During suturing, needles are passed and returned one for one: the surgeon hands back the used needle, still on its needle holder or on the neutral zone mat, as the next loaded holder is received. The returned needle goes straight onto a magnetic pad or needle counter on the back table, where it can be seen and counted. This keeps every needle accounted for through the closure and lowers the risk of needlestick injury from loose needles on the drapes.

Takeaway. Needles are exchanged one for one, and each returned needle goes onto the needle counter.

Open gloving is the method for sterile work that needs no gown, for example a skin prep or a urinary catheterization. The glove's cuff is folded back, so the outer surface of the fold is actually the inside of the glove. The bare hand picks up the first glove only by that folded cuff, then the gloved fingers go beneath the second glove's fold so they meet only its sterile outside.

Takeaway. Bare skin touches only the turned-down cuff, the glove's inside; gloved fingers go under the second cuff.

Tissue or fluid suspected of infection is cultured to identify the organism and to find which antibiotic it is sensitive to. Aerobic and anaerobic studies are often both ordered, each in its own transport container, so the scrub has both kinds of tube ready when an abscess or infected tissue is opened. Anaerobic bacteria die quickly when exposed to air, so the swab is placed into its growth medium or transport tube immediately. Culture specimens are never put in formalin, and they are labeled and sent to the laboratory promptly.

Takeaway. An anaerobic culture swab goes into its own transport tube at once, because air kills anaerobes.

Plaster stays soft for some time after it is applied, and any local pressure molds the inside of the cast into the skin. A dent made by a fingertip becomes a ridge that can cause a pressure sore under the cast. While it sets, the cast is handled only with the palms of open hands and rested on a pillow or padding rather than a hard edge.

Takeaway. Handle a wet plaster cast with open palms only, never fingertips.
