    ObjectiveTo compare the effects of ultrasound-guided serratus anterior plane block (SAPB) and thoracic paravertebral block (TPVB) on postoperative analgesia and inflammation control in patients undergoing upper abdominal surgery.MethodsThis is a retrospective observational study. The records of patients who underwent upper abdominal surgery in our hospital from June 2019 to January 2021 were selected and retrospectively divided into two groups based on the analgesia method. Fifty-nine patients received ultrasound-guided SAPB analgesia (SAPB-group) and 55 patients received ultrasound-guided TPVB analgesia (TPVB-Group). Patients were matched for age, gender and body-mass index (BMI). The visual analogue scale (VAS) scores of pain at two hours(T1), six hours (T2), 12 hours (T3), 24 hours (T4) and 48 hours (T5) after the operation were compared between the two groups. The levels of interleukin-6 (IL-6), interleukin-10(IL-10) and tumor necrosis factor-α (TNF-α) at the completion of surgery (T0) and T4 were compared between the two groups.ResultsThe duration of block in SAPB-group was higher than that in TPVB-group (P<0.05). VAS scores of SAPB-groups were significantly lower than those of TPVB-group at all-time points (P<0.05) except at rest 48 hour after the procedure. The levels of IL-6, IL-10 and TNF-α at 24 hours after the operation in both groups were significantly higher than immediately at the end of the operation (P<0.05). Levels of IL-6 and TNF-α 24 hours after the operation were significantly lower in the SAPB-group than in the TPVB-group (P<0.05), while the levels of IL-10 24 hours after the operation were significantly higher in the SAPB-group (P<0.05).ConclusionsSAPB block under ultrasound guidance for patients undergoing upper abdominal surgery has good anesthetic and analgesic effect and can significantly improve the level of postoperative inflammation.Copyright: © Pakistan Journal of Medical Sciences.
