Summary:Each analgesic protocol was administered to approximately 30% of patients, a finding that may be related to the distribution of the study population into three groups of 30 patients. Because we wanted to make sure that ITMB was superior to other pain control methods performed in our institution, we designed our study to investigate the severity of postoperative pain, as a primary outcome, according to the pain-relief methods. The standard deviation (SD) among the 20 patients was 23.6 mL. [...]a minimum sample size of 27 patients/group was required to afford an α value of 0.05 and a power of 0.8. A randomized setting was considered but rejected due to ethical concerns that IV-PCA alone may provide insufficient pain relief compared with the other two analgesic regimens. [...]it was not possible to determine whether the analgesic results were solely related to the pain relief regimens.
