Epidemiology of general anesthesia prior to age 3 in a population-based birth cohort.

ABSTRACT: 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.

Project description:Exposure to general anesthesia has been reported to induce neurotoxicity, impair learning, memory, attention, motor functions, as well as affect behavior in adult rodents and nonhuman primates. Though many have speculated similar effects in humans, previous literature has shown conflicting findings. To investigate the differences in risk of developmental delay among young children exposed to general anesthesia compared to matched unexposed individuals, a population-based cohort study was conducted with a longitudinal dataset spanning 2000 to 2013 from the Taiwan National Health Insurance Research Database (NHIRD). Procedure codes were used to identify children who received anesthesia. For each exposed child, two unexposed children matched by gender and age were enrolled into the comparison cohort. Neurocognitive outcome was measured by the presence of ICD-9-CM codes related to developmental delay (DD). Cox regression models were used to obtain hazard ratios of developing DD after varying levels of anesthesia exposure. After excluding 4,802 individuals who met the exclusion criteria, a total of 11,457 children who received general anesthesia before two years of age was compared to 22,914 children (matched by gender and age) unexposed to anesthesia. Increased risk of DD was observed in the exposure group with a hazard ratio (HR) of 1.320 (95% CI 1.143-1.522, P < 0.001). Subgroup analysis demonstrated further elevated risks of DD with multiple anesthesia exposures (1 anesthesia event: HR 1.145, 95% CI 1.010-1.246, P = 0.04; 2 anesthesia events: HR 1.476, 95% CI 1.155-1.887, P = 0.005; ≥3 anesthesia events: HR 2.222, 95% CI 1.810-2.621, P < 0.001) and longer total anesthesia durations (Total anesthesia <2 hours: HR 1.124, 95% CI 1.003-1.499, P = 0.047; Total anesthesia 2-4 hours: HR 1.450, 95% CI 1.157-1.800, P = 0.004; Total anesthesia > 4 hours: HR 1.598, 95% CI 1.343-1.982, P < 0.001) compared with children unexposed to anesthesia. These results suggest that children exposed to general anesthesia before two years of age have an increased risk of DD. This risk is further elevated with increased frequency of anesthesia, and longer total anesthesia duration. The findings of this study should prompt clinical practitioners to proceed with caution when assessing young patients and planning managements involving procedures requiring general anesthesia.

Project description:Although cesarean section (CS) has become a common method of child delivery in recent decades, the choice between general anesthesia (GA) and neuraxial anesthesia (NA) for CS must be carefully considered. Depending on the type of anesthesia used in CS, a major outcome observed is the occurrence of postpartum depression (PPD). This study investigated the association between PPD risk and the anesthesia method used in CS by using data from three linked nationwide databases in Taiwan, namely, the National Health Insurance Research Database, the National Birth Reporting Database, and the National Death Index Database. After propensity score matching by baseline depressive disorders, maternal demographics, status at delivery, infant’s health, maternal diseases during pregnancy, and age of partner, we included women who had natural births (n = 15,706), cesarean sections with GA (n = 15,706), and cesarean sections with NA (n = 15,706). A conditional logistic regression was used to estimate the odds ratios and 95% confidence intervals (CIs) of PPDs, including depression, sleep disorder, and medication with hypnotics or antidepressants, under anesthesia during CS. The prevalence rates of combined PPDs were 26.66%, 43.87%, and 36.30% in natural births, CS with GA, and CS with NA, respectively. In particular, the proportions of postpartum use of hypnotic drugs or antidepressants were 21.70%, 39.77%, and 31.84%, which were significantly different. The aORs (95% CIs) were 2.15 (2.05–2.25) for the included depressive disorders, 1.10 (1.00–1.21) for depression, 1.03 (0.96–1.11) for sleep disorder, and 2.38 (2.27–2.50) for medication with hypnotics or antidepressants in CS with GA compared with natural births. Women who underwent CS with GA had a significantly higher risk of depressive disorders and a higher need for antidepressants for sleep problems than those who underwent CS with NA. The risks of PPD were significantly associated with the anesthesia method, especially GA. Our results can assist physicians in carefully considering the appropriate anesthesia method for CS delivery, particularly with regard to postpartum drug abuse and drug safety.
