Risk of infection after placement of an extraventricular drainage catheter

Abstract

Introduction. The occurrence of infection after the placement of an extraventricular drainage (EVD) catheter can be a very serious problem in neurosurgery. Objective. The aim of this study was to confirm that the use of special catheters with impregnated antibiotics decreased the percentage of infection. Methods. The prospective study conducted at the Clinic of Neurosurgery in Nis in the period 2006-2009 is presented. Group 1 comprised of 43 patients in whom a commonly used system for EVD was applied. Group 2 comprised of 39 patients in whom the Rifampycin and Clindamycin impregnated EVD catheters were applied (Bactiseal catheters). Results. In Group 1 infection occurred in nine patients, mainly caused by bacteria of Staphylococcus genus. In Group 2 only two patients developed infections caused by Acinetobacter. Conclusion. The use of Bactiseal EVD catheters considerably decreased the percentage of infection occurrence with prolonged EVD catheter drainage period.Uvod. Infekcija nakon postavljanja katetera za ekstraventrikularnu drenazu (EVD) moze biti veoma ozbiljan problem u neurohirurgiji. Cilj rada. Cilj rada bio je da se ispita da li se primenom posebne vrste katetera za EVD smanjuje procenat nastanka infekcije. Metode rada. Prospektivna studija je izvedena u periodu 2006-2009. godine na Klinici za neurohirurgiju Klinickog centra u Nisu. Ispitana su 82 bolesnika, koja su svrstana u dve grupe. Grupu 1 cinila su 43 bolesnika kod koja je postavljen obican sistem za EVD, dok je grupa 2 obuhvatila 39 bolesnika kod kojih su korisceni kateteri za EVD impregnirani antibioticima (rifampicinom i klindamicinom - Bactiseal kateteri). Rezultati. U grupi 1 infekcija se razvila kod devet ispitanika i najcesce je bila izazvana bakterijama roda Staphylococcus. U grupi 2 samo je u dva slucaja doslo do razvoja infekcije, izazvane bakterijom Acinetobacter. Zakljucak. Upotreba Bactiseal katetera za EVD znacajno je smanjila procenat pojave infekcije uz produzenje broja dana postavljanja EVD.
