ABSTRACT

background. Hydrocephalus occurs when there is an imbalance between the production and absorption of cerebrospinal fluid (CSF). The most effective and simple treatment is to divert the excess of CSF.
material and methods. A case-control study was conducted. A retrospective review was made of the medical records of all patients who underwent a ventriculo-peritoneal shunt insertion at the Sinaloa Children´s Hospital between January 1, 2007 and December 31, 2012.
results. Sixty two ventriculoperitoneal shunts were inserted; 16 patients (25.8%) developed shunt infection. The risk factors that had an OR greater than 2 in the univariate analysis were: surgical time greater than 60 minutes (OR = 3.545, 95% CI = 0.885-14.199), undergoing ventriculoperitoneal shunt insertion before the first year of life (OR = 2.368, 95% CI = 0.735-7.631) and that the patient has been hospitalized for more than 10 days after shunt insertion (OR = 3.182, 95% CI = 0.967-10.473). It was considered that any of the variables had significance since the p value was greater than 0.05 in all cases. The microorganisms isolated were coagulase-negative Staphylococcus (50%), Enterococcus faecalis (25%) and Enterobacter cloacae (25%).
conclusion. The percentage of patients with infection associated with ventriculoperitoneal shunt insertion in our hospital is high, which indicates the need and importance of implementing more strict preventive measures.
