Comparative Study
A stabilization period of 5 minutes is adequate when measuring pulmonary artery pressures after turning.
To compare hemodynamic measurements made before turning and at 5 and 30 minutes after turning, and to determine whether the stabilization period affects the difference between supine and side-lying pulmonary artery pressures. ⋯ The current practice of turning and settling the patient, zeroing the transducer and proceeding to make the pulmonary artery pressure readings appears to be valid. The stabilization period after turning does not explain the differences found between side-lying and supine pulmonary artery pressures.

Review Case Reports
Management of delirium associated with use of the intra-aortic balloon pump.
Five patients who developed an agitated delirium in association with use of an intra-aortic balloon pump are presented. The differential diagnosis of delirium in critically ill cardiac patients is reviewed and effective pharmacologic treatment strategies (involving rapid and aggressive management with intravenous haloperidol) are discussed.

To describe pediatric critical care nurses' knowledge of dysrhythmias in critically ill pediatric patients and relate this knowledge level to certain demographic variables (education, nursing experience, certification, supplemental training, area of employment and geographic region of residence). ⋯ Pediatric critical care nurses' overall knowledge of dysrhythmias was low. Knowledge strengths included recognition of basic and life-threatening dysrhythmias and calculation of basic ECG measurements. Knowledge deficits included importance of sinus bradycardia in the neonate, appropriate intervention for life-threatening dysrhythmias and calculation of an irregular heart rate. These deficits should be considered when planning continuing education programs for pediatric critical care nurses.

Terminal weaning, withdrawal of mechanical ventilation when the patient is not expected to survive the process, must not be burdensome to the patient or significant others. The healthcare team must individualize the weaning process, considering the physiologic comfort of the patient and the psychoemotional comfort of both the patient and family. The following case studies illustrate variations in a method for terminal weaning that are patient-specific and are based on the experience of a supportive care team.
