Abstract

This is a prospective study that was conducted over a period of one year ( 1 1/05 to 1 1/06) in a private hospital in Guatemala City. We determined the frequency and possible risk factors for infections associated with central venous catheters, and infectious agents commonly involved with their antibiotic susceptibility patterns. To do this, we followed up all patients that were placed with central venous catheters, through a data sheet and grown all the tips that were sent to the laboratory for medical decisions, Supplemented Maki thioglycol late broth was used for the culture technique. We withdrew a total of 122 catheters from 85 patients, however, only 87 catheters were used for the study, they were divided into four groups according to the number of catheters used in each patient; 57 corresponded to the first catheter that was placed in each patient, so they were analyzed separately. There weren't a second catheter analysis forward because there were few samples. We calcuíated the frequencies and associations, using ECXEL. Wc determined the value of chi square, p EPIDAT and using the frequency and patterns of bacterial susceptibility WHONET program.

No statistically significant association was found between the results of culture oí the catheter with age, sex, duration of catheterization, catheter number of keys, use of other invasive way, suffering from systemic disease and use of systemic antimicrobial therapy (all p> 0.05). There was a significant association between the site of catheter placement and the culture result, with increasing frequency in the right jugular position, ( 4 of 4). The most frequent organism that isolated from catheters was Staphylococcus epidermidis (24%) and the percentage of bacteremia was 1.14%.

We conclude that the percentage of colonization obtained in the study was relatively low compared with previous studies (8, 9, 11) in Guatemala, however, is considered to be high (20.69%) for the present study, compared with international standards. No significant relationship was found between duration of catheterization and infection, probably because the number of cases studied (p = 0.71 55).
