Effects of Disinfection According to Durations of Surgical Hand Scrub and Type of Disinfectant / 기본간호학회지

PURPOSE: This study was done to identify the differences in effectiveness of disinfections for surgical hand scrubbing according to the duration of scrubbing and the type of disinfectant. METHOD: From June 30 to August 14, 2003, the data were collected from 30 surgical nurses and surgeons in one general hospital in P city, Korea. All participants washed their hands with two different disinfectants and four different scrubbing times, they placed both finger tips on a blood agar plate and using sterile cotton tips microbes were collected from their palms, nails and forearms. RESULTS: The first hypothesis of this study(with same disinfectant, there will be no difference in effect of disinfection in surgical hand scrub among four time groups) was supported. The second hypothesis of this study(with same duration of surgical hand scrub, there will be no difference in effect between two disinfectants) was also supported. CONCLUSION: There are no differences in effectiveness of disinfection for surgical hand scrubbing according to duration of the scrubbing and the type of disinfectant. So it is concluded that the effectiveness of disinfection depends more on the exactly how the scrubbing is done rather than the duration of scrubbing or the type of disinfectant.

Multiplane Transesophageal Echocardiographic Findings of Two Cases of Discrete Subvalvular Aortic Stenosis

Discrete subvalvular aortic stenosis is a relatively uncommon cause of the left ventricular outflow obstruction, requiring early intervention. Conventional transthoracic echocardiography may fail in some patients due to insufficient imaging quality. In particular, in patients with a discrete fibrous membrane close to the aortic valve without narrowing of the left ventricular outflow tract, the echocardiographic detection of the membrane may be difficult. Transesophageal echocardiography allows a clear visualization of the aortic valve and the left ventricular outflow tract in virtually all patients, it can be performed rapidly with almost no risk, and it may therfore be helpful in establishing the diagnosis of discrete subaortic stenosis, in particular in patients where the conventional transthoracic approach fails. We have experienced two cases of discrete subaortic stenosis. One case of them was combined with hypertrophic obstructive cardiomyopathy in this report we discussed the utility of multiplane transesophageal echocardiography in patients with discrete subvalvular aortic stenosis.
