Randomized Controlled Trial Comparative Study Clinical TrialModulating effects of propofol on metabolic and cardiopulmonary responses to stressful intensive care unit procedures.
Patients in the intensive care unit (ICU) undergo acute increases in metabolic and cardiopulmonary demands in response to routine care interventions, such as chest physical therapy. This study examined whether the short-acting drug, propofol, could blunt the responses to chest physical therapy. ⋯ Propofol, in the doses administered in this study, significantly reduced the hemodynamic and metabolic stresses caused by chest physical therapy.

Critically ill parturient women and admission to intensive care: a 5-year review.
Thirty-nine parturient women were admitted to a general intensive care unit (ICU) from April 1989 to March 1994 and of these four were readmitted (total 43 admissions). Twelve women were admitted to the obstetric unit from peripheral hospitals in different regions, but no requirement for intensive care was perceived on referral. Six women were transfered directly into the intensive care unit from different hospitals in the region. ⋯ A multidisciplinary approach to management is practised and specialist interventions included haemofiltration and haemodialysis (18%) and radiological arterial embolisation (10%). Ventilatory and inotropic support were given in 38% and 41% of patients respectively. Only one patient died on the intensive care unit, this was from multiorgan failure secondary to sepsis.

Comparative StudyInfluence of referring physicians on interventions by a pediatric and neonatal critical care transport team.
The objective of this study was to determine the influence of: a) pediatrician versus nonpediatrician referrals on a transport team's therapeutic interventions and b) referring physician's year of graduation on interventions performed by the transport team. From November 1987 through December 1989 we prospectively compared the therapeutic interventions performed by the critical care transport team on newborns and pediatric patients with the referring physician's specialty and year of graduation. The transport team (critical care physician [PL3 or greater], registered respiratory therapist, critical care nurse), recorded all therapeutic interventions, including both procedural and pharmacologic, for 213 newborn and 149 consecutive pediatric transports. ⋯ We found that the referring physicians' medical training affected the number of interventions their patients received. Similarly, patients were likely to receive more interventions if the referral physicians training was not recent. These data have educational implications and support the concepts of continuing medical education, recertification, and maintenance of skills among physicians providing care to critically ill newborns and pediatric patients.

The purpose in this paper is to consider the importance of early nutrition for critically ill patients, briefly reviewing the effects of malnutrition, and the metabolic response to starvation and sepsis. Discussion includes assessment of nutritional status and nutritional requirements, with a suggested enteral feeding regime; and also the combined effect of enteral nutrition and glutamine on gut integrity and its relevance to nosocomial pneumonia, and the ability of the gut to accept food during critical illness.
