Frequency of External Ventricular Drain Related Infection

Objective: To evaluate the frequency of external ventricular drain (EVD) related infections. Material and Methods: This observational study was conducted at the department of Neurosurgery / pathology, Postgraduate medical institute, Lady Reading Hospital Peshawar from July 2014 to December 2014. A total of 18 consecutive patients, who undergone EVD, irrespective of their age and gender were included in the study. Those who had intracranial infection, Cerebrospinal fluid leak (CSF) or revision of EVD (external ventricular drain) were excluded from the study. Results: We had total 18 patients who underwent EVD in the study period. There were 44.4% males and 55.6% females. Their age range was from 1-69 years with the mean age of 40years. Main indication for EVD was intracranial hemorrhage in 55.6% cases. Post EVD infection was observed in 16.6%. Conclusions: We conclude that external ventricular drainage is an effective and quick technique for the management of acutely raised intracranial pressure with dilated ventricular system. The incidence of EVD related infection is significant (16.6%). Early diagnosis is made on the basis of CSF culture, gram staining and routine evaluation for increased white cell count, increased proteins and decrease glucose level. This will help to permit immediate and specific treatment
