About Lisa

I have been a Clinical Informationist (aka Medical Librarian) for Emory University since September 2013. Prior to that, I was a Medical Librarian for Lincoln Memorial University (LMU) from March 2007 to August 2013 and served its DeBusk College of Osteopathic Medicine (LMU-DCOM), Caylor School of Nursing, and allied health programs. From January 2002 - March 2007, I served the Medical Assisting (MA), Occupational Therapy Assistant, Physical Therapy Assistant, Radiologic Technologist, and Nursing programs at South College in Knoxville, Tennessee. I graduated from The University of Tennessee School of Information Sciences with a Master of Science degree in December 2000. Received a Educational Specialist (EdS) degree in Educational Administration and Supervision with a higher education focus in August 2010 from LMU.

Should capnography be used in postoperative, unventilated patients?

There isn’t a consensus on whether capnography should be used in postoperative patients.

Eichhorn, John H. “Review article: practical current issues in perioperative patient safety.” Canadian journal of anesthesia 60.2 (2013):111-118.
The first paragraph of page 116 discusses the lack of consensus on how best to monitor postoperative patients for hypoventilation from postoperative pain medication.

Jarzyna, Donna, et al. “American Society for Pain Management Nursing guidelines on monitoring for opioid-induced sedation and respiratory depression.” Pain management nursing 12.3 (2011):118-145.e10.
Article states, “there is a paucity of information and no consensus about the benefits of technology supported monitoring, such as…capnography.”

Hutchison, Rob, and LesRodriguez. “Capnography and respiratory depression.” American journal of nursing 108.2 (2008):35-39.
This randomized prospective study of 54 postoperative orthopedic patients found a significantly higher rate of respiratory depression in the capnography group, concluding that “capnography may be more appropriate for use with postsurgical high-risk patients taking opioids” and “may have the added advantage of indicating those patients who may be at risk for obstructive sleep apnea.”

Should needleless caps be changed before drawing blood samples?

Mathew, Alice, et al. “Central catheter blood sampling: the impact of changing the needleless caps prior to collection.” Journal of infusion nursing 32.4 (2009):212-218.
This study of 91 patients compared 3 methods of blood draws (old cap (existing cap), new cap (replacing old cap with a sterile one), and peripheral methods).  Nine false positive cases of bacteremia were identified using the old cap. Researchers recommending changing the cap before drawing culture samples.

 

Does changing needleless caps reduce the rate of infections?

Conflicting evidence exists on whether changing needleless caps reduces the rate of infections.

Do, A N, et al. “Bloodstream infection associated with needleless device use and the importance of infection-control practices in the home health care setting.” The Journal of infectious diseases 179.2 (1999):442-448.
Cohort study found that rate of bloodstream infections (BSIs) rate “decreased as the frequency of changing the needleless device end cap increased from once weekly up to every 2 days, suggesting that the mechanism for BSI may involve contamination from the end cap.”

McDonald, L C, S N NBanerjee, and W R RJarvis. “Line-associated bloodstream infections in pediatric intensive-care-unit patients associated with a needleless device and intermittent intravenous therapy.” Infection control and hospital epidemiology 19.10 (1998):772-777.
Bloodstream infection (BSI) rates increased in patients receiving “intermittent (vs continuous) intravenous therapy through one or more lumens. The IVAC device valvecomponent was replaced every 6 days, and the endcap used to cover the valve (when connected to an unused lumen) was replaced every 24 hours or after each access. The BSI rate returned to baseline after institution of a policy to replace the entire IVAC device, valve, and endcap every 24 hours.”

Danzig, L E, et al. “Bloodstream infections associated with a needleless intravenous infusion system in patients receiving home infusion therapy.” JAMA: the Journal of the American Medical Association 273.23 (1995):1862-1864.
Researchers conducted case-control and retrospective cohort studies. Data found that needleless device used for total parenteral nutrition and intralipid therapy (TPN/IL) “was associated with increased risk of BSI when injection caps were changed every 7 days.”
