Using Collaborative Objective Simulation Clinical Evaluation With Undergraduate Nursing Students And Nurse Anesthesia Students Labor Epidural Placement In An Active Labor Patient, Chaka K. Jackson, Aisha Pierre

Doctoral Projects

Developing interdisciplinary teamwork and patient communication skills are essential for the student registered nurse anesthetist (SRNA) to provide quality patient care when administering epidural anesthesia. The synthesis of the evidence revealed limited available information on simulation use for SRNA epidural administration and collaboration. This doctoral project examined the effectiveness of learning through traditional simulation to enhance communication and collaboration between the Bachelor of Science in Nursing (BSN) and the Nurse Anesthesia Program (NAP) students. The BSN and NAP students were provided with a simulation environment to care for a laboring patient while improving patient safety and quality outcomes. The project …

Uniform Clinical Evaluation For Video Laryngoscopy In Nurse Anesthesia Training: A Policy Proposal, Kristen Yelverton

Doctoral Projects

At The University of Southern Mississippi’s (USM) Nurse Anesthesia Program (NAP), no standardized clinical evaluation for video laryngoscopy (VL) use exists. To address the gap in standardized evaluation of VL, an evidence-based, objective structured clinical examination (OSCE) will be developed and proposed to the USM NAP. The intervention to this need is the evaluation of the OSCE and supporting documents by the panel of experts. The aim of the OSCE would be to teach SRNAs in a step-by-step process how to properly handle a video laryngoscope and the necessary techniques to ensure both patient and student safety (Wunder et al., …

Randomised Controlled Trial To Assess The Effectiveness Of Apnoeic Oxygenation In Adults Using Low-Flow Or High-Flow Nasal Cannula With Head Side Elevation Versus Usual Care To Prevent Desaturation During Endotracheal Intubation In The Emergency Department (Apoxed): Study Protocol, Shahan Waheed, Nazir Najeeb Kapadia, Muhammad Faisal Khan, Salima Mansoor Kerai, Ahmed Raheem, Rubaba Naeem

Department of Emergency Medicine

Introduction: Apnoeic oxygenation is a process of delivering continuous oxygen through nasal cannula during direct laryngoscopy. The oxygen that is delivered through these nasal cannulas is either low flow or high flow. Although the effectiveness of apnoeic oxygenation has been shown through systematic reviews and randomised controlled trials, a comparison of high-flow versus low-flow oxygen delivery has not been tested through a superiority study design. In this study we propose to assess the effectiveness of giving low-flow oxygen with head side elevation versus high-flow oxygen with head side elevation against the usual practice of care in which no oxygen is …

Effective Number Theory: Counting The Identities Of A Quantum State, Ivan Horváth, Robert Mendris

Anesthesiology Faculty Publications

Quantum physics frequently involves a need to count the states, subspaces, measurement outcomes, and other elements of quantum dynamics. However, with quantum mechanics assigning probabilities to such objects, it is often desirable to work with the notion of a “total” that takes into account their varied relevance. For example, such an effective count of position states available to a lattice electron could characterize its localization properties. Similarly, the effective total of outcomes in the measurement step of a quantum computation relates to the efficiency of the quantum algorithm. Despite a broad need for effective counting, a well-founded prescription has not …

Blood Pressure Monitoring Following Individual Carpules Of Anesthetic Utilizing Computer-Controlled Anesthetic Delivery, Kristi M. Soileau, Adam E. Degenova, Qingzhao Yu

School of Dentistry Faculty Publications

To date, no study has evaluated blood pressure following administration of each carpule given for dental procedures using a computerized dental anesthesia system. Blood pressures taken prior to performing invasive periodontal procedures were compared with those readings measured following delivery of each of up to three consecutive carpules of Marcaine or Xylocaine in varying order. Pressure differences were also adjusted for age, sex, race, and whether a prescribed anxiolytic was taken beforehand. Neither systolic nor diastolic blood pressures changed significantly as compared to initial blood pressure readings. However, compared with Whites, Hispanics, and Middle Easterners, Blacks had significantly higher systolic …

BACKGROUND: Early ambulation after total hip arthroplasty predicts early discharge. Spinal anesthesia is preferred by many practices but can delay ambulation, especially with bupivacaine. Mepivacaine, an intermediate-acting local anesthetic, could enable earlier ambulation than bupivacaine. This study was designed to test the hypothesis that patients who received mepivacaine would ambulate earlier than those who received hyperbaric or isobaric bupivacaine for primary total hip arthroplasty.

METHODS: This randomized controlled trial included American Society of Anesthesiologists Physical Status I to III patients undergoing primary total hip arthroplasty. The patients were randomized 1:1:1 to 52.5 mg of mepivacaine, 11.25 mg of hyperbaric bupivacaine, …

Journal Articles: Anesthesiology

Extracellular vesicles (EVs) are a broad, heterogeneous class of membranous lipid-bilayer vesicles that facilitate intercellular communication throughout the body. As important carriers of various types of cargo, including proteins, lipids, DNA fragments, and a variety of small noncoding RNAs, including miRNAs, mRNAs, and siRNAs, EVs may play an important role in the development of addiction and other neurological pathologies, particularly those related to HIV. In this review, we summarize the findings of EV studies in the context of methamphetamine (METH), cocaine, nicotine, opioid, and alcohol use disorders, highlighting important EV cargoes that may contribute to addiction. Additionally, as HIV and …

Studies have shown successful analgesic outcomes of trigger point injections with local anesthetic for generalized myofascial pain.^1-2 This retrospective pilot study aimed to evaluate whether trigger point injections with bupivacaine decreases postsurgical pain compared with …

Nsaids For Analgesia In The Era Of Covid-19, Daniel L Herzberg, Harry P Sukumaran, Eugene R. Viscusi

Department of Anesthesiology Faculty Papers

Globally, non-steroidal anti-inflammatory drugs (NSAIDs) are highly used to treat pain. With the rise of the COVID-19 pandemic, the safety of NSAIDs use has been called into question. These concerns are worthy of review. At present, there is no compelling data showing that NSAIDs worsen the severity of COVID-19 symptoms or increase one's likelihood of contracting the illness. For patients in pain and without symptoms that could potentially be attributed to COVID-19 (cough, fevers/chills, lethargy, myalgias, anosmia and so on), NSAIDs should continue to remain a viable option to provide analgesia to patients in need.

Anaesthesiology, East Africa

Background: In low- and middle-income countries (LMICs) where echocardiography experts are in short supply, training non-cardiologists to perform Focused Cardiac Ultrasound (FoCUS) could minimise diagnostic delays in time-critical emergencies. Despite advocacy for FoCUS training however, opportunities in LMICs are limited, and the impact of existing curricula uncertain. The aim of this study was to assess the impact of FoCUS training based on the Focus Assessed Transthoracic Echocardiography (FATE) curriculum. Our primary objective was to assess knowledge gain. Secondary objectives were to evaluate novice FoCUS image quality, assess inter-rater agreement between expert and novice FoCUS and identify barriers to the establishment …

Frequency Of Intraoperative Hypotension After The Induction Of Anesthesia In Hypertensive Patients With Preoperative Angiotensin-Converting Enzyme Inhibitors, Fahad Salim, Fazal Hameed Khan, Muhammad Nasir, Rashid Ali, Ayesha Iqbal, Amir Raza

Department of Anaesthesia

Introduction: The renin-angiotensin-aldosterone system (RAAS) is an important target in the treatment of hypertension. Angiotensin-converting enzyme (ACE) inhibitors block the conversion of angiotensin I to angiotensin II. ACE inhibitors not only treat hypertension but also decrease morbidity and mortality in heart failure patients and in patients with acute myocardial infarction. The discontinuation of ACE inhibitors before the surgery is still controversial. To assess the current magnitude of the problem in our population, we aimed to conduct this study, which evaluated the frequency of intraoperative hypotension after the induction of anesthesia in controlled hypertensive patients with preoperative ACE inhibitors.
