To describe the red blood cell transfusion practices of pediatric intensivists. ⋯ This survey documented a significant variation in transfusion practice patterns among pediatric critical care practitioners with respect to the threshold hemoglobin concentration for red blood cell transfusion. The volume of packed red blood cells given was not adjusted to the hemoglobin concentration.

Alternative arterial catheterization site using the ulnar artery in critically ill pediatric patients.
To examine the patterns of usage and associated complications among radial, femoral, and ulnar artery catheters in the pediatric intensive care unit to ascertain the utility of the ulnar artery as an alternative vessel of peripheral cannulation. ⋯ Based on the ischemic and infectious complication rates, the ulnar artery should be considered as a viable site for peripheral vessel cannulation in cases in which arterial catheterization is necessary and attempts at more common sites of catheterization are unsuccessful.

Capillary and arterial blood gases in hemorrhagic shock: a comparative study.
To determine whether capillary blood gas samples accurately reflect the information obtained from arterial blood gas samples in a porcine hemorrhagic shock model. ⋯ Capillary blood gas samples are poor predictors of Pco2 and pH in porcine hemorrhagic shock. These findings should be taken into account when capillary blood gas samples are used in the monitoring and management of subjects diagnosed with shock.

Comparison of end-tidal CO2 and Paco2 in children receiving mechanical ventilation.
To determine whether end-tidal CO(2) (Petco(2)) measurement provides a reliable estimate of ventilation in critically ill children who are mechanically ventilated. DESIGN: Prospective, nonrandomized, consecutive enrollment study. SETTING: A university-affiliated children's hospital pediatric intensive care unit. PATIENTS: All intubated, mechanically ventilated pediatric patients. INTERVENTIONS: All Petco(2)-Paco(2) pairs were from patients ventilated with a Servo 300 Ventilator (Siemens-Elema AB, Stockholm, Sweden). When a blood gas sample was obtained, Petco(2) as measured by a continuous mainstream Petco(2) capnograph was recorded. Measurements: The results of blood gas measurements and corresponding Petco(2) measurements were recorded. Demographic data and primary diagnosis were noted. Petco(2)-Paco(2) pairs obtained from patients with intracardiac shunts or obtained during high-frequency oscillation or extracorporeal membrane oxygenation at the time of measurement were excluded from analysis. Linear regression was used to analyze Petco(2)-Paco(2) pairs. Repeated measure analysis of variance with the mixed-model algorithm in SAS software (SAS Institute, Carey, NC) was used to analyze the trend in the Petco(2) and Paco(2) relationship. Chi-square was used to analyze categorical data. Statistical significance was considered p <.05. ⋯ In most intubated, mechanically ventilated infants and children, Petco(2) reliably estimates ventilation.
