Hypervolemic hemodilution: a new approach to subarachnoid hemorrhage.
Subarachnoid hemorrhage (SAH) refers to the sudden accumulation of blood in the subarachnoid space or in the ventricular system. The hemorrhage may occur with cerebral anomalies, tumors, or trauma. The presence of SAH has been associated with decreases in cerebral blood flow (CBF), which may be attributed in part to increased blood viscosity and hematocrit. ⋯ The dosage is gradually tapered before discontinuation. Effectiveness of the therapy is measured through improvement in neurologic function and regional CBF measurements. The critical care nurse plays a vital role in administering and monitoring the therapy and in educating the family about the disease process and interventions.

Practical aspects of epidural and intrathecal narcotic analgesia in the intensive care setting.
The administration of epidural and intrathecal narcotics is a technique of providing postoperative analgesia that is gaining popularity in many operating rooms, labor suites, and intensive care units. The epidural and intrathecal methods, first introduced a century ago, have been implemented as additional techniques for the administration of narcotic analgesics. Patients who have received epidural or intrathecal narcotics are frequently admitted to the intensive care unit for postoperative care. Because of their continuous proximity to the patient and their monitoring skills, critical care nurses are able to evaluate the analgesic effect and intervene in the event of a complication.

Our purpose was to analyze hospital cost, resource utilization, and outcome by age for a large group of patients who required intensive care unit (ICU) services. Patients in the ICU (N = 6331) were stratified by age groups. Mean hospital cost per patient generally increased with age. ⋯ The current DRG hospital payment system appears to be inequitable for the patient who receives treatment in the ICU during the hospital stay. As hospital operating margins continue to decline because of federal and state DRG hospital payment systems, additional pressures may be applied for physicians, nurses, and health care professionals to cut expenses for these patients. In this effort to watch the bottom line, physicians and nurses must not sacrifice the quality of or the access to care for patients who require ICU services.

Neurogenic pulmonary edema (NPE) is a serious complication associated with various central nervous system insults. Experimental and clinical data support the occurrence of pulmonary edema as a result of neurogenic factors. ⋯ The pathophysiology of this disease is not well understood. We discuss the current theories of NPE, its signs and symptoms, and the nursing management for patients with NPE.

In this prospective study we sought to establish the incidence and nature of lower limb ischemia in patients undergoing treatment with intraaortic balloon pump (IABP) counterpulsation and to determine risk factors for its development. The sample was composed of all 258 balloon catheter insertions or attempted insertions for IABP therapy in 249 patients during a 16-month period. Assessment of the lower limbs, hemodynamic status, and pertinent medications were recorded daily throughout the patient's hospitalization. ⋯ Multivariate logistic regression, which was based on variables found to be significant in univariate analysis, revealed that preexisting peripheral vascular disease, female sex, and diabetes mellitus were related to the development of the whole range of lower limb ischemic problems. Diabetes mellitus, cardiogenic shock, and a history of smoking were associated with major ischemia. Evaluation of risks and benefits before treatment with IABP counterpulsation and careful lower limb assessment before, during, and after counterpulsation may help reduce the complications associated with this lifesaving device.
