Outcome measures
CPSP, pain, cough, agitation, PONV, NRS
ADVERSE EVENTS, CHRONIC PAIN
The primary outcome was the NRS scores after operation. The NRS scores at rest and cough at 2 h, 6 h, 12 h, 24 and 48 h after operation were observed. Secondary outcomes included the frequency of PCIA use, the frequency of rescue analgesia, the incidence of CPSP, the rating of CPSP effect on daily life, the rating of CPSP management measures, postoperative satisfaction (0–10 points, full score is 10 points), the incidence of agitation during anesthesia recovery, the incidence of PONV, and ESPB-related adverse events.Postoperative follow-up and recording were performed in the ward by the postoperative acute pain management team, which was unaware of the patients’ group. The patients in the two groups were followed up by telephone at 3 months and 6 months after operation. The chronic post-surgical pain (NRS score > 0) was recorded, and the impact of chronic pain on their daily life (no, mild, moderate and severe effects) and the rating of chronic pain management measures (grade A: no treatment measures; Grade B: relief after rest; Grade C: self-purchased medication; Level D: Hospital visits). Telephone follow-up was performed by the same pain management team follow-up member, who was unaware of the patients’ group.
