Going bananas trying to figure out this answer,can't find it. It's all so new, finished core last year, start again one week from now,and I'm trying to get a head start.
could anyone tell me which one doesnt require a sterile technique
1. surgical wound dressing change.
2. insertion of foley catheter
3. changing a solution bag on an intravenous infusion.
OK. Let me backtrack a bit. I am sorry if I've created confusion. I've used the term "sterile technique" a little too loosely and should instead have said, "maintain sterility."
Let me explain my initial reasoning, then I'll answer the question again, taking into account all of the previous comments.
My initial response to the above question was #1 because by and large, surgical wound dressings are NOT sterile. As we've already discussed, the wound and the surrounding skin under the dressing are not and never have been sterile. Going to the time and expense of doing a surgical dressing change under sterile technique is usually unnecessary and does not produce any better results in terms of infection control or healing than simply using clean technique. My rationale for choosing #1 as the correct answer was that failing to maintain sterility of a Foley catheter or an IV infusion most definitely puts a patient at risk for infection, while changing a surgical dressing using non-sterile (clean) technique does not.
There are exceptions in which a surgical dressing change should be done under sterile conditions. For example, when a surgical procedure is performed to insert a device which will remain partially outside the body (a central venous line or a peritoneal dialysis catheter, for example) the dressing must be maintained using sterile technique to prevent micro-organisms from ascending the object into the body. Another example would be a procedure in which internal organs or tissues are not fully replaced into the body (gastroschisis repair in a newborn, in which it is not possible to place all of the intestines into the abdominal cavity.) In this example, the dressing (usually a silo) must be maintained using sterile technique to lessen the risk of infection until the abdominal wall can be closed. A third example would be dressings for extensive burns. When healthy skin is no longer available to protect against infection, extra precautions in dressing changes are necessary to protect the vulnerable patient from infection. But these examples are the exceptions, not the rule. Most surgical dressings from abdominal, orthopedic, laparoscopic and other general surgical procedures are not and do not need to be maintained under sterile conditions.
Now, on to my revised answer. linnaete asked, "Doesn't sterile technique require sterile gloves and sterile field? I think I'm more confused now lol.... " That made me realize that I may be confusing the term "sterile technique" with maintaining the sterility of an object. If "sterile technique" refers to the process of gowning, masking and gloving in order to prepare a special sterile field in which to carry out a sterile task, then my answer would be #3. This would be the procedure in which it would be posible to maintain the sterility of the object being used (IV tubing) without donning sterile garb and establishing a sterile field.
Whew! A very long winded answer that reminds me of why I enjoy the student forums. You guys made me think!
