Intravascular rewarming may provide an efficient and reliable method of restoring normal body core temperature in patients, while avoiding after-drop. The system provides continuous temperature monitoring and automatically adjusts warm saline delivery until the desired temperature is reached.
Intermittent and continuous outpatient and home inotrope infusions have contributed to a decreased mortality rate and improved quality of life in the patient with end-stage congestive heat failure. Before the advent of noninvasive hemodynamic monitoring, available with thoracic electrical bioimpedance, initial dosage and titration were determined solely with invasively acquired data requiring hospital admission or with patients' subjective data. Thoracic electrical bioimpedance monitoring of patients receiving inotrope therapy provides objective documentation of drug efficacy, developing tolerance, and optimal dosage.

With the increasing incidence of catheter-related sepsis and recognition of increased mortality and cost of care with pulmonary artery catheters, the need for a safe, cost-effective, and clinically accurate means of obtaining hemodynamic data has become evident. Through the technology of thoracic electrical bioimpedance (TEB), non-invasive hemodynamic monitoring is now possible with the BioZ.com, manufactured by CardioDynamics International Corporation. The BioZ.com provides continuous hemodynamic readings safely, accurately, and inexpensively. TEB is proving to be a valuable adjunct to patient assessment and treatment across multiple health care settings.
Hospital readmission for exacerbation of symptoms of Congestive Heart Failure (CHF) is a major home healthcare problem and expense. To address this problem and curb the increasing expense and patient lifestyle disruption, a group of staff nurses at the Medical University of South Carolina Medical Center developed a nurse-managed clinic to follow all patients with CHF after discharge. Within 6 months of the clinic's operation, readmissions of these patients decreased by 4%, and the length of stay decreased by 1.6 days.

Wolff-Parkinson-White (WPW) syndrome involves connections of myocardial fibers between the atrium and ventricle that can carry electrical impulses outside of the normal conduction system. Treatment options include pharmacologic management, surgical interruption, antitachycardia devices, or transvenous catheter ablation. This is a case study of a patient who underwent surgical ablation of an accessory pathway and reoperation because of continued abnormal conduction. She had tachypalpitations after both procedures and later underwent radiofrequency ablation. Nursing care was complicated because she spoke very little English and was extremely anxious about her illness.
