Identification, Characterization, and Ranking of Candidate Metrics for Selection to Anesthesiology Residency: An Iterative Survey of Program Directors.

Background: The primary aim of this study was to identify and stratify candidate metrics used by anesthesiology residency program directors (PDs) to develop their residency rank lists through the National Resident Matching Program. Methods: Sixteen PDs comprised the participants, selected for diversity in geography and program size. We used a 3-round iterative survey to identify and stratify candidate metrics. In the first round, participants listed metrics they planned to use to evaluate candidates. In the second round, metrics from the first round were ranked by importance, and criteria were solicited to define an exceptional, strong, average, marginal, and uncompetitive candidate for each metric. In the third round, aggregated results were presented and participants refined their rankings. Results: Of the 16 PDs selected, 15 participated in the first and second survey rounds, and 10 in the third. Eighteen candidate metrics were indicated by 8 or more PDs for residency selection. All 10 PDs from the final round identified passing Step 1 of the United States Medical Licensing Exam (USMLE) and the absence of "red flags" like a failed rotation as key selection metrics, both averaging an importance score of 4.9 out of 5. Other metrics identified by all PDs included clerkship evaluation comments, USMLE Step 2 scores, class rank, letters of recommendation, personal statement, and program and geographical signals. Conclusions: The study reveals key metrics anesthesiology residency PDs use for candidate ranking, which may offer candidates insights into their competitiveness for anesthesiology residency.

Preoperative preparation and premedication of bariatric surgical patient.

The prevalence of obesity has tripled worldwide over the past four decades. The United States has the highest rates of obesity, with 88% of the population being overweight and 36% obese. The UK has the sixth highest prevalence of obesity. The problem of obesity is not isolated to the developed world and has increasingly become an issue in the developing world as well. Obesity carries an increased risk of many serious diseases and health conditions, including type 2 diabetes, heart disease, stroke, sleep apnea, and certain cancers. Our ability to take care of this population safely throughout the perioperative period begins with a thorough and in-depth preoperative assessment and meticulous preparation. The preoperative assessment begins with being able to identify patients who suffer from obesity by using diagnostic criteria and, furthermore, being able to identify patients whose obesity is causing pathologic and physiologic changes. A detailed and thorough anesthesia assessment should be performed, and the anesthesia plan individualized and tailored to the specific patient's risk factors and comorbidities. The important components of the preoperative anesthesia assessment and patient preparation in the patient suffering from obesity include history and physical examination, airway assessment, medical comorbidities evaluation, functional status determination, risk assessment, preoperative testing, current weight loss medication, and review of any prior weight loss surgeries and their implications on the upcoming anesthetic. The preoperative evaluation of this population should occur with sufficient time before the planned operation to allow for modifications of the preoperative management without needing to delay surgery as the perioperative management of patients suffering from obesity presents significant practical and organizational challenges.

Hyperoxia After Return of Spontaneous Circulation in Cardiac Arrest Patients.

Current guidelines emphasize the use of 100% oxygen during cardiopulmonary resuscitation after cardiac arrest. When patients are ventilated for variable periods after return of spontaneous circulation (ROSC), hyperoxia causes increased morbidity and mortality by overproduction of reactive oxygen species. Various patient, volunteer, and animal studies have shown the harmful effects of hyperoxia. This mini-review article aims to expand the potential clinical spectrum of hyperoxia on individual organ systems leading to organ dysfunction. A framework to achieve and maintain normoxia after ROSC is proposed. Despite the harmful considerations of hyperoxia in critically ill patients, additional safety studies including dose-effect, level and onset of the reactive oxygen species effect, and safe hyperoxia applicability period after ROSC, need to be performed in various animal and human models to further elucidate the role of oxygen therapy after cardiac arrest.

Artificial Intelligence in Echocardiography for Anesthesiologists.

Echocardiography is a unique diagnostic tool for intraoperative monitoring and assessment of patients with cardiovascular diseases. However, there are high levels of interoperator variations in echocardiography interpretations that could lead to inaccurate diagnosis and incorrect treatment. Furthermore, anesthesiologists are faced with the additional challenge to interpret echocardiography and make decisions in a limited timeframe from these complex data. The need for an automated, less operator-dependent process that enhances speed and accuracy of echocardiography analysis is crucial for anesthesiologists. Artificial intelligence is playing an increasingly important role in the medical field and could help anesthesiologists analyze complex echocardiographic data while adding increased accuracy and consistency to interpretation. This review aims to summarize practical use of artificial intelligence in echocardiography and discusses potential limitations and challenges in the future for anesthesiologists.

Prolonged continuous infraclavicular brachial plexus perineural infusion following replantation of a mid-humeral amputation.

Replantation of a traumatic upper extremity amputation is a complex process accompanied by prolonged hospitalization, extended rehabilitation, and potential for graft failure secondary to poor perfusion to the distal extremity. The patient is faced with repeat visits to the operating room in addition to severe acute and chronic pain issues. We present the case of an 18-year-old male treated with prolonged continuous peripheral nerve blockade following traumatic left mid-humeral amputation and subsequent replantation. The patient maintained infraclavicular brachial plexus catheterization until hospital discharge, a course spanning 33 days and six follow-up surgical procedures. The patient was pain free and had been weaned off all opioids at a 4-week outpatient surgical debridement. Prolonged continuous infraclavicular brachial plexus blockade following replantation surgery has numerous potential benefits including augmentation of perfusion to the injured extremity, management of severe acute post-traumatic pain, and prevention of the chronic pain associated with transected nerves.
