Antibiotic-impregnated external ventricular drainage for the management of post-hemorrhagic hydrocephalus in low birth weight premature infants following intraventricular hemorrhage.

Purpose: This study aims to evaluate the infection rates and catheterization duration of applying antibiotic-impregnated external ventricular drain (EVD) for the treatment of post-hemorrhagic hydrocephalus (PHH) in low birth weight infants (LBWI). Methods: This retrospective cohort study included 13 preterm LBWI with PHH. Data were collected from the patient's medical charts and included gender, gestational age, birth weight, intraventricular hemorrhage grade, ventriculostomy-associated infection (VAI), and the duration of catheterization. All patients were followed up for at least 6 months after EVD surgery. Results: The mean gestational age at birth was 27 ± 2.5 weeks, and the mean birth weight was 907 ± 220 g. Among all patients with IVH, two (6.7%) had grade 2 IVH, five (38.5%) had grade 3 IVH, and six (46.2%) had grade 4 IVH. EVD surgery was conducted once for six patients, twice for five patients, and three times for two patients. One patient (7.7%) had VAI post-EVD surgery at 14 days. Three patients (23%) expired due to sepsis, shock, and chylous ascites. Seven patients (53.8%) had hydrocephalus and needed a ventriculoperitoneal shunt over the following course. The longest EVD catheterization period was 57 days without sustained VAI. Conclusions: Antibiotic-impregnated EVD has a similar infection rate with the ventricular access device and ventriculosubgaleal shunt. The risk of VAI was not increased even with the EVD catheterization day approaching 2 months. Our study supports the evidence that antibiotic-impregnated EVD is safe and effective for the management of PHH in LBWI. However, this research has a small sample sized and a retrospective design.
