Content, Quality, and Dissemination Characteristics of Information on Combined Spinal-Epidural Anesthesia and General Anesthesia on Short-Video Platforms: A Cross-Sectional Study
This cross-sectional study evaluates the quality and dissemination of combined spinal-epidural and general anesthesia videos on TikTok, Douyin, and Bilibili, revealing generally low-to-moderate content quality, significant platform heterogeneity, and a strong positive correlation between engagement and audiovisual appeal rather than evidence-based rigor, with medical personnel producing notably more reliable content.

Imagine you are standing in a bustling digital town square, a place where everyone from doctors to your neighbor's cousin is shouting advice about how to survive a major life event. In this case, the event is surgery, and the advice is about the "sleepy juice" (anesthesia) that keeps you safe and pain-free while the doctors work. For decades, the gold standard for this information was a quiet, one-on-one chat with your anesthesiologist. But today, the town square is dominated by short, snappy videos on apps like TikTok, Douyin, and Bilibili. These platforms are like giant, fast-moving conveyor belts of information. Some videos are made by experts who know the science inside out; others are made by people sharing their own scary or exciting stories. The big question is: if you are nervous about your upcoming surgery, which videos should you trust? Are the most popular videos the most accurate ones, or are they just the most entertaining? This study dives into that exact chaos, comparing two common types of anesthesia—Combined Spinal-Epidural (CSEA), often used for things like C-sections where you stay awake but numb, and General Anesthesia (GA), where you are completely asleep—to see what kind of information is actually floating around the internet.
The researchers, Jing Zhang and her team, decided to take a deep dive into this digital ocean. They didn't just guess; they went out and collected 428 videos from three major platforms: TikTok, Douyin, and Bilibili. They looked at videos talking about both CSEA and General Anesthesia. To make sure they weren't just looking at the "viral" stuff, they used three different "report cards" to grade the videos. One card checked if the information was reliable and backed by science (mDISCERN), another looked at how good the video was as a whole teaching tool (GQS), and a third judged how clear and well-made the video was (VIQI). They also counted how many people liked, shared, commented on, or saved each video to see what was actually popular. They even sorted the creators into two teams: the "Medical Pros" (doctors, nurses, pharmacists) and the "Non-Medical Crew" (patients, family members, and regular folks).
Here is what they found, and it's a bit of a plot twist. First, the "Quality-Popularity Paradox." On TikTok, the videos got absolutely massive amounts of attention. For CSEA videos, TikTok had a median of 4,288 likes, while Bilibili had only 43.50. That's a huge difference! But here's the catch: the videos that got the most likes weren't necessarily the ones with the best medical advice. The study found that the "popularity" of a video was strongly linked to how good it looked and sounded (the VIQI score), not necessarily how scientifically rigorous it was. It's like a magic show: the trick that gets the biggest applause isn't always the one that teaches you the most about physics. In fact, for General Anesthesia videos, the most reliable scientific info (mDISCERN score) had almost no connection to how many likes it got.
Second, the platform mattered a lot. TikTok was the king of engagement, but it was also a bit of a mixed bag when it came to quality. Bilibili, which is known for longer, more educational content, actually had the lowest quality scores for CSEA videos in this study, mostly because almost all the CSEA videos there were made by non-medical people. Douyin sat somewhere in the middle. The study suggests that the algorithms on these apps are like bouncers at a club; they let the flashy, emotional, and fast-paced videos in, while the dry, super-accurate medical lectures often get stuck at the door.
Third, and perhaps most importantly, the "Who" matters more than the "What." The researchers found a clear divide between the two teams. Videos made by medical personnel (doctors and nurses) were significantly more reliable and higher quality than those made by non-medical people. For CSEA videos, the medical pros scored much higher on the reliability and quality scales. For General Anesthesia, the medical pros also won, though the gap in "overall teaching quality" was a bit smaller. The study explicitly rules out the idea that a high number of likes means you have found the best advice. It suggests that relying on the "viral" count is a trap.
So, what's the takeaway for a curious teenager or anyone facing surgery? The internet is full of anesthesia videos, but they are a mixed bag of low-to-moderate quality. The most popular videos are often the most entertaining, not the most accurate. The most reliable voices are the medical professionals, but they aren't always the ones getting the most views. The authors suggest that we need to be careful: don't just watch the video with the most likes. Instead, look for the badge that says "medical professional," and remember that online videos should only be a warm-up act, not the main event. The real decision about your anesthesia should happen in a quiet room with your actual doctor, where you can ask questions and get answers that aren't just trying to get a million views. The study concludes that while the current online landscape is a bit chaotic, there is a clear path forward: medical experts need to make more videos, platforms need to help highlight the good ones, and we all need to be a bit more skeptical of the flashy stuff.
