Heart & lung : the journal of critical care
-
To examine patient characteristics and situational and clinical factors that affect utilization of Emergency Medical Services (EMS) for symptoms of acute myocardial infarction (AMI). ⋯ The findings are discussed in a theoretical context, using Leventhal's self-regulatory model to suggest avenues for future research and interventions.

Randomized Controlled Trial Comparative Study Clinical Trial
Managing pain during mediastinal chest tube removal.
To compare four analgesic regimens used in preparing patients for chest tube removal. ⋯ Blind ratings of subjects' descriptions of sensations suggest subfascial lidocaine may be useful in reducing discomfort during chest tube removal.
-
To study the clinical profile and cholinesterase levels of subjects of organophosphate and carbamate poisoning and to identify those subjects who would require ventilatory support. ⋯ This study helps to identify at an early stage those patients with organophosphate or carbamate poisoning who would ultimately require ventilatory support. We found miosis, unconsciousness, fasciculations, and a low plasma cholinesterase level to be of greatest predictive value.
-
To describe the conflict that occurs during the process of consenting to do-not-resuscitate (DNR) status and the strategies used by critical care nurses to attempt to prevent, minimize, and/or resolve these conflicts. ⋯ Critical care nurses play an active role in assisting patients and families with DNR-status decisions. To better understand the process of consenting to DNR status, additional studies need to focus on the experiences of patients, families, and other health care providers.
-
To evaluate changes in oxygenation as measured by pulse oximetry (SpO2) and saturated venous oxygenation (SvO2) during weaning from mechanical ventilator support. ⋯ Measures of SpO2 and SvO2 are sensitive to changes in oxygenation status during weaning. Although more study is needed, SvO2 measures provide valid information about oxygen status and can be used to guide weaning.
