Remove the gloves by turning them inside out, making sure that you do not touch the outside (contaminated) surface with your ungloved hands. Roll up the gown with the contaminated surface facing inward and away from you ( Figure 2-6C). Take off the gown by turning it inside out as it is removed ( Figure 2-6B). Have an assistant untie the neck strings of the gown or pull on both shoulders of the gown to break the neck strings. The first step is to untie the gown ( Figure 2-6A). Place all removed garments into appropriate waste containers. Remove protective clothing in a systematic manner in order to protect yourself and others from the contaminants on your gown and gloves ( Figure 2-6). Adjust each glove to ensure a snug fit over the fingers and hand. Carefully unfold the cuff of each glove, taking care not to touch the fingers and palms of the gloves to nonsterile skin. Pull this glove over the dominant hand using the cuff ( Figure 2-5I). Slip the dominant hand into the glove ( Figure 2-5H). Place the fingers of the gloved nondominant hand into the folded cuff of the other glove ( Figure 2-5G). Pull the glove further onto the nondominant hand using the inner edge of the cuff ( Figure 2-5F). Slip the nondominant hand into the glove, being careful not to touch the outer surface of the glove ( Figure 2-5E). Use the dominant hand to grab the opposite glove at the inner edge of its folded cuff ( Figure 2-5D). Apply a sterile gown at this point if it will be worn during the procedure. Open the inner wrap according to the procedure for opening a sterile pack ( Figure 2-5C). Unfold the inner wrap, touching only the outside edges ( Figure 2-5B).
Place the inner wrap on a clean surface with the gloves' wrists facing toward you. Open the outer wrap of the sterile gloves and remove the inner wrap ( Figure 2-5A). Apply a clean gown at this point if it will be worn during the procedure. Wash your hands thoroughly before putting on sterile gloves. Repeat the procedure if the pack has an inner wrap. Make sure that your arms and clothes do not contaminate the contents of the pack when opening the flaps. Grasp and open the bottom flap while stepping back to prevent contaminating the wrap on your clothing ( Figure 2-2E). Open the side flaps by grasping the folded corner with a thumb and index finger and pulling the flap to the side ( Figure 2-2C). Lift the flap up and away from you ( Figure 2-2B). Hold your arms to the sides of the pack to avoid reaching over the sterile area. Grasp the corners of the outermost flap ( Figure 2-2B). Place the sterile pack on a dry and level surface with the outermost flap facing away from you ( Figure 2-2B).
Remove the sterility indicator tape ( Figure 2-2A). 2 Wash your hands and then remove the outer wrap if applicable. Always make sure that the outer wrapping is intact, the sterility expiration date has not passed, and the sterility indicator tape is the appropriate color before opening a sterile pack.
