Background: Pain control after off-pump coronary artery bypass graft (OPCAB) facilitates mobilization and improves outcomes. The efficacy of the erector spinae plane block (ESPB) after cardiac surgery remains controversial. Methods: We aimed to investigate the analgesic effects of ESPB after OPCAB. Precisely 56 patients receiving OPCAB were randomly divided into ESPB and control groups. The primary outcome was visual analog scale (VAS) pain scores at 6, 12, 24, and 48 h postoperatively. Secondary outcomes were the dose of rescue analgesics in terms of oral morphine milligram equivalents, the dose of antiemetics, the length of intubation time, and the length of stay in the intensive care unit (ICU). Results: The VAS scores were similar at all time points in both groups. The incidence of severe pain (VAS score > 7) was significantly lower in the ESPB group (50% vs. 15.4%; p = 0.008). The dose of rescue analgesics was also lower in the ESPB group (19.04 ± 18.76, 9.83 ± 12.84, p = 0.044) compared with the control group. The other secondary outcomes did not differ significantly between the two groups. Conclusions: ESPB provides analgesic efficacy by reducing the incidence of severe pain and opioid use after OPCAB.
