Alteplase infusion versus dwell for clearance of partially occluded central venous catheters in critically ill pediatric patients.

OBJECTIVE: To evaluate the efficacy and safety of alteplase infusions and alteplase local instillations (dwells) to clear partially occluded central venous catheters in critically ill children. DESIGN: Retrospective study. SETTING: PICU in a single, tertiary care, academic children's hospital. PATIENTS: Retrospective review of the medical records of all critically ill pediatric patients less than 18 years old who received an alteplase infusion or dwell as the treatment for a partial central venous catheter occlusion. The typical infusion regimen was to administer 0.1 mg/kg of body weight (maximum, 2 mg/dose) of alteplase in 25 mL of 0.9% sodium chloride over 3 hours. The standard dwell was to administer and aspirate alteplase in a 1 mg/mL concentration as a fixed dose as ordered by the prescriber (maximum, 2 mg/dose). Efficacy was defined as documentation of positive blood return from the catheter. Radiology reports, nursing and physician documentation, and laboratory values were reviewed to assess for bleeding events. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: One hundred fifty occlusion events were included for analysis. Overall, 72 of 84 alteplase infusions (86%) and 53 of 66 alteplase dwells (80%) resulted in resolution of the lumen occlusion event as documented by positive blood return from the catheter after a maximum of two doses (p = 0.39). One major bleeding event occurred in each arm; both were deemed unlikely related to alteplase. CONCLUSIONS: Alteplase infusions to clear partially occluded central venous catheters appear to be as efficacious as alteplase dwells in critically ill children. In occlusions treated with an infusion, more occlusions resolved in older and larger patients and in patients with catheters in place less than 7 days. In occlusions treated with a dwell, more occlusions resolved in smaller catheters. The safety profile for both infusions and dwells was acceptable for the pediatric critically ill population.

Attitudes of matriculating first-year pharmacy students toward a mandatory, random drug-screening program.

OBJECTIVE: To determine the attitudes of incoming pharmacy students toward a mandatory, random urine drug-screening program. METHODS: This was an anonymous, voluntary survey of students at the McWhorter School of Pharmacy (MSOP) using an instrument composed of 40 items. The instrument was administered during orientation week prior to the session during which the policies and procedures of MSOP's drug-screening program were to be discussed. RESULTS: The survey instrument was completed by all 129 (100%) students in the class. Two-thirds of the students were aware of MSOP's drug-screening program prior to applying, but only a few felt uneasy about applying to the school because of the program. The greatest concerns expressed by the students included what would happen if a student unintentionally missed a drug screen or was busy with other matters when called for screening, how much time a drug-screening would take, and the possibility of false-positive drug screen results. The vast majority of students agreed with statements regarding the potential benefits of drug testing. Students who consumed alcohol in a typical week and those with current or past use of an illegal substance held less favorable attitudes toward MSOP's mandatory drug-screening program compared with students who did not share those characteristics. CONCLUSION: Although there were definite concerns expressed regarding pragmatic issues surrounding drug screening, the first-year pharmacy students held generally favorable opinions about the school's mandatory drug-screening program.
