What is the correct method for surgical skin prep for a right arm disarticulation at the shoulder?

The correct method for surgical skin prep for a right arm disarticulation at the shoulder involves beginning at the shoulder and progressing to the fingertips, while ensuring that the axilla (armpit) is prepped last.

This approach is essential for several reasons. First, starting at the shoulder allows for optimal cleansing of the most proximal part of the surgical site, reducing the risk of contamination from debris or bacteria that may be present on the skin. The axilla is often a site of increased microbial flora, and prepping it last minimizes the chance of bacteria migrating down to the surgical field after it has been prepped. Additionally, including the flank and chest regions acknowledges that the procedure may have anatomical considerations that require a broader prep area to account for potential overlap with the surgical site.

By following this sequence, the surgical team can maintain a sterile environment and reduce the likelihood of postoperative infections. This method aligns with standard surgical protocols that emphasize thorough and careful preparation of the skin surrounding the operative site.
