Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized trial comparing small versus large catheters in terms of occlusion and need for replacement to confirm differential occlusion risk based on catheter size. This study will be done to determine whether external ventricular drain catheter diameter has any effect on risk of occlusion.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ventriculostomy is a common neurosurgical procedure. A Nationwide Inpatient Sample (NIS) database study demonstrated a significant increase in ventriculostomy utilization from 1988-2010, with over 35,000 hospitalizations including a procedural code for ventriculostomy in 2010.

Ventriculostomy occlusion is a common complication after external ventricular drain (EVD) placement. A review of published prospective and retrospective studies indicates that approximately 1-7% of EVDs require replacement secondary to occlusion. Furthermore, in the NIS database study of over 101,000 hospitalizations in which ventriculostomy was performed, nearly 6% of patients required at least one additional ventriculostomy procedure. Studies have demonstrated non-patent EVD in 19-47% of patients, however these studies did not prospectively evaluate EVD occlusion as a primary endpoint, report on number of catheter irrigations performed, or identify risk factors for EVD occlusion.

Recently, the investigators completed a retrospective review of a prospectively collected database of patients undergoing bedside EVD placement with the primary outcome of interest being catheter occlusion. This sample included 101 patients over a 1 year period. Two Codman catheters were available for use (Clear Bactiseal 'large' catheter: outer diameter 3.4 mm, inner diameter 1.9 mm; and Orange Bactiseal 'small' catheter: outer diameter 3 mm, inner diameter 1.5 mm). The decision regarding which catheter to use was made at the time of the procedure based on resident preference and availability. Both temporary occlusion (requiring flushing but patency could be restored) and permanent catheter occlusion (requiring replacement) were common, occurring in 41% and 19% of patients, respectively. Over 25% of small catheters became occluded during the study period compared to 11% of large catheters. Small catheters were associated with a 3.4 times greater odds of occlusion than the larger diameter catheters on multivariable regression analysis. This study suggests that the preferential use of larger diameter catheters may reduce the risk of ventriculostomy occlusion and need for replacement, however the study was not randomized and catheter selection may have been biased.

Recently, a smaller retrospective study of patients with intraventricular hemorrhage performed by Gilard and colleagues demonstrated a lower rate of occlusion and no increased risk of hemorrhage with larger bore catheters. Otherwise, there is no data in the literature supporting the preferential use of catheters based on size (clinical equipoise).

Clear Bactiseal 'large' catheter (EVD)

All EVDs will be placed by neurological surgeons in either the major operating suite or in an ICU setting using a previously published protocol. This protocol includes using a burr hole entry point 1 cm anterior to the coronal suture in the mid-pupillary line, prep and sterile drape, pre-procedural antibiotic administration, and tunneling the catheter to an exit site at least 5 cm from the incision. In general, physicians are instructed to first attempt distal irrigation of the drainage chamber using sterile techniques (rarely effective), followed by gentle aspiration of the proximal system and catheter if distal flushing is not effective. If these do not restore patency, a small volume of sterile saline, 3 ml or less, is flushed proximally into the catheter. Patency is checked by lowering the EVD drainage system and evaluating for spontaneous flow through the EVD.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adult patients (18-85 years old) with a Glasgow Coma Scale (GCS) score of 7 or higher requiring frontal EVD placement.
* Diagnoses: spontaneous subarachnoid hemorrhage, intraventricular hemorrhage, intraparenchymal or cerebellar hemorrhage due to aneurysm, arteriovenous malformation, arteriovenous fistula, hypertension, or idiopathic etiology.
* Also included are patients for whom the attending neurosurgeon decides that frontal EVD placement is indicated for patient treatment with planned cerebrospinal fluid (CSF) drainage for 72 hours or more.

Exclusion Criteria

* GCS of 6 or less
* Hunt and Hess subarachnoid hemorrhage grade of 5.
* Age 86 or greater, or age 17 or less.
* Patient cannot consent and next of kin cannot consent prior to procedure.
* Diagnosis of traumatic brain injury, as the EVD is often clamped for extended periods of time.
* Patients anticoagulated prior to admission with warfarin, Effient, Plavix, therapeutic heparin infusion, therapeutic subcutaneous lovenox, therapeutic subcutaneous arixtra, or other therapeutic anticoagulant or antiplatelet agent (ASA not included).
* Plan for EVD placement through non-frontal burr hole.
