Background: This study was to determine the analgesic effect of ultrasound-guided erector spinae plane block (ESPB) and paravertebral block (PVB) as well as the combination of PVB and ESPB (P + E) after video-assisted thoracoscopic surgery (VATS). Patients and Methods: Patients were randomly assigned to receive ESPB, PVB or PVB combined with ESPB with 0.5% ropivacaine (20 ml). The primary outcomes were cumulative hydromorphone consumption and Visual Analogue Scale (VAS) scores at rest and while coughing at 0 h, 12 h, 24 h, 48 h and 72 h postoperatively. The secondary outcomes were effective PCA usage count and rescue analgesia requirement at the same time points. Results: The median (interquartile range) hydromorphone consumption, including converted oxycodone, was significantly different at 48 h postoperatively among the three groups (ESPB, 10.24 [9.53–11.71] mg; PVB, 9.94 [9.19–10.75] mg; P + E, 9.44 [8.96–9.97] mg; P = 0.011). Hydromorphone consumption in P + E group was lower compared with that in ESPB group at 12 h, 24 h and 48 h (P < 0.001, P = 0.004 and P = 0.003, respectively). VAS scores at rest were significantly higher for ESPB group compared to P + E group at 0 h postoperatively (P = 0.009). VAS scores while coughing were significantly higher for ESPB group compared to P + E group at 0 h and 12 h postoperatively (P = 0.015 and P < 0.001) and to the PVB group at 12 h postoperatively (P = 0.002). The effective PCA usage count in P + E group was lower than in ESPB group in 0–12 h (P < 0.001). More patients needed rescue analgesia in ESPB group compared to those in P + E group in 0–12 h, 0–24 h and 0–48 h (P = 0.022, 0.035 and 0.035, respectively). Conclusions: Ultrasound-guided PVB combined with ESPB provided superior analgesia to ESPB for VATS. The combination of PVB and ESPB had a similar analgesic effect compared with PVB alone.
