Evaluating the Women's Empowerment and Leadership Initiative: Supporting mentorship, career satisfaction, and well-being among pediatric anesthesiologists.

The Society for Pediatric Anesthesia launched the Women's Empowerment and Leadership Initiative (WELI) in 2018 to empower highly productive women pediatric anesthesiologists to achieve equity, promotion, and leadership. WELI is focused on six career development domains: promotion and leadership, networking, conceptualization and completion of projects, mentoring, career satisfaction, and sense of well-being. We sought feedback about whether WELI supported members' career development by surveys emailed in November 2020 (baseline), May 2021 (6 months), and January 2022 (14 months). Program feedback was quantitatively evaluated by the Likert scale questions and qualitatively evaluated by extracting themes from free-text question responses. The response rates were 60.5% (92 of 152) for the baseline, 51% (82 of 161) for the 6-month, and 52% (96 of 185) for the 14-month surveys. Five main themes were identified from the free-text responses in the 6- and 14-month surveys. Members reported that WELI helped them create meaningful connections through networking, obtain new career opportunities, find tools and projects that supported their career advancement and promotion, build the confidence to try new things beyond their comfort zone, and achieve better work-life integration. Frustration with the inability to connect in-person during the coronavirus-19 pandemic was highlighted. Advisors further stated that WELI helped them improve their mentorship skills and gave them insight into early career faculty issues. Relative to the baseline survey, protégés reported greater contributions from WELI at 6 months in helping them clarify their priorities, increase their sense of achievement, and get promoted. These benefits persisted through 14 months. Advisors reported a steady increase in forming new meaningful relationships and finding new collaborators through WELI over time. All the members reported that their self-rated mentoring abilities improved at 6 months with sustained improvement at 14 months. Thus, programs such as WELI can assist women anesthesiologists and foster gender equity in career development, promotion, and leadership.

Achieving Greater Health Equity: An Opportunity for Anesthesiology.

Anesthesiology and anesthesiologists have a tremendous opportunity and responsibility to eliminate health disparities and to achieve health equity. We thus examine health disparity and health equity through the lens of anesthesiology and the perspective of anesthesiologists. In this paper, we define health disparity and health care disparities and provide tangible, representative examples of the latter in the practice of anesthesiology. We define health equity, primarily as the desired antithesis of health disparity. Finally, we propose a framework for anesthesiologists, working toward mitigating health disparity and health care disparities, advancing health equity, and documenting improvements in health care access and health outcomes. This multilevel and interdependent framework includes the perspectives of the patient, clinician, group or department, health care system, and professional societies, including medical journals. We specifically focus on the interrelated roles of social identity and social determinants of health in health outcomes. We explore the foundational role that clinical informatics and valid data collection on race and ethnicity have in achieving health equity. Our ability to ensure patient safety by considering these additional patient-specific factors that affect clinical outcomes throughout the perioperative period could substantially reduce health disparities. Finally, we explore the role of medical journals and their editorial boards in ameliorating health disparities and advancing health equity.

Empowering Women as Leaders in Pediatric Anesthesiology: Methodology, Lessons, and Early Outcomes of a National Initiative.

Research has shown that women have leadership ability equal to or better than that of their male counterparts, yet proportionally fewer women than men achieve leadership positions and promotion in medicine. The Women's Empowerment and Leadership Initiative (WELI) was founded within the Society for Pediatric Anesthesia (SPA) in 2018 as a multidimensional program to help address the significant career development, leadership, and promotion gender gap between men and women in anesthesiology. Herein, we describe WELI's development and implementation with an early assessment of effectiveness at 2 years. Members received an anonymous, voluntary survey by e-mail to assess whether they believed WELI was beneficial in several broad domains: career development, networking, project implementation and completion, goal setting, mentorship, well-being, and promotion and leadership. The response rate was 60.5% (92 of 152). The majority ranked several aspects of WELI to be very or extremely valuable, including the protégé-advisor dyads, workshops, nomination to join WELI, and virtual facilitated networking. For most members, WELI helped to improve optimism about their professional future. Most also reported that WELI somewhat or absolutely contributed to project improvement or completion, finding new collaborators, and obtaining invitations to be visiting speakers. Among those who applied for promotion or leadership positions, 51% found WELI to be somewhat or absolutely valuable to their application process, and 42% found the same in applying for leadership positions. Qualitative analysis of free-text survey responses identified 5 main themes: (1) feelings of empowerment and confidence, (2) acquisition of new skills in mentoring, coaching, career development, and project implementation, (3) clarification and focus on goal setting, (4) creating meaningful connections through networking, and (5) challenges from coronavirus disease 2019 (COVID-19) and the inability to sustain the advisor-protégé connection. We conclude that after 2 years, the WELI program has successfully supported career development for the majority of protégés and advisors. Continued assessment of whether WELI can meaningfully contribute to attainment of promotion and leadership positions will require study across a longer period. WELI could serve as a programmatic example to support women's career development in other subspecialties.

Self-reported awareness during general anesthesia in pediatric patients: A study from Wake Up Safe.

BACKGROUND: Awareness under general anesthesia occurs rarely, but can result in emotional trauma. Although well-studied in adults, there is a paucity of data on unintentional awareness in children. AIMS: This case series examines instances of self-reported awareness registered with Wake Up Safe, a patient safety organization that maintains a database of adverse events in pediatric anesthesia. METHODS: Cases of self-reported intraoperative awareness submitted to Wake Up Safe from January 1, 2010 to May 31, 2020 were reviewed for circumstances, causative factors, and level of harm. RESULTS: Fourteen cases of self-reported intraoperative awareness out of 555 360 cases in patients aged 5-20 years were noted during the study period. Overall incidence of awareness was 2.52 (95% CI: 1.38-4.23) cases per 100 000 patients, or approximately 1:40 000. Self-reported intraoperative awareness was more frequently associated with cardiac and gastrointestinal endoscopic procedures. Incidence for cardiac procedures was 20.34 (95% CI: 8.18-41.90) cases per 100 000 patients. Incidence for gastrointestinal endoscopic procedures was 7.74 (95% CI: 1.60-22.62) cases per 100 000 patients. Most patients were assessed to have suffered harm. CONCLUSIONS: Self-reported intraoperative awareness is a rare complication in pediatric patients that has implications for harm. Compared to awareness cases elicited by a questionnaire method, cases of self-reported awareness during general anesthesia may represent those that have a greater impact. A preoperative discussion of intraoperative awareness should be considered for procedures that carry a higher likelihood of awareness in order to mitigate harm.

East/West Visiting Scholars in Pediatric Anesthesia Program (ViSiPAP): Developing tomorrow's pediatric anesthesia leaders.

Promoting and retaining junior faculty are major challenges for many medical schools. High clinical workloads often limit time for scholarly projects and academic development, especially in anesthesiology. To address this, we created the East/West Visiting Scholars in Pediatric Anesthesia Program (ViSiPAP). The program's goal is to help "jumpstart" academic careers by providing opportunities for national exposure and recognition through invited lectures and collaborative opportunities. East/West ViSiPAP benefits the participating scholars, the home and hosting anesthesia departments, and pediatric anesthesia fellowship training programs. By fostering a sense of well-being and inclusion in the pediatric anesthesia community, East/West ViSiPAP has the potential to increase job satisfaction, help faculty attain promotion, and reduce attrition. Faculty and trainees are exposed to new expertise and role models. Moreover, ViSiPAP provides opportunities for women and underrepresented in medicine faculty. This program can help develop today's junior faculty into tomorrow's leaders in pediatric anesthesia. We advocate for expanding the concept of ViSiPAP to other institutions in academic medicine.

Impaired cerebral autoregulation and elevation in plasma glial fibrillary acidic protein level during cardiopulmonary bypass surgery for CHD.

BACKGROUND: Cerebrovascular reactivity monitoring has been used to identify the lower limit of pressure autoregulation in adult patients with brain injury. We hypothesise that impaired cerebrovascular reactivity and time spent below the lower limit of autoregulation during cardiopulmonary bypass will result in hypoperfusion injuries to the brain detectable by elevation in serum glial fibrillary acidic protein level. METHODS: We designed a multicentre observational pilot study combining concurrent cerebrovascular reactivity and biomarker monitoring during cardiopulmonary bypass. All children undergoing bypass for CHD were eligible. Autoregulation was monitored with the haemoglobin volume index, a moving correlation coefficient between the mean arterial blood pressure and the near-infrared spectroscopy-based trend of cerebral blood volume. Both haemoglobin volume index and glial fibrillary acidic protein data were analysed by phases of bypass. Each patient's autoregulation curve was analysed to identify the lower limit of autoregulation and optimal arterial blood pressure. RESULTS: A total of 57 children had autoregulation and biomarker data for all phases of bypass. The mean baseline haemoglobin volume index was 0.084. Haemoglobin volume index increased with lowering of pressure with 82% demonstrating a lower limit of autoregulation (41±9 mmHg), whereas 100% demonstrated optimal blood pressure (48±11 mmHg). There was a significant association between an individual's peak autoregulation and biomarker values (p=0.01). CONCLUSIONS: Individual, dynamic non-invasive cerebrovascular reactivity monitoring demonstrated transient periods of impairment related to possible silent brain injury. The association between an impaired autoregulation burden and elevation in the serum brain biomarker may identify brain perfusion risk that could result in injury.

The Development and Implementation of Cognitive Aids for Critical Events in Pediatric Anesthesia: The Society for Pediatric Anesthesia Critical Events Checklists.

Cognitive aids such as checklists are commonly used in modern operating rooms for routine processes, and the use of such aids may be even more important during critical events. The Quality and Safety Committee of the Society for Pediatric Anesthesia (SPA) has developed a set of critical-event checklists and cognitive aids designed for 3 purposes: (1) as a repository of the latest evidence-based and expert opinion-based information to guide response and management of critical events, (2) as a source of just-in-time information during critical events, and (3) as a method to facilitate a shared understanding of required actions among team members during a critical event. Committee members, who represented children's hospitals from across the nation, used the recent literature and established guidelines (where available) and incorporated the expertise of colleagues at their institutions to develop these checklists, which included relevant factors to consider and steps to take in response to critical events. Human factors principles were incorporated to enhance checklist usability, facilitate error-free accomplishment, and ensure a common approach to checklist layout, formatting, structure, and design.The checklists were made available in multiple formats: a PDF version for easy printing, a mobile application, and at some institutions, a Web-based application using the anesthesia information management system. After the checklists were created, training commenced, and plans for validation were begun. User training is essential for successful implementation and should ideally include explanation of the organization of the checklists; familiarization of users with the layout, structure, and formatting of the checklists; coaching in how to use the checklists in a team environment; reviewing of the items; and simulation of checklist use. Because of the rare and unpredictable nature of critical events, clinical trials that use crisis checklists are difficult to conduct; however, recent and future simulation studies with adult checklists provide a promising avenue for future validation of the SPA checklists. This article will review the developmental steps in producing the SPA crisis checklists, including creation of content, incorporation of human factors elements, and validation in simulation. Critical-events checklists have the potential to improve patient care during emergency events, and it is hoped that incorporating the elements presented in this article will aid in successful implementation of these essential cognitive aids.

Interactive pediatric emergency checklists to the palm of your hand - How the Pedi Crisis App traveled around the world.

BACKGROUND: Cognitive aids help clinicians manage critical events and have been shown to improve outcomes by providing critical information at the point of care. Critical event guidelines, such as the Society of Pediatric Anesthesia's Critical Events Checklists described in this article, can be distributed globally via interactive smartphone apps. From October 1, 2013 to January 1, 2014, we performed an observational study to determine the global distribution and utilization patterns of the Pedi Crisis cognitive aid app that the Society for Pediatric Anesthesia developed. We analyzed distribution and utilization metrics of individuals using Pedi Crisis on iOS (Apple Inc., Cupertino, CA) devices worldwide. We used Google Analytics software (Google Inc., Mountain View, CA) to monitor users' app activity (eg, screen views, user sessions). METHODS: The primary outcome measurement was the number of user-sessions and geographic locations of Pedi Crisis user sessions. Each user was defined by the use of a unique Apple ID on an iOS device. RESULTS: Google Analytics correlates session activity with geographic location based on local Internet service provider logs. Pedi Crisis had 1 252 active users (both new and returning) and 4 140 sessions across 108 countries during the 3-month study period. Returning users used the app longer and viewed significantly more screens that new users (mean screen views: new users 1.3 [standard deviation +/-1.09, 95% confidence interval 1.22-1.55]; returning users 7.6 [standard deviation +/-4.19, 95% confidence interval 6.73-8.39]P<.01) CONCLUSIONS: Pedi Crisis was used worldwide within days of its release and sustained utilization beyond initial publication. The proliferation of handheld electronic devices provides a unique opportunity for professional societies to improve the worldwide dissemination of guidelines and evidence-based cognitive aids.

Perioperative hypothermia in neonatal intensive care unit patients: effectiveness of a thermoregulation intervention and associated risk factors.

BACKGROUND: Hypothermia in neonatal intensive care unit patients is associated with morbidity. Perioperative normothermia is the standard of care. AIMS: We hypothesized that a quality improvement intervention (transport protocol, transport education, ongoing monitoring) would decrease the incidence of perioperative hypothermia. Secondarily, we hypothesized that patients undergoing surgery at a postmenstrual age of <37 weeks or at a weight of <1.5 kg would be at higher risk for perioperative hypothermia. METHODS: Lean Six Sigma methodology was used to institute a quality improvement intervention. In a retrospective chart review, we identified 708 cases for which the neonatal intensive care unit was the preoperative and postoperative destination and documented patient characteristics, including postoperative temperature. Cardiac surgical cases and cases with no postoperative temperature record were excluded. RESULTS: Patients in the postintervention group had a statistically significant decrease in hypothermia compared to those in the preintervention group (P < 0.001; OR: 0.17; 95% CI: 0.09-0.31). The absolute risk of hypothermia was 23% in the preintervention group and 6% in the postintervention group. Weight <1.5 kg on day of surgery (P = 0.45; OR: 0.63; 95% CI: 0.16-2.24) and postmenstrual age (P = 0.91; OR: 1.07; 95% CI: 0.33-3.98) were not risk factors. Odds of hypothermia were increased in patients undergoing interventional cardiology procedures (P = 0.003; OR: 17.77; 95% CI: 2.07-125.7). CONCLUSIONS: Perioperative hypothermia is a challenge in the care of neonatal intensive care unit patients; however, a thermoregulation intervention can decrease the incidence with sustained results. Future studies can examine why certain procedures have a tendency toward increased perioperative hypothermia, determine the relative value of quality improvement interventions, and characterize the morbidity and mortality associated with perioperative hypothermia in neonatal intensive care unit patients.

Hemoglobin thresholds for transfusion in pediatric patients at a large academic health center.

BACKGROUND: Although prior studies support the use of a hemoglobin (Hb) transfusion trigger of 7 to 8 g/dL for most hospitalized adults, there are few studies in pediatric populations. We therefore investigated transfusion practices and Hb triggers in hospitalized children. STUDY DESIGN AND METHODS: We performed a historical cohort study comparing transfusion practices in hospitalized children by service within a single academic institution. Blood utilization data from transfused patients (n = 3370) were obtained from electronic records over 4 years. Hb triggers and posttransfusion Hb levels were defined as the lowest and last Hb measured during hospital stay, respectively, in transfused patients. The mean and percentile distribution for Hb triggers were compared to the evidence-based restrictive transfusion threshold of 7 g/dL. RESULTS: Mean Hb triggers were above the restrictive trigger (7 g/dL) for eight of 12 pediatric services. Among all of the services, there were significant differences between the mean Hb triggers (>2.5 g/dL, p<0.0001) and between the posttransfusion Hb levels (>3 g/dL, p < 0.0001). The variation between the 10th and 90th percentiles for triggers (up to 4 g/dL, p < 0.0001) and posttransfusion Hb levels (up to 6 g/dL, p < 0.0001) were significant. Depending on the service, between 25 and 90% of transfused patients had Hb triggers higher than the restrictive range. CONCLUSIONS: Red blood cell (RBC) transfusion therapy varies significantly in hospitalized children with mean Hb triggers above a restrictive threshold for most services. Our findings suggest that transfusions may be overused and that implementing a restrictive transfusion strategy could decrease the use of RBC transfusions, thereby reducing the associated risks and costs.

Pulmonary vascular resistance index and mortality after paediatric heart transplant.

BACKGROUND: Although some prior studies have provided evidence to question the historical belief that pulmonary vascular resistance index ⩾6 Wood Units×m2 should be a contraindication to heart transplantation in children, no national analyses specific to the modern area have addressed this question. METHODS: Data were analysed for paediatric heart transplant recipients from 1 January, 2002 to 1 September, 2012 (n=699). The relationship between pulmonary vascular resistance and all-cause 30-day mortality was evaluated using univariate and multivariate analyses. RESULTS: The 30-day mortality included 10 patients (1.43%), which is lower than in the previous analyses. Receiver operating curve analysis of pulmonary vascular resistance index as a predictor of mortality yielded a cut-off value of 3.37 Wood Units×m2, but the area under the curve and specificity of this threshold was weaker than in previous analyses. Whereas pulmonary vascular resistance index treated as a dichotomised variable was a significant predictor of mortality in univariate (odds ratio 4.92, 95% confidence interval 1.04-23.33, p=0.045) and multivariate (odds ratio 5.26, 95% confidence interval 1.07-25.80, p=0.041) analyses, pulmonary vascular resistance index treated as a continuous variable was not a significant predictor of mortality in univariate (p=0.12) or multivariate (p=0.11) analyses. CONCLUSIONS: The relationship between pulmonary vascular resistance and post-heart transplant mortality in children is less convincing in this analysis of a comprehensive, contemporary database than in previous series. This suggests the possibility that modern improvements in the management of post-transplant right ventricular dysfunction have mitigated the contribution of pulmonary hypertension to early mortality.

Transfusion-associated hyperkalemic cardiac arrest in pediatric patients receiving massive transfusion.

BACKGROUND: Hyperkalemic cardiac arrest is a potential complication of massive transfusion in children. Our objective was to identify risk factors and potential preventive measures by reviewing the literature on transfusion-associated hyperkalemic cardiac arrest (TAHCA) in the pediatric population. STUDY DESIGN AND METHODS: Literature searches were performed in MEDLINE and the Cochrane Database of Systematic Reviews. RESULTS: We identified nine case reports of pediatric patients who had experienced cardiac arrest during massive transfusion. Serum potassium concentration was reported in eight of those reports; the mean was 9.2 ± 1.8 mmol/L. Risk factors for TAHCA noted in the case reports included infancy (n = 6); age of red blood cells (RBCs; n = 5); site of transfusion (n = 5); and the presence of comorbidities such as hyperkalemia, hypocalcemia, acidemia, and hypotension (n = 9). We also identified 13 clinical studies that examined potassium levels associated with transfusion. Of those 13, five studied routine transfusion, two were registries, and six examined massive transfusion. CONCLUSIONS: Key points identified from this literature search are as follows: 1) Case reports are skewed toward infants and neonates in particular and 2) the rate of blood transfusion, more so than total volume, cardiac output, and the site of infusion, are key factors in the development of TAHCA. Measures to reduce the risk of TAHCA in young children include anticipating and replacing blood loss before significant hemodynamic compromise occurs, using larger-bore (>23-gauge) peripheral intravenous catheters rather than central venous access, checking and correcting electrolyte abnormalities frequently, and using fresher RBCs for massive transfusion.

National pediatric anesthesia safety quality improvement program in the United States.

BACKGROUND: As pediatric anesthesia has become safer over the years, it is difficult to quantify these safety advances at any 1 institution. Safety analytics (SA) and quality improvement (QI) are used to study and achieve high levels of safety in nonhealth care industries. We describe the development of a multiinstitutional program in the United States, known as Wake-Up Safe (WUS), to determine the rate of serious adverse events (SAE) in pediatric anesthesia and to apply SA and QI in the pediatric anesthesia departments to decrease the SAE rate. METHODS: QI was used to design and implement WUS in 2008. The key drivers in the design were an organizational structure; an information system for the SAE; SA to characterize the SAE; QI to imbed high-reliability care; communications to disseminate the learnings; and engaged leadership in each department. Interventions for the key drivers, included Participation Agreements, Patient Safety Organization designation, IRB approval, Data Management Co., membership fee, SAE standard templates, SA and QI workshops, and department leadership meetings. RESULTS: WUS has 19 institutions, 39 member anesthesiologists, 734 SAE, and 736,365 anesthetics as of March, 2013. The initial members joined at year 1, and initial SAE were recorded by year 2. The SAE rate is 1.4 per 1000 anesthetics. Of SAE, respiratory was most common, followed by cardiac arrest, care escalation, and cardiovascular, collectively 76% of SAE. In care escalation, medication errors and equipment dysfunction were 89%. Of member anesthesiologists, 70% were trained in SA and QI by March 2013; virtually, none had SA and QI expertise before joining WUS. CONCLUSION: WUS documented the incidence and types of SAE nationally in pediatric anesthesiology. Education and application of QI and SA in anesthesia departments are key strategies to improve perioperative safety by WUS.

Wake Up Safe and root cause analysis: quality improvement in pediatric anesthesia.

In 2006, the Quality and Safety Committee of the Society for Pediatric Anesthesia initiated a quality improvement project for the specialty of pediatric anesthesiology that ultimately resulted in the development of Wake Up Safe (WUS), a patient safety organization that maintains a registry of de-identified, serious adverse events. The ultimate goal of WUS is to implement change in processes of care that improve the quality and safety of anesthetic care provided to pediatric patients nationwide. Member institutions of WUS submit data regarding the types and numbers of anesthetics performed and information pertaining to serious adverse events. Before a member institution submits data for any serious adverse event, 3 anesthesiologists who were not involved in the event must analyze the event with a root cause analysis (RCA) to identify the causal factor(s). Because institutions across the country use many different RCA methods, WUS educated its members on RCA methods in an effort to standardize the analysis and evaluate each serious adverse event that is submitted. In this review, we summarize the background and development of this patient safety initiative, describe the standardized RCA method used by its members, demonstrate the use of this RCA method to analyze a serious event that was reported, and discuss the ways WUS plans to use the data to promote safer anesthetic practices for children.

Pediatric preoperative blood ordering: when is a type and screen or crossmatch really needed?

BACKGROUND: Unnecessary testing for and ordering of blood products adds to overall healthcare costs. OBJECTIVES: Determine intraoperative red blood cell (RBC) product utilization for pediatric procedures and costs associated with perioperative testing and ordering. METHODS: A retrospective chart review captured perioperative blood testing and intraoperative transfusion data for patients <19 years of age who underwent noncardiac surgery over a 13-month period at one tertiary care hospital. The main outcome measure was cost associated with testing for blood products in patients undergoing procedures that had a zero rate of transfusion. RESULTS: The intraoperative transfusion rate for 8620 noncardiac pediatric procedures was 2.78%. Of 8380 nontransfused patients, 707 (8.4%) had type and screen, and of those, 420 (5%) were crossmatched for RBC products in preparation for surgery. The 10 surgical procedures that had the highest perioperative blood testing but no instances of transfusion were as follows: colostomy or ileostomy takedown, spinal cord untethering, tunneled catheter placement, laparoscopic Nissen fundoplication, elbow reduction and fixation, lumbar puncture, suboccipital craniectomy, hip arthrogram, percutaneous intravascular central line, and tonsillectomy and adenoidectomy. Procedures with low transfusion probability and high crossmatch testing were ventriculoperitoneal shunt revision and growing rod distraction. For all nontransfused patients, the cost of obtaining type and screen was $31,815, and the cost for crossmatch was $25,200. CONCLUSION: Patients may undergo preoperative type and screen or crossmatch for procedures rarely associated with transfusion. Historic transfusion probability may be used to predict need for transfusion for specific surgical procedures and reduce unnecessary perioperative testing and associated costs.

Glial fibrillary acidic protein in children with congenital heart disease undergoing cardiopulmonary bypass.

OBJECTIVE: To determine whether blood levels of the brain-specific biomarker glial fibrillary acidic protein rise during cardiopulmonary bypass for repair of congenital heart disease. METHODS: This is a prospective observational pilot study to characterise the blood levels of glial fibrillary acidic protein during bypass. Children <21 years of age undergoing bypass for congenital heart disease at Johns Hopkins Hospital and Texas Children's Hospital were enrolled. Blood samples were collected during four phases: pre-bypass, cooling, re-warming, and post-bypass. RESULTS: A total of 85 patients were enrolled between October, 2010 and May, 2011. The median age was 0.73 years (range 0.01-17). The median weight was 7.14 kilograms (range 2.2-86.5). Single ventricle anatomy was present in 18 patients (22%). Median glial fibrillary acidic protein values by phase were: pre-bypass: 0 ng/ml (range 0-0.35); cooling: 0.039 (0-0.68); re-warming: 0.165 (0-2.29); and post-bypass: 0.112 (0-0.97). There were significant elevations from pre-bypass to all subsequent stages, with the greatest increase during re-warming (p = 0.0001). Maximal levels were significantly related to younger age (p = 0.03), bypass time (p = 0.03), cross-clamp time (p = 0.047), and temperature nadir (0.04). Peak levels did not vary significantly in those with single ventricle anatomy versus two ventricle repairs. CONCLUSION: There are significant increases in glial fibrillary acidic protein levels in children undergoing cardiopulmonary bypass for repair of congenital heart disease. The highest values were seen during the re-warming phase. Elevations are significantly associated with younger age, bypass and cross-clamp times, and temperature nadir. Owing to the fact that glial fibrillary acidic protein is the most brain-specific biomarker identified to date, it may act as a rapid diagnostic marker of brain injury during cardiac surgery.

Pediatric perioperative life support.

Pediatric advanced life support training and guidelines are typically designed for first-responders and out-of-hospital resuscitation. Guidelines and scenarios that are more applicable to the perioperative environment would be beneficial for anesthesiologists. The goal of this article is to review resuscitation of pediatric patients during the perioperative period. We use a format that focuses on preresuscitation preparation, resuscitation techniques, and postresuscitation management in the perioperative period. In an effort to provide information of maximum benefit to anesthesiologists, we include common pediatric perioperative arrest scenarios with detailed description of their management. We also provide a section on postresuscitation management and review the techniques for maintaining the child's hemodynamic and metabolic stability. Finally, 3 appendices are included: an example of an intraoperative arrest record that provides feedback for interventions; a table of key medications for pediatric perioperative resuscitation; and a review of defibrillator use and simulation exercises to promote effective defibrillation.
