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).

The Impact of Structured High Fidelity
Simulation on Anesthesia Ready Time


Primary Author: Michele Ballister,
DNP, CRNA

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.

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.

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.

Joseph_OSullivanComparative Resuscitation Measures for the Treatment of Desipramine Overdose

Primary Author: Joseph O’Sullivan, CRNA, PhD
Coauthors: Arthur Johnson, RN, PhD; Melissa Waterman, CRNA, MSN

A toxic dose of desipramine (tricyclic anti-depressant) causes cardiac arrhythmias and ultimately asystole. Resuscitation in the emergency room is difficult and almost always unsuccessful. Anecdotal evidence suggests that an infusion of lipid emulsion may be an effective treatment. The purpose of this study was to determine the optimal combination of lipid rescue and traditional ACLS therapy for the treatment of desipramine overdose using a porcine model. The results indicated that the groups that received vasopressin were more likely to survive than those that did not vasopressin and the groups that received lipid emulsion were more likely to survive than those that did not receive lipid emulsion.
