Central venous catheters are often mandatory devices when caring for critically ill children. They are required to deliver medications, nutrition, and blood products, as well as for monitoring hemodynamic status and drawing laboratory samples. Any foreign object that is introduced to the body is at risk for infection. Central venous catheters carry a particularly high risk of infection and these infections can be life threatening. Advanced practice nurses possess the power to influence catheter-related line infections in their critical care units. Understanding current recommendations for catheter material selection, site selection, site preparation, and site care can affect rates of catheter-related bloodstream infections. This article discusses risk factors for developing catheter-related bloodstream infections in critically ill children, as well as measures to decrease incidence of catheter-related bloodstream infections, including a review of recommendations from the Centers for Disease Control and Prevention.

Traumatic brain injury is the result of a primary, acute injury and is complicated by the development of secondary injury due to hypotension and hypoxia. Cerebral edema due to brain injury compromises the delivery of essential nutrients and alters normal intracranial pressure. The Monroe-Kellie Doctrine defines the principles of intracranial pressure homeostasis. Treatment for intracranial hypertension is aimed at reducing the volume of 1 of the 3 intracranial compartments, brain tissue, blood, and cerebrospinal fluid. Hyperosmolar therapy is one treatment intervention in the care of patients with severe head injury resulting in cerebral edema and intracranial hypertension. The effect of hyperosmolar solutions on brain tissue was first studied nearly 90 years ago. Since that time, mannitol has become the most widely used hyperosmolar solution to treat elevated intracranial pressure. Increasingly, hypertonic saline solutions are being used as an adjunct to mannitol in basic science research and clinical studies. Hyperosmolar solutions are effective in reducing elevated intracranial pressure through 2 distinct mechanisms: plasma expansion with a resultant decrease in blood hematocrit, reduced blood viscosity, and decreased cerebral blood volume; and the creation of an osmotic gradient that draws cerebral edema fluid from brain tissue into the circulation. The pediatric section of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies adapted previously published guidelines for the treatment of adult brain injury into guidelines for the treatment of children with traumatic brain injury. These guidelines offer recommendations for the management of children with severe head injury, including the use of mannitol and hypertonic saline to treat intracranial hypertension. Acute and critical care pediatric advanced practice nurses caring for children with severe head injury should be familiar with management guidelines and the use of hyperosmolar solutions. The purpose of this article is to assist the advanced practice nurse in understanding the role of hyperosmolar therapy in the treatment of pediatric traumatic brain injury and review current guidelines for the use of mannitol and hypertonic saline.

Increased intracranial pressure reflects the presence of mass effect in the brain and is associated with a poor outcome in children with acute neurological injury. If sustained, it has a negative effect on cerebral blood flow and cerebral perfusion pressure, can cause direct compression of vital cerebral structures, and can lead to herniation. The management of the patient with increased intracranial pressure involves the maintenance of an adequate cerebral perfusion pressure, prevention of intracranial hypertension, and optimization of oxygen delivery. This article reviews the neurological assessment, pathophysiology, and management of increased intracranial pressure in the critically ill child who has sustained an acute neurological injury.

Atrial septal defects have traditionally been repaired by surgical closure. Recently, transcatheter device closure has increasingly been used with excellent results. Although there is limited comparative research evaluating long-term outcomes of the transcatheter technique, preliminary data reveal significantly fewer complications and shorter hospital stays than those reported for surgical repair. This article reviews relevant literature comparing efficacy, cost, and complications of the transcatheter device procedures with the surgical closure of ASDs.

The public has the right to safe, quality healthcare delivered by professionals with the appropriate education, training, and experience. The Joint Commission on Accreditation of Healthcare Organizations, the Accreditation Association for Ambulatory Healthcare, and managed care organizations take this commitment very seriously. One mechanism required by these agencies to ensure patient safety is the process of credentialing and delineation of clinical privileges for medical staff and allied health professionals, such as Acute Care Nurse Practitioners. This commitment extends to patients receiving healthcare through the technology of telemedicine and to those requiring emergency care resulting from trauma, disasters, and varying forms of terrorism. In addition, safeguards must be in place to prevent identity theft of healthcare providers, including Acute Care Nurse Practitioners. It is essential that Acute Care Nurse Practitioners be familiar with the regulations that impact and guide the process of credentialing and obtaining clinical privileges in a variety of venues.

Advanced practice nurses are involved in many aspects of program development as part of their roles. This can involve such things as developing programs for staff and family education, organizing system-wide quality assurance programs, or implementing new care programs. One unique aspect of the advanced practice nurse's role is the ability to serve as a change agent and implement new models of care. Although all advanced practice nurses can be involved in program development, the role of the Clinical Nurse Specialist lends itself to devoting dedicated services for implementing programmatic change in the clinical setting. This article describes the role of the Clinical Nurse Specialist in implementing an evidence-based, fast-track postanesthesia care unit.

Evidenced-based practice (EBP) should be a driving force behind establishing optimal clinical practices. Recently, clinicians and hospitals have started efforts to introduce key EBP. These efforts hold the potential to improve patient outcomes and reduce costs. However, many practices need updating with EBP. Which ones should be chosen? While practices often vary in terms of importance for each hospital, some changes in practice are likely to have a better return on the investment (ROI). Two key areas affecting most hospitals are practices associated with high costs and increased mortality. In critical care areas, these two key areas often involve addressing outlier management and severe sepsis. In addition, the recognition of the need for the change is only one step in ensuring EBP. To ensure EBP is implemented, clinical leaders who will ensure that the new practice standards are being utilized are necessary. Fortunately, many hospitals have strong leaders. The advanced practice nurse (APN) is one such leader. The APN is often in a unique position to help recognize, prioritize, and implement EBP into the hospitals culture. This article illustrates steps in making EBP a reality by highlighting the management of outliers and severe sepsis and the implementation strategies for these conditions.

Programs educating advanced practice nurses (APNs), including acute care nurse practitioners (ACNPs) and clinical nurse specialists (CNSs) may struggle with the degree to which technical and cognitive skills necessary and unique to the care of critically ill patients should be incorporated within training programs, and the best ways these skills can be synthesized and retained for clinical practice. This article describes the critical care technical skills training mechanisms and use of a High-Fidelity Human Simulation (HFHS) Laboratory in the ACNP and CNS programs at the University of Pittsburgh School of Nursing. The mechanisms for teaching invasive procedures are reviewed including an abbreviated course syllabus and documentation tools. The use of HFHS is discussed as a measure to provide students with technical and cognitive preparation to manage critical incidents. The HFHS Laboratory, scenario development and implementation, and the debriefing process are discussed. Critical care technical skills training and the use of simulation in the curriculum have had a favorable response from students and preceptors at the University of Pittsburgh School of Nursing, and have enhanced faculty's ability to prepare APNs.

Advanced practice nurses (APNs) impact both patient care and healthcare systems on a daily basis. Tracking and documenting the outcomes of APN practice have become essential, due partly to the emphasis on outcomes that has become a component of the majority of healthcare initiatives. This article outlines important aspects related to assessing outcomes and discusses the use of quality indicators to demonstrate outcomes of APN practice. Examples from clinical practice are provided in order to demonstrate that assessing the outcomes of APN practice can be incorporated into daily practice as part of ongoing initiatives. In delineating the outcomes of APN care, the value of APNs can be formally acknowledged.

Peer review has multiple manifestations and purposes. Two stated purposes are the demonstration of professionalism and clinical competency. The American Nurses Association (ANA) defines nursing peer-review as a process for evaluating the care provided by an individual according to accepted standards. Further, the ANA proposes that nurses with similar rank and clinical expertise should conduct these evaluations. Some local jurisdictions may also mandate that advanced practice nurses (APNs) review one another's care. Therefore, APNs should become familiar with sources for evaluation criteria and tool formats for APN peer review. The advantages and limitations of the various formats and processes of peer review should also be considered.
