What technique is essential during suctioning of a tracheostomy tube to prevent infection?

• A. Sterile technique
• B. Clean technique
• C. Standard precautions
• D. Personal protective equipment

Answer: (A)

During suctioning of a tracheostomy tube, the airway is directly exposed to the outside and a sterile field must be maintained to prevent introducing bacteria into the lower respiratory tract. The trachea is a normally sterile area, so using sterile technique—sterile catheter, sterile gloves, and a sterile setup—helps keep the environment free of pathogens and reduces the risk of pneumonia or tracheal infections. Clean technique isn’t enough for this invasive airway procedure because it doesn’t guarantee sterility. Standard precautions and personal protective equipment are important for safety in general but don’t by themselves ensure a sterile field during this invasive procedure.
