External ventricular drains (EVDs) are commonly used to facilitate removal of cerebrospinal fluid in patients with neurologic dysfunction. Despite a high risk for infection (upward of 45%), many hospitals lack strict protocols for EVD placement and maintenance. In addition, EVD infections are typically not tracked with the same diligence as central-line catheter infections, because there are no widely accepted standards for routine management of EVDs. ⋯ The following terms were used in this search: EVD, externalized ventricular drains, EVD infections, EVD insertion, EVD Care and Maintenance, Nursing and EVDS. The following databases were utilized by each member of the interdisciplinary team to establish a state of the science on EVD management: American Association of Neurosurgical Surgeons, CINAHL, Cochrane, National Guidelines Clearinghouse, and PubMed. The following common EVD themes were identified: preinsertion hair removal and skin preparation, aseptic technique, catheter selection, monitoring of EVD insertion technique using a "bundle" approach, postinsertion dressing type and frequency of dressing changes, techniques for maintenance and cerebrospinal fluid sampling, duration of catheter placement, staff education/competence, and surveillance.

Comparative Study
Time to Blood Pressure Control Before Thrombolytic Therapy in Patients With Acute Ischemic Stroke: Comparison of Labetalol, Nicardipine, and Hydralazine.
Elevated blood pressure is common in patients with acute ischemic stroke. Thrombolytic therapy is contraindicated in patients with a systolic blood pressure greater than 185 mmHg or diastolic blood pressure greater than 110 mmHg. Elevated blood pressure can lead to a delay in thrombolytic therapy, which is associated with increased morbidity. There is currently insufficient evidence to support the use of a specific antihypertensive agent in this setting. ⋯ Adequate initial dosing of antihypertensive treatment has the potential to reduce time to blood pressure control and possibly time to alteplase therapy. The optimal antihypertensive regimen for controlling blood pressure before alteplase therapy remains unclear.

This systematic review describes effects of body temperature alterations defined as fever, controlled normothermia, and spontaneous or induced hypothermia on outcome after traumatic brain injury (TBI) in adults. ⋯ Setting a goal of normothermia, avoiding fever, and aggressively treating fever may be most important after TBI. Further research is needed to characterize the magnitude and duration of temperature alteration after TBI, determine if temperature alteration influences or predicts neurologic outcome, determine if rate of temperature change influences or predicts neurologic outcome, and compare controlled normothermia versus standard practice or hypothermia.

Insufficient cerebral perfusion pressure (CPP) after aneurysmal subarachnoid hemorrhage can impair cerebral blood flow. We examined the temporal profiles of CPP change and tested whether these profiles were associated with delayed cerebral ischemia (DCI). ⋯ The longer the time patients spent with high CPP, the greater the odds for DCI. When used prophylactically, induced hypertension contributes to higher CPP values. On the basis of the CPP trends and correlations observed, induced hypertension may not confer expected benefits in patients with aneurysmal subarachnoid hemorrhage.

Complex regional pain syndrome (CRPS) is a debilitating condition characterized by specific symptoms such as intense pain and loss of function. This syndrome can be so devastating that it affects quality of life. ⋯ The purpose of the survey in this study was to query actual patients living with CRPS to gain additional knowledge and suggestions to help improve their care. Respondents expressed a variety of emotions when asked about their healthcare experiences, which suggests that healthcare providers need to be better educated about CRPS so they can provide more compassionate care for patients trying to cope with this condition.
