Success and Challenge When Returning to Clinical Practice: A Case Series in Anesthesiologist Re-Entry.

INTRODUCTION: Anesthesiologists returning to clinical practice pose unique challenges for licensing and credentialing boards. Few institutions provide re-education. We describe the physician refresher/re-entry program at our College of Medicine. METHODS: We launched the physician re-entry program in 2006. This individualized program re-educates physicians who left clinical practice for any reason and are seeking to return. We report results achieved for 12 anesthesiologists who successfully completed the course between August 2012 and February 2018. RESULTS: Seven men and five women left their practices for various reasons, which included relocation, family or medical reasons, substance use, and burnout. None left practice for medical negligence. Range away from clinical activity was 0-10 years. Five had active licenses. Seven were US graduates and five were international. Nine of 12 achieved their goals. Of the 3 others, 1 did not pursue her goal, another did not obtain a residency, and the other just finished the program. Seven out of 9 (78%) achieved their goal within 1 year of course completion. DISCUSSION: Despite our small sample size, our experience to successfully return inactive physicians to the workforce adds to the scant literature and experience in refreshing inactive physicians. Our trainees return to practice serving communities across the country and are now a pivotal part of the anesthesiology workforce. Thus, this program not only services individual physicians, but the whole community affected by their absence.

Utilization of Smartphone Applications by Anesthesia Providers.

Health care-related apps provide valuable facts and have added a new dimension to knowledge sharing. The purpose of this study is to understand the pattern of utilization of mobile apps specifically created for anesthesia providers. Smartphone app stores were searched, and a survey was sent to 416 anesthesia providers at 136 anesthesiology residency programs querying specific facets of application use. Among respondents, 11.4% never used, 12.4% used less than once per month, 6.0% used once per month, 12.1% used 2-3 times per month, 13.6% used once per week, 21% used 2-3 times per week, and 23.5% used daily. Dosage/pharmaceutical apps were rated the highest as most useful. 24.6% of the participants would pay less than $2.00, 25.1% would pay $5.00, 30.3% would pay $5-$10.00, 9.6% would pay $10-$25.00, 5.1% would pay $25-$50.00, and 5.1% would pay more than $50.00 if an app saves 5-10 minutes per day or 30 minutes/week. The use of mobile phone apps is not limited to reiterating information from textbooks but provides opportunities to further the ever-changing field of anesthesiology. Our survey illustrates the convenience of apps for health care professionals. Providers must exercise caution when selecting apps to ensure best evidence-based medicine.

Using Bronchoscopy to Detect Acquired Tracheoesophageal Fistula in Mechanically Ventilated Patients.

INTRODUCTION: An acquired Tracheoesophageal fistula (TEF) is commonly caused by a malignancy or trauma, with pulmonary infection or aspiration being the presenting symptom. However, in the critical care setting the presentation can be subtle and may present with difficult ventilation. High endotracheal tube cuff pressures can lead to tracheal erosions and thus increasing the chances for developing a TEF. Prolonged intubation in the presence of other risk factors like poor general state of health, episodic hypotension, nasogastric tubes, and repeated intubations can increase the likelihood of developing an acquired TEF. Angioedema of the airway is a rare but potentially devastating complication of angiotensin converting enzyme inhibitors (ACE-I) that could further add insult to the tracheal mucosa, predisposing to an acquired TEF. CASE PRESENTATION: An elderly woman with multiple comorbidities and requiring mechanical ventilation, developed angioedema following intake of ACE inhibitor for hypertension. The ensuing airway edema made weaning off mechanical ventilation difficult. After repeated attempts at extubation, tracheostomy was performed. With the loss of airway after tracheostomy, the possibility of TEF was considered given her multiple risk factors and intra-operative findings of the tracheal mucosa. CONCLUSIONS: While it may be difficult to predict who will actually develop a TEF, it is prudent to identify those at risk and take precautionary measures to prevent one. Emphasis should be placed on daily endotracheal cuff manometric pressure check to prevent ischemic changes of the tracheal mucosa resulting from high cuff pressures. Also, bronchoscopy could be used after extubating susceptible patients to detect an acquired TEF.

Improving Patient Safety through Simulation Training in Anesthesiology: Where Are We?

There have been colossal technological advances in the use of simulation in anesthesiology in the past 2 decades. Over the years, the use of simulation has gone from low fidelity to high fidelity models that mimic human responses in a startlingly realistic manner, extremely life-like mannequin that breathes, generates E.K.G, and has pulses, heart sounds, and an airway that can be programmed for different degrees of obstruction. Simulation in anesthesiology is no longer a research fascination but an integral part of resident education and one of ACGME requirements for resident graduation. Simulation training has been objectively shown to increase the skill-set of anesthesiologists. Anesthesiology is leading the movement in patient safety. It is rational to assume a relationship between simulation training and patient safety. Nevertheless there has not been a demonstrable improvement in patient outcomes with simulation training. Larger prospective studies that evaluate the improvement in patient outcomes are needed to justify the integration of simulation training in resident education but ample number of studies in the past 5 years do show a definite benefit of using simulation in anesthesiology training. This paper gives a brief overview of the history and evolution of use of simulation in anesthesiology and highlights some of the more recent studies that have advanced simulation-based training.

Recovery following desflurane versus sevoflurane anesthesia for outpatient urologic surgery in elderly females.

BACKGROUND: An unresolved question is the time required for the ability to return to complex tasks following anesthesia. OBJECTIVES: This study aims to characterize the severity and duration of cognitive impairment following sevoflurane or desfluane anesthesia after brief surgery using tests of cognitive ability to objectively testing performance. PATIENTS AND METHODS: This study is a double blinded randomized controlled trial. Patients were randomized to receive either a desflurane or sevoflurane-based anesthetic. On the morning of the surgery the subjects performed baseline cognitive task tests (Mini Mental Status exam, Trail Making Test Part A and B, Digit Symbol Coding, Hopkins Verbal Learning Test, Stroop Color and Word Test to determine baseline cognitive function. Cognitive testing was repeated 30 minutes and 1 hour after surgery whereas Modified Telephone Interview for Cognitive Status (TICS-M) and Memory Aging Telephone Screen (MATS) was used on the following day of surgery. RESULTS: Trail Making Test Part B cognitive test showed statistically significant in comparison for pre and post exposure of anesthetics. This difference was seen in the desflurane group. Other cognitive tests did not show differences on exposure to the anesthetic gases. CONCLUSIONS: This study questioned the difference between volatile anesthetic agent's effects on patients completing a battery of neurocognitive tests attempting to answer if one agent has a more profound effect. Our study shows no statistically significant cognitive decline except for those in the Trail Making Part B in the Desflurane group. This conclusion is limited by the inherent limitations of the study, but does reinforce that the systemic inflammatory response from the surgery contributes cognitive impairment.

Atraumatic intubation: experience using a 5.0 endotracheal tube without a stylet for laryngeal surgery.

OBJECTIVES/HYPOTHESIS: Vocal fold injury is a well-know complication of intubation, with rates reported as high as 69%. Laryngology textbooks recommend the use of a small endotracheal tube (ETT) to help avoid these complications and optimize visualization. Case reports have suggested that the rigid stylet can lead to laryngeal injury. Given the additional risks, intubation without the stylet is our preferred practice. There is limited documentation in the literature regarding this viewpoint. Our study investigated the feasibility of and potential barriers to intubation using 5.0 ETT without a stylet. STUDY DESIGN: Prospective study. METHODS: Consecutive adult patients undergoing laryngeal surgery were recruited for intubation with a 5.0 ETT without a stylet. Demographic data, specialty and training level of the intubator, and factors that would predict a difficult intubation were recorded. Descriptive statistical analysis was performed. RESULTS: Findings of the participants (n = 67) included average American Society of Anesthesiologists (ASA) physical status classification (2.2), average Mallampati score (1.7), average Cormack-Lehane grade (1.5), and average body mass index (28.0). Five patients (7.4%) required intubation using a stylet, and one of these five participants was intubated initially with a stylet. Of these five participants, 80% required use of a GlideScope (P < .001), and they had significantly higher ASA classification (P = .047) and number of intubation attempts (P = .042). One patient sustained an oropharyngeal injury during intubation with a stylet. No participants had laryngeal injury. CONCLUSIONS: Most patients can be intubated successfully using a 5.0 ETT without a stylet. There were no cases of laryngeal trauma with this technique. LEVEL OF EVIDENCE: 2b.

Carbon monoxide-releasing molecule-2 enhances coagulation and diminishes fibrinolytic vulnerability in diluted plasma in vitro.

BACKGROUND: A carbon monoxide-releasing molecule (tricarbonyldichlororuthenium (II) dimer; CORM-2) enhances coagulation and attenuates vulnerability to fibrinolysis in normal and hemophiliac human plasma. We tested the hypothesis that plasma diluted with resuscitative fluids would demonstrate improved coagulation and decreased fibrinolytic vulnerability after exposure to CORM-2. METHODS: Normal, platelet-poor plasma was diluted 0%, 20%, 30%, 40%, or 50% with 0.9% NaCl (NS) or low-molecular-weight hydroxyethyl starch (VOL) and, subsequently, exposed to 0 µmol/L or 100 µmol/L CORM-2 before activation with tissue factor (n = 4 per condition). Additional plasma samples diluted with NS or VOL (0% or 30%) were exposed to 0 µmol/L or 100 µmol/L CORM-2 and 0 U/mL or 100 U/mL tissue-type plasminogen activator to assess fibrinolytic vulnerability (n = 8 per condition). Thrombelastographic data were collected until either clot strength stabilized or clot lysis occurred, as appropriate. RESULTS: CORM-2 exposure maintained normal to supranormal velocity of clot formation and strength in plasma diluted up to 40% with NS. In contrast, although CORM-2 exposure improved coagulation kinetics, dilution with VOL markedly degraded thrombus formation kinetics. Similarly, fibrinolytic vulnerability to tissue-type plasminogen activator was markedly improved by CORM-2 exposure in samples diluted with NS, whereas VOL-diluted thrombi were still abnormally weak and easily lysed compared with undiluted samples despite CORM-2 exposure. CONCLUSIONS: CORM-2 exposure attenuated the decrease in coagulation kinetics and enhancement of fibrinolytic vulnerability associated with hemodilution. Extensive preclinical investigation remains to be performed to determine the route of administration, safety, and efficacy of CORM-2 and other CORMs to treat trauma-associated bleeding.
