ABSTRACT

BACKGROUND: The number of adolescents and adults identifying as trans or gender-diverse is increasing. The lesbian, gay, bisexual, transgender, queer, and "other" (LGBTQ+) population is recognized as a marginalized health care population. This retrospective study sought to investigate demographic trends in transgender and gender-diverse (TGD) youth accessing surgical care in the United States. METHODS: Using a multi-institutional dataset from the Pediatric Health Information System (PHIS), we described demographic and periprocedural data for TGD adolescents, ages 10 to 18 years, who underwent a surgical procedure between January 1, 2016 and August 31, 2022. RESULTS: Among 767,224 youth who underwent surgical procedures during the study period, 807 (0.1%, 95% confidence interval [CI], 0.09-0.11) were identified as TGD. The overall prevalence of identified TGD youth increased from 0.02% in 2016 to 0.23% in 2022. TGD youth were mostly (71%) assigned female at birth and 13 to 18 years of age (91%, 733/807) at the time of surgery. A total of 76% of TGD patients were non-Hispanic White, 62% had commercial insurance, and 49% lived in a ZIP code with a median annual income between $39,000 and $63,000. Of the 807 TGD patients identified, 264 (33%) were from the Northeast, 226 (28%) were from the Midwest, 219 (27%) were from the West, and 98 (12%) were from the South census regions. The most common procedures for TGD youth to undergo were breast reduction/augmentation (n = 135), insertion/removal of subcutaneous implant device (n = 98), and orthopedic procedures of the hip and lower extremity (n = 29). CONCLUSIONS: We reported the perioperative characteristics of TGD youth and showed a steady increase in the detected prevalence of TGD adolescents accessing surgical care. Future investigations into specific challenges associated with caring for these patients are warranted.

ABSTRACT

Anesthesiology is a medical specialty well known for its work in patient safety, allowing the field to show a dramatic decrease in perioperative morbidity and mortality in both adults and children since the 1950s. Currently, anesthesia-related mortality is close to zero in healthy children, with deaths occurring primarily in children ASA physical status ≥4. Survival during anesthesia today represents the expectation and standard of care, rather than a marker of quality. Several programs and organizations have created measures to assess safety in pediatric anesthesia-yet none are universally accepted as safety metrics or bundled to evaluate specific aspects of care. In addition, collection of this nonstandardized data in individual centers requires a significant investment of resources and personnel limiting access to only large, "resource-rich" institutions. In this perspective paper, we provide an overview of the efforts made to enhance quality of care across medical specialties with a specific emphasis on pediatric anesthesiology. We discuss the need for standardization of metrics to establish targets and benchmarks for the delivery of high-quality care to children and adolescents mainly in North America. The time has come to move beyond mortality and establish universally accepted minimum outcome standards in pediatric anesthesia. We believe this will ultimately improve confidence in the quality of pediatric anesthesia care offered to children, no matter where they are receiving that care.

ABSTRACT

BACKGROUND: Anaphylactic reactions to antigens in the perioperative environment are uncommon, but they have a potential to lead to serious morbidity and/or mortality. The incidence of anaphylactic reactions is 1:37 000 pediatric anesthetics, and substantially less than the 1:10 000 to 1:20 000 incidence in the adult population. Neuromuscular blocking agents, latex, and antibiotics are the most frequently cited triggers. To date, there is no comprehensive report on perioperative anaphylactic reactions in children in the United States. Using the Wake-up Safe database, we examined the incidence and consequences of reported perioperative anaphylaxis events. METHODS: We reviewed the Wake-up Safe database from 2010 to 2017 and identified all reported instances of anaphylaxis. The triggering agent, timing, and location of the registered event, severity of patient harm, and preventability were identified. Narrative review of free-text comments entered by reporting centers was performed to determine presenting symptoms, and interventions required. Type of case was identified from procedure codes provided in mandatory fields. RESULTS: Among 2 261 749 cases reported to the Wake-up Safe database during the study period, perioperative anaphylactic reactions occurred in 1:36 479 (0.003%). Antibiotics, neuromuscular blocking agents, and opioid analgesics were the main triggers. Forty-nine cases (79%) occurred in the operating room, and 13 cases (21%) occurred in off-site locations. Seven (11%) patients required cardiopulmonary resuscitation following the onset of symptoms. Thirty-five (57%) patients were treated with epinephrine or epinephrine plus other medications, whereas 5% were managed only with phenylephrine. Most cases (97%) required escalation of care after the event. Regarding case preventability, 91% of cases were marked as either "likely could not have been prevented" or "almost certainly could not have been prevented." CONCLUSION: The estimated incidence of anaphylaxis and inciting agents among the pediatric population in this study were consistent with the most recent published studies outside of the United States; however, new findings included need for cardiopulmonary resuscitation in 11% of cases, and estimated fatality of 1.6%. The management of perioperative anaphylaxis could be improved for some cases as epinephrine was not administered, or its administration was delayed. Fewer than half of reported cases had additional investigation to formally identify the responsible agent.

ABSTRACT

BACKGROUND: Perioperative aspiration, while rare, is a serious complication of anesthetic care. Consequences of aspiration may include physical obstruction, wheezing, and pneumonia, resulting in mild to severe hypoxemia and even death. AIM: We used a multi-institutional registry of pediatric patients to identify factors that influence the rate and resulting harm of perioperative pulmonary aspiration. METHODS: The Wake Up Safe registry was queried for all severe adverse events reported from 29 institutions from 2010 to 2017. Aspiration events were identified through the "respiratory adverse event" data entry form or through free text search. Multivariable regression was used to predict aspiration events, and contributory factors were identified by reviewing free text case comments. RESULTS: Analysis included 2 440 810 anesthetics administered involving patients ≤18 years of age. There were 135 pulmonary aspiration events, for an incidence of 0.006%. Within these 135 cases, 110 cases (82%) resulted in escalation of care and 51 (38%) resulted in patient harm, including 2 deaths (1.5%). In multivariable analysis, patients undergoing emergency surgery (OR 2.0 [1.2-3.5]) or with higher ASA status were more likely to experience aspiration (ASA 3 (OR 5.0 [2.6-9.1]); ASA ≥ 4 (OR 5.5 [3.8-16.8])). Noted causes of aspiration included gastrointestinal comorbid conditions (19%), postcoughing event or laryngospasm (14%), nil per os (NPO) violation (11%), blood or secretions in the airway following or during the procedure (6%), and oral premedication reaction (3%). CONCLUSION: Although infrequent, death was reported as a consequence of perioperative aspiration in two patients. The frequency with which NPO violations were identified as a potential cause of aspiration highlights the struggles institutions face with adherence to NPO regulations, as these cases may be preventable. Furthermore, preventive measures may be needed to address other common causes of aspiration, such as gastrointestinal comorbid conditions.

ABSTRACT

PURPOSE: Batten disease or neuronal ceroid lipofuscinosis is the most prevalent neurodegenerative disorder of childhood. Previously reported perioperative complications in children with Batten disease have come mainly from single case reports. The primary aim of the current study was to investigate perioperative complications of patients with Batten disease in the largest cohort known to date. The secondary objective was to characterize the anesthetic management including the use of propofol and to assess its association with adverse events. METHOD: We conducted a single center, retrospective descriptive study by querying the hospital's electronic medical record to identify patients with a diagnosis of Batten disease or ICD10 E75.4 who received anesthetic care from December 2014 to May 2019. RESULTS: Thirty-five patients who underwent a total of 93 anesthetic encounters (range 1-11) were included in the analysis. A total of 29 adverse events were identified. Hypotension (N = 6, 6.5%) and bradycardia (N = 7, 7.5%) requiring treatment with medications were the most common adverse events. Other adverse events include oxygen desaturation (N = 4, 4.3%), seizures (N = 4, 4.3%), unanticipated hospital or ICU admission (N = 1, 1.1%), PACU phase 1 stay > 120 min (N = 2, 2.2%), hypothermia (N = 4, 4.3%), agitation (N = 1, 1.1%), and laryngospasm requiring treatment (N = 1, 1.1%). The number of preoperative anti-epileptic drugs (AEDs) had a positive correlation with the rate of perioperative adverse events. There was no statistical relationship of adverse events with intraoperative use of propofol (odds ratio 1.03, 95% CI 0.42-2.51). CONCLUSIONS: The majority of these patients were managed without clinically significant perioperative complications. As previously reported, bradycardia, hypotension, and hypothermia were the most common adverse events. Routine avoidance of propofol in patients with Batten disease does not appear warranted.

ABSTRACT

BACKGROUND: Anesthesia services are frequently provided outside of the traditional operating room environment for children. It is unclear if adverse events which occur in off-site anesthetizing locations result in more severe outcomes compared to events in traditional operating rooms. AIM: We used a multi-institutional registry of pediatric patients to compare outcomes of perioperative adverse events between location types. METHODS: De-identified data from 24 pediatric tertiary care hospitals participating in the Wake Up Safe registry during 2010-2015 were analyzed. Peri-procedural adverse events occurring in operating rooms or off-site locations were included. The primary outcome was whether the adverse event was severe, defined as requiring escalation of care or resulting in temporary or significant harm. Multivariable logistic regression was used to compare location type (operating room vs. off-site) and the likelihood of a severe outcome among reported events. RESULTS: There were 1594 adverse events, of which 362 were associated with off-site anesthetizing locations. In multivariable logistic regression, off-site location was associated with greater odds of severe adverse event outcome (adjusted odds ratio, 1.31; 95% confidence interval: 1.01, 1.69; P = 0.044). Comparing adverse events in cardiac catheterization suites to events in operating rooms confirmed higher odds of severe outcome in the former group (adjusted odds ratio = 1.48; 95% confidence interval: 1.05, 2.08; P = 0.025), while this difference was not found for other off-site locations. CONCLUSION: Multivariable analysis of a large registry revealed a greater likelihood of severe outcome for adverse events occurring in cardiac catheterization suites (but not other out of the OR sites), compared to adverse events occurring in the operating room. Additional prospective studies are needed which better control for patient and environmental characteristics and their effect on severe outcomes after anesthesia.

ABSTRACT

Objectives This study classified patterns of discontinuous health insurance coverage, including change in coverage type and gaps in coverage, and described their associations with children's access to health care. Methods Using the 2011-2013 National Health Interview Survey data, we determined children's insurance coverage over the past year, and whether children had a usual source of care, had to delay getting care, or had unmet health care needs. Using multivariable logistic regression, we compared measures of access to care across insurance coverage patterns, classified as continuous private coverage; continuous public coverage; continuous lack of coverage; change in coverage type (public versus private) without gaps in coverage; and any gap in coverage. A subgroup analysis repeated this comparison for children with a caregiver-reported chronic physical illness. Results The analysis included 34,105 children, of whom 7% had a gap in coverage and 1% had a change in coverage type. On multivariable analysis, gaps in coverage were associated with increased likelihood of unmet health care needs, compared to continuous private (OR 6.9; 95% CI 5.9, 8.0) or continuous public coverage (OR 5.1; 95% CI 4.4, 6.0). Seamless changes in coverage were also associated with greater likelihood of unmet health care needs [OR vs. private: 3.8 (95% CI 2.3, 6.1); OR vs. public: 2.8 (95% CI 1.8, 4.6); all p < 0.001]. Results were similar for other study outcomes, and among children with chronic physical illness. Conclusions for Practice Both gaps in coverage and seamless changes between coverage types were associated with limited health care access for children.

ABSTRACT

PURPOSE: We prospectively investigated contamination of high-contact surfaces in the operating room (OR) using adenosine triphosphate (ATP) monitoring. We tested whether contamination would increase from morning (AM) to afternoon (PM), despite cleaning between cases. Second, we compared the degree of OR contamination to non-OR control sites. METHODS: ORs with high case volumes were selected for the study. Ten sites in each OR were swabbed using the AccuPoint® HC ATP Sanitation Monitoring device, which provided a numerical measure of contamination (relative light units, RLUs). According to the manufacturer, surfaces are considered clean at ≤ 400 RLUs. AM measurements were taken before the start of surgical cases and PM measurements were taken after cases were completed. RESULTS: Eighty morning and 70 afternoon samples were obtained from 8 ORs. Apart from the OR floor, laryngoscope handles had the highest level of morning contamination (1204 RLUs, interquartile range 345, 2603), with 75% of AM samples and 100% of PM samples exceeding 400 RLUs. This contamination was comparable to hospital toilet seats (87% of samples exceeding 400 RLUs). No sites showed statistically significant increases in contamination from AM to PM. CONCLUSION: Apart from the OR floors, laryngoscope handles emerged as a key OR site where improved cleaning practices may reduce cross-contamination risk. While some sites showed increased contamination over the course of the day, none of these met statistical significance thereby offering tentative evidence that current cleaning practices during case turnover are effective for most sites.

ABSTRACT

Bollgard(®) III was developed by combining cotton events COT102 and MON 15985 through conventional breeding to improve efficacy against lepidopteran feeding damage. COT102 produces the Vip3Aa19 protein and MON 15985 produces the Cry1Ac and Cry2Ab2 proteins. COT102 × MON 15985 has also been bred with Roundup Ready Flex(®) cotton (MON 88913) that confers glyphosate tolerance. This study evaluated the activity of COT102 and MON 15985 and the combined activity of COT102 and MON 15985 against the cotton bollworm (CBW, Helicoverpa zea). COT102, MON 15985, COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 have comparable Vip3Aa19 and/or Cry1Ac, Cry2Ab2 protein expression levels as determined by enzyme-linked immunosorbent assay. CBW demonstrated concentration-dependent growth inhibition after 7-days of feeding on lyophilized leaf tissue derived from COT102, MON 15985, COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 incorporated into an artificial diet. Observed EC50 values for COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 were comparable (≤4% deviation) with the predicted EC50 value under the assumption of additivity using the combined activity of COT102 and MON 15985. No interaction in biological activity between COT102 and MON 15985 is consistent with results from competition and ligand blotting assays that demonstrated that Vip3Aa does not inhibit the binding of either Cry1Ac or Cry2Ab2 and vice versa. The results from this study demonstrate that the activity of COT102 × MON 15985 against CBW is consistent with predictions of additivity.

ABSTRACT

MON 87411 maize, which expresses DvSnf7 RNA, was developed to provide an additional mode of action to confer protection against corn rootworm (Diabrotica spp.). A critical step in the registration of a genetically engineered crop with an insecticidal trait is performing an ecological risk assessment to evaluate the potential for adverse ecological effects. For MON 87411, an assessment plan was developed that met specific protection goals by characterizing the routes and levels of exposure, and testing representative functional taxa that would be directly or indirectly exposed in the environment. The potential for toxicity of DvSnf7 RNA was evaluated with a harmonized battery of non-target organisms (NTOs) that included invertebrate predators, parasitoids, pollinators, soil biota as well as aquatic and terrestrial vertebrate species. Laboratory tests evaluated ecologically relevant endpoints such as survival, growth, development, and reproduction and were of sufficient duration to assess the potential for adverse effects. No adverse effects were observed with any species tested at, or above, the maximum expected environmental concentration (MEEC). All margins of exposure for NTOs were >10-fold the MEEC. Therefore, it is reasonable to conclude that exposure to DvSnf7 RNA, both directly and indirectly, is safe for NTOs at the expected field exposure levels.

ABSTRACT

INTRODUCTION: The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care. METHODS: We performed a retrospective review of the Quality Improvement database from the Department of Anesthesiology & Pain Medicine at Nationwide Children's Hospital. The database was searched to identify those patients who had a RRT evaluation activated within 24 h of receiving anesthesia or procedural sedation. These patients' charts were reviewed to obtain demographic information, etiology of the RRT call, and outcomes. RESULTS: The study cohort included 106 RRT calls that were made over a 3-year period. Six patients were excluded from analysis due to incomplete datasets. One hundred patients remained for analysis including 60 males and 40 females. Patients ranged in age from 0.08 to 31.21 years (7.8 ± 7.7 years, median 5.3 years). Seventy-one patients were American Society of Anesthesiologists' (ASA) status 3 or 4 and 29 patients were ASA status 1 or 2. Five calls were made for patients who had undergone procedural sedation while the other 95 were on patients who received general anesthesia. The average time to the RRT call after the end of anesthetic care was 11.4 ± 6.6 h. Respiratory concern was the most common reason for RRT initiation, accounting for 71 of the 100 calls. Forty-nine patients had a recent respiratory illness, chronic respiratory-related disease, or history of preterm birth. Fifty patients (50%) were transferred to a higher level of care following the RRT consult. There was no significant difference between age, gender, ASA status, or etiology of the event for patients transferred vs. those who were not. A significant difference was noted in the Pediatric Early Warning Score of patients transferred to a higher level of care in comparison to patients who remained on the floor (4 ± 2 vs. 3 ± 2, P = 0.0097). CONCLUSION: RRT calls were most common for respiratory concerns. High ASA status, general anesthesia administration, and the presence of acute or chronic conditions prior to anesthetic administration predispose a patient to perioperative complications resulting in the need for an RRT call.

ABSTRACT

A biotechnology-derived corn variety, MON 87411, containing a suppression cassette that expresses an inverted repeat sequence that matches the sequence of western corn rootworm (WCR; Diabrotica virgifera virgifera) has been developed. The expression of the cassette results in the formation of a double-stranded RNA (dsRNA) transcript containing a 240 bp fragment of the WCR Snf7 gene (DvSnf7) that confers resistance to corn rootworm by suppressing levels of DvSnf7 mRNA in WCR after root feeding. Internationally accepted guidelines for the assessment of genetically modified crop products have been developed to ensure that these plants are as safe for food, feed, and environmental release as their non-modified counterparts (Codex, 2009). As part of these assessments MON 87411 must undergo an extensive environmental assessment that requires large quantities of DvSnf7 dsRNA that was produced by in vitro transcription (IVT). To determine if the IVT dsRNA is a suitable surrogate for the MON 87411-produced DvSnf7 dsRNA in regulatory studies, the nucleotide sequence, secondary structure, and functional activity of each were characterized and demonstrated to be comparable. This comprehensive characterization indicates that the IVT DvSnf7 dsRNA is equivalent to the MON 87411-produced DvSnf7 dsRNA and it is a suitable surrogate for regulatory studies.

ABSTRACT

The sequence specificity of the endogenous RNA interference pathway allows targeted suppression of genes essential for insect survival and enables the development of durable and efficacious insecticidal products having a low likelihood to adversely impact non-target organisms. The spectrum of insecticidal activity of a 240 nucleotide (nt) dsRNA targeting the Snf7 ortholog in Western Corn Rootworm (WCR; Diabrotica virgifera virgifera) was characterized by selecting and testing insects based upon their phylogenetic relatedness to WCR. Insect species, representing 10 families and 4 Orders, were evaluated in subchronic or chronic diet bioassays that measured potential lethal and sublethal effects. When a specific species could not be tested in diet bioassays, the ortholog to the WCR Snf7 gene (DvSnf7) was cloned and corresponding dsRNAs were tested against WCR and Colorado potato beetle (Leptinotarsa decemlineata); model systems known to be sensitive to ingested dsRNA. Bioassay results demonstrate that the spectrum of activity for DvSnf7 is narrow and activity is only evident in a subset of beetles within the Galerucinae subfamily of Chrysomelidae (>90% identity with WCR Snf7 240 nt). This approach allowed for evaluating the relationship between minimum shared nt sequence length and activity. A shared sequence length of ≥ 21 nt was required for efficacy against WCR (containing 221 potential 21-nt matches) and all active orthologs contained at least three 21 nt matches. These results also suggest that WCR resistance to DvSnf7 dsRNA due to single nucleotide polymorphisms in the target sequence of 240 nt is highly unlikely.

ABSTRACT

OBJECTIVES: The aim of our investigation was to establish normal pediatric reference intervals (PRIs) for rotational thromboelastometry (ROTEM) Delta assays in a representative group of healthy children, 0 to 18 years of age, at our institution. METHODS: This was a prospective study of healthy pediatric patients undergoing elective minor surgery requiring placement of an intravenous cannula. The sample size for patients was 20 per age group of either sex from 5 different age groups based on coagulation system maturity: 0 to 6 or fewer months, more than 6 to 12 or fewer months, more than 1 year to 5 or fewer years, more than 5 to 11 or fewer years, and more than 11 to 18 or fewer years. ROTEM Delta assays assessed include the EXTEM, INTEM, and FIBTEM. RESULTS: We defined 2 sets of ROTEM PRIs for our patient population: one for patients 11 years or younger and one for children more than 11 years of age. For those 11 years or younger, the PRIs were derived from the 2.5th and 97.5th percentiles from the 0 to 11 age groups. For those older than 11 years, previously published adult reference intervals validated internally with adult normal samples were used. CONCLUSIONS: The 2 sets of PRIs were embedded into our electronic medical record, allowing clinicians to easily interpret their patient's ROTEM results against age-verified reference ranges, enabling them to make informed transfusion decisions.

ABSTRACT

PURPOSE: To review experience with outpatient spinal anesthesia (SA) from a single center in infants ≤6 months of age. METHODS: Retrospective review of all SAs performed in the ambulatory setting in the outpatient surgery centers in infants ≤6 months of age from 2016 to 2020, focusing on success rate, adverse events, post-anesthesia care unit (PACU) times, and emergency department (ED) or urgent care (UC) returns within 7 days of the operation. RESULTS: The study cohort included 175 SAs performed on 173 patients ≤6 months of age. One hundred and sixty-two patients (93%) were able to undergo their respective surgical procedures under SA without conversion to general anesthesia. One hundred and thirty-six patients (78%) did not require additional sedation or analgesic agents. The median time from entering the operating room until the start of surgical procedure was 17 min. One hundred and twenty-six patients (72%) were able to bypass Phase I of the PACU. One hundred and forty-seven patients (86%) were discharged in less than two hours postoperatively. Only one complication related to SA was noted. This was a patient who returned on postoperative day 2 with a possible CSF leak noted by ultrasound. After overnight hospital floor admission, he was discharged the next day after receiving intravenous fluids without further sequelae. CONCLUSIONS: SA is a viable option for anesthetic care in infants ≤6 months of age presenting for outpatient surgery. Advantages included the ability to bypass PACU Phase I and facilitation of hospital discharge. LEVEL OF EVIDENCE: IV. Retrospective cohort treatment study.

ABSTRACT

AAP guidelines recommend infants less than 6 months of age are monitored for at least 2 hours following surgery. This retrospective study evaluated if adherence to the 2-hour monitoring guideline decreased the risk of adverse events associated with ambulatory procedures in infants younger than 6 months. Methods: We queried the hospital's electronic medical record to identify patients younger than 6 months of age who received anesthetic care from January 2015 to March 2020. Demographic data, intraoperative adverse events, and returns to the emergency department (ED) or urgent care within 7 days were captured for each patient. We calculated the number and frequency for categorical data and median and interquartile range (IQR) for continuous data. Chi-square or Fisher's exact test were used to compare patients who experienced an adverse event to those that did not. Results: One thousand one hundred seventy-seven patients who had 1,261 unique anesthetic encounters were analyzed. Forty-four adverse events were identified, 20 (1.6%) before discharge, including 3 unplanned admissions, and 24 (1.9%) returns to the ED/UC within 7 days postoperatively. We did not observe differences in postoperative recovery time in patients who experienced an adverse event and those who did not (88 min vs. 77 min, respectively, P = 0.078). None of the ED/UC returns would have been avoided by a longer PACU stay. Conclusions: With the appropriate patient selection, once physiological discharge readiness is met, adherence to a strict 2-hour time-based discharge criteria does not increase safety for infants younger than 6 months of age after ambulatory procedures.

ABSTRACT

BACKGROUND: Epidural anesthesia in infants undergoing open abdominal surgery has the potential to reduce opioid consumption, lower pain scores, and expedite tracheal extubation. We evaluated associations between use of continuous epidural chloroprocaine and improved intra- and post-operative outcomes. METHODS: This matched retrospective cohort study first identified 24 patients who between April 2018 through December 2019 were treated with a caudal catheter and epidural chloroprocaine infusion for a laparotomy at postnatal age of 6 months or less. A matched comparator group of 24 patients was derived based on age and type of surgery. Exclusion criteria were the presence of a preoperative opioid infusion, comorbidities that would preclude appropriate pain assessment, or a recent surgical procedure. Primary outcomes included opioid consumption and pain scores; we secondarily analyzed intraoperative anesthetic requirements, other systemic analgesic use, vital signs, tracheal extubation time, and procedural times. RESULTS: Treatment with epidural anesthesia was associated with lower 5-day total postoperative opioid consumption (3.2 mg/kg vs. 19.7 mg/kg in the respective epidural vs. systemic groups, p = 0.001) and time to tracheal extubation (1.3 days vs. 3.2 days, p = 0.005). Any statistically significant differences in pain scores were not clinically meaningful. There were no differences in mean arterial pressure or intraoperative inhaled anesthetic doses. CONCLUSION: Continuous infusion of epidural chloroprocaine in infants following open abdominal surgery may limit exposure to systemic opioid medications while providing adequate postoperative analgesia and shortening time to tracheal extubation.

ABSTRACT

OBJECTIVES: General anesthesia or sedation can facilitate the completion of diagnostic radiological studies in children. We evaluated the incidence, predictors, and causes of adverse events (AEs) when general anesthesia is provided for diagnostic radiological imaging. METHODS: Deidentified data from 24 pediatric tertiary care hospitals participating in the Wake-Up Safe registry during 2010-2015 were obtained for analysis. Children 18 years or younger receiving general anesthesia for radiological procedures were identified using Current Procedural Terminology codes, and reported AEs were analyzed if they were associated with anesthetic care at magnetic resonance imaging or computed tomography locations. Logistic regression was used to determine predictors of AE occurrence in cases with complete covariate data. RESULTS: We identified 175,486 anesthetics for diagnostic radiological exams, compared with 83 AEs in magnetic resonance imaging or computed tomography locations (AE incidence of 0.05%). In multivariable analysis, AEs were more likely among patients with American Society of Anesthesiologists physical status IV compared with American Society of Anesthesiologists physical status I patients (adjusted odds ratio, 8.9; 95% confidence interval, 2.8-28.0; P < 0.001). Twenty-three AEs resulted in harm to the patient, whereas 32 AEs required unplanned hospital or intensive care unit admission. Anesthetic complications or issues were the most common cause of AEs (n = 52). CONCLUSIONS: Anesthesia provided for pediatric radiological studies is very safe and with an overall low AE incidence. The contribution of anesthetic complications to reported AEs suggests opportunities for further process improvement in this setting.

ABSTRACT

BACKGROUND: That African American (AA) patients have poorer surgical outcomes compared with their white peers is established. The prevailing presumption is that these disparities operate within the context of a higher preoperative comorbidity burden among AA patients. Whether these racial differences in outcomes exist among apparently healthy children (traditionally expected to have low risk of postsurgical complications) has not been previously investigated. METHODS: We performed a retrospective study by analyzing the National Surgical Quality Improvement Program-Pediatric database from 2012 through 2017 and identifying children who underwent inpatient operations and were assigned American Society of Anesthesiologists physical status 1 or 2. We used univariable and risk-adjusted logistic regression to estimate the odds ratios and their 95% confidence intervals (CIs) of postsurgical outcomes comparing AA to white children. RESULTS: Among 172 549 apparently healthy children, the incidence of 30-day mortality, postoperative complications, and serious adverse events were 0.02%, 13.9%, and 5.7%, respectively. Compared with their white peers, AA children had 3.43 times the odds of dying within 30 days after surgery (odds ratio: 3.43; 95% CI: 1.73-6.79). Compared with being white, AA had 18% relative greater odds of developing postoperative complications (odds ratio: 1.18; 95% CI: 1.13-1.23) and 7% relative higher odds of developing serious adverse events (odds ratio: 1.07; 95% CI: 1.01-1.14). CONCLUSIONS: Even among apparently healthy children, being AA is strongly associated with a higher risk of postoperative complications and mortality. Mechanisms underlying the established racial differences in postoperative outcomes may not be fully explained by the racial variation in preoperative comorbidity.

ABSTRACT

This study evaluated progress to publication of pediatric quality improvement (QI) projects initially presented as national conference abstracts, according to project findings and other characteristics. QI abstracts were identified among presentations at the 2010-2015 American Academy of Pediatrics National Conference & Exhibition, and publications were tracked through June 2018. Positive findings (improvement on at least 1 quantitative project outcome), interventions, and analyses were correlated with journal publication. Of 142 abstracts, 128 (90%) reported positive findings. Forty-nine positive abstracts and 3 abstracts reporting negative results resulted in publication (38% vs 21%, respectively; P = .256). Median time to publication was 1.2 years for projects with positive findings, compared to >3 years for abstracts with negative findings (P = .029). Ninety percent of abstracts reported positive findings, and these abstracts progressed to publication more quickly. Overcoming publication bias for pediatric QI projects may enhance selection of promising interventions as new projects are designed.
