Brief summary
The purpose of this study is to determinate if 70% isopropyl alcohol is not inferior preventing contamination of peripheral hemocultures, compared with 2% chlorhexidine in 70% isopropyl alcohol.
Detailed description
The develop of contaminants in blood cultures is a problem of great impact to health institutions and patients, as they represent a waste of resources, and additionally increases the patient's hospital stay. The principal source of contaminant is the bacteria in the skin flora, so the greatest way to improve the sensibility of this test is to do an optimal skin antisepsis. It has been reported that 2% chlorhexidine gluconate in 70% isopropyl alcohol is superior that other skin disinfectants, and that 70% isopropyl alcohol has a high efficacy reducing the presence of bacteria on the skin, so both antiseptics are good options for skin antisepsis.
Interventions
BIOLOGICALchlorhexidine in isopropyl alcohol
When a hemoculture is ordered, the laboratory technician will prepare the necessary materials for venipuncture. Previously the technician must take randomly a sealed envelope, where will be writing the antiseptic to be used for antisepsis. The technician will select a site for venipuncture, preferably in the forearm, and will do the antisepsis in the site selected, letting act the substance for 45 seconds. After this procedure, the venipuncture shall be done. The sample will be cultured for 120 hours at 35 +/- 2°C.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Determine if 70% isopropyl alcohol is not inferior preventing contamination of peripheral hemoculture, compared with 2% chlorhexidine in 70% isopropyl alcohol. | 120 hours | It will determine the growth of contaminating germs in hemocultures taken with each antiseptic tested. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Determine the rate of contamination of each antiseptic used. | 1 year | It will determine the rate of contamination at the date of primary completion and the date of study completion. We will consider contaminants the development of Staphylococcus coagulase negative and gram positive bacilli. |
