Interview assessment of critically Ill patients regarding resuscitation decisions. A case study in ethics research.
To examine how patients perceive and decide their resuscitation status, we monitored 113 admissions to a coronary care unit. We review the research process, including Institutional Review Board concerns, sampling bias and permission by physicians, informed consent, and the patient interview. ⋯ Although standardized psychologic measures indicated distress in some of these critically ill patients, the interview itself induced no detected untoward physiologic or emotional reactions. This pilot study demonstrates the feasibility of assessing patients regarding resuscitation status and also identifies relevant methodologic problems to guide future research of resuscitation decision-making.

Advances in critical care practice have created entire groups of patients that have never before survived. Regardless of the subspecialty of critical care in which you practice, the concept and knowledge of the principles of brain resuscitation must be a core component of critical care practice. The concept of brain resuscitation extends beyond subspecialty boundaries and the boundaries of cardiopulmonary arrest, to include all states of no flow or low flow, which threaten the integrity of neurons.

Propofol infusion for sedation of patients with head injury in intensive care. A preliminary report.
Propofol was given by continuous intravenous infusion to 10 patients with severe head injuries in the intensive care unit. Heart rate, mean arterial blood pressure, intracranial pressure, cerebral perfusion pressure, pupil size and arterial carbon dioxide tension were recorded throughout the study period. A mean infusion rate of 2.88 mg/kg/hour provided satisfactory sedation, and recovery from the propofol was often rapid. Cerebral perfusion pressure was significantly increased at 24 hours.

Colonization of the oropharynx with potentially pathogenic microorganisms (PPM) is a highly significant factor in the pathogenesis of bacterial pneumonia in intensive care patients. Via colonization of the oropharynx, bacteria pass into the tracheobronchial tree, where they can give rise to pneumonia after overcoming pulmonary resistance mechanisms. By a new, prophylactic antibiotic treatment schedule consisting in selective decontamination of the digestive tract (SDD) with locally applied nonabsorbable antibiotics, Stoutenbeek achieved drastic lowering of the colonization and infection rate in trauma patients. ⋯ The SDD schedule proved to be effective with regard to the rate of infection. In the control group, 35 patients developed pneumonia (42%) as against 5 patients receiving SDD prophylaxis (6%). The duration of mechanical ventilation in the patients with pneumonia was 5 days longer than in patients without pneumonia.(ABSTRACT TRUNCATED AT 400 WORDS)
