"This study suggests that exposure to epidural analgesia for vaginal delivery may be associated with increased risk of autism in children; further research is warranted to confirm the study findings and understand the potential mechanisms."

Quwstion: are pregnant women who choose epidural different than those who don't? Are there clinical situations where pregnant women are strongly advised from a medical perspective to get an epidural? There are your co-founders right there. Do obstetricians treat the delivery differently with epiduralized patients? Took me 1 minute to tear down their paper.

I dont see how its not out of the realm of possibility. We do eras protocols with lifo infusions where people with giant incisions require minimal narcotic. Clearly they have an effect on the brain and body. Obviously the blood absorbancy of local anesthetic from the epidural space is very low, and maternal transfer is very low. However, in a developing brain, even a small amount of local may cause changes or have effects.

Also, does the use of epidurals allow the ob doctors to blast pitching at rates much higher than people can tolerate without epidurals? Could that also be a factor?

Extraordinary claims require extraordinary evidence.

I want to see what the evidence is on the 1. Duration of epidural and total dose of local anwsthetjc administered, 2. If such association also seen with spinal anesthesia. 3. Does choice of local anesthetic matter?? One that has less placental transfer and accumulation would intuitively have less effect.. Seems it they are claiming local anesthesia causes such fetal effects, then they actually need evidence not an association

Fine. Let the same people who follow Jenny Mc Carthy's vaccine advice refuse epidurals and save future anesthesiologists the aggravation.

Watch for the "have you or a loved one developed autism and had an epidural involved in your delivery? If so call 1-800-SCUMBAGS....." commercials.

M0r0nic. Doubt this will steer most women away from getting an epidural but will require me to 1) spend more time answering dumb questions about epidurals and autism and 2) will have to wait to do epidurals on women who are almost completely dilated and in unbearable pain because they thought they could do it “natural.”

I have made widely known on L&D that all my epidurals between 0:00 and 7:30 result in 100% autism in the child.

Retrospective study of little value except causing one more question before the epidural. One in 4 pregnant women are meth positive in Central Valley, California. No way or how she will deliver without a working epidural. Corelation with autism does not mean causation

Weak data and weak study (retrospective) coming out of Kaiser Permanante Anesthesia folks. No purpose to this study except to cause hysteria and waste funding to try and substantiate this nonsense.

It seems like a decently designed retrospective study. Nothing we do is benign and this correlation seems not un-plausible. I'm skeptical of the outcome but would like to see some specific breakdowns of their study rather than gut reaction opposition.

But again, I find the correlation suspect.

Kaiser permanente has a great reputation among lay people and is a wall street darling that has succeeded in lowering health care costs. However in this study, what happens To autism rate, if the epidural is not given? It will lead to less perineal relaxation and more instruments delivery and more csect rate leading to a Higher incidence and severity of autism because the baby brain is then subjected to general anesthesia For instrument delivery. We all know the advantage of regional vs general anesthesia in Ob population.
The midwives will be very happy withthese kinds of studies and the Obgyn will have to rescue more and take on more liability.

Exactly. The assumption is the patient population that choose epidural vs no epidural is the same. That is clearly not true.

I didn't see them account for paternal age which is a large risk factor.


Published by JAMA 14 years ago.

Plus they didn't account for illicit substance use. Meth use is exploding and is implicated in increased autism risk. Plenty of these Kaiser locations have patients rolling in with meth use (Baldwin Park for example).

I'm not saying there couldn't be an association but if you miss big variables, garbage in ==>garbage out.

I may have missed this but did they mention the average labor time for the non epidural group? From what I read it was the patients with prolonged labor (> 8 hours) in the epidural group that had the highest rates of autism. Did the non epidural patients have super quick labor times (hence not receiving an epidural) and if so was that a confounding variable?

It seems pregnancy itself is strongly associated with autism. It is clear that since 100% of autistic kids had a mother that was pregnant, that the only way to avoid autism is to avoid pregnancy. By the time they ask for the epidural, it is too late.

Quite frankly, I’m amazed this got published in JAMA. But there it is, you can get a statistician to crunch some numbers and publish anything.

I think there should be some requirement to have a truely logical reason to do a study like this, otherwise the results can only be misconstrued by the public:

Key Points

Question Is epidural labor analgesia (ELA) associated with increased offspring risk of autism spectrum disorder (ASD)?

Findings In this cohort study of 123 175 offspring born in Manitoba, Canada, from 2005 to 2016, after accounting for maternal sociodemographic, preexisting, pregnancy-related, and birth-specific factors, no association was found between ELA exposure and offspring risk of ASD.

Meaning Results of this study suggest that ELA is not associated with an increased risk of ASD in offspring.

Abstract

Importance Epidural labor analgesia (ELA) has been associated with an increased offspring risk of autism spectrum disorder (ASD). Whether this finding may be explained by residual confounding remains unclear.

Objective To assess the association between ELA and offspring risk of ASD.

Design, Setting, and Participants Longitudinal cohort study of vaginal deliveries of singleton live infants born from 2005 to 2016 from a population-based data set linking information from health care databases in Manitoba, Canada; offspring were followed from birth until 2019 or censored by death or emigration. Data were analyzed from October 19, 2020, to January 22, 2021.

Exposures Epidural labor analgesia.

Main Outcomes and Measures At least 1 inpatient or outpatient diagnosis of ASD in offspring aged at least 18 months. For the full population and a sibling cohort, inverse probability of treatment-weighted Cox proportional hazards regression analyses were used to control for potential confounders.

Results

Of the 123 175 offspring included in this study (62 647 boys [50.9%]; mean [SD] age of mothers, 28.2 [5.8] years), 47 011 (38.2%) were exposed to ELA; 2.1% (985 of 47 011) of exposed vs 1.7% (1272 of 76 164) of unexposed offspring were diagnosed with ASD in the follow-up period (hazard ratio
, 1.25; 95% CI, 1.15-1.36). After adjusting for maternal sociodemographic, prepregnancy, pregnancy, and perinatal covariates, ELA was not associated with an offspring risk of ASD (inverse probability of treatment–weighted HR, 1.08; 95% CI, 0.97-1.20). In the within-siblings design adjusting for baseline covariates, ELA was not associated with ASD (inverse probability of treatment–weighted HR, 0.97; 95% CI, 0.78-1.22). Results from sensitivity analyses restricted to women without missing data who delivered at or after 37 weeks of gestation, firstborn infants only, and offspring with ASD classified with at least 2 diagnostic codes were consistent with findings from the main analyses.

Conclusions and Relevance

In a Canadian population-based birth cohort study, no association between ELA exposure and an increased offspring risk of ASD was found.

I’m far from an autism expert. Would be interested to see if the rate of autism is similar in other developed countries with a strong healthcare system and equal rate of epidural use for labor and delivery.
 
Again association is meaningless. An association could just as easily mean “autistic babies cause more painful labor increasing the incidence of epidural labor analgesia.”

I truly don't understand why people don't think it's a possibility and should be studied more instead of just brushed aside. Who knows what ill effects local anesthetics can do to a fetal brain.

Does this even matter? A significant % of my patients think they are at high risk of paralysis due to an epidural (before I talk to them) and they are begging for it. I wonder how many would be swayed by a mention of autism 🤔

Was waiting for someone to publish a follow up to the crappy Kaiser study. Hopefully this will be it and we don’t get a bunch more useless retrospective studies to show there’s no link with autism, it’s just an absolute waste of time and resources.

post hoc ergo propter hoc fallacies surrounding epidurals have been around since the late 20th century. the list just keeps getting longer and longer. could save a lot of time by just going with the standby 'anesthesia's fault'. Sad part is, physicians are fighting each other over this stuff...

because they want to land in JAMA, and not just anesthesiology. autism is always a hot topic for dumb reasons

they've probably already moved on to the next study. 'propofol may be associated with autism'

Braun should sue JAMA and the authors for harming their business. Heck we anesthesiologists should get together and file a class action.

Exactly. It’s also been shown that MediCaid epidurals have a higher incidence than privately insured ones.

Yeah, forget the 9 months of pregnancy and all that entails, or the cognitive development/nutrition/environment from birth to diagnosable age. It’s about that last 2-8 hours of pregnancy where a local anesthetic is infusing and is minimally absorbed.
