Abstract:Objective To evaluate the postoperative analgesia effect of ultrasound-guided erector spine plane block (ESPB) versus thoracic paravertebral nerve block (TPVB) for thoracoscopic lobectomy in adults.Methods Database including PubMed, Embase, Cochrane-Library, CNKI, WanFang and VIP databases were searched from the beginning to January 2022. Collect RCT about postoperative analgesic efficacy of ESPB versus TPVB for adult thoracoscopic lobectomy. RevMan 5.3 software was used to analysis primary outcomes [visual analogue scale (VAS) at 6, 12, 24 and 48h after surgery) and secondary outcomes (the time of perform nerve block procedure, incidence of postoperative adverse events, remedial analgesia rate at 24 h postoperatively, and number of postoperative analgesic pump presses).Results 16 RCT with 951 patients were included. The results of Meta-analysis showed that: there were no statistically significant differences between the ESPB group and the TPVB group in the rest and exercise VAS at 6 h (MD rest = 0.04, 95%CI: -0.15~0.22; MD exercise = 0.10, 95%CI: -0.07~0.28), 12 h (MD rest = 0.36, 95%CI: -0.01 ~ 0.73; MD exercise = 0.34, 95%CI: -0.10~0.78), 24 h (MD rest = 0.26, 95%CI: -0.44 ~ 0.96; MD exercise = 0.52, 95%CI: -0.40 ~ 1.43), 48 h (MD rest = 0.05,95%CI:-0.20~0.31;MD exercise = 0.11,95%CI: -0.19 ~ 0.40) after surgery, the remedial analgesia rate at 24 h after surgery (OR^ = 1.37, 95%CI: 0.52~3.63), the incidence of postoperative nausea and vomiting (OR^ = 1.25, 95%CI: 0.82 ~ 1.89), skin itching (OR^ = 0.86, 95%CI: 0.39 ~ 1.86), chest tightness (OR^ = 0.59, 95%CI: 0.07 ~ 4.63), and the number of analgesia pump presses (MD = -0.10, 95%CI: -0.28 ~ 0.08). Compared with the TPVB group, the time to complete nerve block operation (MD = -2.40, 95%CI: -3.25 ~ -1.55) was shorter, and the incidence of postoperative hypotension (OR^ = 0.29, 95%CI: 0.13 ~ 0.66) was lower in the ESPB group.Conclusion Ultrasound-guided ESPB provides identical effective analgesia with TPVB, however, ESPB is easier to operate and has a lower incidence of postoperative hypotension, so recommend the use of ESPB as an alternative to perioperative analgesic for adult thoracoscopic lobectomy.
