Välutbildade skolledare ses som en viktig faktor i utveckling av den lokala skolan. År 2010 blev därför Rektorsprogrammet en obligatorisk utbildning på avancerad akademisk nivå. I en undersökning följer vi en grupp rektorer under de tre år de deltar i programmet. I denna artikel presenteras resultatet av en delstudie i den mer omfattande undersökningen om rektorer i utbildning. Under utbildningen är deltagarna organiserade i ”lärgrupper” i vilka de förväntas arbeta och lära tillsammans. Intentionen är också att ge rektorerna erfarenheter av ett lärande i samspel med kollegor. Delstudiens syfte är att undersöka och förstå rektorernas beskrivningar av de aktiviteter som sker inom studiegruppen. Forskningsfrågor är: 1. Vilka drivkrafter är möjliga att identifiera i rektorers beskrivning av de aktiviteter som sker inom lärgrupperna? 2. Vad möjliggör och begränsar det gemensamma lärandet inom lärgrupperna? Materialet analyseras med hjälp av teorin om praktikarkitekturer.
BackgroundBacterial mediastinitis is a severe complication after open heart surgery. The infection causes prolonged hospitalization and an increased mortality risk. Observations from orthopaedic surgery showed that the suction catheter used during surgery is commonly contaminated with bacteria. The aim of this study was to describe the prevalence of suction catheter contamination in cardiac surgery and to study if suction time influences the contamination risk.MethodsFifty suction catheter tips were collected during 25 aortic valve replacement operations. The suction tip was exchanged once during the operation (after aortotomy closure). The tips were subjected to bacterial contamination analysis.ResultsIn 20 of the 25 investigated cases (80%), bacterial contamination was detected on one or both tips. The tip used during the beginning of the operation showed bacterial contamination in 13/25 cases (52%) and the second tip in 12/25 (48%). In 5/25 cases (20%) both tips were contaminated. There was no association between bacterial contamination and suction time. Coagulase-negative staphylococcus was the most commonly detected microorganism.ConclusionsThe suction device should be considered as a potential source of bacterial contamination in cardiac surgery. The results suggest that the suction catheter should be replaced before key moments like valve implantation and sternal closure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
