Complications of central venous catheterization in critically ill children.
Analysis of central venous catheterization complications in different access sites with the Seldinger technique. Patients and Methods: A prospective study (May 1992 through December 1996) of 308 central venous catheterizations in children of different ages in a pediatric intensive care unit. ⋯ Central venous catheterization can be performed readily in children of all ages with an acceptable degree of risk. The immediate complications were more frequent and severe for subclavian vein catheterization, and the highest risk factor was the number of attempts at catheter insertion. Although the most frequent late complications were mechanical, which were higher for the femoral access and long-indwelling catheters, femoral catheters can be left indwelling for longer periods if routine ultrasound follow-up is performed. Infectious complications were independent of the venous access site or the duration of catheterization.

To investigate the frequency, predisposing factors, clinical presentation, and outcome of abdominal compartment syndrome (ACS) in critically ill pediatric patients. DESIGN: A prospective study over a 5-yr period. SETTING: Pediatric intensive care unit of a tertiary care, university hospital. PATIENTS: All patients admitted to the pediatric intensive care unit were screened for the presence of ACS and were treated with a uniform protocol. ACS was defined as abdominal distention with intra-abdominal pressure (IAP) > 15 mm Hg, accompanied by at least two of the following: oliguria or anuria; respiratory decompensation; hypotension or shock; metabolic acidosis. MEASUREMENTS AND MAIN ⋯ Although relatively infrequent compared with adults, ACS occurs in critically ill children. Timely decompression of the abdomen results in uniform improvement, but overall mortality is still high. In contrast with adults, children with ACS have diverse primary diagnoses, with a significant number of primary extra-abdominal-mainly central nervous system-conditions. Ischemia and reperfusion injury appear to be the major mechanisms for development of ACS in children. Clinical presentation is similar to adults, but children may develop ACS at a lower IAP (as low as 16 mm Hg).

Comparison of resource utilization and outcome between pediatric and adult intensive care unit patients.
To compare resource utilization and outcomes between cohorts of pediatric and adult intensive care unit (ICU) patients from a single institution. DESIGN: Prospective, observational cohort study. SETTING: A large, urban, tertiary care medical center. PATIENTS: A total of 780 patients consecutively admitted to the pediatric ICU, adult medical ICU, and adult surgical ICU. MEASUREMENTS AND MAIN ⋯ Pediatric critical care patients have better short-term and longer-term survival compared with adult patients. The difference in survival is accounted for by the lower survival of adult medical patients. Despite the survival differences, pediatric and adult ICU patients incur similar hospital costs, and the proportions of patients who receive active ICU interventions are similar.

Amrinone in pediatric refractory septic shock: An open-label pharmacodynamic study.
To investigate the short-term hemodynamic effects of amrinone in pediatric patients with refractory septic shock. DESIGN: Open-label, clinical trial. SETTING: Pediatric intensive care unit. PATIENTS: Nine patients admitted with a diagnosis of septic shock receiving stable doses of vasopressors and inotropes. INTERVENTIONS: Pediatric patients with septic shock and a pulmonary artery catheter were treated with amrinone in a stepwise fashion at 5, 10, and 15 &mgr;g/kg/min. MEASUREMENTS AND MAIN ⋯ In this short-term, dose-response study in children with refractory septic shock, amrinone improved cardiac index and oxygen delivery in pediatric patients with refractory septic shock without increasing myocardial work.

Relevance of diagnostic diversity and patient volumes for quality and length of stay in pediatric intensive care units.
Investigation of associations of the diagnostic diversity and volumes with efficiency and quality of care. ⋯ Patient volumes encountered in a PICU are important for maintaining quality and efficiency of care. In low-volume units, fewer diagnoses and higher volumes were both associated with higher efficiencies. In high volume units, diagnosis-specific volumes were generally large enough for achieving diagnosis-independent efficiency. Diagnostic mix was not associated with PICU mortality ratios, but higher PICU volumes were associated with lower mortality rates.
