What is one of the outcomes of Joseph Lister's antiseptic techniques in surgery?

Joseph Lister's introduction of antiseptic techniques had a profound impact on the field of surgery, particularly concerning patient safety and outcomes. By implementing methods to sterilize surgical instruments and ensure a clean operating environment, Lister significantly reduced the occurrence of post-surgical infections. This advancement led to improved patient survival rates during operations, as infections that previously resulted in severe complications or death were drastically lessened.

The other options do not reflect the actual outcomes associated with Lister's theories. For instance, increased rates of infection contradict the very purpose of antiseptic procedures. Similarly, while some surgical methods became less necessary as surgical techniques advanced, it wasn’t directly a result of Lister's work. Lastly, although antiseptic methods may have initially increased costs due to the need for more meticulous care and materials, the outcomes in terms of success rates and patient recovery far outweighed any financial implications. Thus, option B accurately captures one of the significant achievements of Lister's pioneering work in surgery.
