Association between preoperative ultrasound-guided thoracic paravertebral block and chronic postsurgical pain after breast cancer surgery

Objective To evaluate the influence of preoperative ultrasound-guided thoracic paravertebral block (TPVB) on chronic postsurgical pain (CPSP) more than one year after surgery in breast cancer patients using propensity score matching.
Methods Electronic medical records of patients who underwent elective breast cancer surgery between January 2018 and March 2019 were reviewed. The patients were grouped according to whether preoperative ultrasound-guided TPVB was used for surgery: TPVB combined general anesthesia group (group TG) and simple general anesthesia group (group G). Propensity score matching was used to obtain between group balance. Telephone surveys regarding CPSP were conducted were among propensity matched patients where ID-Pain was used to assess neuropathic pain (NP).
Results After propensity matching, 148 patients were included in each group. There was no significant difference in the incidence of CPSP between the two groups, with 64 patients (43.2%) in group TG and 50 patients (33.8%) in group G. The incidence of moderate and severe pain in group TG was lower than that in group G, and the incidence of NP was higher than that in group G, but the difference was not statistically significant. The CPSP NRS score in group TG was 2 (1-3) points, and the CPSP NRS score in the G group was 2 (1-4) points. The CPSP pain levels of the two groups were mild pain, and the difference was not statistically significant.
Conclusion There is no association between preoperative ultrasound-guided TPVB and reduced incidence of CPSP more than one year after surgery in breast cancer patients.
