Type II Diabetes Mellitus: Amy Reed
Relationships Between Preoperative
Physiologic Stress, Gastric Content
Volume and Quality and the Risk of
Pulmonary Aspiration

Primary Author:
Amy Reed, PhD, CRNA

Pulmonary aspiration is a potentially fatal anesthetic complication occurring when gastric contents enter the respiratory system. Current fasting guidelines aim to decrease the risk of pulmonary aspiration; however, these guidelines are for healthy individuals and fail to account for type II diabetes mellitus (DM II) patients (ASA, 2011).

Incidence and Risk Factors of Kelsey Nelson
Gastric-to-Pulmonary Aspiration
in Patients Undergoing Elective
Upper Gastrointestinal Endoscopy

Primary Author:
Kelsey Nelsen, BSN, RN, PHN

Amy Gnagey, APRN, CRNA, DNAP

Oludare Olatoye, MD
Rochelle Molitor, MD
Nathan Smischney, MD
and Adam Jacob, MD

Gastric-to-pulmonary aspiration is a recognized risk during upper gastrointestinal endoscopy. The risk of aspiration is suspected to be significant in this population due to manipulation of the oropharynx and underlying gastrointestinal pathologies, but a thorough assessment of this risk is lacking.

The Effect of Data-Entry TemplateBryan Wilbanks November 2018
Design and Anesthesia Provider
Workload on Documentation Accuracy,
Documentation Efficiency, and User-

Primary Author: Bryan Anthony Wilbanks,

This study used observational data collection and psychometric instruments (for perceived workload and user satisfaction) at three hospitals that each used different methods of data-entry for perioperative documentation (auto-filling with unstructured data, computerassisted data selection with semi-structured documentation, and paper-based documentation).

Development of a Training Program in Aaron Ostrowski July 2018
Peripherally Inserted Central Catheter
Placement for Certified Registered
Nurse Anesthetists Utilizing an
N-of-1 Methodology

Primary Author:
Aaron Ostrowski, DNP, CRNA

Suzanne Morrison, DNP, CRNA
John O’Donnell, DrPH, CRNA

Patients were waiting an average of 23 hours for reliable, long-term central venous access in our hospital, and expansion of the IV team service was not an option. A training program in the insertion of peripherally inserted central catheters (PICCs) for CRNAs was developed to provide another cost-effective resource in our hospital to meet patients’ needs.

Perceptions of Acupuncture and Acupressure 
Amanda Faircloth March 2018by Anesthesia Providers: A Quantitative 
Descriptive Study

Primary Author: Amanda Faircloth, PhD,
Coauthors: Arkadiy Dubovoy, MD; Chuck Biddle, PhD, CRNA; Diane Dodd-McCue, DBA; and John F. Butterworth IV, MD

This study assessed U.S. anesthesia providers’ perceptions of acupuncture and acupressure. After institutional review board approval, 96 anesthesiology departments stratified by geographic region (Northeast, South, West, and Midwest) and institution type (university medical
centers, community hospitals, children’s hospitals, and veterans affairs hospitals) were selected for participation in an anonymous, pretested, online survey.

Student Registered Nurse Anesthetists: Michele Ballister September 2017
The Impact of Structured High Fidelity
Simulation on Anesthesia Ready Time

Primary Author: Michele Ballister,

Student registered nurse anesthetists (SRNAs) at a large academic medical center are limited in clinical training experiences due to the subjective observations of local anesthesia departments that SRNAs decrease OR efficiency because they require too much instruction. Utilizing the Iowa Model of Evidenced-Based Practice to Promote
Quality Care, the investigator inserted a six week structured simulation program into the nurse anesthesia curriculum prior to the SRNAs’ first clinical rotation.

Differential Expression of Jennifer Coyner July 2017
Phosphorylated Mitogen-Activated
protein kinase (pMAPK) in the lateral
amygdala of mice selectively bred
for high and low fear

Primary Authors:
LTC Jennifer Coyner, PhD, CRNA

Jennifer McGuire, PhD
Robert Ursano, MD, PhD
Clarissa Parker, PhD
Abraham Palmer, PhD
Luke R. Johnson, PhD

This research examines the cellular and molecular mechanisms that underlie conditioned fear learning in a mouse model of high and low fear. Individuals with posttraumatic stress disorder (PTSD) demonstrate a higher ‘fear load’ compared to individuals that do not have PTSD.

Patient safety and the delivery of quality care are major concerns for healthcare in the United States. Special populations (e.g., obese patients) need study in order to support patient safety, quantify risks, advance education for healthcare-workers, and establish healthcare policy.

Job Satisfaction, Burnout, andJoshua Lea September 2016
Turnover Intention Among Certified
Registered Nurse Anesthetists

Primary Author: Joshua Lea, MS, MBA, CRNA
Coauthors: Christine Brown-Mahoney, PhD; Irene Jillson, PhD

Certified Registered Nurse Anesthetists (CRNAs) are essential
members of the surgical team, and demand for them is increasing as the United States tries to control healthcare costs. Despite the economic benefits of employing CRNAs, like other highly trained healthcare professionals, CRNAs are difficult and expensive to replace.

Katherine_KiddeA Comparison of Epidural Strategies for Labor Analgesia 

Primary Author: LT Katherine Kidde, BSN
Coauthors: LT Meredith Tverdosi, BSN, CDR; Mark Lenart MD, CDR; Johnnie Holmes, PhD, CRNA

Epidural analgesia provides safe and effective analgesia with a reduced side effect profile along with increased maternal participation in labor. While the number of women utilizing epidural analgesia for labor continues to grow, there is still a lack of evidence to support which infusion strategy is the most effective. The purpose of this study is to compare the effectiveness of three epidural infusion strategies for labor analgesia to test the hypothesis that a lower basal rate with a higher patient controlled bolus will result in lower drug consumption than the other two comparison regimens.

Katherine_OjalvoThe Effect of Ultrasound Guidance and Vessel Transduction on Central Venous Catheter Placement Complications

Primary Author: Katherine Ojalvo, BSN, RN
Coauthors: Jennifer Cooley, BSN, RN; Karin Langford, BSN, RN

Based on recommendations from the National Institute of Health and Clinical Excellence, in 2011 Mayo Clinic Rochester instituted a policy mandating the use of ultrasounds for internal jugular central venous catheter placement in the operating room. In our study we compared rates of complications for central line insertion with and without ultrasound guidance between 2006 and 2012.

Tatjana_BevansPharmacokinetics and Analgestic Properties of Inhaled Remifentanyl

Primary Author: Tatjana Bevans, MSN, CRNA
Coauthors: Cassandra Rice, PhD; Derek Sakata MD; Chris Reilly, PhD      
Patients could benefit from an inhaled opioid for pain management in a clinical setting. We investigated the bioavailability and efficacy of inhaled remifentanil in rats. We concluded that rapid profound analgesia was achieved, and remifentanil and metabolites were measurable in rat blood following pulmonary exposure to remifentanil. 

Briana_MeserollThe Non-Compete Cause and the CRNA: An Assessment of Knowledge, Perception, and Experience 
Primary Author: Briana Meseroll, DNP, CRNA
Coauthors: Nathaniel Apatov, PhD, CRNA; Carolyn Rutledge, PhD, FNP

Mounting economic pressures and the challenge to maintain competitive advantage have resulted in many healthcare entities to require their practitioners to enter into restrictive covenants such as non-compete clause (NCCs). Many student nurse anesthetists and practicing certified registered nurse anesthetists (CRNAs) are unaware of the non-compete clause in employee contracts. CRNAs are often surprised by the implication of signing a non-compete clause could have on their future abilities to successfully advocate for themselves and their profession, in order to best meet the needs of the population they serve. This study was completed using an anonymous, Web-based questionnaire distributed to students and CRNAs nationwide and demonstrated a significant knowledge gap in the nurse anesthesia community surrounding the NCC.
