<blockquote>Hey Guys, I got a fun Medical Question for you all and maybe a little bit more aimed towards Dr. Novella due to his medical background. If you've seen the new season of the Walking Dead (spoilers), in the first episode the old guy gets bitten on the leg and the main character decides to amputate his leg because he thinks it's like a venomous snake bite. The rationale is even though they all know they're all infected already, that zombie bites cause a secondary infection that makes you sick and you die thereby allowing the primary infection to turn you into a zombie. Is the choice to amputate really stupid even if the infection was like a venomous bite? You would think they made a relatively moderate problem of a huge bite into an enormous problem given that there's going to be massive blood loss now, chance of incidental infection, and well....the old guy is really old and he probably can't take the shock of getting his leg hacked on repeatedly by a handaxe. If they intended to cauterize the amputation later, wouldn't it have been better to just cauterize the huge bite wound instead and hope that would be enough? It seems like anything they could do to help the amputation they've could have done to the bite wound and it wouldn't have been as bad. Dr. Novella has talked about in medicine that usually treatments have risks but the benefits outweigh the risks. In this case I'm wondering if the Amputation is causing more damage than it's helping, given their fictional situation. Thanks, Henry Loo</blockquote> | <blockquote>Hey Guys, I got a fun Medical Question for you all and maybe a little bit more aimed towards Dr. Novella due to his medical background.

Zombie Bite (44:36)
Hey Guys, I got a fun Medical Question for you all and maybe a little bit more aimed towards Dr. Novella due to his medical background. If you've seen the new season of the Walking Dead (spoilers), in the first episode the old guy gets bitten on the leg and the main character decides to amputate his leg because he thinks it's like a venomous snake bite. The rationale is even though they all know they're all infected already, that zombie bites cause a secondary infection that makes you sick and you die thereby allowing the primary infection to turn you into a zombie. Is the choice to amputate really stupid even if the infection was like a venomous bite? You would think they made a relatively moderate problem of a huge bite into an enormous problem given that there's going to be massive blood loss now, chance of incidental infection, and well....the old guy is really old and he probably can't take the shock of getting his leg hacked on repeatedly by a handaxe. If they intended to cauterize the amputation later, wouldn't it have been better to just cauterize the huge bite wound instead and hope that would be enough? It seems like anything they could do to help the amputation they've could have done to the bite wound and it wouldn't have been as bad. Dr. Novella has talked about in medicine that usually treatments have risks but the benefits outweigh the risks. In this case I'm wondering if the Amputation is causing more damage than it's helping, given their fictional situation. Thanks, Henry Loo
