A Simple Risk Adjustment for Hospital-Level Nulliparous, Term, Singleton, Vertex, Cesarean Delivery Rates and Its Implications for Public Reporting.

BACKGROUND: The Joint Commission uses nulliparous, term, singleton, vertex, cesarean delivery (NTSV-CD) rates to assess hospitals' perinatal care quality through the Cesarean Birth measurement (PC-02). However, these rates are not risk-adjusted for maternal health factors, putting this measure at odds with the risk adjustment paradigm of most publicly reported hospital quality measures. Here, the authors tested whether risk adjustment for readily documented maternal risk factors affected hospital-level NTSV-CD rates in a large health system. METHODS: Included were all consecutive NTSV pregnancies from January 2019 to April 2023 across 10 hospitals in one health system. Logistic regression, adjusting for age, obesity, diabetes, and hypertensive disorders. was used to calculate hospital-level risk-adjusted NTSV-CD rates by multiplying observed vs. expected ratios for each hospital by the systemwide unadjusted NTSV-CD rate. The authors calculated intrahospital risk differences between unadjusted and risk-adjusted rates and calculated the percentage of hospitals qualifying for different reporting status after risk adjustment using the 30% Joint Commission reporting threshold rate. RESULTS: Of 23,866 pregnancies, 6,550 (27.4%) had cesarean deliveries. Across 10 hospitals, the number of deliveries ranged from 393 to 7,671, with unadjusted NTSV-CD rates ranging from 21.0% to 30.5%. Risk-adjusted NTSV-CD rates ranged from 21.5% to 30.4%, with absolute intrahospital differences in risk-adjusted vs. unadjusted rates ranging from -1.33% (indicating lower rate after risk adjustment) to 3.37% (indicating higher rate after risk adjustment). Three of 10 (30.0%) hospitals qualified for different reporting statuses after risk adjustment. CONCLUSION: Risk adjustment for age, obesity, diabetes, and hypertensive disorders is feasible and resulted in meaningful changes in hospital-level NTSV-CD rates with potentially impactful consequences for hospitals near The Joint Commission reporting threshold.

Transfusion targets and adverse events in pediatric perioperative acute Anemia.

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.

Simulation Training Effects on Resident-Perceived Readiness for Obstetric Anesthesia Rotation.

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.

Spinal anesthesia in infants undergoing urologic surgery duration greater than 60 minutes.

INTRODUCTION: Spinal anesthesia (SA) has been safely utilized in infants. There are limited data regarding the safety and efficacy of SA in pediatric urologic surgery lasting ≥60 min. We outlined the perioperative course for infants undergoing single-injection 0.5% plain bupivacaine SA-only for urologic procedures lasting ≥60 min. OBJECTIVE: To characterize the safety and efficacy of SA for urologic surgery in infants lasting ≥60 min. METHODS: We reviewed our prospectively maintained database of infants undergoing SA for urologic procedures lasting ≥60 min from May 2018 to March 2021. Patients received preoperative intranasal dexmedetomidine, some received intranasal fentanyl, and all patients received lidocaine cream applied preoperatively over the lumbar spine. Oral sucrose on a pacifier was provided as needed, and the patient's arms were swaddled for the procedure. Success was defined as no conversion to general anesthesia. Time points for start/end of spinal injection, procedure duration, wheels in/out of operating room (OR), and discharge were collected. RESULTS: Of 245 cases conducted with SA during the study period, 76 (31%) infants underwent surgery lasting ≥60 min. Of these, 73 (96%) were successfully completed with SA alone. In the 3 cases converted to general anesthesia, 2 (67%) required mask anesthesia after 96 and 169 min (for the last <10 min of surgery), and one was converted to intubation before start of surgery. Median patient age was 6 (IQR 5-7) months, and median procedure length was 95 (IQR 75-120) minutes. Following initial preoperative intranasal dexmedetomidine ± fentanyl, at least one additional dose of IV sedative was given in 27 (36%) cases at a median time of 90 (IQR 60-120) minutes into surgery. Following closure, patients exited the OR after a median 10 (IQR 8-12) minutes and subsequently discharged after spending a median of 73 (IQR 61-96) minutes in recovery. DISCUSSION: We describe pediatric urologic surgical cases lasting ≥60 min that employed single-injection intrathecal bupivacaine alone without adjunct intrathecal agents. In this report, SA was safely utilized in infants undergoing urologic procedures lasting at least 60 min, with about 40% of patients receiving additional IV dexmedetomidine and fentanyl. Non-medication measures (swaddling, oral sucrose) were important for maximizing patient comfort. Communication between surgeon and anesthesia as cases progress is key to maintaining adequate anesthesia. CONCLUSION: A single-injection bupivacaine-only spinal anesthesia approach for urologic surgery lasting over an hour and up to 3 h is safe and effective in infants. Selecting appropriate candidates for SA should be a joint decision between the surgeon and the anesthesiologist.

Impact of Mentorship, by Gender, on Career Trajectory in an Academic Anesthesiology Department: A Survey Study.

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.

A call for innovation in fetal monitoring during fetal surgery.

PURPOSE: A growing number of fetal procedures are performed at specialized fetal care centers for congenital problems that classically would have poor outcomes despite advanced postnatal management. Consistent fetal monitoring is integral to the safety of these challenging and innovative surgeries. However, standardization of fetal monitoring during various forms of fetal surgery has yet to be established. MATERIALS AND METHODS: We searched all articles on literature platforms until August 2019 using the terms "fetal surgery," "fetal monitoring," and "fetal interventions." Titles and abstracts were screened by our coauthors to determine the type of fetal monitoring used in these cases. RESULTS: The search identified 1,625 citations, of which the 50 citations considered most pertinent were included in this review. CONCLUSIONS: Fetal monitoring during in utero fetal surgeries continues to be challenging because of limited physical fetal access and technological aspects. Innovations in fetal cardiac monitoring during fetal surgeries have the potential for continuous and high-fidelity hemodynamic and physiologic monitoring, with the goal of early detection and treatment of fetal compromise.

Analgesic considerations for induction of labor.

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.

Postoperative Critical Events Associated With Obstructive Sleep Apnea: Results From the Society of Anesthesia and Sleep Medicine Obstructive Sleep Apnea Registry.

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.

Fetal Surgery in the Era of SARS-CoV-2 Pandemic: A Single-Institution Review.

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.

Antinausea Protocol Reduces Hospital Length of Stay for Laparoscopic Nissen Fundoplication.

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.

Attitudes of Hospice Providers Regarding Intrathecal Targeted Drug Delivery for Patients With Cancer.

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.

It is Electric! Electroconvulsive Therapy for Refractory Central Pain and Comorbid Psychiatric Disease.

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.

Accidental Ketamine Overdose on Induction of General Anesthesia.

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.

Hemorrhagic Shock After Epicardial Pacing Wire Removal: A Case Report.

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.

Clinical implications of de Barsy syndrome.

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.

The Extraordinary Case of the Hungry Woman: Large Foreign Body Ingestion With Respiratory Arrest.

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.

Timing of postoperative respiratory emergencies: when do they really occur?

PURPOSE OF REVIEW: Opioid-induced postoperative respiratory depression has garnered attention and calls for vigilance. However, a higher level of monitoring equates to increased use of hospital resources and is impractical to apply for all postoperative patients. Understanding the temporal pattern of postoperative respiratory emergency occurrences would allow for improved triage of monitoring resources for high-risk patients. Our objective is to describe the temporal pattern of risk of postoperative opioid-induced respiratory failure. RECENT FINDINGS: The literature suggests that postoperative opioid-induced respiratory depression is more frequent and severe than previously believed. In response, national patient advocacy groups have proposed improved postoperative monitoring of high-risk patients, especially those with sleep-disordered breathing. Published series of patients who have had adverse respiratory events suggest that the first 24 postsurgical hours comprise the period of highest risk, with most events occurring within the first 12 h. Further, study findings have suggested that adverse respiratory events often occur shortly after administration of opioid analgesics. SUMMARY: Emerging evidence indicates that the first postsurgical day carries the highest risk of adverse respiratory events, and this risk is often associated with opioid administration. Resources for increased monitoring should be directed to these high-risk times.

The impact of perioperative packed red blood cell transfusion on survival in epithelial ovarian cancer.

OBJECTIVE: Perioperative packed red blood cell transfusion (PRBCT) has been implicated as a negative prognostic marker in surgical oncology. There is a paucity of evidence on the impact of PRBCT on outcomes in epithelial ovarian cancer (EOC). We assessed whether PRBCT is an independent risk factor of recurrence and death from EOC. METHODS: Perioperative patient characteristics and process-of-care variables (defined by the National Surgical Quality Improvement Program) were retrospectively abstracted from 587 women who underwent primary EOC staging between January 2, 2003, and December 29, 2008. Associations with receipt of PRBCT were evaluated using univariate logistic regression models. The associations between receipt of PRBCT and disease-free survival and overall survival were evaluated using multivariable Cox proportional hazards models and using propensity score matching and stratification, respectively. RESULTS: The rate of PRBCT was 77.0%. The mean ± SD units transfused was 4.1 ± 3.1 U. In the univariate analysis, receipt of PRBCT was significantly associated with older age, advanced stage (≥ IIIA), undergoing splenectomy, higher surgical complexity, serous histologic diagnosis, greater estimated blood loss, longer operating time, the presence of residual disease, and lower preoperative albumin and hemoglobin. Perioperative packed red blood cell transfusion was not associated with an increased risk for recurrence or death, in an analysis adjusting for other risk factors in a multivariable model or in an analysis using propensity score matching or stratification to control for differences between the patients with and without PRBCT. CONCLUSIONS: Perioperative packed red blood cell transfusion does not seem to be directly associated with recurrence and death in EOC. However, lower preoperative hemoglobin was associated with a higher risk for recurrence. The need for PRBCT seems to be a stronger prognostic indicator than the receipt of PRBCT.
