Quantitative effects of low-dose dopamine on urine output in oliguric surgical intensive care unit patients.
To quantify the magnitude and time course of the effect of low-dose dopamine (2.5 micrograms/kg/min) infusions on urine output in oliguric patients. ⋯ Low-dose dopamine infusion alone produces a drug-dependent increase in urine output in oliguric, euvolemic ICU patients. Maximal effect is temporally variable.

Optimal sedation of mechanically ventilated pediatric critical care patients.
To derive a target range of optimal sedation for the COMFORT Scale and to prospectively test that target range against intensivist assessment of adequacy of sedation. ⋯ Adequacy of sedation is measured more consistently by observers using the COMFORT Scale than by intensivist global assessment.

Comparative StudyDopamine infusion during resuscitation of experimental hemorrhagic shock.
To compare the effects of starting dopamine administration early or late on organ perfusion by measuring tissue oxygen tensions during standard volume resuscitation of hemorrhagic shock. ⋯ Starting dopamine administration early during volume resuscitation in a model of experimental hemorrhagic shock led to higher liver, subcutaneous, and transcutaneous tissue oxygen levels. This finding indicates enhanced tissue oxygen perfusion, especially in the liver.

Pretransport Pediatric Risk of Mortality (PRISM) score underestimates the requirement for intensive care or major interventions during interhospital transport.
To test the hypothesis that a pretransport Pediatric Risk of Mortality (PRISM) score underestimates the requirement for both intensive care and interventions during pediatric interhospital transport. ⋯ PRISM scores determined before interhospital transfer of pediatric patients underestimated the requirement for intensive care and the performance of major interventions in the pretransport setting. Many patients with low PRISM scores required intensive care on admission to the receiving hospital and major interventions during the transport process, and, therefore, were not at "low risk" for clinical deterioration. The PRISM score should not be used as a severity of illness measure or triage tool for pediatric interhospital transport.
