Glasgow Coma Scale: variation in mortality among permutations of specific total scores.
The objective of this study was to determine whether different score permutations of the Glasgow Coma Scale (GCS) giving the same GCS total score were associated with significantly different mortality. ⋯ It is possible for patients to have the same total GCS score, but significantly different risks of mortality due to differences in the GCS profile making up that score. This suggests that GCS scores may be more useful reported in terms of profiles rather than totals. This could also have implications for the use of other scoring systems such as Acute Physiology and Chronic Health Evaluation and Simplified Acute Physiology Score.

Randomized Controlled Trial Clinical TrialInhaled prostacyclin and platelet function after cardiac surgery and cardiopulmonary bypass.
To study the effects of 6 h inhalation of aerosolized prostacyclin (PGI2) on platelet function. ⋯ Inhalation of PGI2 for 6 h in patients after cardiac surgery is associated with impaired platelet aggregation detected by in vitro techniques, with no in vivo signs of platelet dysfunction.

Comparative StudyAssessment of cardiac preload and extravascular lung water by single transpulmonary thermodilution.
Transpulmonary double-indicator dilution is a useful monitoring technique for measurement of intrathoracic blood volume (ITBV) and extravascular lung water (EVLW). In this study, we compared a simpler approach using single arterial thermodilution derived measurements of ITBV and EVLW with the double-indicator dilution technique. ⋯ Determinations of ITBV and EVLW by single thermodilution agreed closely with the corresponding values from the double-indicator technique. Since transpulmonary single thermodilution is simple to apply, less invasive and cheaper, all these features make it a promising technique for the bedside. Nevertheless, further validation studies are needed in the future.

Monitoring the circulatory responses of shocked patients during fluid resuscitation in the emergency department.
To assess the feasibility of constructing left ventricular response curves non-invasively during the fluid resuscitation of critically ill patients in the emergency department (ED) using a portable suprasternal Doppler ultrasound (PSSDU) device. ⋯ Previous experimental work has shown that changes in central blood flow can be derived using the PSSDU device. This clinical feasibility study suggests that the PSSDU can help tailor haemodynamic therapy for an individual patient and give an early indication of treatment failure in the ED.
