RESUMEN
OBJECTIVE: The use of telemedicine has increased and may enhance the care of children during medical transport. We aimed to evaluate the feasibility of synchronous telemedicine connectivity before interfacility transport of critically ill children by a pediatric transport team. METHODS: We performed a prospective, observational feasibility study of the introduction of synchronous telemedicine into an established pediatric transport team from 2019 to 2020. The outcomes examined included connectivity, physician workload, transport team satisfaction, and patient care outcomes. RESULTS: Among 118 eligible transports, telemedicine was considered in 23 transports (19%), including 11 transports in which an attempt to connect was sought and 12 in which telemedicine activation was offered but not attempted. The median connection time was 2.9 minutes (interquartile range, 1.7-4.4 minutes), and clinical care was altered in 1 case. Connection failed in 2 cases (18.2%). In 50% of cases, concurrent medical control physician workload prevented activation. There were no perceived benefits in 41.7% of cases. Team members indicated the desire for future telemedicine use in only 54.6% of cases. CONCLUSIONS: We found low utilization of synchronous telemedicine in interfacility pediatric transport. The identified barriers included reliable connectivity, physician workload, and low perceived benefit. Lessons learned and future research suggestions are presented to mitigate these barriers.

BACKGROUND: Perioperative arterial cannulation in children is routinely performed. Based on clinical observation of several complications related to femoral arterial lines, the authors performed a larger study to further examine complications. The authors aimed to (1) describe the use patterns and incidence of major short-term complications associated with arterial cannulation for perioperative monitoring in children, and (2) describe the rates of major complications by anatomical site and age category of the patient. METHODS: The authors examined a retrospective cohort of pediatric patients (age less than 18 yr) undergoing surgical procedures at a single academic medical center from January 1, 2006 to August 15, 2016. Institutional databases containing anesthetic care, arterial cannulation, and postoperative complications information were queried to identify vascular, neurologic, and infectious short term complications within 30 days of arterial cannulation. RESULTS: There were 5,142 arterial cannulations performed in 4,178 patients. The most common sites for arterial cannulation were the radial (N = 3,395 [66.0%]) and femoral arteries (N = 1,528 [29.7%]). There were 11 major complications: 8 vascular and 3 infections (overall incidence, 0.2%; rate, 2 per 1,000 lines; 95% CI, 1 to 4) and all of these complications were associated with femoral arterial lines in children younger than 5 yr old (0.7%; rate, 7 per 1,000 lines; 95% CI, 4 to 13). The majority of femoral lines were placed for cardiac procedures (91%). Infants and neonates had the greatest complication rates (16 and 11 per 1,000 lines, respectively; 95% CI, 7 to 34 and 3 to 39, respectively). CONCLUSIONS: The overall major complication rate of arterial cannulation for monitoring purposes in children is low (0.2%). All complications occurred in femoral arterial lines in children younger than 5 yr of age, with the greatest complication rates in infants and neonates. There were no complications in distal arterial cannulation sites, including more than 3,000 radial cannulations.

BACKGROUND: The potential adverse effects of exposures to general anesthesia on the developing human brain remain controversial. It has been hypothesized that hypotension accompanying anesthesia could be contributory. We hypothesized that among children exposed to multiple anesthetics prior to age 3, children developing adverse neurodevelopmental outcomes would be more likely to have intraoperative hypotension. METHODS: Two previously published study cohorts were utilized for analysis: the retrospective and prospective Mayo Anesthesia Safety in Kids cohorts. The two lowest consecutive systolic blood pressure measurements were abstracted and standardized by calculating a z-score for noninvasive blood pressure reference ranges for children. The lowest systolic blood pressure z-score (continuous variable) and intraoperative hypotension (lowest systolic blood pressure z-score <-1.0) were used to assess the association of intraoperative hypotension with the incidence of learning disabilities or attention-deficit/hyperactivity disorder(retrospective cohort) and factor scores/cluster membership (prospective cohort). RESULTS: One hunderd and sixteen and 206 children with multiple exposures to general anesthesia were analyzed in the retrospective and prospective cohorts with mean lowest systolic blood pressure z-scores -0.26 (SD 1.02) and -0.62 (SD 1.10), respectively. There was no overall association of the lowest z-score or hypotension with learning disabilities or attention-deficit/hyperactivity disorder in the retrospective cohort. In the prospective cohort, there was no overall association of the lowest systolic blood pressure or hypotension with factor scores or cluster membership. CONCLUSIONS: We did not find evidence to support the hypothesis that, among children exposed to multiple anesthetics prior to age 3, children developing adverse neurodevelopmental outcomes would be more likely to have intraoperative hypotension compared with those who did not.

BACKGROUND: The use of cognitive aids, such as emergency manuals (EMs), improves team performance on critical steps during crisis events. In our large academic anesthesia practice, we sought to broadly implement an EM and subsequently evaluate team member performance on critical steps. METHODS: We observed the phases of implementing an EM at a large academic anesthesia practice from 2013 to 2016, including the formation of the EM implementation team, identification of preferred EM characteristics, consideration of institution-specific factors, selection of the preferred EM, recognition of logistical barriers, and staff education. Utilization of the EM was tested in a regular clinical environment with all available resources using a standardized verbal simulation of 3 crisis events both preimplementation and 6 months postimplementation. Individual members of the anesthesia team were asked to verbalize interventions for specific crisis events over 60 seconds. RESULTS: We introduced a customized version of the Stanford Emergency Manual on January 26, 2015. Fifty-nine total participants (equal proportion of anesthesiology attending physicians, resident physicians, certified registered nurse anesthetists, and student registered nurse anesthetist staff) were surveyed in the preimplementation phase and 60 in the 6-month postimplementation phase. In the postimplementation phase, a minority (41.7%) utilized the EM for the verbal-simulated crisis events. Those who used the EM performed better than those who did not (median 21.0 critical steps out of a possible 30 total steps [70.0%], interquartile range 19-25 vs 18.0 critical steps verbalized [60.0%], interquartile range 16-20; P < .001). Among all subjects, the median number of critical steps verbalized was 16 (53.3%) preimplementation and 19.5 critical steps (65.0%) postimplementation. CONCLUSIONS: Implementation of an EM in a large academic anesthesia practice is not without challenges. While full integration of the EM was not achieved 6 months after implementation, verbalization of critical steps on 3 simulated crisis events improved when the EM was utilized.

BACKGROUND: Few studies of how exposure of children to anesthesia may affect neurodevelopment employ comprehensive neuropsychological assessments. This study tested the hypothesis that exposure to multiple, but not single, procedures requiring anesthesia before age 3 yr is associated with adverse neurodevelopmental outcomes. METHODS: Unexposed, singly exposed, and multiply exposed children born in Olmsted County, Minnesota, from 1994 to 2007 were sampled using a propensity-guided approach and underwent neuropsychological testing at ages 8 to 12 or 15 to 20 yr. The primary outcome was the Full-Scale intelligence quotient standard score of the Wechsler Abbreviated Scale of Intelligence. Secondary outcomes included individual domains from a comprehensive neuropsychological assessment and parent reports. RESULTS: In total, 997 children completed testing (411, 380, and 206 unexposed, singly exposed, and multiply exposed, respectively). The primary outcome of intelligence quotient did not differ significantly according to exposure status; multiply exposed and singly exposed children scoring 1.3 points (95% CI, -3.8 to 1.2; P = 0.32) and 0.5 points (95% CI, -2.8 to 1.9; P = 0.70) lower than unexposed children, respectively. For secondary outcomes, processing speed and fine motor abilities were decreased in multiply but not singly exposed children; other domains did not differ. The parents of multiply exposed children reported increased problems related to executive function, behavior, and reading. CONCLUSIONS: Anesthesia exposure before age 3 yr was not associated with deficits in the primary outcome of general intelligence. Although secondary outcomes must be interpreted cautiously, they suggest the hypothesis that multiple, but not single, exposures are associated with a pattern of changes in specific neuropsychological domains that is associated with behavioral and learning difficulties.

BACKGROUND: Utilization of general anesthesia in children has important policy, economic, and healthcare delivery implications, yet there is little information regarding the epidemiology of these procedures in the United States. AIMS: The primary objective of this study was to describe in a geographically defined population the incidence of procedures requiring general anesthesia up to the child's third birthday, and the patient characteristics associated with receiving these procedures. A secondary objective was to determine the proportion of children in the population who meet the risk criteria promulgated by the Food and Drug Administration (FDA). METHODS: A retrospective cohort of children born from 1994 to 2007 in Olmsted County, MN was established. Birth certificate information and receipt of general anesthesia before age 3 were collected. Proportional hazard regressions were performed to evaluate the association between characteristics of children and incidence of general anesthesia. RESULTS: Among the 20 922 children in the cohort, 3120 (14.9%) underwent at least 1 general anesthesia before age 3. In multivariate regression, factors independently associated with receiving at least 1 procedure included prematurity, male sex, lower birth weight, cesarean delivery, a non-Hispanic mother, and a White mother, controlling for multiple gestation, number of children previously born, age, education, and marital status of the mother. Seven hundred and twenty-three children (3.5%) had at least 1 subsequent procedure. Estimated gestational age <32 weeks and low birth weight were independently associated with receiving repeated anesthesia. Eight hundred and twenty children (3.9%) had a single prolonged exposure above 3 hours, multiple exposures prior to age 3, or both. CONCLUSION: Approximately 1 in 7 children were exposed to at least 1 episode of general anesthesia before age 3, and approximately 1 in 4 children who received general anesthesia fall within the high-risk category as defined by the recent FDA warning. The apparent disparities in surgical utilization related to race and ethnicity in this study population deserve further exploration.

BACKGROUND: Exposure of young animals to general anesthesia causes neurodegeneration and lasting behavioral abnormalities; whether these findings translate to children remains unclear. This study used a population-based birth cohort to test the hypothesis that multiple, but not single, exposures to procedures requiring general anesthesia before age 3 yr are associated with adverse neurodevelopmental outcomes. METHODS: A retrospective study cohort was assembled from children born in Olmsted County, Minnesota, from 1996 to 2000 (inclusive). Propensity matching selected children exposed and not exposed to general anesthesia before age 3 yr. Outcomes ascertained via medical and school records included learning disabilities, attention-deficit/hyperactivity disorder, and group-administered ability and achievement tests. Analysis methods included proportional hazard regression models and mixed linear models. RESULTS: For the 116 multiply exposed, 457 singly exposed, and 463 unexposed children analyzed, multiple, but not single, exposures were associated with an increased frequency of both learning disabilities and attention-deficit/hyperactivity disorder (hazard ratio for learning disabilities = 2.17 [95% CI, 1.32 to 3.59], unexposed as reference). Multiple exposures were associated with decreases in both cognitive ability and academic achievement. Single exposures were associated with modest decreases in reading and language achievement but not cognitive ability. CONCLUSIONS: These findings in children anesthetized with modern techniques largely confirm those found in an older birth cohort and provide additional evidence that children with multiple exposures are more likely to develop adverse outcomes related to learning and attention. Although a robust association was observed, these data do not determine whether anesthesia per se is causal.

BACKGROUND: Arthrogryposis syndromes are a heterogeneous group of disorders characterized by congenital joint contractures often requiring multiple surgeries during childhood to address skeletal and visceral abnormalities. Previous reports suggest that these children have increased perioperative risk, including hypermetabolic events discrete from malignant hyperthermia, difficult airway management, isolated hyperthermia, and difficult IV line placement. We sought to compare children with arthrogryposis multiplex congenita (AMC) versus the less severe, distal arthrogryposis syndromes (DAS) and to evaluate possible intraoperative hyperthermia of patients with AMC. We hypothesized that children with AMC had a greater incidence of intraoperative hyperthermia and more difficulty with airway management and IV access. METHODS: Children aged 0 to 25 years with arthrogryposis syndromes who underwent anesthesia from 1972 to 2013 were identified. The medical records were reviewed for demographics, arthrogryposis type, and anesthetic complications. AMC subjects were compared with DAS subjects. To evaluate the probability of hyperthermia and hypermetabolic responses of patients with AMC, we performed a post hoc case-control analysis. Patients with AMC were matched in a 1:2 ratio to patients without arthrogryposis to evaluate the primary outcome of maximum intraoperative temperature. RESULTS: Forty-five patients with AMC and 16 patients with DAS underwent 264 and 105 unique anesthetics, respectively. There was no significant difference in intraoperative hyperthermia or hypermetabolic events (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.36-2.47; P = .90). Children with AMC were more likely to have difficult IV access (OR, 7.1; 95% CI, 1.81-27.90; P = .005). Additional evidence suggested that difficult airway management (OR, 4.06; 95% CI, 1.01-16.39; P = .049) and hemodynamic instability (OR, 4.22; 95% CI, 1.03-17.26; P = .045) were more likely in children with AMC. From post hoc case-control analysis, there was no significant difference in the mean maximum intraoperative temperature (estimated difference +0.04°C; 95% CI, -0.14 to +0.22; P = .64) or odds of intraoperative hyperthermia (OR, 1.49; 95% CI, 0.78-2.82; P = .223) for patients with AMC compared with control subjects. CONCLUSIONS: Children with arthrogryposis syndromes present challenges to the anesthesia and surgical teams, including greater neuromuscular disease burden and challenging peripheral IV placement, with additional evidence suggesting difficult airway management and intraoperative hemodynamic instability. Although more definitive studies are warranted, we did not find evidence of increased odds of intraoperative hyperthermia or hypermetabolic responses.

Increasing process complexity in the pediatric intensive care unit (PICU) can lead to information overload resulting in missing pertinent information and potential errors during morning rounds. An efficient model using a novel electronic rounding tool was designed as part of a broader critical care decision support system-checklist for early recognition and treatment of acute illness and injury in pediatrics (CERTAINp). We aimed to evaluate its impact on improving the process of care during rounding. Prospective pre- and post-interventional data included: team performance baseline assessment, patient safety discussion, guideline adherence, rounding time, and a survey of Residents' and Nurses' perception using a Likert scale. Attending physicians were blinded to the components of the assessment. A total of 113 pre-intervention and 114 post-intervention roundings were recorded by direct observation. Pre-intervention (108) and post-intervention staff surveys (80) were obtained. Adherence to standard of care guidelines improved to >97 % in all data points, with maximum increase seen in discussions of ulcer prophylaxis, bowel protocol, DVT prophylaxis, skin care, glucose control and head of bed elevation (2-28 % pre-vs. 100 % for all post-intervention, p < 0.01). Significant improvement was noticed in spontaneous breathing trials, sedation breaks and need for devices (45-57 % pre- vs. 100 % for all post-intervention, p < 0.01). Rounding time (mean ± SD) increased by 2 min/patient (8.0 ± 5.8 min pre-intervention vs. 9.9 ± 5.7 min post-intervention, p = 0.002). Staff reported improved perception of all aspects of rounding. Utilization of the CERTAINp rounding tool led to perfect compliance to the discussion of best practice guidelines; had minimal impact on rounding time and improved PICU staff satisfaction.

BACKGROUND: Malignant hyperthermia (MH) is a rare anesthetic pharmacogenetic disorder that can be difficult to detect in its earliest phases. Prompt treatment is known to improve outcomes. The modern anesthesia information management systems (AIMS) collect enormous amounts of data. However, data lack context and are not able to provide real-time guidance. Utilizing our AIMS, we developed the capacity to incorporate decision support. AIMS: We describe the creation and evaluation of a real-time detection tool for MH. METHODS: Cases of MH from 2003 to 2013 were retrospectively reviewed to confirm the diagnosis of MH and to calculate a MH clinical grading scale score. The index cases were utilized to develop four electronic data Rules, based on endtidal CO2 (ETCO2 ) and temperature criteria. The Rules were then applied retrospectively to the index cases and to a full cohort of general operating room (OR) patients from January 2012 to June 2012. If criteria for possible MH was met, the detection tool generated an alert on the monitor at the patient's bedside. RESULTS: We identified seven patients with confirmed MH with MH Scores ranging from 28 to 70. Using four data Rules, all of our seven index cases were captured and generated an appropriate alert. Median time from MH computer alert time to dantrolene administration time among our index cases was 23 min (IQR 17-77). There were 938 false-positive alerts for possible MH (1.8%) when the Rules were applied to a general OR cohort of 51 579 total cases from January 2012 to June 2012. CONCLUSIONS: We demonstrated a real-time MH detection tool based on established physiologic criteria that is sensitive enough to capture cases suspicious for MH, while limiting false positives to prevent alarm fatigue. This has the potential to notify the provider of possible MH such that treatment may be rapidly initiated.

The congenital heart surgeon frequently encounters patients with various genetic disorders requiring surgical intervention. Although the specifics of the genetics for these patients and their families lie in the purview of specialists in genetics, the surgeon is well-served to be familiar with aspects of specific syndromes that impact surgical management and perioperative care. This aids in counseling families in expectations for the hospital course and recovery as well as can impact intraoperative and surgical management. This review article summarizes key characteristics for the congenital heart surgeon to be familiar with for common genetic disorders as they help coordinate care.

BACKGROUND: Sleep-disordered breathing, a common condition in obese children, is a frequent indication for tonsillectomy. OBJECTIVE: The purpose of this study was to examine the association between obesity and perioperative complications in children undergoing tonsillectomy. METHODS/MATERIALS: A sample of 100 severely obese children (body mass index for age [BMIA], ≥ 98 th percentile) between ages 2 and 18 years who underwent tonsillectomy at Mayo Clinic Rochester was randomly selected. Each severely obese child was age (± 2 years) and sex matched to two normal weight children (BMIA between 25th and 75th percentiles) undergoing tonsillectomy during the study period, and their medical records were reviewed. RESULTS: Severely obese children had a significantly higher incidence of comorbid conditions including respiratory disorders and severe systemic disorders or syndromes. Severely obese children had a higher frequency of perioperative airway complications (15.0% vs 2.0%). From posthoc analyses, severe obesity remained a significant risk factor for perioperative adverse events after adjusting for the presence of severe systemic disorders or syndromes (OR 8.8; 95% CI 2.8-27.5, P < 0.001) and also after adjusting for preoperative respiratory disorders (OR 7.7; 95% CI 2.5-24.3, P < 0.001). When children with planned admissions were excluded from the analysis, severe obesity was associated with an increased rate of unplanned hospital admission (OR 3.80, 95% CI 1.8-7.9, P < 0.001). CONCLUSIONS: Severe obesity in children undergoing tonsillectomy is independently associated with an increased risk of perioperative complications. It appears that both severe obesity and systemic comorbid condition contribute to higher proportions of inpatient tonsillectomies performed in our institution.

BACKGROUND: Utah state trauma audit filters assess expeditious care at referring emergency departments for severely injured patients to avoid delays in transfer. We evaluated two state performance measures related to pediatric trauma care before arrival at the Level I trauma center. METHODS: Analysis of the Primary Children's Medical Center (PCMC) trauma database for children with Injury Severity Scores (ISS)>15 from 2006 to 2009 was performed. Patient care was evaluated for referring hospital emergency department triage time of <2 hours and total transfer time of ≤6 hours for rural and ≤4 hours for urban place of injury. RESULTS: Four hundred twelve patients with ISS>15 were admitted via interhospital transfer from within Utah. Approximately 50% of patients were triaged<2 hours, which increased to almost two thirds when restricted to those initially evaluated within 100 miles (helicopter range) of PCMC. Factors associated with delayed triaged included lower ISS, less severe head injury, greater distance from the trauma center, and primary chest/abdominal injuries. Death and poor outcome did not differ significantly by triage in <2 hours or ≥2 hours. Adherence with the total transfer time goal was 94% for rural and 76% for urban place of injury. CONCLUSIONS: There was substantial nonadherence with trauma performance measures for triage in <2 hours among pediatric trauma patients with ISS >15. Because of low rates of poor outcome, we are unable to determine whether adherence with state triage goals lessens morbidity or mortality.

Upper respiratory tract infection (URI) symptoms are known to increase perioperative respiratory adverse events (PRAEs) in children undergoing general anaesthesia. General anaesthesia per se also induces atelectasis, which may worsen with URIs and yield detrimental outcomes. However, the influence of URI symptoms on anaesthesia-induced atelectasis in children has not been investigated. This study aimed to demonstrate whether current URI symptoms induce aggravation of perioperative atelectasis in children. Overall, 270 children aged 6 months to 6 years undergoing surgery were prospectively recruited. URI severity was scored using a questionnaire and the degree of atelectasis was defined by sonographic findings showing juxtapleural consolidation and B-lines. The correlation between severity of URI and degree of atelectasis was analysed by multiple linear regression. Overall, 256 children were finally analysed. Most children had only one or two mild symptoms of URI, which were not associated with the atelectasis score across the entire cohort. However, PRAE occurrences showed significant correspondence with the URI severity (odds ratio 1.36, 95% confidence interval 1.10-1.67, p = 0.004). In conclusion, mild URI symptoms did not exacerbate anaesthesia-induced atelectasis, though the presence and severity of URI were correlated with PRAEs in children.Trial registration: Clinicaltrials.gov (NCT03355547).

Fontan circulation leads to chronic elevation of central venous pressure. We sought to identify the incidence, risk factors, and survival among patients who developed acute kidney injury (AKI) after the Fontan operation. We retrospectively reviewed 1,166 patients who had Fontan operation/revision at Mayo Clinic Rochester from 1973 to 2017 and identified patients who had AKI (defined by AKI Network criteria) within 7 days of surgery. A total of 132 patients (11%) developed AKI after the Fontan operation with no significant era effect. Of those who developed AKI, severe (grade 3) kidney injury was present in 101 patients (76.5%). Multivariable risk factors for AKI were asplenia (odds ratio [OR] 4.2, p <0.0001), elevated preoperative pulmonary artery pressure (per 1 mm Hg increase, OR 1.04, p = 0.0002), intraoperative arrhythmias (OR 1.9, p = 0.02), and elevated post-bypass Fontan pressure (per 1 mm Hg increase, OR 1.12, p = 0.0007). Renal replacement therapy (RRT) was used in 72 patients (54%), predominantly through peritoneal dialysis (n = 56, 78%). Multivariable risk factors for RRT were age ≤3 years (OR 9.7, p = 0.0004), female gender (OR 2.6, p = 0.02), and aortic cross-clamp time >60 minutes (OR 3.1, p = 0.01). Patients with AKI had more postoperative complications, including bleeding, stroke, pericardial tamponade, low cardiac output state and cardiac arrest, than those without AKI. This resulted in longer intensive care unit stay (39 vs 17 days, p = 0.0001). In-hospital mortality was exceedingly higher among patients with AKI versus no AKI (58%, 76 of 132 vs 10%, 99 of 1,034, p <0.0001); however, there was no significant difference based on the need for RRT. Recovery from AKI was observed in 56 patients (42%). Over 20-year follow-up, patients with AKI had a distinctly higher all-cause-mortality (82%) than those without AKI (35%). It is prudent to identity patients at a higher risk of developing postoperative AKI after Fontan operation to ensure renal protective strategies in the perioperative period. Postoperative AKI leads to substantial short and long-term morbidity and mortality, but the need for RRT does not affect the outcomes.

BACKGROUND: Anesthetics administered to immature brains may cause histopathological changes and long-term behavioral abnormalities. The association between perinatal exposure to anesthetics during Cesarean delivery (CD) and development of learning disabilities (LD) was determined in a population-based birth cohort. METHODS: The educational and medical records of all children born to mothers residing in five townships of Olmsted County, Minnesota from 1976-1982 and remaining in the community at age 5 were reviewed to identify those with LDs. Cox proportional hazards regression was used to compare rates of LD between children delivered vaginally and via CD (with general or regional anesthesia). RESULTS: Of the 5,320 children in this cohort, 497 were delivered via CD (under general anesthesia n = 193, and regional anesthesia n = 304). The incidence of LD depended on mode of delivery (P = 0.050, adjusted for sex, birth weight, gestational age, exposure to anesthesia before age 4 yr, and maternal education). LD risk was similar in children delivered by vagina or CD with general anesthesia, but was reduced in children receiving CD with regional anesthesia (hazard ratio = 0.64, 95% confidence interval 0.44 to 0.92; P = 0.017 for comparison of CD under regional anesthesia compared to vaginal delivery). CONCLUSION: Children exposed to general or regional anesthesia during CD are not more likely to develop LD compared to children delivered vaginally, suggesting that brief perinatal exposure to anesthetic drugs does not adversely affect long-term neurodevelopmental outcomes. The risk of LD may be lower in children delivered by CD whose mothers received regional anesthesia.

BACKGROUND: Anesthetic drugs administered to immature animals may cause neurohistopathologic changes and alterations in behavior. The authors studied association between anesthetic exposure before age 4 yr and the development of reading, written language, and math learning disabilities (LD). METHODS: This was a population-based, retrospective birth cohort study. The educational and medical records of all children born to mothers residing in five townships of Olmsted County, Minnesota, from 1976 to 1982 and who remained in the community at 5 yr of age were reviewed to identify children with LD. Cox proportional hazards regression was used to calculate hazard ratios for anesthetic exposure as a predictor of LD, adjusting for gestational age at birth, sex, and birth weight. RESULTS: Of the 5,357 children in this cohort, 593 received general anesthesia before age 4 yr. Compared with those not receiving anesthesia (n = 4,764), a single exposure to anesthesia (n = 449) was not associated with an increased risk of LD (hazard ratio = 1.0; 95% confidence interval, 0.79-1.27). However, children receiving two anesthetics (n = 100) or three or more anesthetics (n = 44) were at increased risk for LD (hazard ratio = 1.59; 95% confidence interval, 1.06-2.37, and hazard ratio = 2.60; 95% confidence interval, 1.60-4.24, respectively). The risk for LD increased with longer cumulative duration of anesthesia exposure (expressed as a continuous variable) (P = 0.016). CONCLUSION: Exposure to anesthesia was a significant risk factor for the later development of LD in children receiving multiple, but not single anesthetics. These data cannot reveal whether anesthesia itself may contribute to LD or whether the need for anesthesia is a marker for other unidentified factors that contribute to LD.

The forearm vasodilator response to mental stress is multifactorial and widely variable among individuals. We evaluated the association between the heart rate and forearm vascular conductance (FVC) responses to a color word test in 101 healthy adults. We found a striking correlation between heart rate and FVC (r = 0.66, P < 0.001), which remained significant when controlling for subject characteristics, blood pressure, and catecholamines. This suggests that the mechanical stimulation is one of the key factors that contribute to the increase in FVC during mental stress.
