#Topical antibiotics may raise pneumonia risk University of Melbourne rightoriginal Studyposted by David Scott-Melbourne on October 13 2014patients in hospital intensive care units have a higher risk of developing pneumonia when they are treated with topical antibiotics. The findings contradict previously published research that topical antibioticsâ##medication applied to the patient s airwayâ##would decrease pneumonia rates. Ventilator-associated pneumonia develops in approximately 20 percent of patients in intensive care units (ICUS) who are receiving prolonged medical ventilation. However in the control groups of these published clinical trials of topical antibiotics in this patient group the pneumonia rates were as high as 40 percent. For a new study published in the journal CHEST researchers analyzed 206 international publications evaluating pneumonia prevention methods in ICUÂ##s from the last 30 years. The new findings will help improve understanding of how to evaluate pneumonia prevention methods in the ICU says associate professor James Hurley from the University of Melbourne. Use of topical antibiotics increases the pneumonia risk in ICU patients by disrupting the balance of bacteria not only in patients that received these antibiotics but also in control group patients also staying in the ICU.####This changed flora is spread around the ICU environment to other patients through cross-infection##Hurley says.####This surprising finding is not apparent in any one study examined in isolationâ##it requires a meta-analysis of the control group pneumonia rates in all 206 studies to demonstrate these findings. Pneumonia is acquired commonly by ICU patients leads to longer stays in intensive care and can also increase mortality risk.#####Therefore it appears topical antibiotics used in an effort to prevent pneumonia in the ICU are a hazard and the method is unsafe.####Source: University of Melbourneyou are free to share this article under the Creative Commons Attribution-Noderivs 3. 0 Unported license o
