Influence of Social Media on Applicant Perceptions of Anesthesiology Residency Programs During the COVID-19 Pandemic: Quantitative Survey.

BACKGROUND: Social media may be an effective tool in residency recruitment, given its ability to engage a broad audience; however, there are limited data regarding the influence of social media on applicants' evaluation of anesthesiology residency programs. OBJECTIVE: This study evaluates the influence of social media on applicants' perceptions of anesthesiology residency programs during the COVID-19 pandemic to allow programs to evaluate the importance of a social media presence for residency recruitment. The study also sought to understand if there were differences in the use of social media by applicant demographic characteristics (eg, race, ethnicity, gender, and age). We hypothesized that given the COVID-19 pandemic restrictions on visiting rotations and the interview process, the social media presence of anesthesiology residency programs would have a positive impact on the recruitment process and be an effective form of communication about program characteristics. METHODS: All anesthesiology residency applicants who applied to Mayo Clinic Arizona were emailed a survey in October 2020 along with statements regarding the anonymity and optional nature of the survey. The 20-item Qualtrics survey included questions regarding subinternship rotation completion, social media resource use and impact (eg, "residency-based social media accounts positively impacted my opinion of the program"), and applicant demographic characteristics. Descriptive statistics were examined, and perceptions of social media were stratified by gender, race, and ethnicity; a factor analysis was performed, and the resulting scale was regressed on race, ethnicity, age, and gender. RESULTS: The survey was emailed to 1091 individuals who applied to the Mayo Clinic Arizona anesthesiology residency program; there were 640 unique responses recorded (response rate=58.6%). Nearly 65% of applicants reported an inability to complete 2 or more planned subinternships due to COVID-19 restrictions (n=361, 55.9%), with 25% of applicants reporting inability to do any visiting student rotations (n=167). Official program websites (91.5%), Doximity (47.6%), Instagram (38.5%), and Twitter (19.4%) were reported as the most used resources by applicants. The majority of applicants (n=385, 67.3%) agreed that social media was an effective means to inform applicants, and 57.5% (n=328) of them indicated that social media positively impacted their perception of the program. An 8-item scale with good reliability was created, representing the importance of social media (Cronbach α=.838). There was a positive and statistically significant relationship such that male applicants (standardized ß=.151; P=.002) and older applicants (ß=.159; P<.001) had less trust and reliance in social media for information regarding anesthesiology residency programs. The applicants' race and ethnicity were not associated with the social media scale (ß=-.089; P=.08). CONCLUSIONS: Social media was an effective means to inform applicants, and generally positively impacted applicants' perception of programs. Thus, residency programs should consider investing time and resources toward building a social media presence to improve resident recruitment.

Low-Dose Ketamine Infusion for Perioperative Pain Management in Patients Undergoing Laparoscopic Gastric Bypass: A Prospective Randomized Controlled Trial.

INTRODUCTION: Obesity is a common comorbidity seen in the perioperative setting and is associated with many diseases including cardiovascular disease and obstructive sleep apnea. Laparoscopic Roux-en-Y gastric bypass is the gold standard surgical treatment for patients whose weight is refractory to diet and exercise. Caring for these patients perioperatively presents unique challenges to anesthesiologists and is associated with an increased risk of adverse respiratory events. In our study, we hypothesize that a low-dose perioperative ketamine infusion will reduce opioid consumption and improve analgesia when compared to standard therapy. METHODS: This is a single-center, prospective randomized controlled study enrolling 35 patients in total. Patients were randomized equally into the ketamine and control group. Preop, intraop, and postop management regimens were standardized. The ketamine group received a 0.3 mg/kg ideal body weight ketamine bolus after induction followed by a 0.2 mg/kg/hr ketamine infusion continued into the postop setting for up to 24 hours. Data collected included total perioperative opioids used converted to oral morphine equivalents (ME), pain scores, side effects, hospital length of stay, and patient satisfaction captured via postoperative questionnaires. RESULTS: The use of perioperative opioid consumption was significantly lower in the ketamine group when compared with the control group (179.9 ME versus 248.7 ME, P=0.03). There was no statistically significant difference in pain scores or hospital length of stay postoperatively between the two groups. There were also no reported adverse respiratory events, prolonged sedation, agitation, or other side effects reported in either group. The patient satisfaction questionnaires showed a significant difference with the ketamine group reporting lower maximum pain scores, a decrease in how pain limited activities of daily living once discharged, and increased hospital pain management satisfaction scores. CONCLUSIONS: Perioperative low-dose ketamine infusions significantly reduced opioid consumption in morbidly obese patients undergoing laparoscopic gastric bypass surgery.

Nontraditional Transesophageal Echocardiographic Views to Evaluate Hepatic Vasculature in Orthotopic Liver Transplantation and Liver Resection Surgery.

BACKGROUND: Utilization of intraoperative transesophageal echocardiography (TEE) during orthotopic liver transplantation (OLT) is expanding annually in high-volume transplant centers. During OLT intraoperative TEE is used to gather real-time information on cardiovascular function and intravascular volume status. Although standardized TEE views exist, there are nontraditional views described in the literature which have the potential to diagnose evolving pathology and define normal variants of hepatic vasculature. METHODS: A literature review was completed utilizing the PubMed database for English-only, peer-reviewed publications discussing nontraditional use of intraoperative TEE during OLT and hepatic vascular-related surgeries from 2009 to 2019. Both case reports and review articles were considered. RESULTS: The PubMed literature search offered 8 publications for analysis, including 7 case reports and 1 article review, revealing several nontraditional TEE views not included in a comprehensive transesophageal echocardiographic examination. These nontraditional views were generally obtained using modifications to the transgastric and bicaval views to visualize liver vasculature. We present the various techniques for obtaining these views from the 8 articles identified. CONCLUSIONS: At high-volume transplant centers, TEE use during OLT is increasing. Intraoperative TEE is a valuable tool to assess hepatic vascular structures critical to allograft/organ function without interruption of the surgical procedure. Nontraditional use of TEE to diagnose intraoperative noncardiac pathology in OLT appears underutilized and underreported. The modified hepatic and modified transgastric views we describe can be used to evaluate hepatic vasculature, influence surgical decision-making and ultimately improve patient care.

The Impact of Social Media on Anesthesia Resident Recruitment.

BACKGROUND: The role of the internet continues to expand, particularly in the realm of graduate medical education. Residency program directors commonly use websites to share information with applicants. As social media (SM) use grows, the role of residency-based SM accounts in recruiting prospective residents remains unclear. OBJECTIVE: We sought to delineate which SM platforms prospective anesthesia residents have accounts and which platforms they use to research anesthesia residency programs. METHODS: Following the results of the National Residency Match Program (NRMP) in March 2018, we anonymously surveyed anesthesiology resident candidates from all three Mayo Clinic residency sites and inquired about which SM platforms candidates maintain a profile, which they used to evaluate residencies, and to what degree the content influenced their decision. RESULTS: A total of 219 surveys were distributed that resulted in 89 responses (40.6%, 89/219). Most respondents have a Facebook account (94.4%, 84/89) while Doximity was the most commonly used SM platform to research programs (86.5%, 77/89). Most respondents (52.8%, 47/89) felt the presence of a residency-based SM account had an impact on their evaluation of prospective programs. Most respondents (50.5%, 45/89) used an internet search to research programs, while a large percentage (42.7%, 38/89) used a combination of internet search engines and SM platforms. CONCLUSIONS: While an internet search was the most commonly used technique to research programs, many applicants also used SM platforms. Doximity was the most commonly SM platform, however, more applicants have Facebook accounts, suggesting programs can use this platform to reach prospective applicants.

Evaluation of Clinical Factors Associated with Adverse Drug Events in Patients Receiving Sub-Anesthetic Ketamine Infusions.

INTRODUCTION: Sub-anesthetic ketamine is frequently used as an analgesic to reduce perioperative opioid consumption and has also been shown to have antidepressant effects. Side effects of ketamine include dizziness, diplopia, nystagmus, and psychomimetic effects. It is unclear what clinical factors may be associated with ketamine-related adverse drug events (ADEs). METHODS: We performed a retrospective review of 95 patients who received sub-anesthetic ketamine infusions at our institution. Data examined associations between ketamine-related ADEs and various clinical characteristics including chronic pain, depression, or psychiatric disorder, patient physical characteristics, chronic opioid use, perioperative opioid use, dose and duration of ketamine infusions, pain scores, and perioperative medications such as serotonergic agents, central nervous system (CNS) depressants, and analgesics. RESULTS: Overall incidence of ketamine-related ADEs was 29.5% and the incidence of psychomimetic effects was 14.8%. We observed that patients with a history of depression have a lower incidence of ketamine-related ADEs compared to patients without a history of depression (10.3% vs 37.3%; p value = 0.007). CONCLUSION: Patients with depression were found to have a statistically significant reduction in the incidence of ketamine-related ADEs. We found no statistically significant positive associations between ketamine-related ADEs and other clinical factors such as a history of chronic pain, psychiatric disease, patient physical characteristics, perioperative opioid use, dose of ketamine infusion, or co-administration of other CNS depressants.

Persistent hiccups following cervical epidural steroid injection with betamethasone.

Singultus (hiccups lasting longer than 48 hours) is a described complication following epidural steroid injections, sacroiliac joint injections, and facet joint injections. The underlying etiology is not completely understood, but it is a condition that can be distressing to patients. Our case presentation involves a 62-year-old male presenting for cervical epidural steroid injection. He subsequently developed persistent hiccups that resolved after medical therapy. When approaching these patients, it is critical to evaluate for potentially life-threatening etiologies before progressing down a treatment algorithm.

The effect of ampule size of fentanyl on perioperative intravenous opioid dosing.

BACKGROUND AND AIMS: There are limited data on the effect of ampule size on drug dosing. The objective of this study is to determine the effect of ampule size on perioperative opioid dosing and post-anesthesia care unit (PACU) outcomes. MATERIAL AND METHODS: This was a retrospective review of patients undergoing robotically assisted laparoscopic radical prostatectomy before and after a 5-ml fentanyl ampule was discontinued. The primary outcome was intraoperative opioid administration divided into fentanyl at induction of anesthesia, total fentanyl, and total opioid. Secondary outcomes observed in PACU included the opioid administered, visual analog scale (VAS) pain scores, postoperative nausea and vomiting, and length of stay in PACU. RESULTS: A total of 100 patients (50 PRE and 50 POST) were included. In the intraoperative opioid administration, mean (SD) of fentanyl at induction was 117.0 (49.3) in PRE group and 85.0 (35.4) µg in POST group (P < 0.01). The total fentanyl requirement was 247.0 (31.0) in PRE group and 158.5 (85.1) µg in POST group (P < 0.01). The total opioid in intravenous morphine equivalents (IVME) was 34.1 (5.8) in PRE group and 23.2 (6.8) mg in POST group (P < 0.01). Among the secondary outcomes, mean (SD) of IVME of opioid was 7.7 (8.2) in PRE group and 9.9 (8.1) mg in POST group (P = 0.18). The VAS pain score on arrival was 0.7 (1.4) in PRE group and 3.8 (3.3) in POST group (P < 0.01). The cumulative VAS pain score was 2.3 (2.0) in PRE group and 3.3 (2.2) in POST group (P < 0.01). The length of stay was significantly more in POST group, 193.8 (75.8) minutes, as compared with PRE group, 138.6 (61.0) minutes (P < 0.01). CONCLUSIONS: A change in the ampule size significantly affected intraoperative dosing, PACU pain scores, and PACU length of stay in patients undergoing robotically assisted laparoscopic radical prostatectomy under general anesthesia. This was explained by clinician's desire to conserve the drug and avoid the complex process of narcotic waste disposal.

Perioperative considerations for patients with sickle cell disease: a narrative review.

PURPOSE: Approximately 200,000 individuals worldwide are born annually with sickle cell disease (SCD). Regions with the highest rates of SCD include Africa, the Mediterranean, and Asia, where its prevalence is estimated to be 2-6% of the population. An estimated 70,000-100,000 people in the United States have SCD. Due to enhanced newborn screening, a better understanding of this disease, and more aggressive therapy, many sickle cell patients survive into their adult years and present more frequently for surgery. SOURCE: The authors identified relevant medical literature by searching PubMed, MEDLINE®, EMBASE™, Scopus™, Web of Science, and Google Scholar databases for English language publications appearing from 1972-September 2016. Case reports, abstracts, review articles, and original research articles were reviewed-with particular focus on the pathophysiology and medical management of SCD and any anesthesia-related issues. PRINCIPAL FINDINGS: Perioperative physicians should be familiar with the triggers of a sickle cell crisis and vaso-occlusive disease. Sickle cell disease affects various organ systems, including the central nervous, cardiovascular, pulmonary, genitourinary, and musculoskeletal systems. Preoperative assessment should focus on end-organ dysfunction. Controversy continues regarding if and when sickle cell patients should receive transfusions and which anesthetic technique (regional or general) confers any benefits. Timely, appropriate, and sufficient analgesia is critical, especially when patients experience a vaso-occlusive crisis, acute chest syndrome, or acute postoperative pain. CONCLUSION: Effective management of SCD patients in the perioperative setting requires familiarity with the epidemiology, pathophysiology, clinical manifestations, and treatment of SCD.

Insertion of intra-oral electrodes for cranial nerve monitoring using a Crowe-Davis retractor.

Acoustic neuroma resection is an example of a neurosurgical procedure where the brainstem and multiple cranial nerves are at risk for injury. Electrode placement for monitoring of the glossopharyngeal and hypoglossal nerves during acoustic neuroma resection can be challenging. The purpose of this report is to illustrate the use of a device for intra-oral electrode placement for intraoperative monitoring of the glossopharyngeal and hypoglossal nerves. A 60-year-old male presented for acoustic neuroma resection. Under general anesthesia, a Crowe-Davis retractor was used to open the mouth, providing access to the posterior pharynx. For glossopharyngeal monitoring, two bent subdermal needle electrodes were inserted just lateral to the uvula. Two additional electrodes were inserted on the lateral tongue to monitor the hypoglossal nerve. Cranial nerves monitoring was conducted utilizing both free running and triggered electromyography of the trigeminal and facial nerves in addition to the lower cranial nerves. The tumor was resected successfully. Monitoring of the cranial nerves (including the glossopharyngeal and hypoglossal nerves) revealed no concerning responses. The Crowe-Davis retractor and the technique described allowed insertion of electrodes for neural monitoring, contributing to neural preservation.

Survey of pain specialists regarding conversion of high-dose intravenous to neuraxial opioids.

The conversion of high-dose intravenous (IV) opioids to an equianalgesic epidural (EP) or intrathecal (IT) dose is a common clinical dilemma for which there is little evidence to guide practice. Expert opinion varies, though a 100 IV:10:EP:1 IT conversion ratio is commonly cited in the literature, especially for morphine. In this study, the authors surveyed 724 pain specialists to elucidate the ratios that respondents apply to convert high-dose IV morphine, hydromorphone, and fentanyl to both EP and IT routes. Eighty-three respondents completed the survey. Conversion ratios were calculated and entered into graphical scatter plots. The data suggest that there is wide variation in how pain specialists convert high-dose IV opioids to EP and IT routes. The 100 IV:10 EP:1 IT ratio was the most common answer of survey respondent, especially for morphine, though also for hydromorphone and fentanyl. Furthermore, more respondents applied a more aggressive conversion strategy for hydromorphone and fentanyl, likely reflecting less spinal selectivity of those opioids compared with morphine. The authors conclude that there is little consensus on this issue and suggest that in the absence of better data, a conservative approach to opioid conversion between IV and neuraxial routes is warranted.

Intravenous sub-anesthetic ketamine for perioperative analgesia.

Ketamine, an N-methyl-d-aspartate antagonist, blunts central pain sensitization at sub-anesthetic doses (0.3 mg/kg or less) and has been studied extensively as an adjunct for perioperative analgesia. At sub-anesthetic doses, ketamine has a minimal physiologic impact though it is associated with a low incidence of mild psychomimetic symptoms as well as nystagmus and double vision. Contraindications to its use do exist and due to ketamine's metabolism, caution should be exercised in patients with renal or hepatic dysfunction. Sub-anesthetic ketamine improves pain scores and reduces perioperative opioid consumption in a broad range of surgical procedures. In addition, there is evidence that ketamine may be useful in patients with opioid tolerance and for preventing chronic postsurgical pain.

Acute vertigo in an anesthesia provider during exposure to a 3T MRI scanner.

Vertigo induced by exposure to the magnetic field of a magnetic resonance imaging (MRI) scanner is a well-known phenomenon within the radiology community but is not widely appreciated by other clinical specialists. Here, we describe a case of an anesthetist experiencing acute vertigo while providing sedation to a patient undergoing a 3 Tesla MRI scan. After discussing previous reports, and the evidence surrounding MRI-induced vertigo, we review potential etiologies that include the effects of both static and time-varying magnetic fields on the vestibular apparatus. We conclude our review by discussing the occupational standards that exist for MRI exposure and methods to minimize the risks of MRI-induced vertigo for clinicians working in the MRI environment.

Painful Ejaculation with Cyclobenzaprine: A Case Report and Literature Review.

INTRODUCTION: Sexual dysfunction is a well-known side effect of antidepressants. Painful ejaculation is a rare side effect that has been reported with the use of some psychiatric drugs such as triclyclic antidepressants. Cyclobenzaprine is a muscle relaxant that is structurally similar to tricyclic antidepressants. It is the most commonly prescribed muscle relaxant in the United States and accounts for 18% of all prescriptions written for chronic back pain. METHODS: A 55-year-old man was referred to our pain medicine clinic for evaluation and treatment of pain with ejaculation. MAIN OUTCOME MEASURE: The main outcome measure was to review the current published literature and case reports on painful ejaculation from medication use, in particular tricyclic antidepressants. RESULTS: After discontinuation of cyclobenzaprine, our patient's sexual dysfunction resolved. This result was consistent with the literature reviewed on the topic. CONCLUSION: Painful ejaculation is likely an underreported side effect of tricyclic antidepressants and cyclobenzaprine use. Fortunately, these symptoms are reversible and discontinuation of these medications is typically an effective cure. K raus MB , W ie CS , G orlin AW , W isenbaugh ES , and R osenfeld DM .

Attributes associated with patient perceived outcome in an academic chronic pain clinic.

OBJECTIVES: Patient satisfaction is tied to outcome, but there is scant literature on the relationship of patient perceived outcome and attributes of the pain clinic visit, including the patient interaction with the pain management specialist. The primary purpose of this study is to identify attributes of the patient-provider interaction most strongly associated with patient perceived outcome of their clinic visit. The secondary aim is to correlate patient perceived outcome with patient self-rated overall health. METHODS: A patient satisfaction survey conducted via phone approximately 3 weeks after the patient's pain clinic visit. RESULTS: The response rate was 60.2%; 987 patient surveys collected between 2006 and 2010 were used in the analysis. Four factors were significantly associated with the outcome: (1) Explanations by the physician of the patient's condition and treatment, (2) clear instructions regarding post-appointment activities, (3) knowing the patient as a person, and (4) the patient's self-rated health. In terms of the secondary objective, those who answered very good/excellent regarding their self-rated health had an 87% increased odds of better (very good/excellent) outcome of their pain clinic visit (or 1.87 times the odds of better outcome) compared with those who answered poor/fair/good. CONCLUSIONS: Our results suggest that pain physicians may positively impact patient perceived outcomes of clinic visits by explaining the patient's condition and treatment, providing instructions, and taking the time to understand the patient and their values.

Clinical implications of the transversus abdominis plane block in adults.

The transversus abdominis plane (TAP) block is a relatively new regional anesthesia technique that provides analgesia to the parietal peritoneum as well as the skin and muscles of the anterior abdominal wall. It has a high margin of safety and is technically simple to perform, especially under ultrasound guidance. A growing body of evidence supports the use of TAP blocks for a variety of abdominal procedures, yet, widespread adoption of this therapeutic adjunct has been slow. In part, this may be related to the limited sources for anesthesiologists to develop an appreciation for its sound anatomical basis and the versatility of its clinical application. As such, we provide a brief historical perspective on the TAP block, describe relevant anatomy, review current techniques, discuss pharmacologic considerations, and summarize the existing literature regarding its clinical utility with an emphasis on recently published studies that have not been included in other systematic reviews or meta-analyses.
