at this facility annually. Participants were adult colorectal surgical patients, 18 years …

Improving Patient Outcomes One Warm Patient At A Time, Lindsey King, Marcus Austin Robison, Julie Bonom Dnp, Michael Godbold Md

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

Patient Temperature measurement postoperatively reveals that hypothermia occurs in surgical patients 25-90% of the time. Unintended perioperative hypothermia can be linked to many negative patient outcomes such as increased incidence of surgical site infection (SSI), delayed wound healing and increased length of hospital stay, to mention a few. Any single or combination of the aforementioned issues can eventually lead to an increase in patient morbidity and mortality. The purpose of this proposed quality practice improvement project is to increase the compliance of hypothermia prevention strategies, specifically forced air warming, at the implementation site. The targeted practice improvement is aimed at …

Dynamic Simulation And Neuromuscular Control Of Movement: Applications For Predictive Simulations Of Balance Recovery, Misagh Mansouri Boroujeni

Doctoral Dissertations

Balance is among the most challenging tasks for patients with movement disorders. Study and treatment of these disorders could greatly benefit from combined software tools that offer better insights into neuromuscular biomechanics, and predictive capabilities for optimal surgical and rehabilitation treatment planning. A platform was created to combine musculoskeletal modeling, closed-loop forward dynamic simulation, optimization techniques, and neuromuscular control system design. Spinal (stretch-reflex) and supraspinal (operational space task-based) controllers were developed to test simulation-based hypotheses related to balance recovery and movement control. A corrective procedure (rectus femoris transfer surgery) was targeted for children experiencing stiff-knee gait and how this procedure …

Joint Reaction Force And Contributions Of Surrounding Muscles To Knee Joint Load During Stair Ascent In Total Knee Replacement Patients And Healthy Individuals, Robert Jacob Rasnick

Masters Theses

Total knee replacement (TKR) is commonly used to correct end stage knee osteoarthritis (OA) of the knee joint. Unfortunately, difficulty with stair climbing has been seen to exist, prolonging the challenges of TKR patents. Complete understanding of loading at the knee is of great interest in order to aid patient populations, implant manufacturers, rehabilitation, and future research. The outcome of a TKR is intended to reestablish normal motion and loading of the knee. Musculoskeletal modeling provides a means to accurately approximate joint loading and the corresponding muscle contributions during a movement.

The purpose of the present study was to examine …

Virtual Reality Aided Mobile C-Arm Positioning For Image-Guided Surgery, Zhenzhou Shao

Doctoral Dissertations

Image-guided surgery (IGS) is the minimally invasive procedure based on the pre-operative volume in conjunction with intra-operative X-ray images which are commonly captured by mobile C-arms for the confirmation of surgical outcomes. Although currently some commercial navigation systems are employed, one critical issue of such systems is the neglect regarding the radiation exposure to the patient and surgeons. In practice, when one surgical stage is finished, several X-ray images have to be acquired repeatedly by the mobile C-arm to obtain the desired image. Excessive radiation exposure may increase the risk of some complications. Therefore, it is necessary to develop a …
