Stability of Epinephrine in a Normal Saline Solution.

Objective: Dilution of concentrated epinephrine prior to intravenous use during clinical emergencies can delay urgent interventions. The objective of this study was to determine whether diluted epinephrine remains stable and sterile over time in common hospital settings.

Methods: Epinephrine samples were prepared by clinically relevant double dilution techniques.

Auto-Brewery Syndrome and General Anesthesia: A Case Report.

Auto-brewery syndrome (ABS) is a rare condition in which ethanol is endogenously fermented by fungi in the gut following a carbohydrate-rich meal, resulting in intoxication. We present a case of a patient with ABS successfully undergoing general anesthesia for symptomatic wisdom tooth extraction. During previous anesthetics, the patient had experienced postoperative nausea and vomiting (PONV) and awareness under anesthesia.

The Physical Compatibility of Glycopyrrolate and Rocuronium.

Objective: Scientific evidence has rarely, if at all, been reported in the literature demonstrating analytical confirmation of the physical compatibility and stability of glycopyrrolate and rocuronium combined. The purpose of this experiment was to determine if glycopyrrolate and rocuronium are physically compatible.

Methods: Glycopyrrolate and rocuronium were combined in various containers, observed over a 60-minute period, and compared against positive and negative controls.

Regulatory barriers to dental anesthesia services for special populations.

Aims: Sedation and general anesthesia are necessities for the treatment of many individuals within special populations such as those with physical and intellectual disabilities, fear/anxiety, or individuals requiring extensive procedures. This study aims to discover regulatory factors that may be contributing to the limited access to anesthesia services provided by dentist anesthesiologists.

Methods And Results: The study included an online survey completed by self-reported dentist anesthesiologists with 2 or more years of formal anesthesia training.

Medical Emergency Management in the Dental Office (MEMDO): A Pilot Study Assessing a Simulation-Based Training Curriculum for Dentists.

In the event of a medical emergency in the dental office, the dentist must be able to identify a patient in distress, assess the situation, and institute proper management. This study assessed the impact of a simulation-based medical emergency preparedness curriculum on a resident's ability to manage medical emergencies. This interventional and pre-post educational pilot study included 8 participants who completed a standard curriculum and 8 who completed a modified curriculum (N = 16).

Cardiac Arrest Upon Induction of General Anesthesia.

There are numerous causes of cardiac arrest in the perioperative period, including hypoxia, hypovolemia, and vagal response to medications or procedures during routine anesthetics. Initiation of adequate cardiopulmonary resuscitation, administration of epinephrine, and application of a defibrillator, with shocking when applicable, are all essential steps in achieving return of spontaneous circulation. Knowledge and utilization of monitoring equipment can alert the provider to problems leading to cardiac arrest as well as ensure proper resuscitative efforts during the event.

Pseudocholinesterase Deficiency Considerations: A Case Study.

Pseudocholinesterase deficiency, sometimes called butyrylcholinesterase deficiency, is a rare disorder in which the neuromuscular blocking drugs succinylcholine and mivacurium cannot be metabolized properly in the blood plasma. This disorder can either be acquired as a result of certain comorbidities or it can be inherited genetically. Anesthesia providers must understand the pathophysiology of pseudocholinesterase deficiency and be prepared to safely and effectively manage patients who show signs and symptoms consistent with the disorder after the use of the indicated neuromuscular blocking drugs.

Medical Management of Epiglottitis.

Epiglottitis is most commonly caused by bacterial infection resulting in inflammation and edema of the epiglottis and neighboring supraglottic structures. Acute infection was once found predominantly in children ages 2 to 6 years old, but with the introduction of the Haemophilus influenzae B (HiB) vaccine the incidence of cases in adults is increasing. Typical clinical presentation of epiglottitis includes fever and sore throat.

Malignant Hyperthermia: A Case Study in the Dental Ambulatory Surgery Setting.

Historically, patients who developed malignant hyperthermia had an extremely high rate of mortality. Today, if treated appropriately, patients who experience an episode of malignant hyperthermia will most likely survive. This dramatic decrease in mortality associated with malignant hyperthermia is due to several factors, including an increased understanding of the disease, improved diagnostic and monitoring equipment, and the development of lifesaving pharmacologic agents.

Ludwig's Angina: Anesthetic Management.

Ludwig's angina (LA) is a gangrenous cellulitis of the neck that spreads via continuity of the fascial planes. Treatment of LA includes aggressive antibiotic therapy as well as surgical drainage in many cases. The most common cause of infection is odontogenic and can be due to both aerobic and anaerobic bacteria.

Sugammadex: Efficacy and Practicality in the Dental Office.

Sugammadex is a novel drug capable of reversing paralysis induced by the common steroidal nondepolarizing neuromuscular blocking drugs, rocuronium and vecuronium. Reversal is complete at any depth of blockade dependent on the dose of sugammadex administered. This allows rocuronium to be used as a rescue agent in scenarios where succinylcholine is contraindicated.

Patients With Type 2 Diabetes: Anesthetic Management in the Ambulatory Setting: Part 2: Pharmacology and Guidelines for Perioperative Management.

Type 2 diabetes is a disease of metabolism in which the afflicted patient cannot properly utilize carbohydrates, fats, and proteins. Because the prevalence of type 2 diabetes is rapidly increasing throughout the general population, anesthesia providers must realize that a significant percentage of their patients will present with the disease. Anesthesia providers should have an intimate knowledge of the comorbidities and complications that are associated with type 2 diabetes and know the specific pharmacokinetics and pharmacodynamics of the drugs used to treat the disease.

Patients With Type 2 Diabetes: Anesthetic Management in the Ambulatory Setting. Part 1: Pathophysiology and Associated Disease States.

The increasing prevalence of diabetes mellitus in the general population has many implications for the ambulatory anesthesia provider. Complications, particularly associated with poor glycemic control, can affect multiple organ systems and jeopardize the safety of any planned anesthetic. It is essential that anesthesiologists and sedation providers have in-depth knowledge of the pathophysiology of diabetes mellitus and the comorbid conditions that commonly accompany it.

Inadvertent Endobronchial Intubation in a Patient With a Short Neck Length.

Inadvertent placement of the endotracheal tube into the right bronchus during intubation for general anesthesia is a fairly common occurrence. Many precautions should be taken by the anesthesia provider in order to minimize the incidence of endobronchial intubation, including bilateral auscultation of the lungs, use of the 21/23 rule, and palpation of the inflated endotracheal cuff at the sternal notch. These provisions, however, are not foolproof; anesthesia providers should realize that endobronchial intubation may occur from time to time because of variations in patient anatomy, changes in patient positioning, and cephalad pressures exerted during surgery.
