2.2. Study and Control Groups
In this study, three groups, two experimental and one control group,
were planned and randomization was done by closed envelope method.
Standard perioperative and postoperative analgesia regimen was applied
to the patients in the control group. In addition to this regimen in the
experimental groups, unilateral ACB was applied before the induction of
general anesthesia.
The experimental groups were named as ACB-0.25 and ACB-0.16 according to
the local anesthetic concentration applied. The reason why these
concentrations were chosen will be explained in detail in the discussion
section. The design and process of the study are specified in the
CONSORT diagram (Figure 1).
