Things we can learn from the video
Press to jump
- 5:01Barber-surgeons practiced bloodletting within a medical system built around balancing bodily humors.
- 14:14Before anesthesia, surgeon Robert Liston's reputation rested partly on the speed of his amputations.
- 32:40Fitzharris explains how Joseph Lister developed antiseptic surgery using carbolic acid.
- 37:51Joseph Bell's diagnostic observation helped inspire Sherlock Holmes, the subject connecting Fitzharris's book with the interview.
- 50:09Harold Gillies developed reconstructive techniques for soldiers with facial injuries during World War I.
Joseph Bell taught medical students to read a patient's body like a crime scene. That makes him a particularly fitting guest of honor, historically speaking, in Doctor Mike's conversation with medical historian Dr. Lindsey Fitzharris.
"What Surgery Was Like In The 1800's | Dr. Lindsey Fitzharris" stretches from barber-surgeons and bloodletting to antiseptics and reconstructive surgery. Around the halfway mark, Fitzharris introduces the subject of her book Sleuth-Hound: Bell, whose powers of observation helped inspire Sherlock Holmes. Diagnosis and detective work turn out to have quite a bit to discuss.
The interview is the most-watched of Doctor Mike's three new uploads, approaching 400,000 views. Its length has become part of the conversation, too: one viewer reports getting an entire house-cleaning session out of it, while others ask for another Fitzharris appearance or discuss her books.
The other releases return to familiar reaction territory: "Doctor Mike Reacts To 1000 Medical TikToks | COMPILATIONS" and "What Paramedics See at 3 AM Is Terrifying." The paramedic upload is already close to the interview's total and currently draws the most daily views on the channel. Fitzharris also appears in the previous week's "The Worst Medical Devices In History," which continues to attract substantial viewing.
Across the channel, the week brought roughly 20 million views, with subscribers unchanged. Daily viewing is now less than half its usual level. Among nearby health channels, Dr. Eric Berg DC had a similarly substantial weekly audience, while Dr. Tracey Marks added subscribers. For Doctor Mike, the distinctive addition is a long conversation that makes room for both the operating theater and Sherlock Holmes.
