Anesthesia in remote locations

BACKGROUND: To perform step-by-step analysis of the different factors (material, anesthesia technique, human, and location) that led to major pneumothorax during an infrequent pediatric cardiac MRI and to prevent its occurrence in the future. Anesthesia equipment used in a remote location is often different than those in operating rooms. For magnetic resonance imaging (MRI), ventilation devices and monitors must be compatible with the magnetic fields. During cardiac MRI numerous apneas are required and, visual contact with the patient is limited for clinical evaluation...

The objective of this study was to evaluate and compare 2 different xylazine:ketamine combination anesthetic protocols in free-ranging beavers (Castor canadensis) . Twenty-two beavers (weighing 2.5 to 18.5 kg) were equally assigned to one of the following protocols: 1:10 xylazine:ketamine ratio and 3:10 xylazine:ketamine ratio. Using standard metabolic scaling, the following ranges of dosages were calculated and used: for the 1:10 xylazine:ketamine group 1.08 to 2.25 mg/kg (median = 1.2 mg/kg) of xylazine + 10...

BACKGROUND: Risk-appropriate care improves outcomes by ensuring birthing people and infants receive care at a facility prepared to meet their needs. Perinatal regionalization has particular importance in rural areas where pregnant people might not live in a community with a birthing facility or specialty care. Limited research focuses on operationalizing risk-appropriate care in rural and remote settings. Through the implementation of the Centers for Disease Control and Prevention (CDC) Levels of Care Assessment Tool (LOCATe), this study assessed the system of risk-appropriate perinatal care in Montana...

Myasthenic crisis (MC) is a rare and life-threatening manifestation of myasthenia gravis (MG) and is characterized by rapidly progressing weakness of respiratory and bulbar muscles leading to immobility, severe dyspnea, respiratory insufficiency, and possible aspiration. Early recognition and prompt treatment may prevent the development of further complications and the need for intubation, invasive mechanical ventilation, and ICU admission. Its diagnosis requires a high degree of clinical suspicion, and anesthesiologists, despite being prepared to deal with and provide anesthesia care to patients with MG, may not be immediately aware of the correct diagnosis and treatment of this medical emergency, and of the red flags that should prompt more invasive measures...

INTRODUCTION: The rate of general anesthesia (GA) use for pediatric dental treatment in Saskatchewan is among the highest in Canada. Although the prevalence of and risk factors for early childhood caries (ECC) has been reviewed nationally, few studies have focused on Saskatchewan. The objective of this study was to determine the prevalence of and predictive factors for dental treatment under GA in Saskatchewan. METHODS: This retrospective review focused on pediatric patients who required dental treatment under GA in Saskatchewan between 2015 and 2018...

Adverse respiratory events in the out-of-operation theatre premises can be challenging to anesthesiologists. Manual jaw thrust application by anesthesiologists can be a temporary solution during an adverse airway event in remote locations. This report highlights the utility of a novel collar in alleviating upper airway obstruction in a patient in the MRI suite under IV sedation. The Lubo collar provides an automated jaw thrust and can also be applied electively for patients undergoing MRI under sedation and who are at risk of upper airway obstruction...

Peroral endoscopic myotomy (POEM) is a promising natural orifice transluminal endoscopic procedure for the treatment of esophageal motility disorders, with similar effectiveness as of Heller myotomy. It is performed under general anesthesia in endoscopy suite. Creation of submucosal tunnel in the esophageal wall is a key component. The continuous insufflation of CO2 inadvertently tracks into surrounding tissues and leads to capno mediastinum, capno thorax, capno peritoneum, and subcutaneous emphysema. Thus, the challenges, for an anesthesiologist are not only providing remote location anesthesia, increased risk of aspiration during induction, but also early detection of these complications and specific emergency management...

INTRODUCTION: The COVID-19 pandemic has had a significant impact on the care of patients with urolithiasis. Recommendations and prioritization of endourologic surgical procedures vary among regions and a comprehensive overall international directive is needed. We used the Delphi method to obtain international consensus on managing urolithiasis patients during the pandemic. METHODS: A three-round Delphi process was used to elicit expert consensus (53 global key opinion leaders within the Endourological Society from 36 countries) on an extensive survey on management of endourologic patients in a pandemic...

Background: The Objective Structured Clinical Examination (OSCE) is part of the American Board of Anesthesiology (ABA) certification process. A simulated OSCE can aid examination preparation, but the COVID-19 pandemic prevented in-person simulation training. Therefore, we adapted our in-person simulated OSCE (SOSCE) as a Zoom-based telesimulation OSCE (ZOSCE), permitting examinees to participate remotely. Comparing this process with historical in-person SOSCE cohorts, we hypothesized that this telesimulation-based format would still be well received by the trainees as a substitute when it was not possible to provide in-person practice and formative assessment...

PURPOSE OF REVIEW: Patients presenting for non-operating room procedures are often 'too sick' for surgery and require specific anesthesia care in remote areas with logistical and scheduling challenges. RECENT FINDINGS: Increased complexity and scope of minimally invasive procedures have expanded this practice. In addition, the concept of therapeutic options other than conventional surgery is gaining traction. SUMMARY: Our review of recent literature confirms the complexity and supports the safety of providing care in non-operating room anesthesia locations...

PURPOSE OF REVIEW: To review advancements in care for pediatric patients in nonoperating room settings. RECENT FINDINGS: Advances in patient monitoring technology, utilization of Child Life specialists, and alternative staffing models are helping anesthesia providers meet the rising demand for coverage of pediatric nonoperating room anesthesia (NORA) cases. The Wake Up Safe and Pediatric Sedation Research Consortium registries are exploring outcome measures regarding the safety of pediatric anesthesia in off-site locations and have reported an increased risk for severe respiratory and cardiac adverse events when compared to OR anesthesia sites...

BACKGROUND: Sterilization clinics often occur in remote places where anesthesia machines and compressed oxygen are unavailable. This study describes the use of total injectable anesthesia in dogs and cats presented for sterilization in a remote location. RESULTS: A total of 100 animals were sterilized; 26 female cats (CF), 22 male cats (CM), 28 female dogs (DF), and 24 male dogs (DM). CF were anesthetized with dexmedetomidine (20 mcg/kg), ketamine (8 mg/kg) and hydromorphone (0...

Anesthesiology teams care for children in diverse locations, including diagnostic and interventional radiology, gastroenterology and pulmonary endoscopy suites, radiation oncology units, and cardiac catheterization laboratories. To provide safe, high-quality care, anesthesiologists working in these environments must understand the unique environmental and perioperative considerations and risks involved with each remote location and patient population. Once these variables are addressed, anesthesia and procedural teams can coordinate to ensure that patients and families receive the same high-quality care that they have come to expect in the operating room...

Anesthesia care performed outside the operating room is a growing area of pediatric anesthesia practice. The anesthesiology team expects to care for children in diverse locations, which include diagnostic and interventional radiology, gastroenterology and pulmonary endoscopy suites, radiation oncology sites, and the cardiac catheterization laboratory. To provide safe, high-quality care the anesthesiologist working in these environments must understand the unique environmental, logistical, and perioperative considerations and risks involved with each remote location...

Myocardial infarction (MI) remains the main contributor to morbidity and mortality worldwide. Therefore, research on this topic is mandatory. An easily and highly reproducible MI induction procedure is required to obtain further insight and better understanding of the underlying pathological changes. This procedure can also be used to evaluate the effects or potency of new and promising treatments (as drugs or interventions) in acute MI, subsequent remodeling and heart failure (HF). After intubation and pre-operative preparation of the animal, an anesthetic protocol with isoflurane was performed, and the surgical procedure was conducted quickly...

PURPOSE OF REVIEW: The prevalence of procedures performed outside of the operating room is steadily growing around the world, especially in the United States. This review aims to discuss the risks and safety of anesthesia performed in remote locations based on an up-to-date literature review, with a focus on the results from closed claims and other database analyses. RECENT FINDINGS: The published literature in the last decade shows that there is an increase in nonoperating room anesthesia cases and that the highest number of these cases are in gastroenterology endoscopy suites...

Using long-term, remote recordings of heart rate (fH ) on fully recovered, undisturbed lizards, we identified several components of heart rate variability (HRV) associated with respiratory sinus arrhythmia (RSA): 1.) A peak in the spectral representation of HRV at the frequency range of ventilation. 2.) These cardiorespiratory interactions were shown to be dependent on the parasympathetic arm of the autonomic nervous system. 3.) Vagal preganglionic neurons are located in discrete groups located in the dorsal motor nucleus of the vagus and also, in a ventro-lateral group, homologous to the nucleus ambiguus of mammals...

Objective The purpose of this study is to report our experience in using image-guided percutaneous radiofrequency ablation (RFA) for the treatment of osteoid osteoma (OO) and the subsequent duration of pain relief over a period of about six years (May 2013-March 2019; 70 months) at a tertiary-care hospital in a developing nation. Methods A retrospective study was performed at the radiology department of Aga Khan University, Karachi, Pakistan. All patients who had undergone image-guided percutaneous RFA for OO between May 2013-March 2019 were included...

PURPOSE: Magnetoencephalography (MEG) is a noninvasive tool used clinically for presurgical evaluation of patients with medically intractable epilepsy. These recordings require patients to lie still for prolonged periods of time in a magnetically shielded room. Children or uncooperative adults with epilepsy may require sedation to reduce movement artefact and obtain high-quality recordings. Potential challenges related to the use of total intravenous anesthesia in the MEG environment include limited access to the patient's airway, remote location, suppression of cortical activity, and increased patient care expenses...

BACKGROUND: Radiation therapy in pediatric patients often requires anesthesia and poses environmental challenges. Monitoring must be done remotely to limit radiation exposure to the provider. Airway access can be limited by masks or frames. Care is often delivered in relatively inaccessible locations in the hospital. While individual institutions have reported their outcomes, this case series aims to review a multicenter registry of significant adverse events and make recommendations for improved care...
