Randomized Controlled Trial Clinical TrialErythromycin facilitates postpyloric placement of nasoduodenal feeding tubes in intensive care unit patients: randomized, double-blinded, placebo-controlled trial.
To determine whether administration of erythromycin (E) could facilitate passage of a nasoenteric feeding tube into the duodenum for postpyloric feedings, this randomized, double-blind, placebo-controlled trial was performed. ⋯ These data suggest that, overall, E is effective in facilitating placement of a nasoenteric feeding tube into the duodenum in ICU patients. It is clearly beneficial in those patients with normal mental status and may be useful in patients with diabetes mellitus.

Influence of different volume therapy regimens on regulators of the circulation in the critically ill.
Various vasoactive substances are involved in the regulation of the macro- and microcirculation. We have investigated if these regulators change during long-term volume therapy with human albumin (HA) or hydroxyethylstarch solution (HES) in trauma and sepsis patients. To maintain pulmonary capillary wedge pressure (PCWP) at 10-15 mm Hg, either 20% HA (HA-trauma, n = 14; HA-sepsis, n = 14) or 10% low-molecular weight HES solution (HES-trauma, n = 14; HES-sepsis, n = 14) were infused for 5 days, otherwise patient management did not differ between the two groups (trauma/sepsis). ⋯ In both sepsis groups, vasopressors (vasopressin, endothelin-1, noradrenaline and adrenaline) were significantly increased above normal at baseline and decreased more markedly in HES than in HA patients. Concentrations of atrial natriuretic peptide increased only in the HA patients (from 159 (SD 31) to 215 (38) pg ml-1 on day 2). Plasma concentrations of 6-keto-prostaglandin F1 alpha decreased significantly only in the HES sepsis patients (from 112 (25) to 47 (15) pg ml-1).

Randomized Controlled Trial Clinical Trial
Evaluation of a hospital-based youth violence intervention.
To decrease adolescent morbidity and mortality and improve the quality of life, a violence-prevention consultation is offered to hospitalized victims of nondomestic violence. The context is a violence-prevention team approach to patient assessment, treatment, and follow-up. Psychoeducational counseling emphasizes the individual through a cognitive behavioral approach and also recognizes the individual in the proximal social setting through referrals to community resources. ⋯ No statistically significant differences between intervention subjects and nonintervention controls in terms of baseline variables have been observed. For inner-city adolescent victims of violent assaults, a hospital-based intervention offers a unique opportunity for reduction of the incidence of reinjury. We describe the elements of the intervention, including the theoretical basis and implementation; detail the overall evaluation design including modifications; and present preliminary analyses of baseline data.

Randomized Controlled Trial Multicenter Study Clinical TrialGamma radiation-sterilized, triple-lumen catheters coated with a low concentration of chlorhexidine were not efficacious at preventing catheter infections in intensive care unit patients.
In a randomized, double-blind trial, gamma radiation-sterilized, chlorhexidine-coated triple-lumen catheters were compared with uncoated control catheters for their ability to prevent catheter infection in 254 intensive care unit patients. The chlorhexidine coating was not efficacious, and a rabbit model demonstrated that reduction of chlorhexidine activity by gamma radiation sterilization was the likely explanation for the failure.

Randomized Controlled Trial Comparative Study Clinical TrialMicrobial contamination of blood conservation devices during routine use in the critical care setting: results of a prospective, randomized trial.
To compare microbial contamination of two different blood conservation devices; to determine if there was an association between contamination of the blood conservation devices and clinical infections; to determine if there was a significant user preference for either of the two devices. ⋯ The levels of microbial contamination noted in these devices were not consistent with clinical infection (defined as 10(3) cfu/mL on quantitative cultures). There was no significant difference in degree or pattern of contamination between the two devices. When utilized and changed according to the Centers for Disease Control guidelines, blood conservation devices are not harbors of infection in the critical care setting. Blood conservation devices can be used as part of a comprehensive blood conservation program in the critical care setting without undue concern for exacerbating infectious processes.
