Investigation Of Endotracheal Tube Versus Laryngeal Mask Airway Emergence Times For Surgical Patients., Samir M Patel, Rayyan Bhutta, Michelle Pershing, John Dillis, John O Elliott, Matthias J Franzen

OhioHealth Research Institute Articles

During surgical procedures requiring general anesthesia, an airway device is often placed to allow for adequate ventilation of the patient. Most commonly, endotracheal tubes (ETTs) or laryngeal mask airways (LMAs) are placed by the anesthesia provider. The difference between these two methods of ventilation is based on the location; ETTs pass through the glottis into the trachea, whereas the LMA sits above the glottis. This difference in placement may lend benefit to LMAs over ETTs, one of which includes a faster removal of the airway device. That is, after the surgical procedure is completed, there is a period when the …

Utility Of Readily Available Sugammadex For Emergent Neuromuscular Blockade Reversal., Theodore Renner, Kevin Varner, Austin Shaffer, Elizabeth Johnson-Gray, Noah Le, Matthias Franzen

Surgery Articles

INTRODUCTION: Anesthesia providers are often called upon to assist with other providers during can't intubate, can't ventilate (CICV) scenarios. The current availability of doses of sugammadex sufficient to provide emergent reversal of neuromuscular blockade in an operating room environment requires visits to multiple operating rooms at our institution. The Anesthesiology Department at OhioHealth Doctors Hospital sought to evaluate the practicality of administering a rescue dose of sugammadex (16 mg/kg) in a CICV scenario. The current storage of sugammadex is six 200 mg vials maximum per operating room, which would provide insufficient dosing for emergent reversal dosing for most adult patients. …

When The Right Ventricle Fails After Left Ventricular Assist Device Implantation: Prediction Tools, Recognition Strategies, And Support Options, Juan Jose Rodriguez Arias, James Schurr, Phyllis Billia, Joyce W. Wald

Journal of Shock and Hemodynamics

The incidence of right heart failure (RHF) during durable left ventricular assist device (LVAD) surgery ranges from 9% to 42%, depending on the definition. RHF can be divided into three peri-implantation categories: early acute, early, and late. Despite many available risk models, predicting RHF before durable LVAD implantation has been difficult. Preemptive right-sided temporary mechanical circulatory support can improve outcomes; however, if intraoperative RHF is not suspected, early recognition and appropriate intervention after surgery are important.

Using The Bispectral Index Monitor To Decrease The Incidence Of Unintended Intraoperative Awareness In The High-Risk Population, Bridget Hayes

Doctor of Nursing Practice Scholarly Projects

Unintended intraoperative awareness is a traumatizing complication of general anesthesia. This negative outcome affects 0.1-0.2% of all patients undergoing general anesthesia. Patients at higher risk for this experience include those undergoing emergency surgery, traumas, cesarian sections, those on cardiopulmonary bypass, those with substance use disorder, and those undergoing total-intravenous anesthesia (TIVA). This high-risk population is affected by unintended intraoperative awareness 1% of the time. The bispectral index (BIS) monitor has been proposed as a tool to decrease the incidence of unintended intraoperative awareness. There are several large, randomized controlled trials that demonstrate that using a BIS monitor decreases the incidence …

Implementation Of Guidelines For Preprocedural Ultrasound In Neuraxial Placement For Obstetric Patients With Scoliosis, Luther Nyirenda

Doctor of Nursing Practice Scholarly Projects

Neuraxial anesthesia including epidural, spinal, and combined spinal-epidural, is used with 65% of parturients in the United States for the management of pain and discomfort. Conventional landmark palpation has been the mainstay technique for neuraxial anesthesia, but unfamiliar spinal anatomy can lead to incomplete blockade or an increased incidence of complications. Scoliosis causes lateral curvature and rotation of the spine leading to arthritis and soft tissue changes that can present obscure anatomical landmarks, cause difficulty in needle passage, and result in inadequacy of local anesthetic efficacy. The literature illustrates that preprocedural ultrasound is recommended for needle placement in parturients with …

Volatile Anesthetic Exposure During Organogenesis (Weeks 6-9): Implications For Fetal Brain Development, Cheryce Daniel, Kylon Coombs

Rowan-Virtua Research Day

Organogenesis, particularly during gestational weeks 6 through 9, represent a critical window for fetal brain development. During this period, neurogenesis, neural tube closure and synaptic organization are actively occurring. Disruption of these processes, especially from exogenous agents, can result in lasting developmental consequences.

The U.S Food and Drug Administration has issued warnings regarding the use of anesthetic agents such as isoflurane, sevoflurane, and desflurane. Noting the potential risk of neurotoxic effects on the developing brain. This warning is particularly highlighted when administered drugs are present for long periods of time or during repeated procedures. The goal of this literature review …

Carbon Footprint Of Inhaled Anesthetics – Do The Risks Outweigh The Benefits?, Liam Kerrick, Joseph Moschella

Rowan-Virtua Research Day

Global warming presents many challenges to the healthcare system. Not only does the increasing global temperature have detrimental health effects itself, but the healthcare sector is also a huge contributor to global warming. One big contributor to global warming is the use of inhaled anesthetics, which possess global warming potentials up to 2,000 times greater than carbon dioxide. Recent proposals, such as a prospective ban of desflurane in 2026 by the European Commission, demonstrate the need to reevaluate many of the common practices within anesthesiology. This review looks to investigate the environmental impact, cost, and clinical efficacy of various anesthetic …

Decreasing Extubation Times Using Adaptive Support Ventilation: A Scoping Review, Daphne Thomas, Cole Vest, Luke Wilson, Shannon Witcher, Bobby Bellflower Dnsc, Nnp-Bc, Faanp

Doctor of Nursing Practice Projects

Purpose/Background:This scoping review explores the effectiveness of adaptive support ventilation (ASV) compared to conventional ventilation modes in reducing postoperative extubation times in adults undergoing general anesthesia with ventilatory support. Ventilator weaning is a critical determinant of recovery and outcomes in intensive care settings. ASV, a closed-loop ventilation mode, automatically adjusts ventilator parameters based on patient-specific respiratory mechanics and demand to optimize the weaning process. Although promising, evidence regarding ASV’s effectiveness remains inconsistent across different patient populations and surgical contexts.

Methods: A systematic literature search was conducted from August 2023 to December 2024 across PubMed, CINAHL, Medline, JAMA, and Google …

Diabetes Mellitus And Associated Vascular Disease: Pathogenesis, Complications, And Evolving Treatments, Kazi Islam, Rahib Islam, Ivan Nguyen, Hassan Malik, Humza Pirzadah, Barsha Shrestha, Isabella B. Lentz, Sahar Shekoohi, Alan D. Kaye

School of Medicine Faculty Publications

Diabetes mellitus is a metabolic disorder, characterized by elevated blood sugar levels (hyperglycemia) and insulin dysregulation. This disease is associated with morbidity and mortality, including significant potential vascular complications. High levels of hyperglycemia lead to not only elevated levels of reactive oxygen species but also advanced glycation end products, which are detrimental to the vascular endothelium and reduce protective compounds such as nitric oxide and prostacyclin. This damage contributes to the development of both macrovascular and microvascular complications. The present investigation explores the pathophysiological mechanisms of diabetic vascular complications and evaluates current management strategies, including lifestyle modifications, pharmacological treatments, and …

The Effect Of Abdominal Insufflation On Transversus Abdominis Plane (Tap) Block Efficacy In Laparoscopic Gynecologic Surgery, Hussein A. Bazzi, Justin Hruska M.D., Christopher Kliethermes M.D., Anne Thomas, Wael Saasouh M.D.

Medical Student Research Symposium

Introduction:

Approximately 15 million laparoscopic procedures are performed annually worldwide, with 4.8 million (32%) occurring in the United States. Laparoscopy is widely used for procedures such as bilateral tubal sterilizations, hysterectomies, and treatments for endometriosis and adhesions. During gynecologic laparoscopic surgeries, the abdomen is inflated with pressurized carbon dioxide for surgical visualization. Pain management typically involves a transversus abdominis plane (TAP) block, which provides intermediate postoperative pain relief (lasting 12–24 hours). This study evaluates the efficacy of TAP blocks performed during insufflation to improve postoperative pain outcomes compared to the traditional technique.

Methods:

This patient-blinded study included female gynecologic patients …

Advancing Provider Knowledge On Precedex Use To Prevent Postoperative Delirium Through Targeted Education, Brian Gibbs

Scholars Week

Postoperative delirium (POD) is a serious and multifactorial complication commonly affecting elderly surgical patients. POD is associated with increased morbidity, longer hospital stays, and higher mortality rates. The use of benzodiazepines and opioids during the perioperative period is a significant modifiable risk factor for POD. Despite the potential of Dexmedetomidine (Precedex) to reduce POD incidence due to its sedative, and analgesic properties, it is not widely available in many operating rooms (OR). This project aimed to educate anesthesia providers on the benefits of Precedex and its role in reducing POD in patients over 65 years old. A quality improvement project …

In critical illness, all elements of gut function are perturbed. Dysbiosis develops as the gut microbial community loses taxonomic diversity and new virulence factors appear. Intestinal permeability increases, allowing for translocation of bacteria and/or bacterial products. Epithelial function is altered at a cellular level and homeostasis of the epithelial monolayer is compromised by increased intestinal epithelial cell death and decreased proliferation. Gut immunity is impaired with simultaneous activation of maladaptive pro- and anti-inflammatory signals leading to both tissue damage and susceptibility to infections. Additionally, splanchnic vasoconstriction leads to decreased blood flow with local ischemic changes. Together, these interrelated elements of …

Anaesthesiology, East Africa

Approximately half of all antimicrobial prescriptions in intensive care units (ICUs) may be inappropriate, including those prescribed when not needed, in unnecessary combinations or for longer durations than needed. Inappropriate prescribing is costly, exposes patients to unnecessary side-effects and drives population-level antimicrobial resistance, the prevalence and consequences of which are greatest in low- and middle-income countries. However, the implementation of interventions to improve the appropriateness of antimicrobial prescribing has been variable and requires further study..
