Question

Experiment research involves manipulating one variable to determine if changes in one variable cause changes in another variable. When this method is used by researchers, it allows them to establish causality. One example found in the GCU library is the study "bupivacaine infiltration for acute postoperative pain management after cardiac surgery". The study was to assess the effectiveness of injecting 0.5% bupivacaine in the wound for patients who underwent cardiac surgery with sternotomy. It looked at this method of pain management during the immediate post operative period for these patients and used a single-center non-randomized experimental design (Oliveros et, al., 2022). Participants are randomly assigned which helps to ensure that any differences in the outcomes are due to the intervention rather than other factors.
