Background: To compare the analgesic effect of ISB with a combination of ISB-SSNB and patients who were given opioids with
PCA without block in adult patients undergoing shoulder surgery, as measured by opioid consumption and pain intensity in the first 24
hours postoperatively.
Methods: Ninety patients who underwent shoulder surgery were randomly divided into three groups. Group I in which ISB was
performed and patient-controlled analgesia (PCA) was inserted, Group II with; ISB and SSNB combined, and PCA was inserted, and
Group III where; only PCA was used. Visual analog scale (VAS) pain scores at the second, fourth, sixth, 12th, and 24th hours,
morphine consumption, additional analgesic requirement, and patient satisfaction were evaluated.
Results: Compared with Group III, the VAS pain score was significantly lower in Group I and Group II at 2, 4, 6, 12, and 24 hours
postoperatively. In Group I, the VAS score at rest at the 6th hour was found to be higher than in Group II. The 24-hour total morphine
consumption was higher in the control group than in Group I and Group II. The satisfaction score of the control group was lower than
Group I and Group II.
Conclusion: The combined application of ISB and SSNB block is beneficial in shoulder surgery to provide both intraoperative and
postoperative analgesia and opioid consumption.
Level of Evidence: Level I; Randomized Controlled Trial; Treatment Study.
