A retrospective cohort study of the association of anesthesia and hernia repair surgery with behavioral and developmental disorders in young children

Recent animal studies have shown that commonly used anesthetic agents may have serious neurotoxic effects on the developing brain. The purpose of this study was to assess the association between surgery for hernia repair and the risk of behavioral and developmental disorders in young children. We performed a retrospective cohort analysis of children who were enrollees of the New York State Medicaid program. Our analysis involved following a birth cohort of 383 children who underwent inguinal hernia repair during the first 3 years of life, and a sample of 5050 children frequency-matched on age with no history of hernia-repair before age 3. After controlling for age, sex, and complicating birth-related conditions such as low birth weight, children who underwent hernia repair under 3 years of age were more than twice as likely as children in the comparison group to be subsequently diagnosed with a developmental or behavioral disorder (adjusted hazard ratio 2.3, 95% confidence interval 1.3, 4.1). Our findings add to recent evidence of the potential association of surgery and its concurrent exposure to anesthetic agents with neurotoxicity and underscore the need for more rigorous clinical research on the long-term effects of surgery and anesthesia in children.

Sleepless in America: Inadequate Sleep and Relationships to Health and Well-being of Our Nation's Children

OBJECTIVE. Our goal was to identify characteristics associated with inadequate sleep for a national random sample of elementary school–aged children (6–11 years) and adolescents (12–17 years). METHODS. Data from 68418 participants in the 2003 National Survey of Childrens Health were analyzed by using weighted bivariate and multivariate regression models. The dependent variable was report of not getting enough sleep for a child of his or her age ≥1 night of the past week. Independent variables included demographic characteristics, child health, school and other activities, and family life. RESULTS. Parents of elementary school–aged children with inadequate sleep were more likely to report that their child was having problems at school or had a father with fair or poor health. Parents of adolescents with inadequate sleep were more likely to report that their child had an atopic condition, frequent or severe headaches, a parent with less-than-excellent emotional health, or experienced frequent parental anger. Inadequate sleep in both age groups was associated with parental report that their child usually or always displayed depressive symptomatology, family disagreements involved heated arguing, or parental concern that the child was not always safe at home, at school, or in their neighborhood. CONCLUSIONS. Approximately 15 million American children are affected by inadequate sleep. Primary care providers should routinely identify and address inadequate sleep and its associated health, school, and family factors.

Association Between a Single General Anesthesia Exposure Before Age 36 Months and Neurocognitive Outcomes in Later Childhood.

IMPORTANCE Exposure of young animals to commonly used anesthetics causes neurotoxicity including impaired neurocognitive function and abnormal behavior. The potential neurocognitive and behavioral effects of anesthesia exposure in young children are thus important to understand. OBJECTIVE To examine if a single anesthesia exposure in otherwise healthy young children was associated with impaired neurocognitive development and abnormal behavior in later childhood. DESIGN, SETTING, AND PARTICIPANTS Sibling-matched cohort study conducted between May 2009 and April 2015 at 4 university-based US pediatric tertiary care hospitals. The study cohort included sibling pairs within 36 months in age and currently 8 to 15 years old. The exposed siblings were healthy at surgery/anesthesia. Neurocognitive and behavior outcomes were prospectively assessed with retrospectively documented anesthesia exposure data. EXPOSURES A single exposure to general anesthesia during inguinal hernia surgery in the exposed sibling and no anesthesia exposure in the unexposed sibling, before age 36 months. MAIN OUTCOMES AND MEASURES The primary outcome was global cognitive function (IQ). Secondary outcomes included domain-specific neurocognitive functions and behavior. A detailed neuropsychological battery assessed IQ and domain-specific neurocognitive functions. Parents completed validated, standardized reports of behavior. RESULTS Among the 105 sibling pairs, the exposed siblings (mean age, 17.3 months at surgery/anesthesia; 9.5% female) and the unexposed siblings (44% female) had IQ testing at mean ages of 10.6 and 10.9 years, respectively. All exposed children received inhaled anesthetic agents, and anesthesia duration ranged from 20 to 240 minutes, with a median duration of 80 minutes. Mean IQ scores between exposed siblings (scores: full scale = 111; performance = 108; verbal = 111) and unexposed siblings (scores: full scale = 111; performance = 107; verbal = 111) were not statistically significantly different. Differences in mean IQ scores between sibling pairs were: full scale = -0.2 (95% CI, -2.6 to 2.9); performance = 0.5 (95% CI, -2.7 to 3.7); and verbal = -0.5 (95% CI, -3.2 to 2.2). No statistically significant differences in mean scores were found between sibling pairs in memory/learning, motor/processing speed, visuospatial function, attention, executive function, language, or behavior. CONCLUSIONS AND RELEVANCE Among healthy children with a single anesthesia exposure before age 36 months, compared with healthy siblings with no anesthesia exposure, there were no statistically significant differences in IQ scores in later childhood. Further study of repeated exposure, prolonged exposure, and vulnerable subgroups is needed.

Feasibility and Pilot Study of the Pediatric Anesthesia NeuroDevelopment Assessment (PANDA) Project

Background: Animal studies have documented that exposure of the developing brain to commonly used anesthetic agents induces neurotoxicity and late abnormal neurobehavioral functions as adults. Results from clinical studies have all been analyzed using existing data sets, and these studies produced inconsistent results. To provide more definitive evidence to address the clinical relevance of anesthetic neurotoxicity in children, an interdisciplinary team of investigators designed and developed the Pediatric Anesthesia NeuroDevelopment Assessment (PANDA) project. We present pilot study results in 28 sibling pairs recruited and tested at the Columbia University Medical Center (CUMC) and Children’s Hospital of Boston (CHB) for the PANDA project. Methods: The PANDA project uses an ambidirectional cohort design. We performed prospective neuropsychological assessment in 28 exposed-unexposed sibling pairs from 6 to 11 years of age. The exposed siblings were ASA 1 or 2 and had received a single episode of anesthesia for inguinal hernia repair before the age of 36 months and the unexposed siblings had no anesthesia before the age of 36 months. All the sibling pairs were English speaking and were 36 weeks of gestational age or older. Each sibling pair underwent a direct testing using the Wechsler Abbreviated Scale of Intelligence (WASI) and the NEuroPSYchological Assessment, second edition (NEPSY II), and the parents completed questionnaires related to behavior using CBCL and Conners rating. Data are presented as means±SD. We conducted descriptive analyses of the demographic data. We compared both the exposed and the unexposed sibling groups on WASI and NEPSY II, and total and T scores from CBCL and Conners rating were analyzed as continuous data using the paired t test between the two groups. A P<0.05 was considered significant. Results: After the Institutional Review Board approval for the study at both CUMC and CHB, the full PANDA study protocol was implemented to perform a pilot feasibility study. Our success rate was 96.7% in obtaining detailed medical and anesthesia records in our historical cohort. The scores for verbal IQ (exposed=106.1±16.3, unexposed=109.2±17.9), performance IQ (exposed=109.1±16.0, unexposed=113.9±15.9), and full IQ (exposed=108.2±14.0, unexposed=112.8±16.8) were comparable between the siblings. There were no differences between the two groups in T scores for any of the NEPSY II subdomains, CBCL, or Conners rating. An abstraction protocol with web-based electronic data capture forms also was developed in conjunction with the International Center for Health Outcomes and Innovation Research (InCHOIR). Conclusions: The pilot study provided useful information for feasibility to recruit the sample size and to obtain relevant clinical data. For the final study protocol, both the neuropsychological battery and the age range for testing were revised. Our results confirmed the feasibility of our study approach and yielded pilot data from neuropsychological testing.

Anesthesia and neurodevelopment in children: time for an answer?

Editor’s Note: This is the first in a three-part series of Editorial Views regarding design of clinical trials to address the effect of anesthesia on the developing brain. Animal studies have suggested that anesthetic exposure could affect neurocognitive development, and there is an urgent need for clinical trials to determine whether this effect occurs in humans. This series presents the opinions of three world thought leaders in the possible designs of such clinical trials.

Attachment organization in a sample of incarcerated mothers: Distribution of classifications and associations with substance abuse history, depressive symptoms, perceptions of parenting competency and social support

We report attachment classifications in a sample of pregnant women incarcerated in a state prison with a nursery program. Analyses were based on 69 women serving sentences for felony crimes who were followed from the birth of their child to completion of the prison nursery co-residence. They completed the Adult Attachment Interview shortly after entering the program and scales measuring depression, perceived parenting competency, and social support at study entry (Time 1) and program completion (Time 2). Incarcerated mothers had higher rates of insecure attachment than previous low-risk community samples. Compared with dismissing and secure mothers, preoccupied mothers reported higher levels of depressive symptoms, lower parenting competency, and lower satisfaction with social support at the conclusion of the nursery program. Higher scores on unresolved loss and derogation were associated with a history of substance abuse; higher scores on unresolved trauma were associated with depressive symptoms at program completion.

Converging Streams of Opportunity for Prison Nursery Programs in the United States

Prison nursery programs allow departments of correction to positively intervene in the lives of both incarcerated mothers and their infant children. The number of prison nurseries in the United States has risen dramatically in the past decade, yet there remains a significant gap between predominant correctional policy in this area and what is known about parenting and infant development. Using Kingdons streams metaphor, this article examines the recent convergence of problem, policy, and political events related to incarcerated women with infant children and argues that this has created a window of opportunity for development of prison nursery programs. Adays policy analysis criteria are also used to analyze available evidence regarding the effectiveness, efficiency, and equity of prison nursery programs as policy alternatives for incarcerated women with infant children.Prison nursery programs allow departments of correction to positively intervene in the lives of both incarcerated mothers and their infant children.

Delayed and Forgone Care for Children with Special Health Care Needs in New York State

Objective: To identify characteristics associated with delayed/forgone care for children with special health care needs (CSHCN) in New York State (NYS) as reported by their parents. Methods: Data come from NYS participants in the 2000–2002 National Survey of Children with Special Health Care Needs. Data were analyzed using weighted bivariate and multivariate regression models. The dependent variable was report of delayed/forgone routine health care. Independent variables included illness characteristics, potential and actual access to care, and provider care characteristics. Results: In NYS, 8.4% reported delayed/forgone health care for their child. Parents of children with delayed/forgone care were more likely to report that their child was uninsured (adjusted odds ratio [aOR] 3.8, 95% confidence interval [CI] 1.3–11.8), had experienced interrupted health insurance (aOR 3.9, 95% CI 1.5–9.7), or their child’s insurance was not adequate for CSHCN (aOR 3.6, 95% CI 1.4–9.1). Further, these parents were more likely to report that providers never spend adequate time (aOR 6.3, 95% CI 1.2–34.4), provide sufficient information (aOR 8.0, 95% CI 2.5–25.0), act as partners in care (aOR 6.7, 95% CI 2.3–19.7), or display cultural sensitivity (aOR 5.4, 95% CI 1.2–24.3). Conclusions: An estimated 40,771 NYS CSHCN experience delayed/forgone routine health care. Their families report two noteworthy barriers: inadequate or discontinuous insurance coverage and poor communication with health-care providers. Access to care for CSHCN can be improved by increasing consistent comprehensive insurance coverage and increasing sensitivity in relationships between health care providers and families of CSHCN.

Comparison of two measures of parent-child interaction.

BackgroundThe numerous parent-child interaction measures available include few that are appropriate to brief clinical encounters or to research settings where time, cost, space, and subject burden are critical factors. ObjectivesThis study compares the newer Mother-Infant Communication Screening (MICS) with the established Nursing Child Assessment Satellite Training (NCAST) Teaching Scale (NCAT). MethodsTheoretical foundations, development, administration, support, and published psychometrics for the two scales are contrasted. Videotapes of 171 caregiver-child interactions in an urban, Hispanic, high-risk sample (children aged 5 months to 36 months) were scored by two trained coders who had established inter-rater reliabilities of .90 (NCAT) and .85 (MICS). ResultsValidity correlation coefficients were r = .504, p < .001 for total scores and r = .492, p < .001 for the two most comparable subscales. Distress was defined more narrowly by the MICS. Internal consistencies were .89 to .94 (MICS total scores) (depending on choice of subscales used) and .79 (NCAT). ConclusionsThe NCAT has established strengths for use in clinical practice and research and provides dyadic and separate mother and child scores. The MICS is more feasible for brief clinical screening and performed in this study with promising correlate validity and internal consistency across ages (infancy through 3 years). Interpretation would be strengthened if more clinical studies verifying scores with risk categories were performed and if normative data were established.

Elective procedures and anesthesia in children: pediatric surgeons enter the dialogue on neurotoxicity questions, surgical options, and parental concerns.

The Pediatric Anesthesia NeuroDevelopment Assessment research group at Columbia University Medical Center Department of Anesthesiology has conducted biannual national Symposia since 2008 to evaluate study data and invigorate continued thinking about unresolved issues of pediatric anesthesia neurotoxicities. The third Symposium extended the dialogue between pediatric anesthesiologists and surgeons in panel presentations and discussions by four surgical specialists. This paper reports the prevailing opinions expressed by a pediatric general surgeon, urologist, plastic surgeon and ophthalmologist and explores factors related to delayed operative intervention, need for multiple procedures, and parental concerns.
