E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Does a fluid challenge give an increase in plasmavolume, measured as a dilution of the red blood cells, during bariatric surgery? Does acetated Ringers give a similar plasmavolume increase as albumin solutions both in size and in length? |
Ger en ”fluid challenge” en ökning av plasmavolymen, mätt som utspädning av de röda blodkropparna, vid laparoskopisk kirurgi? Ger Ringeracetat en likvärdig plasmavolymsökning vad gäller storlek och duration som albuminlösningar?
|
|
E.2.2 | Secondary objectives of the trial |
Is there a correlation between volume effect and circulatory effects, such as blood pressure and cardiac output? Does "fluid challenge" with acetated Ringers resilt in a clinical relevant effect (plasma volume and cardiac output) on the longer run? In the perspective of 24 hours, does the choise of fluid have any importance for the fluid balance of the body? How are kidney function markers and arterial blood gases influenced by the three different fluid therapies? |
Korrelerar plasmavolymsförändringar med cirkulationsfysiologiska parametrar? Har ”fluid challenge” med Ringer-acetat någon klinisk relevant effekt (plasmavolym och hjärtminutvolym) på lite längre sikt? Kan man uppnå likvärdig effekt med mindre volym, dvs hyperonkotiskt albumin? Har det på ett dygns perspektiv någon betydelse, för kroppens vätskebalans, vilken vätska som används för volymsbelastning? Hur påverkas njurfunktions markörer och blodgaser av de tre olika terapierna?
