Adverse Events in Airway Procedures in Kids: Key Risks
Adverse events occurred in 2% of children who underwent procedures for airway management under general anesthesia, with higher rates in neonates and infants. Risk factors included younger age, the presence of anatomic difficulties, and undergoing anesthesia outside operating rooms.
METHODOLOGY:
Researchers conducted a prospective observational study at 10 tertiary care hospitals in Japan from June 2022 to January 2024, focusing on the incidence of adverse events during airway management in children under general anesthesia.
A total of 16,695 children (mean age, 6.3 years; 41.4% girls; 1.8% neonates and 11.7% infants) received advanced airway management at least once under general anesthesia, with or without regional anesthesia, including tracheal intubation or the placement of a supraglottic airway device.
Data on patient comorbidities, types of surgeries, training levels of anesthesia providers, and practices for airway management were collected.
The primary outcome was the occurrence of adverse events related to airway management procedures during general anesthesia; the secondary outcome was desaturation, defined as a drop in oxygen saturation of at least 10%.
Occurrences of any adverse events, including at least one hemodynamic and airway-related complication, and respiratory adverse events were recorded, and risk factors for adverse events and desaturation were identified.
TAKEAWAY:
Any adverse events occurred in 2% of cases of airway management, and desaturation was noted in 2.3% of cases. The incidence of any adverse events was 5.8% in neonates and 3.3% in infants, higher than that in preschool and school-going children and adolescents.
Increasing age was linked to reduced odds of any adverse events (adjusted odds ratio [aOR], 0.92; P < .001). Insertion of a supraglottic airway device and the use of muscle relaxants at first attempt were also linked to reduced odds of any adverse events.
Factors associated with increased odds of any adverse events included undergoing anesthesia in CT, MRI, or radiation therapy rooms (aOR, 5.7; P = .006); having airway sensitivity (aOR, 1.46; P = .010); and having one (aOR, 1.74; P = .042) or at least two (aOR, 2.82; P = .017) anatomic difficulties.
The odds of desaturation decreased with increasing age (aOR, 0.78; P < .001) but were higher when anesthesia was provided in catheter labs and CT, MRI, or radiology therapy rooms than when provided in operating rooms. Airway management by nonspecialist anesthesiologists and trainees also was linked to higher odds of desaturation than when the intervention was performed by pediatric anesthetists.
IN PRACTICE:
'Our study, focusing specifically on airway management, showed that approximately 21% of neonates and 7% of infants experienced desaturation, which was higher than that in other age groups,' the researchers reported. 'Neonates' unique physiological and anatomical characteristics can explain this hypoxic progression tendency…The higher desaturation incidence in neonates in our study highlights the necessity for shorter tracheal intubation time and higher first-attempt success rates in neonates,' they added.
SOURCE:
This study was led by Taiki Kojima, MD, MPH, of the Department of Anesthesiology at Aichi Children's Health and Medical Center in Obu, Japan. It was published online on July 07, 2025, in Anesthesiology.
LIMITATIONS:
The reliance on self-reported data from anesthesiologists may have introduced reporting bias and inaccuracies. Selection bias could have occurred due to missing cases, and unmeasured confounders may have affected the results. The exact incidence of adverse events by device type remained unclear due to multiple attempts with different devices.
DISCLOSURES:
The J-PEDIA study was funded by grants from the Ministry of Education in Japan. This study received Grants-in-Aid for Scientific Research from the Ministry of Education in Japan. No additional conflicts of interest were disclosed by the authors.

How to Care for Cuts, Scrapes, and Stitches in Kids
A Pediatrician's Guide to Wound Care, Healing, and When to See a Doctor It's natural to feel a pit in your stomach when your child gets hurt, whether it's a scraped knee from a playground tumble or a cut that makes your heart race a little. Knowing what to do in the moment can help your child heal faster, stay infection-free, and even reduce the chance of scarring. Types of Wounds in Children First, let's break down what kind of wound you're dealing with. The two most common are abrasions (aka scrapes) and lacerations (aka cuts). Abrasions happen when the skin gets scraped against something rough, think tripping on the sidewalk or sliding on concrete. These usually aren't deep but can cover a large area. Lacerations are deeper cuts that break through more layers of skin. These can come from sharp edges, broken glass, or a fall with impact. Some lacerations can be handled at home, but others need medical closure like stitches, staples, or dermabond (medical glue). Does my child's cut need medical attention? While many minor cuts can be treated at home, some wounds need medical closure. This is especially important to prevent infection, speed healing, and minimize scarring. Here's when to get your child's wound checked out: The wound is deep, with edges that stay apart even when you press them together. It was a deep puncture wound (such as stepping on a nail). Bleeding doesn't stop after five minutes of direct pressure. The wound is over a joint or a high-tension area (elbows, knees, etc.) The cut is on the face, particularly near the lips or eyes. A human or animal bite caused the wound and broke the skin You cannot get the wound clean and still see significant debris inside Wound closure options If your clinician recommends closing the wound, they'll consider the size, depth, location, and how clean it is. The main closure methods are: Dermabond (medical glue): A go-to for clean, small cuts, especially on the face or upper body. It's fast, painless, and less scary for kids. But it can't be used in high-moisture spots, over joints, or near the eyes. Stitches: Best for longer or jagged cuts and areas that move a lot. The area is numbed before stitches go in. Some are dissolvable; others need to be removed later. Staples: Often used for the scalp or thick-skinned areas. Quick and strong—but they'll need to be removed after 7–10 days. How to care for wounds at home Even if the wound doesn't need stitches, how you treat it at home really matters. Here's a simple, clear routine: Step 1: Stop the bleeding. Use clean gauze or a towel and apply pressure until bleeding slows. If it hasn't stopped after 5 minutes, check in with your child's provider. Step 2: Clean it gently. Skip the hydrogen peroxide, it kills healthy cells, not just bacteria. Use mild soap and lukewarm water, then pat dry with a clean towel. Step 3: Follow specific care instructions. For dermabond: keep the area dry for 24 hours, and let the glue fall off on its own. For stitches or staples: keep it clean and dry the first day, then follow your provider's directions. Keep the area covered and avoid soaking. Step 4: Moisturize the wound. This surprises a lot of people, but petroleum jelly like Vaseline or Aquaphor helps keep the wound moist and prevents scabbing. A moist wound heals faster and reduces scarring. Step 5: Go easy on antibiotic ointments. Neosporin is everywhere, but it can cause allergic reactions due to neomycin. Ask your pediatrician if Bacitracin is a safer option for your child. Step 6: Keep it covered. A clean, non-stick bandage protects the wound from germs. Just make sure it's not too tight, you want good circulation. Bonus: fun, colorful bandages can make it less scary for your child. Reducing the risk of scarring One common concern for parents is how to prevent scarring after their child's injury. While it's nearly impossible to avoid scarring entirely, there are a few steps you can to take to reduce its appearance. Keep the wound moist. Petroleum jelly is your best friend here. Silicone sheets (like ScarAway) can help reduce visible scars once the skin is closed. Check the label for age guidelines and usage instructions. Sun protection is key. UV rays can darken scars, especially on new skin. Keep it covered or use a kid-safe sunscreen. Remind your child not to pick. Scabs can be tempting little targets. Bandages and rewards help keep little hands away. Signs of infection: when to call your child's clinician Most wounds start to look better every day. If things are going the other direction, such as becoming more red, swollen, or painful, it's time to call in backup. Watch for: Redness, swelling, or increasing pain, especially after day 2 Warm skin around the wound Pus or unusual drainage Fever or feeling unwell Red streaks moving away from the cut The bottom line Accidents and injuries are a part of childhood, but with the right care, your child's wound can heal properly with minimal scarring. Knowing when to seek medical attention, how to care for wounds, and the most common mistakes to avoid can help you feel prepared to care for your child's wound. Check out the PedDocTalk YouTube video on wound care for more tips on wound healing, including what to expect from a visit to the clinician for a wound and how to reduce scarring. Remember, your child's clinician is always a resource if you have any concerns or questions about wound care.

No. Eggs Won't Impact Your Cholesterol and 17 Other Health Myths You Can Stop Believing
Cracking your knuckles will cause arthritis. Eggs impact your cholesterol levels. Coffee stunts your growth. For decades, health myths like these have influenced consumer decisions, originating from obscure studies or the opinion of a then-influential doctor. Science has debunked much of this conventional wisdom that percolates as fact. Here are 18 of the most common health myths that everyone needs to stop believing right now. Myth: Exercising at night ruins your sleep Feel free to work out at night if that's your jam. Getty Images The truth: Not for everyone. The advice of late-1900s exercise professionals would have you believe that exercising too late in the evening keeps you up at night. It's just not true for everyone: Researchers have found that certain nighttime exercises like yoga or weightlifting may have no impact whatsoever on your sleep quality, and for some people, exercising before bed can even result in better ZZZs. Read more: How to Get Better Sleep Myth: Eating eggs causes high cholesterol Go ahead and eat your omelet. Getty Images The truth: Eggs have almost no effect on your blood cholesterol. You, among millions of others influenced by the 1968 recommendation that adults should eat no more than three whole eggs per week, may have needlessly avoided eggs for the last 50 years. Scientists have since debunked the idea that eggs increase your blood cholesterol and heighten your risk for heart disease, and recent research even suggests that eating eggs can improve your heart health. Myth: You must drink 64 ounces of water each day PhotoAlto/The truth: Everyone has different hydration needs. Everyone knows the eight-by-eight rule: Drink eight 8-ounce glasses of water each day. This water intake recommendation stems from a very outdated -- in this case, centuries-old -- ideal. While based on accurate observations (water keeps you healthy), the notion that everyone needs exactly 64 ounces or two liters of water each day is wrong. Everyone has different hydration needs and should adjust their water intake accordingly based on their activity level and signs of dehydration. Myth: 10,000 steps is the key to getting healthy Sarah Tew/CNET The truth: It's just not. Walking is fantastic exercise; it really is. But walking 10,000 steps a day is not enough to get healthy for most people. Exercise isn't one-size-fits-all, so it just doesn't make sense to blanket the general public with a step recommendation. I don't even get close to 10,000 steps per day (my average is about 4,000), but all my vital signs are healthy and I'm free of disease -- perhaps because I generally eat a healthy diet and meet the recommendations in the Physical Activity Guidelines for Americans. Myth: Six-pack abs are the epitome of health Work your core, but focus on strength over aesthetic. Getty Images The truth: Six-packs are a scam. Having six-pack abs does not make you the fittest person on earth, although it's totally valid to feel that way if you do have them. Forging 12 little divets into your stomach certainly requires hard work in the gym and mindfulness about your diet, but abs are more of a genetic quality than anything else. I, for one, could eat McDonald's once a day and maintain a toned stomach as long as I keep up with my workout schedule -- and I recognize that it's not that easy for everyone. Six-pack abs aren't something you should strive for, anyway, if your body type just doesn't support the goal: For some people, a six-pack means their diet is too restrictive or they're not taking in enough calories overall. Aiming for a strong core over a visible one is a better goal. Myth: Eating saturated fat directly causes heart disease Getty Images The truth: There are more factors to consider. Medical literature still contains much controversy about saturated fat and its relationship to cardiovascular diseases. For decades, public health agencies warned consumers about the dangers of saturated fat, and things really got turned upside-down when a groundbreaking 2017 study boldly proclaimed that saturated fat does not, in fact, clog the arteries. The study also stated that the risk of "bad" LDL cholesterol has been overstated. Since then, the scientific consensus has dissipated, and research about dietary fat and heart health is ongoing. The US Food and Drug Administration still recommends limiting (but not completely avoiding) saturated fat intake in the updated Dietary Guidelines for Americans, and to be safe, it's a good idea to follow their advice. Read more: Keep Your Heart Healthy With These Omega-3 Rich Foods Myth: Organic foods are better for you Getty Images The truth: Evidence is extremely limited. To date, there is just not enough valid scientific evidence that supports organic produce as superior to conventionally farmed produce. Studies have concluded that "there is some evidence for potential benefits of organic food consumption" but "considerable uncertainty/controversy remains on whether or to what extent these composition differences affect human health." Organic produce is subject to different farming practices and tighter regulations than conventional produce (like no synthetic pesticides), but so far, that doesn't mean it's actually more nutritious. Many consumers also believe organic food to be healthier because it isn't produced with synthetic pesticides, but research isn't clear on that, either: One study concluded that "Organic foods convey lower pesticide residue exposure than do conventionally produced foods, but the impact of this on human health is not clear." Another study stated that analyses of human specimens (such as urine) after eating conventional and organic produce showed that there is a possibility that organic foods lower the risk of pesticide exposure, although the clinical implications are unclear. Myth: Natural sugars are better for you than refined sugar All sugar, just in different colors and forms. Getty Images The truth: Sugar is sugar. Coconut sugar, agave nectar, "raw" sugar, palm sugar, evaporated cane juice -- these are all sugar. They just sound healthier because they have fancy names. And hate to break it to you, but molasses and honey are just as bad as sucrose, or table sugar, when they're added to foods (and they still count toward your daily added sugar intake). Your body processes all simple sugars, like those above, the same way. There is one differentiation worth making, though: Sugar in fruit comes along with fiber, vitamins, antioxidants and minerals, which makes it more nutritious than sugar-laden snacks or candy. Myth: Coffee stunts your growth Getty Images The truth: Genetics determine your height. For reasons unknown, this is a wildly common belief. According to Harvard University, "There is no scientifically valid evidence to suggest that coffee can stunt a person's growth." As for any other health risks you believe about coffee, those probably aren't true either: Coffee isn't linked to any medical conditions except for a slight, temporary increase in blood pressure. Myth: GMOs cause cancer GMOs aren't as scary as you might think. Getty Images The truth: No, they don't. Genetically modified crops are just not as scary as they're made out to be -- plain and simple. The wellness world might have you believe otherwise, but there is no scientific evidence that GMOs cause cancer (or any other health problems). A meta-analysis of long-term studies on GMOs concluded that "GM plants are nutritionally equivalent to their non-GM counterparts and can be safely used in food [for people] and feed [for animals]." Plus, they can help farmers decrease pesticide use and increase crop yields and increase food security in developing countries. Science is good. Myth: Microwave ovens cause cancer Getty Images The truth: Nope. Microwaves heat your food: nothing more, nothing less. They do emit electromagnetic radiation, a form of nonionizing radiation similar to the radio frequency waves that come from your cell phone (which also won't give you cancer, by the way), but nonionizing radiation isn't known to cause cancer in humans because it isn't strong enough to alter the structure of cells. Plus, the radiation in microwave ovens is contained within the walls of the appliance, as long as yours is working properly. But even if yours does leak, the FDA imposes a maximum leak requirement on microwave oven manufacturers that is far lower than what would harm people. Myth: Antiperspirants cause breast cancer Putting on deodorant is (hopefully) something we all do everyday. Getty Images The truth: No again. Are we noticing the cancer thing yet? Apparently, everything causes cancer. This myth started coming about in the early 2000s, when studies like this one reported that applying deodorant to cells in a petri dish caused individual cell damage, and aluminum got called out as a potential culprit. But humans apply deodorant to the very outer layer of skin, not to individual exposed kidney cells. A review of studies later determined that aluminum in various forms is not known to cause cancer in humans. The American Cancer Society has also made its statement on antiperspirants and breast cancer: "There are no strong epidemiologic studies in the medical literature that link breast cancer risk and antiperspirant use, and very little scientific evidence to support this claim." Also, the International Agency for Research on Cancer has a handy list of carcinogens classified by level of evidence that a substance can cause cancer, and aluminum is not on the list. Aluminum production is listed, but don't confuse the production of a metal with what is in your deodorant. Myth: Breakfast is the most important meal of the day Eat breakfast, or don't -- whichever you prefer. Getty Images The truth: It's fine to skip breakfast. The world will not end if you skip breakfast. Actually, the science behind intermittent fasting actually suggests that skipping breakfast could benefit you more than eating it. If skipping breakfast suits your lifestyle and your health needs, go for it: Just soothe your hunger before it turns into hanger. Myth: Cold weather causes colds Getty Images The truth: Weather alone cannot make you sick. Ah, a classic case of correlation without causation. Yes, more people get sick when temperatures drop, but cold weather doesn't directly make you sick. Possible explanations include: People spend more time indoors when it's cold out, and viruses spread more easily in close quarters; viruses spread more easily through dry air; and cold weather can temporarily impair your immune system. Myth: Everyone needs eight hours of sleep Getty Images The truth: Everyone is different. Eight is the magic number: Get eight hours of sleep and you'll wake up feeling like a magical forest fairy with boundless energy. For me, this is a big fat myth. I don't wake up feeling ready to leap out of bed unless I snoozed for a solid 10 hours. It's quite annoying, honestly -- I wish I was one of those superheroes who thrived on just six or seven hours of sleep. The point is: Everyone has a unique circadian rhythm that determines how much sleep is optimal for them. While seven to nine hours is still the standard recommendation for adults, you should treat sleep like hydration and exercise: Get enough so that you feel your best and keep your body healthy, but not so much that it starts affecting you negatively. You can always have too much of a good thing, even sleep. Myth: The sun is safer than tanning beds (or vice versa) Getty Images The truth: They both emit UV rays that cause skin cancer. Tanning in the sun and in a tanning bed do the same thing: expose your skin to ultraviolet rays that cause premature aging and are known to cause skin cancer. There are arguments both ways -- the sun is safer, tanning beds are safer, but the American Academy of Dermatology knocks both sides down. Neither is good for your skin. Myth: Cracking your knuckles causes arthritis Getty Images The truth: It's just the release of gases. Your joints may creak, crack and pop, but those noises typically have nothing to do with your risk of arthritis -- usually, it's just the harmless release of gases from synovial fluid, the fluid that lubricates your joints. If you have pain while cracking any joints though (or joint pain in general), it's worth getting checked out by a doctor, because you could have arthritis or another condition, such as tendinitis. Myth: Your body needs juice cleanses Getty Images The truth: Your body cleanses itself. Despite the popularity of juice cleanses to detoxify your body, your liver, kidneys and skin will get the job done on their own. Your body also eliminates waste and impurities through your digestive tract (poop, hello), your lungs and your lymphatic system. In other words, your body is basically one big filter for icky stuff. You can support your body's natural detoxing efforts by eating a healthy diet with minimal processed foods, exercising and working up a sweat, and drinking enough water. Juice cleanses or water fasts can do more harm than good, though: You just deprive your body of essential nutrients, both micro and macro.
