OBJECTIVES This study attempted to identify which is the more effective suction system. The objective was to compare open versus closed suction systems according to a systematic review. METHODS A search of scientific literature was conducted in MedLine, LILACS and Cochrane between 1997 and August 2007 using the key words: endotracheal suction and closed suction. Included were articles that co...

Critically ill patients are intubated or tracheostomized because, in most cases, these individuals require invasive mechanical ventilation. The cannulae that are used include the cuff, which can act as a reservoir for oropharyngeal secretions, predisposing to ventilator-associated pneumonia. Studies have revealed that the suction of subglottic secretions through the dorsal suction lumen above t...

The effect of base suction on a plane wake was found to produce significant changes on wake dynamics. The wake is produced by merging two boundary layers from the trailing edge of a splitter plate in a two stream water tunnel. A threshold suction speed exists which is equal to half of the free stream velocity. If the suction speed is below the threshold, the wake flow is unstable. If the suctio...

OBJECTIVES To determine the efficacy of 400 mcg sublingual misoprost as an adjunct to suction evacuation in first trimester pregnancy termination. METHOD(S) During the study period of January2006-June 2007, two hundred twenty-one pregnant women wanting first trimester pregnancy termination were randomised into two groups. In the study group of one hundred twenty-one women, sublingual misopros...

We investigated the microbial contamination of suction tubes attached to wall-type suction instrument. Microbial contamination of suction tubes used for endoscopy or sputum suction in wards was examined before and after their disinfection. In addition, disinfection and washing methods for suction tubes were evaluated. Suction tubes (N=33) before disinfection were contaminated with 102-108 colon...

Background: Different types of endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome is not standardized. Objectives: To compare diagnostic adequacy of aspirated material, cytopathologic and EUS morphological features among capillary action, suction, and no suction FNA methods. Methods: A prospective, single...

Suction is produced during prey capture by most teleost fishes. Here, we ask two questions about the functional basis of suction feeding. First, is there variation in the kinematic pattern produced by different species while suction feeding? Second, do species termed 'suction specialists' demonstrate similar modifications to their feeding behavior? We used 10 kinematic variables in a principal ...
