Carotid approach to anterior circulation thromboembolectomy in an adult with failing fontan physiology: a case report.

BACKGROUND: Anesthetic management of an adult with failing Fontan physiology is complicated given inherent anatomical and physiological alterations. Neurosurgical interventions including thromboembolectomy may be particularly challenging given importance of blood pressure control and cerebral perfusion. CASE PRESENTATION: We describe a 29 year old patient born with double outlet right ventricle (DORV) with mitral valve atresia who after multi-staged surgeries earlier in life, presented with failing Fontan physiology. She was admitted to the hospital almost 29 years after her initial surgeries to undergo workup for a dual heart and liver transplant in the context of a failing Fontan with elevated end diastolic pressures, NYHA III heart failure symptoms, and liver cirrhosis from congestive hepatopathy. During the workup in the context of holding anticoagulation for invasive procedures, she developed a middle cerebral artery (MCA) stroke requiring a thromboembolectomy via left carotid artery approach. DISCUSSION AND CONCLUSIONS: This case posed many challenges to the anesthesiologist including airway control, hemodynamic and cardiopulmonary monitoring, evaluation of perfusion, vascular access, and management of anticoagulation in an adult patient in heart and liver failure with Fontan physiology undergoing thromboembolectomy for MCA embolic stroke.

Introduction of an Analgesia Prescription Guideline Can Reduce Unused Opioids After Cardiac Surgery: A Before and After Cohort Study.

OBJECTIVE(S): The authors aimed to assess whether the introduction of a tailored Analgesia Prescription Guideline would decrease the amount of unused opioid following discharge from cardiac surgery. DESIGN: Prospective, observational, before and after study. SETTING: Quaternary care university hospital. PARTICIPANTS: A total of 191 participants who underwent cardiac surgery requiring midline sternotomy and cardiopulmonary bypass. There were 99 participants in the before cohort (prior to introduction of the Analgesia Prescription Guideline), and 92 participants in the after cohort (after introduction of the Analgesia Prescription Guideline). INTERVENTIONS: Using prospectively collected observational data on participant opioid consumption in the before cohort, a tailored Analgesia Prescription Guideline was developed. This guideline then was introduced to all opioid-prescribing providers in the cardiothoracic surgery department. Prospective data then were collected in the after cohort of participants. Opioid prescription practices and opioid consumption between the two groups then were compared. MEASUREMENTS AND MAIN RESULTS: Opioid prescriptions were given to 62/99 participants (63%) in the before cohort, and 48/92 (52%) in the after cohort (rate difference 0.1, CI 95% -0.26, 0.046). In the before cohort, the mean (± standard deviation) number of opioid tablets prescribed, used, and leftover was 26 (±10), 11 (±10), and 15 (±12), respectively. In the after cohort, the mean number of opioid tablets prescribed, used, and leftover was 18 (mean difference -8, CI 95% -12, -5), 10 (mean difference -1, CI 95% -5, 3), and 8 (mean difference -7, CI 95% -11, -3), respectively. There were 110/191 (58%) participants using no opioids following discharge, and 10/191 (5%) still using opioids two weeks after discharge. There were no differences between groups with regard to demographics, opioid-related side effects, pain scores, satisfaction, opioid storage. and disposal practices. CONCLUSIONS: The development and implementation of a tailored Analgesia Prescription Guideline decreased the amount of opioids prescribed after cardiac surgery and resulted in lower numbers of unused leftover opioid tablets in the community. Patient comfort and satisfaction scores remained high.

Primer of COVID-19 Vaccines for the Perioperative Physician.

Dr. Emanuel Papper, the founding chairman of the Department of Anesthesiology at Columbia University, was passionate about research, training, and innovation. At an event held in his honor on March 20, 2021, experts came together to discuss the coronavirus disease 2019 (COVID-19) pandemic and its myriad challenges. Dr. Wellington Sun, MD, of Vaxcellerant LLC, an expert in infectious disease and vaccine research and development, presented a "Primer of COVID-19 vaccines for the perioperative physician." Operation Warp Speed was successful in producing multiple efficacious and safe vaccines for use in the United States and around the globe. Their development and authorization for emergency use occurred in an unprecedented timespan of <1 year. Technology such as V-SAFE has helped to accrue extensive postdevelopment safety data that will be utilized for licensure of these vaccines. The COVID-19 vaccine success is tempered by the knowledge that severe acute respiratory syndrome coronavirus 2 continues its natural selection of variants that threaten the efficacy of vaccines. Important questions remain regarding the future of the COVID-19 pandemic, severe acute respiratory syndrome coronavirus 2 variants, successful vaccination strategies, and preparedness for future pandemics.

Anesthetic Management and Considerations for Electrophysiology Procedures.

The number of electrophysiology (EP) procedures being performed has dramatically increased in recent years. This escalation necessitates a full understanding by the general anesthesiologist as to the risks, specific considerations, and comorbidities that accompany these now common procedures. Procedures reviewed in this article include atrial fibrillation and flutter ablation, supraventricular tachycardia ablation, ventricular tachycardia ablation, electrical cardioversion, pacemaker insertion, implantable cardioverter-defibrillator (ICD) insertion, and ICD lead extraction. General anesthetic considerations as well as procedure-specific concerns are discussed. Knowledge of these procedures will add to the anesthesiologist's armamentarium in safely caring for patients in the EP laboratory.

Fever of unknown origin: a retrospective review of pediatric patients from an urban, tertiary care center in Washington, DC.

BACKGROUND: Fever of unknown origin (FUO) continues to challenge clinicians to determine an etiology and the need for treatment. This study explored the most common etiologies, characteristics, and average cost of hospitalization for FUO in a pediatric population at an urban, tertiary care hospital in Washington, DC. METHODS: Records from patients admitted to Children's National Health System between September 2008 and April 2014 with an admission ICD-9 code for fever (780.6) were reviewed. The charts of patients 2-18 years of age with no underlying diagnosis and a temperature greater than 38.3 ºC for 7 days or more at time of hospitalization were included. Final diagnoses, features of admission, and total hospital charges were abstracted. RESULTS: 110 patients qualified for this study. The majority of patients (n = 42, 38.2%) were discharged without a diagnosis. This was followed closely by infection, accounting for 37.2% (n = 41) of patients. Rheumatologic disease was next (n = 16, 14.5%), followed by miscellaneous (n = 6, 5.4%) and oncologic diagnoses (n = 5, 4.5%). The average cost of hospitalization was 40,295 US dollars. CONCLUSIONS: This study aligns with some of the most recent publications which report undiagnosed cases as the most common outcome in patients hospitalized with FUO. Understanding that, often no diagnosis is found may reassure patients, families, and clinicians. The cost associated with hospitalization for FUO may cause clinicians to reconsider inpatient admission for diagnostic work-up of fever, particularly given the evidence demonstrating that many patients are discharged without a diagnosis.
