Abstract
STUDY OBJECTIVE To evaluate the association between pretransfusion and posttransfusion hemoglobin concentrations and the outcomes of children undergoing noncardiac surgery. DESIGN Retrospective review of patient records. We focused on initial postoperative hemoglobin concentrations, which may provide a more useful representation of transfusion adequacy than pretransfusion hemoglobin triggers (the latter often cannot be obtained during acute surgical hemorrhage). SETTING Single-center, observational cohort study. PATIENTS We evaluated all pediatric patients undergoing noncardiac surgery who received intraoperative red blood cell transfusions from January 1, 2008, through December 31, 2018. INTERVENTIONS None. MEASUREMENTS Associations between pre- and posttransfusion hemoglobin concentrations (g/dL), hospital-free days, intensive care unit admission, postoperative mechanical ventilation, and infectious complications were evaluated with multivariable regression modeling. MAIN RESULTS In total, 113,713 unique noncardiac surgical procedures in pediatric patients were evaluated, and 741 procedures met inclusion criteria (median [range] age, 7 [1-14] years). Four hundred ninety-eight patients (68%) with a known preoperative hemoglobin level had anemia; of these, 14% had a preexisting diagnosis of anemia in their health record. Median (IQR) pretransfusion hemoglobin concentration was 8.1 (7.4-9.2) g/dL and median (IQR) initial postoperative hemoglobin concentration was 10.4 (9.3-11.6) g/dL. Each decrease of 1 g/dL in the initial postoperative hemoglobin concentration was associated with increased odds of transfusion within the first 24 postoperative hours (odds ratio [95% CI], 1.62 [1.37-1.93]; P < .001). No significant relationships were observed between postoperative hemoglobin concentrations and hospital-free days (P = .56), intensive care unit admission (P = .71), postoperative mechanical ventilation (P = .63), or infectious complications (P = .74). CONCLUSIONS In transfused patients, there was no association between postoperative hemoglobin values and clinical outcomes, except the need for subsequent transfusion. Most transfused patients presented to the operating room with anemia, which suggests a potential opportunity for perioperative optimization of health before surgery.

Abstract
Background Beginning an unfamiliar rotation can be challenging as residents must expand their knowledge and skills to meet new clinical expectations, work with a new team of providers, and sometimes care for a new patient demographic. This may detract from learning, resident well-being, and patient care. Methods We implemented an obstetric anesthesia simulation session for anesthesiology residents prior to their first obstetric anesthesia rotation and measured the effect on residents' self-perceived preparedness. Results The simulation session increased residents' feelings of preparedness for the rotation and increased residents' confidence in specific obstetric anesthesia skills. Conclusions Importantly, this study shows the potential for the use of a prerotation, rotation-specific simulation session to better prepare learners for rotations.

Abstract
INTRODUCTION Mentorship has been identified as a key component of success in business and in academic medicine. METHODS After institutional review board approval of the study, an email survey was sent to anesthesiologists in one anesthesiology department to assess mentorship status. A survey link was sent to nonrespondents at 2 weeks and 4 weeks. All participants were deidentified. The identification of a mentor was compared by gender, academic rank, and years of practice. RESULTS Among 233 anesthesiologists, 103 (44.2%) responded to the survey. More than 90% of survey respondents agreed or strongly agreed that having a mentor is important to career success. Of the 103 respondents, 31 (30%) indicated they had a mentor. Overall, 84% of the identified mentors were men; however, this percentage differed significantly between men and women respondents (95% versus 60%; P = .03). Characteristics associated with having a mentor included younger age (P = .007), fewer years since finishing training (P = .004), and working full time (P = .02). For respondent age and years since finishing training, there was some evidence that the association was dependent on the gender of the respondent (age-by-gender interaction, P = .08; experience-by-gender interaction, P = .08). DISCUSSION Anesthesiologists in this department believed that mentorship led to more academic success. Few women mentors were reported, and women were unlikely to identify a mentor once advanced past an assistant professor rank. Most respondents believed that mentorship was important for overall career success, but only approximately one-third identified a mentor at the time of the survey.

Abstract
Induction of labor may be indicated to minimize maternal and fetal risks. The rate of induction is likely to increase as recent evidence supports elective induction at 39 weeks gestation. We review methods of induction and then analgesic options as they relate to indications and methods to induce labor. We specifically focus on parturients at high risk for anesthetic complications including those requiring anticoagulation, and those with cardiac disease, obesity, chorioamnionitis, prior spinal instrumentation, elevated intracranial pressure, known or anticipated difficult airway, thrombocytopenia, and preeclampsia. Guidelines regarding timing of anticoagulation dosing with neuraxial anesthetic techniques have been defined through consensus statements. Early epidural placement may be beneficial in patients with cardiac disease, obesity, anticipated difficult airway, and HELLP syndrome. Questions remain regarding how early is too early for epidural placement, what options are safest for patients with bacteremia, and what pain relief should be offered to those unable to tolerate cervical exams in early labor.

Abstract
BACKGROUND Induction of labor continues to become more common. We analyzed induction of labor and timing of obstetric and anesthesia work to create a model to predict the induction-anesthesia interval and the induction-delivery interval in order to co-ordinate workload to occur when staff are most available. METHODS Patients who underwent induction of labor at a single medical center were identified and multivariable linear regression was used to model anesthesia and delivery times. Data were collected on date of birth, race/ethnicity, body mass index, gestational age, gravidity, parity, indication for labor induction, number of prior deliveries, time of induction, induction agent, cervical dilation, effacement, and fetal station on admission, date and time of anesthesia administration, date and time of delivery, and delivery type. RESULTS A total of 1746 women met inclusion criteria. Associations which significantly influenced time from induction of labor to anesthesia and delivery included maternal age (anesthesia P <0.001, delivery P =0.002), body mass index (both P <0.001), prior vaginal delivery (both P <0.001), gestational age (anesthesia P <0.001, delivery P <0.018), simplified Bishop score (both P <0.001), and first induction agent (both P <0.001). Induction of labor of nulliparous women at 02:00 h and parous women at 04:00 or 05:00 h had the highest estimated probability of the mother having her first anesthesia encounter and delivering during optimally staffed hours when our institution's specialty personnel are most available. CONCLUSIONS Time to obstetric and anesthesia tasks can be estimated to optimize induction of labor start times, and shift anesthesia and delivery workload to hours when staff are most available.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) patients are at increased risk for pulmonary and cardiovascular complications; perioperative mortality risk is unclear. This report analyzes cases submitted to the OSA Death and Near Miss Registry, focusing on factors associated with poor outcomes after an OSA-related event. We hypothesized that more severe outcomes would be associated with OSA severity, less intense monitoring, and higher cumulative opioid doses. METHODS Inclusion criteria were age ≥18 years, OSA diagnosed or suspected, event related to OSA, and event occurrence 1992 or later and <30 days postoperatively. Factors associated with death or brain damage versus other critical events were analyzed by tests of association and odds ratios (OR; 95% confidence intervals [CIs]). RESULTS Sixty-six cases met inclusion criteria with known OSA diagnosed in 55 (83%). Patients were middle aged (mean = 53, standard deviation [SD] = 15 years), American Society of Anesthesiologists (ASA) III (59%, n = 38), and obese (mean body mass index [BMI] = 38, SD = 9 kg/m); most had inpatient (80%, n = 51) and elective (90%, n = 56) procedures with general anesthesia (88%, n = 58). Most events occurred on the ward (56%, n = 37), and 14 (21%) occurred at home. Most events (76%, n = 50) occurred within 24 hours of anesthesia end. Ninety-seven percent (n = 64) received opioids within the 24 hours before the event, and two-thirds (41 of 62) also received sedatives. Positive airway pressure devices and/or supplemental oxygen were in use at the time of critical events in 7.5% and 52% of cases, respectively. Sixty-five percent (n = 43) of patients died or had brain damage; 35% (n = 23) experienced other critical events. Continuous central respiratory monitoring was in use for 3 of 43 (7%) of cases where death or brain damage resulted. Death or brain damage was (1) less common when the event was witnessed than unwitnessed (OR = 0.036; 95% CI, 0.007-0.181; P < .001); (2) less common with supplemental oxygen in place (OR = 0.227; 95% CI, 0.070-0.740; P = .011); (3) less common with respiratory monitoring versus no monitoring (OR = 0.109; 95% CI, 0.031-0.384; P < .001); and (4) more common in patients who received both opioids and sedatives than opioids alone (OR = 4.133; 95% CI, 1.348-12.672; P = .011). No evidence for an association was observed between outcomes and OSA severity or cumulative opioid dose. CONCLUSIONS Death and brain damage were more likely to occur with unwitnessed events, no supplemental oxygen, lack of respiratory monitoring, and coadministration of opioids and sedatives. It is important that efforts be directed at providing more effective monitoring for OSA patients following surgery, and clinicians consider the potentially dangerous effects of opioids and sedatives-especially when combined-when managing OSA patients postoperatively.

Abstract
Objective To cope with the changing health care services in the era of SARS-CoV-2 pandemic. We share the institutional framework for the management of anomalous fetuses requiring fetal intervention at Mayo Clinic, Rochester, Minnesota. To assess the success of our program during this time, we compare intraoperative outcomes of fetal interventions performed during the pandemic with the previous year. Patients We implemented our testing protocol on patients undergoing fetal intervention at our institution between March 1, and May 15, 2020, and we compared it with same period a year before. A total of 17 pregnant patients with anomalous fetuses who met criteria for fetal intervention were included: 8 from 2019 and 9 from 2020. Methods Our testing protocol was designed based on our institutional perinatal guidelines, surgical requirements from the infection prevention and control (IPAC) committee, and input from our fetal surgery team, with focus on urgency of procedure and maternal SARS-CoV-2 screening status. We compared the indications, types of procedures, maternal age, gestational age at procedure, type of anesthesia used, and duration of procedure for cases performed at our institution between March 1, 2020, and May 15, 2020, and for the same period in 2019. Results There were no statistically significant differences among the number of cases, indications, types of procedures, maternal age, gestational age, types of anesthesia, and duration of procedures (P values were all >.05) between the pre–SARS-CoV-2 pandemic in 2019 and the SARS-CoV-2 pandemic in 2020. Conclusions Adoption of new institutional protocols during SARS-CoV-2 pandemic, with appropriate screening and case selection, allows provision of necessary fetal intervention with maximal benefit to mother, fetus, and health care provider.

Abstract
OBJECTIVE The perioperative course of patients undergoing laparoscopic Nissen fundoplication (LNF) was reviewed to determine whether the use of a new treatment protocol consisting of total intravenous anesthesia (TIVA) plus triple antiemetic therapy was associated with shorter hospital length of stay (HLOS). DESIGN Retrospective cohort. SETTING Single academic center. PARTICIPANTS The study comprised 448 patients. Fifty-four patients undergoing LNF who received TIVA were compared with 394 who received standard inhalational anesthesia (non-TIVA) between January 2010 and June 2017. INTERVENTIONS Patients who received TIVA were compared with those who received non-TIVA. MEASUREMENTS AND MAIN RESULTS In multivariate analysis, TIVA was significantly associated with reduced HLOS (odds ratio 2.91, 95% confidence interval 1.47-5.78) and a 7.8% reduction in cost of care (p < 0.01). Female sex, length of surgery, and older age all were negatively associated with length of stay. The association between the use of TIVA and reduced HLOS and institutional cost was compared using univariate and multivariate analyses. CONCLUSIONS The use of TIVA in patients undergoing uncomplicated LNF shortens HLOS and is associated with reduced cost of care. This study illustrates that communication among surgeons and anesthesiologists results in improved patient care.

Abstract
Pain is one of the most commonly experienced and feared symptoms faced by patients with a serious illness. For these patients, intrathecal drug delivery systems (IDDSs) provide greater potency and/or few systemic side effects. However, despite these benefits, the integration and management of IDDS for patients receiving hospice care has not been previous studied. An electronic, 18-question survey was sent to 200 hospice practitioners (physicians, nurse practitioners and nurses) in the state of Minnesota to explore their experience, confidence, and the perceived barriers to caring for patients with IDDS while being cared for on hospice. Providers were identified though mailing lists from the Minnesota Network of Hospice and Palliative Care organization. The survey was administered by the Mayo Clinic Survey Research Center with institutional review board approval. Slightly more than 50% of respondents have ever cared for a patient with an intrathecal pump. If a patient had a pump in place, only 28% of providers expressed confidence in managing their pain. Additionally, only 3 of 10 respondents felt that adjusting an intrathecal pump should be the first option when a patient with an IDDS in place had increased pain. Indeed, the vast majority (over 80%) of respondents preferred the use of systemic therapies for primary pain management. Access to IDDS vendors for changes/refills in the home is identified as another barrier with over 50% of respondents either unaware of an available vendor or reporting no vendor available. There are numerous self-reported barriers to ongoing use of IDDS with patients receiving hospice care.

Abstract
Epicardial pacing wires are routinely used to avoid hemodynamic instability due to perioperative arrhythmias after cardiac surgery. In rare cases, pacing wires themselves can be associated with potentially life-threatening complications. Herein, we present a novel case of hemorrhagic shock and hemoperitoneum after temporary epicardial pacing wire removal.

Abstract
Central pain syndromes are a complex, diverse group of clinical conditions that are poorly understood. We present a patient with progressive, debilitating central pain and co-existing mood disorders that was refractory to multimodal pharmacologic and nonpharmacologic therapies, but that ultimately responded to electroconvulsive therapy (ECT). The patient described it at various times as her skin being "lit on fire," "stabbed," "squeezed like a boa constrictor," or itching unbearably. She underwent a course of three sequential ECT treatments during her hospitalization and it dramatically decreased her pain. She began maintenance ECT, and a rate of roughly one treatment a month provided persistent pain suppression. Despite this lack of evidence, ECT has a favorable safety profile and can be considered in the therapeutic armamentarium for patients who have exhausted standard treatment regimens who continue to have suffering in the setting of central pain syndromes and coexisting mood disorders.

Abstract
BACKGROUND Ketamine is used as an induction and sedation agent in emergency departments and operating rooms throughout the country. Despite its widespread clinical use, there are few cases of significant morbidity and mortality attributed to ketamine overdose in the clinical setting. CASE REPORT The anesthesia provider in the room was an oral maxillofacial surgeon who inadvertently took out a more highly concentrated bottle of ketamine that is typically used for pediatric patients. The patient received 950 mg (100 mg/ml concentration) of intravenous ketamine instead of the intended 95 mg (10 mg/ml concentration). After the ketamine was given, there were no signs to any involved provider that a mistake had occurred until the wake-up appeared to be unusually prolonged. CONCLUSIONS Despite this, the patient did not demonstrate any systemic effects such as hemodynamic or CNS perturbations other than prolonged awakening. This case highlights one (drug overdose) of many causes of delayed emergence from anesthesia and reminds the provider caring for the patient to be mindful of drug concentrations used when preparing to sedate a patient, as relying on effects of the parent drug is not always adequate.

Abstract
BACKGROUND De Barsy syndrome is a rare, autosomal recessive syndrome characterized by cutis laxa, progeroid appearance, ophthalmic opacification, skeletal malformations, growth delays, and intellectual disability. AIMS The aim of this case series is to identify the anesthetic considerations in the clinical management of patients with de Barsy syndrome. METHODS A retrospective case review from 1968 to 2016 was performed at a single tertiary medical center to identify patients with de Barsy syndrome who underwent anesthesia for diagnostic and surgical procedures. We collected and analyzed the perioperative records and following data: age, sex, American Society of Anesthesiologists physical status, relevant comorbidities, surgical procedures, anesthesia management, and observed complications. RESULTS Three patients underwent 64 unique anesthetics for a diverse collection of diagnostic and surgical procedures. An array of anesthetics and techniques were successfully used. Observations of the perioperative period found 7 episodes of intraoperative hyperthermia (>38.3°), a single difficult airway requiring fiberoptic bronchoscopic-guided intubation, and repeatedly difficult intravenous access. CONCLUSION This expanded case series suggests that providers caring for patients with de Barsy syndrome should be aware of potential challenges with airway management, vascular access, and temperature monitoring.

Abstract
Repeated ingestion of small objects has been previously reported in the psychiatric literature. We recently had a patient with repeated intentional foreign body ingestion syndrome who developed complete airway obstruction and cardiac arrest after ingesting a computer mouse tracking ball. We use our case to suggest a pathway that can be used for similar emergent airway problems.

Abstract
We reviewed 94 cases of prehospital ventricular fibrillation (VF) to determine aspects of field response that predicted outcome. Only one of 37 patients (3 percent) failing to achieve rhythms other than VF or asystole after the first two defibrillations survived to hospital discharge compared to nine of 57 (16 percent) achieving organized rhythms by this point (p less than 0.05). None of 56 patients failing to achieve pulses prior to transport survived to hospital discharge compared to ten of 38 achieving field pulses (p less than 0.01). However, survival to discharge was not significantly different between patients who developed pulses immediately with their rhythms (5 of 17, 29 percent) and those who were defibrillated into pulseless rhythms but later developed pulses in the field (five of 21, 24 percent). Thus, for prehospital VF, the best field response identifies potential survivors prior to hospital arrival. In addition, the frequent occurrence and potentially favorable outcome of an initially pulseless rhythm necessitates reevaluation of current therapy.
