Ley, Miller Skov, and Preisig. This critique outlines answers for ten central questions about the focus of the study, research design and outcomes. 1. Did
the study ask a clearly focused question? (consider population, intervention and outcomes). The researchers offer two specific and clearly questions that direct the central research process. These questions
are: 1. Are crystalloids or colloids more effective in promoting stability in terms of hemodynamics following cardiac surgery? and 2. What is the rate and amount of
IV fluid replacement that should occur immediately following cardiac surgery (post-operative period). These questions relate to the population (individuals going through cardiac surgery), the interventions (using either crystalloids or
colloids in IV fluid replacement) and the outcomes (which determine optimal recovery). 2. Was this a RCT (Randomised control trial) and was it appropriately so? (consider
why this was an RCT and was this the right approach, could another approach have been taken). The focus of the hypotheses presented suggests that colloid therapy will provider greater
positive outcomes and promote optimal recovery, and so the research questions focus on colloids vs. crystalloids as the IV fluids provided. As a result, the researchers randomly assigned individuals
to either the group receiving colloids or the group receiving crystalloids, the colloids group being the experimental group and the crystalloids group existing as the control. As a result,
it can be argued that the researchers have selected a randomised control trial and that it was appropriate to do so in light of the hypotheses they presented. 3.
Were participants appropriately allocated to intervention/control groups? (consider how allocation occurred, was it truly random, was method described, was any stratification used, how was the randomisation generated and people
