In this paper, systematic review and meta-analysis are used to evaluate the role of pecto⁃intercostal fascial block (PIFB) in multimodal analgesia after cardiac surgery. Computer search PubMed, Embase, the Cochrane Library, CNKI, Wanfang and other Chinese and English databases. A randomized controlled trial (RCT) study comparing PIFB and a control group (without nerve block) for postoperative analgesia after cardiac surgery, published in Chinese and English, from database establishment to March 2024. According to the Cochrane manual, literatures were selected, data were extracted, methodological quality of the included literatures was evaluated, and meta-analysis was performed using RevMan5.4. Finally, 3 RCTS were included, with a total of 179 patients. Compared with the control group, the experimental group can reduce the resting pain score at 4h (MD=-1.89; 95%CI -2.10 ~ -1.67, P<0.00001), 8h (MD=-1.43; 95% CI-1.67 ~ -1.18, P<0.00001), 12h (MD=-1.35, P=0.02). 95% CI-1.53 ~ -1.16, P<0.00001) and 24h (MD=-0.45; 95%CI -0.69 ~ -0.21, P=0.0002) after cardiac surgery, the exercise pain score at 12h (MD=-0.93; 95%CI -1.18 ~ -0.69, P<0.00001) after surgery, and reduce the intraoperative sufentanil consumption (MD=-18.44; 95%CI -22.45 ~ -14.43, P<0.00001), postoperative extubation time (MD=-46.06; 95%CI -58.62 ~ -33.51, P<0.00001) and postoperative ICU stay time (MD=-3.47; 95%CI -4.85 ~ -2.09, P<0.00001). There was no significant difference in the total hospitalization time (MD=-0.30; 95%CI -0.65 ~ 0.05, P=0.09) between the two groups. Adding PIFB in postoperative multimodal analgesia can effectively control postoperative pain, reduce intraoperative opioid consumption, and help patients recover quickly after surgery.
