Closed suctioning system reduces cross-contamination between bronchial system and gastric juices.

In this prospective, randomized study, we evaluated whether a closed suctioning (CS) system (TrachCare) influences crossover contamination between bronchial system and gastric juices when compared with an open suctioning system (OS). The secondary aims were an analysis of the frequency of ventilator-associated pneumonia (VAP) and an analysis of alteration in gas exchange. Antibiograms were performed from tracheal secretions and gastric juice aspirates on Days 1 and 3 of intubation in 24 patients in a medical intensive care unit.

Inhibition of platelet function by hydroxyethyl starch solutions in chronic pain patients undergoing peridural anesthesia.

The use of hydroxyethyl starch (HES) solutions as a fluid replacement before peridural blockade may compromise blood coagulation, thus increasing the risk of neuraxial bleeding. In this prospective, double-blind, placebo-controlled, crossover study, we compared the influence of HES 130 (molecular weight in kilodalton), HES 200, and lactated Ringer's solution on platelet function and hemodynamics in chronic low back pain patients scheduled for peridural blockades. Patients received 3 test infusions of 10 mL/kg each administered IV for 30 min.

Sensor-operated faucets: a possible source of nosocomial infection?

Recently, contamination of sensor-operated faucets (SOFs) with Pseudomonas aeruginosa was observed. To evaluate odds ratios, we conducted a case-control study in which handle-operated faucets served as controls. No statistically significant difference in P.
